THE ANESTHESIA CONSULTANT

Anesthesiologists work with surgeons of every specialty. Remarkable surgeons made world-changing breakthroughs during the past 70 years. The top 10 surgical advances during this time included:

• THE HEART-LUNG MACHINE
• ARTHROSCOPY
• HEART TRANSPLANTATION
• THE FIBEROPTIC ENDOSCOPE
• VIDEOLAPAROSCOPY
• INTERVENTIONAL RADIOLOGY/ANGIOPLASTY/STENTS
• LIVER TRANSPLANTATION
• TOTAL JOINT REPLACEMENT
• LASIK
• TRANSCATHETER AORTIC VALVE REPLACEMENT (TAVR)

 

THE LIST IN ROUGHLY CHRONOLOGIC ORDER:

• THE HEART-LUNG MACHINE AND OPEN HEART SURGERY. Inventor: Dr. John Gibbon (1950s). The heart-lung machine made coronary artery bypass surgery and open heart surgery possible. Prior to the machine, it was impossible to successfully operate on the heart while it was still beating. The invention of the cardiopulmonary bypass pump, or heart-lung machine, allowed blood to bypass the heart during surgery. The machine is attached to the veins that enter the heart and to the arteries that exit the heart. The machine then extracts blood from the patient, adds oxygen to it and pumps it back around the body, ensuring that all the organs receive oxygen while the heart is stopped. Dr. Gibbon carried out his initial research using cats and dogs. In 1953 he performed the first successful operation on a human using the heart-lung machine. In the 1980s researchers found that by cooling the heart to below 28°C and treating it with cardioplegic chemicals, the heart could be stopped for hours while complex surgeries were performed. The heart could then be restarted with minimal damage.

• ARTHROSCOPY. Dr. Inventor: Dr. Masaki Watanabe (1960s- 1980s). The Japanese orthopedic surgeon Dr. Watanabe is widely considered the father of modern arthroscopy.  In 1962 he performed the first arthroscopic knee surgery and meniscectomy using instruments he developed. Watanabe developed his arthroscope from a pediatric cystoscope. Prior to the arthroscope, this surgery required the surgeon to open the joint to operate directly on the meniscus. Six weeks after this first arthroscopy, the patient was playing basketball.  In 1965 Dr. Robert Jackson brought the technique from Japan to the Toronto General Hospital in North America.

• HEART TRANSPLANTATION. Inventor: Dr. Norman Shumway (1960s-1980s). Dr. Shumway spent decades working on the science of heart transplantation in the dog laboratory. In 1959 Shumway successfully performed the first dog heart transplantation. On November 20, 1967 Shumway announced that Stanford was ready to perform the first human heart transplant. Two weeks later South African surgeon Dr. Christiaan Barnard surprised Shumway and the entire world by using Shumway’s surgical technique to perform the first human heart transplant. The patient lived only 18 days. On January 6, 1968, Shumway performed the first successful heart transplant in America at Stanford University Hospital. Shumway’s program grew in the 1980s after the discovery of the immunosuppressive drug cyclosporine, which decreased the transplant rejection rate and improved survival. In 2023, 110 hospitals in the U.S. performed heart transplantation, and the procedure is saving lives of patients with severe cardiomyopathies.

• THE FIBEROPTIC ENDOSCOPE. Inventors: Dr. Larry Curtis and Dr. Basil Hirschowitz (1950s – 1960s). Prior to 1960, views into the colon or upper gastrointestinal tract were only possible via rigid metal tubes. In the late 1950s, Larry Curtiss and Dr. Basil Hirschowitz invented a modern optical fiber scope at the University of Michigan. In 1960 the first commercial fiberoptic endoscope, the American Cystoscopy Makers Model 4990, was introduced. The flexible fiberoptic endoscope revolutionized the practice of gastroenterology, and enabled physicians to visualize the colon, esophagus, stomach, and duodenum—locations previously only visible to a surgeon or a pathologist.

• VIDEOLAPAROSCOPY. Inventor: Dr. Camran Nezhat (1970s-1980s). Dr. Nezhat is widely recognized as the father of operative videolaparoscopy, a technique which revolutionized noninvasive surgery. During his gynecology residency, Dr. Nezhat was exposed to laparoscopy as a diagnostic tool. In the late 1970s he began using a video camera rigged to the end of the laparoscope for animal surgeries. He introduced the technique of operating while watching video camera images on a television monitor, rather than placing a single eye onto the end of an endoscope. Nezhat perfected laparoscopic operative repairs for management of multiple diseases of the pelvis and abdomen, and demonstrated the advantages of laparoscopic surgery: shorter hospital stays, smaller incisions, and faster recovery. He also showed that, when performed by an experienced surgeon, laparoscopic surgery is associated with fewer complications and better results than open laparotomy.

• INTERVENTIONAL RADIOLOGY CATHETER PROCEDURES. Inventor: Dr. Andreas Grüntzig (1970s). Atherosclerosis in arterial blood vessels represents a major cause of illness and death in the world. In 1974 German-born Dr. Andreas Grüntzig first utilized a balloon-tipped catheter to reopen a narrowed femoral artery, a procedure he initially called “percutaneous transluminal dilatation.”  His first successful coronary angioplasty dilation on an awake human was performed in 1977 in Switzerland. He expanded a stenosed 3 mm non-branching section of the left anterior descending coronary artery. Balloon angioplasty replaced many open coronary artery bypass surgeries, and along with intravascular stenting became the method of choice to treat patients with significant coronary artery disease. The same technology is useful to treat patients with occluded leg arteries. Interventional radiology procedures on the brain and other organs have expanded this realm into new surgical subspecialties.

  • LIVER TRANSPLANTATION. Inventor: Thomas Starzl MD PhD (1960s-1980s). Dr. Starzl conducted more than 150 dog experiments on liver transplantation between 1958-1961. He performed the first attempted human liver transplant in1963, but the patient died intraoperatively due to uncontrolled bleeding. In 1967 Starzl performed a liver transplant on a 19-month-old girl who survived for over one year. In the 1980s, with the addition of cyclosporine immunosuppression for his transplant patients, Starzl’s program at the University of Pittsburgh established liver transplantation as a viable option to treat end-stage liver failure. In 1989 the New England Journal of Medicine (321:1014-1022, 1989; 321:1092-1099, 1989) stated: “The conceptual appeal of liver transplantation is so great that the procedure may come to mind as a last resort for virtually every patient with lethal hepatic disease.” As liver transplantation became widespread, almost every liver program director could trace their educational background to Dr. Starzl.

• TOTAL JOINT REPLACEMENTS. Inventor: Dr. John Charnley (1960s-1980s). He was born in England in 1911, and was trained as a general surgeon. During World War II he was stationed as an orthopedic officer in Cairo, where he invented a variety of surgical instruments. After the war he became a consultant orthopedic surgeon in England. He performed experiments on joint function, directed at understanding the friction and lubrication of animal and artificial joints. He tested a new material: ultra-high molecular weight polyethylene (UHMWP), which had the favorable qualities of excellent wear resistance, low friction, and high impact. In 1962 Charnley inserted the first UHMWP socket into a hip joint. He also introduced the use of methyl methacrylate as a plastic cement to firmly affix prosthetic components to the bone. His pioneering work on joint prosthetics changed orthopedic surgery forever.

 

• LASIK (Laser-Assisted in Situ Keratomileusis) Inventors: Dr. Gholam Peyman and Dr. Ioannis Pallikaris (1980s-1990s). In 1989 Dr. Peyman received a patent for his method of modifying the corneal curvature of the eye with a laser surgical procedure in which a flap was cut in the cornea, the flap was pulled back to expose the corneal bed, the exposed surface was ablated, and the flap replaced. Using this technique, Dr. Pallikaris performed the first laser-assisted in situ keratomileusis (LASIK) in 1992. LASIK became a popular refractive surgery which produced immediate vision correction with few side effects. LASIK is currently the world’s most popular elective surgical procedure, as more than 28 million LASIK surgeries have been performed worldwide.

 

• TRANSCATHETER AORTIC VALVE REPLACEMENT (TAVR). Inventors: Dr. Henning Rud Andersen and Dr. Alain Cribier (1989-2000s).  Dr. Alain Cribier performed the first catheter valve implantation in a human in France in 2002.  Prior to the TAVR procedure, replacement of a heart valve required general anesthesia, a heart-lung bypass machine and open heart surgery, to enable a surgeon to directly sew a new valve prosthesis into place. The development of TAVR enabled replacement of the aortic valve via a femoral artery approach, and significantly improved safety and patient outcomes. TAVR use has expanded so that it’s now a mainstream treatment for aortic valve disease. The 30-day mortality after TAVR has decreased from 7.2% to 2.5%, and the incidence of stroke has fallen from 2.75% to 2.3%.  Highly trained cardiologists can now replace any of the four heart valves via a similar transcatheter technique, and some replacements can be done via the radial artery rather than using the femoral artery.

These are the 10 biggest leaps in surgical history in the past 70 years, as seen through the eyes of this anesthesiologist. It’s been a remarkable era in medicine, and one can only speculate if the next 70 years can possibly bring an equivalent revolution in the practice of surgery.

AN ANESTHESIA STORY LIKE NO OTHER

THE ANESTHESIA CONSULTANT

I’m an anesthesiologist, and I like to tell stories. This one is true. If you wonder how much the anesthesia scene has changed significantly over the past four decades, check out this narrative:

In 1986 I was in my second and final year of anesthesia residency training at Stanford, and I was looking for a job. The entire program was 24 months long in those days. We were all due to graduate from the residency on the 30th of June, and in the middle of the second year it was routine to begin searching for a full time job to begin in July. I heard about an opening with a busy private practice anesthesia group in Southern California. I contacted the group via telephone, mailed them my resume, and they invited me to travel to their hospital for an interview. I was excited. The prospect of a full time private practice job was enticing.

When I arrived at their hospital, I donned scrubs and was ushered from operating room to operating room to meet 15 or 20 attending anesthesiologists while they worked. The hospital was stylish and clean, the medical personnel were friendly, and the anesthesia work looked familiar, with no significant differences from what I’d seen during my training.

A month later they invited me back to the second step of their vetting process—an oral board-type exam where I was questioned by ten members of their group. They told me their exam would be “more difficult than the American Board of Anesthesiology oral exam.” The actual exam room was an imposing setting, with ten partners in the group sitting around a semicircular table with me at the center. Their questions were difficult. One I still remember was “a 3-year-old child is hit in the eye by a rock thrown from a lawnmower. His eye is open and bleeding, he is screaming, and he just ate a McDonalds Happy Meal 30 minutes earlier. How will you anesthetize him for his eye surgery?” This open eye-full stomach case was a classic anesthetic exam question meant to make an examinee squirm. The child has no intravenous (IV) line yet, and because he is scared and in pain he won’t let you start an IV, so the option of an IV induction of general anesthesia is not available. Doing an inhalation induction of general anesthesia by mask is contraindicated because the child has a full stomach and is at risk of vomiting his cheeseburger into his airway. I’d read a lot from my anesthesia textbooks at that point, and I passed their exam. Then I was invited to the last step of their vetting process, which was the performance of 20 anesthetics during one week at their hospital while they observed and evaluated my skills.

This is where the story gets more interesting, because I was not a fully trained anesthesiologist yet. It was March of my second year of residency. I had only completed 20 months of the total program, and I still had 3½ months of education remaining. I shared this fact with their group, and also told them I hadn’t yet completed my month of pediatric anesthesia training, which was scheduled for June. I’d performed approximately 20 pediatric anesthetics during other rotations, but I was relatively inexperienced anesthetizing children. This was pertinent, because this Southern California anesthesia group staffed a nearby children’s hospital. I was reassured my incomplete pediatric training to date would not be a problem. “Don’t worry,” they said. “We’ll be in the operating room with you.”

“What about malpractice insurance?” I asked, knowing my malpractice insurance in my residency only covered me at my training sites near Stanford.

“You’ll have to get your own malpractice insurance,” they said. “You can’t go bare.”

I made a few phone calls, and one of the two main malpractice insurance companies in California agreed to insure me, even though I was still not yet board-eligible in anesthesiology.

We scheduled my tryout to occur during a vacation I had pending in late March. I drove to Southern California to begin my tryout. Was I nervous? Very much so. I arrived at their hospital on a Monday morning. I’d prepared my strategy for the week. I decided to stick with a common anesthetic regimen I’d used frequently at Stanford: IV Versed, followed by IV pentothal, fentanyl, and vecuronium for induction, followed by oxygen, isoflurane, and nitrous oxide for maintenance anesthesia for all general anesthesia cases. Propofol was not yet available, nor were sevoflurane, rocuronium, or laryngeal mask airways.

The first four days of the week flew by. My anesthetic recipe worked fine, and by my own assessment I was passing with flying colors. The group introduced me to the dollars and cents of anesthesia billing and business practice. In residency you learn nothing about the economics of private practice. I was handed a tablet of blank anesthesia bills to fill out for each case. The group’s arrangement with me was that I was to keep all the income I earned for performing those 20 cases. The attendings in this private anesthesia group explained the concept of “anesthesia units” to me. Each scheduled anesthetic had a startup value from 3 to 20 anesthesia units, depending on how complex the surgery was. For example, a finger surgery earned 3 startup units and coronary bypass surgery earned 20 startup units. Each 15 minutes of anesthesia time earned one additional unit. On day #1 I administered a spinal anesthetic for a woman having a Cesarean section. The startup unit value for the Cesarean section was 7 units, and the anesthetic time was 90 minutes (6 units), for a total bill of 13 units.

“How much is a unit worth?” I asked.

“Whatever the payor pays you,” I was told. “For a fully insured patient we bill $38 a unit, so you’ll get paid $494 for this case. For a Medi-Cal patient, you’ll collect about 1/5 of that fee.”

I was shocked. Four hundred ninety-four dollars was my approximate salary for a week as a resident. The earning potential of an anesthesiologist became apparent to me, and my enthusiasm grew. All I had to do was finish impressing my potential employers during these 20 cases and I’d have a strong chance of securing a high-paying job.

On Thursday night my dreamworld darkened. My first scheduled patient on Friday morning was a premature baby scheduled for an exploratory abdominal surgery. The patient was in the Neonatal Intensive Care Unit (NICU) on a breathing tube and a ventilator, with IVs in her left foot and right hand. The infant was born one week earlier, at a gestation of 34 weeks, i.e. 6 weeks premature. The infant weighed 2 kilograms, or about 4.4 pounds. When I saw the patient in the NICU Thursday evening, I knew I was in over my head. I’d never worked on a patient this tiny, and I wasn’t sure how to manage the anesthetic. I tried to telephone one of my pediatric anesthesia attendings at Stanford for advice, but I couldn’t reach him. The sun went down and my anxiety escalated. My primary concern was no longer whether I’d get the job, but rather whether I was safe to anesthetize this kitten-sized patient in the morning.

I didn’t sleep a minute all night.

Prior to the surgery the next morning, I walked up to the chief of the anesthesia group and told him the truth: Because I’d yet to do my month of pediatric anesthesia training, I was not comfortable doing this neonatal anesthetic. He received my remarks with a stern face, and told me someone else would do the case. I finished out that day doing easy adult orthopedic surgery cases, but I felt like a failure. The week finished, I turned in my billing records to the administrators in their main office, and drove back to Northern California. I knew I’d done the right thing—I knew I had no business doing that 34-week-old baby’s anesthetic with my incomplete training, but I felt badly.

One week later I received a letter from the private practice group which read, “We believe you would fit in best at some other practice than ours. Thank you for your interest in working for us.”

I crumpled the letter into a ball and tossed it in the garbage. My next problem surfaced the following day when I received a bill from the malpractice insurance company. This posed a dilemma. Did I need that private practice insurance anymore? The private practice malpractice policy was for “claims made,” meaning this policy had to be valid when a malpractice claim was made, not when the actual anesthetic was done. Should I keep paying for this insurance coverage in case one of those 20 patients in Southern California sued me in the next year? My anxiety returned, and I felt I had no one to ask for advice regarding this odd set of circumstances. Cancelling the malpractice policy meant accepting the risk of being sued without coverage. I thought back to my 20 cases, and found it difficult to image anything had gone wrong enough to run the risk of a malpractice lawsuit. I rolled the dice, and tore up the bill. I’d go bare and gamble that no lawsuit was pending.

Three months later I received another envelope from the Southern California anesthesia group. This one contained a check for what they’d collected from my 20 anesthetics. The sum was equal to 5 months of my Stanford resident salary. This was a happy coda to an emotional rollercoaster.

In June I completed my month of pediatric anesthesia training at Oakland Children’s Hospital, and gained the experience and skills I didn’t have in my Southern California tryout.

Could this drama happen today? No, for several reasons. It’s difficult to imagine any hospital or surgery center would grant temporary medical staff privileges to someone who had not finished their training. At the surgery center in Palo Alto where I’m Medical Director, candidates for medical staff membership and clinical privileges must not only be board-eligible, but they must also be board-certified in their specialty. And it’s unlikely a 21stCentury malpractice insurer would issue coverage for an anesthesia practitioner who was incompletely trained. And in present times most anesthesiologists covering neonatal anesthesia in a children’s hospital will have completed not just their residency, but also a subspecialty fellowship in pediatric anesthesia. Beginning in 1989, anesthesia residencies in the United States were expanded from two years to three years (post-internship).  At the 20th month mark in residency, when I was performing my “private practice tryout,” current anesthesia trainees would be barely half-finished with their 36-month residency.

Retelling this tale still makes me shake my head in disbelief. It was an anesthesia story—an anesthesia story like no other.

14 DIFFERENCES BETWEEN EXPERIENCED AND INEXPERIENCED ANESTHESIOLOGISTS

THE ANESTHESIA CONSULTANT

Is your doctor an experienced anesthesia provider or a newbie? The list below chronicles the crescendo of growth of as I’ve witnessed it from a newly-trained anesthesia doctor to an expert practitioner. It’s a development of skills, maturity, and judgment over many years. As a patient, the only signs you’re likely to recognize are #1 and #2 below, but each of these differences are real. In my view, inexperienced anesthesia providers are more likely to:

  1. Be nervous/anxious. This observation is no surprise. Everyone is more nervous at their job when they’re a novice than when they’re experienced. Imagine you’re two months out of anesthesia training, working at a community hospital, and at 2 a.m. you need to induce emergency anesthesia for a 300-pound man who just ate a full meal of pizza and beer two hours earlier. You’re working alone without that anesthesia attending who stood next to you during residency training. Anesthesia emergencies are anxiety-producing for both experienced and inexperienced anesthesiologists, but experienced doctors are more likely to know exactly what to do and what not to do. In this example, it’s a solid idea to get another anesthesiologist, or the emergency room MD if no anesthesiologist is available, to assist in the induction and intubation of this morbidly obese patient with a full stomach.
  2. Pay less attention to a patient’s preoperative medical comorbidities. Anesthesiology can be thought of as a subspecialty of internal medicine or pediatrics. At Stanford we’re the Department of Anesthesiology, Perioperative and Pain Medicine. “Perioperative” means “the time around an operation”—specifically the preoperative, postoperative, and intraoperative times. Inexperienced anesthesiologists may only contemplate a recipe of anesthesia drugs, instead of seeing his or her role as the management of the patient’s medical problems prior to, during, and after surgery. The sophisticated anesthesiologist must understand the patient’s heart disease, lung disease, kidney disease, etc., in the context of what the surgery and the anesthetic medications do to these diseases.
  3. Be prone to panic in emergencies and not follow the ABCs of Airway-Breathing-Circulation. When I review charts regarding medical malpractice during emergencies, too often I see anesthesia providers administering cardiac drugs and worrying about the blood pressure when no one has managed the airway (i.e. intubated the trachea), or no one is ventilating the patient. If your case turns into an unplanned emergency complication, always turn to the ABCs to guide your next moves.
  4. Use multiple intravenous anesthetic infusions for a routine case. When questioning an anesthesia resident, it’s not uncommon to hear an anesthetic plan which includes two intravenous infusions, one of propofol, and one of remifentanil. In my medical-legal work I review anesthesia charts from across the United States, and I can attest that by far the most common general anesthetic is a dose of propofol followed by sevoflurane (inhaled) maintenance. Sevoflurane is easy to use—you turn the vaporizer on at the beginning of the case and off at the end of the case—and we can accurately monitor the amount of sevoflurane going into and coming out of the lungs with our gas monitors. Using two IV infusions requires assembling the two sets of syringes and tubing, inserting two syringes into two syringe pumps, and programming the pumps. Failing to refill the infusions, or failing to turn them on, or any failure of the IV line can cause serious problems. Dual IV infusions defy the wisdom of the KISS Principle, i.e. Keep It Simple Stupid. And there are no data that remifentanil is a superior anesthetic to sevoflurane for most cases.
  5. Use recipes that include excessive narcotics. When administering mock oral exams to anesthesia residents, it’s common to hear that 250 micrograms of fentanyl are administered IV prior to anesthesia induction, to “blunt the hypertension from intubating the trachea.” In private community practice one discovers that as little as 50 micrograms of fentanyl is sufficient prior to anesthesia induction to blunt hypertension, and that by minimizing the total dose of narcotic for the case, one can achieve less post-intubation hypotension, a quicker wake-up at the conclusion of anesthesia, and less nausea that when one administers excessive narcotic. As a rule of thumb, try to administer a dose of narcotic 45 to 60 minutes prior to emergence to cover post-anesthetic pain requirements. Excessive doses prior to that time add to oversedation and excessive nausea without any clear benefit.
  6. Be afraid of surgeon criticism and feel on unequal status with the surgeon. As one of my faculty members told me decades ago, “some surgeons are bullies.” A bullying surgeon can often smell blood in the water when an anesthesia provider doesn’t feel assertive or confident. Your surgical colleague is skilled at surgery, but you are the expert at anesthesiology. It’s a symbiotic relationship. He or she needs you as much as you need the surgeon. Be confident in your decisions and in your conversation. The surgeon is not “the captain of the ship” in the operating room. You are both co-captains. In private practice, surgeons respect anesthesiologists, and vice versa.
  7. Administer multiple doses of paralytic drugs, so that a patient doesn’t ever move, which would upset the surgeon. See #5 above. If you’re afraid of a surgeon’s criticism, then an episode in which the anesthetized patient moves or coughs may seem like a minor catastrophe. It’s not. A reasonable reply when a patient moves is, “I’ll deepen the anesthesia. Everything’s OK. The patient is asleep.” Inexperienced anesthesia providers may attempt to keep patients paralyzed with muscle relaxant drugs such as rocuronium, even if paralysis isn’t necessary for a particular surgery (e.g. a limb surgery or a facelift), so the patient can’t move and the surgeon will have less opportunity to express anger.
  8. Draw up ten (unused) syringes prior to a routine anesthetic. Prior to the first case of the day, trainees often draw up multiple drugs into syringes, and then label the syringes, for every drug they could possibly use during that day. Syringes of atropine, ephedrine, phenylephrine, lidocaine, Zofran, fentanyl, Dilaudid and succinylcholine are lined up in a beautiful parallel array on the anesthesia machine desktop. Experienced anesthesiologists know that while it’s necessary to draw up two or three syringes of drugs such as propofol, fentanyl, and rocuronium, the other drugs are available in the top drawer of the anesthesia cart as needed. Some cases require no more than three drugs total. Some cases require a dozen drugs or more. Experienced anesthesiologists draw up drugs and narcotics when they are needed, not prophylactically.
  9. Believe every orthopedic patient needs an ultrasound-guided nerve block. Until the 21st Century, non-total-joint orthopedic cases on shoulders, elbows, hands, knees, and feet were routinely done without ultrasound-guided nerve blocks, and patients had few bad outcomes. Acute pain was treated with IV narcotics followed by oral pain relievers, and patients were discharged home in stable condition. Ultrasound-guided nerve blocks have a role in anesthesia care for orthopedic surgery, but they’re not mandatory. There are no data that ultrasound-guided nerve blocks improve long-term outcome, and the use of ultrasound has not decreased the small but non-zero incidence of permanent nerve damage. Experienced anesthesiologists consider nerve blocks as optional adjuncts for certain painful cases in certain patients. The “recipe” for orthopedic anesthesia does not have to include an ultrasound-guided nerve block.
  10. Fail to respect/fear a difficult airway for what it is: a potentially life-changing event for both the patient and you. One of the greatest risks you’ll face as an anesthesia provider is a patient with a difficult airway. If you mismanage or lose the airway, you run the risk of the patient having hypoxic brain damage after as little as five minutes without oxygen. A patient outcome of hypoxic brain damage can change your emotions and your life in painful ways. It’s not enough to learn the American Society of Anesthesiologists Difficult Airway Algorithm.  If you have a difficult airway, get help such as an additional anesthesiologist in the room. Use technology, such as a video laryngoscope and the difficult airway cart. If you lose the airway, be ready to perform a cricothyroidotomy if intubation or an LMA rescue are unsuccessful. A cricothyroidotomy is not that difficult https://theanesthesiaconsultant.com/2018/11/07/front-of-neck-access/ , and it can save a life—a better choice than waiting for a (non-ENT) surgeon to perform anterior neck access such as a tracheostomy.
  11. Treat bradycardia with Robinul instead of atropine. When a significant bradycardia occurs, i.e. a heart rate less than 50, or a heart rate less than 60 along with hypotension, the Advanced Cardiac Life Support (ACLS) treatment is atropine, not Robinul. Robinul, or glycopyrrolate, is an anticholinergic drug used almost exclusively by anesthesiologists. It’s a weaker chronotrope than atropine. When you want to accelerate the heart rate in the operating room or the post anesthesia care unit, use the first drug recommended in the ACLS and American Heart Association bradycardia algorithms—and that drug is atropine. If the patient has an adverse outcome after a symptomatic bradycardia episode and you didn’t administer atropine, you’ll have a difficult time defending your decision.
  12. Fail to write detailed postoperative notes after a complication occurs. Every anesthesia provider will eventually have complications. Your first responsibility is to manage the clinical circumstances as well as possible. Your second responsibility is to transfer the patient to the clinical forum that’s indicated after the complication, which may be an intensive care unit, a cardiology consult, or a transfer from a freestanding ambulatory surgical care unit to a hospital. Your third responsibility is to write a detailed note about what happened. Usually there’s no time to fill out the anesthesia record during an acute complication, but as soon as you have time, write a detailed note that describes the clinical circumstances that occurred, how you treated those circumstances, and what the patient’s response was. Your note should record the timeline, the vital signs the patient had, and what your presumed diagnosis was. Do this while your memory is fresh. This postoperative note is more than a clinical narrative, it’s a medical-legal document. Walking away from the case without writing a detailed postoperative note/summary is a mistake.
  13. Perform slow patient wakeups, and a slow turnover of cases. Private practice surgeons are faster than academic surgeons, because they are already fully trained and they’re not teaching anyone. A list of private cases will flow faster than a similar list in a university setting. Inexperienced anesthesiologists who haven’t learned how to wake patients efficiently will slow down the system. Inexperienced anesthesiologists can cause slow turnovers from one case to the next. In a private practice setting the operating room may be ready to accept the next patient in just 10 – 15 minutes. There’s little time for a trip to the cafeteria or to run errands.
  14. Fail to ask senior anesthesiologists in the group they just joined for advice on how to do a specific case. Faculty members in residency and fellowship are highly trained experts who guide trainees through academic surgical practice. Community private practice is not a training program—everyone is fully trained—and everyone aims for efficient, repeatable medical care. When you enter into this new arena, don’t be afraid to ask senior anesthesiologists for advice. They won’t be annoyed—they want you to succeed. It’s in everyone’s best interest for you to become a safe, efficient anesthesiologist as soon as possible. Before cases, feel free to ask a senior anesthesiologist how he or she does the anesthetic for an acute hip fracture in a 90-year-old. Feel free to ask how he or she does the anesthetic for a 6-hour revision open rhinoplasty. One day in the future you’ll be that senior anesthesiologist, experienced and ready to answer questions yourself.

HOW DOES EXECUTION BY NITROGEN GAS WORK?

THE ANESTHESIA CONSULTANT

The state of Alabama executed inmate Kenneth Smith on January 25, 2024, by forcing him to breathe 100% nitrogen gas. It was the first known execution in the United States by this method.

Smith was 58 years old. He was sentenced to death for his role in a 1988 murder. Smith’s lawyers had expressed that death by inhaling nitrogen would cause excessive pain and would be a form of torture. Appeals failed, and the execution went forward.

The procedure occurred at the William C. Holman Correctional Facility in Atmore, Alabama. Smith was fitted with a mask, and that mask was connected to a device that administered the nitrogen gas. The execution process began at 7:53 p.m., and Smith was pronounced dead at 8:25 p.m., thirty-two minutes later.

Thirty-two minutes? Not a swift execution.

How would nitrogen gas kill a person? The air we’re all breathing at this moment contains 21% oxygen and 78% nitrogen. The oxygen is essential for us to stay alive and well. Nitrogen serves no role in our normal breathing. If we breathe an atmosphere of less than 21% oxygen, we’re in danger of dying from inadequate oxygen to our brain and heart. A low amount of oxygen in the blood is termed “hypoxia.” Hypoxia is an extreme danger to life. During general anesthetics, anesthesiologists commonly administer a concentration of 50% oxygen to assure a margin of safety if there is difficulty with a patient’s airway, breathing, or circulation. The extra margin of oxygen is a safety net. No anesthesiologist would ever administer less than 21% oxygen to a patient.

Entering the search term “death by nitrogen gas” into the medical search engine PubMed yields just one article relevant to this execution. The article is “Case report of suicide by inhalation of nitrogen gas.”  The article states: “Nitrogen is an inert gas that is a normal constituent of the air that we breathe. It is a suffocating gas that does not support life and that can be a cause of death by the displacement of oxygen in the atmosphere. The majority of deaths associated with nitrogen have occurred in the setting of scuba diving. Although other suffocating gases have been used as a means of committing suicide, the literature contains little information about the use of nitrogen as a suicidal agent. A case of a 50-year-old man who committed suicide using a homemade suicide device and nitrogen gas is presented.”

There seems to be no published medical research on the method of death used to execute Kenneth Smith. And why would there be? Doctors are in the business of saving lives, not ending them.

If you and I were observers, what would the death of a person dying by nitrogen gas look like? A lack of oxygen would be the theme that describes this form of death. In a way, the individual would be drowning in an oxygen-free environment. It would be somewhat like drowning in water, an equally oxygen-free environment. The individual would begin by gasping for breath, hoping to find some oxygen somewhere in the inhaled gas. As the oxygen level in the individual’s bloodstream and brain plummeted, there would be symptoms of confusion, panic, and decreased consciousness. As the oxygen level in the individual’s bloodstream and heart plummeted, there would be rapid heart rate, rapid breathing, and eventually angina pain and a failure of the heart to pump anymore. Would this process be fast? No, a physician would predict this entire descent into an oxygen-free state to last ten minutes or more. Would it be like torture? Yes, in all likelihood it would be like torture.

We’re all going to die someday. This is not a method of death you’d desire or request.

Per the CNN coverage of Kenneth Smith’s execution: “Nitrogen flowed for about 15 minutes during the procedure, state corrections commissioner John Hamm said in a news conference. Smith, who was on a gurney, appeared conscious for ‘several minutes into the execution,’ and ‘shook and writhed’ for about two minutes after that . . . That was followed by several minutes of deep breathing before his breath began slowing ‘until it was no longer perceptible for media witnesses.’ . . . Smith appeared to be holding his breath ‘for as long as he could’ and may have also ‘struggled against his restraints. There was some involuntary movement and some agonal breathing, so that was all expected and is in the side effects that we’ve seen and researched on nitrogen hypoxia,’ Hamm said. ‘So nothing was out of the ordinary of what we were expecting.’”

Also per CNN: “Smith’s spiritual adviser, the Rev. Jeff Hood, witnessed the execution and described it in more graphic terms, saying it was ‘the most horrible thing I’ve ever seen.’”

In contrast to execution by breathing nitrogen, execution by lethal injection is essentially an anesthetic overdose which intends to kill a convicted inmate quickly. If correctly administered, there should be no pain or torture. A key problem with execution by lethal injection is that most MDs want no part of killing someone. Because of this value, who is going to start the IV? Who is going to prescribe the fatal intravenous recipe? Who is going to administer the fatal intravenous recipe?

Executing prisoners isn’t within the scope of medical doctors.

And let’s hope that this method of executing prisoners by having them breathe nitrogen gas is “a one and done” event.

SO YOU WANT TO BE AN ANESTHESIOLOGIST? TEN TRAITS OF ANESTHESIOLOGISTS

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Anesthesiologists aren’t well known to most patients, but these specialty doctors have certain traits in common. Anesthesiologists are likely to have:

  1. A preference for being in an operating room rather than in a clinic. The practice of anesthesiology is the practice of perioperative medicine. Perioperative medicine has three phases: prior to surgery, during surgery, and after surgery. While the preoperative process may involve a preoperative clinic in university settings, in most community practices the anesthesiologist evaluates the patient immediately prior to surgery. This may occur via a telephone call one day prior to surgery, or in the preanesthetic room on the day of surgery. Most of the time an anesthesiologist works in the operating room. Surgeons, by contrast, spend half their workdays in a clinic, seeing new patients who may need surgery or seeing post-operative patients in the days or weeks after surgery. A busy surgeon may work in the operating room two or three days per week. A busy anesthesiologist will be in the operating room five or more days per week.
  2. An affinity for inserting tubes and needles into patients. It may sound barbaric, but the practice of anesthesia requires at least one needle placement (an intravenous line) through which anesthetics are injected into the patient’s bloodstream, and usually one airway tube (an endotracheal tube or a laryngeal mask airway) into the patients upper airway through the mouth. Other common anesthesia procedures include the placement of catheters into the radial artery at a patient’s wrist, placement of a central venous catheter into a patient’s internal jugular vein at the neck, placement of spinal or epidural needles into a patient’s back, placement of ultrasound-guided regional nerve block needles adjacent to major nerves in a patient’s body, nasogastric tubes through the nose into a patient’s stomach, transesophageal echocardiogram probe into a patient’s mouth into the esophagus, and the placement of temperature probes into a patient’s nose or esophagus. By contrast, a typical internal medicine or pediatric physician who works in an office will do few procedures at all.
  3. A surgical personality, i.e. the desire to fix things now. One thing surgeons and anesthesiologists have in common is the desire to fix things as soon as possible. If a patient has appendicitis or a broken hip, in all likelihood the surgeon will schedule the surgery for that day, and the anesthesiologist will be there to render the patient free of pain. The pace of care in office medicine is slower. It may take days or weeks to make a diagnosis, and the prescription to remedy the problem may very well take days or weeks to treat the condition. Clinic medicine requires patience. Operating room medicine requires action.
  4. An adrenaline-seeking personality. The operating room is a charged setting. Within minutes there is a loss of consciousness by the patient, a surgeon making an incision, a surgical treatment, the sewing up of the patient’s wounds, and a reawakening back to consciousness. Most of the time there are no complications, but complications can occur. When things go wrong, the anesthesiologist and the surgeon need to respond quickly. For the anesthesiologist, if the airway or breathing to the patient is impaired for even five minutes, permanent brain damage can occur. There is no time for mistakes in diagnosis, mistakes in judgment, or mistakes in treatment. It’s often said that anesthesiology is 99% boredom and 1% panic. Anesthesiologists are effective during that 1% of time. They have to be.
  5. A disinclination to stand in one place all day. This relates to the difference between a surgeon’s work and an anesthesiologist’s work in the operating room. Surgeons stand beside the operating room table. Anesthesiologists stand at times, but during the stable durations of the surgery they can sit. When I was a 24-year-old medical student, I was certain I wanted to be a surgeon. I changed my mind when I finally did my surgical rotations, which involved holding a retractor and standing next to the attending surgeon watching procedures that often lasted four or more hours. Standing in one place all day isn’t for everyone. It wasn’t for me.
  6. Limited interest in long term interaction/relationships with their patients. Anesthesiologists meet most of their patients minutes prior to the surgery, and never see them after the day of surgery. This is in contrast to my primary care internal medicine doctors and pediatricians, who often see their patients several times per year over decades of time. Internal medicine doctors and pediatricians get Christmas gifts from their patients. Anesthesiologists do not.
  7. Interest in prolonged periods of time off or vacation. Anesthesiologists can work fulltime, but many choose to take numerous weeks off per year. In an anesthesia practice, because you don’t follow the same patients week to week, you have the potential for time off without disrupting patient care. Your duty to your anesthesia group is to do your contracted percentage of the workload, including a percentage of the on-call nights and on-call weekends. If you desire to travel to all the continents of the world, you’ll have that opportunity in many anesthesia practices.
  8. An enjoyable time talking to a patient for ten minutes. In the preoperative meeting between the patient and the anesthesiologist, it’s our responsibility to learn all the pertinent medical details about the patient, to examine them, to review all relevant laboratory and scan results, and then to explain the anesthetic plan. It’s our job to discuss risks and alternatives to that anesthetic plan, and then to gain the patient’s informed consent to proceed. Once the medical review and consent are completed, I have ten minutes with that patient while I start the intravenous line, administer the initial antianxiety drug, and transport the patient’s gurney down the hallway to the operating room with the circulating nurse’s assistance. During these ten minutes an anesthesiologist can have all sorts of interesting conversations with the patient. I commonly learn where the patient grew up, what kind of work they do, how big their family is, what their hobbies are, if they have pets, and where they would like to go on vacation. It’s an enjoyable exchange, until I inject propofol into their IV and they become unconscious.
  9. A contemplative nature. During my first month of anesthesia residency training, I was in the operating room with an anesthesia faculty member caring for a surgical patient. Once we injected the sodium pentothal (propofol wasn’t available yet) and placed the endotracheal breathing tube, the nursing staff prepped and draped the patient, and the 6-hour proposed surgery began. It was a prolonged teaching case involving junior surgery residents doing much of the work. After 30 minutes of teaching, with 5 hours and 30 minutes remaining, my anesthesia attending sighed and said, “in anesthesiology, it helps if you have a contemplative nature.” In the years to come I learned what he meant. The 99% boredom 1% panic ratio means there can be a multitude of minutes of steady-state stability, in which little is changing in the anesthesia management. The anesthesiologist has ample time to ponder whatever is on his or her mind. This sort of workplace characteristic isn’t for everyone, but it’s a part of daily life for most anesthesiologists.
  10. A desire to be well paid for their time. Physicians earn more for doing procedures than they do sitting in an office talking to patients. The workday in the operating room is a series of hands-on procedures, and most anesthesiologists are better compensated per unit of time when compared to internal medicine doctors or pediatricians who are in clinics talking and listening. Is this fair? I believe so. I was an internal medicine doctor before I trained in anesthesiology. I had a lot of knowledge, but I was never put in a situation in which a patient could become brain dead in five minutes if I made a mistake. I believe the operating room practice of anesthesiology is a more demanding and dangerous specialty than office medicine.

“Write what you know” is perhaps the most repeated advice given to prospective authors. Physicians know medicine and are uniquely qualified to write medical fiction. The 23 to 27 years of education required of each medical doctor includes significant training in both reading and writing, and it’s impossible to compose credible medical fiction scenarios without authentic medical training. I cringe when I read or watch fictional medical scenes that are impossible or unbelievable, such as the multiple postulated brain transplants in Jordan Peele’s 2017 movie Get Out. Doctors spend significant amounts of time learning to write nonfiction essays or research studies for medical journals, but what skills are required to write medical fiction, as opposed to the skills required to write up a study for the New England Journal of Medicine?

Fiction tells a story, and if it’s to be widely read, that story has to be compelling, unique, and grab the attention of readers. The most successful physician author of fiction was Harvard’s Michael Crichton, author of Jurassic Park, The Andromeda Strain, and other bestsellers. Crichton’s plots were based on true science, and usually involved catastrophic danger to the lead characters, who would overcome this danger through their own ingenuity and courage. Successful medical fiction will include unforgettable characters such as Dr. Roy Basch, The Fish, Eat My Dust Eddie or The Fat Man from the 1978 classic novel The House of God by Samuel Shem. Successful medical fiction has to contain more than medical scenes. Readers want to connect with the characters, and need to see how those characters live outside of their medical careers. Writing each chapter as a scene which either delivers an emotional shift or reveals a new secret, is a helpful technique to keep a story moving forward, rather than retaining unnecessary chapters that don’t add anything to the narrative.

In addition to medical knowledge, plot, and intriguing characters, writing medical fiction requires another critical element that most physicians lack, and that element is time. Physicians are busy people. Most medical careers require more than 50 hours a week, with time spent seeing patients in clinics or hospitals, charting on electronic medical records, and researching medical information from the internet or online libraries. There simply isn’t much time for recreational fiction writing, even if an MD has a terrific story to tell. It’s said that there are no great books written—there are only great books rewritten. It takes months or years to complete the initial manuscript of a novel, and then it takes months and hundreds of hours to reread, edit, and revise that manuscript. I’ve written three novels—one took thirteen years to complete, one took two years, and one took nine years.

What’s the key ingredient to writing medical fiction? Like most things in life, the key ingredient is emotion. If you love to write, you’ll find time, energy, and passion to write. I support my physician colleagues putting pen to paper or fingers to a keyboard to compose that story you have within you. The following interview by Norm Goldman from GoodPleasures reveals some of the inspiration and elements that led me to write my latest novel, Call From the Jailhouse:

 

AN INTERVIEW WITH RICK NOVAK discussing CALL FROM THE JAILHOUSE 

Love, Law, and Lethal Anesthetics: Unveiling the Medical Thriller of the Year.

Bookpleasures.com welcomes as our guest, Rick Novak MD. Rick is a distinguished Stanford physician, holding board certifications in anesthesiology and internal medicine.

His expertise and dedication extend to his role as an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University.

Beyond academia, he serves as the Medical Director at the prestigious Waverley Surgery Center in Palo Alto, California, and is a valued member of the Associated Anesthesiologists Medical Group in the same region.

Rick is not only a distinguished medical professional but also an accomplished author. He has shared his talents with the literary world through several captivating novels, including The Doctor and Mr. Dylan, Doctor Vita, and his most recent literary endeavor, Call From the Jailhouse.

Norm Goldman: Welcome Rick to bookpleasures.com and thanks for taking part in our interview. Can you share specific instances or experiences from your medical career that directly inspired or informed the content of your book, Call from the Jail House?

Rick: Call from the Jail House is a romance, a story about relationships. The two main characters are busy professionals, a doctor and an attorney, who are recently divorced but still have feelings for each other. The divorce rate in physicians is high (24%). I’ve been divorced myself, and I’ve experienced the enormous swings in emotion a failed marriage imparts on every phase of your life. These emotions drive my Call from the Jail House characters into predicaments they could never have imagined when they said “I do” to each other.

The second experience that drives the plot of Call from the Jail House is that the intravenous anesthetic drugs I’ve administered in my career are potent and wonderful, but when stolen from a hospital, they can kill an individual in minutes, in a fashion that would revolt and fascinate readers.

Norm: Sam Vella’s character undergoes a significant transformation from a beleaguered anesthesiologist to an accused murder suspect. Can you elaborate on the process of developing multi-dimensional characters like Sam in your writing?

Rick: Sam’s dilemma is a common one in America today—he’s an honorable young physician saddled with Herculean debt, with no easy way to repay it. He lives in Silicon Valley amidst astounding wealth, and when presented with the temptation to tap into that level of wealth, he surprises himself by pondering deeds never condoned in the Hippocratic Oath.

Norm: Cicely Vella, Sam’s ex, grapples with her role as a defense attorney torn between professional instincts and personal emotions. How did you approach creating her character and portraying this internal conflict?

Rick: Cicely is an outstanding litigator who rarely loses. She’s become wealthy beyond her dreams. But again, the powerful emotions of being newly divorced have driven Cicely to make success her only love. Sitting on her metaphoric pile of cash, no amount of money is filling the emptiness she feels since she divorced Sam. How can she become whole again? In her mind, the possibility of saving Sam from a life in prison looms as both a gigantic career leap and a relationship mending opportunity.

Norm: The story delves into a high-stakes murder trial filled with desire, wealth, intrigue, and scandal. What challenges did you face while crafting the courtroom scenes, and how did you maintain the tension throughout?

Rick: The first time I was cross-examined by an opposing attorney when I was serving as an expert witness in a courtroom, I held my hands together on the table in front of me. I could feel the pulse in my wrist, and my heart rate was topping 180 beats per minute. Outwardly I maintained a calm countenance, but inwardly I felt fear and confrontation unlike anything I’d felt in an operating room. The courtroom is a battlefield where words are weapons. Attorneys are on their home court. Everyone else—defendants, witnesses, experts, jury members—are involved in this war of sentences. As my career as an expert witness progressed, I became more comfortable with managing inner demons in the courtroom, but I’m well aware of the peril of the unprepared individual on the witness stand. Writing the courtroom scenes was the easiest part of this novel. These scenes were like movies I’d imagined for years.

Norm: Scarlett is an enigmatic character in the novel. What motivated you to include her in the story, and how did you explore the intricacies of desire and temptation through her character?

Rick: Can a dynamite-looking sexy young woman control the men that surround her? Yes, definitely. Anyone who denies this fact has never met a woman with Scarlett’s skillset. I fell under the spells of beautiful women more than once in my life, and I find the power of a gorgeous female one of the most interesting forces on Earth. Helen of Troy owned a face that launched a thousand ships. Like Helen, Scarlett inspires passions that can drive a vulnerable man to his doom.

Norm: The novel is described as a must-read for legal thriller fans. What do you believe sets Call from the Jail Houseapart from other books in the genre, and what unique elements did you incorporate into your storytelling?

Rick: Call From the Jailhouse is a romance novel with elements of a noir legal thriller and a medical mystery. The novel culminates in courtroom drama based on true medical facts and possibilities that only an anesthesiologist with a knack for telling suspenseful stories could describe. I love the writing of John Grisham and Scott Turow, but neither of them could pen this story of medical crime.

Norm: The relationship between Sam and Cicely is central to the plot. How did you approach writing their interactions and exploring the dynamics of their complicated past?

Rick: I chose to begin the novel with Sam and Cicely already divorced. Their backstory is revealed piece by piece. I see both Sam and Cicely as good people, outstanding in their professions, but inexperienced and uneducated in the abilities necessary to solve marital conflicts. After Sam’s call from the jailhouse, they both begin to rekindle the attraction that originally brought them together. Can Cicely save him? Even if she could, would Sam be willing to give their relationship a second chance? You have to read the book to find out.

Norm: Sam’s downfall from the mainstream anesthesia field to administering ketamine in dental offices is an important moment in the story. What inspired this particular plot point, and how did it affect the overall narrative?

Rick: The reason for Sam’s downfall from mainstream anesthesia is held out as a secret until the trial. His eviction from hospital medicine is credible. Physicians make mistakes—some of them medical, some of them emotional. Either one can have dire consequences. Sam’s fall from grace was critical for several reasons: it led to his divorce, it led to him driving around in a Chevy Tahoe with a tacklebox full of anesthesia drugs, and it led to his inability to earn the money he needs to pay his educational debt. Enter Scarlett, and remarkably there’s a new pathway toward all his dreams coming true.

Norm: Where can our readers find out more about you and Call From the Jailhouse?

Rick: Ricknovak.com  reveals more about me and my writing. My second website, clicked on over 2.8 million readers, is called The Anesthesia Consultant —and it contains 300+ essays which aim to inform both laypeople and medical people on anesthesia topics.

Norm: What is next for Rick Novak MD?

Rick: Back to the operating room every week. Back to the courtroom several times a year. And back to my MacBook Pro, which tempts me to set fingertips to the keypad, bringing the next set of fictional characters to life in situations no one’s ever dreamed of.

Norm: As we wrap up our interview, can you offer any insights into your creative process while writing this novel, and what can readers expect from your next literary masterpiece?

Rick: I’m a busy guy. I work as an MD from Monday through Friday, and I’m a single parent to three sons. I ponder ideas and scenes for future fiction every day.  I’ll set those thoughts into print by and by.

Norm: Thanks once again and good luck with all of your endeavors.

Rick: Thanks for your time, Norm!

HIGH FLOW NASAL OXYGEN: AN ANESTHESIA GAME-CHANGER

THE ANESTHESIA CONSULTANT

At the 2023 American Society of Anesthesiologists meeting in San Francisco, I walked by a booth advertising High Flow Nasal Oxygen. The product was called Optiflow. I asked the representative to educate me. She began by opening a package containing an Optiflow nasal cannula, and she strapped it around my head and into my nostrils. Within one minute she started a flow of 40 liters per minute of humidified, warmed 100% oxygen into my nose. I felt a slight sensation of moving air, but because the flow was humidified and warm, I felt no caustic insult of gas blasting through my nose and upper airway. I was—in a word—flabbergasted. The capacity to deliver this much oxygen to a non-intubated patient is a marked advance in anesthesia care.

HFNO was originally used in neonatal and pediatric ICUs to oxygenate acute hypoxemic respiratory failure patients without utilizing an endotracheal tube. Its use expanded to adult ICUs. The ability to deliver 60 to 70 liters per minute of oxygen via the nose enabled physicians to delay or avoid intubating ICU patients with hypoxemia. HFNO is delivered via nasal prongs which are larger than conventional nasal cannula prongs, and at higher flow rates than are generally applied during conventional oxygen therapy. Inspired oxygen/air is heated to 37 °C, and is humidified to 100% relative humidity.

A typical nasal oxygen cannula is limited to supplying 6 liters per minute of oxygen, which is approximately equivalent to delivering 45% oxygen. Using a typical nasal oxygen cannula at a flow higher than 6 liters will cause a patient significant irritation and drying of the nasal mucosa.  By humidifying and heating the oxygen inflow, HFNO can deliver 100% oxygen at a flow rate of up to 60 liters per minute via heated tubing and wide-bore nasal prongs.

 

 

Optiflow Airvo 2 high-flow nasal oxygen device: (1) wire-heated circuit tubing; (2) hot plate-heated humidification chamber system; (3) nasal cannula; (4) oxygen inlet port; (5) sterile water supply.

 

One day after attending the ASA meeting in San Francisco, I heard an in-person lecture in Palo Alto, California by Professor Anil Patel from the Royal National Throat, Nose and Ear Hospital in London. Dr. Patel has been a pioneer in bringing HFNO/THRIVE from the ICU into the operating room. Dr. Patel is the author of a seminal THRIVE (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange ) study, in which he wrote that THRIVE “has the potential to transform the practice of anesthesia by changing the nature of securing a definitive airway in emergency and difficult intubations from a pressured stop–start process to a smooth and unhurried undertaking.

Patel’s landmark 2015 publication “Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE): a physiological method of increasing apnea time in patients with difficult airways” demonstrated that High Flow Nasal Oxygen (HFNO), or THRIVE, “combines the benefits of ‘classical’ apneic oxygenation with continuous positive airway pressure and gaseous exchange through flow-dependent dead space flushing. We extended the apnea times of 25 patients with difficult airways who were undergoing general anesthesia for hypopharyngeal or laryngotracheal surgery. This was achieved through continuous delivery of transnasal high-flow humidified oxygen, initially to provide pre-oxygenation, and continuing as post-oxygenation during intravenous induction of anesthesia and neuromuscular blockade until a definitive airway was secured. Apnea time commenced at administration of neuromuscular blockade and ended with commencement of jet ventilation, positive-pressure ventilation or recommencement of spontaneous ventilation. During this time, upper airway patency was maintained with jaw-thrust. Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) was used in 15 males and 10 females. Mean (SD [range]) age at treatment was 49 (15 [25–81]) years. The median (IQR [range]) Mallampati grade was 3 (2–3 [2–4]), and direct laryngoscopy grade was 3 (3–3 [2–4]). There were 12 obese patients and nine patients were stridulous. The median apnea time was 14 (9–19 [5–65]) minutes. No patient experienced arterial desaturation < 90%.(bold emphasis added by me.)

Figure 2 from this study shows the stability of O2 saturation during the prolonged apnea:

Figure 3 from this study shows the stability of end-tidal CO2 levels during the prolonged apnea, with an average rate of carbon dioxide rise of only 1.1 mm Hg per minute.

HFNO can generate a low level of positive pressure in the upper airway, directly proportional to the high gas flow delivered, probably improving oxygenation by PEEP (positive end-expiratory pressure). This PEEP effect improves alveolar recruitment, and might also improve gas exchange.

Widespread adoption of HFNO as routine therapy in the operating room is still lacking. The main textbook in our specialty, Miller’s Anesthesia, 9th Edition, describes the use of THRIVE for difficult intubations, but their coverage is limited to one paragraph in a chapter on Adult Airway Management, in a section describing Apneic Oxygenation, out of the 3112 pages in the publication.

Many clinicians are simply not aware the technology exists or that it is available.  I believe many smaller hospitals and outpatient facilities such as ambulatory surgery centers do not own the required equipment. The cost of using HFNO exceeds the cost of standard nasal cannulae, but  the cost is not prohibitive. One Optiflow oxygenation+humidification unit made by F & P Healthcare sells for about $1500. The disposable nasal tubing apparatus for one patient sells for about $35.

Important uses of HFNO in perioperative medicine will include : a) keeping a difficult airway patient oxygenated while the anesthesia provider is performing intubation or airway procedures; and b) keeping morbidly obese patients or patients with hypoxemic cardiopulmonary disease oxygenated for brief procedures without needing to place an endotracheal tube or a laryngeal mask airway (LMA).

Let’s look at two demonstrative examples:

High Flow Nasal Oxygen utilized during difficult intubation

 

  • A 53-year-old patient with a difficult airway presents for general anesthesia for bariatric surgery. The patient weighs 350 pounds, stands 5 feet 8 inches tall, and has a Body Mass Index of 53, classifying him as super morbidly obese. His airway exam shows a thick neck (circumference 42 cm, or 16.5 inches), a small mouth, a Mallampati 4 classification, and limited neck extension. You apply HFNO with 100% oxygen at 60 liters per minute, and continue this for 10 minutes prior to inducing anesthesia with propofol and rocuronium. Once the patient is unconscious, you attempt intubation with a Glidescope, and have difficulty visualizing the vocal cords. A colleague assists you by advancing an endotracheal tube threaded over a fiberoptic laryngoscope, while you hold the Glidescope in place. After 14 minutes of apnea time, your colleague is able to advance the fiberoptic scope into the trachea and slide the endotracheal tube past the vocal cords. During all this time the patient was apneic but remained well oxygenated with a saturation nadir of 97% because of the HFNO.
  • A 40-year-old patient presents for an upper GI endoscopy under intravenous sedation. The patient weighs 275 pounds and stands 5 feet 5 inches tall, for a BMI = 45. His airway exam is Mallampati 2. His abdomen is protuberant, and you’re concerned this morbidly obese patient will become hypoxemic under propofol sedation. You connect the patient to HFNO with 100% oxygen at 60 liters per minute for 5 minutes, and then position the patient in the lateral position, left side down. His oxygen saturation is 100%, and you begin a propofol infusion. The patient’s breathing becomes shallower as he loses consciousness, but his oxygen saturation remains 100% as the GI doctor inserts the endoscope into her mouth and completes the procedure. Once the gastroenterologist is finished, you turn off the propofol, the patient awakens, and you bring him to the Post Anesthesia Care Unit where he is stable until discharge.

Upper GI Endoscopy with Optiflow High Flow Nasal Oxygen

 

Currently the American Society of Anesthesiologists (ASA) Difficult Airway Algorithm states, “Recommend supplemental oxygen administration before initiating and throughout difficult airway management, including the extubation process.” There is no specific mention of High Flow Nasal Oxygen (HFNO) or Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE), but the most effective way to administer supplemental oxygen during difficult airway management, without interfering with efforts to manage the airway, is High Flow Nasal Oxygen (HFNO) or Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE).

I believe a statement that High Flow Nasal Oxygen (HFNO) or Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) is a standard of care in perioperative airway management is, in all likelihood, coming in the very near future. The benefit/risk ration of utilizing High Flow Nasal Oxygen (HFNO) or Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) is very high.

I’d suggest you contact a manufacturer of High Flow Nasal Oxygen (HFNO) equipment such as the Optiflow unit,  and look into obtaining this useful adjunct for your facilities.

Disclaimer: I have no financial ties to the manufacturers of Optiflow, nor do I have any financial incentive for recommending their product. I simply want safer care for patients everywhere.

CardioPulmonary Resuscitation in the Operating Room

 

The Stanford Emergency Manual has become an essential reference for anesthesiologists. The manual lists diagnostic and therapeutic steps to follow in 26 different emergency scenarios. When a Code Blue or a dire change in vital signs occurs in an operating room, the Manual directs the resuscitation team to the correct order of action at a time when minds are racing, thoughts have become jumbled, and near-perfect intervention is required.

The Stanford Emergency Manual is now available in a 4¼ X 5-inch pocket version, suitable for carrying in one’s briefcase or backpack as you move from one anesthetizing location to another. The Stanford Emergency Manual has been used in all Stanford Hospital anesthetizing locations since 2012, and Stanford has printed and shipped thousands of Manuals to institutions around the United States and the world. One can also order a laminated 8½ x 11½-inch version of the Manual to hang in each operating room. A printable version of the Stanford Emergency Manual is available online for free.

In addition to Advanced Cardiac Life Support (ACLS) algorithms, the Stanford Manual lists specific instructions on the management of:

  • Anaphylaxis
  • Bronchospasm
  • Delayed Emergence
  • Difficult Airway/Cricothyrotomy
  • Embolism – Pulmonary
  • Fire – Airway
  • Fire – Non-Airway
  • Hemorrhage
  • High Airway Pressure
  • High Spinal
  • Hypertension
  • Hypotension
  • Hypoxemia
  • Local Anesthesia Toxicity
  • Malignant Hyperthermia
  • Myocardial Ischemia
  • Oxygen Failure
  • Pneumothorax
  • Power Failure
  • Right Heart Failure
  • Transfusion Reaction
  • Trauma

Why implement an Emergency Manual?  Supported by published literature, the Stanford group cites these reasons on their webpage:

“Medical simulation studies show that integrating an emergency manual into the operating room results in better management during crises events.

  • Pilots and nuclear power plant operators use similar cognitive aids for emergencies and rare events.
  • During a crisis event, the stacks of relevant literature are rarely accessible.
  • Memory worsens under stress and distractions interrupt our planned actions.
  • Expertise requires significant repetitive practice, so none of us are experts in every emergency.”
The Emergency Manual was created by the same team which pioneered simulator training for anesthesiologists, headed by Stanford faculty members Drs. David Gaba, Steven Howard, and Sara Goldhaber-Fiebert. The term “cognitive aid” is an academic term referring to resources which help people to remember or apply relevant knowledge appropriately, but since “cognitive aid” is not a familiar term to most anesthesia professionals, the Stanford authors call the book an Emergency Manual, a term which has developed broad acceptance. The Stanford group published the academic article “Emergency Manual Uses During Actual Critical Events and Changes in Safety Culture From the Perspective of Anesthesia Residents: A Pilot Study” in 2016,  and “Clinical Uses and Impacts of Emergency Manuals During Perioperative Crises” in 2020. Both articles describe the successful implementation of the Emergency Manual. Both were published in the journal Anesthesia and Analgesia.

This example illustrates the utility of the Stanford Emergency Manual:

An anesthesiologist is working at a freestanding outpatient surgery center, and is scheduled to anesthetize a patient for an arthroscopic rotator cuff repair. Prior to the surgery, the anesthesiologist is performing an ultrasound-guided interscalene nerve block when the patient suddenly loses consciousness and then develops cardiovascular collapse following the injection of the local anesthetic bupivacaine. The attending anesthesiologist remembers that the treatment for Local Anesthesia Toxicity involves injecting Intralipid intravenously, but he/she doesn’t remember the dose. The patient is turning blue and lacks pulses.  

The anesthesiologist calls out to the circulating nurse to bring in the Code Blue cart, hands his pocket copy of the Stanford Emergency Manual to a second nurse, and tells her to turn to the page on Local Anesthetic Toxicity and read the treatment instructions out loud. The nurse does so, and begins reading from these following pages from the Manual:

 

The anesthesiologist calls for Intralipid stat, while the nurse reads each line from the Emergency Manual treatment. The anesthesiologist follows the algorithm, intubates the trachea, and begins ventilating 100% oxygen into the patient’s lungs. CPR is started because there are no palpable pulses. The anesthesiologist then begins administering doses of Intralipid per the Manual. The patient is stabilized and eventually survives without any adverse outcome.

At the Palo Alto multi-specialty surgery center where I am the Medical Director, one Manual is available for the operating rooms and a second Manual hangs on the Code Blue Cart. We  teach a Mock Code or a Malignant Hyperthermia drill every six months, and we rehearse the use of the Stanford Emergency Manual during each drill.

If the facilities you work at don’t have copies of the Stanford Emergency Manual, get yourself a Pocket Emergency Manual.

You won’t regret it.

REVIEW FROM THE SAN FRANCISCO BOOK REVIEW:

Call From the Jailhouse

By Rick Novak
Extasy Books,  331 pages, Format: eBook and paperback

Star Rating: 5 / 5

Author Rick Novak, MD, does an exquisite job of crafting a scenario in which a man is accused of murdering his lover and her husband and brings it all the way into a full jury trial. Call From the Jailhouse introduces readers to top defense attorney Cicely Vella. Cicely is a savage in the courtroom and is able to present to the jury all the reasons why they should acquit. Cicely’s marriage to an anesthesiologist named Sam Vella ended in divorce almost a year and a half ago, although there were certainly times when she missed him. When Sam calls Cicely from the county jail and tells her he is being accused of murder, Cicely knows she must defend him. Although their marriage didn’t work out, Cicely knows Sam didn’t kill anyone.

I loved the way the book was crafted. It starts with the phone call and then goes back in time six months to tell the readers about how Sam meets his married lover, Scarlett. The story is carefully told, with no important detail left out. As a San Francisco Bay Area native, I loved that I knew where so many of the referenced places were, including the Pacific Athletic Club (now The Bay Club), the Stanford Dish, and Kings Mountain Road. I admit that I looked up the Mahogany, where Sam meets Scarlett, and as I guessed, there was no such place listed. It seemed like it could have been modeled after the Rosewood Hotel in Menlo Park.

Call From the Jailhouse moves at the perfect pace. As Sam and Scarlett’s secret relationship starts to bloom, Sam finds himself falling in love with her even though she treats him like she owns him. So, how does Sam find himself accused of murder?

The last half of the book is dedicated to Cicely defending Sam in court. All evidence seems to lead to Sam, even though most of it is circumstantial. They say, write what you know, so Novak’s extensive knowledge in the medical field allows him to cleverly insert medical references, such as a medicine used to paralyze patients to allow doctors to insert a breathing tube. It’s details such as this that give the readers a full understanding of the events that take place in the book.

The court case is my favorite part of the book. This is also where there is a huge twist in the plot that gets uncovered. Cicely is a fantastic attorney who has integrity, grit, and grace all rolled into one small Black woman. Sam is a romantic at heart who finds himself in a black widow’s web. Call From the Jailhouse has fabulous characters, beautiful backdrops, and a plot that will pull you closer with every page.

OUR STAR RATING SYSTEM  5 stars: Reviewer considers the book to be something that everyone should read. Reviewer would definitely read it again.

CALL FROM THE JAILHOUSE excerpt:

Chapter One: The Call

Cicely Vella’s receptionist announced, “Ms. Vella, your ex-husband is on line one. He says he’s in jail. He wants to talk to you.”

There are mileposts in life—moments that alter the future in earthshattering ways. The sudden change can be terrific or tragic. Cicely used to think her defining moment was the end of her marriage, but instead her defining moment occurred when she picked up line one and said, “Sam, what’s going on?”

His voice came through pressured and loud, so robust she had to hold the phone six inches away from her ear. “There’s been some kind of mistake,” he said. “The police arrested me. I’m in trouble.”

Cicely was shocked. Sam had never called her since their divorce, and she’d never heard this tone in his voice. He’d always been cool, calm, and controlled, even in the most stressful times. Cicely couldn’t hide her alarm. “Arrested you for what?”

“Murder.”

Cicely almost dropped the phone. “Murder? You’ve got to be kidding. Where are you right now?”

“The San Mateo County Jail. I need a defense attorney. I need you. Please help me.”

Cicely pictured Sam Vella sitting alone in a jail cell, and her response surprised her. She leapt out of her chair, ready to go to him. “I’ll be there in twenty minutes,” she said. “And don’t answer any questions from anyone until I arrive. Got that?”

“I won’t. And thank you so much for doing this for me.”

“I haven’t done anything yet.” Cicely hung up the phone, feeling the room spinning around her. This wasn’t possible. Sam was a smart guy—an altruistic medical doctor who simply couldn’t kill anyone. He’d been a flawed husband, a man who never quite got used to his overachieving wife’s career eclipsing his, but he wasn’t wired to commit violent crime. Cicely grabbed her purse and car keys and headed for the door. A petite Black woman, Cicely wore a gray wool pantsuit and a Brooks Brothers white cotton shirt. Her androgynous attire was her statement that, in the male-dominated world of litigating attorneys, she had the power to match up with her masculine opponents. Her business—the world of defendants and their alleged misdeeds—was a grim reality of treachery, deceit, ruses, and lies. Cicely didn’t see her vocation as a quest for truth, but rather a competition in search of victory. It was her job to conjure deception. Her joy came from constructing any reasonable alternative to the allegations of the prosecution. Every new case was a puzzle with a yet undiscovered solution. Finding that solution was the most enjoyable pastime Cicely had ever discovered. The money was good, but she knew in her heart she might even have done it for free.

It was that fun.

As Cicely exited through the waiting room, her receptionist said, “I overheard your conversation with Sam. Are you going to defend him?”

“Hell, yes. What kind of defense attorney would I be if my ex-husband spent the rest of his life rotting in prison as a convicted murderer?”

“You’ll be center stage if you defend him.”

“I’ll be center stage whether I’m his lawyer or not. We share a last name. We share a past. I’m going to the jail. I don’t know when I’ll be back.” Cicely’s thoughts were in turmoil. Her divorce was fresh—only one year old. After five workaholic years as man and wife, she and Sam painted themselves into two distant corners—a sad California career-trumps-love divorce. She’d pulled the plug on their marriage and concentrated on climbing to the pinnacle of the legal world. Cicely had only seen Sam twice since the divorce, and each time she felt the same two opposing emotions―a strong attraction to his physical presence, and sadness that the man who had once been her best friend was a stranger to her now.

Cicely knew the drive from her office to the jail very well. She met most of her clients for the first time within those very walls. Minutes later she sat face-to-face with Sam in a windowless white-walled room. He wore an orange jumpsuit with the number 71427 scrolled across his chest. His hair was parted in the middle, lanky and wet, as if he’d just stepped out of a storm, and his gaze never left Cicely. Her heart raced to be sitting so close to him again. He looked as vulnerable as a lost puppy and as breathtaking as any man she had ever set eyes on. Cicely skipped any pleasantries and started with the obvious question, “Who are you accused of killing, Sam?”

He shook his head and dropped his stare toward the table separating them. Then his eyes flicked upward for a second, partially hidden below thick hooded brows, and he said, “It was this woman I was dating. They claim I killed her. And they claim I killed her husband, too.”

“Two murders? Good God.” Cicely exhaled mightily. “Tell me what happened, starting when you first met this-this woman.” Cicely balanced her pen over an 8.5 X 14-inch yellow legal pad and prepared to chronicle Sam’s story.

“Her name was Scarlett,” Sam said. “It all started one rainy January night last winter…”

CONTINUOUS FINGER-CUFF BLOOD PRESSURE MONITORING

EDWARDS CLEARSIGHT FINGER-CUFF BLOOD PRESSURE MONITOR

 

Picture this: prior to surgery you place a blood pressure cuff around the middle phalanx of your patient’s right middle finger, instead of a standard cuff on the upper arm, to measure blood pressure. Is this the future? After decades of watching intermittent readings from oscillometric (standard) blood pressure cuffs, will we be monitoring data from a continuous finger-cuff instead?

Perhaps.

A study in the September 2023 issue of Anesthesiology showed that continuous finger-cuff arterial pressure monitoring helped anesthesia professionals a) reduce hypotension during the 15 minutes following induction of general anesthesia, and b) reduce hypotension during the duration of noncardiac surgery, compared to traditional intermittent oscillometric arterial pressure monitoring.

The study was done in a single medical center, the University Medical Center Hamburg–Eppendorf in Hamburg, Germany. A total of 242 patients aged 45 and older who were scheduled for noncardiac surgery were randomized to continuous finger-cuff arterial pressure monitoring or to intermittent traditional oscillometric arterial pressure monitoring. The continuous finger-cuff arterial pressure monitor used was the ClearSight system manufactured by Edwards Lifesciences, USA.

Edwards ClearSight Monitoring System

 

An appropriately sized finger-cuff (small, medium, or large) was positioned on the middle phalanx of the third or fourth finger of every patient, along with a standard intermittent oscillometric arterial pressure monitor on the opposite arm. Traditional oscillometric arterial pressures were measured at 2.5 minute intervals. The clinical monitoring for each patient was randomized to be either 1) unblinded continuous finger-cuff arterial pressure monitoring, or 2) intermittent standard oscillometric arterial pressure monitoring with the finger-cuff data blinded. The Hamburg medical center’s institutional routine was to maintain MAP (mean arterial pressure) above 65 mmHg, and intraoperative hypotension was treated with intravenous norepinephrine, which was given at the discretion of each attending anesthesiologist.

The Anesthesiology study had two primary endpoints. The first was the amount of hypotension during the 15 minutes following the induction of anesthesia, and the second was the time-weighted average MAP less than 65 mmHg during the entire surgery. Results showed that continuous finger-cuff arterial pressure monitoring helped anesthesia providers a) reduce hypotension within the first 15 minutes after starting induction of anesthesia, and b) reduce hypotension during the entire noncardiac surgery. Patients assigned to continuous finger-cuff monitoring received more than twice as much norepinephrine both within 15 minutes after starting induction of anesthesia and during the entire surgery, when compared with patients assigned to intermittent oscillometric monitoring. This presumably explains why there was significantly less hypotension in the continuous finger-cuff monitoring group.

Intraoperative hypotension carries risks of major postoperative complications, including acute kidney injury, myocardial injury, and death. Previous studies have validated that both the severity and the duration of intraoperative hypotension are associated with postoperative complications and mortality.  Two previous trials validated the efficacy of continuous finger-cuff arterial pressure monitoring during surgery. In a study of 160 patients undergoing orthopedic surgery, continuous finger-cuff monitoring resulted in less than half the number of hypotensive events, defined as a MAP less than 60 mmHg (19 vs. 51 events).  A second study of 316 patients undergoing noncardiac surgery showed that continuous finger-cuff arterial pressure monitoring nearly halved the amount of intraoperative hypotension, defined as the time-weighted average MAP less than 65 mmHg.

The Edwards Lifesciences website describes the ClearSight continuous finger-cuff monitoring system.   In addition to continuous blood pressure monitoring, the ClearSight system records advanced hemodynamic parameters from the noninvasive finger cuff, including graphic trend displays on the Edwards Lifesciences HemoSphere monitor of:
• Cardiac output (CO)
• Stroke volume (SV)
• Stroke volume variation (SVV), and
• Systemic vascular resistance (SVR).

These parameters provide additional information which, if validated, can expand the information an anesthesia provider can monitor routinely. The parameters of continuous blood pressure (ART), continuous Mean Arterial Pressure (MAP), Cardiac output (CO) and Stroke volume (SV) are shown on the HemoSphere monitor below.


The technology behind the ClearSight continuous finger-cuff monitor involves a principle called the volume clamp method. Per the Edwards Lifesciences website, this “involves clamping the artery in the finger to a constant volume, by dynamically providing equal pressure on either side of the arterial wall. The volume is measured by a photo-plethysmograph built into the cuff. The counter pressure is applied by an inflatable bladder inside the cuff and is adjusted 1000 times per second to keep the arterial volume constant. Continuous recording of the cuff pressure results in real-time finger pressure waveform.

Volume clamp cross section

 

Interior of the Edwards finger-cuff

 

Dr. Daniel Sessler, one of the world’s most respected and prolific anesthesia researchers, is a co-author of the recent Anesthesiology study. To me this validates the notion that continuous finger-cuff technology may eventually gain widespread adoption in operating room monitoring. (Note also that Dr. Sessler is a consultant for Edwards Lifesciences, and has received research funding from the company, as have some of the other authors of the Anesthesiology study.)

Unanswered questions regarding continuous finger-cuff blood pressure monitoring include:

  • Would data show that more frequent utilization of oscillometric (standard) blood pressure readings, recordedwith our existing equipment every one minute instead of every 2.5 minutes, give as much information as a continuous finger-cuff?
  • If a patient’s hand or fingers are jiggled or moved during monitoring, would the continuous finger-cuff give significant artifacts?
  • Would clinicians use both traditional blood pressure cuff monitoring and continuous finger-cuff monitoring on the same patient, and make physiologic conclusions from both sources of input?
  • Will other models of finger-cuff monitoring, different from the Edwards Lifesciences ClearSight model, vary in accuracy? Will clinicians trust new finger-cuff monitoring devices and their data?
  • What will be the price of this technology?

The benefit/risk ratio of continuous finger-cuff monitoring appears to be high. The technology is noninvasive and unlikely to harm our patients in any way, as long as the data is accurate. The dollar cost of this new technology will influence its rate of adoption. Existing intermittent oscillometric (traditional) blood pressure monitoring devices are already present in every operating room as standard equipment on today’s budgets. If continuous finger-cuff blood pressure monitoring is both accurate and inexpensive, the new technology may be universally adopted. But because a majority of anesthetics are administered to reasonably healthy ASA 1 or ASA 2 patients, many of them in outpatient surgery centers, one could argue that measuring intermittent blood pressures every 2.5 to 3 minutes with oscillometric (traditional) blood pressure monitoring devices is an adequate monitoring interval for these patients. If the added cost of continuous finger-cuff monitoring is excessive, this technology may be limited to hospitals, where sicker patients are anesthetized for bigger and more invasive surgical procedures, and which present increased risk for patients with hypotension.

The Food and Drug Administration recently approved an additional monitoring system based on finger-cuff technology from Edwards Lifesciences, the Acumen Hypotension Prediction Index (HPI) software system. This system uses machine learning to alert clinicians of the likelihood a patient is trending toward hypotension, or low blood pressure.

Keep your eyes open for further studies on the ClearSight system, the Acumen system, and other continuous finger-cuff monitoring equipment. This technology may become part of our operating room life in the near future.

Litigator Cicely Vella’s ex-husband is arrested for a double murder, and asks her to be his defense lawyer. Cicely rarely loses a case, but her extraordinary record is in jeopardy when she chooses to defend Sam Vella, the only suspect in what appear to be two indefensible crimes.

Cicely is living the dream life of a young professional. She’s bright, beautiful, Black, and successful, but she harbors one weakness—lingering feelings for Sam, the husband who got away.

Samuel Vella is a physician with high intellect, striking good looks, and a proclivity for making poor decisions. In the aftermath of his split from Cicely, Sam initiates an affair with Scarlett Lang, a free-spirited married woman, and their liaison lands Sam behind bars.

After receiving Sam’s call from the jailhouse, Cicely feels the triple lures of her emotional attachment to her ex-husband, the opportunity to redeem the Vella name in the courtroom, and her zest for fame in this sensational high-profile trial. Nothing in the world but this court date could make Cicely and Sam sit elbow to elbow, day after day.

The odds of a divorced couple remarrying the same person are 6 in 100, a statistic Cicely is both aware of and wary of, as she’s drawn back into Sam’s life.

CALL FROM THE JAILHOUSE excerpt:

Chapter One: The Call

Cicely Vella’s receptionist announced, “Ms. Vella, your ex-husband is on line one. He says he’s in jail. He wants to talk to you.”

There are mileposts in life—moments that alter the future in earthshattering ways. The sudden change can be terrific or tragic. Cicely used to think her defining moment was the end of her marriage, but instead her defining moment occurred when she picked up line one and said, “Sam, what’s going on?”

His voice came through pressured and loud, so robust she had to hold the phone six inches away from her ear. “There’s been some kind of mistake,” he said. “The police arrested me. I’m in trouble.”

Cicely was shocked. Sam had never called her since their divorce, and she’d never heard this tone in his voice. He’d always been cool, calm, and controlled, even in the most stressful times. Cicely couldn’t hide her alarm. “Arrested you for what?”

“Murder.”

Cicely almost dropped the phone. “Murder? You’ve got to be kidding. Where are you right now?”

“The San Mateo County Jail. I need a defense attorney. I need you. Please help me.”

Cicely pictured Sam Vella sitting alone in a jail cell, and her response surprised her. She leapt out of her chair, ready to go to him. “I’ll be there in twenty minutes,” she said. “And don’t answer any questions from anyone until I arrive. Got that?”

“I won’t. And thank you so much for doing this for me.”

“I haven’t done anything yet.” Cicely hung up the phone, feeling the room spinning around her. This wasn’t possible. Sam was a smart guy—an altruistic medical doctor who simply couldn’t kill anyone. He’d been a flawed husband, a man who never quite got used to his overachieving wife’s career eclipsing his, but he wasn’t wired to commit violent crime. Cicely grabbed her purse and car keys and headed for the door. A petite Black woman, Cicely wore a gray wool pantsuit and a Brooks Brothers white cotton shirt. Her androgynous attire was her statement that, in the male-dominated world of litigating attorneys, she had the power to match up with her masculine opponents. Her business—the world of defendants and their alleged misdeeds—was a grim reality of treachery, deceit, ruses, and lies. Cicely didn’t see her vocation as a quest for truth, but rather a competition in search of victory. It was her job to conjure deception. Her joy came from constructing any reasonable alternative to the allegations of the prosecution. Every new case was a puzzle with a yet undiscovered solution. Finding that solution was the most enjoyable pastime Cicely had ever discovered. The money was good, but she knew in her heart she might even have done it for free.

It was that fun.

As Cicely exited through the waiting room, her receptionist said, “I overheard your conversation with Sam. Are you going to defend him?”

“Hell, yes. What kind of defense attorney would I be if my ex-husband spent the rest of his life rotting in prison as a convicted murderer?”

“You’ll be center stage if you defend him.”

“I’ll be center stage whether I’m his lawyer or not. We share a last name. We share a past. I’m going to the jail. I don’t know when I’ll be back.” Cicely’s thoughts were in turmoil.

Her divorce was fresh—only one year old. After five workaholic years as man and wife, she and Sam painted themselves into two distant corners—a sad California career-trumps-love divorce. She’d pulled the plug on their marriage and concentrated on climbing to the pinnacle of the legal world. Cicely had only seen Sam twice since the divorce, and each time she felt the same two opposing emotions―a strong attraction to his physical presence, and sadness that the man who had once been her best friend was a stranger to her now.

Cicely knew the drive from her office to the jail very well. She met most of her clients for the first time within those very walls. Minutes later she sat face-to-face with Sam in a windowless white-walled room. He wore an orange jumpsuit with the number 71427 scrolled across his chest. His hair was parted in the middle, lanky and wet, as if he’d just stepped out of a storm, and his gaze never left Cicely. Her heart raced to be sitting so close to him again. He looked as vulnerable as a lost puppy and as breathtaking as any man she had ever set eyes on. Cicely skipped any pleasantries and started with the obvious question, “Who are you accused of killing, Sam?”

He shook his head and dropped his stare toward the table separating them. Then his eyes flicked upward for a second, partially hidden below thick hooded brows, and he said, “It was this woman I was dating. They claim I killed her. And they claim I killed her husband, too.”

“Two murders? Good God.” Cicely exhaled mightily. “Tell me what happened, starting when you first met this-this woman.” Cicely balanced her pen over an 8.5 X 14-inch yellow legal pad and prepared to chronicle Sam’s story.

“Her name was Scarlett,” Sam said. “It all started one rainy January night last winter…”

THE ANESTHESIA CONSULTANT

Street use of the anesthetic ketamine is on the rise. Kylie, a 28-year-old professional female, recently told me about her experience snorting recreational ketamine: “I was feeling anxious and I was feeling sad. My friend suggested I try snorting some ketamine crystals she had, and when I did . . . I had the best feeling of my life. The drug made me happier. It made the next hour a fun experience without any sadness, and when the high wore off an hour later my sadness was still gone. It was as if I’d been treated with some antidepressant drug, and the improvement in my mood was more lasting than the initial buzz. Now I see my future using ketamine as a periodic antidepressant. When you read about it on the internet, doctors are prescribing ketamine as a treatment for depression, but the whole medical clinic intravenous treatment is really expensive. It’s a lot easier to do it myself with ketamine I buy on the streets.”

Hmmm. We’re all aware of the dangers of recreational drug use with cocaine or methamphetamine or narcotics. We’re all aware of the dangers of recreational drugs laced with fentanyl, a powerful drug that can stop a person’s breathing and kill them in minutes. In this context, what kind of a threat is street ketamine?

 

KETAMINE AS AN ANESTHETIC

Ketamine is a powerful general anesthetic drug in an anesthesiologist’s toolbox. In 1962 Calvin Stevens, a professor of chemistry at Wayne State University, synthesized ketamine from phencyclidine (PCP), an animal tranquilizer/anesthetic also known as angel dust, with the desired goal of discovering a safer anesthetic with fewer hallucinogenic effects than PCP.

Anesthesiologists administer ketamine intravenously to produce general anesthesia without utilizing any anesthesia gas. We call ketamine a dissociative drug, because it can distort sensory perception and impart a feeling of detachment from oneself and the environment. The drug can produce bizarre and unpleasant nightmares, so anesthesiologists are trained to pair ketamine with an intravenous benzodiazepine such as Versed to temper ketamine’s potentially frightening dream world. Anesthesiologists are also trained to pair ketamine with an anticholinergic (mouth-drying) medication such as atropine or glycopyrrolate (Robinul), because ketamine can produce excessive salivating, which can lead to a patient choking on a rising tide of saliva.

For anesthesia usage, ketamine is a clear liquid with a concentration of 100 mg/ml or 50 mg/ml.

Because ketamine is an effective general anesthetic in one syringe, it’s included on the World Health Organization’s list of essential drugs.  For medical sedation, ketamine is typically diluted and administered intravenously in small boluses of 20 to 30 mg, and titrated to obtain the desired depth of anesthesia.  To induce general anesthesia, the intravenous dose is 1 – 4.5 mg/kg, or a mean dose of 2 mg/kg = 100 mg for a 50 kg adult. If it’s not possible to insert an IV line (e.g. if a patient is uncooperative, developmentally delayed, or is a child), a combination of 2 mg/kg of ketamine, 0.2 mg/kg of midazolam, and .02 mg/kg of atropine can be administered as an intramuscular injection into the deltoid muscle of the shoulder or the quadriceps muscle of the anterior thigh. To induce general anesthesia with intramuscular ketamine alone, dosing levels are higher than for intravenous use, for example the intramuscular dose is 6.5 – 13 mg/kg, or a mean dose of 10 mg/kg = 500 mg ketamine for a 50 kilogram adult.

How does medical ketamine affect a patient’s ABCs of airway, breathing, and circulation? Patients typically maintain an adequate airway and breathing during ketamine sedation and anesthesia, which is advantageous in short surgical procedures because this often eliminates the need for a breathing tube. Ketamine causes stimulation of the cardiovascular system, with the potential side effect of increasing blood pressure.

There is no reversal agent for ketamine. If an administered ketamine dose is excessive, a patient’s airway and breathing may become compromised, resulting in inadequate oxygen delivery to the lungs, heart, and brain. Patients who are obese, or who have obstructive sleep apnea, may lose their safe airway and breathing status during ketamine sedation. Ketamine can elevate blood pressure, so vigilant monitoring of the blood pressure is required, and acute treatment for hypertension may be necessary. Because of these risks, ketamine administration is typically limited to anesthesia professionals or physicians who are experts in the emergency management of airways and acute vital sign changes.

 

KETAMINE AS AN INTRAVENOUS ANTIDEPRESSANT DRUG

Multiple meta-analyses have concluded that IV ketamine is an effective rapid-acting antidepressant for major depressive disorders.  Ketamine was first reported to have antidepressant properties in the year 2000, when published data showed that an intravenous administration of a sub-anesthetic ketamine dose resulted in a reduction of symptoms in major depressive disorder (MDD). MDD is a common disorder with significant consequences. A 2012 epidemiological study of mental health in Canada showed the lifetime prevalence of major depressive disorder was 3.9%. The prevalence was higher in women and in younger age groups. Ketamine is a treatment option for patients suffering from treatment-resistant depression (TRD). IV ketamine can exert rapid antidepressant effects as early as several hours after administration. In contrast, traditional oral antidepressant pills usually require several weeks of therapy for a clinical response. Ketamine has a unique mechanism of action on the central nervous system, at the NMDA (N-methyl-D-aspartate) and AMPA (𝛼-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptors, rather than at the serotonin and/or noradrenaline neurotransmitters that are the sites of action for traditional antidepressant pills such as Prozac, Paxil, or Zoloft.

Intravenous ketamine clinics are typically supervised by an attending anesthesiologist whose is present is to ensure the safe management of airway, breathing, and circulation during these brief sedation anesthetics. Intravenous ketamine administered in a clinic setting can result in adverse effects during the infusion period and immediately afterward, including nausea, vomiting, drowsiness, dizziness, confusion, dissociation, or an increase in blood pressure.Typically an infusion of 0.5 mg/kg of ketamine (e.g. 40 mg for an 80 kg patient) is administered slowly over 40 – 60 minutes. The patient will remain onsite in a recovery room until the sedative effects have cleared. Patients report positive antidepressant effects within two hours, and these effects last for one to two weeks. Data demonstrate a positive response rate of 44% after six intravenous ketamine treatments in patients with treatment-resistant depression.  A series of anesthetics will cost significantly more than one Prozac pill per day, so the use of ketamine as an antidepressant is directed at treatment-resistant depression.

 

KETAMINE AS AN INTRANASAL ANTIDEPRESSANT DRUG

In 2019 the FDA approved a nasal spray called Spravato (active ingredient esketamine) for major depression that failed treatment with two or more oral antidepressants.

Per the Spravato website:

SPRAVATO® is a non-competitive N-methyl D-aspartate (NMDA) receptor antagonist indicated, in conjunction with oral antidepressant, for the treatment of:  treatment-resistant depression in adults, depressive symptoms in adults with major depressive disorder (MDD) with acute suicidal ideation or behavior.

SPRAVATO® is intended for use only in a certified healthcare setting.

SPRAVATO® is intended for patient administration under the direct observation of a healthcare provider, and patients are required to be monitored by a healthcare provider for at least 2 hours. SPRAVATO® must never be dispensed directly to a patient for home use. 

 

 

The advantage of intranasal ketamine is that it does not require an IV, and it requires monitoring by a healthcare provider but does not require an anesthesiologist to supervise its administration.

 

KETAMINE AS A RECREATIONAL DRUG

To supply the illicit street market, diverted pharmaceutical liquid ketamine is evaporated from its liquid solution into a powdered form.

How popular is recreational ketamine? The number of ketamine seizures by federal, state and local law enforcement in the United States increased from 55 in 2017 to 247 in 2022. The total weight of ketamine confiscated increased by more than 1,000 percent over the five years. The majority of the confiscated ketamine was in powder form. According to the DEA (Drug Enforcement Agency), powdered ketamine is typically packaged in “small glass vials, small plastic bags, and capsules as well as paper, glassine, or aluminum foil folds. . . . powdered ketamine is cut into lines known as bumps and snorted, or it is smoked, typically in marijuana or tobacco cigarettes. . . . Ketamine is found by itself or often in combination with MDMA, amphetamine, methamphetamine, or cocaine. . . . Ketamine produces hallucinations. It distorts perceptions of sight and sound and makes the user feel disconnected and not in control. A ‘Special K’ trip is touted as better than that of LSD or PCP because its hallucinatory effects are relatively short in duration, lasting approximately 30 to 60 minutes as opposed to several hours. . . . An overdose can cause unconsciousness and dangerously slowed breathing.” (bold lettering mine.)

Recreational users call the phenomenon of a deep ketamine high as a “K-hole.” Falling into a K-hole means the drug user is temporarily unable to interact with others or the world around them. Some people refer to a K-hole as an out-of-body or near-death experience. The effects of long-term use of dissociative drugs such as ketamine haven’t been exhaustively studied, but ketamine use is thought to be reinforcing, meaning that individuals find the ketamine high an experience they wish to repeat. Repeated ketamine usage likely leads to some degree of tolerance and physical dependence.

The website The Cut states that “most of the recreational users . . . take K in very small doses, seeking a pleasant buzz that wears off within 30 minutes or can be re-upped as needed. It’s often taken to compliment other drugs — a garnish instead of the main course. For a generation that has less free time for sprawling multi-day psychedelic trips, ketamine has an appealing choose-your-own-adventure quality. . . . Claire says it actually feels like a healthier and more mature lifestyle. ‘People are like: I used to go out and have 16 drinks and do a bunch of cocaine and feel like shit the next day. And then it was this total shift [to ketamine]: Oh, yeah, I can do this. And it still feels like stepping out of my life, but I also feel fine tomorrow.’ At this point, she says: ‘I wouldn’t say that it’s different than like, a bunch of people getting off work and going out for drinks.’”

 

KETAMINE AS A RECREATIONAL ANTIDEPRESSANT?

Can a layperson use ketamine recreationally to treat themself for depression? The specter of self-treatment reminds one of the saying that a physician who treats himself has a fool for a doctor and a fool for a patient. A corollary of this is: a person who treats his or her mood disorder with recreational ketamine has a fool for a caretaker and a fool for a patient.

Kylie will attempt to titrate ketamine recreationally to treat her depression. But a precise, tailored medical dose is required for patients to experience optimal benefit from ketamine with safety. Individuals who self-administer ketamine expose themselves to serious health risks. Ketamine may make their symptoms worse, or they may even die from the habit. Kylie has no plans to have a healthcare provider present when she self-administers ketamine. Kylie has no idea of the milligram dose she is snorting. Her ketamine is not FDA-approved, and may in fact contain fentanyl at a dose that could cease her breathing and kill her.

How dangerous is ketamine? A meta-analysis of the published medical literature showed a total of 312 overdose cases and 138 deaths from recreational ketamine. There were no cases of overdose or death related to the use of ketamine as an antidepressant in a therapeutic setting. Street ketamine may seem cheaper, as the cost of ketamine on the street is approximately $100 per gram (1000 mg), and a single dose is approximately 100 mg. Medical treatment with 50 mg IV ketamine costs approximately $400-$800 per treatment. But ketamine administered by anesthesiologists in a clinic is safe, while there are legitimate respiratory and cardiac risks involved in the recreational use of ketamine.

If Kylie is depressed and seeks relief, an appropriate action would be to consult a psychiatrist. The alternative of intermittent recreational intranasal ketamine as a self-administered treatment for her depression is a dangerous detour.

THE ANESTHESIA CONSULTANT

This column will help you find the top 10 anesthesia journals. Prior to the internet, hard copies of medical journals were bound into volumes and stored at hospital or medical school libraries. To find a specific article required a dive into the archives of the library, with the eventual reward of finding the specific article and then photocopying it to use for your pending lecture, paper, or patient care. In the internet age, all journals are catalogued in the virtual library of the search engine PubMed.  Once you find your desired article, the abstract or sometimes the full text article is available for you to read and/or copy into your personal computer.

With this virtual library model, it makes little sense for individual clinicians to subscribe to monthly journals. Your search for journal references is done via Google or PubMed. Which journals are accessed most often? Traditional academic rankings of journals rely on the “impact factor” of each journal.

Impact factor is defined as the “scientometric index which reflects the yearly mean number of citations of the articles published in the last two years in that journal.” One such impact factor ranking list is located here.  The impact factor/rate of citations is different from the number of clicks an article receives on internet searches. How many people actually read an article? There is currently no ranking system to quantitate the important metric of internet clicks, which would document the degree of interest readers have with a specific article or journal.

Clinical anesthesia providers such as myself want to read information which impacts patient care, rather than to read basic science studies such as this one:  Pholcodine exposure increases the risk of perioperative anaphylaxis to neuromuscular blocking agents: the ALPHO case-control study. Which journals/publications contain the most valuable clinical information? There are multiple fine journals in our specialty, but in my opinion the top 10 periodical anesthesia publications for clinical information follow below. Note that 2 of the top 4 publications did not even exist when I began my anesthesia training in 1984.

THE 2023 ANESTHESIACONSULTANT.COM LIST OF THE TOP 10 ANESTHESIA PUBLICATIONS:

THE ANESTHESIA CONSULTANT

America is in the midst of a fentanyl crisis. There were 71,238 fentanyl overdose deaths in the United States in 2021. The Drug Enforcement Administration (DEA) states, “fentanyl is involved in more deaths of Americans under 50 than any cause of death, including heart disease, cancer, homicide, suicide and other accidents.”

Despite this, during surgery your anesthesiologist injected fentanyl into your IV as part of your anesthetic. Is that safe?

Yes.

As a street drug, fentanyl overdose is a critical problem in the United States, but anesthesiologists administer fentanyl to most patients, and do so safely. I review charts from all regions of the U.S., and virtually every anesthetic includes the safe use of fentanyl. Fentanyl was introduced in the 1960s when it was first patented under the brand name Sublimaze, and fentanyl quickly became the most commonly administered narcotic by anesthesia providers. In operating room anesthesia, the narcotic fentanyl is a clear liquid usually marketed in vials of two milliliters or five milliliters.

Why do anesthesiologists utilize fentanyl? Most surgeries cause pain, and our pharmaceutical options for relieving pain include local anesthetics, anesthesia gases,  or narcotics. When possible, we advocate for the injection of local anesthetics by the surgeon or the anesthesiologist to block postoperative pain. Local anesthetics include lidocaine, bupivacaine (also known as Marcaine), or ropivacaine. In addition, most general anesthetics include a potent inhaled anesthesia gas such as sevoflurane. Sevoflurane vapor maintains unconsciousness, blocks memory, and renders a patient pain-free, but when the surgery concludes, the anesthesia gases are turned off so that the patient will awaken. As the anesthesia gas is exhaled, a patient becomes progressively more alert, and will eventually be awake enough to feel surgical pain. The intravenous injection of a narcotic medication such as fentanyl is a common antidote to postoperative pain.

Narcotics relieve pain, but also have the undesirable side effects of respiratory depression, sedation, nausea, and constipation. Narcotics available to an anesthesiologist include morphine, Demerol, Dilaudid, or fentanyl. We commonly administer fentanyl because it has a rapid onset and rapid offset of its effect when compared to the other three drugs. The onset of action of intravenous fentanyl is less than 60 seconds. Its peak effect is at 2–5 minutes, with a half-life of 90 minutes and a duration of action of 30–60 minutes. In contrast, intravenous morphine has a slower peak effect at 5–15 minutes, with a longer half-life of 1.5–2 hours, and a longer duration of action of 3–4 hours. Because the peak effect of morphine, Demerol, or Dilaudid does not occur as rapidly as fentanyl, titrating the intravenous loading of morphine, Demerol, or Dilaudid is a slower process. Fentanyl’s rapid onset of narcotic effect is desirable because anesthesia providers quickly know whether an additional dose is necessary to achieve the titrated level of pain relief we seek. We can administer an IV dose of fentanyl every five minutes, waiting only those five minutes to evaluate how effective the preceding dose was.

Respiratory Depression:

The most serious side effect of intravenous fentanyl in anesthesia usage is the same side effect that makes street fentanyl dangerous, and that’s the side effect of respiratory depression. In layman’s terms, an excessive dose of fentanyl quickly causes a patient to stop breathing. The medical term for cessation of breathing is apnea. In an anesthesiologist’s hands, apnea is easily handled because we are skilled at ventilating oxygen into a patient’s lungs safely via a mask or an airway tube.

Street overdoses of fentanyl are best treated with naloxone (brand name Narcan). Nasal Narcan is now approved for over the counter (OTC) sale in the United States. In a medical setting, intravenous Narcan is injected to reverse a narcotic overdose. Injection of one ampule of Narcan (0.4 mg) will completely reverse narcotic apnea and unconsciousness in an overdosed patient in less than a minute.

The protocol for treating an emergency room patient who is unconscious on admission for unknown reasons includes an empirical intravenous injection of Narcan. If the patient’s coma was caused by any narcotic overdose, the patient will awaken within seconds.

Fentanyl is one hundred times more potent than morphine.  Medical fentanyl doses are prescribed in micrograms, while morphine is prescribed in milligrams. One microgram is only 1/1000 of a milligram. A narcotic as potent as fentanyl is typically only utilized by MDs expert at handling apneic patients, and the IV antidote Narcan is always immediately available. Most medical doctors other than anesthesiologists never prescribe intravenous fentanyl. Your general practitioner or primary care doctor will never prescribe fentanyl. A cardiologist may prescribe IV fentanyl sedation for a procedure such as a cardiac catheterization, or a or surgeon may prescribe fentanyl for a superficial excision surgery, but anesthesiologists are typically the only physicians who pick up a fentanyl ampule, insert a needle and syringe into the ampule, and then inject the drug into a patient’s IV. In the intensive care unit (ICU), fentanyl can be used to sedate patients who already have a breathing tube (endotracheal tube) in their windpipe, and who are on a mechanical ventilator. An ICU physician will write an order for the dosing of intravenous fentanyl, and the ICU nurse will be in constant attendance to monitor the patient’s vital signs and level of sedation.

Addiction:

Are you at risk for becoming an addict because your anesthesiologist gives you doses of intravenous fentanyl? No. Most patients have no idea they received IV fentanyl as part of their anesthetic care. The effects of fentanyl wear off within several hours after the end of the surgery, and there is no data that a patient will have a craving for additional fentanyl. After surgery, hospital inpatients who have postoperative pain are typically treated with longer acting narcotics such as morphine or Dilaudid. After surgery, outpatients who have postoperative pain are typically treated with narcotic pain pills such as Oxycontin or Norco. There is no pill form of fentanyl that a patient goes home with, or that a patient can overdose with.

Note that in medical settings, fentanyl can be given by means other than IV injection:

FENTANYL PATCH

Can medical fentanyl be stolen, find its way to the streets, and be a cause of overdose deaths of non-medical people? No. The DEA forces all hospitals, surgery centers, and medical offices to keep a strict tally of all narcotics and controlled substances. At the end of every day, a precise count of all ampules of fentanyl is done, and unless one of the doctors or nurses falsifies their count, it is unlikely any fentanyl escapes a medical facility and winds up in the hands of dealers, addicts, or individuals in the outside world.

Conclusion:

It’s true that medically administered intravenous fentanyl can cause a person to stop breathing, but if an anesthesiologist is present watching every breath, you’re safe. When an airway specialist is present and fentanyl is administered in a hospital operating room, an emergency room, an ambulatory surgery center, or a physician’s office operating room, this represents safe care in the United States today. Don’t worry if you hear your anesthesia provider is going to give you fentanyl. It’s OK. Medical administration of fentanyl has been going since the 1960s. Deaths from fentanyl overdose in a medical setting would be almost unheard of.

THE ANESTHESIA CONSULTANT

The safe management of a difficult airway is the most important single skill for an anesthesiologist. Every critically ill patient is managed by the priority of A – B – C, or Airway – Breathing – Circulation. Just as the initial most important factors in real estate are location, location, location, the three initial important factors in a critically ill patient are airway, airway, airway. I’ve written previously on the American Society of Anesthesiologists 2022 modifications to their Difficult Airway Algorithm, on the importance of expert airway management, and on advice for avoiding lost airway lawsuits, but I haven’t discussed the economic consequences of each difficult airway patient.

A 2021 publication, “Factors and Economic Outcomes Associated with Documented Difficult Intubation in the United States,”  by Moucharite et al, studied the economic cost of a difficult intubation in hospitalized patients. Using data from the Premier Healthcare Database, the study looked at adult patients with inpatient surgical admissions during 2016, 2017, and 2018. Patients in the difficult intubation group had average inpatient costs $14,468 higher than patients without difficult intubations. Patients in the difficult intubation group had average ICU (intensive care unit) costs $4,029 higher than patients without difficult intubations. For difficult intubation patients the mean hospital length of stay was 3.8 days longer and ICU length of stay was 2.0 days longer. All data were significant to a p value of < 0.0001.

In California where I practice, these numbers would be significantly higher. The mean cost of a single hospital day in California is $4181, and the mean cost of an ICU day is significantly higher.

The Moucharite study was a large retrospective review of 2,233,751 cases from hospitals in all parts of the United States. With 609 cases in the difficult intubation group and 2,233,142 cases in the non-difficult intubation group, the incidence of difficult intubation was only 0.027%. Difficult intubation patients were more likely be male, black, less than 65 years old, and have urgent or emergent admissions, obesity, cancer, congestive heart failure, COPD, renal disease, and had been treated in a teaching hospital or a hospital of 500 beds or more.

Moucharite wrote, “Difficult intubation has been associated with a variety of complications including oxygen desaturation, hypertension, dental damage, admission to the intensive care unit, and complications at extubation, as well as arrhythmias, bronchospasm, airway trauma, CICV (can’t intubate, can’t ventilate), and sequela of hypoxia (cardiac arrest, brain damage, and death). This was consistent with a 2011 study of difficult airways from the British Journal of Anesthesia which stated, “Obesity markedly increases risk of airway complications. Pulmonary aspiration remains the leading cause of airway-related anesthetic deaths. . . . Unrecognized esophageal intubation is not of only historical interest and is entirely avoidable. . . . prediction scores are rather poor, so many failures are unanticipated . . . the first-pass success rate of intubation in the operating room ranges from only 63% to 85% . . . and up to 93% of difficult intubations are unanticipated.”

The Moucharite study has limitations. It’s a retrospective study of economic Big Data, and there is no direct evidence for a cause-and-effect relationship between a difficult intubation and a more costly hospitalization. The study does not include data from electronic medical records, so we have no knowledge on all the comorbidities and complications of the difficult intubation patients. The study included only hospitalized patients, even though seventy percent of surgical procedures in the United States take place in ambulatory surgery centers and offices outside of hospitals. The reported incidence of difficult intubation  is estimated to be 1.5–8.5% of the general population, but in  the Moucharite study only 0.027% of patients were found to have difficult intubation. This discrepancy implies some patients in the Moucharite study were difficult intubations but may have been assigned to the non-difficult intubation cohort.

Note that all three authors of the Moucharite study are employees of Medtronic, a medical device company which manufactures the McGrath videolaryngoscope.

McGRATH VIDEOLARYNGOSCOPE

I expect Medtronic could cite the Moucharite study as evidence that a videolaryngoscope (such as a McGrath) is a crucial piece of equipment for avoiding expensive difficult intubation outcomes. Moucharite wrote that there is, “a need for clinicians who perform tracheal intubations to carefully consider options . . . several studies demonstrated the benefits of videolaryngoscopy [emphasis added] including a shorter time required for tracheal intubation, a higher rate of successful intubations.”

For the first look when intubating a patient, most anesthesia providers still use a traditional direct laryngoscope:

MAC 3 DIRECT LARYNGOSCOPE

 

If the direct laryngoscope does not enable a successful intubation, a reasonable second step is to switch to a videolaryngoscope such as the GlideScope, manufactured by Verathon:

GLIDESCOPE

or the C-MAC, manufactured by Karl Storz:

C-MAC

 

or the McGrath, manufactured by Medtronic:

McGRATH VIDEOLARYNGOSCOPE

 

In my experience the larger 6.4-inch screen on a GlideScope or the 5.9-inch screen on a C-MAC makes them superior videolaryngoscopes to the McGrath with its diminutive 2.5-inch screen.

Why use a direct laryngoscope in the initial intubation attempt rather than use a videolaryngoscope? A direct laryngoscope costs less than a videolaryngoscope. Most direct laryngoscopes blades are washed and reused. Videolaryngoscopes require a new disposable sleeve or blade for every case. In facilities with budget concerns, replacing all traditional laryngoscopes with videolaryngoscopes would be expensive. A McGrath costs about $2500 on eBay, and each new nonreusable blade cover costs about $10. A new GlideScope was $12,745 in 2017. A reconditioned GlideScope costs between $1000 and $10,000 on eBay, and each new nonreusable blade costs $38.

A 2022 study comparing direct laryngoscopy to videolaryngoscopy concluded that “videolaryngoscopy likely provides a safer risk profile compared to direct laryngoscopy for all adults undergoing tracheal intubation.” A recent review  stated that, “Though videolaryngoscopes have been recommended for use at first attempt of intubation by most international airway guidelines, the universal use of videolaryngoscopes is still facing hurdles because of limited training opportunities, availability and high cost.”

Should a videolaryngoscope replace a direct laryngoscope for all initial intubation attempts? I don’t think so. The majority of intubations are straightforward and are successful with a Miller 2 or a Mac 3 direct laryngoscope. Should a videolaryngoscope be available as a back-up piece of equipment for every intubation? Absolutely. The ASA Difficult Airway Algorithm includes the possible use of a videoscope, and states,
“Consider the relative merits and feasibility of basic management choices:  (consider) video-assisted laryngoscopy as an initial approach to intubation.” An anesthesia provider who initiates general anesthesia and intubation without an immediately available videolaryngoscope is in danger of not being able to follow the algorithm. The hospital I work in is stocked with either the GlideScope and the C-MAC both readily available for difficult intubations. The availability of a videolaryngoscope for either a first attempt or for backup attempts to intubate a difficult airway patient is vital.

Difficult airway cases can lead to malpractice claims. A 2009 study published in Anesthesiology showed that 2.3% of 2,211 anesthesia-related deaths in the United States from 1999-2005 were attributable to difficult intubation and failed intubation.  A 2019 study from the Anesthesia Closed Claims Project database showed that the 102 difficult intubation closed malpractice claims from 2000 to 2012 included sicker patients (n = 78 of 102), emergency procedures (n = 37 of 102), and non-perioperative locations (n = 23 of 102).  Preoperative predictors of difficult tracheal intubation were present in only 76% of the patients. Inappropriate airway management occurred in 71 patients. A “can’t intubate, can’t oxygenate” emergency occurred in 80 of the 102 claims, with a delayed surgical airway occurring in 39% of those cases. The authors wrote, “outcomes remained poor in recent malpractice claims related to difficult tracheal intubation. Inadequate airway planning and judgment errors were contributors to patient harm.”

In conclusion: Difficult intubations are a major anesthesia problem, because of: 1) the difficulty in identifying difficult intubation patients prospectively, 2) the medical comorbidities that occur with difficult airway patients, 3) the medical complications that can occur if difficult airways are mismanaged, 4) the dollar cost of increased healthcare utilization as reported in the Moucharite study, and 5) the potential medical-legal liability risk with each difficult intubation.

THE ANESTHESIA CONTROL TOWER: BIG BROTHER OR FRIEND?

THE ANESTHESIA CONSULTANT

The Barnes Jewish Hospital, Washington University, St. Louis

Imagine this: You’re an anesthesiologist in the operating room at a busy hospital. Your patient is in mid-surgery, and you receive a call from the Anesthesia Control Tower that the patient’s blood pressure is too low, your blood transfusion replacement is inadequate, and that the patient is in danger. What do you do? How do you feel about all this?

Anesthesiologists at Barnes Jewish Hospital at Washington University in St. Louis, Missouri are studying a novel system they call the Anesthesia Control Tower (ACT). The ACT is a telemedicine-based intraoperative clinical support system.  A team led by an attending anesthesiologist uses remote monitoring to provide evidence-based support to anesthesia colleagues in all the operating rooms. The ACT is similar in concept to an air traffic control tower. The clinicians in the Anesthesiology Control Tower, called ACTors, monitor operating rooms (ORs) in real time by following the electronic health records. Just as an air traffic control tower monitors aircraft and delivers information and alerts to the pilots, the ACT communicates with anesthesia providers to assist them in providing safe care.

A press article describing the ACT states: “Surgery is a big insult to the human body. A lot can go wrong. In fact, it does. An estimated 10 to 20 percent of patients who undergo major inpatient surgery experience major complications such as heart attacks, unremitting pain, infections, and blood clots in the weeks to months following their procedures; about two percent are dead within 30 days of surgery. Some of this morbidity and mortality may be preventable through early identification of risk factors and better communication to mitigate risks during the surgery. . . . Air traffic control concepts can predict high risks for healthcare complications and improve decision making.”

The Washington University ACT provides a watchful eye over 60 operating rooms at Barnes-Jewish Hospital, watching over nearly 1,000 patients per week.  

A software program used in the ACT is called AlertWatch®. The ACT anesthesiologist (ACTor) watches a monitor displaying the Tower Mode census view (Figure 1 below), which shows an overview of all the patients in the ORs. Alerts or abnormal vital signs and laboratory results are represented by squares and triangles, respectively. Checkmarks indicate alerts that must be addressed by the ACT. The Tower Mode view looks like this (Figure 1):

 

Figure 1   Census View, Anesthesia Tower

 

The Tower Mode includes a display for each individual patient (Figure 2 below). The organ systems are labeled with relevant physiologic variables and values. Colors outline each organ, and include normal (green), marginal (yellow), or abnormal function (red). The left side of the display shows patient case information. Information regarding the patient’s medical problems can be accessed by selecting the organ system or laboratory study of interest. The black checkmark at the bottom of the left panel indicates that there is an active alert for the ACT clinicians to address (Figure 2 below):

Figure 2 Individual Patient Display, Anesthesia Tower 

 

Clicking on the checkmark opens the case review dialogue, which looks like this (Figure 3):

Figure 3, Case Review Dialogue, Anesthesia Tower

The Anesthesia Control Tower is physically located within the hospital complex, but is remote from the operating rooms. Washington University has expanded the ACT to include the Recovery Control Tower, which provides similar surveillance over patients in the Post Anesthesia Care Unit (PACU).

This photograph below depicts the Anesthesia Control Tower manpower at work at Barnes Jewish Hospital at Washington University in St. Louis:

Monitoring surgeries from the Anesthesiology Control Tower (left to right): Omokhaye M. Higo, MD, vice chair for innovation, Thaddeus Budelier, MD, program manager for the Perioperative Innovation Center, and Bradley A. Fritz, MD, assistant professor of anesthesiology, Washington University Medical School.

 

Some anesthesiologists were initially skeptical about the ACT idea. But Washington University Anesthesia Chairman Dr. Michael Avidan stated, “Most of the skepticism has evaporated over time as clinicians have perceived that innovation and technology are not threats, but rather enhancements. The conceptualization of our Perioperative Innovation Center is more akin to ‘phone a friend’ than it is to a sinister ‘big brother.’”

Current staffing levels of anesthesia professionals in the United States are inadequate. The shortage of anesthesia professionals, particularly in rural areas, may someday be remedied by a telemedicine system which resembles the ACT.  We may someday see anesthesia managed by less highly trained persons in the OR, with an ACTor backing them up by watching from on high.

Anesthesiologists who supervise Certified Registered Nurse Anesthetists (CRNAs) or Anesthesia Assistants (AAs) in an anesthesia care team model often have to provide care for multiple patients simultaneously. These attending anesthesiologists cannot physically be present in multiple operating rooms at all times. These anesthesiologists may be aided by Anesthesia Control Tower technology, which continually assesses patients for signs of deterioration and alerts the attending anesthesiologist when an adverse event is brewing.

If the Anesthesia Control Tower is to become a standard in hospital care, we need to know if the ACT changes medical outcomes. Washington University is conducting a study randomizing thousands of adult surgical patients in their operating rooms to an intervention group (ACT) or to a control group without ACTAn estimated 10,000 patients will be enrolled per year, and over four years  approximately 40,000 total patients will be enrolled. Data from this study are as yet unavailable.

The goals of this clinical trial are 1) to develop machine-learning algorithms for forecasting perioperative adverse events; 2) to develop a clinical decision support system that suggests interventions based on the algorithms, and 3) to change the paradigm of perioperative care.

Will physicians and patients see the ACT model in the near future? Significant issues regarding the adoption of Anesthesia Control Tower technology include:

  1. Documenting that ACT provides an improvement. A critical barrier for anesthesiologists, hospitals, and policy makers nationwide will be documenting that the ACT demonstrates an improvement in costs, patient outcomes, or patient experience. None of these things are apparent at this time.
  2. Paying for the ACT equipment and the ACTor on duty will be an issue. Additional hardware and software would be required at each hospital. An in-person anesthesiologist is already being paid to do each case, and the ACTor is another level of anesthesia staffing someone is going to have to pay for.
  3. Anesthesiologist opposition. A challenging barriers will be how anesthesiologists perceive systems like the ACT. Anesthesiologists are trained to be vigilant and manage their patients themselves. Having the ACT peering into the operating room, perhaps with a video camera watching the operating room, will likely be unpopular with the anesthesiologists being observed. There may also be concern that data from the ACT could be used against physicians in the event of a malpractice lawsuit. When the topic of the Anesthesia Control Tower was breached, one of my physician anesthesiologist colleagues remarked, “If that system becomes standard, I’m quitting.”
  4. Lack of need for an ACT in ambulatory settings. According to a 2017 study by the Centers for Medicare and Medicaid Services, the majority of surgical procedures in the United States, fully 70 percent, occur in ambulatory surgery centers or offices outside of hospitals. These outpatient procedures are predominantly smaller surgeries conducted on healthier patients. These smaller ambulatory facilities would have no use for the ACT, both because patients are healthier and because the surgical procedures incur less risk and fewer complications. The costs of an ACT in these smaller settings would be unlikely bring any benefit.
  5. Flawed analogy. Air traffic controllers exist to coordinate takeoffs and landings, so planes do not collide with each other in the air or on the runways. In anesthesiology, operating room patients will not collide with each other and do not have traffic issues with each other. Instead, the Anesthesia Control Tower will scrutinize each patient’s data for abnormalities that will predict a pending complication.
  6. The ACT and the algorithms developed through the ACT will likely be a transitional technology. Having one anesthesiologist (the ACTor) overseeing multiple operating rooms will likely be a steppingstone to Artificial Intelligence technology in which a computer oversees the data from each operating room, with the aim to detect and prevent adverse outcomes from developing. The arrival of ChatGPT foreshadows the AI technology about to bloom in healthcare. In the future the anesthesia provider in each operating room will likely be backed up by AI technology enforcing algorithms, rather than being backed up by a human in a control tower. I described this healthcare evolution in my 2019 book Doctor Vita, in which Artificial Intelligence in the form of inexpensive, internet-connected computers took over a California medical center and changed the face of medicine forever.

Improving vigilance and improving outcomes is the ultimate goal of ACT technology. Further data on the Anesthesia Control Tower will be forthcoming. We’ll await the prospective controlled studies, and then we’ll all learn whether or not this technology is an advance to help patients and physicians.

THE ANESTHESIA CONSULTANT

An astronaut en route to Mars develops severe abdominal pain, nausea, and vomiting. A fellow crew member examines him and finds significant tenderness and guarding in the right lower quadrant of his abdomen. The crew members teleconference with physicians on Earth, with a 20-minute communication delay because of the 140-million mile distance between them. The physicians confirm a probable diagnosis of appendicitis. Because the spaceship is more than 200 days away from Earth, the physicians instruct the crew to proceed with surgery and anesthesia in outer space.

Outer space medical care will certainly not resemble Dr. Leonard “Bones” McCoy on the original Star Trek, who waved his fictional handheld “tricorder” tool over a patient to diagnose and treat the patient’s illness.

How will astronauts conduct general anesthesia and surgery in outer space? Is an anesthesiologist required on board? Is a surgeon required on board? If the flight crew doesn’t include any physicians, how will the crew proceed to save the astronaut’s life?

Full disclosure: I’ve never given an anesthetic in outer space. But to date, no one else has given an anesthetic to a human in outer space eitherProtocols regarding how to accomplish anesthesia in outer space exist in the medical literature.

For comprehensive reading I’d refer you to three papers by expert Matthieu Komorowski MD, an anesthesiologist, intensive care physician, and biomedical engineer at Imperial College London, and a former Research Fellow at the European Space Agency. Three of Komorowski’s key articles are: “Anaesthesia in outer space, the ultimate ambulatory setting?” in Current Opinion in Anaesthesiology; “Fundamentals of Anesthesiology for Spaceflight,Journal of Cardiothoracic Vascular Anesthesia, andPotential Anesthesia Protocols for Space Exploration Missions in Aviation Space Environmental Medicine.

Distant space missions, known as exploration class missions (e.g. missions to the Moon and Mars) are planned in the coming decades. Staffing an astronaut/physician as one of the crew members on a mission to Mars is possible, but I have no information that the National Aeronautics and Space Administration (NASA) is grooming a combination astronaut/anesthesiologist at this time.  In 2017, NASA created an Integrated Medical Model (IMM) as an evidence-based decision support tool to assess risks and design medical systems for extended space travel. The IMM includes 100 medical conditions that might commonly occur during space flight. Twenty-seven of these 100 conditions would require surgical treatment.

The most significant medical risks for space exploration missions are trauma, hemorrhagic shock, and infections. The risk of a medical emergency in space travel is estimated at one event per 68 person months. For a crew of six on a 900-day mission to Mars and back, at least one medical emergency would be expected. On a mission to Mars, the option of a stat return to Earth is impossible. Telemedicine can provide remote communication for medical consultation. While telecommunication between the Moon and Earth would have delays of only 2 seconds in each direction, for a Mars mission the delay in communications could reach up to 20 minutes in each direction, making real-time telemedicine impractical. The communications delay on a Mars mission would also mean that a surgical robot on board could not be controlled by a surgeon on Earth. The crew must be self-reliant.

Only physically and mentally fit candidates who are able to withstand the stresses of space travel are selected as astronauts. Physically and mentally fit candidates are at low risk for medical or surgical emergencies. But with the recent trend of privately funded space programs (e.g. SpaceX), some members of the general public may be offered the opportunity to experience space travel. Privately funded programs may push boundaries regarding the undesirable health status of candidates traveling into space.

PHYSIOLOGIC CHANGES IN SPACE

To devise safe anesthetic care for outer space, one must first understand the changes in an astronaut’s body during microgravity. The void of outer space provides a lack of barometric pressure, a lack of oxygen, severe extremes of temperature, and dangerous levels of radiation. Spacecraft are equipped with Environmental Control and Life Support Systems (ECLSS) to ensure livable conditions within the space capsule.  Weightlessness and microgravity cause marked changes in human physiology, described by systems as follows:

Cardiovascular system 

Microgravity causes fluid to redistribute toward the upper half of the body, resulting in facial and airway edema (swelling), and diuresis (increased urination) which leads to an intravascular volume decrease of 10-15%. The systemic vascular resistance in the arterial system decreases about 14% because of dilatation of the blood vessels, but the left ventricular systolic function of the heart is maintained near normal.

 

Gastrointestinal system

Weightlessness causes a combination of decreased gastric motility and increased gastric acidity. If an astronaut requires general anesthesia, one must assume the patient has a full stomach and is at risk for aspiration.

Respiratory system

Microgravity leads to an increase in respiratory rate and a decrease in tidal volume, resulting in near normal ventilation.

Neurologic system

Microgravity interferes with inner ear function, and causes disturbances in balance and vestibular function. Constant exposure to artificial lighting alters sleep rhythms, and predisposes the crew to impaired mental acuity and depression.

Musculoskeletal system

Weightlessness and inactivity cause an increase in bone resorption. Bone density decreases by about 1% per month, which predisposes astronauts to long bone fractures and kidney stones secondary to increased calcium excretion. Prolonged microgravity leads to deconditioning of the muscular system with skeletal muscle atrophy. This is most marked in the lower body, as the legs become “effectively redundant.” 

 

 

REGIONAL ANESTHESIA VERSUS GENERAL ANESTHESIA

IV fluids

Every anesthetic, regional or general, will require the patient to have an intravenous line, usually in their arm. Astronauts will be trained in the insertion of IV cannulae, and the sampling of blood for diagnostic tests. Storage of prepackaged intravenous fluids can occupy a large volume of precious cargo space. An exploration class mission may require up to 100 liters of IV fluids in case of severe burn injuries. Scientists have developed a system named IVGEN (Intravenous Fluid Generation) to prepare sterile IV normal saline from space station drinking water.

Bubbles in the IV fluids are dangerous, and are filtered out by the system, because bubbles could form air emboli and cause a stroke or a heart attack if they entered the body. Transfusable blood products have a limited shelf life, which makes an onboard blood bank impractical for prolonged space travel. Medical checklists will aim to ensure patient safety and help the astronauts gain familiarity with medical equipment and drugs. Medical kits on board will include a basic vital signs monitor, a mechanical ventilator, an ultrasound machine, suction, airway equipment, and a limited range of drugs with protocols regarding how to use them.

Monitors

Standard patient monitoring would include ECG, non-invasive blood pressure cuff, oxygen saturation, end-tidal CO2, and temperature. Preoperative ultrasound examination can be applied for diagnostic use, the assessment of cardiac function and fluid status, and assistance in visualizing blood vessels for peripheral or central line placement.

REGIONAL ANESTHESIA

A regional technique offers simplicity over general anesthesia, but a successful regional anesthetic requires skill, experience, training, and regular use of such skills. Studies on Earth show that an average of 20 procedures are required to reach a learning curve plateau. A practitioner must be schooled in regional anesthesia techniques on Earth prior to the space flight. The three suggested regional blocks to treat the majority of conditions expected to be encountered in space include femoral, sciatic, and brachial plexus nerve blocks. The blocks would be ultrasound-guided, and there is hope that AI-imbedded ultrasound technology will be available in the future to localize relevant structures such as nerves and blood vessels. The injection of a local anesthetic such as ropivacaine for a regional techniques carries the inherent risk of local anesthetic toxicity. The antidote for local anesthetic toxicity is lipid emulsion, which could occupy valuable space on board, and has a shelf life of only 24 months. Spinal blocks are impractical, as the use of typical hyperbaric local anesthesia such as 0.75% bupivicaine has not been investigated in microgravity to date.

GENERAL ANESTHESIA

General anesthesia has the advantages of a quick and reliable onset. The physiologic changes during microgravity predispose a general anesthesia patient to both aspiration of stomach contents and hypotension due to low intravascular volume. Each general anesthetic would require a preinduction loading with intravenous fluid replacement, followed by a rapid sequence induction and endotracheal intubation. In the absence of gravity, restraints will be required to keep the patient immobile for intubation.

Ketamine

Potent anesthetic gases such as sevoflurane cannot be used in outer space, as vaporizers will not function properly in microgravity. General anesthesia will include intravenous medications only. Ketamine will be the preferred drug of choice for induction of general anesthesia, as spontaneous respiration and cardiovascular stability are maintained. Ketamine induces both a dissociative state and analgesia, and has an extended shelf life of around 20 years in powder form. It’s currently used in remote locations on Earth where there is limited equipment and monitoring (e.g. combat anesthesia in low-income countries). The unpleasant psychomimetic side effects of ketamine are negated by the co-administration of an IV benzodiazepine such as midazolam or Valium. Intravenous atropine will also be administered to minimize the increased oral secretions produced by ketamine.

A muscle relaxant/paralytic drug is recommended to facilitate endotracheal intubation. Succinylcholine will not be used because of its ability to cause hyperkalemia. Rocuronium at a modified rapid sequence dose of 1mg/kg is recommended. A checklist and a PowerPoint presentation on the sequence of drugs and procedures needed to initiate general anesthesia will be available for the astronauts to read prior to and during the administration of general anesthesia. A video laryngoscope will be available, as it is recognized as an easier technique for inexperienced practitioners to complete successful endotracheal intubation. A publication by Komorowski and Fleming, “Intubation after rapid sequence induction performed by non-medical personnel during space exploration missions: a simulation pilot study in a Mars analogue environment,” demonstrated that intubation can be done by non-medical staff with little or no training via instructions from PowerPoint slides.

An intravenous infusion of ketamine is recommended for the maintenance of general anesthesia. Opioids are unlikely to be carried on a spacecraft. It’s likely the analgesic effects of ketamine will be used for acute pain relief. Sugammadex will be available to reverse the neuromuscular blockade from rocuronium, and neuromuscular monitoring will be utilized prior to extubation.

SURGERY IN SPACE

Restraining the surgeon, the patient, and the surgical tools against floating around the room in zero gravity are challenges to overcome in outer space. Magnetizing the surgical tools so they stick to the operating room table, and restraining the astronaut/surgeon and the patient are important adjustments. Surgery involving anesthesia was successfully performed on rodents for the first time in 1990 on the STS-90 Neurolab Space Shuttle. Astronauts repaired rat tails and performed laparoscopy on rodents in microgravity. It’s possible that insufflation of the human abdomen with carbon dioxide gas during laparoscopy in microgravity may cause changes in cardiac or respiratory function. During open abdominal surgery in microgravity, a patient’s intestines would float around and could obscure the view of the surgical field. Because of the large array of surgical equipment necessary for any specific surgery, a 3D printer on the spacecraft may be the solution to create tools as needed.

Bleeding in microgravity causes domes to form around the bleeding site. The domes are held in that shape because of surface tension. Enclosed surgical chambers have been developed to protect the sterile surgical field and the cabin environment during open surgeries in zero gravity. A hermetically sealed expandable surgical chamber for microgravity is called a “surgical overhead canopy” (SOC). The surgical repair can be performed within the canopy, and the canopy prevents organs or blood from floating about the cabin.

Anesthesia in Outer Space – Conclusion

For the appendicitis case introduced in paragraph one, the anesthetic would include the IV loading of 500 ml of normal saline; a rapid sequence intravenous induction of general anesthesia using ketamine, midazolam, atropine, and rocuronium; placement of an endotracheal tube into the patient; and an IV ketamine infusion for the maintenance of anesthesia. Once the patient is anesthetized, the surgery could either proceed as an open abdomen under a sterile surgical canopy, or a laparoscopy with the abdomen remaining closed, depending on the skillset and the surgical equipment available to the surgeon/astronaut on board.

One day an astronaut will perform the first anesthetic on a human in outer space. The astronaut will most likely not be a board-certified anesthesiologist, and he or she will likely follow a PowerPoint slide show demonstrating the sequence of procedures and pharmacology for successful anesthesia. Expect the first anesthetic in space to be a tense, exciting, and dramatic event in the history of medicine.

THE ANESTHESIA CONSULTANT

Dr. Jed Wolpaw, the host of ACCRAC

 

An anesthesia education success story:

I was administering a mock oral board exam to a Stanford first-year anesthesia resident in November 2022, and the young man aced the test. He exceeded the knowledge base and judgement of his peers by a significant margin. After the exam, my co-examiner and I asked him how much medical training he’d had to date. He answered that he’d graduated from medical school, completed a one-year internship, and had been an anesthesia resident for (only) 4 months.

“How do you know so much about anesthesia already?” I asked.

“Almost everything you asked me I knew from keeping up with ACCRAC,” he said.

“What’s ACCRAC?” I asked.

He answered, “I was at Johns Hopkins for an anesthesia rotation, and I met Dr. Jed Wolpaw, one of the Critical Care faculty, who has a website called ACCRAC, which is a collection of anesthesia podcasts.”

ACCRAC stands for “Anesthesia and Critical Care Reviews And Commentary.” Our Stanford resident had listened to the podcasts on Dr. Wolpaw’s website for over one year, and as a result he was wise beyond his age concerning anesthesia information and decision making.

I accessed the ACCRAC website and found a wealth of information, with more than 240 podcasts pertaining to anesthesia. The majority of the podcasts were Dr. Wolpaw interviewing experts from different aspects of anesthesia or critical care. The podcasts varied from #1 (June 14, 2016)  “Properties and laws of volatile anesthetics”  . . .  to #247 (January 30, 2023) “Kali Dayton discussing her work helping ICUs around the country learn how to get their intubated patients awake, up and walking, by implementing the ABCDEF bundle.”  The podcasts are audio only. Continuing Medical Education (CME) credit is available from the website. I found ACCRAC to be the most extensive and comprehensive array of anesthesia podcasts on the internet.

I contacted Dr. Wolpaw and told him the Stanford resident’s success story. I queried him about his website and his podcasts. These were his answers to my questions:

  1. What was your impetus for initially starting ACCRAC? What void in anesthesia education did you identify?

“When I was an intern in Emergency Medicine, I listened to EMRAP (Emergency Medicine Reviews And Perspectives) as did every resident I knew, and many attendings as well.  It was a fabulous source of information and learning.  When I switched into Anesthesiology, I looked for the equivalent podcast but it didn’t exist.  I always had in the back of my mind that someday I might try to start one.  When I became an attending and heard our residents asking for audio resources, I knew it was time.”

  1. Why did you choose podcasts rather than a website of written words?

“I wanted something that people could listen to while commuting or working out, something that wouldn’t add a burden to their already busy day.  Audio only podcasts are really the only way to do that.” 

  1. How do you select your guests?

“I look for interesting articles, or approach people who give talks I find intriguing.  I also get lots of proposals from people who are doing interesting things and are interested in coming on the show.  And I get tons of emails from listeners requesting certain topics.  I can’t do them all, but I try to get to as many as possible.”

  1. What percentage of your guests are from Johns Hopkins? 

“I’m not sure of the exact number but certainly a fair amount, I’d guess maybe 70% or so.” 

  1. Is your target market residents and fellows? How about university professors, or community anesthesiologists?

I certainly think we have a lot of content that is useful to trainees, but we also have a large number of practicing anesthesiologists, both academic and private practice, who listen (and some use it for CME) as well as nurses, CRNAs, AAs, medical students and others.”

  1. Is any aspect of ACCRAC directed toward laypeople?

“Not really, but I have done some episodes that are accessible to the lay public like a review of the book The Obesity Code, and an interview with Dr. Richard Harris who helped rescue the Thai Boys Soccer Team from a flooded cave in 2018.” 

  1. You trained at UCSF, arguably the nation’s finest anesthesia program. How does Hopkins compare to UCSF? Is there a West Coast-East Coast difference? 

“I think they are both fabulous programs.  I honestly find more similarities than differences and apart from the weather haven’t noticed much of a coastal difference.” 

  1. What are 5 or 6 of your favorite podcasts, to direct my readers to?

“I really enjoyed my conversation with Dr. Harris about the rescue of the soccer team.  The interview with Dr. Bobbie Sweitzer was also great because she pokes holes in so many assumptions we have.  I think the episode with Christian Meyhoff is also a great one since we talk about his surprising findings and why they might have come out that way.  And the same is true of my talk with Mark Neuman  about his New England Journal of Medicine (NEJM) paper.   And my conversation with Wes Ely about his book Every Deep Drawn Breath was really compelling.”

  1. How labor-intensive is it to maintain and add to ACCRAC? I notice six other individuals on your home page who assist you. 

“It’s a fair amount of work, but I really enjoy it.  I’m lucky to have volunteers who handle the social media accounts and help with the website.  For now the preparation, interviews, recording, and editing is all me but it’s manageable.” 

  1. I see that you published Podcasting as a Learning Tool in Medical Education: Prior to and During the Pandemic Period,” a reference regarding podcasting. To what extent do you see podcasting growing in medical anesthesia?

“I think we’ll see significant growth.  Emergency Medicine is a great example where there are podcasts covering all sorts of sub-specialty topics and niche interests.  We’re already starting to see some growth in Anesthesiology with great podcasts like Depth of Anesthesia and I think we’ll continue to see more.”

****

Googling the topic of “anesthesia podcasts” reveals Dr. Wolpaw’s website on the first page. Other leading sources of anesthesia podcasts include:

The American Society of Anesthesiology (ASA) presents four categories of podcasts, including (1) ASA’s Central Line, which “features leaders in our field discussing a wide variety of challenges and opportunities vital to our practice and our profession.” (2) Residents in a Room, “a podcast series for residents, by residents, featuring anesthesiologists-in-training from across the country, putting it all out there, discussing their hopes, fears and expectations for residency and beyond.” (3) ANESTHESIOLOGY featuring the “Editor-in-Chief of Anesthesiology and his monthly overview of new journal content (translated in multiple languages) and featured author podcasts that highlight research through author and editorialist interviews; (4) Summaries of Emerging Evidence (SEE), featuring “a sneak peek of the most interesting studies covered the latest edition of the popular continuing education program.”

The International Anesthesia Research Society/OpenAnesthesia presents a link to hundreds of podcasts, including interviews from anesthesia experts from 2009 – present.

Great Britain’s Association of Anesthetists, and their journal Anaesthesia, have a website which includes 38 podcasts to date.

Harvard’s Massachusetts General Hospital presents Depth of Anesthesia, a collection of 38 podcasts to date.

Feedspot ranks the top anesthesia podcasts at this link.

Podcasts present a significant means of communication, information, and entertainment in the United States. Per The Infinite Dial report by Edison Research and Triton Digital, “As of 2021, 41% of Americans ages 12 or older have listened to a podcast in the past month, . . . up from 37% in 2020 and just 9% in 2008. Additionally, 28% of those 12 and older said they have listened to a podcast in the last week, up from 24% in 2020 and 7% when this was first measured in 2013.” Per Pew Research Center, “About a quarter of U.S. adults (23%) say they get news at least sometimes from podcasts.

Dr. Wolpaw’s 2022 publication, “Podcasting as a Learning Tool in Medical Education: Prior to and During the Pandemic Period,” makes the following important points about medical podcasts:

  1. “By entering a query for the term “podcast” in PubMed, a year-by-year breakdown of the number of publications with this term in the title shows an increasing trend from 2006 to 2022.”
  2. “For the creator, podcasting is a relatively low-cost endeavor, allowing for a low bar for entry into the podcasting space.A feasibility study conducted for the creation of an ophthalmology podcast revealed that start-up costs were just $212.18 with $29 monthly expenses.”
  3. “One review found that listeners find learning from podcasts to either be equivalent to, or better than, classroom learning.”
  4. “Multiple studies have found that listeners of medical education podcasts felt more motivated to learn.”
  5. “Rather than waiting on peer-reviewed literature, which could take several months to begin to show up, the rapidly evolving nature of the early pandemic required a faster means of propagating information to clinicians. Podcasts were a way by which-as early as February and March of 2020-anecdotal experiences from physicians across the world could be shared before peer-reviewed literature could be published.”

I find the primary advantage of podcasts is that one can listen to them while multitasking. I find a disadvantage in that, unlike a written article, one cannot skim over the content looking for the most pertinent sentences or paragraphs. If a podcast lasts 20 minutes, you’re committed to listening to every word, or to utilizing an available fast forward button for a 30 second leap to a later time. Another disadvantage is the inability to visually display internet links to references. With a written article, one can click on links to other published articles mentioned in the text. Dr. Wolpaw’s publication states that “many podcasts in medical education also utilize show notes-summary documents that accompany podcast episodes. These documents outline the episode’s main points and contain references to resources discussed in each episode.”

Podcasts are mainstays of 21st century media. The freedom to educate yourself while driving a car, doing chores, or exercising is a terrific opportunity for medical professionals. Until I discovered ACCRAC, I was not a podcast listener. Now I am, and I recommend the same to you. Podcasts won’t replace the written words of anesthesia textbooks or journals, but podcasts can be enjoyable and informative, and they have a definite role in supplementing medical education.

THE NEW 2023 ASA GUIDELINES FOR QUANTITATIVE NEUROMUSCULAR MONITORING. NOW WHAT?

THE ANESTHESIA CONSULTANT

The 2023 American Society of Anesthesiologists Practice Guidelines for Monitoring and Antagonism of Neuromuscular Blockade were published last month.The paper is backed by strong science, and references an exhaustive list of no less than 277 previous publications on the topic, including this review. The paper concludes that quantitative neuromuscular (NM) monitoring is the most accurate and clinically useful technology for detecting residual neuromuscular block.

The problem? Very few anesthesia professionals have access to a quantitative NM monitoring device at present.

Currently a large number of anesthesia practitioners don’t monitor neuromuscular blockade level at all. A 2010 survey documented that 9.4% of American anesthesiologists didn’t use a peripheral nerve stimulator, and most survey respondents felt that neither conventional nerve stimulators nor quantitative neuromuscular monitors should be part of minimum monitoring standards. An editorial accompanying the 2023 ASA Guidelines states, “it is impossible to accurately predict the depth of neuromuscular block or the adequacy of reversal by using clinical tests such as tidal volume, negative inspiratory force, ability to sustain head lift, or grip strength. Similarly, qualitative assessment of responses to peripheral nerve stimulators cannot be relied upon in deciding the appropriate time for tracheal extubation.”

The most important recommendations from these ASA Practice Guidelines, each backed by Strong Strength of Recommendation (bold text by me) are:

  1. When neuromuscular blocking drugs are administered, we recommend against clinical assessment alone to avoid residual neuromuscular blockade, due to the insensitivity of the assessment.

  2. We recommend quantitative monitoring over qualitative assessment to avoid residual neuromuscular blockade. When using quantitative monitoring, we recommend confirming a train-of-four ratio greater than or equal to 0.9 before extubation.

  3. We recommend using the adductor pollicis muscle for neuromuscular monitoring.

  4. We recommend against using eye muscles for neuromuscular monitoring.

  5. We recommend sugammadex over neostigmine at deep, moderate, and shallow depths of neuromuscular blockade induced by rocuronium or vecuronium, to avoid residual neuro- muscular blockade.

Recommendation #2 will be the most challenging to follow, because, as an October 2021 study published in Anesthesiology states, “The paucity of easy-to-use, reliable objective neuromuscular monitors is an obstacle to universal adoption of routine neuromuscular monitoring.” In 2016 there were more than 224,000 operating rooms in the United States, so tens of thousands of devices could be needed.

What type of quantitative NM monitoring device should we aim to acquire? There are three types of quantitative monitors of neuromuscular blockade discussed in a 2021 Anesthesiology editorial. I quote from this reference:

1. Acceleromyography. Depolarization of the ulnar nerve results in contraction of the adductor pollicis, which flexes the thumb, producing an acceleration detected by the sensor. . . . the thumb must be entirely free to move, which precludes monitoring the hand that has been tucked at the patient’s side during surgery. The second problem is that the baseline, unparalyzed train-of-four ratio (the ratio of the fourth to the first twitch of a train-of-four), which should theoretically be equal to 1, is often greater than 1.

Acceleromyography monitoring

2. A mechanomyograph is an instrument that directly measures the isometric force of contraction of the thumb, using a force transducer. . . . A mechanomyograph is a somewhat cumbersome instrument that has been used primarily for research, and very seldom for routine clinical practice. Currently, mechanomyography is not commercially available.

3. Electromyography directly measures the compound action potential of the adductor pollicis muscle. . . No movement is required for this measurement to be made. The hand can be tucked at the patient’s side without any significant effect on the electromyogram. . . . A baseline, unparalyzed train-of-four ratio is not required. 

electromyography (EMG)

Electromyography (EMG) is the most promising of the three devices. The Nemes et al study, performed in Hungary, established that EMG compares favorably to acceleromyography, stating, “The EMG-based device is a better indicator of adequate recovery from neuromuscular block and readiness for safe tracheal extubation than the acceleromyography monitor.” The Nemes study utilized an EMG called a TetraGraph.

Where can you buy a TetraGraph? A Google search for this device leads us to a website for a company called Senzime.

TetraGraph and TetraSens EMG unit

The TetraGraph received FDA 510 clearance in 2019. Dr. Sorin J. Brull, the author of the Anesthesiology editorial on the 2023 NM Practice Guidelines, is a principal, shareholder, and the Chief Medical Officer in Senzime, as well as a Professor Emeritus of Anesthesiology and Perioperative Medicine at the Mayo Clinic.

I contacted a representative of Senzime, who demonstrated the device to me. I learned the following:

  • Senzime’s TetraGraph is manufactured in Sweden. The device has been improved and modified over the past 3 years.
  • The TetraGraph NM monitoring device clamps to an IV pole, and is slightly larger than an iPhone.  A disposable TetraSens sticker of sensing electrodes attaches to the patient’s wrist over the ulnar nerve, and extends distally to adhere to the skin over either the pinky or the thumb. The hand can be tucked out of sight and the EMG technology will still reveal accurate data.
  • The Tetragraph attaches to the TetraSens via a cable.
  • The Tetragraph screen displays a button labelled “AUTO,” which will activate serial trains-of-four at a preselected interval, for example, every 20 seconds.
  • The screen on the device is usually set to display four bars in a bar graph, representing  the measured EMG amplitude of the train of four. At control the quantitative NM score will be 100%, as all four twitches are equivalent. Once a muscle relaxant is administered to the patient, the bar graph will change, showing decreased heights of the bars dependent on the dose and time of the muscle relaxant.

TetraGraph bar graph screen depicting Train-of-Four

 

  • The anesthesiologist should wait until the quantitative NM score is 90% or greater, prior to extubation.
  • The hardware retails for $2000 – $2500 per unit. The disposable stickers that adhere to the patient’s hand are $20 each. The unit can be annexed to certain patient monitoring systems, and data can be input into an Electronic Medical Record system. Senzime’s website https://senzime.com/about-us/ceo-statement/  outlines the company’s intention to combine TetraGraph with Masimo’s patient monitoring system, stating “Our ambition is to submit the module developed to connect TetraGraph® with Masimo’s patient monitoring system Root® for approval at the end of 2023, and to launch at the beginning of 2024.”
  • To date Senzime has sold 300+ units in the United States. Several large hospital systems, including the University of Arizona, Duke, University of North Carolina, and the Medical College of Wisconsin have purchased the devices for their operating rooms. Multiple other large hospital systems are on the verge of completing purchases of 100-200 units as of January 2023. Senzime has an inventory to accommodate such purchases, and a clinical team positioned to help medical centers or surgery centers try out and/or adopt the technology.

 

Will Senzime have a monopoly or near-monopoly on this new technology? Time will tell. A Google search for “quantitative neuromuscular monitoring device” yields only a few companies competing with Senzime, including: TwitchView by Blink, Xavant, and GE Healthcare.

STANDARD OF CARE?

Are the 2023 ASA Practice Guidelines for Monitoring and Antagonism of Neuromuscular Blockade now a standard of care for practicing anesthesiology?

No. Guidelines are not Standards.

In these 2023 Practice Guidelines, the ASA states, “Practice guidelines are systematically developed recommendations that assist the practitioner and patient in making decisions about health care. . . . practice guidelines developed by the American Society of Anesthesiologists are not intended as standards or absolute requirements, and their use cannot guarantee any specific outcome.”

Expect quantitative NM monitors to become available where you work. Expect most hospitals to purchase these devices. What will you do until quantitative NM monitors become available where you work?

1. Since clinical assessment alone to avoid residual neuromuscular blockade is inaccurate, I believe a qualitative NM monitor is better than no NM monitor.

Qualitative Twitch Monitor

2. Monitoring twitch at the adductor pollicis at the wrist is more accurate than monitoring the periocular muscles, so apply your qualitative twitch monitor to the wrist.

3. Have sugammadex available when using non-depolarizing muscle relaxants such as rocuronium or vecuronium. If a patient shows signs of residual NM blockade at the end of an anesthetic, 2 mg/kg of IV sugammadex will usually resolve the NM blockade within a minute or two. Sugammadex, for the reversal of rocuronium-induced NM blockade, is one of the biggest advances in the field of anesthesiology in the past 10 years.

4. Following a general anesthetic, don’t leave your patient’s side in the PACU until you are certain that their airway is open and they are breathing adequately without any sign of residual respiratory difficulty.

Until your hospital and your surgery centers supply you with quantitative neuromuscular EMG monitors, be aware of the recommendations of the 2023 ASA Practice Guidelines for Monitoring and Antagonism of Neuromuscular Blockade, and comply with them as best as you can. When quantitative NM units arrive, I encourage you to use them. The device I tested was quick to apply, easy to use, and provided valuable information to assure patient wellbeing.

CIPROFOL VS  PROPOFOL

THE ANESTHESIA CONSULTANT

 

Ciprofol is a new intravenous (IV) anesthetic agent which is undergoing early clinical trials in China, and may become a significant tool in our anesthesia armamentarium if and when the drug is approved by the Food and Drug Administration (FDA) in the United States. Ciprofol has a chemical structure similar to propofol. Because of its rapid onset and rapid offset profile, propofol is currently the most used IV anesthetic drug in the world. Propofol is used for surgical anesthesia, procedural sedation, and intensive care unit (ICU) sedation. Propofol was FDA-approved in the United States in 1986 and is now off patent. Generic propofol is inexpensive, averaging about $2.27 for a 20 ml vial. Limitations of propofol include (a) respiratory depression, such that it can only be used by physicians who are expert in airway management (e.g. anesthesiologists, CRNAs, and emergency room doctors); (b) hemodynamic depression in some elderly or sick patients; (c) pain on injection; and (d) the propofol infusion syndrome (PIS) which can lead to hyperkalemia and cardiac arrest in ICU patients after prolonged exposure to propofol infusions.

The chemical formula of ciprofol is similar to propofol, but with single R-configured diastereoisomers.

Ciprofol is about 5 times more potent than propofol. Like propofol, ciprofol is formulated in a lipid emulsion with a drug concentration of 10 mg/mL. Let’s review the published literature on ciprofol to date. All of the following studies were done in China:

Phase 1 trials (small groups of subjects are given a single dose of the drug, and are observed and tested for a period of time to confirm safety):

Teng et al. (2021) conducted a phase I trial which demonstrated that a ciprofol dosing regimen of 0.4-0.9 mg/kg was well-tolerated and exhibited rapid onset and recovery properties. Peak plasma concentration occurred 2 minutes after injection, and all subjects recovered fully after ciprofol administration, with the shortest time being 9.2 minutes in the 0.4 mg/kg group.

Hu et al. (2021) also conducted a phase I trial in which subjects received continuous ciprofol or propofol infusions for up to 12 hours. The safety and tolerability of both drugs were comparable.

Phase II trials (performed on larger groups, e.g. 50–300 patients, to evaluate whether the drug has any biological activity or effect):

Teng et al. (2021) conducted a study on 1000 patients, which showed that ciprofol 0.4-0.5 mg/kg induced equivalent sedation/anesthesia to propofol 2.0 mg/kg during colonoscopy, and had a similar safety profile without producing serious adverse effects. No apnea was observed in any patients in the ciprofol group, but 5 patients in the propofol 2.0 mg/kg group experienced apnea. The incidence of injection pain was higher in the propofol group than in the ciprofol group (55% vs 6.8%). There were no significant dose-dependent changes in blood pressure in either the ciprofol or propofol groups.

Liu et al. (2021) conducted a phase II trial which involved 36 ICU patients who were on mechanical ventilation.  A remifentanil infusion of 0.02–0.15 μg·kg−1·min−1  plus either ciprofol or propofol were used for analgesia and sedation. The ciprofol loading dose was 0.1–0.2 mg/kg with a maintenance infusion rate of 0.3 mg/kg/h. The propofol loading was at 0.5–1.0 mg/kg, with a maintenance infusion rate of 1.5 mg/kg/h. The tolerability, sedation characteristics, and adverse events such as hypotension were comparable between both groups. The authors concluded that “ciprofol is comparable to propofol with good tolerance and efficacy for sedation of Chinese intensive care unit patients undergoing mechanical ventilation in the present study setting.”

The propofol infusion syndrome (PIS) is a potentially lethal syndrome that occurs due to prolonged infusion described in adults and pediatric ICU patients who are on mechanical ventilation. To date, published studies have not administered multi-day infusions of ciprofol to mechanically ventilated ICU patients to determine whether there is anything similar to PIS with ciprofol.

Wu et al. (2022) published a single-center trial on 92 patients titled “Efficacy and safety of ciprofol-remifentanil versus propofol-remifentanil during fiberoptic bronchoscopy.” Fentanyl (50 μg) was given to all patient 2 minutes before the intravenous administration of either 0.3 mg/kg of ciprofol or 1.2 mg/kg of propofol, followed by a remifentanil infusion in both groups. Top-up doses of one-third to one-fourth of the initial dose of ciprofol or propofol were repeated at 2-minute intervals as needed. The two drugs were comparable. The authors concluded that “ciprofol-remifentanil was non-inferior to propofol-remifentanil with regard to successful sedation for flexible bronchoscopy.” Systolic, diastolic, and mean blood pressures declined significantly less in the ciprofol-remifentanil group (p < 0.05). There was no difference in respiratory depression between the two groups, and the only statistical difference in adverse effects was a decrease in pain on injection for ciprofol over propofol (p=.001).

Chen et al. (2022) compared ciprofol and propofol in 120 women for the induction of anesthesia in gynecologic surgery. Intravenous midazolam (0.03 mg/kg) and sufentanil (0.3 μg/kg) were administered initially, followed by ciprofol (0.4 mg/kg) or propofol (2 mg/kg). After the loss of consciousness, rocuronium (0.6 mg/kg) was administered and endotracheal intubation was performed. Within the initial 10 minutes following study drug administration, blood pressure declined significantly less in the ciprofol group than in the propofol group. The authors concluded that “ciprofol was associated with slightly less pronounced effects on the cardiovascular system.” The incidence of injection pain was higher in the propofol group than in the ciprofol group (58% vs 16%, p < 0.001).

Chen et al. (2022) studied adverse reactions of ciprofol and propofol in 96 patients for gastroenteroscopy. Neither ciprofol nor propofol caused statistically significant differences in vital signs. The authors concluded that “in painless gastroenteroscopy, compared with propofol, ciprofol is equally safe and effective for patients.”

Lan et al. (2022) randomized 150 patients to ciprofol or propofol for hysteroscopy. All patients received intravenous sufentanil 0.1 μg/kg IV initially. Ciprofol patients then received an induction dose of 0.4 mg/kg and a maintenance dosage of 1.0 mg/kg/h. Propofol patients received an induction dose of  2.0 mg/kg and a maintenance dosage of 5.0 mg/kg/h. After the sedative administration, the systolic, diastolic, and mean pressures all  dropped significantly lower in the propofol group than in the ciprofol group. During the procedure, 2/75 ciprofol patients vs 17/75 propofol patients required an airway intervention such as a chin-lift or jaw-thrust maneuver (p< 0.05). The authors concluded that “the lower level of respiratory depression seen with ciprofol makes this drug more suitable and safer than propofol for hysteroscopic procedures.”

Phase III trials (randomized controlled multicenter trials on larger patient groups, aimed at determining how effective the drug is in comparison with the current “gold standard” treatment, i.e. propofol):

Li et al. (2022) conducted a phase III study at ten teaching hospitals, comparing ciprofol and propofol for deep sedation for colonoscopy or gastroscopy. A total of 289 patients were studied. Each patient received 50 μg fentanyl 1 minute before the intravenous infusion of either ciprofol (0.4 mg/kg) or propofol (1.5 mg/kg). Up to five top-up doses of 1/2 the initial dose were given upon signs of inadequate sedation, and repeated at 2-minute intervals as required. The mean time for a patient to become fully alert after the procedure was 3.3 minutes in the ciprofol group vs. 2.0 minutes for the propofol group (P < 0.001). The time to discharge was 7.4 minutes for the ciprofol group vs. 6.0 minutes for the propofol group (P < 0.001). Nine patients (6.3%) in the ciprofol group and 15 patients (10.3%) in the propofol group had respiratory events (respiratory depression, apnea, or hypoxemia), all of which were mild or moderate in severity. The authors concluded that “at a dose of 0.4 mg/kg for deep sedation, ciprofol was non-inferior to 1.5 mg/kg propofol in the success rate of gastroscopy and colonoscopy and exhibited a good safety profile.”

Wang et al. (2022) published a multi-center, double-blind phase III trial in which 186 surgery patients were randomly assigned to either ciprofol 0.4 mg/kg or propofol 2.0 mg/kg for the induction of general anesthesia. Ciprofol was “non-inferior” to propofol. Once again, the incidence of injection pain was significantly lower in the ciprofol patients compared to the propofol patients (6.8% vs. 20.5%, p < 0.05).

MY TAKE: WILL CIPROFOL BE A SUCCESSFUL ADDITION TO OUR IV ANESTHESIA DRUG ARSENAL?

It depends.

  • If ciprofol and propofol were cost-equivalent, ciprofol would gain some market share, and might prove to be a superior drug to propofol. However, when and if it is FDA-approved in the United States, ciprofol will cost significantly more than propofol because ciprofol will be on patent. Hospitals and surgery centers will be reluctant to pay more for the drug unless there are proven advantages. Ciprofol appears to have significantly less pain on injection when compared to propofol, but pain on injection with propofol is not a major issue. Pain on injection does not lead to any long term adverse outcomes, and the pain can be blocked by injecting IV lidocaine immediately prior the initial dose of IV propofol. 
  • The data that ciprofol leads to less blood pressure decreases than propofol shows only a mild difference—too small an advantage to mandate replacing propofol with ciprofol for that reason alone.
  • So far there are no data to confirm or deny that there is any equivalent to propofol infusion syndrome with ciprofol. If there is no prolonged infusion syndrome, then ciprofol may find a market for ICU sedation of mechanically ventilated patients.
  • Overall, I believe ciprofol must promise a lack of respiratory depression if the new drug is to capture any of propofol’s market share for procedural sedation/surgical anesthesia. The most bothersome issue with propofol is the risk of respiratory depression, which requires an anesthesia professional or airway expert administer the drug. If a patient is oversedated with propofol, that patient may stop breathing or have upper airway obstructed breathing, which can lead to hypoxia, cardiac arrest, and anoxic brain damage. The FDA warnings for propofol include:

For general anesthesia or monitored anesthesia care (MAC) sedation, DIPRIVAN Injectable Emulsion should be administered only by persons trained in the administration of general anesthesia and not involved in the conduct of the surgical/diagnostic procedure. Sedated patients should be continuously monitored, and facilities for maintenance of a patent airway, providing artificial ventilation, administering supplemental oxygen, and instituting cardiovascular resuscitation must be immediately available. Patients should be continuously monitored for early signs of hypotension, apnea, airway obstruction, and/or oxygen desaturation. These cardiorespiratory effects are more likely to occur following rapid bolus administration, especially in the elderly, debilitated, or ASA-PS III or IV patients.

In the Li study above6.3% of the ciprofol patients had mild to moderate respiratory adverse events when sedated for GI endoscopy. While the 6.3% rate is lower than the 10.3% rate for the propofol patients, the non-zero incidence of respiratory events with ciprofol in this one study points to an anesthesia professional still needing to be present if ciprofol is administered for endoscopy.

In the Lan study above, during IV sedation only 2/75 ciprofol patients, compared with 17/75 propofol patients, required airway intervention such as with a chin-lift or a jaw-thrust maneuver during hysteroscopy (p< 0.05). This lower incidence of required airway intervention is encouraging, but the incidence is still not zero, and we’ll need more data to document the respiratory risks of ciprofol.

If ciprofol sedation is found to NOT produce any significant respiratory depression, apnea, or upper airway obstruction (therefore less risk of hypoxia and anoxic brain damage), this would be a profound advance over propofol. Then ciprofol could be administered for procedural sedation, e.g. for gastroenteroscopy, without an anesthesia airway expert attending to the patient. There is insufficient studies to date to know whether this will be true or not.

My guess? After all the data is in, ciprofol will cause a non-zero incidence of respiratory depression, and therefore a non-zero risk of hypoxia and anoxic brain damage, so an anesthesia airway expert will be necessary to administer the drug. The advantage of ciprofol’s lower but non-zero incidence of required airway intervention will not be a major advance in the hands of anesthesia professionals. The higher cost of ciprofol will preclude the decision of hospitals and surgery centers to switch to ciprofol until the new drug is off patent.

We’ll have to wait for more data on ciprofol, but don’t be surprised if propofol remains on top of the intravenous sedative/hypnotic anesthesia drug pedestal after the studies are concluded.

THE ANESTHESIA CONSULTANT

The Department of Anesthesiology, Perioperative and Pain Medicine at Stanford has administered Mock Oral Board Exams to its residents twice yearly since the 1980s. The Mock Oral is designed to mimic the conditions of the American Board of Anesthesiology (ABA) Standardized Oral Exam (SOE), which candidates must pass to become board-certified. The reference article The American Board of Anesthesiology’s Standardized Oral Examination for Initial Board Certification provides an extensive summary of the oral board examination process. 

In a previous column I advised examinees how to best prepare for the Standardized Oral Exam, and how to best perform on the exam. In this column I’ll outline how to set up a Mock Oral Exam program.

The pass rate for the Standardized Oral Exam is approximately 88%.  By subtraction, about 12% of candidates fail the SOE. 

SOE (Standardized Oral Exam) pass rates for the American Board of Anesthesiology 2017 – 2021

I believe all candidates can benefit from taking Mock Oral Exams before they take the ABA test. I took my initial Mock Oral as a first-year resident in 1984 and I failed, botching the management of a difficult airway by performing a tracheostomy too soon. I took two Mock Orals each year after that and passed the ABA Oral Exam on my first attempt. I can attest that Mock Orals are an effective simulation to prepare for the ABA exam. One can search online and find books and prep classes to prepare for the Standardized Oral Board Exam, but the only way to rehearse verbal skills for an oral exam is take practice oral exams. It’s within the resources of every anesthesia residency program to provide Mock Oral Exams for their trainees. As an examiner I’ve administered Mock Oral Exams to over 100 residents since 1989. The recipe on how to set up such a program follows below:

SCHEDULING MOCK ORAL EXAMS

Assume a residency program has 10 residents in each year, for a total number of 30 residents. On three separate evenings in November, set up Mock Oral Exams for the first year, second year, and third year residents. Provide an equal number of examiners as you have examinees. Group the examiners in pairs and send each pair to a separate office room in your hospital headquarters. For example:

November 28th. First year resident exams from 1700 hours – 1735 hours, and from 1745 hours – 1820 hours. At 1700 hours the team of Faculty Member A and Faculty Member B will examine Resident Alpha. At the same time, in four adjoining rooms four other pairs of faculty members will examine four additional residents. At 1745 hours Faculty Member A and Faculty Member B will examine Resident Beta with the same exam question. The same format is followed in the four adjoining rooms, testing a total of ten first year residents. 

November 29th. Second Year Resident exams from 1700 hours – 1735 hours, and from 1745 hours – 1820 hours. The same staffing as November 28th is repeated. The examiners may be different. The exam questions are more difficult, given that the residents are one year further in their training.

November 30thThird Year Resident exams from 1700 hours – 1735 hours, and from 1745 hours – 1820 hours. The same staffing as November 28th is repeated. The examiners may be different. The exam questions are more difficult than on November 28th or 29th, given that the residents are in the last year of their residency training.

In May of the same academic year the exam sequence as above is repeated, giving each resident their second Mock Oral in the same training year. Each Mock Oral Exam lasts 35 minutes. The first 25 minutes will be questions about a hypothetical patient. The first examiner (e.g. Faculty Member A) begins by asking 10 minutes of questions dealing with preoperative anesthesia issues, followed by 15 minutes of questions about intraoperative issues by the second examiner (e.g. Faculty Member B), and in the final 10 minutes Faculty Member A asks questions about three completely different patients with assorted anesthesia dilemmas. 

SAMPLE MOCK ORAL TEST STEM:

An example of a Second Year Resident Mock Oral Board stem follows:

A 50-year-old man with hypertension, diabetes, obesity, and obstructive sleep apnea presents for an emergency surgery for a small bowel obstruction. He has been vomiting and unable to eat or pass gas for 12 hours. He has 8/10 pain in the abdomen. His medications are hydrochlorothiazide for hypertension, last taken 24 hours prior to admission, and a continuous insulin pump which he stopped 10 hours ago. He is 5 feet 6 inches tall and weighs 100 kg for a BMI=35. His pulse=120 beats per minute, blood pressure=170/105, oxygen saturation on room air=96%, respiratory rate=24 breaths per minute, and temperature=98.6. 

Physical exam: He is doubled over in abdominal pain and looks exhausted. His airway shows a thick neck circumference of 18 inches and a full beard. Except for tachycardia he has normal cardiac and lung exams. His abdomen is distended, and he has rebound abdominal tenderness and hyperactive bowel sounds. His labs are normal except for a glucose = 455 mg/dL and a potassium = 3.0 mEq/L. His ECG shows normal sinus rhythm. His chest X-ray is normal.

The script given to Faculty Member A reads as follows:

10 MINUTES – INTRAOPERATIVE MANAGEMENT 

  1. Blood glucose. How would you manage his blood glucose level? What would be your target glucose concentration? How would you administer insulin? How do you administer U-100 insulin? How would hypoglycemia present during general anesthesia? 
  2. Monitoring. Does this patient require invasive monitoring? Would you place an arterial line prior to induction? Why?  Is a CVP necessary? Why or why not? Would you use a pulmonary artery catheter? What about TE echo?
  3. Airway management. How would you manage the airway? Would you do an awake intubation? How would you do this? Would you do a rapid sequence induction? Which muscle relaxant would you use? Why? Assume you do a rapid sequence induction and you cannot see the vocal cords. What do you do? What if  you cannot intubate the patient and you cannot ventilate the patient with a mask?
  4. Potassium management. Will you administer potassium? Why? How fast would you give potassium? What are the risks of a low potassium during anesthesia? What are the risks of a high potassium concentration during replacement?
  5. Choice of anesthetic. What will be your plan for anesthetic maintenance? What are the advantages of inhaled anesthesia? Of total intravenous anesthesia? Which would you choose and why? Is there a role for regional anesthesia for this case? Why or why not?

The script given to Faculty Member B reads as follows:

15 MINUTES – POSTOPERATIVE MANAGEMENT 

  1. Extubation. Would you extubate the patient following the surgery? What would be your criteria for extubation? You decide to extubate the patient in the operating room. Immediately following extubation, his oxygen saturation falls to 80%. What is your differential diagnosis? How would you manage the situation?
  2. Arrythmia. On arrival to the ICU the patient’s heart rate increases to 150. How would you evaluate? Assume the blood pressure is 110/70. What therapeutic measures would you take? Assume blood pressure is 70/40. What therapeutic measures would you take?
  3. Oliguria. Assume the cardiac status is stabilized. The patient makes 80 ml of urine over the first two hours postoperatively. What is your differential diagnosis? What tests could you order? Why? Would you give a fluid bolus? Would you give a diuretic? Why? 
  4. Chest pain. Assume the patient is extubated on arrival to the ICU. He complains of upper abdominal/mid chest pain. How would you evaluate? What is your differential diagnosis? What tests would you order? How would you manage the situation?
  5. Postoperative pain. Assume no heart abnormalities are found. The patient is complaining of abdominal pain after surgery. How would you manage pain control? 

The final script for Faculty Member A reads as follows:

10 MINUTES – ADDITIONAL TOPICS 

  1. Pediatric open eye, full stomach. A 5-year-old child presents with an open eye injury due to a fall against a sharp table corner. She needs emergency surgery to save her eyesight. She ate a McDonalds Happy Meal two hours ago, but the ophthalmologist says the surgical repair cannot wait. The child will not let you start an IV while she is awake. How would you induce anesthesia? Would you consider a mask induction? Would you consider an intramuscular induction? How would you deal with the full stomach? How would you proceed? The child vomits during induction. How would you manage this?
  2. Morbidly obese patient for C-section. A 30-year-old woman presents in labor at 39 weeks. She is morbidly obese with a BMI=42. Her obstetrician decides the patient needs an urgent Cesarean section because of late decelerations on the fetal heart monitor. Would you choose regional anesthesia or general? Why? You attempt to place an epidural but get a wet tap. What would you do? If you had to administer a general anesthetic, how would you proceed?
  3. Family history of malignant hyperthermia. A 17-year-old boy with a tonsillar abscess presents for tonsillectomy. His uncle had a history of dying from malignant hyperthermia after tonsillectomy. Is this case appropriate for a freestanding outpatient surgery center? Would you delay the case? Would you order any preoperative tests? The surgeon says the case is urgent. What is your anesthetic plan?

At the conclusion of the 35-minute Mock Oral exam, the two examiners will stop. At this time the examiners discuss the performance with the resident examinee. This conversation includes:

  1. Asking the resident how they felt they did. 
  2. Discussing whether the resident made any anesthetic decisions that were unsafe, i.e. made the patient’s condition worse, or that led to a poor outcome.
  3. Discussing whether the resident answered the questions by describing what he or she would do. (This is the key to succeeding in oral examinations.)
  4. Discussing the resident’s communication and presentation skills, i.e. did they have effective eye contact, a confident speaking tone, and acceptable body language?
  5. Discussing whether the resident projected a fund of knowledge acceptable for their level of training.

Advice to Faculty Examiners on how to best perform a Mock Oral Exam:

  1. If you know the examinee personally, conduct the exam as if this was the first time you’d met them, i.e. they are “Dr. Examinee,” not “Justin,” or “Jennifer.”
  2. Read each question within the stem to the examinee, and listen to how they answer. Your job is to assess the examinee’s expertise in managing challenging anesthesia circumstances. If their answer is correct, quickly move on to the next question so you can test them on a new aspect of the patient care.
  3. Anytime an examinee introduces a new drug or a new test or a new fact into their answer, consider digging deeper by asking, “What is _____? What do you know about ____?”
  4. Don’t give immediate feedback after an answer by saying “OK.” Don’t reveal correct answers to the examinee during the exam.
  5. The examinee should not be asking you questions. If you are asked a question, deflect it by re-asking your previous question.
  6. Interject unexpected complications into each patient management, e.g. the blood pressure rises markedly or falls markedly, the pulse rate rises markedly or falls markedly, the oxygen saturation falls markedly. Find out what the examinee’s answer is in terms of differential diagnosis of the cause, and what their action(s) would be to correct the complication.
  7. Evaluate whether the examinee manages anesthesia and complications safely.
  8. Include a management of a difficult airway situation. The quickest way for an examinee to fail an oral exam is to lose an airway. 
  9. The purpose of the three extra cases in the last 10 minutes of the exam is to assess the examinee’s performance in areas that weren’t covered by the stem question, i.e. to round out the examination of pediatric, neuro, obstetric, cardiothoracic, pain, or regional anesthesia knowledge.
  10. Pay attention to the examinee’s body language, their eye contact, the confidence of their verbal answers, and their fund of medical knowledge. Does the candidate speak and answer like a consultant in anesthesiology would?

The University of North Carolina Department of Anesthesiology also administers twice yearly Mock Oral Board Exams. They videotape each exam so that each resident’s performance can be reviewed at a later date. 

Image from a videotape of Mock Oral Exams at the University of North Carolina Department of Anesthesiology

Writing Mock Oral Questions is not difficult. Performing the role of an examiner is not difficult. Prior to the exam, faculty examiners can look up the answers after reading through the questions, if they don’t know that specific area of anesthesia knowledge. 

Beyond the role of faculty members providing a Mock Oral Exam program, it’s also possible for examinees to prepare and give Mock Oral Exams to each other on their own time, as an opportunity for practicing and honing their verbal answering skills.

I recommend a Mock Oral Exam program as a key step toward passing the ABA Standardized Oral Exam, and toward becoming a board-certified consultant.

 in our field. As stated above, the only way to rehearse the verbal skills necessary for an oral exam is take practice oral exams. Good luck!

AUDIT TRAILS = THE BIG BROTHER OF MEDICAL CARE

THE ANESTHESIA CONSULTANT
The Audit Trail in the Electronic Medical Record

A spy lurks within every Electronic Medical Record (EMR), and most doctors have no idea that sentry exists. Every time a healthcare provider clicks his or her mouse on an EMR, that click is recorded by the Orwellian Big Brother of Medical Care, the audit trail. An audit trail can be defined as a “record that shows who has accessed a computer system, when it was accessed, and what operations were performed.” Virtually all EMRs in the United States now track at least four pieces of information about every instance a healthcare provider accesses a patient: 

  1. Who accessed, 
  2. Which patient record,
  3. At what time, and 
  4. The action they performed. 

The audit trail is NOT part of the EMR printout, and it’s not visible on the EMR patient care screen that we healthcare providers see. Lawyers can subpoena the audit trail in malpractice legislation, and the hospital must provide the audit trail if the court decides that the audit trail is relevant. An audit trail will look like an Excel document, with the provider’s name in one column and the information about each click listed in other columns:

In any malpractice legislation, an attorney will most likely have to hire an expert to interpret this audit trail for the judge and jury to understand what the document illustrates.

The audit trail was mandated by the 2005 Security Rule of the Health Insurance Portability and Accountability Act (HIPAA), which required all healthcare organizations to “implement hardware, software, and/or procedural mechanisms that record and examine activity in information systems that contain or use electronic protected health information.”  Any organization that works with electronic protected health information—which includes patient names, addresses, social security numbers, and other pieces of sensitive personal information—must use audit trails. The purpose of the audit trail was to detect inappropriate viewing of the EMR by someone who was not directly caring for the patient. For example, preventing a healthcare provider from clicking on the EMR of someone else’s patient who is a neighbor, a previous girlfriend, a celebrity athlete, politician, or entertainer. But an audit trail is a roadmap to a physician’s EMR use, and in the case of a malpractice lawsuit, the audit trail can be either redeeming or damning.

Back in the era of handwritten medical records, Samuel Shem described “buffing the chart” in his medical satire novel “The House of God.” 

“Buffing the chart” was a dishonest means of writing medical notes in a patient’s chart to make the patient look well-treated, without the doctor providing that treatment. Buffing the chart, or any other dishonesty, is impossible with EMRs. The audit trail will document whether you provided standard medical care in real time or not. If your patient has a significant complication or an adverse outcome, a lawyer can subpoena the audit trail and hire an expert to interpret it. 

Indeed, the most common use of audit trails is in medical malpractice actions. Let’s look at some hypothetical examples:

  • A 36-year-old woman is scheduled for emergency surgery at 3 a.m. for an ectopic pregnancy. The patient weighs 250 pounds and is 5 feet tall, for a Body Mass Index (BMI) = 48.8. On induction of general anesthesia, the anesthesiologist working alone is unable to successfully place an endotracheal breathing tube and is unable to ventilate oxygen into the patient. The patient develops anoxic brain damage. The family sues the anesthesiologist, and the plaintiff attorney orders an audit trail. The audit trail documents that the anesthesiologist never clicked on an available old anesthetic record which documented that this patient had a difficult airway, in which it took two anesthesiologists twenty minutes to successfully insert an endotracheal breathing tube using both a GlideScope and a fiberoptic laryngoscope. The audit trail also documents that one day after the surgery, the anesthesiologist added a paragraph to his preoperative note claiming that he was aware of the previous difficult airway diagnosis. Once the audit trail results were revealed, the anesthesiologist and his defense lawyer realize that they cannot win, and they pay a malpractice settlement out of court.  
  • A 55-year-old man is scheduled for a left hip replacement. His past medical history is significant only for hyperlipidemia. The EMR shows standard of care anesthetic management for the surgery, but in the Post Anesthesia Care Unit (PACU) the patient develops shortness of breath, chest pain, and needs to be reintubated and sent to the Intensive Care Unit. Cardiologists diagnose an acute myocardial infarction (MI) and congestive heart failure. The patient survives, but the MI leaves the patient with reduced cardiac output and chronic heart failure. The patient sues, and the plaintiff attorney orders an audit trail. The audit trail reveals that the anesthesiologist never looked at the preoperative ECG which showed ischemic changes. The standard of care following this abnormal ECG required a cardiology consult prior to the elective surgery. The plaintiff wins the case as the anesthesiologist and the primary care doctor failed to make the required referral to a cardiologist prior to the hip surgery.
  • A 55-year-old patient on chronic dialysis is scheduled for revision of a left forearm dialysis fistula. The patient receives general anesthesia for the case and has a cardiac arrest mid-surgery. The patient’s family sues, and the plaintiff attorney orders an audit trail. The audit trail shows that the patient’s potassium level prior to surgery was markedly elevated at 8.1, and this lab value was available on the chart 30 minutes prior to the induction of anesthesia, and the anesthesiologist never clicked on the laboratory value to check what the result was prior to the surgery. The plaintiff wins the malpractice lawsuit.

The following are quotations from a legal review article titled “A Pandora’s Box: The EMR’s Audit Trail.”

  1. A subpoena for audit trail information must be for legitimate reasons.  
  2. There is no clear precedent currently on the issue of whether a defendant health care provider must produce an audit trail as a matter of standard course as if it were the medical record itself. Courts surprisingly are deciding the issue primarily on relevance grounds.
  3. Once the audit trail is produced and counsel has had a chance to review it to the care rendered, plaintiff’s counsel may seek to make an issue regarding the truthfulness of the information contained in the EMR at trial including allegations of alteration or wrongdoing.
  4. Simple conjecture or inferences that an EMR record was altered based on a review of the audit trail is not enough, and expert testimony to support that position may be required. Absent expert testimony, a plaintiff patient was not permitted to present evidence to the jury.

The following are quotations from a legal publication “The Utility of Audit Trails Analysis in Medical Malpractice Actions” :

  1. Each time a patient’s EMR is opened, regardless of the reason, the audit trail documents this detail. The audit trail cannot be erased, and all events related to the access of a patient’s EHR are permanently documented in the audit trail. Providers cannot hide anything they do with the medical record. No one can escape the audit trail. It’s easy to see how and why an audit trail could serve as an important piece of evidence in a medical malpractice action. 
  2. In printed form, [audit trails] can look like gibberish to the untrained eye. Fortunately, there’s a simple solution to these problems: the use of an expert trained in understanding and navigating EMR systems and interpreting and explaining audit trails.

The take-home message: the era of “buffing the chart” is over. Whenever we healthcare providers click on any item on the EMR, or whenever we don’t click on an item on the EMR, a Big Brother Audit Trail is watching and permanently recording who accessed the EMR, which patient item was accessed, at what time, and what action was performed.

THE ANESTHESIA CONSULTANT

Imagine this scenario: You’ve just finished anesthetizing a patient in a hospital setting, and the patient now requires transport from the operating room (OR) to the post-anesthesia care unit (PACU). During surgery your patient monitors included: a pulse oximeter, an ECG, a blood pressure cuff, a temperature monitor, and a monitor of the oxygen, carbon dioxide, and anesthetic concentration of every breath inhaled and exhaled. During the transport to the PACU, a trip which can be as short as 1 minute or as long as 5 minutes, there are no specific standards regarding monitoring. It’s common for zero monitoring equipment to be attached to the patient. It’s also not uncommon for the patient to be breathing room air during transport. When you arrive at the PACU, a nurse reattaches your patient to the vital sign monitors, and discovers that the patient’s oxygen saturation has dropped from 100% in the OR to a severely low value of 80% in the PACU. 

Patients can have inadequate breathing on arrival at the PACU for multiple reasons, including oversedation from narcotics, oversedation from propofol or general anesthetic gases, residual paralysis from muscle paralysis drugs, upper airway obstruction, laryngospasm, obesity, sleep apnea, or pulmonary disease. An anesthesiologist can easily make a diagnosis of inadequate breathing if a patient is connected to a pulse oximeter. Should we routinely monitor a patient’s oxygen saturation level during transport to the PACU?  Let’s examine current standards and policies regarding anesthesia patient transport and review the published incidence of inadequate oxygenation following OR to PACU transport.

The American Society of Anesthesiologists (ASA) Standards for Post-Anesthesia Care state: 

A PATIENT TRANSPORTED TO THE PACU SHALL BE ACCOMPANIED BY A MEMBER OF THE ANESTHESIA CARE TEAM WHO IS KNOWLEDGEABLE ABOUT THE PATIENT’S CONDITION.  THE PATIENT SHALL BE CONTINUALLY EVALUATED AND TREATED DURING TRANSPORT WITH MONITORING AND SUPPORT APPROPRIATE TO THE PATIENT’S CONDITION.”

This sounds like a reasonable standard, but it’s non-specific and leaves the decision regarding oxygen therapy and monitoring up to the individual member of the anesthesia care team’s judgment.

One the Harvard hospitals, Beth Israel Deaconess Medical Center, published the following policy regarding anesthesia transport:

Post Anesthesia Transport Monitoring 

After an anesthetic, the patient is usually transferred to the PACU or an ICU. This guideline sets out to clarify the type of patients who will need monitoring during transportation, and the nature of monitoring required. 

Monitoring during transport is mandatory for the following patients 

·  Any patient designated as needing ICU care, irrespective of whether the patient actually goes to the PACU or an ICU. 

·  Patients who are receiving vasopressors, vasodilators, or inotropes. 

·  Any patient who has a pulmonary artery catheter in situ.

·  All intubated patients. 

·  Any patient who has had an unstable course during the anesthetic. 

·  Any patient who needs to be transported for longer than 5 minutes to the recovery area.

The above list is not exhaustive and monitoring for transportation may be instituted for any patient at the discretion of the anesthesiologist. 

This is a reasonable policy, but what if anesthesia patient transport to the PACU lasts 4 minutes and 59 seconds (i.e. a long transport, but less than 5 minutes to the recovery area)?

The most common complications for in-hospital transported patients are respiratory, meaning that a patient has inadequate breathing and/or inadequate oxygen therapy during transport. The following five studies document that unmonitored patients frequently have low oxygen levels following transport to the recovery room.

In the 2012 study Does the transportation of patients from the operating room to the post-anesthetic care unit require supplemental oxygen? the authors prospectively looked at 50 patients transported from the OR to the PACU. They measured the oxygen saturation when each patient left the OR and when the patient arrived in the PACU. Moderate hypoxemia (oxygen saturation 86% to 90%) and severe hypoxemia (oxygen saturation less than 85%) occurred in 8% and 4% of patients, respectively. Seventy-five percent of the patients with moderate or severe hypoxemia were obese, and 42% were smokers. 

In the 2012 prospective study Hypoxemia after general anesthesia

959 patients underwent elective surgery under general anesthesia in a university hospital. All were transported to the PACU on room air without oxygen supplementation. The oxygen saturation level was measured at the end of the transfer to the PACU. Seventeen percent of patients had a pulse oximetry reading < 90%, and 6.6% had a pulse oximetry reading < 85%. The authors concluded that “transportation of patients breathing room air from the OR to the PACU directly after GA without use of PO or supplemental oxygen seems to be questionable in terms of patient safety.”

In the 2015 study, Impact of medical training clinical experience on the assessment of oxygenation and hypoxemia after general anesthesia: an observational study, anesthetists, nurses, and medical students estimated the oxygen saturation level in their patients at the end of transfer to the PACU, after the patients had been breathing room air during the transfer following surgery under general anesthesia. The estimated oxygen saturation level was compared to the actual oxygen saturation level measured by pulse oximetry. Low oxygen saturation (oxygen saturation < 90 %) occurred in 154 out of 1,138 patients (13.5 %). Anesthetists, nurses, and medical students accurately identified only 25, 23, and 21 of the 154 patients as being hypoxemic, respectively. The authors concluded that “considering the uncertainty about deleterious effects of transient, short-lasting hypoxemia, routine use of pulse oximetry is advocated for patient transfer to the PACU.”

In the 2016 study Predictors of desaturation during patient transport to the postoperative anesthesia care unit: an observational study13% of 505 patients had hypoxemia during transfer to the PACU. The three risk factors for low oxygen saturation were a Richmond agitation-sedation (RASS) score lower than -2, an oxygen saturation <96% before exiting the operating room, and a body mass index >30. Seventy-two percent of the patients were transferred without oxygen, and most of the hypoxemia appeared in these patients. The authors concluded that the development of hypoxemia during transfer from the OR to the PACU was greater in patients who were more sedated, obese, or had lower oxygen saturations when they left the OR. The authors also concluded that “supplemental oxygen should be considered in higher risk patients.”

In the 2020 study Complications associated with the anesthesia transport of pediatric patientsthe authors looked at a database of 2971 events pediatric adverse events, and 5% (148 events) were related to patient transport. The adverse events were primarily respiratory. Nearly 40% of the reported adverse events occurred in infants of an age less than or equal to 6 months. Seventy-five percent of the adverse respiratory events occurred postoperatively during transport from the OR to the PACU or the OR to the intensive care unit (ICU).

The distance from the OR to the PACU in the hospital I work at can be as much as 120 yards, and require anesthesia patient transport times of up to 5 minutes. The hospital supplies oxygen tanks on every gurney used to transport surgical patients from the OR to the PACU. The anesthesiologist administers nasal or mask oxygen to patients during transport.

Regarding respiratory monitoring during transport, a non-electronic monitor formerly utilized by anesthesiologists during patient transport was to pull a patient’s jaw toward the ceiling, with the palm of our hand of spanning across the patient’s mouth. In this manner we could feel each exhaled breath, documenting that the patient was breathing and ventilating themselves.

Since the arrival of COVID and the high risk of the spread of infection, anesthesiologists are wearing gloves whenever they are managing airways, and sensing a patient’s breathing through the thickness of the glove is ineffective. We need pulse oximetry monitoring.

to document adequate breathing and oxygenation. 

Every hospital owns portable vital sign monitors that look something like this:

portable vital sign monitor

These devices show real-time numeric values for the oxygen saturation, heart rate, ECG rhythm, and blood pressure, the same vital signs that are followed in the operating room. The acquisition cost for this monitor is currently $1300 per unit. If a hospital has 12 operating rooms, the total cost of 12 X $1300 = $15,600 is a reasonable investment to avoid patient complications of unstable vital signs during transport. 

What about a less expensive alternative? What about the inexpensive battery-powered pulse oximeters that clip over a fingertip are readily available at drug stores or on the internet. This product

$22.80 fingertip battery-powered pulse oximeter

is available on Amazon for $22.80, and has been reviewed by over 200,000 individuals to date. I bought one for my home and use it whenever a family member has respiratory viral symptoms. If a hospital stocked inexpensive oximeters like this one, doctors and nurses could diagnose low oxygen saturation in their patient(s) within seconds. Would these small portable devices begin to disappear or get lost? Perhaps. A possible solution would be to assign a fingertip pulse oximeter to each physician or nurse who has a need for one, and to expect them not to lose their own personal device. Could continuous fingertip pulse oximetry prevent hypoxic events during in-hospital transports? Yes. A prospective study testing this practice would be easy to do. The connection of fingertip monitors to a hospital’s electronic medical record (EMR) would not be practical, but the purpose of the monitor is to keep patients safe. Whether the monitor readings are recorded in a vital sign readout of the EMR is a less important factor. 

In conclusion, the post-surgical transport of a patient from the operating room to the PACU is a period of patient risk. The routine use of supplemental oxygen and the routine use of pulse oximetry can help anesthesiologists decrease this risk of inadequate breathing and low oxygen saturation during transport. 

CODA: The transport of post-operative patients from the OR to the ICU is a more complex undertaking than transport of patients from the OR to the PACU. The distances between the OR and the ICU are greater than the distance between the OR and the PACU. The ICU may be on a different floor and necessitate an elevator ride. A patient bound for the ICU may be asleep and intubated, which requires the anesthesiologist to ventilate the lungs with an Ambu bag attached to the endotracheal tube during the transfer. The patient may be requiring infusions of vasoactive drugs to maintain blood pressure within safe limits. The anesthesiologist may be supervising the transfusion of blood, platelets, or plasma. Managing all these factors while vigilantly watching the monitor screen while riding in an elevator with a sick patient is a challenging experience. Indeed, the post-surgical transport of a patient from the OR to the ICU requires an anesthesiologist to manage a rolling intensive care unit experience.

ANESTHESIOLOGY VS. DERMATOLOGY

THE ANESTHESIA CONSULTANT

Dermatology and anesthesiology are two medical specialties which offer lifestyle balance. Dermatology is consistently one of the most competitive residencies for graduating medical students. In a ranking of the most competitive medical specialties, dermatology ranked second, trailing only plastic surgery.  Dermatology was also ranked as the number-one specialty in terms of work-lifestyle balance. Dermatology is a high-paying medical specialty with almost no emergencies, weekend duties, or night call. Dermatologists can take weeks off work without losing their entire practice. Dermatologists perform procedures with their hands, including biopsies or the resection of lesions. Dermatologists have important roles treating common problems such as chronic acne or diagnosing life-threatening melanomas. Dermatology clinic is known for short visits and long lists of patients. If a patient has multiple medical comorbidities such as hypertension, heart problems, obesity, or sleep apnea, these issues are usually unrelated to the dermatology consultation. Hypertension, heart problems, obesity, and sleep apnea are problems for the patient’s internal medicine doctor, not for the dermatologist. A career in anesthesiology seems markedly different than a career in dermatology, because anesthesiologists frequently deal with acutely ill patients, middle of the night emergency surgeries, and complex anesthetics for open heart, brain, or neonatal surgeries. But one large subset of anesthesia work closely mimics the lifestyle of dermatology practice. Before you sign up for a lifetime as a dermatologist, consider the subspecialty of ambulatory anesthesiology.

Ambulatory anesthesiology is defined as the administration of anesthetics for outpatient surgical procedures, which are minor procedures which don’t require hospitalization. Most anesthetics in the United States are for ambulatory surgeries. In 2014 there were 11 million outpatient surgeries, which was 52% of the total number of surgeries. Outpatient surgeries include tonsillectomy, knee arthroscopy, shoulder arthroscopy, breast biopsy, hernia repair, rhinoplasty, hand surgery, foot surgery, nasal septoplasty, colonoscopy, and upper gastrointestinal endoscopy. These procedures are low-risk surgeries which don’t disturb a patient’s physiology in any significant way. Ambulatory surgery patients are prescreened to eliminate those with medical problems such as morbid obesity, severe sleep apnea, or unstable cardiac, respiratory, or neurologic diagnoses. An anesthesiologist practicing 100% in an ambulatory surgery center should have zero emergency anesthetics, zero weekend duty, and zero night call. 

The duration of training for an anesthesiologist and a dermatologist is identical. Both specialties require four years of college, four years of medical school, a one-year medical internship, and three years of residency training. For either specialty, if you graduate high school at age 18, you’ll be at least 30 years old when you finish training and are ready to begin your career. A significant amount of deferred gratification is required for both specialties. Your friends who went to work straight out of college will be at least eight years ahead of you in the game of life, and may have already accumulated a mortgage and 1.93 children during the years you’ve been working as a resident physician and memorizing massive quantities of medical knowledge. Anesthesia will never be as safe or predictable as dermatology.  Anesthesia residents are required to manage all forms of cases, including open-heart surgeries, neurosurgeries, trauma surgeries, Cesarean sections, and emergent chest or abdominal surgeries. Major complications are rare in outpatient anesthesia, but if one is inducing general anesthesia, then unexpected complications of airway, breathing, or circulation (the ABCs) can occur.

Both dermatology and anesthesiology are high-paying specialties. See the list below. The average salary for a dermatologist is $438,000 (7thhighest of all specialties), and the average salary for an anesthesiologist is 405,000 (11th highest of all specialties). 

Samuel Shem’s classic medical satire “The House of God,” followed a cadre of burned-out internal medicine residents through their internship year. At the end of the book, the residents reached the conclusion that their best futures were in the NPC—Non-Patient Care—specialties, which numbered six and only six: Rays, Gas, Path, Derm, Eyes, and Psych, that is: radiology, anesthesiology, pathology, dermatology, ophthalmology, and psychiatry. The main character in “The House of God” switched his specialty from internal medicine to psychiatry. In my career I switched from internal medicine to anesthesiology. Anesthesiology is not truly a “Non-Patient Care” specialty. Anesthesiologists very much care for patients every day. A key difference is that anesthesiologists care for each patient for a short and finite time. We don’t have to deal with a patient’s chronic problems over many years, as their internal medicine doctor must do. 

An experienced anesthesiologist may eventually land a fulltime job at an ambulatory surgery center (ASC), and at that point he or she may confine his or her career to a stable weekday life of outpatient surgeries, but this ascension to ambulatory-only anesthesiologist is not common. Most career anesthesiologists who practice in ambulatory surgery centers also continue to practice at a hospital. Most general anesthesiologists need to master both inpatient and outpatient surgeries.

Is it possible to jump directly from the completion of an anesthesia residency to a solely ambulatory practice, thus mimicking the lifestyle of dermatology? In the past, I’d say the answer was no. In recent years the lack of an adequate number of anesthesiologists has created a supply-demand situation in which outpatient surgery centers have insufficient numbers of anesthesiology staff. In some geographic markets, outpatient surgery centers may choose to hire young residents right out of training. I direct you to the recent employment ad below, which promises a salary of $385,000 to $4000,000 per year for an ambulatory anesthesiology job with “No nights, weekends, holidays, trauma, hearts, neuro or OB.”

If you’re interested in a quality lifestyle medical career with regular hours, weekends off, and few emergencies, add the option of ambulatory anesthesiologist to your list of possible choices. But to gain entrance to the Emerald City of ambulatory anesthesiology, you’ll have to walk a Yellow Brick Road through a challenging anesthesia residency first. In all probability, you’ll spend your early career doing some inpatient emergency anesthesia as well. But an eventual career in ambulatory anesthesiology is an outstanding option in which you can anesthetize patients on a  weekday schedule, spend weekends and evenings with your family, and turn the ringer off on your cell phone when you go to sleep at night.

HOUSE OF THE DRAGON BLOODY CESAREAN SECTION: A DOCTOR’S PERSPECTIVE

THE ANESTHESIA CONSULTANT

(SPOILER ALERT – CONTAINS PLOT REVELATIONS FROM HOUSE OF THE DRAGON, SEASON 1 EPISODE 1) Twenty million people tuned in to watch the first week of HBO’s House of the Dragon (the Game of Thrones prequel). The first episode contained a gory scene of an awake Cesarean section. Queen Aemma was in the process of giving birth to a male heir, the baby was presenting feet first (breech), and was stuck,and could not be delivered vaginally. Grand Maester Mellos (a medieval physician-equivalent) offered a potential solution to the king. He said, “During a difficult birth, it sometimes becomes necessary for the father to make an impossible choice. To sacrifice one, or to lose them both. There is a chance that we can save the child. A technique that is taught at the Citadel—which involves cutting directly into the womb to free the infant. We must either act now or leave it with the gods.” Soon after that conversation a knife descended as Mellos cut into the queen’s abdomen while she screamed and the king whispered into her ear that he loved her. The blood loss from the procedure left the queen dead from hemorrhagic shock. On the day following the broadcast, social media erupted at this non-consensual torture waged against the mother.

From a doctor’s perspective, could this fictional scene really have happened centuries ago? It’s a fact that cutting a child out from his mother’s womb was a death sentence for the mother in an era prior to the discovery of anesthesia and prior to the discovery of surgical techniques to control bleeding and infection. In the real history of our world, it’s unlikely any husband or family was offered the choice whether to sacrifice the birthing mother to save the child. Most Cesarean sections were done because the mother was already dead and cutting into the womb was a last gasp measure to save the child’s life. As House of the Dragon depicted, in primitive times there was no way to stop the acute bleeding from Cesarean incisions into the abdomen and the uterus. 

Cutting a child out from the uterus has been called a Cesarean section for centuries. Julius Caesar himself was not born from the procedure, as his mother did not die during his childbirth—she lived until Caesar’s mid-40s.  Cesarean section did have a significant role in a Shakespeare tragedy other than Julius Caesar.  In Shakespeare’s Macbeth the witches’ prophecy was that “. . . none of woman born/ Shall harm Macbeth.” (Act IV. Scene i) The Scottish nobleman Macduff was “from his mother’s womb/ Untimely ripped.” (Act V. scene vii) That is, Macduff was born by Cesarean section, and not naturally born of woman. Macduff eventually killed Macbeth in battle. 

The first known Cesarean section in which both the mother and child survived was performed in Prague in 1337.  The first successful Cesarean section to be performed in the United States took place in Virginia in 1794. Nonetheless, in Great Britain and Ireland in 1865 the mortality for Cesarean section was 85%. 

The medical advances that enabled nearly all women to survive Cesarean section were: 1) the discovery of sterile surgical practices of handwashing and antisepsis to prevent postoperative infections; 2) the discovery of surgical techniques to stop bleeding; and 3) the discovery of anesthesia.

Sterile surgical procedures began when Dr. Ignaz Semmelweis, a Hungarian physician, noted in 1847 that fewer women died from post-surgery fever if surgeons washed their hands. Years later Dr. Louis Pasteur and Dr. Joseph Lister provided evidence to explain germ theory. Dr. Lister’s principles of antiseptic care led the way to asepsis, which was the complete elimination of bacteria during surgery. 

Until the 1870s Cesarean section surgical technique to control bleeding remained crude, and did not include surgical suture closure. In 1882 the German obstetricians Dr. Adolf Kehrer and Dr. Max Sänger developed methods for preventing uterine bleeding by using suture (stitches) to close the wound

Prior to the discovery of general anesthesia, sedation for surgery usually included oral alcohol drinks, or opiates derived from poppies. General anesthesia was discovered in October 1846, when Dr. William Morton gave a public demonstration of inhaled ether use at the Massachusetts General Hospital in Boston. One year later, James Simpson, a Scottish obstetrician, administered ether to relieve the pain of childbirth for a woman with an abnormal pelvis. In 1853 Dr. John Snow gave Queen Victoria the inhaled anesthetic chloroform to relieve labor pain during the birth of her eighth child.

A modern Cesarean section is most often done under a spinal or epidural anesthetic. The anesthesiologist injects a local anesthetic drug into the mother’s low back to render her numb from the level of her nipples to her toes. Under this regional anesthetic, a mother can be awake to bond with her infant minutes after the child is born. In emergency circumstances, general anesthesia may be required for Cesarean section. In these situations, a general anesthetic drug such as propofol is injected into the mother’s intravenous line, rendering her unconscious within 20-30 seconds. The anesthesiologist then inserts an endotracheal breathing tube into the mother’s windpipe (trachea) to ensure that oxygen and anesthesia gases are delivered directly and safely into the lungs, and at the same time eliminating the risk of stomach contents regurgitating into the mother’s lungs.

In the United States today, Cesarean deliveries comprise a stunning 1/3 of the total number of births. Attempts to reduce the rate of Cesarean sections have been largely unsuccessful because of the perceived safety of the operation, the medical-legal climate, and maternal requests for Cesarean sections. Cesarean sections carry a higher maternal mortality risk compared with vaginal birth. In a retrospective study of 1.5 million deliveries between 2000 and 2006, the rate of maternal death was 0.2 per 100,000 for vaginal births, and 2.2 per 100,0000 for Cesarean deliveries.  

Cesarean sections in the United States today are typically controlled surgeries, with comfortable mothers and with the father present in the operating room holding the mother’s hand. Expectant mothers can be reassured that because of advances in anesthesia and surgery, the pain, horror, and lethal outcome from a Cesarean section as depicted in the House of the Dragon will not occur in the modern world of medicine.

There are hundreds of anesthesia textbooks, but which current books are the gold standards for anesthesia knowledge? Should you buy these books, or should you advocate that your hospital purchase them for the medical library? When I was in residency training, I bought earlier editions of many of these textbooks so I could underline and highlight pertinent pages. If you purchased all 11 books in a print version today it would cost $1,643.49. The twenty-first century is a digital age, and if you purchased all 11 books in an ebook version today it would cost slightly less, at $1453.00. I currently have access to these ebooks through Stanford University’s Lane Medical Library, and I read them remotely through the Lane Library’s online website. I’ve come to prefer to read a digital copy over a hardcover book. A digital copy of a textbook is easy to access, easy to search keywords, and it’s convenient to print out excerpts or chapters. A digital textbook collection is portable, and can travel with you in your laptop, your phone, or your tablet. Digital access to all this written expertise can be at your fingertips anywhere, including in the operating room suite.

THE ANESTHESIA CONSULTANT

JAMA Surgery published the study Association of Anesthesiologist Staffing Ratio With Surgical Patient Morbidity and Mortality on July 22, 2022. This was a landmark paper on the topic of anesthesiologist:CRNA staffing ratios, which documented that having physician anesthesiologists direct three or four operating rooms simultaneously for major noncardiac inpatient surgical procedures increased the 30-day risks of patient morbidity and mortality. The senior author was Sachin Kheterpal, MD, MBA, of the Department of Anesthesiology at the University of Michigan Medical School. The data was from a retrospective matched cohort study of major noncardiac inpatient surgical procedures performed from January 1, 2010, to October 31, 2017, and was conducted in 23 academic and private hospitals in the United States. 

The University of Michigan paper stated, “this study primarily analyzed physician-CRNA teams, the dominant practice model in US anesthesiology.” The physician-CRNA team, otherwise known as an anesthesia care team, is a model strongly supported by the American Society of Anesthesiologists.  The anesthesia care team is a system in which one anesthesiologist covers one, two, three, or four separate operating rooms, each room staffed by a Certified Registered Nurse Anesthetist (CRNA) or an anesthesia assistant (AA). From a very large initial data set of 3,624,399 operations, the University of Michigan authors calculated the staffing ratio of physician anesthesiologist: CRNA for each operation. The following types of cases were excluded: anesthesia care personally performed by a physician anesthesiologist working alone; anesthesia care which involved an anesthesia assistant; anesthesia care involving an anesthesia resident; and anesthesia care that occurred overnight, during weekends, or on holidays. After these exclusions were applied, the data set consisted of 866,453 operations, in which 1960 anesthesiologists provided care in 23 different hospitals.

Data was divided into four groups:

  • Group 1: one anesthesiologist covering one operation (48,555 patients)
  • Group 1-2 (reference group): one anesthesiologist covering more than one to no more than two overlapping operations (247,057 patients)
  • Group 2-3: one anesthesiologist covering more than two to no more than three overlapping operations (216,193 patients)
  • Group 3-4: one anesthesiologist covering more than three to no more than four overlapping operations (67,010 patients)

The four groups were studied regarding 30-day morbidity and mortality outcome data. The morbidities included cardiac, respiratory, gastrointestinal, urinary, bleeding, and infectious complications. Overall, morbidity and mortality occurred after 30,026 operations (5.19%).

The results:

Compared with patients in group 1-2, those in group 2-3 had a 4% relative increase in mortality and morbidity (5.06% vs 5.25%; P = .02). 

Compared with patients in group 1-2, those in group in group 3-4 had a 14% increase in risk-adjusted mortality and morbidity (5.06% vs 5.75%; P < .001).

The paper stated, “When 100,000 operations, which is typical annually for a major medical center, are considered, the increase in risk from 5.06% to 5.75% that we observed would translate to an additional 690 operations with adverse outcomes,” and “increased overlapping anesthesiologist coverage beyond 1 to 2 operations was associated with an increased risk of surgical patient morbidity and 30-day mortality. Because 313 million surgical procedures are performed worldwide each year, any small individual improvements in outcome can have major repercussions for public health. These results complement previous studies that have shown improved 30-day mortality and morbidity rates after complications when anesthesiologists directed anesthesia care.”

The results of this study may be criticized because the data was retrospective, but it’s unlikely any prospective study will ever be done randomizing major noncardiac inpatient surgeries to anesthesiologist:CRNA ratios of 1:1, 1:2, 1:3, and 1:4. The adoption of Electronic Medical Records (EMRs) brought on the arrival of Big Data such as in this paper, in which a Herculean total of over 3.6 million charts were studied. An EMR enables physicians to study trends and outcome data in ways that were previously impossible. Does the data from the University of Michigan study support the fact that decreased staffing by physician anesthesiologists in major noncardiac inpatient surgical procedures is associated with increased 30-day morbidity and mortality? Yes, it does. Will this conclusion change the future practice of anesthesiology? Perhaps, but probably not. Why not? Let’s examine the most likely reasons behind the increased anesthesiologist:CRNA staffing ratios:

  1. There may be an inadequate supply of physician anesthesiologists to staff all major noncardiac inpatient surgical procedures at anesthesiologist:CRNA ratios of 1:1 or 1:2. There were 31,130 anesthesiologists in the United States in 2021, and more than 55,000 CRNAs in the United States. There were approximately 21 million surgeries per year in the United States in 2014.   The ratio of the number of surgeries compared to the number of anesthesiologists (21,000,000/31,130) equals 675 surgeries per anesthesiologist, a busy caseload. But the geographical distribution of where anesthesiologists live is not random, with populations of MD anesthesiologists concentrated in urban and suburban areas, and populations of MD anesthesiologists less concentrated in rural areas. Some locations have an inadequate census of physician anesthesiologists to staff every case as solo practitioners or at an anesthesiologist:CRNA ratio of 1:1 or 1:2. 
  2. A higher anesthesiologist:CRNA ratio may be a strategy to decrease the cost of anesthesia care. This issue was examined in detail in the American Society of Anesthesiologists Monitor.  In this study, the reported average yearly salary for a CRNA was $202,000, and they worked 40 hours per week. The reported average yearly salary for a private practice anesthesiologist was $440,000, and they worked 55 hours per week.  Cost-analysis showed that with adequate numbers of CRNAs to staff anesthesia care teams and to cover breaks for working CRNAs, the anesthesiologist:CRNA ratios of 1:2 and 1:3 were actually more expensive than running the rooms with a solo anesthesiologist in each room. An anesthesiologist:CRNA ratio of 1:4 was only marginally (< 10%) less costly than running the rooms with a solo anesthesiologist in each room. 
Figure 3: 7 a.m. to 5 p.m. with break staff included. Because one needs 1.25 CRNAs per site to cover the 10-hour shifts, the cost savings for anesthesia care team model is further reduced. Anesthesia care team costs are compared to physician-only (MD-only). Spikes in costs are when the number of sites cannot be divided by the staffing ratio. 

3. A high anesthesiologist:CRNA ratio may increase the income per anesthesiologist. When one anesthesiologist directs multiple CRNAs in multiple operating rooms, that solitary physician anesthesiologist can increase his billing for the day. Medical direction of 2-4 concurrent anesthesia procedures: When two to four concurrent anesthesia procedures are medically directed, report with modifier QK. Services submitted with modifier QK will be reimbursed at 50% of the applicable fee.” 

Medical direction of four CRNAs –> the anesthesiologist can bill 50% of Physician Allowed Amount and 50% of CRNA Allowed Amount.

With four operating rooms directed by one anesthesiologist, the 1st, 2nd, 3rd, and 4th operating rooms can each be billed at 50% of the anesthesia fee. Billing for four rooms simultaneously can increase the income for that solitary anesthesiologist over that time period. An anesthesiologist working alone, without CRNAs, can only attend to one patient, and can only bill services for a single patient. An analogy is a taxicab or Uber driver who can only bill for one ride at a time. The only way for a solo taxi driver or Uber driver to earn more money is to give more rides, and the only way for a solo anesthesiologist to earn more money is to do more cases for more hours of time.

The senior author of the University of Michigan study was Sachin Kheterpal, MD, MBA from the Department of Anesthesiology, yet the study was published in a surgical journal, JAMA Surgery, rather than an anesthesiology journal.Did anesthesiology journals reject the opportunity to publish the study? I don’t know. It’s pertinent that surgeons care greatly about the outcomes of surgeries they perform, and surgeons are less concerned with the economics of anesthesia staffing. Surgeons reading this study will no doubt conclude that an anesthesia group covering major noncardiac inpatient surgical cases with 1:3 or 1:4 anesthesiologist:CRNA staffing ratios are exposing their patients to an increased risk of morbidity and mortality.

Will this study change the anesthesiologist:CRNA staffing ratios in the future? My gut impression is that it will not. Anesthesiologists do not routinely read JAMA Surgery and may be quick to dismiss the findings. Surgeons may complain to their anesthesia colleagues that they do not want 1:3 or 1:4 anesthesiologist:CRNA staffing ratios for their major noncardiac inpatient surgical patients, but it’s unlikely they will have any power to enact change if the anesthesiologists don’t want to change. Why would anesthesiologists not move away from 1:3 or 1:4 anesthesiologist:CRNA staffing ratios? See the three reasons above: an inadequate supply of physician anesthesiologists; the quest to decrease anesthesia costs; and the goal of maximizing anesthesiologist income by directing 3 or 4 operating rooms at the same time.

I asked the anesthesia chairman of a large health-maintenance organization (HMO) how his group assigned anesthesia staffing, and his reply was that they used tiered staffing. A demanding case such as an open-heart surgery or a craniotomy was staffed by a solo physician anesthesiologist. In contrast, simple low-risk cases such as bunion repairs or carpal tunnel repairs on healthy patients were staffed by the maximal anesthesiologist:CRNA ratio of 1:4. The spectrum of remaining cases fell between these two extremes, and the anesthesiologist:CRNA ratio was assigned according to the difficulty and the risk of the anesthetic.

As a patient, how do you feel about all this? Would you be concerned if you were to be anesthetized by an anesthesia care team utilizing a 1:3 or 1:4 anesthesiologist:CRNA staffing ratio? In the University of Michigan study, if your surgery was a major noncardiac inpatient surgery during daytime hours, the data showed that your anesthesia team is putting you at increased risk for 30-day morbidity and mortality. The University of Michigan study only examined inpatient surgeries, so if you’re having outpatient ambulatory surgery, this study does not apply to your surgery. In 2014, outpatient surgery outnumbered inpatient surgery by 11,474,800 to 10,303,000. But if you or your family member are scheduled for major noncardiac inpatient surgery, it’s important to ask the question of what the anesthesiologist:CRNA staffing ratio will be while you or your family member are asleep, and how much of the time will your anesthesiologist be in the operating room.

If I was to be cared for by an anesthesiologist:CRNA ratio of 1:3 or 1:4 for a major noncardiac inpatient surgery during daytime hours, I would raise an objection before the anesthetic started, and I would direct my objection at both the attending anesthesiologist and the attending surgeon. Based on the data from the University of Michigan study, I would request an anesthesiologist:CRNA ratio of no higher than 1:2, or I would request a solo anesthesiologist to attend to me.

I’d suggest you do the same.

QUANTITATIVE NEUROMUSCULAR MONITORING –  NECESSITY OR TECHNOLOGY OVERDONE?

THE ANESTHESIA CONSULTANT
A QUANTITATIVE NEUROMUSCULAR MONITOR

How do anesthesiologists monitor the degree to which a patient’s muscles are pharmaceutically paralyzed during an anesthetic? A recent publication in our specialty’s most prestigious journal urges the use of a QUANTITATIVE neuromuscular monitoring machine to do this when general anesthetics include a paralytic drug. The article was not a prospective randomized study, but rather a retrospective (from 2016 to 2020) practice initiative from a solitary medical center. The goal of the authors (Weigel et al) was to measure the reversal of neuromuscular paralysis in all anesthetized patients at the end of their anesthetic, and to document that reversal in the patient’s chart.

Their measured goal was to document a train-of-four ratio of greater than or equal to 0.9 prior to extubation in each anesthetized patient. What is a train-of-four? A locomotive with four cars? Alas no. A train-of-four ratio is a monitor of the level of neuromuscular blockade. Four consecutive electronic stimuli are delivered along the path of a patient’s nerve. The twitch response of the muscle is measured in order to evaluate stimuli that are blocked, versus those that are delivered. Four consecutive muscle contractions of equal strength (a score = 1.0) occur if there is no neuromuscular blockade. If neuromuscular blockade is present, there will be a loss of twitch height of the final twitch compared to the first twitch, and the resulting ratio of the final twitch height/first twitch height (e.g. 4/5 = 0.8) will indicate the degree of blockade. The clinical concern is that a ratio of lower than 0.9 correlates with a weak patient who may not safely ventilate himself/herself.

The conclusion of the Weigel study boldly states, “Anesthesia providers are solely responsible for properly rescuing patients from the states of paralyses they initiate. This should occur for ALL PATIENTS as verified by QUANTITATIVE measurement and documentation of train-of-four ratios greater than or equal to 0.9.” (Capital letters added by me.) 

Should the American Society of Anesthesiologists (ASA) add QUANTITATIVE neuromuscular monitoring as a standard of care? 

Hmm. This would be a marked change because, to my observation, almost no anesthesia providers routinely use QUANTITATIVE neuromuscular monitoring at this time.

The authors’ goal of documenting a train-of-four ratio greater than or equal to 0.9 requires the purchase of QUANTITATIVE neuromuscular monitoring equipment in every anesthetizing location. The cost of each monitor was approximately $1,995, with the disposable costs of $20 to $25 per patient. An example QUANTITATIVE neuromuscular monitor is shown here:  

TwitchView QUANTITATIVE neuromuscular monitor

The article states, “The dangers of paralyzing a patient with neuromuscular blocking drugs are well recognized. Despite advances in anesthetic management, approximately half of all patients arriving to the postanesthesia care unit (PACU) suffer from residual blockade defined as a train-of-four ratio less than 0.9.” They cite a previous article from Anesthesia and Analgesia in 2018 which stated: “whenever a neuromuscular blocker is administered, neuromuscular function must be monitored by observing the evoked muscular response to peripheral nerve stimulation. Ideally, this should be done at the hand muscles (not the facial muscles) with a quantitative (objective) monitor. Objective monitoring (documentation of train-of-four ratio ≥0.90) is the only method of assuring that satisfactory recovery of neuromuscular function has taken place. (Bold emphasis added by me.) The panel also recommends that subjective evaluation of the responses to train-of-four stimulation (when using a peripheral nerve stimulator) or clinical tests of recovery from neuromuscular block (such as the 5-second head lift) should be abandoned in favor of objective monitoring.”

The American Society of Anesthesiologists (ASA) sets the standard of care for intraoperative monitoring. The ASA Standard of Anesthesia Monitoring currently does not mandate any form of neuromuscular monitoring. The ASA Standard of Anesthesia Monitoring is the gold standard for all operating room monitoring, is followed by all training programs, and is referred to in courts of law as the standard of care should an adverse anesthesia outcome occur. 

A 2010 survey of anesthesia providers documented that 19.3% of Europeans and 9.4% of Americans never use neuromuscular monitors. The majority of respondents from the US (64.1%) and Europe (52.2%) estimated the incidence of clinically significant postoperative residual neuromuscular weakness to be <1% (P<0.0001). Most respondents in this study reported that “neither conventional nerve stimulators nor quantitative train-of-four monitors should be part of minimum monitoring standards.”

I suggest three values in anesthetic care: Do the right thing, be safe, and Keep It Simple Stupid (the KISS principle). Rather than strapping a thumb monitor onto every one of my patients, I’m a disciple of qualitative neuromuscular monitoring—a less technologically complex form of monitoring. When I was serving my residency training in anesthesiology at Stanford in the 1980s, each resident was equipped with a MiniStim nerve stimulator, which is a qualitative neuromuscular monitor. 

MiniStim qualitative neuromuscular monitor

qualitative neuromuscular monitoring device is simple to use. When the two terminals are applied to the facial nerve lateral to the eye of a sleeping patient and the green button is pushed, the orbital muscles will twitch if unparalyzed, and they will not twitch if paralyzed. With experience one can easily discern whether the patient is paralyzed or not, and one can estimate the degree of paralysis. The MiniStim also has a tetanus feature. When the two terminals are applied to the facial nerve lateral to the eye of a sleeping patient and the red button is pushed, a sustained electrical energy is emitted between the two terminals. The orbital muscles will show a sustained contraction if unparalyzed, and will not contract at all if fully paralyzed. If partially paralyzed, the muscles will contract and then the contraction will fade away in seconds. With experience, one can estimate to what degree the patient is paralyzed. The qualitative neuromuscular monitor does not give you the exact data, i.e. a decimal number between 0.0 (totally paralyzed and 1.0 (no paralysis) that a QUANTITATIVE neuromuscular monitor does. 

I still carry a MiniStim, and have used one for the entire 38 years I’ve practiced anesthesia, and for the 30,000 patients I’ve anesthetized. I would not start a case without a neuromuscular qualitative monitor. I would not want to be a patient receiving a neuromuscular paralytic drug if the anesthesiologist did not utilize a neuromuscular monitoring device similar to the MiniStim. The MiniStim is no longer manufactured, but other similar qualitative neuromuscular monitors are easily purchased, e.g. as depicted below, for $251, with no additional disposable costs.

SunStim qualitative neuromuscular monitor

Why is the topic of reversing neuromuscular blockade seeing this kind of scrutiny in 2022? Residual neuromuscular paralysis is less a problem now than at any time since the paralyzing medications were discovered. Why? Because in 2015 the United States Food and Drug Administration (FDA) approved the new intravenous drug sugammadex, a reliable, specific, and safe agent for the reversal of neuromuscular paralysis. Sugammadex can eliminate neuromuscular paralysis rapidly. A rocuronium molecule, bound within sugammadex’s lipophilic core, is rendered unavailable to bind to the acetylcholine receptor at the neuromuscular junction, and paralysis is reversed in seconds. 

Prior to 2015, the only reversal agent for pharmaceutical paralysis with a non-depolarizing neuromuscular blocker such as rocuronium was the drug neostigmine. Neostigmine can cause the side effect of severe bradycardia (slowing of the heart rate), and had to be administered intravenously in combination with glycopyrrolate (Robinul) or atropine. If a surgery was concluding and the patient had residual neuromuscular paralysis, the anesthesia provider needed to administer the combination of neostigmine/Robinul well before the wakeup-time, because the peak effect of neostigmine occurs at 10 minutes after administration.  If the patient was markedly paralyzed, e.g. the qualitative neuromuscular monitor showed no significant twitch or tetanus activity, neostigmine could not adequately reverse the neuromuscular paralysis in a short time. Sometimes it took 20-30 minutes before a deep neuromuscular paralysis could be reversed with neostigmine. If an anesthesia provider erroneously chose to awaken a patient prior to the time their neuromuscular paralysis was reversed or worn off, the patient would be too weak to breathe normally. A medical complication of hypoventilation or of awake paralysis could occur. 

Because of sugammadex, the risk of untreated residual neuromuscular paralysis has never been lower. Unreversed neuromuscular paralysis at wake-up should be a never-event now that sugammadex exists. There is virtually no circumstance in which an attending anesthesia provider should have unreversed neuromuscular paralysis at the present time. Why, in 2022, should we advocate for a QUANTITATIVE neuromuscular monitor which is bulky, expensive, and can only be strapped onto the thumb? The thumb location is a disadvantage, because many anesthetics, for example laparoscopies, require the arms to be tucked at a patient’s sides during surgery, and a thumb monitor is not practical. The qualitative neuromuscular monitors work on any peripheral nerve: e.g. the ulnar nerve at the wrist, the facial nerve lateral to the eye, or the posterior tibial nerve in the ankle, and provide a more versatile monitor than the QUANTITATIVE neuromuscular thumb monitor.

Qualitative neuromuscular monitoring is useful, easy, versatile, and inexpensive. QUANTITATIVE neuromuscular monitoring has the appeal of a score—a number between 0 and 1.0—that can be added to the already burdensome printout of the Electronic Medical Record (EMR), and may seem satisfying to those addicted to the dubious wonders of the EMR, or to those who want to see QUANTITATIVE neuromuscular monitors reported in the medical literature. But the addition of QUANTITATIVE neuromuscular monitoring to the required ASA list of monitors at this time is premature.

Where is the science? Where is the prospective, randomized trial of QUANTITATIVE neuromuscular monitoring versus qualitative neuromuscular monitoring in the age of sugammadex? Does anyone really believe that qualitative neuromuscular monitoring will be inaccurate and lead to significant anesthetic complications in an era when sugammadex is available? 

Qualitative neuromuscular monitoring was always a solid idea. I made this point twelve years ago when I wrote, “During residency or during the years afterward, a MiniStim and a stethoscope are arguably the only tools of your own you need to carry into an operating room to conduct a 21st-century general anesthetic.”

Until prospective scientific evidence demonstrates that QUANTITATIVE neuromuscular monitoring improves outcomes, mandating the extra technology of QUANTITATIVE neuromuscular monitoring as a required standard is not the correct path for the ASA to take in 2022 or at any time in the future.

THE DIFFERENCE BETWEEN A PHYSICIAN ANESTHESIOLOGIST AND A NURSE ANESTHETIST

THE ANESTHESIA CONSULTANT

What’s the difference between a physician anesthesiologist and a nurse anesthetist? After the first 3 – 4 years in the workforce, either one can master the manual skills of anesthesia. That is, either one can display excellence in intubating the trachea, performing a spinal or an epidural anesthetic, performing a nerve block, inserting an arterial line, or inserting a central venous pressure catheter. There is no fork in the career path that makes a busy Certified Registered Nurse Anesthetist (CRNA) automatically inferior to a medical doctor anesthesiologist in hands-on skills. So what really is the difference between a physician anesthesiologist and a nurse anesthetist? The answer: internal medicine.

All physician anesthesiologists graduate from medical school, where they rotate through clerkships in surgery, pediatrics, obstetrics-gynecology, internal medicine, emergency medicine and psychiatry, as well as electives in surgical or medicine subspecialties of their choice.

By contrast, CRNAs are registered nurses experienced in intensive care or emergency room nursing, who then enter a 2 – 3 year program of learning the skills to anesthetize patientsCRNAs can now administer anesthesia independent of any physician anesthesiologist supervision in the majority of the United States

The difference between a physician anesthesiologist and a nurse anesthetist is that the former has a depth of knowledge of 1) the physiology of the human body, 2) the pathophysiology of diseases, 3) the breadth of pharmacology, and 4) the ability to make diagnoses and prescribe treatment. In short, the physician anesthesiologist has extensive training in the internal medicine essentials of 1), 2), 3), and 4) above.

Nurse anesthetists are valuable and integral cogs in American healthcare. It’s not my intention to demean or minimize the role of CRNAs. My goal is to point out the most specific difference between a physician anesthesiologist and a nurse anesthetist.

At Stanford our department is named the Department of Anesthesiology, Perioperative and Pain Medicine. What is Perioperative Medicine? Perioperative Medicine is all the medical care before, during, and after surgery. Is Perioperative Medicine a subspecialty of internal medicine? In a way, it is. Following an internal medicine residency, graduates may subspecialize in cardiology, oncology, pulmonary medicine, kidney medicine, infectious disease, critical care, or . . . perioperative medicine. When I finished my Stanford internal medicine residency, the top four choices among my colleagues for the next step were: #1 a cardiology fellowship, #2 general internal medicine private practice, #3 an anesthesia residency, or #4 an oncology fellowship.

Stanford University now offers a combined internal medicine/anesthesiology residency, with the goal of training leaders in anesthesiology. The PGY1 year is spent entirely on medicine rotations.  The PGY2 year consists of all anesthesia rotations.  During PGY3-5 years, the resident alternates between 3 months of medicine rotations and 3 months of anesthesia rotations.

The outgoing Chairman of Anesthesiology, Perioperative and Pain Medicine at Stanford is Ronald Pearl MD PhD, an outstanding clinician and scientist who led our department for twenty-two years. In addition to board-certification in internal medicine and anesthesiology, Dr. Pearl is also board certified in critical care medicine. Dr. Pearl is one of the smartest clinicians I’ve ever met. His extensive internal medicine knowledge raises him above other anesthesia providers. 

Currently, anesthesiology residency programs are three years in duration, beginning after a resident has completed at least one year of internship. During those three years of anesthesia residency (PGY2 – PGY4) the resident rotates through

  • two one-month rotations in: obstetric anesthesiology, pediatric anesthesiology, neuro anesthesiology, and cardiothoracic anesthesiology
  • a minimum of one month in the adult intensive care unit during each of the three years 
  • three months of pain medicine, including one month in acute perioperative pain, one month in chronic pain, and one month of regional analgesia/peripheral nerve blocks
  • one-half month in a preoperative evaluation clinic 
  • one-half month in a post anesthesia care unit, and one-half month in out-of-OR locations.  

These rotations of an anesthesia resident develop the young doctor into a clinician comfortable in preoperative assessment and management, in the intraoperative administration of anesthesia, and in the postoperative evaluation and treatment of patients. 

Currently, internal medicine residency programs are three years in duration, including a one-year internship in internal medicine. During those three years (PGY1 -PGY3) a resident rotates through: 

  • a minimum of 4 months of critical care (medical ICU or cardiac care unit) rotations
  • a minimum of 1/3 of Internal Medicine training occurs in an ambulatory setting
  • a minimum of 1/3 of Internal Medicine training occurs in an inpatient setting
  • a longitudinal continuity clinic of 130 one-half-day sessions over the course of training, including one clinic per month. The continuity clinic includes evaluation of performance data for resident’s panel of patients.
  • exposure to each of the internal medicine subspecialties and to neurology
  • an assignment in geriatric medicine
  • an emergency medicine experience of four weeks
  • electives available in psychiatry, allergy/immunology, dermatology, medical ophthalmology, office gynecology, otorhinolaryngology, non-operative orthopedics, palliative medicine, sleep medicine, and rehabilitation medicine

These rotations of an internal medicine resident develop the young doctor into a broadly trained clinician experienced in multiple areas.

I’m not advocating that anesthesia departments be folded under the umbrella of their institution’s department of internal medicine. Instead, what I am recognizing is that the field of anesthesiology is more than putting in breathing tubes, arterial catheters, IV lines, or nerve block needles in a variety of different surgical settings. The field of anesthesiology is understanding and managing medical problems before, during, and after surgery, i.e., Perioperative Medicine. Describing our specialty with the word “Anesthesia” is an oversimplification of what we do. If our specialty was newly named today, it would be called Perioperative Medicine, period.

What about pediatric perioperative medicine? Doesn’t pediatric perioperative medicine involve the knowledge base of pediatricians, instead of the knowledge base of internal medicine? Yes. Deep knowledge of pediatric medicine instead of internal medicine (on adult patients) applies to pediatric perioperative medicine. No doubt a pediatrician who then completes an anesthesia residency will likely be an outstanding pediatric perioperative doctor, but only 5.4 % of anesthesia care in the United States is on pediatric patients less than 15 years old. The majority of the knowledge base for anesthesia care pertains to adult patients, i.e. the knowledge base for internal medicine physicians.

Several examples will illustrate why internal medicine forms the backbone of perioperative anesthesia practice. Before surgery, a patient who presents with insulin dependent diabetes, hypertension, hyperlipidemia, and obstructive sleep apnea is an example of the kind of patient an internal medicine doctor sees regularly in his or her outpatient clinic. During surgery, a patient who develops atrial fibrillation or marked hypertension is an example of the kind of events an internal medicine doctor sees in an intensive care unit. After surgery, a patient who presents with chest pain or shortness of breath is an example of the kind of patient an internal medicine doctor sees in the emergency room or in the intensive care unit. Wait . . . you can argue that a CRNA has previous experience working as a registered nurse in an ICU or an emergency room before beginning nurse anesthetist training. But a registered nurse in an ICU or an emergency room does not independently diagnose and treat medical conditions. A registered nurse in an ICU or an emergency room follows written orders from a medical doctor. There is a world of difference between a medical doctor commanding diagnosis and treatment in an ICU/emergency room versus a registered nurse who follows orders.

Should all anesthesia residency training follow the Stanford optional model of combining internal medicine and anesthesia residencies into one program? No. Prolonging the training of every physician anesthesiologist in the United States makes little sense, but those who desire to be leaders will consider this double-residency option. 

Recent years brought an attempt to rename the territory of anesthesiologists as the “Perioperative Surgical Home.”  The Perioperative Surgical Home is defined as “a patient-centered, team-based, and coordinated perioperative care setup, composed of the head anesthesiologist-perioperativist in tandem with dedicated nurse practitioners and other PSH team doctors.” This is a move in a positive direction, with the intent of better patient care coordinated by an anesthesiologist-led team. There is an economic barrier to the Perioperative Surgical Home, in that the PSH may appear to be a coup attempt for anesthesia departments to take over jurisdictions from preoperative and postoperative internal medicine doctors. Any adoption of the PSH will likely be gradual, as the battle for patients plays out in each medical center.

Instead, a first step is that anesthesia departments redefine themselves as Departments of Perioperative Medicine, and that the academic training for these departments involve increasing time spent expanding the internal medicine knowledge base of residents in medical intensive care units, cardiac intensive care units, medicine wards, and medicine clinics. Performing month after month of repetitive intraoperative anesthesia care has a decreasing return on expanding a resident’s fund of knowledge, and can serve to make the role of a physician anesthesiologists and the role of a nurse anesthetist close to being the same.

It’s important that physician anesthesiologists create perceivable differences between themselves and CRNAs. The role of Perioperative Medical Doctors is a more broad and more specific identity when compared to what nurse anesthetists do. Let’s make our young physician anesthesiologist trainees into Perioperative Medicine Specialists, instead of confusing them with other anesthesia professionals who can also administer propofol, sevoflurane, and rocuronium.

THE ANESTHESIA CONSULTANT
The first public demonstration of anesthesia, at the Ether Dome in Massachusetts General Hospital

Important advances in the history of anesthesia changed medicine forever. Humans have inhabited the Earth for 200,000 years, yet the discovery of surgical anesthesia was a relatively recent development in the mid-1800s. For thousands of years most surgical procedures were accompanied by severe pain, and the only strategies available to decrease pain were to give patients alcohol or opium until they were stuporous. How did our specialty advance from prescribing patients two shots of whiskey to administering safe modern anesthesia? In chronologic order, my choices for the most important doctors in the history of anesthesia are:

1842. Dr. Crawford Long, Georgia, USA. THE CO-DISCOVERER OF ETHER AS A GENERAL ANESTHETIC.  Dr. Long was an American surgeon recognized for introducing the use of inhaled ether as a general anesthetic. Dr. Long administered ether for the first time on March 30, 1842, to remove a tumor from the neck of patient James Venable. Dr. Long dripped ether on a towel through which Mr. Venable inhaled. Dr. Long performed multiple surgeries using this technique, but did not publish his findings until seven years later in 1849 in The Southern Medical and Surgical Journal. As a result, there is a dispute whether Dr. Crawford Long or Dr. William Morton (below) discovered ether anesthesia first. 

1846. Dr. William Morton, Boston, USA. THE FIRST PUBLIC DEMONSTRATION OF ETHER AS A GENERAL ANESTHETIC.  Dr. Morton performed the first public demonstration of general anesthesia at Harvard’s Massachusetts General Hospital on October 16, 1846. Morton, a local dentist, utilized inhaled ether to anesthetize patient Gilbert Abbott for removal of a tumor on the patient’s neck. According to surgeon John Collins Warren’s account of the operation, “(the patient) said that he had felt as if his neck had been scratched; but subsequently, when inquired of by me, his statement was, that he did not experience pain at the time, although aware that the operation was proceeding. Morton was unaware of Dr. Crawford Long’s prior work which began four years earlier in 1842. Morton published his accomplishment in the December 1846 issue of Medical Examiner. Comment: Both Dr. Long and Morton deserve recognition for the discovery and eventual application of ether as a general anesthetic drug. The invention of ether changed medical care forever, making painless surgery a reality.

1853.  Dr. Alexander Wood, Scotland. THE DISCOVERY OF THE HYPODERMIC NEEDLE, THE SYRINGE, AND THE INJECTION OF MORPHINE. Dr. Wood invented a hollow needle that fit on the end of a piston-style syringe, and used the syringe and needle combination to successfully treat pain by injections of morphine.  Comment: Most anesthetic drugs today are injected intravenously. Such injections would be impossible without the invention of the syringe.

1885. Dr. William Halsted, Baltimore, USA. THE DISCOVERY OF INJECTABLE COCAINE AND LOCAL ANESTHESIA.  Cocaine was the first local anesthetic discovered. Dr. Halsted of Johns Hopkins University first injected 4% cocaine into a patient’s forearm and concluded that cocaine blocked sensation. The patient’s arm was numb below but not above the point of injection. Halstead became addicted to cocaine, and later to morphine.  Comment: The discovery of local anesthesia gave doctors the power to block pain in specific locations. The improved local anesthetics procaine (Novocain) and lidocaine were later discovered in 1905 and 1948, respectively.

1899. Dr. August Karl Gustav Bier, Germany. THE FIRST TO PERFORM SPINAL ANESTHESIA, AND ALSO THE INVENTOR OF THE BIER BLOCK (AN INTRAVENOUS REGIONAL ANESTHESIA TECHNIQUE FOR HAND OR FOOT SURGERY).  Dr. Bier was a German surgeon before the concept of an anesthesia specialist was invented. He performed the first surgery under spinal anesthesia in 1899. Dr. Bier injected cocaine through a spinal needle, which paralyzed the lower half of his patient. Dr. Bier was able to perform painless ankle surgery. The patient was fully conscious during the operation. Comment: Dr. Bier was the father of regional anesthesia, an important tool in the repertoire of a modern anesthesiologist.

Dr. Nikolai Korotkov

1905. Dr. Nikolai Korotkov, Russia. THE DISCOVERY OF THE MEASUREMENT OF BLOOD PRESSURE BY BLOOD PRESSURE CUFF. Dr. Korotkov described the sounds produced during auscultation with a stethoscope over a distal portion of an artery as a blood pressure cuff was deflated. These Korotkoff sounds resulted in an accurate determination of systolic and diastolic blood pressure. Comment: Anesthesiologists monitor patients repeatedly during every surgery. A patient’s vital signs are the heart rate, respiratory rate, blood pressure, oxygen saturation, and temperature. It would be impossible to administer safe anesthesia without blood pressure measurement. Low blood pressures may be evidence of anesthetic overdose, excessive bleeding, or heart dysfunction. High blood pressures may be evidence of inadequate anesthetic depth or uncontrolled hypertension.

The cuffed endotracheal tube
Dr. Aurthur Guedel

1932. Dr. Arthur Guedel, Wisconsin, USA. DEVELOPMENT OF THE CUFFED ENDOTRACHEAL BREATHING TUBE. Dr. Guedel added an inflatable cuff to the distal end of a breathing tube to be inserted into a patient’s trachea. This advance allowed the use of positive-pressure ventilation into a patient’s lungs. Comment: Surgery within the abdomen and chest would be impossible without controlling the airway and breathing with a tube in the trachea. Advanced cardiac life support (ACLS) of Airway-Breathing-Circulation depends on the insertion of a cuffed endotracheal tube.

1927. Dr. Ralph Waters, University of Wisconsin, USA. THE FIRST ANESTHESIA RESIDENCY PROGRAM. Before Dr. Waters, a variety of individuals administered anesthesia. He developed the first department of anesthesia at a medical school, and established the first resident training program in anesthesia. He is considered the “father of academic anesthesia.” Dr. Waters also introduced the anesthetic gas cyclopropane into clinical use, the carbon dioxide absorption method on the anesthesia machine, and endobronchial anesthesia for thoracic surgery. Comment: Every university anesthesia residency program owes a debt to the legacy of Ralph Waters. 

Dr. John Lundy

1934. Dr. John Lundy, Mayo Clinic, Minnesota, USA. THE INTRODUCTION OF INTRAVENOUS THIOPENTAL AND INJECTABLE BARBITURATES.  Dr. Lundy of the Mayo Clinic in Rochester, Minnesota introduced the intravenous anesthetic sodium thiopental into medical practice. In 1934, Dr. Ernest Volwiler and Dr. Donnalee Tabern synthesized Pentothal, the first intravenous general anesthetic. Pentothal was first used in humans on 8 March 1934 by Dr. Ralph Waters. Three months later, Dr. John Lundy started clinical trials of thiopental at the Mayo Clinic at the request of Abbott Laboratories. Injecting Pentothal provided a more pleasant induction of anesthesia than inhaling pungent ether. Comment: This was a huge breakthrough. Almost every modern anesthetic begins with the intravenous injection of an anesthetic drug. (Propofol has now replaced Pentothal.)

1941, Dr. Robert Miller, Texas, USA. INVENTION OF THE MILLER INTUBATING LARYNGOSCOPE BLADE. The Miller straight laryngoscope blade was used to elevate the epiglottis and enabled anesthesiologists to directly view the vocal cords and the laryngeal opening in an anesthetized patient, so they could directly place an endotracheal breathing tube into the trachea. Comment: The Miller straight laryngoscope blade is the second most common blade used for direct laryngoscopy today, and my personal favorite.

Dr. Harold Griffith

1942. Dr. Harold Griffith, Montreal, Canada. THE DISCOVERY OF CURARE, THE FIRST INJECTABLE MUSCLE RELAXANT.  Dr. Griffith injected the paralyzing drug curare to 25 patients during cyclopropane general anesthesia to induce muscular relaxation. Although the existence of curare was known for many years—it was used on poison arrows by South American Indians—it was not used in surgery to deliberately cause muscle relaxation until this time. Comment: Paralyzing drugs are necessary to enable the easy insertion of endotracheal tubes into anesthetized patients, and paralysis is also essential for many abdominal and chest surgeries.

1943, Dr. Robert Macintosh, England.  INVENTION OF THE MACINTOSH INTUBATING LARYNGOSCOPE BLADE. The Macintosh curved laryngoscope blade enabled anesthesiologists to indirectly elevate the epiglottis and view the vocal cords and the laryngeal opening in an anesthetized patient, so they could directly place an endotracheal breathing tube into the trachea. Comment: The Macintosh curved laryngoscope blade is the most common blade used for direct laryngoscopy today.

ventilating the lungs by bag-ventilation via a tracheostomy

1953. Dr. Bjorn Ibsen, Denmark. THE DEVELOPMENT OF THE FIRST INTENSIVE CARE UNIT (ICU).  The origin of the ICU followed the Copenhagen polio epidemic of 1952, which caused respiratory failure in hundreds of patients. Hundreds of patients required ventilation for weeks. Dr. Ibsen organized over a thousand medical students who positive-pressure-ventilated the lungs of these patients by bag-ventilation via tracheostomies. This gathering uniting of physicians and medical students to manage sick patients led to Ibsen being considered the “father of intensive care.” Comment: In the ICU, the Airway-Breathing-Circulation management perfected in the operating room was extended to critically ill patients who were not undergoing surgery.

1956. Dr. Charles Suckling. THE DISCOVERY OF HALOTHANE, THE FIRST MODERN INHALED ANESTHETIC. British chemist Charles Suckling synthesized the inhaled anesthetic halothane. Halothane had significant advantages over ether or cyclopropane. Halothane had a more pleasant odor, a higher potency, faster onset, and was nonflammable. Halothane gradually replaced older anesthetic vapors and achieved worldwide acceptance. Comment: Halothane was the forerunner of our modern inhaled anesthetics isoflurane, desflurane, and sevoflurane. These drugs have faster onset and offset times, cause less nausea, and are not explosive like ether was. The discovery of halothane changed inhalation anesthesia forever.

Dr. John Severinghaus and the first blood gas analyzer

1957. Dr. John Severinghaus, UCSF, California, USA. THE FIRST MEASUREMENT OF ACID/BASE CHEMISTRY OF HUMAN BLOOD.  Dr. Severinghaus developed the first blood gas analyzer, now on display in the Smithsonian Museum, which measured the pH, pCO2, and pO2 in a sample of arterial blood. https://www.mlo-online.com/continuing-education/article/13008466/blood-gas-testing-a-brief-history-and-new-regulatory-developments  He also developed the initial methods for measuring end-tidal gas concentrations in anesthetized patients in the mid-1970s, and he worked with Dr. Eger (below) on the discovery of minimum alveolar concentration of inhaled anesthetics. He died in 2021 at the age of 99 years. Comment: Measuring blood gases in an acutely ill patient is a cornerstone of all ER and ICU medicine. Measuring blood gases is also routine in cardiac, neurosurgical, and trauma anesthesia, and the measurement of end-tidal gas concentration is a standard in general anesthetics today.

1960s. Dr. Ted Eger, UCSF, California, USA. DISCOVERY OF THE MINIMUM ALVEOLAR CONCENTRATION OF POTENT INHALED ANESTHETICS. Dr. Eger defined the science of inhaled anesthesia uptake and concentration when he characterized the Minimum Alveolar Concentration (MAC) of every gaseous anesthesia drug. Per Dr. Eger’s New York Times obituary when he died at the age of 86 in 2017, he was “a leader in the development of a now universally used technique to determine the proper dose of anesthetic gas administered in operating rooms.” Comment: Almost every general anesthetic today includes some form of an inhaled anesthetic such as sevoflurane, desflurane, or nitrous oxide. Dr. Eger’s work defined the principles of how much gas to administer to each patient.

A pulse oximeter probe
Dr. William New

1983. Dr. William New, Stanford University, California, USA. THE DEVELOPMENT OF PULSE OXIMETRY MONITORING. The Nellcor pulse oximeter, co-developed by Stanford anesthesiologist Dr. William New, was the first commercially available device to measure the oxygen saturation in a patient’s bloodstream. The Nellcor pulse oximeter had the unique feature of lowering the audible pitch of the pulse tone as the oxygen saturation dropped, giving anesthesiologists an audible early warning that their patient’s heart and brain were in danger of low oxygen levels. Comment: The Nellcor changed patient monitoring forever. Oxygen saturation is now monitored before, during, and after every surgery. Prior to Nellcor monitoring, the first sign of low oxygen levels was often a cardiac arrest. Following the invention of the Nellcor, oxygen saturation became the fifth vital sign, along with pulse rate, respiratory rate, blood pressure, and temperature.

1987. Dr. Archie Brain, England. DEVELOPMENT OF THE FIRST COMMERCIAL LARYNGEAL MASK AIRWAY. The Laryngeal Mask Airway (LMA) replaced the endotracheal tube as the airway device for many general anesthetics. The LMA can be inserted blindly into a patient’s mouth, does not require the patient to be paralyzed for insertion, is an easy method for securing the airway, and does not require a laryngoscope. The LMA was introduced to the United States market in 1992. Comment: The LMA revolutionized the general anesthetic technique for most extremity surgeries, some head and neck surgeries, and is used as a rescue technique in the American Society of Anesthesiologists Difficult Airway Algorithm (see below).

1990s. Dr. Jonathan Benumof, UCSD, San Diego, California, USA.  DEVELOPMENT OF THE DIFFICULT AIRWAY ALGORITHM. Dr. Benumof was the main originator of the American Society of Anesthesiologists Difficulty Airway Algorithm, first published in 1996. The Difficult Airway Algorithm describes pathways to safe airway management, and its application has saved countless lives. Comment: The Difficult Airway Algorithm is the standard of care for managing patients who are difficult to intubate and/or oxygenate. All anesthesiology providers commit the algorithm to memory, because when airway disasters occur there is simply no time for them to Google the correct order of rescue procedures.

The GlideScopy
Dr. John Pacey

2001. Dr. John Pacey, vascular and general surgeon, University of British Columbia, Canada. INVENTION OF THE GLIDESCOPE, THE WORLD’S FIRST VIDEOLARYNGOSCOPE. Dr. Pacey introduced the GlideScope (Verathon) as the first commercially available video laryngoscope in 2001. The GlideScope combined two new technologies: the video laryngoscope and the hyper-angulated laryngoscope blade, and enabling doctors and CRNAs to “see around the corner” of the airway to place endotracheal tubes into the trachea of  patients with difficult airways. Comment: Note that Dr. Pacey and several other doctors on this Top 20 List invented improvements in airway management. Failed airway management remains the most dreaded complication in anesthesia practice, as it can lead to anoxic brain damage. We are thankful to Drs. Arthur Guedel, Ralph Waters, Robert Miller, Robert Macintosh, Archie Brain, Jon Benumof, and John Pacey, whose inventions made intubation of the difficult airway . . . less difficult. 

These are the top 20 doctors who made major advances in the history of anesthesia as I see them. Who will be the next successful inventor to advance our specialty? At Stanford University our department is titled the Department of Anesthesiology, Perioperative and Pain Medicine. A key question for the future of Anesthesiology is “How do anesthetics work on the brain?” A key question for the future of Pain Medicine is “How can we more effectively block pain?” In 2016 an estimated 20.4% of the adults in the United States had chronic pain, and the relief of pain remains a key unsolved problem. Anesthesiologists or scientists who develop answers to these questions will likely join The Top Doctors in the History of Anesthesia list.

AUTHOR’S NOTE: The ultimate chronicle of anesthesia history is The Wondrous Story of Anesthesia, edited by Dr. Ted Eger, Dr. Laurence Saidman, and Dr. Rod Westhorpe. It’s available on Amazon and deserves to be on the bookshelf of every medical library in the world.

WHEN INTERNS AND RESIDENTS UNIONIZE

THE ANESTHESIA CONSULTANT

On May 2, 2022, residents and fellows (medical doctors in their first years of educational work after medical school) at Stanford University Health Care voted to unionize. In an email to medical staff, the Graduate Medical Education administration wrote: “Stanford Health Care (SHC) residents and fellows voted in favor of having The Committee of Interns and Residents (CIR), a local of Service Employees International Union (SEIU), serve as their collective bargaining representative. The votes cast in the election represent the sentiment of 1,049 residents and fellows who participated, out of the 1,478 employed by SHC. Ultimately, 835 voted ‘yes’ to unionization; 214 voted ‘no.’ . . . While we believe that the best relationship with our employees is a direct one without a union, we respect the results. . . . When the results are certified in the coming days, the first stages of the collective bargaining process will begin. . . . We will negotiate with the union in good faith to reach an agreement that reflects your priorities, while maintaining the best parts about training at Stanford.”

Stanford residents and fellows are not alone in choosing to unionize. A total of 1450 residents and fellows at UCSF (University of California San Francisco) recently voted to join the same Committee of Interns and Residents (CIR) union. The UCSF residents stated, “By joining CIR, UCSF residents will be able to negotiate their contracts for the first time, including bargaining for better salaries, benefits, time off, and other provisions that will improve resident life and well-being.” 

A total of over 20,000 residents and fellows at hospitals around the U.S. have voted to join this CIR union. What will this development mean to healthcare in the United States? I respect residents and fellows at the highest level. I spent five years as a medical resident, and I can empathize with the demands of their workload. From my current perspective as an attending physician at an academic medical center, how will this unionizing of housestaff (MDs who are residents and fellows) play out? 

First off, why form a union? The main reasons are a lack of bargaining power regarding:

  1. Burnout and staffing. Housestaff work up to 80 hours per week, a number that is twice the 40-hour workweek considered standard in the United States, and they do this for a duration of 3 to 7 years, depending on their specialty.  The rate of burnout is known to be high in medical doctors, and despite nods to wellness programs at most university hospitals, improvements have been slow in coming. An online survey of doctors finds an overall physician burnout rate of 42%, and the highest percentage of burnout occurred in these six specialties: urology: 54%, neurology: 50%, nephrology: 49%, diabetes and endocrinology: 46%, family medicine: 46%, and radiology: 46%.
  2. COVID. The long hours and risks of acquiring COVID while working with sick COVID patients from 2020 -2022 made many residents and fellows feel vulnerable and angry. While hospital administrators and many faculty returned to the safe havens of their homes each night, interns and residents staffed intensive care units, wards, and emergency rooms, caring for patients with this terrifying new contagious disease. When University of Massachusetts interns and residents joined the CIR union, they stated, “When the pandemic struck, securing better conditions became even more urgent, as the inequities in our healthcare system were laid bare — and in light of the rapid changes that left residents scrambling to keep up within traumatizing and sometimes dangerous practice conditions.”
  3. Higher pay. Residents and fellows are paid a salary. They do not earn an hourly wage. When their salary is divided by 80 hours of work per week, 50 weeks per year, most residents and fellows are making less than minimum wage. When University of Massachusetts interns and residents joined the CIR union, they stated, “UMass Memorial residents are willing to work 80 hours per week because we know exceptional care is critical to community well-being, but we are significantly underpaid for doing so.” 
  4. Better benefits. Residents and fellows will desire more vacation time, top-notch health insurance benefits, and perhaps even retirement contributions.

If residents and fellows don’t receive what they seek during negotiations with the administration, what consequence can residents and fellows turn to? Will they go on strike? In May 2019, interns and residents at UCSF staged a 15-minute “Unity Break” strike as a show of solidarity and power. The Committee of Interns and Residents, which represented 1,100 of UCSF’s resident and fellow population at that time, said that management had not properly recognized the contributions of their resident and intern members and offered a package that left them underpaid and underrepresented. “UCSF has failed to meet some of the very basic demands that we have been fighting for at the table,” said Kim Carter, director of the union. 

Can doctors strike? Is it ethically OK for doctors to strike? I think the answer is no. To leave patients without healthcare while doctors strike for better hours, wages, and benefits is a violation of the ethics of our healing profession. I don’t believe young doctors should be abused or squeezed into unacceptable hours, low wages, and/or poor benefits, but doctors staging a labor walkout would be a mistake. And if a union will never strike, will it ever have any real negotiating power? The CRONA (Committee for the Recognition of Nursing Achievement) nursing union at Stanford staged a strike beginning April 25, 2022, just days ago. Negotiations were successful after only one week of the strike, with the nurses gaining a tentative agreement for significant base wage increases of 5% on April 1, 2022, 2% on December 1, 2022, 5% on April 1 2023, and 5% on April 2024, in addition to other improvements in benefits, staffing, and scheduling. 

I have firsthand experience with strikes. I was a laborer during three United Steelworkers of America strikes in Northern Minnesota during summer employment in taconite mines while I was in college and medical school. Blue-collar strikes are not pretty. The picket lines were brutal, and no one dared cross them. Both sides lost money as the strikes wore on, and interpersonal conflicts simmered for a long time afterward. 

The idea of residents and fellows joining a union is not a new one. In 2001 The Los Angeles Times reported a story on this topic. The article stated, “Striking will disrupt the educational progression of classes, clinical practice and testing. A student wants to come in and have some certainty that his or her three-year residency will take three years. How would they feel if suddenly they were told they wouldn’t finish on time and, whether a strike is a good idea or a bad one, that they’re not going to be able to take a board exam?” One of the doctors who joined the union at that time stated, “Change won’t come overnight, but I think it will happen. We have to stop that cowboy attitude: ‘It’s always been this way, we’re tough, we don’t complain.’ Many residents want to complain, but they’re in an environment where if they do, they’re punished. Residents have to fight for all these things and, without a union, they don’t have any legs to stand on.”  

The ”cowboy attitude” refers an old-school medical education argument that sounds like this: “There’s no other way to educate doctors. It takes at least 80-100 hours per week. Even if you stay in-house every other night you miss half the good cases. When I was a resident, back in the (fill in the blank . . . 1950s, 1960s, 1970s, or 1980s), we slept in the hospital every other night and worked 120 hours per week. Now residents are complaining that 80 hours per week is too much.”

When I was an internal medicine resident in the 1980s, we stayed in the hospital on-call every third night and worked approximately 100 hours per week. My salary during my first year of residency was $16,000. On an hourly basis, this equated to $3.33 per hour. Adjusted for inflation, my 1980 salary would be $55,826, or $11.63 per hour, less than the current minimum wage. 

If medical centers shorten the workweek of interns and residents to 40 hours per week from the current limit of 80 hours per week, the medical center may need to hire twice as many interns and residents or other physician surrogates to do the workload. And if the union negotiates a 10-20% increase in annual salary, the cost for interns and resident would increase further. Where will all this money come from? Most of the salaries of residents and fellows are paid for by billions of dollars of federal tax money, as medical education is subsidized by the United States government. The publication Congressional Research Sources states, “Federal support for medical residency training (a.k.a., graduate medical education [GME]) is the largest source of federal support for the health care workforce. Although the health workforce includes a number of professions, the size of the federal investment in GME—estimated at $16 billion in 2015—makes it a policy lever often considered to alter the health care workforce and impact health care access.” 

Labor unions in the United States are organizations that represent workers in many industries. Labor unions grew afterCongress passed the National Labor Relations Act (NLRA) in 1935 to protect the rights of both employees and employers, to encourage collective bargaining, and to eliminate certain private sector labor and management practices which could harm the welfare of workers, businesses and the economy.

The Ailing Labor Rights of Medical Residents, by Sarah Geiger, published in 2006, describes the legal history of medical resident labor law and the attempts to legalize unionization among medical residents. I quote the following excerpts directly from Geiger’s paper: 

“From 1947 to 1974, hospital staff members did not have the right to unionize. . . . Congress then amended the NLRA in 1974 to include non-profit hospitals. The Committee on Labor and Public Welfare report on the amendments stated that it could find no acceptable reason why 1,427,012 employees of these non-profit, non-public hospitals, representing 56% of all hospital employees, should continue to be excluded from the coverage and protections of the Act. . . . One source of confusion involved the dubious supervisory status of professional health care providers. . . . health care professionals exercised supervisory roles and were thus excluded from the right to unionize. . . .

In Cedars-Sinai Medical Center, the NLRB held that the residents, interns, and clinical fellows of Cedars-Sinai were not ‘employees’ within the meaning of the NLRA. Thus, they had no right to unionize. . . . The Board thus concluded that interns, residents, and clinical fellows were primarily students, noting the relationship between residents and Cedars-Sinai was primarily educational, and not an employment relationship. . . .  The decision remarked that interns ‘participate in these programs not for the purpose of earning a living; instead they are there to pursue the graduate medical education that is a requirement for the practice of medicine. This statement implies that residents do not actually ‘practice medicine,’ but merely are training to do so. . . . 

“In response to staunch legal criticism, the Board reversed Cedars- Sinai.  Boston Medical, an oft-quoted case, involved a unit of housestaff at the Boston Medical Center (BMC) that attempted to unionize. . . .  The Board overruled its precedent in Cedars-Sinai and held that medical interns and residents were both students and employees and thus were entitled to unionize. . . . The NLRB recognition of housestaff’s plight has done little to encourage unionization among medical interns and residents. . . . The residents’ dual roles, however, present extra-legal barriers to unionization which are not present in other industries. Residents spend an inordinate number of hours in the hospital and often are directly serving patients for twenty-four hours at a time. . . .  the fears of Congress (and earlier fears of the American Medical Association) that unionization may compromise the doctor-patient relationship or the quality of health care residents adds another layer of complication. . . .   

“The Association of American Medical Colleges (AAMC), the representative body of all accredited medical schools in the United States and Canada, as well as over 400 teaching hospitals, vehemently opposed all resident unionization efforts. . . . Offering more labor rights to medical residents would cost academic hospitals inordinate amounts of money. The cost of replacing one surgical resident with a “physician extender,” or other physician, is $210,000 to $315,000 a year. . . . the federal government is by no means an objective observer in the matter of medical residency funding and regulations. Currently, the federal government is the main financier of graduate medical education, ‘contributing $6.8 billion through Medicare, plus additional sums through the Departments of Defense and Veteran Affairs.’ The federal government is constantly looking to reduce the cost of medical care. Offering residents more control over their working conditions would likely lead them to demand more money, money that would have to come from the federal government or from private university hospitals. Thus, the government and academic hospitals are appropriate bedfellows in opposing resident labor rights. 

“The Boston Medical decision made it clear that little legal basis exists to deny medical residents unionization rights or any NLRA specified rights for that matter. Thus, unless Congress amends the NLRA, no legal barriers exist to housestaff unionization.  Many other internal barriers, however, hinder medical residents from acquiring labor rights. Unionization takes more effort than residents have time for and many fear unions will compromise their goals as physicians. A national survey of residents found that residents’ willingness to get involved in forming a union or serving as a member of union management was inversely proportional to the difficulty and amount of time their specialty required them to be in the hospital. Residents are accountable to their superiors for their future careers and would rather endure a few years of grueling working conditions than do anything which might compromise their careers. . . . Hospitals should give residents a real opportunity to unionize. . . . An informed, inclusive dialogue will serve to clarify legal and extra-legal barriers to accomplishing these congressional goals as well as to alleviate medical residents’ labor burdens.”

As described above, a crucial issue which complicates union negotiations for medical residents and fellows is that their jobs are part work and part education. Each intern or resident is a medical worker, a student of the specialty he or she is training in, and a teacher to the interns and residents who are junior to them in the hierarchy. Residents and fellows are learning as they are paid to work. Their learning is both valuable and necessary for progression to their eventual career. The U.S. News and World Report’s listing of the “Best Paying Jobs in America” lists specialties of Medical Doctors as 7 of the 10 highest paying jobs in the United States. 

No discussion of intern and resident salaries would be complete without a disclosure of the average debt these young doctors carry. Because of the high costs of medical school and college tuition, the average medical school graduate owes $241,600 in education debt. The average medical school graduate owes six times as much as the average college graduate. You can’t blame student doctors for wanting to maximize their income as medical interns, residents, and fellows.

If there’s a silver lining in all this, it’s best described in this anecdote from my training years: After completing a 3-year residency in internal medicine, I applied for and was accepted to a second 2-year residency in anesthesiology, a field I was passionate to learn about. In the first weeks of my anesthesia residency, a former chairman of the Stanford anesthesiology department gave us a lecture and tutorial on how to intubate the trachea of a patient with the highest level of skill and ease. I hung on every word he said. I was getting a lesson from a legend, and I was collecting a salary while I was learning this craft. Image a young golf professional getting paid while he received a lesson from Jack Nicklaus. I was earning a salary while I bettered my education and became more marketable in the medical marketplace. Could I have been paid more as a resident? Perhaps. But the primary gain I made during five residency years was the investment of my time in the labor and learning which made it possible for me to work as a board-certified anesthesiologist for the past 36 years . . . and still counting.

I’m confident Stanford Healthcare and the CIF union will negotiate a successful compromise agreeable to both sides. Until that time, stay tuned, as the intersection of physician labor unions and academic medical centers will generate headlines in the days ahead.

I offer this question to my readers: Do you think it’s acceptable for unionized doctors to strike?

REMIMAZOLAM: NEW WONDER ANESTHETIC DRUG OR MEDICAL WHITE ELEPHANT?

THE ANESTHESIA CONSULTANT

In July 2020 the Food and Drug Administration (FDA) approved the intravenous benzodiazepine remimazolam (Byfavo, Acacia Pharma) for use in sedation for procedures of 30 minutes or less. Will anyone utilize this new drug, or is it an expensive addition to our arsenal with few significant advantages over current agents?

Remimazolam differs from midazolam (Versed), the current most commonly used IV benzodiazepine, in that remimazolam is rapidly converted to an inactive metabolite by tissue esterases, resulting in an ultra-short onset/offset profile. Remimazolam is marketed as a powder which must be reconstituted into a liquid within its vial prior to administration.

remimazolam
propofol

For use in procedural sedation, remimazolam will not replace Versed, but rather will aim to replace propofol. The proposed advantages of remimazolam over propofol include:

  1. Remimazolam can be completely reversed by the benzodiazepine antagonist flumazenil (Romazicon) whereas there is no reversal agent or antagonist for propofol. The only way to end the sedative effects of propofol is for an anesthesia professional to support the airway, breathing, and circulation of the patient until the drug effects of propofol wear off in time.
  2. Remimazolam has minimal cardiac or respiratory depression. Sicker ASA III and IV patients maintain their breathing and circulation status while under remimazolam sedation.
  3. There is no accumulative effect of remimazolam over time. Its elimination by an esterase does not slow during lengthy administration of remimazolam, as in the prolonged sedation of an intensive care unit (ICU) patient on a ventilator.
  4. There is no burning sensation upon injecting remimazolam into a patient’s intravenous line as there is with propofol.
  5. A non-anesthesia-professional can administer remimazolam, whereas an anesthesia professional/airway expert must administer and monitor propofol administration.

Are these advantages important? Items 1 – 5 are discussed as follows:

  1. Non-anesthesiologists can reverse the effects of remimazolam with flumazenil if they overdose a patient, but this advantage is less important for anesthesia professionals. Anesthesiologists can manage the airway of a patient over-sedated with a benzodiazepine without need to administer a reversal agent. I’ve never administered a dose of flumazenil in my entire career, nor have most of my anesthesia colleagues. 
  2. Propofol has cardiac and respiratory depression, but in most cases these effects are minimal. Per the PDR (Physician’s Digital Reference), patients with compromised myocardial function, intravascular volume depletion, or abnormally low vascular tone (e.g. septic patients) are more susceptible to hypotension. When an anesthesiologist is present these risks are routinely managed. 
  3. For a long operating room anesthesia case (e.g. of 8 – 10  hours duration), there is no clinically significant accumulation of propofol in the bloodstream. Propofol Infusion Syndrome (PRIS), which can be potentially fatal, is a risk with prolonged propofol sedation in the ICU (See ICU Sedation below).
  4. The burning sensation upon injecting propofol can be blunted by intravenous lidocaine. A 2016 meta-analysis showed that both lidocaine pretreatment and mixing lidocaine with the propofol were effective in reducing pain on propofol injection. In addition, a preanesthetic dose of Versed prevents a patient from remembering any burning sensation from a propofol injection that follows. 
  5. The most important advantage of remimazolam is that non-anesthesiologists can safely administer remimazolam. Propofol administration requires an experienced clinician, e.g. either an anesthesiologist, a certified registered nurse anesthetist (CRNA), or an emergency medicine physician. Per the American Society of Anesthesiologists: “The practitioner administering propofol for sedation/anesthesia should, at a minimum, have the education and training to identify and manage the airway and cardiovascular changes which occur in a patient who enters a state of general anesthesia.” 

The disadvantages of remimazolam compared to propofol include:

  1. Expense. The cost of a 20 ml (200 mg) vial of propofol is $9.20. The cost of a 20 mg vial of powdered remimazolam is $41.67
  2. Remimazolam is sold as a powder and must be reconstituted into a liquid before it can be injected intravenously.

Remimazolam is currently approved as an anesthesia drug in Japan and South Korea, for intensive care unit sedation in Belgium, but only for procedural sedation in the United States, China, and Europe. In total, there are four possible applications for remimazolam. Let’s examine the pros and cons of using remimazolam in these four applications:

  1. Preoperative sedation. Since midazolam (Versed) was approved in 1982, a standard anesthesia practice has included a 2 mg dose of  Versed prior to surgery to calm a patient’s anxiety. In the 1980s my anesthesia chairman at Stanford received a letter from a postoperative patient in which she complained of being awake and very anxious in the operating room prior to the anesthetic for her breast cancer surgery. Our chairman lectured to us, “Do you know many patients are nervous prior to their anesthesia and surgery? Every one of them. We have an excellent drug for relieving preoperative anxiety, and that drug is Versed. Use it! Give your patient a dose of Versed before they enter the operating room. There are few significant side effects of one dose of Versed. Use it!” Will remimazolam replace Versed for this application? No. There is no advantage of the new, shorter acting, more expensive remimazolam over Versed for preoperative sedation.
  2. Sedation for short procedures. This is the FDA-approved application for remimazolam in the United States. An example procedure would be a colonoscopy. Will remimazolam be widely used for colonoscopies in the near future? No, I doubt it. The cost increase is the main disadvantage. See the typical drug acquisition costs for three alternative sedation recipes for colonoscopy below:

            $18.40 for 400 mg of propofol; or 

$5.17 for fentanyl+Versed ($4.35 dollars for 6 mg of Versed  plus $0.82 for 200 micrograms of fentanyl); or

$41.67 for 20 mg of remimazolam

The increased cost per case is $23.27 for remimazolam over propofol

The increased cost per case is $36.50 for remimazolam over fentanyl+Versed.

If a busy endoscopy center does 100 colonoscopies cases per week, the cost increase is $2327 per week for remimazolam over propofol, or $3650 per week for remimazolam over fentanyl+Versed. These are a prohibitive cost increases with no clear added benefits. The only way remimazolam could result in cheaper sedation costs would be if a healthcare system was looking to eliminating the cost of paying for an anesthesia provider for these procedures. The pairing of remimazolam+gastroenterologist sedation rather than propofol+anesthesiologist sedation could afford significant cost savings for a healthcare system.

3. Total intravenous anesthesia (TIVA). TIVA could include a continuous infusion of the ultra-short-acting narcotic remifentanil plus a continuous infusion of the ultra-short-acting remimazolam. An alleged advantage of this technique could be the fast offset time of these two TIVA anesthetic agents. I doubt this technique will gain market share. It’s far easier to turn on the knob of a sevoflurane vaporizer than to load and manage two TIVA-syringe pumps. As well, the added expense of a prolonged infusion of remimazolam will be prohibitive.

4. ICU sedation. Remimazolam has the advantage of ongoing first-degree elimination, meaning that no matter how long the drug is infused, it will always have reliable elimination by esterase and will not accumulate in the plasma. Prolonged ICU sedation with propofol can lead to the Propofol Infusion Syndrome (PRIS). PRIS occurs predominantly in patients receiving high doses of propofol for a prolonged period. Risk factors for the development of PRIS include a critical illness such as sepsis, head trauma, use of vasopressors, and carbohydrate depletion (liver disease, starvation, or malnutrition). PRIS commonly presents as a high anion gap metabolic acidosis, with rhabdomyolysis, hyperkalemia, acute kidney injury, elevated liver enzymes, and decreased cardiac output. Because of the risk of PRIS,  the duration of propofol infusion administration should not exceed 48 hours and the administered dose should not be higher than 4 mg/kg/hour.

This potential advantage of remimazolam over propofol will be offset by the increased expense of hours or days of remimazolam utilization in an ICU sedation situation. ICU sedation with fentanyl and older benzodiazepines such as Ativan will have the advantage of a lower cost. 

In the hands of an anesthesiologist, propofol is an elegant and almost ideal intravenous sedative, with the advantages of rapid onset, rapid offset, inexpensive generic pricing, minimal cardiovascular/respiratory depression, and lack of nausea. Propofol administration does carry the risks of upper airway obstruction, hypoventilation, and low oxygen saturation, but when an anesthesiologist is present these risks are minimal. 

If a healthcare organization doesn’t want to employ an anesthesiologist or a CRNA for a case which requires procedural sedation, then remimazolam may be an excellent sedative choice. Will gastroenterologists prefer to sedate patients with remimazolam plus fentanyl without an anesthesiologist? Or will they prefer to have an anesthesiologist present to administer propofol? Expect gastroenterologists to prefer the latter, because they are not only off-loading the task of sedating the patient, they are also off-loading the risks of managing the patient’s medical co-morbidities, which can be significant if a patient has lung disease, cardiac disease, morbid obesity, or obstructive sleep apnea.

The remimazolam story suggests one of my favorite anecdotes: A former Stanford Chairman of Anesthesiology and friend of mine who left the university in 2006 to become a pharmaceutical company executive, first at Novartis and then at AstraZeneca. Ten years ago, when I asked him what new anesthesia drugs were in the pipeline, he answered, “None, and there probably will be very few new ones. The drugs you have now are inexpensive generic drugs, and they work very well. The research and development costs to bring a new anesthetic drug to market are prohibitively expensive, and unless that new drug is markedly better, it will not push the inexpensive generic drugs out of use.”

Remimazolam will capture a very small market in the United States. Until remimazolam becomes an inexpensive generic drug, I see it as a medical white elephant rather than a wonderful anesthetic advance.

THE ANESTHESIA CONSULTANT

How soon will we see robotic anesthesia in our hospitals and surgery centers? In the past three decades the high-tech revolution introduced the internet, the laptop computer, the iPhone, Google, and global positioning satellites. Most of these discoveries originated in Silicon Valley, just miles outside Stanford University Hospital where I’ve been working for the past 42 years. Our medical world inside the hospital has changed more slowly. We’ve seen advances in noninvasive surgery, fiberoptic scopes, transplantation science, cancer therapeutics, and mega healthcare delivery companies. But what’s new in anesthesia the last 30 years? Relatively little. The Glidescope, sugammadex, ultrasound-guided blocks, and the time-consuming Electronic Medical Record arrived, but we typically administer the same medications, use the same airway tubes, and watch the same vital signs monitors as we did in the 1990s. 

Why have there been no new anesthetics? Let me tell you a story: A former Stanford Chairman of Anesthesiology and friend of mine left the university in 2006 to become a pharmaceutical company executive, first at Novartis and then at AstraZeneca. Ten years ago, when I asked him what new anesthesia drugs were in the pipeline, he answered, “None, and there probably will be very few new ones. The drugs you have now are inexpensive generic drugs, and they work very well. The research and development costs to bring a new anesthetic drug to market are prohibitively expensive, and unless that new drug is markedly better, it will not push the inexpensive generic drugs out of use.”

Is the same true for anesthesia devices? Are proposed anesthetic robots too expensive to design, test, and manufacture? Can they be brought to market to assist current anesthesia providers? Can they be brought to market to replace any anesthesia providers? Keep these economic questions in mind as we review the current science of robotic anesthesia.

vanished and vanishing jobs

Jobs have already disappeared in many industries. ATMs replaced bank tellers. Automated garbage trucks replaced garbage men. In the near future automated cars and trucks will replace drivers. In medicine, computerized artificial intelligence for the analysis of digital images is superior to the human eye, placing the jobs of radiologists, pathologists, and dermatologists in peril. 

Will we live to see anesthesiologists replaced by technology? The following three pictures depict fictional anesthesia robots:

fictional medical robots

But this is what real anesthesia robots look like:

real anesthesia robots

An outline of the types of robotic anesthesia is as follows:

  1. PHARMACOLOGIC ROBOTS
  2. MECHANICAL ROBOTS PERFORMING PROCEDURES
  3. DECISION SUPPORT ROBOTS

  1. PHARMACOLOGIC ROBOTS:

In 2012 a United States national marketing firm contacted me to seek my opinion regarding an automated device to infuse propofol. The device was the Sedasys®-Computer-Assisted Personalized Sedation System, developed by Johnson and Johnson/Ethicon. The system incorporated an automated propofol infusion device, along with standard ASA monitors, including end-tidal CO2, into a device to be used to provide conscious sedation for GI endoscopy.

The SEDASYS system

The Sedasys unit infused an initial dose of propofol (typically 30 – 50 mg in young patients) over 3 minutes, and then began a maintenance infusion of propofol at a pre-programmed rate (usually 50 mcg/kg/min).  If the monitors detected signs of over-sedation, that is, falling oxygen saturation, depressed respiratory rate, or a failure of the end-tidal CO2 curve, then the propofol infusion was stopped automatically.  In addition, the machine talked to the patient, and at intervals asked the patient to squeeze a hand-held gripper device.  If the patient was non-responsive and did not squeeze, the propofol infusion was automatically stopped.

The planned strategy was to have gastroenterologists complete a weekend educational course to learn: that Sedasys was not appropriate if the patient is ASA 3 or 4 or had severe medical problems; that Sedasys was not appropriate if the patient had risk factors such as morbid obesity, a difficult airway, or sleep apnea; and gastroenterologists were taught the airway skills of chin lift, jaw thrust, oral airway use, nasal airway use, and bag-mask ventilation. 

I did not recommend the device be FDA-approved, as I saw the potential of inappropriate patients with obesity or sleep apnea slipping through the screening process, as well as the risk that an over-sedated patient could lose their airway and the gastroenterologist would not be able to rescue them, seeing as propofol has no reversal agent. 

With only one prospective clinical trial, the United States Food and Drug Administration did approve the device in 2013. There was limited clinical use of Sedasys, and Ethicon announced in March 2016 that it was pulling Sedasys from the market. 

The failure of Sedasys was attributed to three factors:

  1. If a patient became too “light” during a procedure, the Sedasys system was not capable of increasing the depth of the sedation.
  2. Both patients and endoscopists expected deep general anesthesia, not moderate sedation. 
  3. Gastroenterologists were ill-equipped to shoulder the responsibility of general anesthesia and airway management. 

From the failure of Sedasys it was clear that further refinement in technology and drug use was needed. That refinement was the development of closed-loop devices. A closed-loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. The cruise-control on your automobile is an example of closed-loop feedback control of driving speed.

In anesthesia, closed-loop devices can infuse the medications propofol and remifentanil, with the rate of the infusions guided by a bispectral (BIS) monitor of EEG (electroencephalography) activity.  Propofol is an ultra-short-acting hypnotic drug, and remifentanil is an ultra-short-acting narcotic. Administered together, these drugs induce total intravenous anesthesia (TIVA).

A closed-loop system can infuse these two drugs automatically. A BIS monitor calculates a score between 0 and 100 for the patient’s level of unconsciousness, with a score of 100 corresponding to wide awake and 0 corresponding to a flat EEG. A score of 40 – 60 is considered an optimal amount of anesthesia depth. A computer controls the infusion rates of two automated infusion pumps containing propofol and remifentanil. The infusion rates depend on whether the measured BIS score is higher or lower than the 40- 60 range. Researchers in Vancouver, Canada expanded this technology into a device called the iControl-RP, where the initials RP stand for remifentanil and propofol. In addition to the BIS monitor, the iControl-RP monitored the vital signs of blood oxygen level, heart rate, respiratory rate, and blood pressure to determine how much anesthesia to deliver.

iControl-RP robot

In a single-blind randomized study published in Anesthesiology in 2015, 42 patients were randomized to the closed-loop iControl-RP group or to a manual group. The results showed the percentage of time with BIS40-60 was greater in the closed-loop group (87%) vs. the manual group (72%). The number of perioperative adverse events and the length of stay in the postanesthesia care unit were similar. The conclusion of the study was that automated control of hypnosis and analgesia guided by the BIS was clinically feasible.

This study led to an article in the The Washington Post in 2015,  in which one of the machine’s co-developers, Dr. Mark Ansermino said, “We are convinced the machine can do better than human anesthesiologists.” The device had been used on 250 patients at that time. The iControl-RP team struggled to find a corporate backer for its project. Dr. Ansermino told The Washington Post, “Most big companies view this as too risky.” He believed a device like this was inevitable. “I think eventually this will happen,” Ansermino said, “whether we like it or not.”

A second pharmacologic robot named McSleepy used three syringe pumps to control the three components of general anesthesia (hypnosis, analgesia, and neuromuscular block) in an automated closed-loop anesthesia drug delivery system. Each component had specific monitoring: BIS; AnalgoScore (an-AL-go-score = a pain score derived from the heart rate and mean arterial pressure) which was used as the control variable to titrate the effective dose of remifentanil; and the train of four (TOF), which was a measure of the twitch strength of a muscle when its peripheral nerve was electrically stimulated.

McSleepy robot

A 2013 study in the British Journal of Anaesthesia  looked at 186 patients managed by McSleepy, in which the McSleepy system showed better control of hypnosis than manually administered anesthesia (see graphs below). 

The control of depth of anesthesia under McSleepy (blue) or manual (green)

The McSleepy system also showed faster extubation times than manually administered anaesthesia. 

A second McSleepy study in the British Journal of Anaesthesia in 2013 showed an application in telemedicine.  The remote control of general anesthetics was successfully performed between two different countries (Canada and Italy). Twenty patients underwent elective thyroid surgeries, with a master-computer in Montreal and a slave-computer in Pisa, demonstrating the feasibility of remote telemedicine control of anesthesia administration.

II.  MECHANICAL ANESTHESIA ROBOTS

Ma’s mask ventilation robot

The first example is a machine designed to provide mask ventilation, as described in the paper “Novel Anesthesia Airway Management Robot for Robot Assisted Non-invasive Positive Pressure Mask Ventilation,” Published by Dr. Ma et al, from China. Ma designed a robot equipped with two snake arms and a mask-fastening mechanism to facilitate trachea airway management for anesthesia. (PIC) The two snake arms were designed to lift a patient’s jaw. The mask-fastening mechanism was used to fasten and hold the mask onto a patient’s face. A joystick control unit managed both the lifting and fastening force. To date this system has not been used on humans, but the device was proposed as a method to perform non-invasive mask positive pressure ventilation via a robotic system.

The Kepler Intubating System

In 2012 Dr. Hemmerling at McGill University in Montreal published a paper in Current Opinions in Anaesthesiology, describing the Kepler Intubation System. The Kepler Intubation System consisted of a remote-control joystick and intubation cockpit, linked to a standard videolaryngoscope via a robotic arm. (PIC) Ninety intubations were performed on a mannequin with this device. The first group of 30 intubations was performed with the operator in direct view of the mannequin. The second group of 30 intubations was performed with the operator unable to see the mannequin. The third group of 30 intubations were performed via semiautomated intubations during which the robotic system replayed a tracing of a previously recorded intubation maneuver. All intubations were successful on the first attempt, with the average intubation times between 41 and 51 seconds for all three groups. The study concluded that a robotic intubation system can complete successful remote intubation within 40 to 60 seconds.

The Magellan Nerve Block System

In 2013 Dr. Hemmerling published the study “First Robotic Ultrasound-Guided Nerve Blocks in Humans Using the Magellan System” in Anesthesia & Analgesia. The Magellan system consisted of three main components: a joystick, a robotic arm, and a software control system. After localization of the sciatic nerve by ultrasound, 35 ml of bupivacaine 0.25% was injected by the robot. Thirteen patients were enrolled. The nerve blocks were successful in all patients. The nerve performance time was 164 seconds by the robotic system, and 189 seconds by a human practitioner. The Magellan System was the first robotic ultrasound-guided nerve block system tested on humans.  

III.  DECISION SUPPORT ROBOTS

A decision-support robot can recognize a crucial clinical situation that requires human intervention and, when allowed by the attending clinician, may administer treatment. It seems likely that cognitive robots which follow algorithms can increase patient safety.

In August 2021 Dr. Alexandre Joosten, an anesthesia professor in Brussels, Belgium and Paris, France, published “Computer-assisted Individualized Hemodynamic Management Reduces Intraoperative Hypotension in Intermediate- and High-risk Surgery: A Randomized Controlled Trial” in Anesthesiology.  This study tested the hypothesis that computer-assisted hemodynamic management could reduce intraoperative low blood pressure in patients undergoing intermediate- to high-risk surgery. This prospective randomized single-blinded study included 38 patients undergoing abdominal or orthopedic surgery. All patients had an indwelling radial arterial catheter to monitor blood pressure continuously. A closed-loop system titrated a norepinephrine infusion based on the blood pressure, and a second separate decision support system infused mini-fluid challenges when low blood pressures were recorded. Results showed the time of intraoperative hypotension was 1.2% in the computer-assisted group compared to 21.5% in the manually adjusted goal-directed therapy group (P < 0.001). The incidence of minor postoperative complications was the same between groups (42 vs. 58%; P = 0.330). The mean stroke volume index and cardiac index were both significantly higher in the computer-assisted group than in the manually adjusted goal-directed therapy group (P < 0.001). The study’s conclusion was that this closed-loop system resulted in a significant decrease in the percentage of intraoperative time with a low mean arterial pressure.

VOICE-ACTIVATED DEVICES

Voice-activated devices are gaining traction in healthcare. The story “Amazon’s Alexa Is Now a Healthcare Provider” was published by Medscape on February 17, 2022.

Alexa at bedside

The article described how thousands of Alexa-enabled devices are in use in hundreds of hospitals in America. Amazon’s Alexa functions as a digital personal assistant whose voice-powered innovation connects patients with their healthcare team members. Patients who are confined to bed can use their voice to communicate directly to a nurse’s smartphone. An Alexa device is positioned near the bed at Cedars-Sinai Medical Center in Los Angeles, making it easy to call for nursing help. (PIC) Alexa can also connect healthcare providers to their patients. Doctors or nurses can appear virtually in a patient’s room on the Alexa Show’s video screen and assess the needs of that patient. I expect voice-activation to link healthcare providers with medical robots in the future.

PROBLEMS WITH ROBOTS REPLACING ANESTHESIA

The medical publications referenced above demonstrate that robotic anesthesia devices exist, yet none of them are in common use at this time. The current and proposed robotic devices are only small steps toward replacing anesthesiologists, because anesthetizing patients requires far more expertise than merely titrating drug levels or performing a solitary mechanical procedure. 

Anesthesia management consists of a wide variety of skills:

  • preoperative assessment of a patient’s medical problems 
  • successful mask ventilation of an unconscious patient (in most cases) followed by placement of an airway tube
  • diagnosis and treatment of any medical complication that occurs as a result of the anesthesia or the surgical procedure
  • removal of the airway tube at the conclusion of most surgeries, and 
  • the diagnosis and treatment of postoperative medical complications

Successful robotic anesthesia devices may eventually eliminate the repetitive aspects of anesthesia management. You may see robots assisting anesthesia providers in the coming decades, depending on the economic viability of the technology. 

Will the intrusion of a robot into anesthesia care be a welcome event? When you’re a patient, do you desire a caring, empathetic human attending to you, or do you desire an algorithm? 

Or in the future, will you desire both?

THE ANESTHESIA CONSULTANT

Underwater general anesthetics of 3 hours duration? See it in The Rescue, a new National Geographic Documentary Film directed by Jimmy Chin (winner of the 2018 Academy Award for Best Documentary Feature for Free Solo)The Rescue details the miraculous extraction of 12 boys and their coach from a flooded Thailand cave in June and July of 2018. The Rescue required 13 underwater general anesthetics delivered by an anesthesiologist and maintained by non-medical cave divers during their 3-hour swim to the mouth of the cave. How did this once-in-history anesthetic tour de force come about? You can watch the movie—a favorite for this year’s Oscar for Best Documentary—on Disney+ for their $7.99 monthly fee. This column explains the specifics as to how anesthesiology innovation saved thirteen lives in The Rescue.

The site of The Rescue was the Tham Luang Nang Non cave in Chiang Rai Province in northern Thailand. Twelve boys of ages 11 – 16 from the Wild Boar soccer team and their coach entered the cave for a birthday celebration. June monsoon rains hit and flooded the entrance of the cave, trapping all thirteen inside. 

The boys were trapped at the left of this diagram. The entrance to the cave is at the right.

The synopsis of The Rescue follows this timeline:

Day 1 – Trials of gas-powered generators to pump the water out of the cave fail to lower the water level.

Day 2 – The Thai Navy Seals arrive on site. They attempt scuba diving into the cave but abort their efforts because of low visibility and difficult access. They were only able to advance 200 meters into the cave. None had experience diving into dark narrow caves. John Volanthen, an information technology consultant who does cave diving as a hobby, shows them a map of the long tortuous cave route, and surmises that the boys are trapped about 2 kilometers into the cave. Richard Stanton, a retired middle-aged British firefighter who is also an expert in cave diving, is alerted to the predicament, and flies to Thailand to help. 

Day 5 – Stanton assembles a collection of his friends who are fellow cave divers. These men have real world jobs such as electricians, contractors, mechanics, and consultants, but are experienced in underwater cave exploration. At first, the Thai Navy Seals will not allow the cave divers to attempt a rescue because they deem it is too dangerous. Eventually the Thai Seals consent to let the cave divers proceed. Stanton describes their passage as scuba diving against a raging river of white water, with the added problem of poor visibility. They surface at the first air-filled chamber inside the cave, and instead of finding the boys they find four pump workers who were unknowingly trapped inside the cave. The cave divers swim the pump workers out, sharing their scuba regulators as they swim, but find the pump workers are easily panicked in the dark cold underwater conditions, and the passage out is very difficult. Their entire swim rescue of these men takes only 30 to 40 seconds, yet Stanton describes the ordeal as “an underwater wrestling match.” 

Day 7 –Rain continues and the water levels rise. Hundreds of people surround the mouth of the cave, and worldwide media coverage is ongoing.

Day 10 – The cave divers continue their attempts to explore the length of the cave. They extend a rope behind them to trace their route back to the outside world. After several hours of traversing the narrow route, including passing through several air chambers above water, they reach a chamber where the atmosphere smells pungent. They fear they have located the rotting flesh of decomposing bodies. Instead they shine a light into the chamber and see 13 people—the Thai boys and their coach—sitting on the rocky floor. They are skinny and frightened, but alive. They’ve had no food for 10 days and have existed by drinking the water from the cave. The cave divers return to the mouth of the cave and announce that the boys are alive. 

Day 12 – The divers follow the rope back to the boys and bring them power gel food and foil blankets. Their plan going forward is unclear. There appears to be no way to swim the boys out for the 3-hour underwater journey to the mouth of the cave. One option is to wait until October (four months) until the monsoon season is over, and the cave is no longer flooded. A second option is to somehow drill down to where the boys are trapped. A third option is to pump out millions of gallons of water out of the cave, but this is also deemed impossible. Another cave diver friend of Stanton’s is Dr. Richard Harris, who lives and works in Australia. Dr. Harris is an anesthesiologist. The team of cave divers telephone him and ask if the boys can be anesthetized for 3 hours to be extracted underwater. His initial answer is no, that this would be impossible.

At the same time, the divers bring an oxygen analyzer into the cave and discover that there is only 15% oxygen left in the atmosphere where the boys are trapped. Normal room air contains 21% oxygen, and 15% oxygen is considered an eminent threat to life for the boys. Immediate action is necessary.

Day 14 – Dr. Harris arrives at the cave. He and his cave diver colleagues come up with a plan to anesthetize and extract the boys, but there is a new problem: The Thai government does not want them to attempt the rescue. The government fears the boys will all die in the futile attempt. Enter Josh Morris,   a cave diver who speaks Thai. He explains the facts and the threat of the low oxygen atmosphere to the government authorities, and convinces them there is no time to waste and that there is no other workable plan. The government agrees to let the cave divers proceed.

Day 15 – The rescue plan is as follows: Divers will swim into the cave to the chamber where the boys are located. The divers will transport an extra oxygen cylinder, a full-face dive mask and regulator, and a dive suit for each boy. They will also carry three medications: 1) Xanax, an oral anti-anxiety pill in the Valium family of benzodiazepines; 2) ketamine, an injectable general anesthetic drug, carried in a syringe-and-needle setup; and 3) atropine, an injectable drug which dries up oral secretions (necessary because ketamine can cause excessive salivation significant enough to choke off breathing). When the cave divers arrive at the chamber where the boys are situated, they dress the first boy in a dive suit complete with a rubber head-covering. Dr. Harris then administers the Xanax pill and the intramuscular injections of ketamine and atropine. After the boy loses consciousness, they tie the boy’s hands behind the boy’s back and apply the full-face oxygen dive mask to keep the water out. The boy is placed in the water atop a full oxygen cylinder, and a diver guides the boy and the cylinder under the water. This diver clings to the rope as he begins the 3-hour journey back toward the cave entrance. There are multiple air chambers on the route back to the entrance. At each air chamber, the diver surfaces and assesses if the boy is still alive and breathing, and whether the boy is anesthetized deeply enough. If the boy is twitching, the diver injects more ketamine. Keep in mind this diver is not a doctor—he has been taught by Dr. Harris to inject more drug if the boy seems to need more sedation. This process is repeated for four boys the first day and is successful. All four reach the surface, alive and anesthetized, and are transported to a nearby hospital.

Day 17 – The process is repeated and four more boys are successfully extracted.

Day 18 – A heavy monsoon rainstorm is expected, so all five remaining individuals are extracted before the cave is totally flooded. The cave divers are hailed as civilian heroes as the last of the boys is rescued. The rescue effort involved more than 10,000 people, including divers, rescue workers, 900 police officers, 2,000 soldiers representatives from 100 governmental agencies, 10 police helicopters, more than 700 diving cylinders, and the pumping of more than a billion liters of water from the caves. 

In the aftermath, Richard Stanton returns to England and receives a George Medal, the second highest award for civilian gallantry, in a regal ceremony at Buckingham Palace. 

The Rescue is riveting and suspenseful, and ultimately worth the one hour 45 minutes and the $7.99 you’ll invest in it.

Here’s the Anesthesia Consultant analysis of the medical circumstances in The Rescue:

  • In an operating room, anesthesia is typically delivered as a gas (e.g. sevoflurane), or intravenously. Neither gas anesthesia nor intravenous anesthesia is possible in an underwater cave rescue. Ketamine is the only general anesthetic drug which can be injected. Ketamine can be injected either into an IV (e.g. in an operating room by an anesthesiologist) or into a muscle (e.g. in a cave in Thailand). Ketamine has the advantages of quick onset and a lack of respiratory depression—that is, ketamine will not stop a patient’s breathing. But if a patient becomes over-sedated it’s possible they will have upper airway obstruction which can lead to inadequate ventilation, so ketamine administration typically needs to be administered by an anesthesia professional who monitors the patient’s breathing—unless you’re rescuing kids in a cave. Ketamine also has theses disadvantages: It results in a relatively slow wake up (compared to propofol and/or sevoflurane gas); it causes markedly increased saliva production (which is why we need to administer atropine, a secretion-blocking anticholinergic drug—along with ketamine); and ketamine can cause vivid bad dreams—for this reason we routinely give an IV benzodiazepine such as Versed along with ketamine. Re-dosing of ketamine was required because the drug’s half-life (the time it takes for the total amount of ketamine in the body to be reduced by 50%) is about 2.5 hours in adults. Dr. Harris couldn’t be with every boy en route, which is why he had to train the other cave divers how to inject ketamine for redosing.
  • Dr. Harris could have chosen to use an injection of intramuscular Versed instead of Xanax (the oral benzodiazepine used in The Rescue). A disadvantage with oral Xanax is its slow onset time. It’s unlikely the Xanax began to work until it was absorbed from the stomach and carried by the bloodstream to the brain, which likely took thirty minutes or more.
  • The choice of full-face dive masks (FFMs), capable of maintaining constant positive airway pressure (CPAP) during the anesthetics, was brilliant. All acute medical care, be it in an operating room, an intensive care unit, an emergency room, a battlefield, or a cave, follows the priority order of A-B-C, or Airway- Breathing-Circulation. The problems of keeping the airway open, as well as keeping oxygenation and ventilation intact, were daunting challenges underwater. There were no research articles and no textbooks to tell the cave divers how to deal with this situation. They used their best strategy and made their best guess, and it was successful. If excessive water had leaked into the mask, a boy could drown. 
full face dive mask

  • Fortunately all the boys and their coach were slender (per the video footage) and had low body-mass-indexes (BMIs). A patient with a low BMI typically has an easy airway, and would have a lower chance of obstructing their upper airway during a 3-hour underwater general anesthetic. An overweight patient would probably not have survived a 3-hour underwater general anesthetic. As well, all the boys and their coach were young and healthy with normal hearts and lungs. If they had been older, with any abnormal cardiac or respiratory function, they may not have survived the 3-hour underwater general anesthetic.
The Thai boys in the cave

  • It’s striking that the boys could survive for two weeks with only water and no food. Hydration is critical—no one can survive two weeks without water—but food was not imperative for this length of time. They survived without calories for two weeks, but humans can only survive for about three days without water.
  • Hypothermia, or low body temperature, was a risk during the underwater rescue. Anesthetized patients have no muscle movement and are unable to generate any body heat in the cold water. The scuba suits and hoods were aimed at minimizing the temperature drop while the boys were anesthetized.
  • No one monitored the vital signs of the boys during their 3-hour underwater general anesthetics. General anesthetics always require monitoring of these parameters: heart rate, oxygen saturation, blood pressure, ECG, respiratory rate, temperature, and end-tidal carbon dioxide expiration. In an underwater cave anesthetic, none of this was possible. Luckily the ketamine anesthesia as administered must have kept all the vital signs within acceptable limits.
  • The oxygen concentration in the atmosphere of the cave was only 15%, far lower than the normal room air concentration of 21% we’re all breathing right now. This oxygen concentration of 15% is roughly equivalent to the oxygen concentration atop a mountain at 10,000 feet of altitude. The boys tolerated the gradual decrease of the oxygen level within the cave from 21% to 15% over 12 days without any brain damage or any damage to a vital organ system. An acute decrease from 21% to 15% may have caused low blood oxygen—hypoxia—and organ damage. During anesthetics in an operating room, anesthesiologists commonly administer at least 40-50% oxygen—a higher concentration than in room air—as an extra margin of safety.

The film The Rescue documents a remarkable feat of emergency medicine and emergency anesthesia care. I recommend you see the movie, and I hope you’ll understand the medical care better because of the discussion presented above.

PRESIDENT BIDEN’S COLONOSCOPY ANESTHESIA

THE ANESTHESIA CONSULTANT

Three days ago, I was giving anesthesia for six consecutive colonoscopy patients. Following my first case, I checked my phone and discovered that the President of the United States Joe Biden was having a colonoscopy at Walter Reed Medical Center that very morning. The headlines stated that for the first time, temporary acting presidential power was being turned over to a woman, Vice President Kamala Harris, during the time of President Biden’s colonoscopy anesthesia.

I mentioned this to the gastroenterologist I was working with that day, and he asked, “How long do you think he will be unable to make decisions as the President? We tell our patients not to drive the rest of the day, and not to make any important life decisions after their general anesthetic. Biden has the most difficult and most important job on Earth. When can he return to duty?”

I answered, “My guess is that he’ll have the same propofol anesthetic we’re administering today. The procedure will last thirty minutes, he’ll begin to awaken five minutes after the propofol is discontinued, and within an hour he’ll feel clear-headed.” The gastroenterologist was dubious that the leader of the free world would be alert enough to resume power only one hour after receiving propofol. Joseph Biden was one day short of his 79th birthday when the colonoscopy took place. Later that morning the news services reported that the President had transferred presidential powers to Kamala Harris at 10:10 a.m. EST and resumed his presidential powers at 11:35 a.m., a mere 1 hour and 25 minutes later. 

The evening after the colonoscopy, comedian Colin Jost of Saturday Night Live joked about Biden’s colonoscopy.  During Weekend Update, Jost reported on Biden’s resumption of all his presidential responsibilities immediately following the colonoscopy, and noted that Biden had just turned 79. “Half the country already thinks he’s senile,” Jost said. “You can’t drop all that on him the second he comes out of the gas.”

A note from an anesthesiologist to the comedy writers: No one uses “gas” for anesthesia for a colonoscopy. The anesthetic is solely from intravenous (IV) drug(s).

I have no specific knowledge of what anesthetic drug regimen the President received for his colonoscopy, but more likely than not he received propofol. Anesthesia for colonoscopy is typically administered so that patients have no awareness during this procedure, a procedure which does not involve surgical pain, but rather involves the uncomfortable entrance of a 66-inch-long flexible hose, one-half-inch in diameter, into their anus, rectum, and colon. 

For the quickest recovery after colonoscopy, one option is no anesthesia at all. Very few patients sign up for a colonoscopy without any intravenous anesthesia. The press reports about Biden’s colonoscopy stated that he had anesthesia, so let’s discount the option that he had the procedure while awake. 

Colonoscopy sedation is typically done with one of two recipes: 1) conscious sedation with a combination of intravenous Versed (generic name midazolam, a benzodiazepine in the Valium family) plus intravenous fentanyl, such that the patient has no memory of the procedure; or 2) intravenous general anesthesia with propofol by continuous infusion or by intermittent boluses so that the patient is unresponsive. The combination of Versed and fentanyl leads to a slower wakeup and recovery than with propofol. The duration of effect of Versed is approximately 30 to 45 minutes after a single dose, with a recovery time of 2 to 6 hours. The duration of effect of IV fentanyl begins within minutes and lasts for 30 to 60 minutes after a single dose. 

Propofol for colonoscopy leads to a quicker wakeup, a quicker discharge home, and less hangover. Virtually every surgical general anesthetic in the United States includes propofol, and anesthesiologists are experts at the administration and pharmaceutical properties of the drug. Propofol is an intravenous nonbarbiturate anesthetic which induces anesthesia quickly and provides a rapid emergence from anesthesia. The onset of action is within 20 – 40 seconds. The anesthesia provider for a colonoscopy will continue administering IV propofol until the procedure is over. A typical colonoscopy will last 20 – 40 minutes, depending on whether the gastroenterologist needs to take extra time to remove any colonic polyps. In Biden’s case, a single 3 mm benign-appearing polyp was identified and removed.

Propofol’s pharmacokinetics are described by two phases:

In the first phase (red curve), the plasma concentration decreases rapidly because the drug redistributes, or spreads, out of the bloodstream into other tissues of the body. The halflife of this fast redistribution is only 2 – 8 minutes, meaning the concentration of propofol in the bloodstream is halved every 2 to 8 minutes. This first phase explains the quick transition to wakefulness up after the drug is stopped. The second phase (black curve) is the elimination of propofol from the body. The half-life time of this elimination from the body is 4 – 7 hours (reference: MILLER’S ANESTHESIA, 9thedition, chapter 23 on Intravenous Anesthetics).

The graph below depicts the timeline after propofol is discontinued. After a one-hour infusion, the concentration of propofol in the blood drops to near zero within 30-40 minutes.

THE PROPOFOL CONCENTRATION APPROACHES ZERO 40 MINUTES AFTER THE END OF INFUSION

The website PDR.net affirms this, stating that “Recovery from anesthesia is rapid (8 to 19 minutes for 2 hours of anesthesia) and is associated with minimal psychomotor impairment.” The PDR also states that “The elimination half-life of 3 to 12 hours is the result of slow release of propofol from fat stores. About 70% of a single dose is excreted renally (by the kidneys) in 24 hours.”

While the President would be awake one hour after receiving 30 minutes of propofol, and the blood concentration would be minimal, it still takes 24 hours for 70% of a single dose of propofol to be excreted by the kidneys. Therefore, one hour after the propofol was discontinued, even though the blood concentration was minimal, a significant amount of the drug would still be in the President’s body.

I’ve had propofol anesthesia for a colonoscopy, and I can attest that I woke up promptly and was in an automobile heading home within 45 minutes after the end of the procedure. I felt alert, albeit a bit woozy, after 60 minutes of recovery time. Did I feel it would have been safe for me to resume my duties administering general anesthetics to patients at that time? No. Would a major American airline allow one of its pilots to fly passengers at that time? No. Would the U.S. Army allow a general to command thousands of soldiers at that time? I doubt it.

One hour after a propofol colonoscopy anesthetic, the President would be awake enough to converse and give a “thumbs up.” Would he be alert enough at that point to make decisions regarding the nuclear football, a potential attack on Taiwan by mainland China, or a terrorist attack on a major United States city? Was this nearly 79-year-old man safe to make all the acute decisions the United States President could have to make, only one hour after discontinuing propofol? 

The Mayo Clinic website states that, “After the exam (colonoscopy), it takes about an hour to begin to recover from the sedative. You’ll need someone to take you home because it can take up to a day for the full effects of the sedative to wear off. Don’t drive or make important decisions or go back to work for the rest of the day.” 

Was Biden fit to run the country 55 minutes after his colonoscopy anesthetic? 

Hmmm. The decision as to whether he was recovered enough to resume running the country . . . was a decision made by President Biden’s doctors on that day.

THE ANESTHESIA CONSULTANT

The American Society of Anesthesiologists (ASA) just published a 2022 update on their ASA Difficult Airway Algorithm Guidelines. The 2022 document is a revision of the 2013 publication “Practice guidelines for management of the difficult airway: A report by the American Society of Anesthesiologists Task Force on Management of the Difficult Airway.” The 2022 ASA Difficult Airway Algorithm Guidelines are 51 pages in total.

The most important changes are identified by examining the 2013 and the 2022 algorithms side by side. Let’s look at the 2013 flow chart algorithm and compare it to the 2022 flow chart algorithm below:

THE 2013 ASA DIFFICULT AIRWAY ALGORITHM

THE 2022 ASA DIFFICULT AIRWAY ALGORITHM

Note these major changes from 2013 to 2022:

  1. The top third of the 2022 algorithm lists factors which direct the anesthesiologist to perform awake intubation. The reason for this change is undoubtably the wisdom of utilizing awake intubation when a significant risk of a difficulty airway exists. There are minimal airway risks when a patient is awake, and the benefit of placing the endotracheal tube in a difficult airway patient while the patient is awake is immense. When we give mock oral board examinations to anesthesia residents at Stanford, and we describe to the examinee that the patient has a difficult airway, the answer of “I’d do an awake intubation” is hard to criticize and almost never leads to a catastrophe. In contrast, inducing general anesthesia prior to intubation in these patients can lead to a “Can’t intubate-can’t oxygenate” emergency, which can lead to a cardiac arrest and possible anoxic brain damage.
  2. The text highlighted in red in the 2022 document is both new and vital. The first of these is “OPTIMIZE OXYGENATION THROUGHOUT,” under the pathway INTUBATION ATTEMPT WITH PATIENT AWAKE, with the footnote 2Low- or high-flow nasal cannula, head elevated position throughout procedure. Noninvasive ventilation during preoxygenation. The message is to keep oxygen flowing via nasal cannula throughout airway management attempts to minimize hypoxia, and to keep the head elevated to maximize the functional residual capacity (FRC), which is the reservoir of oxygen in the patient’s lungs.
  3. LIMIT ATTEMPTS, Consider calling for help” is new and printed within a red box in the INTUBATION ATTEMPT AFTER GENERAL ANESTHESIA –> FAILED pathway. This is an effort to prevent repetitive unsuccessful intubation attempts from soaking up precious time, during which the brain is poorly oxygenated.
  4. LIMIT ATTEMPTS AND CONSIDER AWAKENING THE PATIENT” is new and printed in red in the NON-EMERGENCY PATHWAY under the “Ventilation adequate/intubation unsuccessful” pathway. This is again an effort prevent repetitive unsuccessful intubation attempts from soaking up precious time, during which the brain is poorly oxygenated.
  5. LIMIT ATTEMPTS AND BE AWARE OF THE PASSAGE OF TIME, CALL FOR HELP/FOR INVASIVE ACCESS” is new and printed in red in the EMERGENCY PATHWAY under the MASK VENTILATION NOT ADEQUATE, SUPRAGLOTTIC AIRWAY NOT ADEQUATE pathway. This is again an effort to prevent repetitive unsuccessful intubation attempts from soaking up precious time, during which the brain is poorly oxygenated.

These changes, printed or boxed in red, emphasize that the pace of difficult airway decisions is important. The duration of elapsed time is vital. When an anesthesia provider cannot intubate the patient and then cannot ventilate the patient, the oxygen level in the blood can plummet. There is a significant danger of anoxic brain damage within minutes. I’ve previously reviewed this topic in a 2019 Anesthesia Grand Rounds Lecture at Stanford, summarized in my article “Five Minutes to Avoid Anoxic Brain Damage.” The U.S. Library of Medicine website states that “Brain cells are very sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death,” and “Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later.”

The sentence “Be aware of the passage of time, the number of attempts, and oxygen saturation” appears more than once in the 2022 Difficult Airway Algorithm Guidelines article, and is a key point for all anesthesia providers who encounter a difficulty airway emergency.

In my roles as an anesthesia quality assurance reviewer or a medical-legal expert consultant, I’ve seen this issue arise multiple times. Even though anesthesia providers believe they are following the Difficult Algorithm accurately, they are doing things too slowly, and they waste too much time. Once it’s clear that a “Cannot intubate-cannot oxygenate” scenario is occurring, the time clock is running, and the anesthesia provider must not only do the correct thing but he or she must do the correct thing without undue delay. The necessary procedure may be as invasive as a cricothyroidotomy/front of the neck access via the scalpel-bougie-endotracheal tube approach.  

The five points listed above are the major changes in the algorithm. In addition, the new 2022 article includes a Pediatric Difficult Airway Algorithm and an approach to Extubation of the Trachea in a Difficult Airway Patient. Other important quotes from the 2022 article include (bold emphasis added):

  1. “The consultants and members of participating organizations strongly agree with recommendations to perform awake intubation, when appropriate, if the patient is suspected to be a difficult intubation and difficult ventilation (face mask/supraglottic airway) is anticipated.”
  2. “Meta-analyses of randomized controlled trials comparing video-assisted laryngoscopy with direct laryngoscopy in patients with predicted difficult airways reported improved laryngeal views, a higher frequency of successful intubations, a higher frequency of first attempt intubations, and fewer intubation maneuvers with video-assisted laryngoscopy.”
  3. The footnote (7) for alternative difficult intubation approaches states: 7Alternative difficult intubation approaches include but are not limited to video-assisted laryngoscopy, alternative laryngoscope blades, combined techniques, intubating supraglottic airway (with or without flexible bronchoscopic guidance), flexible bronchoscopy, introducer, and lighted stylet or lightwand. 
  4. “A randomized controlled trial comparing a videolaryngoscope combined with a flexible bronchoscope reported a greater first attempt success rate with the combination technique than with a videolaryngoscope alone.”
  5. When appropriate, refer to an algorithm and/or cognitive aid.” 

AUTHOR’S NOTE: I’d suggest that the Stanford Emergency Manual of cognitive aid algorithms for anesthesia and ACLS emergencies be onsite at all anesthetizing locations. 

I’d also recommend that the 2022 ASA Difficult Airway guideline algorithm be onsite at all anesthetizing locations.

Every anesthesia professional will encounter patients with difficult airways—this is one of the most important and most feared situations in our specialty. Commit the 2022 ASA Difficult Airway Algorithm to memory. Use awake intubation when you’re concerned about the potential of a “Cannot intubate-cannot oxygenate” scenario. And if you’re in the middle of a difficult airway emergency, call for help and be aware of the passage of time, the number of attempts, and the oxygen saturation. Don’t let an excessive number of minutes elapse without regaining oxygenation of your patient.

PHYSICIAN TRAINING: TWO FORKS IN THE ROAD

THE ANESTHESIA CONSULTANT

You’re in the middle of your medical school years, and wondering what specialty to pursue. There are two major forks in the road when trying to choose the career that suits your emotional make-up and work ethic. The sooner you understand these two forks in the road, the better off you’ll be. 

CLINIC DOCTOR OR ACUTE CARE DOCTOR?

The first major fork in the road is whether you’re best suited for a career as a clinic doctor or as an acute care doctor. The main specialties for clinic doctors are internal medicine, family practice, pediatrics, and psychiatry. The main specialties for acute care doctors are surgery, anesthesiology, emergency medicine, and obstetrics-gynecology.

Internal medicine and pediatrics include subspecialties. The subspecialties of endocrinology, oncology, nephrology (kidney specialist), and allergy-immunology are primarily clinic doctors. Cardiologists are hybrid clinic/acute care doctors who must first complete a residency in internal medicine, and then subspecialize with 3-4 additional years of fellowship training. Pulmonologists (lung specialists) are also hybrid clinic/acute care doctors who must first complete a residency in internal medicine, and then subspecialize with 2 additional years of fellowship training.

Pursue a career as a clinic doctor if you enjoy sitting in a room, listening to patients and talking to patients. Most clinic doctors rarely place a tube or a needle into a patient after their residency training is completed. Most clinic doctors work daytime hours, but have weekend call and night call, which may include phone consultations or emergency room visits. Clinic doctors see multiple patients per day, perhaps 4-8 patients per day for psychiatrists, and up to 30 patients or more for some specialists such as allergists.

Pursue a career as an acute care doctor if you prefer adrenaline-charged arenas such as the operating room, the intensive care unit, the labor and delivery suite, or the emergency room. The pace will be much faster than in a clinic, and the stress level will be higher. You’ll perform surgeries, deliver babies, or run trauma Code Blues. If you become an anesthesiologist, you’ll routinely put your patients into pharmaceutical comas and then reverse that status.

These are some of the significant differences between the clinic path and the acute care path:

  1. Sudden risks are almost unknown in clinics. In a clinic setting, doctors make diagnoses, order tests, and prescribe oral medications. In an acute care setting, health care interventions involve scalpels, tubes, IVs, intravenous medications, breathing tubes and ventilators. Malpractice events are less likely to occur in clinic settings. It’s difficult to harm a patient in a clinic. Clinic errors may involve the failure to make the correct diagnosis or the failure to follow up on the result of an important test. Acute care errors can include failure to manage the A-B-Cs of airway, breathing, and circulation safely.
  2. Income differences. Physicians who do procedures, and who incur the risks of procedures gone wrong, earn more money. Physicians who staff clinics usually earn less. This fact may be concealed from medical students. Once students become aware of the income differences, the invisible hand of capitalism tends to drive them into the acute care specialties which are higher paying. The financial numbers are pertinent, because the median debt for an American medical school graduate was $200,000 in 2019. The average four-year cost for a public medical school education was $250,222, and the average four-year cost for a private medical school education was $330,180.  Medical school graduates need to earn a significant income to repay their student loans.
  3. Long-term relationships with patients. Primary care clinic doctors often attend to the same patients for decades, and form long-term cordial relationships with their patients. Acute care doctors typically see a patient once, for a surgery, an anesthetic, a childbirth, or an emergency room visit. Acute care doctors rarely develop lasting interactions with any of their patients. Clinic doctors may receive holiday cards or presents from their patients; acute care doctors will not.
  4. Lifestyle differences. Clinic doctors mainly work daytime hours, although they may receive afterhours phone calls regarding patient health problems. If one of their patients becomes acutely ill, a primary care doctor may see that patient in the emergency room. Some acute care specialists work as shift labor, especially emergency room doctors, anesthesiologists, or hospitalists. Acute care doctors may also have schedules in which they can take blocks of weeks or even months off at a time, giving them the option to pursue longer vacations or travel. Primary care doctors are rarely able to take long blocks of time away from their patients.

ACADEMIC DOCTOR OR COMMUNITY DOCTOR?

A second fork in the road during physician training is the choice whether to become an academic physician or a community physician. An academic physician is a faculty member at a medical school. Their job description includes teaching younger doctors and mentoring younger doctors in patient care. Academic physicians work in university hospitals, Veterans Administration (VA) hospitals, and county hospitals—any setting where medical students and resident physicians are training. Ambitious medical students often plan to become academic physicians, because they admire the academic professors who are training them. Ambitious medical students may profess that they want to become academic professors, because it may appear this career path is what the finest university training programs are looking for. The gambit seems to look like this: if you want to be admitted to a famous university residency program, tell them you want to be a famous professor just like the individual who is interviewing you for that program. I can only advise you to tell the truth about your career ambitions.

Most physicians eventually drift away from academic intentions, and become community physicians. Community physicians are individuals who work at your local clinic, your local hospital, or your local health maintenance organization. A 2017 article stated that “Although 45 percent of graduating medical students aspire to work in an academic setting, only about 16 percent will do so. Of those who do work in academic settings, up to 38 percent will leave academia within 10 years.” 

These are some of the significant differences between the between the academic path and the community path:

  1. Income. Academic physicians usually earn less money than community physicians. Academics spend part of their time teaching young doctors, instead of seeing additional patients. Academics may also spend part of their time doing laboratory science or clinical studies, instead of seeing additional patients. Academic departments also typically pay a “Dean’s tax” to the medical school dean, as part of their agreement within the medical school. 
  2. Housestaff back-up. Academic physicians have a team of housestaff physicians—interns, residents, and fellows—to do many of the mundane tasks of patient care for them. These housestaff physicians may sleep in the hospital and handle middle-of-the night issues while the academic faculty member sleeps at home. This is a significant benefit. I can attest that as you age, you’ll have less and less desire to get out of bed to handle urgent medical issues. Community physicians must function like interns. They set up call schedules to share night duty with other community physicians in the same specialty, but if there’s an issue at night when you’re on call, you will have to drive to the hospital to handle it.
  3. Tenure for professors. If academic professors have a productive career of publishing significant research, their university may award them with tenure, defined as lifetime job security at that university. Tenure guarantees a distinguished professor academic freedom and freedom of speech by protecting him or her from being fired no matter how controversial or nontraditional their research, publications, or ideas are. This benefit is usually only an option for basic science research doctors who are specifically hired to “tenure-track” appointments.

A THIRD FORK:

A small minority of medical school graduates shun either academic or community practice, and instead take their MD degree and go directly to work in industry either as a researcher at a medical company, or a consultant in a medical industry. Consider this path if you believe you’re not suited to taking care of patients.

My Journey:

I had personal experience with each of these forks in my medical education road. During medical school I was having a difficult time deciding between surgery and internal medicine. During my final summer quarter break, I returned to my hometown and joined the local general surgeon to observe him performing a gall bladder surgery. After the procedure, I questioned him about his satisfaction with his career in general surgery. He told me, “I’m very happy with general surgery, but if I had to do the 7-year residency over again, I could never do it. It was that difficult.” The look on his face told me what I needed to know, so I opted for a career in internal medicine. I matched at Stanford and began my three-year residency. During my second year, while I was spending my afternoons in the internal medicine clinic, I realized I preferred acute care to clinic care. That same year I’d spent one month in the Stanford intensive care unit (ICU) rotation. The Stanford anesthesia department ran the ICU, and I met multiple faculty and resident anesthesiologists who loved their specialty and were excellent role models. I made an appointment to meet with the ICU physician-in-chief, and told him I wanted to become an ICU specialist like him. He told me, “If you want to be an ICU doctor, I’d advise you to do an anesthesia residency first, because ICU care involves airway-breathing-circulation, and anesthesiologists are the airway experts. But once you finish your anesthesia residency, you’ll never come back to see me, because you’ll love anesthesia so much you’ll probably just do anesthesiology as a career.” I followed his advice. I applied to anesthesia residencies, and was eventually accepted to begin my anesthesia training, albeit three years into the future.

During those three years, I finished my internal medicine training. Then I hovered at the fork in the road between academic and community medicine during my one-year gap between my internal medicine and anesthesia residencies. The Stanford Department of Internal Medicine hired me for a twelve-month position as a faculty member in the emergency room. My role was to be the attending in the ER from 9 a.m. to 5 p.m. Monday through Friday, and to give a lecture to the residents each morning at 8 a.m. I was thrilled to be on the faculty at Stanford at the young age of 29. I discovered during that year that if you’re an academic doctor/clinician/educator who doesn’t do research, that you have minimal respect within your department. That same year I met many community doctors on their ER duty who were very happy with their work. My conclusion from my one-year academic appointment was that if you enjoyed clinical care, then it was better to just graduate from your training program and go out there and do clinical care in the community. If I’d had the skillset to become a tenure-track academic professor, perhaps I would have pursued a university career, but I did not.

THE BIG PICTURE:

There is tremendous competition to become a physician. Applications to medical school are at an all time high. According to the American Association of Medical Colleges (AAMC), applications increased 18% from 2020 to 2021. Stanford University School of Medicine received 11,000 applications for an admission class of 90 spots.

It’s an honorable and a wonderful career to heal and take care of sick and suffering as a medical doctor. If you’re admitted to an American medical school, you’ll have the choice whether to become a primary care doctor or an acute care doctor. You’ll have the choice to become an academic physician or a community physician. But you’ll have made the most important choice already—to become a medical doctor in the first place.

EMERGENCY AT A SURGERY CENTER

THE ANESTHESIA CONSULTANT

You’re the anesthesiologist assigned to a freestanding ambulatory surgery center (ASC). Are you and the facility prepared for an emergency at a surgery center? Let’s examine this case study:

You meet your first patient of the morning, a 75-year-old female scheduled for lateral epicondylitis release surgery on her right elbow.  You review her medical record and interview her. You discover she had her aortic valve replaced with a small metal valve two years earlier. She is active, although she does experience mild shortness of breath on walking stairs. She is obese, weighing 200 pounds, with a BMI=35. She is on no medications. On physical exam, her vital signs are normal, her lungs are clear, and her heart exam is positive for the clicking sound of a mechanical valve and a 2/6 systolic murmur. She has a thick neck and a large tongue. The surgeon says he will only need to operate for 15 minutes. The patient refuses a regional nerve block, so she’ll need to be asleep.

You attach the standard vital sign monitors, preoxygenate the patient, and induce anesthesia with 150 mg of propofol, 50 micrograms of fentanyl, and 40 mg of rocuronium. You intubate her trachea with a 7.0 tube without difficulty, and place her on a ventilator delivering 1.5% sevoflurane and 50% nitrous oxide.

The patient’s arm is prepped and draped. The surgeon injects 2% lidocaine at the skin incision site, and the surgery begins. Vital signs remain normal with BP=110/70, P=80, and oxygen saturation=99%. The surgery concludes after 17 minutes. You discontinue the sevoflurane and reverse the paralysis with sugammadex. The patient’s blood pressure increases to 150/100 within three minutes. Three minutes later the oxygen saturation drops to 80% and thick frothy fluid bubbles into the endotracheal tube and the circle breathing hoses which connect the patient to the anesthesia machine. The blood pressure is now BP=180/120.

You call for help and attempt to suction the frothy fluid out of the breathing tubes. You listen to the lungs and hear loud rattling rales. You assess that you’re dealing with pulmonary edema (excess fluid in the lungs). The patient’s oxygen saturation drops to 70%. 

A second anesthesiologist responds to your call for help and arrives in the room. You explain what is going on, and while you do, the oxygen saturation becomes unmeasurable and the blood pressure machine fails to give any reading. Your colleague suggests you administer 20 mg of Lasix (furosemide) as a diuretic, and he injects this for you. You continue to ventilate the patient with 100% oxygen, and continue to suction copious fluid out of the patient’s lungs. The ECG monitor descends into a slow agonal rhythm, and when you check the carotid artery at the patient’s neck, there is no pulse. You call a Code Blue and begin CPR compressions on the patient’s chest. After thirty minutes of Advanced Cardiac Life Support (ACLS) drug administration, the pulses have not returned. You have no other therapies to offer, and the patient is declared dead.

Acute pulmonary edema on a chest X-ray

Did this have to happen? No, it did not. In a parallel universe with more competent clinicians, let’s look at how this patient should have been handled:

  1. First off, this case was inappropriate for a freestanding outpatient surgery center. This freestanding outpatient surgery center was located miles from the local hospital, and the hospital resources of an intensive care unit (ICU), respiratory therapists, arterial blood gas analysis, and chest X-rays were not available. The surgery was trivial enough—a brief procedure on the elbow—but the patient had a medical history which was too complex to approve a general endotracheal anesthetic at a freestanding ASC. Typically patients who have had a successful cardiac valve replacement are much improved after their surgery, and complaints of shortness of breath or extreme fatigue—symptoms of inadequate cardiac function—are absent. A 75-year-old patient who complains of shortness of breath on exertion was a poor candidate for anesthesia at an ASC. A pre-operative cardiology consult was indicated, and would likely include an echocardiogram and a stress test. In our parallel universe, the echocardiogram ordered by the cardiologist revealed a small aortic valve diameter—less that one centimeter—and a dilated left ventricle with an ejection fraction (LVEF) of 35% (a severely abnormal value, as the normal left ventricle can eject more than 50% of its volume). This patient with a low LVEF needed to have her surgery postponed until her cardiac function was improved via medications or a further surgical cardiac intervention was done. After that, when and if this elbow surgery ever does occur, it would need to be done in a hospital setting.
  2. What if the anesthesiologist did not adhere to #1 above, and the anesthetic led to pulmonary edema as described above? How could the anesthesiologist better manage the emergency? All acute medical care is managed by A-B-C, or Airway-Breathing-Circulation. In this case the Airway tube was in place. The Breathing was being done by the ventilator, but the breathing tube was occluded by pulmonary edema fluid. The treatment to improve the Breathing was both active suctioning to clear the airway of fluid and medical treatment to reverse the cause of the increased fluid. Diagnosis of the Breathing and Cardiac problems was as follows: discontinuation of anesthesia in this patient, who still had a breathing tube in her trachea as she awakened, stimulated markedly increased blood pressure –> the left ventricle could not eject against this high pressure –> this led to acute left heart failure with resulting backup of fluid into the lungs –> this caused pulmonary edema and dropping oxygen saturation. (Because of her airway anatomy, she was not a candidate for a deep extubation.) Treatment for both the Breathing problem and the Cardiac problem was an emergency afterload reducing drug such as nitroprusside. Every ASC must have a Code Blue cart with emergency drugs and equipment, and the anesthesiologist must call for the cart. He or she instructs one of the RNs to prepare a 250 ml bag of nitroprusside and to attach it to an intravenous infusion pump.
  3. We anesthesiologists are only as good as our monitoring devices. When the oximeter reports very low readings and the BP cuff stops working, we are in big trouble. Anesthesiologists cannot safely administer a potent intravenous infusion such as nitroprusside without an accurate second-to-second monitor of the patient’s blood pressure. One of the anesthesiologists quickly places an arterial line catheter in the left radial artery at the wrist. The arterial line is connected to the monitoring equipment, to reveal that the blood pressure is 240/140, for a mean blood pressure (MAP) of 173 mm Hg. The anesthesiologists connect the nitroprusside drip to the peripheral intravenous line, and infuse the drug to decrease the blood pressure to 140/80 (MAP=100) within minutes. The frothing fluid in the breathing tubes clears, and the oxygen saturation returns to 100%. 
  4. The anesthesiologists then place a central venous catheter in the right internal jugular vein and transfer the nitroprusside infusion to the central line. They titrate small doses of fentanyl and Versed into the peripheral IV line to sedate the patient because immediate extubation is not appropriate, and prepare to transfer the patient via ambulance to the nearest hospital ICU. The original anesthesiologist accompanies the patient in the ambulance to the ICU, while continuing to monitor the patient’s vital signs and manage the blood pressure, sedation, ventilation, and oxygenation.
  5. The patient’s sedation is discontinued the next morning in the hospital ICU, and she is extubated safely. She has no brain damage or cardiac damage. The anesthesiologist visits her that afternoon, and converses with her as she eats her lunch. She has questions about how this could have happened, and he answers each question honestly.

There are multiple take-home messages from this case study:

  1. The preoperative screening of patients at a freestanding ASC is crucial. No one wants to have a Code Blue or a near-Code Blue, miles away from any hospital. Surgery centers manage preoperative screening in various ways, but most community ASCs do not run an in-person preoperative anesthesia clinic. At our ASC, a preoperative caller contacts each patient two days prior to their scheduled surgery, and fills out a comprehensive history form based on the patient’s answers and any medical tests and/or consults available on that patient. If there are positive answers regarding important medical issues such as shortness of breath, chest pain, heart disease, obstructive sleep apnea, morbid obesity, chronic kidney or liver disease, cancer, or previous transplants, then the preoperative caller refers the case to the Medical Director. The Medical Director makes the decision whether the patient is appropriate for the scheduled surgery. If the patient is not appropriate, the case is cancelled two days ahead of time.
  2. If an acute respiratory or cardiac emergency occurs at an ASC, the first move is to call for help from a second anesthesiologist. Two minds and four hands are a better solution. The registered nurses bring a copy of the Stanford Emergency Manual into the room, as well as the code cart which includes the emergency drugs and monitoring equipment.
  3. In a true emergency, diagnosis and treatment must occur within minutes. No anesthesiologist wants to be the doctor who “draws a blank” when their patient is trying to die right in front of them. Stanford’s Dr. David Gaba pioneered acute anesthesia simulator training to improve anesthesiologist performance in emergency settings. You may inquire whether such simulations are available in your geographic area.  
  4. Always manage acute medical emergencies as A-B-C, or Airway-Breathing-Circulation, in that order. In this case the improvement in Breathing required suctioning and afterload reduction, and the improvement Cardiac required arterial line monitoring and afterload reduction.
  5. Realize that short simple surgeries exist, but some short simple surgeries on sick patients present significant anesthetic risks. The anesthesiologist must assess all medical risks and not be swayed by a surgeon who insists this will be “just a short simple case.” If an anesthesiology complication occurs, that surgeon will not likely be blamed, nor will he or she come to your defense. It will be “the anesthesiologist’s fault.”
  6. Every ASC must be prepared for acute unexpected emergencies. The code cart must be stocked with ACLS medications and monitoring equipment for arterial and/or central lines. The ASC should ideally have a copy of the Stanford Emergency Manual, and all drugs and equipment listed in that manual should be available, even though it is not a hospital setting.
  7. It’s important for ASCs to conduct mock-Code-Blue drills on a yearly basis so that staff is prepared when a real emergency occurs.
  8. Depending on cost, an ASC may choose to stock a nitroglycerin drip or a newer potent vasodilator medication such as Cleviprex (clevidipine) rather than nitroprusside in their code cart.
  9. Ideally, anesthesiologists who work at ASCs should also have medical staff privileges at an acute care setting in a hospital, and be performing anesthetics on sicker hospitalized patients there. If an anesthesia provider’s practice is reduced to only healthy patients for outpatient surgeries, that anesthesia provider may become less than competent if a patient develops an emergency in a surgery center.
  10. In case of an emergency at a surgery center, your goal is to stabilize the patient and transfer the patient to the nearest hospital as soon as it is safely possible. The hospital resources of an ICU, respiratory therapists, radiology, cardiology consultation, and a full laboratory service including arterial blood gas analysis are invaluable.

For those readers who are surgical patients, let me reassure you that the vast majority of patients cared for at freestanding ASCs have no anesthesia complications, and many ASCs are staffed by competent anesthesiologists and nurses prepared to save you in the rare event that something goes awry before, during, or after your outpatient surgery.

THE ANESTHESIA CONSULTANT

A South Korean group led by Dr. Y.E. Jang published a study in this month’s issue of Anesthesiology describing the use of a head-mounted smart glasses display during radial arterial line placement in patients younger than 2 years. Placing a catheter into the tiny radial artery in a child’s wrist is one of the most difficult procedures in our specialty. The average internal diameter of the radial artery is 1.2 ± 0.3 millimeter in children aged less than 2 years. Wearing smart glasses improved the anesthesiologist’s first-attempt success rate, and reduced the procedure time and complication rates. This was an important study, and important information.

In the control group of this study, each anesthesiologist would use a traditional ultrasound screen to visualize the artery. 

The anesthesiologist must look up to see the ultrasound machine, while he is working on the patient’s wrist.

In the smart glasses group, the ultrasound machine was located behind the operator, and the smart glasses were paired with the ultrasound machine. The smart glasses used were a binocular Moverio BT-35E unit,  connected to an ultrasound machine by a HDMI cable. The smart glasses displayed a simultaneous replica of the ultrasound screen image in front of the anesthesiologist’s eyes, so the operator could easily see both the procedure field (the radial artery at the wrist) and the ultrasound screen simultaneously without any head and eye movement. 

The anesthesiologist can see the ultrasound image while he is looking at the patient’s wrist

One hundred sixteen children were included in the study. The smart glasses group had a higher first-attempt success rate than the control group: 87.9% (51 of 58) vs. 72.4% (42 of 58) in the control group, with p = 0.036. The smart glasses group also had a shorter first-attempt procedure time (median 33 seconds) than the control group (median 43 seconds), with p = 0.007.

An accompanying editorial in the same issue of Anesthesiology stated, “This elegant prospective trial offers objective insight into the potential impact of head-mounted displays on the overall success and provider ergonomics in anesthetic care during technically complex procedures. Head-mounted displays and augmented reality devices have been evaluated in various settings, including placement of ultrasound-guided peripheral nerve blocks, for use in intraoperative patient monitoring and placement of central venous catheters.”

What will be the role of smart glasses in medicine? We all remember the original hype surrounding the 2013 release of Google Glass, a product which failed to capture a significant market of users. 

Google Glass

Problems with Google Glass included: “The unit overheated frequently with use and shut itself down, the battery life wasn’t long enough (less than an hour), the apps were great demos but limited in scope, and the user interface — tapping, swiping, blinking, head gestures, and the voice recognition after saying ‘Ok Glass’ — was not always smooth.” 

A 2014 study looked at using Google Glass to aid central venous catheter insertion in adults. This study failed to show any positive effects on success rate, procedure time, or number of attempts. These results most likely were due to the fact that larger central blood vessels in adults are easier to locate than the diminutive radial artery in the pediatric population.

Smart glasses are being studied in aviation. Both anesthesiologists and pilots have occupations where the slightest miscalculation or mistake can cost lives. Any step which enhances safety can be seen as a valuable change. A new product called AEROGLASS (Augmented reality aerial navigation for a safer and more effective aviation) attempts to put augmented reality in front of pilots’ eyes.

AEROGLASS in aviation

A recent review states, “The AEROGLASS turnkey smart glass solution provides general aviation pilots a true 3D, 360° view of navigation and safety features. One of the largest challenges for aviation professionals is accurately and safely navigating an aircraft. Current studies show that pilot error accounts for up to 70 % of all aviation accidents. Piloting an aircraft requires translating complex readings from the control panel displayed in 2D into a 3D environment and 360° reality. Accessing this information also requires pilots to take their eyes off the sky, thereby making them more prone to errors and increasing their stress levels. With a headset on, pilots will now be able to have digital 3D information appearing naturally in their field of vision, helping them make faster and better decisions. ‘Our product is an AR solution based on smart glasses. When pilots wear them, they will continue to see the scenery around them, but in addition to that, relevant safety and navigation information will be overlaid transparently within their field of view. . . . At first, the newly developed technology targets professional general aviation, but after some time AEROGLASS plans to utilize its technology in other transportation domains such as automotive and maritime or even for passengers.”

There are two potential uses for smart glasses in anesthesiology. The first is for performing invasive procedures which require ultrasound technology, such as the placement of peripheral nerve blocks or the placement of catheters into arteries and veins. This use makes sense, because it can make some procedures easier, as shown in the Jang study. But the placement of pediatric arterial lines, as in the Jang study, is a small marketplace (e.g. including pediatric open heart surgery, and pediatric surgery involving major blood loss). Ultrasound imaging for the placement of peripheral nerve blocks would be a bigger market, but to date there is no data supporting the use of smart glasses in the placement of peripheral nerve blocks.

Anesthesia vital signs monitor display

A second and more compelling use for smart glasses would be the display of a patient’s vital sign monitoring in real time on the smart glass screen, so that an anesthesiologist is in constant contact with the images of the vital sign electronic monitors. In 2021 a nurse anesthetist publication looked at the use of Google Glass by seven nurse anesthetists for display of the vital signs monitor, but there were no quantitative data to examine the significance of the technology. The physician medical literature has not studied the issue. 

Advantages of using smart glasses for real time patient vital signs monitoring would include:

  • The electrocardiogram, oximeter, and end-tidal CO2 waveforms would be displayed front and center in the anesthesiologist’s sight. The vital signs of heart rate, blood pressure, oxygen saturation, end-tidal gas values, and temperature would be constantly visualized no matter where the anesthesiologist was looking. 
  • This is a futuristic technology, and its use may connote that the hospital or surgery center is at the cutting edge of monitoring and safety equipment (despite the lack of any data to confirm this advantage at this time).

Disadvantages of using smart glasses for patient vital signs real time monitoring would include:

  • The cost of the head-mounted display (Moverio BT-35E, glasses in the current study) is approximately $800. This is not a large amount of money, but multiplied times every anesthetizing site, the expense rises.
  • The requirement for reliable and constant Bluetooth connection between the smart glasses and the electronic monitor.
  • The weight of the smart glasses (119 grams, or 0.43 pounds) is 4 – 8 times heavier than usual glasses (25 – 50 grams, or 0.05 – 0.1 pounds). Many individuals may object to wearing this product. 
  • If an anesthesiologist wears prescription glasses of his or her own, there would be two pairs of glasses needed.
  • The question of whether smart glasses are necessary in every routine anesthetic.

Let’s look at this last point. During most routine anesthetics the constant beep-beep-beep note and tone of the pulse oximeter gives the anesthesiologist real-time audible monitoring of both the heart rate and the ballpark oxygen saturation, without having to look at the display. The anesthesiologist still has to look up at the vital signs screen intermittently to note the blood pressure, end-tidal gas values, and temperature, but this intermittent look is part of the vigilance all anesthesiologists must do anyway. A left-to-right scanning gaze at the patient, the surgical field, the IV lines, any IV infusions, the airway tubing, the anesthesia machine, and the vital signs monitor screen is standard procedure in anesthesiology. If adopted, the use of smart glass technology for routine vital signs monitoring would indeed be a large market. Would the addition of smart glasses for routine monitoring be an overdose of technology in the operating room cockpit? Does excessive technology distract us from the actual patient?

Let me give you a historical perspective. As recently as the year 2000 there were zero computers in the anesthesia workstation. Our equipment included an anesthesia gas machine, a vital signs monitor, and carts which contained breathing tubes, airway equipment, syringes, needles, and drugs. Now we are encumbered by an electronic medical record (EMR) system screen + keyboard, and a narcotic-dispensing computerized drug cart in every hospital anesthetizing location. 

EPIC anesthesia electronic medical record (EMR) computer
Anesthesia drug cart
Anesthesia bar code reader/label printer computer

Add in some smart glasses with Bluetooth connection, and you’ve got an armada of gadgets to both aid the anesthesiologist and to distract him or her from the actual patient, who is three feet away and in need of vigilant care. Is anesthesia care any safer with all the computers: the EMR, and the narcotic-dispensing computerized drug cart? There is no data that these devices have made anesthesia any safer—it is only more complicated.

If smart glasses are ever to become a standard of care, I believe it would require data and proof that anesthesia complications were reduced and anesthesia outcomes were improved with such a device.

Technology in medicine tends to come between the patient and his or her doctor, a theme explored in my 2019 editorial, and in my novel Doctor Vita. View the future of medical technology with care. Think of that computer terminal between you and your doctor during a clinic visit. Now imagine a parallel situation with that computer terminal between you and your anesthesiologist, between you and your emergency room doctor, or between you and your ICU nurse. Will adding more electronic devices lead to safer care or more convoluted care? 

Put it another way: Do we need smart glasses, if we have smart anesthesiologists?

THE ANESTHESIA CONSULTANT

 

Who is responsible for your safety before, during, and after your surgery? Will it be a nurse or will it be a physician? This is an important question. Perioperative mortality is the third leading cause of death in the United States after heart disease and cancer. This statement appeared in the July 2021 issue of Anesthesiology, our specialty’s leading journal.  We’re all aware of the threats from heart disease or cancer, but most people know next to nothing about “perioperative mortality.” What is perioperative mortality? 

The word “perioperative” means “around the time of surgery.” It’s officially defined as the 30-day time period following surgery. “Mortality” means a patient death. Any patient who dies within 30 days of their anesthetic qualifies as a perioperative mortality. Very few patients die in the operating room, but significant numbers die in the weeks that follow. 

Why do patients die? A 2013 study in Anesthesiology states, “Despite the fact that a surgical procedure may have been performed for the appropriate indication and in a technically perfect manner, patients are threatened by perioperative organ injury. For example, stroke, myocardial infarction, acute respiratory distress syndrome, acute kidney injury, or acute gut injury are among the most common causes for morbidity and mortality in surgical patients.”  

The same article states, “a 30-day death rate of 1.32% in a U.S.-based inpatient surgical population for the year 2006. This translates to 189,690 deaths in 14.3 million (1 in 75) admitted surgical patients in one year in the United States alone. For the same year, only two categories reported by the Center for Disease Control—heart disease and cancer—caused more deaths in the general population.” Note this data was for inpatient surgeries.

The practice of anesthesiology is currently defined as “perioperative medicine.” At Stanford University, we’re called the Department of Anesthesiology, Perioperative, and Pain Medicine. Perioperative medicine refers to the care of patients before surgery (preoperative), during surgery (intraoperative), and after surgery (postoperative). Each of these three areas is critical in assuring the lowest rate of complications. The American Board of Anesthesiology requires each candidate for board certification to pass an oral exam with clinical questions pertaining to preoperative, intraoperative, and postoperative management. A board-certified physician anesthesiologist is therefore validated as an expert in all areas of perioperative medicine.

Who will make YOUR anesthetic decisions? Who will take care of you before, during, and after YOUR surgery? 

Most anesthetics are conducted by physician anesthesiologists. At times, physician anesthesiologists employ certified registered nurse anesthetists (CRNAs) to assist them in what is called the anesthesia care team (ACT) model. In this model, an MD anesthesiologist supervises up to four CRNAs who work in up to four different operating rooms simultaneously. All the responsibility in the ACT model resides with the supervising MD anesthesiologist.  

In a minority of states (19 of the 50 states) in America, governors made it legal for an unsupervised CRNA to provide anesthesia care. Are CRNAs and anesthesiologists equals? No, they are not. The difference in training is profound. CRNAs are registered nurses with a minimum of one year experience as a critical care nurse followed by, on the average, an anesthesia training period of three yearshttps://www.aana.com/membership/become-a-crna/minimum-education-and-experience-requirements  Physician anesthesiologists have to graduate from a four-year medical school or osteopathic  school, and then complete four additional years of internship and residency to become board-eligible anesthesiologists. The initial rationale for unsupervised CRNA care was that some rural communities had inadequate supplies of MD anesthesiologists, so governors made the decision to let nurses supply the anesthesia care unsupervised. These states include Arizona, Oklahoma, Iowa, Nebraska, Idaho, Minnesota, New Hampshire, New Mexico, Kansas, North Dakota, Washington, Alaska, Oregon, Montana, South Dakota, Wisconsin, California, Colorado, and Kentucky. If you live in one of these 19 states, there’s no guarantee a perioperative physician anesthesiologist will care for you. 

Does the lack of a perioperative physician—an anesthesiologist—make a difference? Yes. 

Doctor J H Silber’s landmark study from the University of Pennsylvania documented that both 30-day mortality and failure-to-rescue rates were lower when anesthesia care was supervised by anesthesiologists, as opposed to anesthesia care by unsupervised nurse anesthetists. Silber wrote, “These results suggest that surgical outcomes in Medicare patients are associated with anesthesiologist direction, and may provide insight regarding potential approaches for improving surgical outcomes.”

In 2009, in California where I live and work, Governor Arnold Schwarzenegger signed a law permitting independent practice for CRNAs. California physician anesthesiologists have been angry and concerned about this legislation change, but in the 12+ years since the law went into effect, the penetration of unsupervised CRNA practice in California was been minimal. This is despite the fact that there is an oversupply of CRNAs in the western United States.   

The traditional older models of physician-only anesthesia or the anesthesia care team are still the dominant modes of practice in California. 

Anesthesiology is the practice of medicine. Perioperative medicine is the practice of medicine. Anesthesiology and perioperative medicine are the domains of physicians. 

When you are a patient in an intensive care unit (ICU), all orders and decisions are made by physicians. Nurses are an essential part of ICU care, but management is by physicians. 

When you are a patient in an emergency room (ER), all orders and decisions are made by physicians. Nurses are an essential part of ER care, but management is by physicians.    

Why should your perioperative medicine be managed by non-physicians?

A major conflict is playing out in American medicine at this time. Beginning in 2025, all CRNAs will need a doctorate in nurse anesthesia to enter the field. Expect these nursing graduates to introduce themselves to you as “Doctor.” This new degree, called a “Doctor of Nursing Anesthesia Practice (DNAP),” is not a medical school diploma, and by no means is equivalent to the Medical Doctor (MD) degree held by physician anesthesiologists. Medical school admission in America is extremely competitive. For the 2020-2021 year there were 53,030 medical school applicants, and 22,239 applicants were admitted, meaning only 42% of medical school applicants matriculated. 

The American Association of Nurse Anesthetists (AANA) has made the decision to deceive patients by formally changing its name to the American Association of Nurse Anesthesiology, confusing the distinction between an MD anesthesiologist and a nurse anesthetist by adopting the word “anesthesiologist” to describe themselves. 

The American Society of Anesthesiologists (ASA) released this statement: “The American Society of Anesthesiologists condemns AANA’s organizational name change and encouragement of its members’ use of the term “nurse anesthesiologist,” which will confuse patients and create discord in the care setting, ultimately risking patient safety.” The ASA statement also said:

  • ASA, the American Board of Anesthesiology, the American Board of Medical Specialties and the American Medical Association affirm that anesthesiology is a medical specialty and professionals who refer to themselves as “anesthesiologists” must hold a license to practice medicine.
  • The New Hampshire Supreme Court upheld a ruling in March 2021 by the New Hampshire Board of Medicine to limit the use of the term “anesthesiologist” to individuals licensed to practice medicine.
  • The Council on Accreditation of Nurse Anesthesia Educational Programs defines “anesthesiologist” as a doctor of medicine (M.D.) or doctor of osteopathy (D.O.) who has successfully completed an approved anesthesiology residency program.
  • The World Health Organization views “anesthesiology as a medical practice” that should be directed and supervised by an anesthesiologist.

Who will be taking care of YOU before, during, and after your surgery? As patients, you deserve to know, and you also deserve a physician managing your perioperative medicine. 

Before your surgery, you deserve a medical doctor.    

After your surgery, you deserve a medical doctor.    

And yes . . . during your surgery, you deserve a medical doctor of anesthesiology as well.

CARDIAC ARREST DURING A PEDIATRIC TONSILLECTOMY

THE ANESTHESIA CONSULTANT

A 12-year-old boy and his mother walk into a surgery center. The child is scheduled for a tonsillectomy, and is otherwise healthy. The anesthesiologist induces general anesthesia, and ten minutes later the patient has ventricular arrhythmias which descend into a cardiac arrest. Advanced Cardiac Life Support (ACLS) measures are applied, but the child cannot be resuscitated, and is declared dead. What caused this cardiac arrest during a pediatric tonsillectomy?

This is an actual closed malpractice case which I was asked to review. The anesthesiologist induced general anesthesia with propofol and a paralytic drug called succinylcholine (sux-in-ol-KOH-leen), and then inserted a breathing tube successfully into the patient’s windpipe. All vital signs were normal. Sevoflurane, nitrous oxide, and 50% oxygen were ventilated into the patient’s lungs. The surgeon began the tonsillectomy. One minute later the cardiac arrest occurred. The anesthesiologist followed ACLS guidelines, but standard ACLS treatments and hyperkalemia (elevated potassium concentration) treatments were unsuccessful.

Succinylcholine is an intravenous muscle relaxant (paralytic) drug commonly used in the United States. Succinylcholine is an old drug—available since 1951—which has the distinction of being the most rapid-acting intravenous muscle relaxant, and also the shortest-acting muscle relaxant. Succinylcholine is an important drug in an anesthesiologist’s toolkit. When an airway emergency threatens a patient’s life, such as the unexpected occurrence of laryngospasm, succinylcholine is the emergency drug of choice to paralyze the patient, relax the spasm of the vocal cords, and enable the anesthesiologist/emergency room physician/acute care physician to insert a life-saving breathing tube into the trachea.

But succinylcholine can be a dangerous drug. The Food and Drug Administration (FDA) placed a Black Box Warning on succinylcholine in 1994. The current succinylcholine warning in the PDR (Prescribers’ Digital Reference) reads:

Succinylcholine is contraindicated in patients with a personal or familial history of malignant hyperthermia and/or skeletal muscle myopathy. Malignant hyperthermia may be precipitated by succinylcholine; concomitant use of volatile anesthetics may further increase this risk. 

In neonates, infants, children, and adolescents, reserve the use of succinylcholine for emergency intubation or instances where immediate securing of the airway is necessary (e.g., laryngospasm, difficult airway, full stomach, or lack of intravenous access). 

There have been rare reports of ventricular dysrhythmias and fatal cardiac arrest secondary to rhabdomyolysis with hyperkalemia, primarily in healthy-appearing pediatric patients who were subsequently found to have undiagnosed skeletal muscle myopathy, most frequently Duchenne’s muscular dystrophy. 

Affected pediatric patients are typically, but not exclusively, males 8 years or younger. Although some patients have no identifiable risk factors, a careful history and physical exam may identify developmental delays suggestive of myopathy, and a preoperative creatinine kinase could identify patients at risk. 

Closely monitor body temperature, expired CO2, heart rate, blood pressure, and electrocardiogram in pediatric patients to help detect early signs of malignant hyperthermia and/or hyperkalemia. 

The rhabdomyolysis syndrome often presents as peaked T-waves and sudden cardiac arrest within minutes of succinylcholine administration. If cardiac arrest occurs immediately after succinylcholine administration, institute treatment for hyperkalemia (e.g., intravenous calcium, bicarbonate, glucose with insulin, hyperventilation). If malignant hyperthermia is suspectedinitiate appropriate treatment (e.g., dantrolene, supportive care) concurrently.”

Per the Black Box warning, succinylcholine has the potential for inducing life threatening hyperkalemia in children with undiagnosed skeletal muscular dystrophies. Severe hyperkalemia and ventricular arrhythmias followed by cardiac arrest may occur in apparently healthy children who have an occult muscular dystrophy (usually Duchenne’s muscular dystrophy). An occult muscular dystrophy is a rare inherited disease. The global prevalence of Duchenne’s muscular dystrophy is 7.1 cases per 100,000 males, and 2.8 cases per 100,000 in the general population. The Black Box warning on succinylcholine recommends to “reserve use in children for emergency intubation or need to immediately secure the airway.”

The Black Box warning applies to neonates, infants, children and adolescents. No parent wants their son or daughter under the age of 18 to electively receive a drug which has an FDA Black Box Warning for use in adolescents. No parent wants their neonate, infant, child, or adolescent to have a risk of sudden cardiac arrest under general anesthesia for a common elective surgery.

In 1994 the Anesthesia Patient Safety Foundation (APSF) published a sentinel article about the risks of succinylcholine in pediatric anesthesia. The article reviews the history of the succinylcholine warning: “In 1992, Drs. H. Rosenberg and G. Gronert published a letter in Anesthesiology briefly reviewing four deaths in male children under the age of eight who had received halothane and then succinylcholine. These cases were identified through the Malignant Hyperthermia (MH) Hotline. Reference was also made to ‘11 similar cases’ identified through the German MH Hotline. Their letter concluded with the statement: ‘We have notified the Food and Drug Administration of this potential problem and recommended that anesthesiologists carefully consider the indications for use of succinylcholine in young children.’ This letter was accepted for publication August 24,1992.” The article goes on to emphasize “the need for prompt and appropriate treatment should hyperkalemic arrest occur. This treatment involves the intravenous administration of calcium. With proper treatment, approximately 50% of patients have survived this catastrophic hyperkalemia.” The Black Box warning specifically states, “If cardiac arrest occurs immediately after succinylcholine administration, institute treatment for hyperkalemia (e.g., intravenous calcium, bicarbonate, glucose with insulin, hyperventilation).”

Despite the Black Box warning, how often is succinylcholine still used for non-emergency pediatric anesthetics in the United States? No one knows. I can attest that during a recent Quality Assurance review in the Northern California, I saw anesthetic records from a board-certified anesthesiologist who administered succinylcholine to a 14-year-old boy for elective ear surgery. I discussed this with the anesthesiologist, who was unaware they were doing anything dangerous.

There is an excellent alternative to the elective use of succinylcholine. For most cases, pediatric or adult, the muscle relaxant rocuronium is a superior alternative to succinylcholine. Succinylcholine is the IV muscle relaxant with the most rapid onset, but large doses (0.9 mg/kg) of rocuronium are nearly as rapid as succinylcholine, without any of succinylcholine’s risks.   Succinylcholine is also the IV muscle relaxant which wears off the fastest, but since the year 2015 FDA approval of the muscle relaxant reversal drug sugammadex (Bridion), an intubating dose of rocuronium can be rapidly reversed within 3 minutes by administering 16 mg/kg of sugammadex

Succinylcholine remains an important drug for the treatment of airway emergencies. I would never begin a general anesthetic if I did not have a vial of succinylcholine immediately available in case of an airway emergency. In addition, succinylcholine is important because it can be administered intramuscularly (in a patient who has no IV). For example, if a child is undergoing an inhalational induction of general anesthesia with sevoflurane vapor prior to a surgery, and the child suddenly goes into laryngospasm before any IV can be started, (this does occur, not uncommonly, and is a true emergency), the appropriate treatment is an intramuscular injection of 4 mg/kg of succinylcholine. The child will become paralyzed within minutes, and the anesthesiologist can then insert a life-saving breathing tube. (The mean onset of paralysis with 4 mg/kg intramuscular succinylcholine in children ages 1 to 10 ranges from 2.9 to 3.9 minutes.)

I’ve written about the advantages and risks of succinylcholine previously in the article, “Succinylcholine: Vital Drug or Obsolete Dinosaur?”  

I also refer you to the published article, “Is There Still a Role for Succinylcholine in Contemporary Clinical Practice?

The take home messages from this case study of a cardiac arrest during a pediatric tonsillectomy are:

  • If you’re an anesthesia provider, do not administer succinylcholine to a neonate, infant, child, or adolescent for an elective surgery. The Black Box warning on succinylcholine recommends to “reserve use in children for emergency intubation or need to immediately secure the airway.”
  • If you’re a parent, prior to your son or daughter’s surgery, be empowered to ask your child’s anesthesiologist if they’re aware of the Black Box warning on succinylcholine. 
  • Nobody wants a death brought on by an elective anesthetic.

HAL from the movie 2001:A Space Odyssey

In 2004 I began writing Doctor Vita, a novel describing the encroachment of Artificial Intelligence (AI) into medical care. Fifteen years later, in 2019, Doctor Vita was published. The story described Artificial Intelligence in medicine as a perceived panacea that descended into a chaotic dystopian reality.

In recent years, engineers have developed closed-loop AI machines that can administer appropriate doses of anesthetics without human input, as described in The Washington Post article, “We Are Convinced the Machine Can Do Better Than Human Anesthesiologists.”

This month’s issue of Anesthesiology, our specialty’s leading journal, contains two studies on further incremental Artificial Intelligence in Medicine advances in the operating room. Both studies reveal machines that control a patient’s blood pressure automatically during surgery, by the administration of fluids and/or vasopressors (Joosten, et al. and Maheswari et al. 

Closed-loop anesthesia computer controllers for AI titration of anesthesia level

Two editorials accompany these publications. In the first editorial, titled “Computer-assisted Anesthesia Care: Avoiding the Highway to HAL,”  author Dr. David Story writes, “Among the cautionary tales of computer-assisted human activity, 2001:A Space Odyssey is a standout. On a journey to Jupiter, HAL the computer kills most of the crew, forcing the survivor to deactivate HAL. Like space travel, while computer-assisted health care has great potential it also contains the full Rumsfeld range of knowns and unknowns.” Dr. Story concludes his editorial with, “As our pilot counterparts are doing in aviation,anesthesiologists should anticipate training in crises while using computer-assisted technologies, as well as maintaining the skills to ‘fly’ manually.  . . . None of us wants to manage a deteriorating patient by trying to deactivate a malfunctioning computer-assisted anesthesia system, only to have it respond, ‘I’m sorry . . . I can’t do that.’

The second editorial in the same issue of Anesthesiology is titled “Back to the OR of the Future: How Do We Make It a Good One?”  Author Dr. Martin London writes, “The classic 1985 science fiction film Back to the Future transports the erstwhile protagonist (Marty McFly, played by a young Michael J. Fox) 30 years backwards into the past in the eccentric ‘Doc’ Brown’s custom DeLorean time machine, to deal with a series of comedic yet moral quandaries regarding his future existence. A notable quote by Doc Brown is, ‘The future is whatever you make it, so make it a good one.’  Dr. London goes on to say, “The use of artificial intelligence–derived controllers clearly signals a new era in intraoperative hemodynamic management. . . . It does seem inevitable that software control of hemodynamics and anesthetic depth will become routine. Thus, we might ask, ‘What happens to the operator/clinician involved?’ Will it be more appropriate for a busy anesthesiologist covering multiple operating rooms to be supervising the admittedly extreme scenario of ‘information technology experts’ ensuring the machines are functioning properly or actual healthcare providers monitoring the patient and not the machine? And what happens when the “computers go down”? Who will rush in to fill the gap? Will the process be ‘good’ or will it be ‘dystopic?’

Artificial intelligence in medicine is not the stuff of science fiction. AI in medicine is here. Will Artificial Intelligence in medicine assist doctors in compassionate care of their patients, or will AI present one more set of computers obstructing the relationships between healing professionals and those who need healing?

Medical journals like Anesthesiology reveal the future of medicine, as published data unfolds. A novel like Doctor Vita reveals a fictional future of medicine, based on the very trends that are going on today. 

Do you want a computer to care for you when your life is on the line? Do you want an algorithm, or a human, to be your doctor?  

Will you have a choice?

HOW LONG DOES GENERAL ANESTHESIA LAST?

THE ANESTHESIA CONSULTANT

“I’m going to have surgery to have my gall bladder out. How long will the anesthesia last?”

The query “How long does general anesthesia last?” is a common question before surgery. Modern anesthetics wear off quickly after surgery, but the answer to your question is “It depends.” It depends on: (1) which drugs were administered, (2) the length of the anesthetic time, (3) the type of surgery you had, (4) how much pain you have following the surgery, and (5) how healthy you are.

Let’s look at each of these factors:

  • WHICH DRUGS WERE ADMINISTERED.

The main classes of general anesthetic drugs are intravenous (IV) and inhalational.

IV DRUGS. The most common IV drugs include propofol and narcotics. 

Propofol is a hypnotic drug that renders people unconscious in seconds. A single dose of propofol wears off quickly, within minutes, because the molecules of propofol redistribute throughout the body, to wherever the bloodstream takes the propofol. Organs such as the brain, heart, liver, and kidneys receive high blood flow. Muscle and fat receive less blood flow. If propofol is continuously infused into your IV by a pump or a drip, propolol levels can remain nearly constant. When the infusion is stopped, the propofol concentration in the bloodstream drops, and the drug redistributes back from the brain, heart, live, and kidneys into the bloodstream once again. As the propofol concentration in the brain drops, you begin to awaken. When a propofol infusion is stopped, for most patients, within 10-15 minutes the propofol concentration in the bloodstream will decrease to 10-20% of its previous concentration. Intravenous anesthesia is well discussed in the textbook Miller’s Anesthesia, Ninth Edition, Chapter 23.

SEE ABOVE: For a bolus of propofol at time 0, the concentration peaks in less than one minute, and drops below the Therapeutic range by 8 minutes, meaning the patient will awaken.

Fentanyl is the most common IV narcotic used in surgery in the United States. Narcotics blunt pain, but will not keep you asleep unless administered in very high doses. When fentanyl or any IV narcotic is administered, its blood level is at its highest immediately, and then the blood concentration decreases just like propofol did, by redistributing throughout the rest of the body.

SEVOFLURANE VAPORIZER

INHALATIONAL DRUGS. Sevoflurane is the most commonly used potent inhalational anesthetic. Sevoflurane has both a quick onset and a quick offset time when ventilated into or out of your body. When your surgery ends, your anesthesiologist will turn off the sevoflurane in your inhaled gas mixture, and 90% of the sevoflurane is typically ventilated away in the first 10-15 minutes. Inhalational anesthesia is well discussed in the textbook Miller’s Anesthesia, Ninth Edition, Chapter 20.

Per the left graph, 80-90% of sevoflurane or N2O concentration is exhaled after 10 minutes time

Nitrous Oxide (N2O) is a commonly used anesthetic gas of modest potency. By itself, N2O cannot produce a general anesthetic. It is typically used in a concentration of 50%, as an adjunct to sevoflurane or narcotics. The advantages of N2O are that it is inexpensive, it wears off quickly, and it has a reliable safety record. Dentists sometimes use N2O to bring on inhaled sedation when they are doing office procedures such as filling a cavity.

Balanced anesthesia: Most general anesthetics include balanced doses of propofol, sevoflurane and a narcotic. How fast you wake at the end of your general anesthetic after a surgery depends on the sum total of how much propofol, sevoflurane, fentanyl (or other narcotic) you were given. Higher drug doses –> slower wakeup. Lower drug doses –> faster wakeup.

  • THE LENGTH OF THE ANESTHETIC TIME.

If you have a brief thirty-minute anesthetic to repair a tendon defect in your hand, you’ll wake up quickly, because the doses of the IV and inhalational drugs discussed above will be lower than if you had an eight-hour surgery.

  • THE TYPE OF SURGERY YOU HAD.

Surgeries differ in terms of the amount of anesthetic required. A colonoscopy, for example, is technically not a surgery, but rather an endoscopic examination of the inside of your colon. There is no incision, there is usually only moderate discomfort, and there is no significant postoperative pain. The only anesthetic required may be an infusion of propofol alone, and when that infusion is stopped, you’ll wake in 5 minutes. In contrast, if you have an open heart surgery, such as coronary artery bypass grafting (CABG), the anesthetic plan may be to keep you asleep for several hours after the surgery in the ICU, or even overnight, while your heart, lungs, blood pressure, and temperature recover from the surgery. For the gall bladder excision surgery you’re scheduled for, the typical anesthetic and surgery duration is about two hours. The anesthetic plan would be to turn off the IV and inhaled anesthetic drugs at the conclusion of the surgery, leaving just enough narcotic concentration in your bloodstream so you will awaken with excellent pain control. The duration of this wakeup from when the anesthetics are turned off until you are awake and talking will be 10 – 20 minutes for most patients.

  • HOW MUCH PAIN YOU HAVE AFTER THE SURGERY.

Some surgeries do not hurt. For example, a small breast biopsy is relatively painless. In contrast, an intraabdominal operation such as removal of a portion of your colon will cause much more pain in the hours and days following surgery. Even though 90% of the propofol and sevoflurane will wear off in the first two hours after abdominal surgery, you’ll require ongoing doses of narcotics such as morphine or Dilaudid to be comfortable. Ongoing narcotics cause sedation, and you’ll be sleepy for the duration of time that you require IV narcotics for pain relief.

  • HOW HEALTHY YOU ARE.

All else being equal, patients with normal heart and lung function, and normal body weight, will awaken sooner than patients with decreased heart function, decreased lung function, and/or obesity.

***THE ROLE OF LOCAL ANESTHETICS***

One last topic is the role of local anesthetics to speed anesthetic wakeup and recovery. Local anesthetics such as lidocaine, ropivicaine, or bupivacaine can be injected via needles to effect pain relief. There are several ways this can be done:

  1. Local infiltration of the anesthetic into the skin incision, into the joint if you’ve had an arthroscopy, or into the tissues surrounding the surgical site. Local infiltration directly decreases pain in that region, and therefore decreases the amount of general anesthesia drugs needed or narcotic drugs needed. 
  2. Spinal or epidural blocks, administered by the anesthesiologist into the low back, cause the loss of sedation in the abdomen, pelvis, and lower extremities. This directly decreases pain, and therefore decreases the amount of general anesthesia drugs or narcotic drugs needed. 
  3. Ultrasound directed regional nerve blocks administered by the anesthesiologist, can effect numbness in a shoulder, upper extremity, knee, leg, or foot enervated by a specific nerve. This decreases the amount of general anesthesia drugs or narcotic drugs needed. 

Some examples of how long it takes to wake up, if you’re healthy, after general anesthesia for common procedures:

Colonoscopy                                                    5 minutes

Knee arthroscopy                                            5-10 minutes

Tonsillectomy                                                  5-15 minutes

Breast augmentation                                      10-15 minutes

Abdominal/flanks liposuction                        10-15 minutes

Rhinoplasty/nose surgery                               10-15 minutes

Laparoscopic abdominal surgery                  10-20 minutes

Total knee/hip replacements                         10-20 minutes

Brain surgery/craniotomy                              15-25 minutes

Open heart surgery                                        2 – 12 hours

DYING UNDER GENERAL ANESTHESIA

THE ANESTHESIA CONSULTANT

You’re an anesthesiologist and you’re contacted by a patient who is dying of cancer. He wants an end of life anesthetic so that he will be unconscious and die without pain and suffering. What do you do? Will you enable dying under general anesthesia?

A recent article from the United Kingdom discussed this topic of end of life anesthesia, otherwise known as “terminal anesthesia.” Terminal anesthesia refers to a situation when a patient has a terminal illness such as end-stage cancer and is suffering through their last days. They request to have a general anesthetic so they are unconscious throughout the process of dying under general anesthesia.

Is anyone doing terminal anesthesia anywhere? The Journal of Medical Ethics reported that in 2016, France passed a law granting terminally ill patients the right to continuous deep sedation until death. This right was proposed as an alternative to euthanasia and was presented as the ‘French response’ to problems at the end of life. The law draws a distinction between continuous deep sedation and euthanasia.” 

Euthanasia, or the ending of life through pharmacologic intervention, is illegal in the United States, the United Kingdom, and most nations. In the 1980s and 1990s, Dr. Jack Kevorkian of the United States  infamously created a euthanasia machine that injected lethal doses of sodium pentothal (a hypnotic sleep drug), potassium chloride (an overdose of potassium which caused cardiac arrest), and pancuronium (a paralyzing drug) into terminal patients who requested a pharmacologic suicide. Dr. Kevorkian was convicted of second degree murder, and served 8 years of a 10-to-25-year prison sentence.

Dr. Jack Kevorkian and his euthanasia machine

Dying patients may have an interest in terminal anesthesia. In a survey of 500 individuals in the United Kingdom regarding end-of-life options, 88% of the respondents said they would like the option of a general anesthetic if they were dying.  

What would terminal anesthesia look like? Medication(s) would be administered through an intravenous line to bring on unconsciousness without hastening death. These last three words are key, because terminal anesthesia is specifically not to be euthanasia. Terminal patients are frail, and their cardiac and respiratory systems will be sensitive to oversedation. Terminal anesthesia is not to directly stop the patient from breathing, stop their hearts from beating, or put them at risk from aspirating food into their lungs. The duration of the IV sedation/anesthesia must be maintained until the patient’s heart eventually stops because of their underlying terminal medical illness. Because of the danger of food aspiration into the windpipe (trachea), tube feedings to the stomach during the time of this terminal anesthetic would not be allowed. 

What drugs could be used for terminal anesthesia? Propofol (an IV hypnotic drug) and midazolam (an IV benzodiazepine also known as Versed) are the most likely agents. The initial infusion of these drugs must be gradual, because bolus doses of these powerful agents into the bloodstream of a frail, end of life patient, could easily halt their breathing and hasten death. No pulse oximetry or other monitors would be used, and the person administering the drug would not remain in constant attendance with the patient. These two facts—the lack of monitoring and the lack of being physically present to attend to the patient—are boldly in defiance of what anesthesiologists do when they administer general anesthesia to patients. The motto of the American Society of Anesthesiologists is “Vigilance.” Terminal anesthesia implies minimal vigilance, and for this reason I cannot imagine the practice being approved in the United States.

An April 2021 publication in the journal Anaesthesia disagrees. The authors describe end of life anesthesia as “an impending development for which the specialty should prepare.” Co-author Jaideep Pandit, MD, professor of anesthesia at Oxford University, said, “Ethically, it is the right thing to do to make this offer to dying patients where it is technically feasible and the literature says it is. The desire to be unconscious in times of great adversity is understandable—it isn’t surprising or wrong to want to be unconscious in adverse situations. We as physicians are here to help, and if we have the means to help and meet the patient’s desire and it is ethical to do so, then we should strive to make this option feasible.” This article described the first use of end of life anesthesia as occurring over 25 years ago: “The first description of using general anesthesia in end‐of‐life care was in 1995 by John Moyle, a consultant anesthetist and palliative care physician. Moyle recognized the limitations of conventional approaches . . . Moyle developed a protocol for infusing the then relatively new anesthetic agent propofol and described its use in two patients, who died peacefully after 4 and 9 days of continuous infusion. . . . Moyle and others recommended very slow intravenous infusion by a pump at a carefully titrated dose (e.g. just 5 mg.h‐1 vs. the 100–200 mg typically used as a bolus) The depth of anesthesia achieved was inadequate for a surgical procedure, but was ideal for an undisturbed dying patient.” 

A study from Sweden described their experience with propofol for end of life sedation. Two indications for using propofol were identified. The first was refractory nausea and vomiting, and the second was the need for palliative sedation due to refractory anxiety or agitation, with or without intractable pain. Monitoring of the patient was as follows: “During the first hour of treatment, the patients were checked repeatedly by both the nurse and the physician caring for the patient. Then, evaluation was performed after 2, 6, and 12 hours. These assessments were preferably made by the physician, but when symptom control had been established, the evaluation was made by the nurse. Patients on continuous treatment with propofol were thereafter evaluated at least twice daily by the nurse in addition to their daily routine care. The physician visited the patient at least once daily for evaluation.” The mean dose range of propofol during treatment was between 0.90 and 2.13 mg/kg/h, (or for an average 70-kilogram patient, between 70 and 150 mg of propofol per hour). The length of treatment with propofol varied between 2 hours and 44 days. The study reported “All but three patients died at the unit, and the median survival was 38 days, compared with the usual median survival of 14 days at the unit.” 

Euthanasia is illegal, but general anesthesia is legal. Could general anesthesia really be approved so that individuals do not have to experience the suffering of dying? What if the United States passed a law, similar to the 2016 law in France, that granted terminally ill patients the right to continuous deep sedation until death? Will this type of terminal sedation/anesthesia ever happen in the United States? It’s currently common to utilize anesthesia/deep sedation for patients who are on ventilators in an intensive care unit (ICU). If such a patient has an untreatable illness, they may die while they are in the ICU under deep sedation, but the application of terminal anesthesia outside of an ICU is not seen in the United States today.

There are other ethical, medicolegal and practical implications to utilizing terminal anesthesia. Who would give the IV sedation/general anesthesia? The Hippocratic Oath states, “I will not give a lethal drug to anyone if I am asked, nor will I advise such a plan,” so it’s unlikely any American physician would administer the anesthetic. Would the medical malpractice court system litigate that cases of terminal anesthesia were indeed euthanasia, and therefore illegal? If the American Society of Anesthesiologists opposed the idea, could continuous deep sedation at end-of-life ever come to fruition? What if some medical professional with a license to administer anesthesia decided to open up a practice of administering terminal anesthetics? Could such an individual collect cash payments or insurance payments for administering general anesthesia to patients who were on hospice, and thereby earn a large quantum of money for each case? 

Everyone fears dying, and no one wants to have a painful or torturous death. Expect to hear more discussion about this topic in years to come, but don’t expect physician anesthesiologists in the United States to prescribe or administer terminal anesthesia any time soon.

THE ANESTHESIA CONSULTANT

Who is responsible for your anesthetic? A doctor or a nurse? On March 28, 2021 the anesthesia world in the United States was rocked by the headline: “Wisconsin Hospital Replaces All Anesthesiologists With CRNAs.“  

The hospital was Watertown Regional Medical Center, located in Watertown, Wisconsin,  population 23,861, midway between Milwaukee and Madison. The medical center previously had an anesthesia staff that included both MDs and CRNAs (Certified Registered Nurse Anesthetists).  Why did this change happen? The article didn’t say. The article did say that “Envision, a large medical staffing agency that works with the hospital . . . will oversee the anesthesiology team. A quote from the Medscape article read: “Adam Dachman, MD, a surgeon at the hospital, speaking for himself, said he has no problem using nurse anesthetists. (He said) ‘It’s a misconception that physicians are required to administer anesthesia.’” 

Is this a watershed moment for the profession of physician anesthesiologists? Are CRNAs going to replace MD anesthesiologists all over America, changing the profession forever?

In a word, no. 

Will certified registered nurse anesthetists (CRNAs) will be major factor in anesthesia care in the 21st century? Yes. See this link. There are roles for both CRNAs and physician anesthesiologists in the 21st century. 

Let’s step back and look at healthcare practitioners from the view of a patient. Let’s say you’re a patient, and you enter a medical clinic for a checkup. An individual who is not a doctor interviews you, it’s usually quite clear by their nametag and by their verbal introduction whether they are a physician, a nurse, a physician assistant, or a nurse practitioner. Each of these job titles has a different educational background, a different duration of training, and a differing level of autonomy and responsibility. If a physician assistant or a nurse practitioner presents themselves as your healthcare provider in a clinic, you realize you are not being attended to by a physician.

When you enter a hospital or surgery center for a surgery and an anesthesia professional approaches you prior to your surgery, that professional could be a physician anesthesiologist, a Certified Registered Nurse Anesthetist, or an Anesthesia Assistant (AA). Each of these job titles has a different educational background, a different duration of training, and a differing level of autonomy and responsibility. If a CRNA presents themselves as the sole anesthesia professional responsible for evaluating you and making the anesthesia plan and carrying out all the anesthesia care,  you realize you’re not being attended to by a physician.

Are CRNAs and anesthesiologists equals? No, they are not. The difference in training is profound. CRNAs are registered nurses with a minimum of one year experience as a critical care nurse followed by, on the average, an anesthesia training period of three years. Anesthesiologists are medical doctors, and their training of four years of medical school followed by a minimum of four years of anesthesia residency following makes them specialists in all aspects of anesthesia care and perioperative medicine.

Physician anesthesiologists frequently employ CRNAs to assist them in the anesthesia care team model. In this model, an MD anesthesiologist supervises up to four CRNAs who work in up to four different operating rooms simultaneously. The responsibility for the anesthesia care in this model resides with the supervising MD anesthesiologist. 

The American Society of Anesthesiologists STATEMENT ON THE ANESTHESIA CARE TEAMAnesthesiology is the practice of medicine including, but not limited to, preoperative patient evaluation, anesthetic planning, intraoperative and postoperative care and the management of systems and personnel that support these activities. . . . This care is personally provided by or directed by the anesthesiologist.”

Governors in 19 primarily Western states (Wisconsin, Arizona, Oklahoma, Iowa, Nebraska, Idaho, Minnesota, New Hampshire, New Mexico, Kansas, North Dakota, Washington, Alaska, Oregon, Montana, South Dakota, California, Colorado, and Kentucky) have signed legislation allowing CRNAs to opt out of physician supervision and practice anesthesiology alone. The primary motivation for this change was the fact that hospitals in rural communities had inadequate numbers of physician anesthesiologists. Empowering CRNAs to work alone made surgery more accessible to patients in these rural areas. I have no personal connection to or communication with the Watertown Regional Medical Center, but a small community like the one in Watertown Wisconsin likely was unable to recruit or retain a full lineup of MD anesthesiologists, so they were forced to staff with CRNAs. The Watertown Regional Medical Center website, under “Find a Doctor,” as of April 25, 2021 listed 3 MDs and 10 CRNAs.  

Is there any data that CRNA anesthesia care is less safe than MD anesthesia care?  There is. Doctor J H Silber’s landmark study from the University of Pennsylvania documented that both 30-day mortality and failure-to-rescue rates were lower when anesthesia care was supervised by anesthesiologists, as opposed to anesthesia care by unsupervised nurse anesthetists. This study has been widely discussed. The CRNA community dismissed the study’s conclusions, citing that the Silber study was a retrospective study. 

An anesthesia blog, Great Z’s, recently posted a column titled CRNAs Take Over AmericaThe column said, the anesthesia care team model will be the end of physician anesthesiologists. With the ACT model, anesthesiologists’ roles become more like physician assistants. We’re outside the operating rooms, dealing with preop history taking, starting IV’s, making sure the patients are ready for their surgeries. Meanwhile, the CRNAs are the ones that are administering the anesthesia. They are the ones the surgeons will interact with 90% of the time. Our interactions with surgeons diminish to the point where they feel the CRNAs are doing all the work and no physician anesthesiologist is needed. This makes the hospital administration’s decision to save money by firing all the anesthesiologists that much easier and less controversial with the staff.” 

I disagree that MD anesthesiologists will be pushed out the doors nationwide. Easy anesthetic cases can be done by either MDs or CRNAs, but complex cases (open heart surgery, brain surgery, neonatal surgery, surgery on patients with multiple medical comorbidities) will nearly always require physician anesthesiologists. I believe surgeons will support the role of physician anesthesiologists in their operating rooms. Surgeons have no incentive to replace physician anesthesiologists with CRNAs. Patients have no incentive to replace physician anesthesiologists with CRNAs. Would CRNA anesthesia care be less expensive? There is a paucity of data to support that, with only one study to date, published in a nursing journal (Journal of Nursing Economics) which concluded that, “CRNAs acting as the sole anesthesia provider cost 25 percent less than the second lowest cost model.” 

In California where I live and work, Governor Arnold Schwarzenegger signed the independent practice for CRNAs into law in 2009. California physician anesthesiologists were angry and concerned about the legislation change at the time, but in the 12+ years since 2009, the penetration of unsupervised CRNA practice in California was been minimal. The traditional old models of physician-only anesthesia or the anesthesia care team are still the dominant modes of practice in California. 

One threat that remains troubling is the specter that national staffing companies (see the Watertown story above) may force out MDs and hire predominantly CRNAs, collect the standard anesthesia fees for each case, pay the CRNAs less than they paid MD anesthesiologists, and therefore increase profit to the shareholders of the parent company. What can anesthesiologists do about this problem? Don’t sell your anesthesia practice to a national company. But if your hospital CEO makes an exclusive contract with such a company, it’s possible you could be forced out without any choice.

CRNAs will have a significant role in American healthcare in the future. The most significant role will be played with an MD anesthesiologist at their right hand supervising them. Non-supervised CRNAs will be found mainly at rural hospitals. I don’t see a significant number of unsupervised CRNAs working in Palo Alto, Manhattan, or Boston anytime soon.

The future for physician anesthesiologists still looks bright.

THE ANESTHESIA CONSULTANT

Was Tiger Woods driving under the influence (DUI) on the morning of February 23rd, 2021 when he was injured in a single car accident? 

Perhaps his anesthesiologist knows. 

Tiger Woods underwent surgery at Harbor-UCLA Medical Center just hours after his single car rollover vehicle crash. Surgeons performed a pinning of a tibia (shin bone) fracture and pinning of an ankle fracture. Prior to administering an anesthetic, it would be important for the anesthesiologist to know the toxicology screen results in any patient who just survived such an accident. The anesthesiologist needs to know what other drugs, if any, were present in the patient’s system at the time of the crash, because this fact could influence anesthesia management. Drug use could mean central nervous system depressants (opioids, alcohol, sedatives, hypnotics, sleeping pills) or stimulants (cocaine, amphetamines). If sedative drugs were present, there can be a synergistic effect between the drugs and the anesthetic medications. If stimulant drugs were present, the patient may have tolerance and/or increased anesthetic dose requirements. 

A 2017 anesthesia study stated that “for optimal patient care through the perioperative period, it is critical to obtain information about patient drug use and other associated treatment in order to construct an appropriate anesthetic plan, including specific considerations during surgery, emergence, and in the post anesthesia care unit.” 

In a study from Nature, 1007 consecutive patients undergoing emergency surgery were screened for illicit drug use (IDU). Seventy-five patients (7.45%) were found to be positive for IDU, even though zero patients admitted a positive history of illicit drug use. Of the 75 patients, 50 tested positive for morphine, 22 tested positive for methamphetamine, 13 tested positive for ketamine, 6 tested positive for two drugs, and 2 tested positive for all three drugs. The study concluded, “Knowledge of illicit drug users (IDUs) is important because of the comorbidity related to drug use.”

Miller’s Anesthesia (9th edition, 2020, Chapter 31, Preoperative Evaluation, authored by Wijeysundera and Finlayson) states, “A patient with a history of current or previous alcohol or drug addiction presents special challenges for the perioperative team. . . . Addictive disease should be considered permanent even in patients who have had long periods of abstinence. . . . Substance abuse disorders are risk factors for poor outcomes in the perioperative setting.”

The 1996 Health Insurance Portability and Accountability Act (HIPAA) prohibits a patient’s doctors from divulging any private healthcare information (PHI) to anyone who is not caring for that patient. The anesthesiologists may know whether a motor vehicle accident patient was part of a DUI incident, but they will not release the results of such a tox screen to the press. 

The sheriff who arrived at the Woods crash scene stated there was no evidence that Woods was impaired or intoxicated at the time of the crash in Rolling Hills Estates, California. The police said they “did not issue a citation for Woods . . . To issue a ticket for reckless driving would require evidence that Woods had committed multiple violations before the crash, such as unsafe lane changes, or passing other cars unsafely, according to investigators. . . . Woods had no recollection of the collision, investigators said at the press conference.” 

I’m not a lawyer, but I presume that tox screen results could be subpoenaed if a crime had been committed. For example, if an automobile collides with a school bus and kills someone, then I presume the driver’s medical test results would be part of a criminal investigation. 

According to the forensic report, Tiger Woods was speeding as fast as 75 miles per hour, or more than 45 mph faster than the legal speed limit before his SUV crashed. Investigators said the accident was “the result of Woods driving in an unsafe manner for road conditions. . . . The evidence suggested the golfer didn’t brake or steer out of the emergency for nearly 400 feet after striking an eight-inch curb in the median.” 

Per Golfweek magazine: “forensic experts say the evidence suggests Woods was not conscious when he left his lane and kept going in a straight line before crashing. Instead of staying with the downhill road as it curved right, he went straight over the curb in the median to the left, hit a wooden sign and kept going in a straight line into opposing traffic lanes before leaving the road, hitting a tree and rolling over. Jonathan Cherney, an accident reconstruction expert and former police detective who walked the scene, told USA TODAY Sports it was ‘like a classic case of falling asleep behind the wheel, because the road curves and his vehicle goes straight.’ There were no skid marks on the road, Villanueva said. Instead, Woods’ Genesis SUV kept going straight for several hundred feet. Woods later told sheriff’s deputies he couldn’t remember how the crash occurred and didn’t remember even driving.” 

Per USA Today: “’The report doesn’t deal with the underlying cause of the crash,’ said Charles Schack, a former New Hampshire state police trooper who is now president of Crash Experts, which analyzes traffic accidents for law firms and insurance companies. ‘It addresses the data superficially with no apparent curiosity as to why Tiger drove for hundreds of feet without adjusting his steering, braking, or speed. Taking away the high-profile aspect of this crash and looking at the data and roadway, it appears that the driver made no attempt to follow the roadway during the moments leading to the crash. This is typical of a driver who was incapacitated due to a medical issue, falling asleep or being impaired.’” 

Can an individual take a sleep medication prescribed by a physician, such as Ambien, at nighttime and still have drowsiness from the medication which impairs their driving ability the next morning? Yes. In 2013 the Food and Drug Administration released the following Safety Communication regarding zolpidem (Ambien):

The U.S. Food and Drug Administration (FDA) is notifying the public of new information about zolpidem, a widely prescribed insomnia drug. FDA recommends that the bedtime dose be lowered because new data show that blood levels in some patients may be high enough the morning after use to impair activities that require alertness, including driving. Today’s announcement focuses on zolpidem products approved for bedtime use, which are marketed as generics and under the brand names Ambien, Ambien CR, Edluar, and Zolpimist.

FDA is also reminding the public that all drugs taken for insomnia can impair driving and activities that require alertness the morning after use. Drowsiness is already listed as a common side effect in the drug labels of all insomnia drugs, along with warnings that patients may still feel drowsy the day after taking these products. Patients who take insomnia drugs can experience impairment of mental alertness the morning after use, even if they feel fully awake. 

FDA urges health care professionals to caution all patients (men and women) who use these zolpidem products about the risks of next‐morning impairment for activities that require complete mental alertness, including driving. 

There appears to be a public safety concern that individuals who take Ambien for sleep may be impaired when driving a vehicle the following morning. 

Was Tiger Woods impaired on the morning of his single car accident? I don’t know, and it’s not my intent to accuse him in any way. I wish him a speedy and complete recovery, and hope we can all watch him play golf at a high level once again. The purpose of this column is to inform readers that: 1) anesthesiologists need to know the results of blood and/or urine toxicology screens before they are administer general anesthesia to an automobile trauma victim; 2) sleeping aids such as Ambien (zolpidem) carry an FDA warning that they can impair activities such as driving the morning after administration; and 3) HIPAA law prevents physicians from disclosing the medical records of patients to the media.

A MORBIDLY OBESE PATIENT WITH MEAT STUCK IN HIS ESOPHAGUS

THE ANESTHESIA CONSULTANT

You’re the anesthesiologist on call on a Saturday night. A patient arrives at the Emergency Room complaining that he ate piece of steak one hour ago, and the meat got stuck in his throat. He is morbidly obese patient who stands six feet tall and weighs 350 pounds, for a BMI of 47.

The attending general surgeon wants to do an upper GI endoscopy to extract the piece of meat from the patient’s esophagus or push it through into the stomach. He’s called on you to do the anesthetic. 

What do you do?

You examine the patient and find he has a short neck, a small mouth, and a large tongue. You cannot see his soft palate at all, and you rate him as a Mallampati 4.

Mallampati Class IV airway

The patient is alert, and is an excellent historian. He cannot even swallow his saliva. He has no difficulty breathing or significant chest pain. His hospital chart shows no past anesthetics, and he has no medical problems except hypertension which is treated with lisinopril. His vital signs are normal, and his oxygen saturation is 96% on room air.You are six months out of anesthesia training and new to this hospital. The surgeon—a 60-year-old male with the brash confidence of General Patton—is an iconic and respected figure at this medical center. He wants to proceed at once. It’s 8 pm on a Saturday night. He requests “just a little sedation” so he can insert the endoscope past the gag reflex and into the esophagus.

You bring the patient into the endoscopy suite, attach the standard vital signs monitors, and administer oxygen via a Procedural Oxygen Mask (POM, made by Mercury Medical).

You administer 2 mg of Versed and 100 micrograms of fentanyl IV. The surgeon sprays Cetacaine into the patient’s mouth for topical anesthesia and inserts a bite block. After five minutes time the patient is still wide awake. The surgeon looks at you and says, “I need him a little deeper than this.” You administer another 1 mg of Versed and 50 micrograms of fentanyl. After another five minutes time, the patient is still wide awake. The surgeon looks at you and repeats, “I need him a little deeper than this.” He says this in an impatient condescending tone, and you feel pressured. You administer 50 mg of propofol, and the patient’s eyes begin to drift closed. The surgeon inserts the gastroscope, after which the patient coughs, gags, and vomits into his airway. His oxygen saturation which had been 100% quickly plummets to 75%. You move to the head of the bed, suction the patient’s mouth, and attempt bag-mask ventilation without success. His oxygen saturation drops to 60%. You reach for a Miller 3 laryngoscope and attempt to intubate the trachea, but you cannot visualize his vocal cords. You are panicked. The surgeon is screaming at you to do something. You tell the surgeon he needs to do a tracheostomy. In the meantime you insert a laryngeal mask airway into the patient’s throat, but are still unable to ventilate the lungs. The ECG rhythm converts to ventricular fibrillation, and you call a Code Blue.

After thirty minutes of CPR and ACLS, the patient is declared dead.

What went wrong here? A patient who walked into the hospital is now dead. The basic problem was that the anesthesiologist proceeded to deeply sedate a patient with a full stomach (a known aspiration risk) without first controlling the airway by inserting an endotracheal tube. This morbidly obese patient with a thick neck, a small mouth, and a large tongue was always going to be difficult to intubate, but a successful intubation was most likely to occur under controlled circumstances with the patient awake prior to any endoscopy. The issue of a domineering surgeon pushing an inexperienced anesthesia provider into doing the wrong anesthetic is a key problem. This can and does happen, and once the case has concluded with a bad outcome, that same surgeon will deny any culpability, step back and say “I don’t do anesthesia. The decisions and actions of the anesthesiologist caused the problem, not me.”

How should the anesthetic have been done? 

In a parallel universe, an experienced anesthesiologist would do the following:

  • Explain to the surgeon and the patient that the meat stuck in the esophagus presents a dire risk of aspiration into the lungs and loss of airway, and explain to them that the case must be done either entirely awake without sedation (unlikely to be successful), or as a general anesthetic with an endotracheal tube placed prior to any endoscopy intervention.
  • This case is best done in an operating room, rather than in an endoscopy suite.
  • The anesthesiologist will assemble all emergency airway equipment, including a Glidescope, a fiberoptic laryngoscope, the entire difficult airway cart, and the scalpel, bougie, tube equipment for an emergency cricothyrotomy. 
  • The anesthesiologist will likely call in a second pair of experienced hands, either a second anesthesiologist or perhaps the in-house emergency room physician most experienced with intubating patients.
  • A rapid sequence intubation with propofol, succinylcholine, and cricoid pressure is a possible approach, but runs the risk that if the airway is so difficult that the endotracheal tube cannot be passed on the first attempt, the patient will be difficult to ventilate, difficult to oxygenate, and the meat and saliva from the esophagus could aspirate into the airway, leading to a hypoxic emergency.
  • A safer approach is an awake oral intubation using a fiberoptic laryngoscope. The back of the operating room table is inclined upward into a sitting position. Topical anesthesia and local nerve blocks of the airway are performed. See the footnote below (referenced from Miller’s Anesthesia) for a detailed description of the airway anesthesia.A Moderate sedation with Versed and fentanyl is administered, but the patient is kept awake. There’s still a risk that the topical anesthesia will blunt the cough reflex if the patient regurgitates the meat, so suction and a MaGill forceps are immediately available.
  • The anesthesiologist inserts the fiberoptic scope through an endotracheal tube (ET tube) and advances the scope into the mouth until he or she is able to visualize the vocal cords. This can be difficult and may take time, but there is no acute emergency, so an unhurried approach is warranted. Once the fiberoptic scope is threaded through the vocal cords, the patient will most likely cough violently and will require some restraint by two individuals, one on each side of the bed. The ET tube is threaded over the scope quickly and the balloon on the ET tube is inflated. The tube is connected to the anesthesia machine circuit and end-tidal CO2 is confirmed. At this point an IV bolus of propofol and rocuronium is administered to induce general anesthesia. 
  • Once the ET tube is taped securely in place, the surgeon can position the patient as he desires for the upper GI endoscopy. Anesthesia is maintained with sevoflurane and oxygen. When the surgeon is finished, the patient is awakened using sugammadex as necessary to reverse the muscle relaxation. When the patient opens his eyes, he can be safely extubated.

What are the lessons to be learned from this case study?

  • Don’t be intimidated or pushed into an unsafe anesthesia plan. Do what you were trained to do in residency, and stick to safe anesthesia practice. If an adverse outcome occurs, claiming the surgeon made you do something unsafe will not help you one bit. You are in charge of all anesthesia decisions.
  • In anesthesia practice and all acute medicine care, you must manage Airway-Breathing-Circulation (A-B-C) in that order. Anesthesiologists are trained as airway experts, and for this reason we are the most vital acute care physicians in a medical emergency. The airway must managed first.
  • Take great care when anesthetizing a morbidly obese patient. They are at higher risk for anesthetic complications. They are also at greater risk for surgical and perioperative medical problems. See the lay press coverage in U.S. News and World Report, and also another post from this blog.
  • Maintain your skills in awake intubation. No anesthesiologist uses awake intubation often. For nearly every patient the appropriate sequence is to induce anesthesia first and intubate the trachea afterwards. But some patients: e.g. those with ankylosing spondylitis, congenital airway deformities like Treacher Collins syndrome, or certain patients with morbidly obesity or super morbidly obesity (BMI > 50), awake intubation is indicated. One of my professional partners, a former Senior Examiner for the American Board of Anesthesiologists, told me that during national anesthesia oral board examinations, when a patient presented with severe airway abnormalities for a surgical case, it was very common for successful examinees to state they would perform an awake intubation. Why? Because an awake intubation burns no bridges. The patient is unharmed by general anesthesia until the ET tube is already in place, and thus is unlikely to have a Cannot Intubate-Cannot Ventilate situation that can lead to life-threatening hypoxia. And as well, in an oral exam the examinee doesn’t have to actually perform the procedure—they only have to state they could do it successfully.
  • How do you maintain your skill in awake intubation? This is the tough question. When I was in residency training, Dr. Phil Larson, a former Chairman of Anesthesia at Stanford and former Editor-in-Chief of the journal Anesthesiology, taught us elective awake intubation on patients with normal airways, who did not require an awake intubation, so we could hone the skill. Each patient was sedated with IV narcotics. Local lidocaine nerve blocks were done, and an injection of local anesthetic was administered through the cricothyroid membrane, all prior to us performing the awake fiberoptic intubation successfully. Did this take extra time? It did. The intubation and anesthesia induction took ten minutes instead of one minute. Did the surgeons mind? They didn’t, because they respected Dr. Larson, they were glad an excellent anesthesiologist was attending to their cases, and they realized that nine minutes of time was no big deal. Am I recommending you do this in your practice? No, but in this age of the Glidescope, many anesthesiologists have forgotten how to utilize a fiberoptic intubation. I recommend you practice fiberoptic intubation on asleep patients, and maintain the skill.

You may need it to save someone’s life one day.

Footnote:

A. (From Chapter 44, Airway Management in Adults, Miller’s Anesthesia, Ninth edition, pp 1373-1412)  “Topical application of local anesthetic to the airway should, in most cases, be the primary anesthetic for awake airway management. Lidocaine is the most commonly used local anesthetic for awake airway management because of its rapid onset, high therapeutic index, and availability in a wide variety of preparations and concentrations. Benzocaine and Cetacaine (a topical application spray containing benzocaine, tetracaine, and butamben; Cetylite Industries, Pennsauken, NJ) provide excellent topical anesthesia of the airway, but their use is limited by the risk of methemoglobinemia, which can occur with as little as 1 to 2 seconds of spraying. . . .  A mixture of lidocaine 3% and phenylephrine 0.25%, which can be made by combining lidocaine 4% and phenylephrine 1% in a 3:1 ratio, has similar anesthetic and vasoconstrictive properties as topical cocaine and can be used as a substitute. Topical application of local anesthetic should primarily be focused on the base of the tongue (pressure receptors here act as the afferent component of the gag reflex), the oropharynx, the hypopharynx, and the laryngeal structures; anesthesia of the oral cavity is unnecessary. . . . Before topical application of local anesthetic to the airway, administration of an anticholinergic agent should be considered to aid in the drying of secretions, which helps improve both the effectiveness of the topical local anesthetic and visualization during laryngoscopy. Glycopyrrolate is usually preferred because it has less vagolytic effects than atropine at doses that inhibit secretions and does not cross the blood-brain barrier. It should be administered as early as possible to maximize its effectiveness. “. . . Oropharyngeal anesthesia can be achieved by the direct application of local anesthetic or by the use of an atomizer or nebulizer. Topical application of local anesthetic to the larynx can be achieved by directed atomization of a local anesthetic or by the  spray-as-you-go (SAYGO) method, which involves intermittently injecting local anesthetic through the suction port or working channel of a flexible intubation scope (FIS) or optical stylet, as it is advanced toward the trachea.“Topical application of local anesthetic to the airway mucosa using one or more of these methods is often sufficient. If supplemental anesthesia is required, then a variety of nerve blocks may be used. Three of the most useful are the glossopharyngeal nerve block, superior laryngeal nerve block, and translaryngeal block. The glossopharyngeal nerve supplies sensory innervation to the posterior third of the tongue, vallecula, the anterior surface of the epiglottis, and the posterior and lateral walls of the pharynx, and is the afferent pathway of the gag reflex. To block this nerve, the tongue is displaced medially, forming a gutter (glossogingival groove). A 25-gauge spinal needle is inserted at the base of the anterior tonsillar pillar, just lateral to the base of the tongue, to a depth of 0.5 cm. After negative aspiration for blood or air, 2 mL of 2% lidocaine is injected. The process is then repeated on the contralateral side. The same procedure can be performed noninvasively with cotton-tipped swabs soaked in 4% lidocaine; the swabs are held in place for 5 minutes.”

ALCOHOL AND ANESTHESIA

THE ANESTHESIA CONSULTANT

You’re a patient scheduled for elective surgery tomorrow. You’re nervous and you’d like to drink a glass of wine (or two) at dinner the night before the surgery. Is this OK? What’s the relationship between alcohol and anesthesia?

Alcohol use is common in the United States—fourteen percent of the United States adult population suffers from alcohol addiction.  Surgery is common in the United States—there were more than 17 million surgeries performed in America in 2014. The intersection of an alcohol-addicted patient and surgery is therefore common. How much alcohol consumption is too much? The thresholds for defining high-risk alcohol consumption are 5 or more drinks in one day (>14 drinks per week on average) for males under 65 years of age, and 4 or more drinks in a day (>7 drinks per week on average) for all females and males 65 or more years of age. (Miller’s Anesthesia, 9th edition, Chapter 31, Preoperative Evaluation) All adults and adolescents should be questioned regarding their history of alcohol use prior to anesthesia. 

Let’s look at the risks for an acutely alcohol intoxicated patient first. Hospital emergency rooms have no shortage of drunken individuals who’ve been involved in motor vehicle trauma, motorcycle accidents, gang violence, or domestic violence. Acute intoxication with alcohol is usually diagnosed by history or by the smell of a patient’s breath. If an individual requires an acute surgical procedure, their level of intoxication is documented by measuring the alcohol concentration in their blood prior to surgery. Extreme levels of acute alcohol intoxication can cause coma or stupor, because alcohol is a central nervous system depressant, but other causes of decreased mental status must also be considered. An altered mental status in a trauma victim who smells of alcohol may be secondary to the central nervous system depressant effect of alcohol, or it may also be secondary to intracranial trauma. A CT scan of the head is indicated. High levels of alcohol intoxication alter a patient’s tolerance to anesthetic medications, because many anesthetics are central nervous system depressants just like alcohol, and there can be an additive effect between the alcohol and the anesthetic doses. Polydrug abuse is common, and blood tests are done on intoxicated patients to determine if other central nervous system depressants (opioids or sedatives), stimulants (cocaine, amphetamines), or other psychotropic substances (e.g. cannabis REF) are present. During surgery, anesthesiologists titrate medications to the desired effect by adding doses cautiously and following the effects on the patient’s vital signs of blood pressure and heart rate. Following surgery, anesthesiologists are vigilant symptoms of acute alcohol withdrawal syndromes. Chronic heavy alcohol use is associated with a two-fold to five-fold increase in postoperative complications, including higher rates of admission to intensive care units and increased lengths of hospital stay. (Chapman R, Plaat F, et al, Alcohol and Anaesthesia, Continuing Education in Anaesthesia, Critical Care and Pain, Volume 9, number 1, 2009, pp 10-13)

For elective scheduled surgeries, patients are seldom intoxicated, but the issue  of their chronic alcohol intake is important. Doctors and nurses question each patient regarding the history of alcohol consumption prior to surgery, and are aware that patients often downplay the quantity of their alcohol consumption. A patient who admits to one or two drinks per day may very well consume twice that amount. Chronic alcohol use can increase the dose requirements for general anesthetics, either because of induction/stimulation of the microsomal ethanol-oxidizing system (cytochrome P-450 system), or through the development of cross tolerance to other central nervous system drugs. (Chapman R, Plaat F, et al, Alcohol and Anaesthesia, Continuing Education in Anaesthesia, Critical Care and Pain, Volume 9, number 1, 2009, pp 10-13)

In contrast, chronic heavy alcohol use can cause cirrhosis and depress liver function. Certain anesthetic drugs, especially narcotics, are cleared by the liver, and decreased liver metabolism of narcotics can lead to relative overdoses. Chronic heavy alcohol use can also lead to cardiomyopathy with depressed ejection of blood from the heart, causing low blood pressures during and after anesthesia. Chronic alcohol dependence can cause central nervous system, gastrointestinal system,  hematological, metabolic, and musculoskeletal disorders. Because of the contrasting pharmacologic and physiologic effects of chronic alcohol dependence in a surgical patient, anesthesiologists will titrate the administration of  medications by monitoring the patient’s vital signs of blood pressure and heart rate, and adjusting the anesthetic depth required.

As a patient, what should you do? 

Be honest with yourself and your doctors if you drink daily. Alcohol dependence can and will affect your anesthetic and your body’s reaction to anesthetic drug dosing. Your anesthesiologist will be your consultant, and will administer anesthetic medications and doses in a range that is safe for you. In a perfect world, patients with heavy alcohol dependence should be identified before elective surgical procedures and referred to alcohol counseling services.

Does mild alcohol consumption of one to two glasses of wine or one to two beers per day increase anesthetic risk prior to surgery? Your risks will ultimately depend on the complexity of the surgery and the number of other medical problems that you have, but for most patients it’s unlikely you’ll have any anesthetic or surgical complication based only on this amount of alcohol consumption. One glass of wine with dinner may very well help you relax and get adequate sleep the night before your anesthetic.

A DAY IN THE LIFE OF AN ANESTHESIOLOGIST

THE ANESTHESIA CONSULTANT

One of my readers asked me to describe a day in the life of an anesthesiologist, as he was considering a career in anesthesiology. To aid you in visualizing yourself in the hospital, I’m substituting the pronoun “you” instead of “I” in the narrative below.

Your day is as follows, Doctor:

0530 hours – Your alarm goes off, awakening you and starting your morning. (Anesthesia is not the career for you if you like to sleep late—surgery always begins at 0730 hours). You complete your morning bathroom and breakfast routines, and leave your residence at 0630 hours for the hospital.

0645 hours—You arrive at the hospital, use your ID to open the gate to the parking lot, and walk one hundred yards from the parking lot to the hospital entrance. You take the elevator to the third floor and proceed to the locker room. The scrubs are enclosed in a device not dissimilar to a soda machine, and you need your ID to operate it. The machine opens and you extract a scrub top and scrub bottom in your size. You leave your street clothes in your locker. Because anesthesiologists do not scrub in a sterile fashion, it’s OK to wear your watch and ring., and to bring your cell phone with you.

Empty Operating Room

0655 hours—You don a bouffant hat and a facemask, and enter your operating room. Your hospital contains multiple operating rooms, and today you are in room #10. Your briefcase contains your personal medical equipment and office items you need for the day. Inside the operating room, the scrub tech is already dressed in a sterile gown and gloves, and is preparing the instruments the surgeon will use to operate on the first patient. The first surgery today is a procedure devised to treat obstructive sleep apnea, a procedure called a maxillary-mandibular osteotomy. An ear, nose, and throat (ENT) specialist will saw through the patient’s upper and lower facial bones, extend their bite forward to open the back of the throat further, and then fixate the bones in their new positions. The surgery will take approximately three hours. 

Your station in the operating room consists of an anesthesia machine; a bevy of vital signs monitors; a computerized pharmacy cart; a cart full of syringes and equipment; and the computer which handles the hospital’s electronic medical record (EMR).

Anesthesia Workstation

You log into the EMR system, and then you log into your first patient’s chart. You’ve looked over the patient’s information the night before, and you now review everything in detail, including the history, physical findings, vital signs, height, weight, body-mass index (BMI) from this morning, and any laboratory results.  

            Next you log into the patient’s file on the computerized pharmacy cart, and extract the controlled substances/drugs (Versed and fentanyl) that you will use for this case. The lower drawers to the computerized pharmacy cart unlock, and you’re able to access the propofol you’ll use to induce anesthesia. You fill a 20-milliliter syringe with 20 ml of propofol, and set it on the countertop. You remove a plastic breathing endotracheal tube (ETT) from its wrapper and set it next to the propofol syringe. You remove a lighted laryngoscope from a drawer and set it next to the ETT. You prepare several empty syringes which you’ll use to inject medications into your patient’s intravenous (IV) line.

Labelled anesthetic syringes

            Next you turn to the anesthesia machine and run through a checklist to assure it is connected to oxygen, full of the liquid form of the general anesthetic sevoflurane, and that all the hoses and valves are airtight and operational. You check the suction catheter system to document there is negative pressure should you need to suck saliva or vomitus out of the patient’s airway. You reach into your briefcase and pull out the stethoscope and peripheral nerve stimulator you’ll use during the case. 

Pre-Anesthesia Room

0700 hours—It’s time to meet your first patient. You walk into the pre-operative area, where your patient is wearing a hospital gown and is lying on a gurney. At this point every patient is apprehensive and anxious. You do your best to reassure him as you introduce yourself and sit down at the foot of the bed. Rather than launching immediately into medical questions, you begin by asking him what he would normally be doing on this day if he wasn’t at the hospital. This way you and the patient can connect on a human level before beginning the anesthetic proceedings. The patient will probably already have an IV in their arm, placed by a registered nurse. (To the contrary, in our practice we physician anesthesiologists start the IVs ourselves. We do this because we’re skilled at placing IVs painlessly and successfully, it doesn’t take that much time, and it gives the patient confidence that we’ll continue to take care of them at the highest level.)

            You ask the patient questions that are pertinent regarding their medical history. For example, if a patient has a history of asthma you’ll ask him if he has ever had an asthma attack severe enough to require treatment in an emergency room. If the patient was older than 50 years, you’ll ask him if he gets shortness of breath when he climbs two flights of stairs.

            Once your questions are answered, you’ll do a pertinent physical exam of the patient’s airway, heart, and lungs. Then you’ll explain the sequence of the anesthetic, as well as the anesthetic alternatives and risks. Your monologue goes as follows: “I’ll begin by giving you a medication in your IV which will make you feel less anxious. Then we’ll roll down the hallway into the operating room. There I’ll give you a medication which makes you lose consciousness. You’ll be asleep for the entire surgery. I’ll be with you that entire time, and you won’t feel any pain, or experience any awareness. During the time you’re asleep, there’s an airway tube in place. I’ll remove the tube when you wake up. You may have a sore throat from the tube. You may have nausea after general anesthesia. You’ll wake up reasonably comfortable, but as the general anesthesia wears off you’ll likely experience the onset of pain. There’ll be a nurse standing right next to you in the Recovery Room, and he or she will administer pain relieving medication to you if and when you need it. Do you have any questions?”

            After the patient gives verbal consent, you administer 2 ml of Versed (midazolam), a Valium-like benzodiazepine, into the IV. Within a minute or two, the patient feels the relaxing effect of the Versed, and you roll his gurney down the hallway toward the operating room.

Moving a patient from the gurney to the operating room table.

0715 hours—You roll the gurney in to the operating room. The patient moves himself from the gurney to the operating room table. You and the operating room nurse work to connect the patient to the standard vital signs monitors: the pulse oximeter on his fingertip, the three (or five) electrocardiogram stickers across his chest, and a blood pressure cuff on his arm. You turn to the EMR computer, and with a series of clicks you document the start of anesthesia time; begin data collection from the vital signs monitors; and identify which device (anesthesia machine/monitors in which operating room) you are connected to and receiving input from. You inject two prophylactic anti-nausea drugs, Zofran (ondansetron) and Decadron (dexamethasone) into the IV, and inject 2 ml (100 micrograms) of the narcotic fentanyl. You place an oxygen mask over the patient’s face so that the room air (21% oxygen and 78% nitrogen) that he has been breathing is replaced by 100% oxygen prior to going to sleep.

0725 hours—It’s time to begin anesthesia induction. You inject 40 mg of lidocaine, a local anesthetic, into the IV to blunt the burning sensation that propofol can cause. Then you inject 20 ml (200 mg) of propofol into the IV. Propofol is an opaque white liquid which disappears from the IV line as it enters the vein in the patient’s arm. Within 20 – 30 seconds the patient is unconscious. You ventilate the patient with oxygen for two breaths via the facemask to document that the airway is open and patent, and then you inject 4 ml (40 mg) of the paralyzing drug rocuronium into the IV. You continue to ventilate the patient via the facemask as the patient becomes paralyzed and unable to breathe for himself. You monitor the progression toward paralysis with a small battery-powered nerve stimulator device which you hold against the facial nerve area lateral to his eyebrow on the side of his face. 

Nasotracheal Endotracheal Tube

This surgery requires a specialized ETT which enters through the nose, courses through the back of the throat, and then passes between the vocal cords into the trachea (windpipe). You remove the facemask so the surgeon can insert cotton swaths soaked in local anesthetic into each nostril. Once all motor twitch activity is absent on the facial nerve monitor, you insert the nasal breathing tube, coated with a lubricating jelly, into the right nostril. You advance the tube through the nose until the tip appears in the oral cavity. At this point, you insert the lighted laryngoscope into the patient’s mouth, visualize the vocal cords, and push the ETT from outside the nose through the vocal cords into the trachea. You use a syringe to inflate air into the balloon cuff on the distal end of the ETT, and connect the proximal end of the ETT to the hoses on your anesthesia machine. You inflate the lungs via the breathing system, and listen with your stethoscope to document there are appropriate breath sounds in both the left and right lungs. You turn on your anesthetic vaporizer to administer a concentration of 1.5% sevoflurane gas to the patient. You tape the patients eyes closed so that they do not dry out under general anesthesia. Next you unlock the bed so that it can be rotated 180 degrees, so you are near the patient’s feet and the surgeon has the head of the bed to himself.

            While the surgeon, the nurse, and the scrub tech prepare the patient for the surgical incisions, you administer the antibiotic Kefzol (cephazolin) into the IV. Then you spend 10 minutes of time on the EMR, documenting every drug you injected and all the procedures you performed.

Maxillary surgery

0800 hours—Surgery begins. You titrate the depth of anesthetic drugs to match the degree of surgical stimulus. You do this by monitoring the blood pressure and heart rate, and use a variety of IV drugs to keep the vital signs from straying too high or too low from their pre-operative values. By 0830 hours you are finally able to sit down. The EMR inputs the vital signs automatically from the patient monitors into the medical record. You are vigilant regarding the surgical procedure, the IV infusing into the patient, the ventilator, and the inhaled and injectable anesthetics administered. At certain times during the case, when the surgeon is sawing into  the facial bones, he will ask you to lower the patient’s blood pressure in order to minimize bleeding from the bone. You do this by adding intravenous anti-hypertensive injections, and/or by deepening the level of general anesthetic drugs. As you near the end of this first case, you log into the second case of your anesthetic list on the EMR, and begin information gathering and EMR documentation as you did for your first case.

1130 hours—The surgery ends. You supervise the rotating of the operating room table 180 degrees, so the patient’s head and airway are adjacent to the anesthesia equipment again. You discontinue all anesthetic drugs and wait for the patient to regain consciousness. This can take from 5 to 15 minutes, and is a potentially hazardous time. Like landing an airplane, you need the patient to arrive at consciousness smoothly, without disruption in the vital signs. Most importantly you need him to be breathing safely through his newly remodeled face and airway.

1140 hours—The patient opens his eyes. You remove the ETT and place the oxygen facemask back over his nose and mouth. Once you’ve confirmed that he’s ventilating himself safely, you call for the gurney again. Together with the orderlies, the nurse, and the surgeon, you slide the patient back over to the gurney, and begin to transport him out of the operating room.

Post Anesthesia Care Unit

1145 hours—You push the gurney into the Post Anesthesia Care Unit (PACU), and into a parking berth staffed by a different registered nurse and another battery of vital signs monitors. You and the nurse connect the patient to the same monitors you used in the operating room, and document that the vital signs within safe limits. Then you give the nurse a verbal report of the patient’s preoperative medical problems and the pertinent surgical and anesthetic details. You proceed to the charting room, where you log into the EMR again and finish documenting all the data from the anesthetic. Throughout the time the patient is recovering in the PACU, the nurse follows medical orders you’ve written, and you’re responsible for the patient’s safety and well-being. The PACU nurse will call you for any questions or problems.

1155 hours—You find lunch somewhere. At my hospital there is no doctor’s cafeteria, and there is insufficient time to wait in line at the regular cafeteria. You may bring a sandwich from home, or you may subsist on protein bars, a bagel, a banana, or some yogurt you find in the operating room lounge. For anesthesiologists, the interval between surgeries is a time when the surgeons, nurses, and the empty operating room are waiting for you to get things going again. No surgery can proceed without anesthesia, so your between-case time is to be minimized. In some models of anesthesia care, a certified registered nurse anesthetist (CRNA) may break you out during the anesthetic or between cases, but when there is 100% physician anesthesia staffing, everyone is waiting for you between cases to get the next patient asleep.

1225 hours—You meet your second patient and go through the steps outlined beginning at 0700 hours above once again.

Depending on the length of your anesthetic list, you may be finished by 1400 hours (a 7-hour day), or you may be finished at 1700 hours (a 10-hour day), or if you are on-call you may work all night, until 0700 the next morning. The good news is that your pay is proportional to the duration of time and the number and complexity of the cases you do. When you are on overnight call as an anesthesiologist, you will usually have the next day entirely off.

Ambulatory Surgery Center

On certain days you may work at an outpatient ambulatory surgery center (ASC) instead of at a hospital. At an ASC the surgical procedures are simpler, and medical problems are screened beforehand so that no sick patients are allowed. Many ASCs have no EMR, and the charting is done by writing on paper with a ballpoint pen, which is less time-consuming than the current sluggish and expensive EMR systems used at hospitals. During an ASC day you may do one 8-hour anesthetic, or you may do eight 1-hour anesthetics. An ASC often provides food for their staff and their doctors, and you will be finished at a reasonable and predictable time, usually between noon and 1700 hours.

How are your emotions during your day as an anesthesiologist? It depends on how experienced you are. Even veteran anesthesiologists are on edge during the induction of anesthesia and the placement of breathing tubes. The maintenance phase of anesthesia, during the middle of the surgery, is predictably stable most of the time. Are you bored during this time period? Not likely, as there is enough going on with the surgical procedure, its effects on the patient’s physiology, and the pharmacology you are commanding. The end of each surgery increases the vigilance and anxiety level of the anesthesiologist once again until the patient is safely transferred to the PACU. Some cases are more stressful than others. Emergency surgeries, patients at the extremes of age (very young or very old), trauma surgeries, cardiac surgeries, lung surgeries, and neurosurgeries are among the most stressful. Anesthesiologists who practice these subspecialties are often adrenaline junkies themselves, and enjoy the challenge of more difficult cases.

After your work day you’ll drive home and enjoy a free evening. You typically won’t have any phone calls regarding the day’s patients. Once a patient leaves the PACU without complications, it’s unlikely there will be ongoing any issues for the anesthesiologist. For these reasons, anesthesiology is often considered a “quality lifestyle” medical specialty. I’d agree. Your evenings and weekends are usually free unless you are on call, which makes anesthesiology appealing. 

On each work evening you’ll receive your list for the following day’s cases. In our practice, we telephone each patient the night before to go over essential questions. Hopefully then you can go to sleep when you please. In my career I’ve had quite a few nights where the next day’s difficult cases gave me cause for concern or worry. Concerns and worries can lead to insomnia, a not-uncommon stressor for a practicing anesthesiologist. You might be worrying about a re-do heart valve replacement anesthetic on an 80-year-old woman, a throat surgery on a 340-pound man, or a list of 3-year-olds with obstructive sleep apnea who are having tonsillectomies. 

A career in anesthesia is not for the faint at heart. Mistakes or complications in our specialty can lead to bad outcomes in a matter of minutes. That said, a career in anesthesia is a fascinating and complex lifetime passion, during which you can help tens of thousands of patients undergo surgery safely.

THE ANESTHESIA CONSULTANT

The physician anesthesiologist job market looks excellent. Medical students, college pre-med students, and academically successful high school students, are you wondering if anesthesiology is a great career for you? The current demand for anesthesiologists is high. If you’re geographically mobile and willing to relocate to where the demand for anesthesiologists is maximal, you’ll have little problem securing a solid job.

Career Explorer reports, “There are currently an estimated 33,000 anesthesiologists in the United States. The anesthesiologist job market is expected to grow by 15.5% between 2016 and 2026.” Over the next 10 years, it is expected that America will need 6,200 anesthesiologists. That number is based on 5,100 additional anesthesiologists, and the retirement of 1,100 existing anesthesiologists.

Anesthesiology News reports a shortage in the anesthesia job market, which is fueling high job demand in the field.

The American Society of Anesthesiologists surveyed the job market in 2016. Their study reported: “At the time of the survey, almost all the (anesthesia resident) respondents had received job offers, with 97 percent having confirmed jobs. Among the geographic regions, percent of residents having a confirmed job ranged from a 93 percent (Midwest) to 100 percent (Northeast and West). Nationwide, a majority (55 percent) of residents were joining anesthesiology groups with plans to become a partner, while 45 percent accepted employed positions. The mean starting salary was $299,605 with a standard deviation of $77,000, reflecting considerable regional differences. Residents were asked to rank factors most important in choosing a job. The three most important factors included geography, job description and monetary compensation.” 

In just the past 7 days, I received the following unsolicited job offers via personal email. Seeing is believing, so peruse these requests for anesthesiologists and see what you think:

Here’s my advice:

Anesthesiology is a fascinating, challenging, adrenaline-charged career choice with a burgeoning job market. If you’re a student considering a career as a physician, The Anesthesia Consultant website strongly recommends a career as a physician anesthesiologist. For further information, I recommend the following columns from this blog:

THE TEN MOST SIGNIFICANT ADVANCES IN ANESTHESIOLOGY IN THE PAST DECADE

THE ANESTHESIA CONSULTANT

What were the ten most significant advances in anesthesiology in the past decade, 2010 – 2020? Here are my picks:

  • Sugammadex. Sugammadex was FDA-approved in December 2015, and the practice of chemically paralyzing surgical patients and reversing their paralysis has been forever changed. For my non-medical readers, sugammadex is an intravenous drug which reverses the paralysis of rocuronium, the most commonly used anesthetic paralytic drug, in approximately one minute. Sugammadex replaced the decades-old practice of injecting a combination of neostigmine and glycopyrrolate to reverse paralysis. Neostigmine and glycopyrrolate were slow to act (a wait of up to nine minutes), and could not reverse paralysis if zero twitches were present on a nerve stimulator monitor. In addition, 16 mg/kg of sugammadex IV can reverse an intubating dose of rocuronium, which makes rocuronium more quickly reversible than succinylcholine for rapid sequence intubation. Sugammadex is not cheap (a cost of $100 per 200 mg vial), but since the availability of sugammadex, no anesthesia practitioner should ever have an awake and still-paralyzed patient at the conclusion of an anesthetic. A terrific advance. Five stars.
  • Use of Zoom. In the era of COVID, Zoom videoconferencing made person-to-person communication involving anesthesiologists possible. During the early days of the COVID outbreak, the American Society of Anesthesiologists was able to keep its members informed and educated via Zoom conferencing. At the present time, almost all anesthesia continuing medical education (CME) is conducted effectively via Zoom. I attend the Stanford anesthesia Grand Rounds each Monday morning via Zoom, and the educational value is as high as it was when I attended in person. Expect Zoom CME to continue as a major vector in the years to come. Although Zoom may adversely affect in-person attendance at medical meetings forever, I believe widespread videoconferencing education is a tremendous advance. Five stars.
  • The Stanford Anesthesia Emergency Manual. See this link.  The algorithms set out in the red laminated ring-bound Stanford Anesthesia Emergency Manual filled a fundamental need in acute care medicine. When perioperative emergencies arise, a delay in treatment can result in death or irreversible brain damage. The presence of this Stanford book of checklists assures that every operating room is equipped with the cognitive aids needed for standard of care treatment. The manual is available at https://emergencymanual.stanford.edu. The authors chose not to glean profits from the publication of the Stanford Emergency Manual, but instead made it available for physicians and nurses everywhere for free. Five stars.
  • Safer care. Anesthesia care has become safer and safer. Deaths and adverse outcomes continue to decrease because of improved monitoring, vigilance, education, and training. The Cleveland Clinic writes, “In the 1960s and 1970s, it wasn’t uncommon to have a death related to anesthesia in every one of every 10,000 or 20,000 patients. Now it’s more like one in every 200,000 patients—it’s very rare.” The continuing advances in anesthesia safety are a bellwether for other specialties, who must envy the progress made in anesthesiology quality assurance. The Anesthesia Patient Safety Foundation is a hub of all advances. Five stars.
  • Pubmed/Internet/the Cloud. This past decade saw an explosion of handheld mobile devices and phones, as well as an expansion in the use of the cloud and the internet. Anesthesiology benefited from these technological advances. Information regarding anesthesia care is immediately available to any anesthesia provider anywhere in the world, if they have internet access. The ability to do a Google search on any topic is outstanding and immediate. Pubmed is a National Library of Medicine website which catalogs an abstract on every medical publication. Pubmed is an essential tool for every physician who is investigating previously published medical knowledge. Five stars.
  • Closed loop TIVA (total intravenous anesthesia).  Anesthesiologists and pharmacologists have been working on the pharmacokinetics of automated administration of intravenous anesthetics for years. Utilizing EEG monitoring data (BIS monitor levels) to titrate the depth of anesthesia shows promise. For a typical anesthetic, TIVA requires more work than vapor anesthesia with sevoflurane, because the anesthesiologist must load a syringe with propofol and/or remifentanil, attach an infusion line, load the syringe into the infusion pump, and program the pump to the correct infusion rate. In contrast, a sevoflurane vaporizer is already loaded with liquid anesthetic, is easy to use, and merely requires the pushing of one button and turning of one dial. Closed loop TIVA is not in clinical use at this time, but you can expect that the future, anesthesia recipes will include automated sedation/anesthetic depth titration via computer administration. The TIVA research of the past ten years has paved the way for this advance. Three stars.

The ultrasound-guided regional anesthesia boom. In the past ten years the number of ultrasound guided regional anesthesia blocks has mushroomed. Regional nerve blocks decrease the need for postoperative narcotics. Evidence shows that ultrasound guidance reduces the incidence of vascular injury, local anesthetic systemic toxicity, pneumothorax and phrenic nerve block for interscalene blocks, but there has not been consistent evidence that ultrasound guidance is associated with a reduced incidence of nerve injury. The ultrasound-guided regional anesthesia boom has led to tens of thousands of additional nerve blocks, and an unfortunate fact is that a small but non-zero number of these patients develop permanent nerve damage in their arms or legs after their blocks. Regional anesthesia specialists who publish in the medical literature have made little effort to quantify or report these complications. Prospective data on nerve injuries is needed. Honest verbal informed consent to each patient before a nerve block is needed. See this link. Three stars.

Point of care ultrasound (POCUS). In recent years, anesthesiologists began to aim their ultrasound probes at the abdomen, thorax, and airway, to gain real-time information and immediate knowledge of the anatomy and pathology beneath the skin and to better manage and treat critically ill patients. POCUS is proving useful in trauma , chest examination, and pediatric anesthesia. Because POCUS is a recent development, the majority of anesthesiologists do not have the training, skills, or knowledge needed to use this new technique. Recent graduates of residency and fellowship programs will lead the way as the anesthesia workforce transitions toward mastery of POCUS. Three stars.

  • ASA Monitor/Dr. Steven Shafer. I list this development last, but my enthusiasm for the ASA Monitor and its Editor-in-Chief Steven Shafer is extremely high. The American Society of Anesthesiologists revamped their ASA Monitor publication into a monthly newsletter reporting up-to-date information regarding our specialty. The ASA hired Steven Shafer MD PhD as the editor. Dr. Shafer is a Professor of Anesthesiology at Stanford, and is an outstanding scientist, author, and humorist. I’ve known Steve for nearly forty years, since he was a medical student. He has authored more than 200 peer-reviewed publications in the field of anesthesiology, and was the Editor-in-Chief for Anesthesia and Analgesia from 2006-2016. Dr. Shafer possesses a razor-sharp intellect and a flippant sense of humor seldom seen in scientific writing. His lead editorial in each month’s issue of the ASA Monitor is required reading for every anesthesia professional. Dr. Shafer also personally authors a daily update on COVID research and statistics—a Google group which you can personally subscribe to as an email offering. See this link. Five stars.

HOW DO PANDEMICS END? EXAMINING THE 1918 SPANISH FLU PANDEMIC

THE ANESTHESIA CONSULTANT

How do pandemics end? Now that COVID-19 vaccines have been approved, we’re all hoping this is the beginning of the end of this coronavirus pandemic. What about a history lesson—how did the last large respiratory viral pandemic end? The 1918 Spanish flu pandemic killed between 50 million and 100 million people, and was the third worst pandemic in the past 1000 years. (Number one was the bubonic plague/Black Death in the 1300s which killed 75 to 200 million people, up to 70% of Europe’s population.1 Number two is the HIV/AIDS pandemic which has killed 32 million people from 1981 to the present.2) How did the Spanish flu pandemic end? There was no vaccine technology in 1918. There were no intensive care units, there were no ventilators, and there wasn’t even a microscope powerful enough to see or identify the virus. There were no anti-viral drugs such as remdesivir or Regeneron’s monoclonal antibodies, and there were no antibiotics to treat the bacterial pneumonias that developed as complications of the flu. When people got a severe case of the Spanish flu, they died. 

H1N1 influenza virus

Novel coronavirus

The difference between the 1918 pandemic and the 2020 pandemic is the fact that the Spanish flu was an influenza virus, and COVID is caused by a novel coronavirus. Both are respiratory viruses, but influenza and coronavirus are two very different entities. Influenza is a seasonal infection which usually runs from autumn until spring. In a typical year, 200,000 Americans are hospitalized for flu-related complications. Over the past thirty years there have been between 3,000 to 49,000 influenza-related U.S. deaths every year. The 1918 Spanish flu pandemic was caused by an H1N1 influenza virus A. It lasted from 1918 to 1920, and infected 500 million people, more than one-third of the world’s population. REF https://www.cdc.gov/flu/pandemic-resources/1918-commemoration/1918-pandemic-history.htm  ). The pandemic killed between 50 million and 100 million people, including 675,000 in the United States. The pandemic occurred during World War I. The press in the United States and much of Europe censored early death tallies from the disease to minimize global panic. Spain was a neutral country in the war, and their newspapers were free to report on the disease, especially since their King Alfonso XIII  contracted the disease. Early stories from Spain created the impression that Spain was hard hit by the disease, and because of this the pandemic was named “Spanish flu.” 

The first wave of the Spanish flu began in the spring of 1918. The second wave began in August, and was more lethal than the first wave. In the United States the peak number of deaths were reported between September and December of 1918.  Infected individuals experienced typical flu symptoms such as sore throat, headache and fever. In January 1919 a third wave of the Spanish flu spread in Europe. The troop deployments and trench warfare of World War I facilitated disease transmission. Death was often caused by bacterial pneumonia  due to common upper respiratory-tract bacteria which invaded the lungs by infecting the viral-damaged airway cells.

Ninety-nine percent of Spanish flu deaths in the United States occurred in people younger than age 65, and fifty percent of the deaths were in young adults 20 to 40 years old. As in the COVID-19 pandemic, the entertainment and service industries suffered heavy economic losses. Public policy on curbing the spread of the Spanish flu was similar to the advice offered in the COVID pandemic: social distancing and masks-earing were encouraged. Frequent hand-washing, quarantining of patients, and closure of schools, public spaces and non-essential businesses were all utilized to minimize the spread of the disease.

How did the Spanish flu pandemic end? Individuals who were infected either died of influenza or survived and developed immunity. In the middle of 1920, the Spanish flu faded away enough on its own so that the pandemic ended.

Let’s compare this to the current novel coronavirus pandemic. As of this week there have been 300,000 COVID-19 deaths in the United States and 1.7 million deaths worldwide. So far less than 1 percent (74 million infected/7.8 billion total world population = .0095) of the world’s population is known to have been infected with the novel coronavirus. While the Spanish flu eventually faded away, as annual seasonal influenza usually fades away, the novel coronavirus has so far showed no signs of weakening. We are nowhere near herd immunity. Herd immunity is defined as “when a large portion of a community (the herd) becomes immune to a disease, making the spread of disease from person to person unlikely. As a result, the whole community becomes protected — not just those who are immune.”  

Doctors don’t expect the current COVID-19 pandemic to end until a significant percentage of the world’s population is vaccinated. According to Dr. Anthony Fauci, “Let’s say we get 75 percent, 80 percent of the population vaccinated. If we do that, if we do it efficiently enough over the second quarter of 2021, by the time we get to the end of the summer, i.e., the third quarter, we may actually have enough herd immunity protecting our society that . . . we can approach very much some degree of normality that is close to where we were before.”

Between twenty and forty percent of Americans say they will not take the COVID vaccine. This is a high number, and it strikes me as lunacy. The health consequences of you, your family members, or your friends developing a severe case of COVID-19 are well documented. Both the Pfizer and the Moderna vaccines showed minimal side effects in their clinical trials. Be smart. Get vaccinated as soon as you can. Herd immunity to the COVID-19 virus will only develop if we vaccinate the populace. Hopefully vaccine-induced immunity will curb the COVID-19 pandemic so the world can once again return to the lifestyles and freedoms we enjoyed in 2019.

THE ANESTHESIA CONSULTANT
Dr. Shirlee Xie, Minneapolis

This week Dr. Shirlee Xie, Associate Director of Hospital Medicine at Hennepin Healthcare in Minneapolis, Minnesota, taped an interview in which she described her personal experiences caring for COVID inpatients. I encourage you to watch the video on this link. Dr. Xie was highly emotional as she made the following remarks regarding COVID: (beginning at 2:53 of the video)

“I don’t think that people can really comprehend how horrific this disease is, unless they’ve been personally touched by it. I mean, people are literately suffocating inside our hospitals, and they are dying alone. And truly, my heart breaks for everybody who has lost their jobs or their housing, and for kids that aren’t able to go to school, and for people that aren’t able to see their families. And they don’t get the luxury to complain about COVID fatigue, and their families don’t get the luxury to complain about it, because they’re living in, like, COVID hell.”

I’d like to emphasize two words that Dr. Xie chose: suffocating and alone.

We’re all going to die someday. There are terrible ways to exit this life, and there are dignified, tranquil exits. 

As a physician, regarding end of life matters I prefer to see people die without pain and without suffering. Gasping for your next breath is a terrible way to exit this world. I place breathing tubes for a living, and I’ve seen patients gasping for their last breaths in emergency rooms, intensive care units, and other hospital settings. These patients are terrified and panicked. It’s an awful way to die. When I was in college and medical school I smoked Marlboros and enjoyed every puff. When I began my internal medicine residency I worked at the Palo Alto VA hospital, where I first saw veterans dying of emphysema and chronic obstructive pulmonary disease (COPD). Many World War II veterans smoked from the 1940s until the 1080s, and had destroyed their lungs. At their baselines they were unable to walk up one flight of stairs. When one of these patients acquired a respiratory viral infection, they would become acutely ill and need to be admitted to the hospital. These patients were gasping for breath and had to be supported in the ICU on ventilators. Being a patient on a ventilator is an ordeal. When you have a breathing tube in your windpipe, you can no longer talk. When you have a breathing tube in your windpipe, the stimulus of that plastic in your trachea is extreme (your reflex is to cough hard and reject the plastic tube from your airway). When you have a breathing tube in your windpipe, you need to be sedated so that you don’t panic, cough, buck, or pull the tube out of your body. After I’d seen a dozen formerly brave soldiers on ventilators, I quit smoking cigarettes for good. I hope never to die that way—sucking for my last breath.

In the intensive care unit, intubated and ventilated
In the intensive care unit, on a ventilator

When it’s time to die, most of us hope to die with someone we love near us at the bedside. I’ve stood witness to hospice deaths, where family members surround the bed as their loved one drifts off to sleep under the cloak of narcotic sedation and breaths their last. This is a calm, honorable death. No one wants to die alone, staring up at some white ceiling with an array of fluorescent lights as our last image of this world. No one wants to die alone, listening to ICU alarm bells chiming instead of the sound of our spouse’s voice or our children’s voices. Because of social distancing, family members and loved ones are not allowed inside hospital intensive care units during this time of COVID. When you’re dying of COVID, you’re alone, and you may never see the people you love ever again.

Hospice

Listen to what Doctor Xie says about COVID deaths. Suffocating alone. No one wants to die a premature COVID death. As doctors, we are well aware that the economic downturn of the COVID pandemic is affecting millions of people. An economic downturn such as this is awful. Hopefully Congress will seek to soften the hardship for those without jobs or housing. 

But when you’re dead, you’re dead. You don’t want “COVID hell.” You don’t want to die a COVID death. You don’t want your loved ones to die a COVID death. You don’t want your friends to die a COVID death. You don’t even want people you don’t like to die a COVID death.

Hang in there for a few more months. Do what the CDC and Dr. Fauci advocate: Socially distance, wear masks, and stay home as much as possible unless you’re exercising outside with social distance. 

Vaccines are on their way. This is just one year of our lives. Long lives, we hope. 

Without suffocating alone.

WHAT ANESTHESIOLOGISTS DO… AN EXAMPLE ANESTHETIC

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Most patients have no real idea what anesthesiologists do. Most college premed students have no real idea what anesthesiologists do. Most medical students have no real idea what anesthesiologists do.

Anesthesiologists are responsible for your medical care before, during, and after surgeries. At Stanford University we’re called the Department of Anesthesiology, Perioperative and Pain Medicine. “Perioperative” means “around the time of operations.” Today I’ll walk you through an example anesthetic which shows how an anesthesiologist approaches the challenges of a difficult surgical problem: emergency non-cardiac surgery in a patient with heart disease.

John Doe is a 58-year-old man with an acute inflammation of his gallbladder (acute cholecystitis), who needs to have his gallbladder removed (cholecystectomy). For the past 24 hours, Mr. Doe has suffered fever and acute right upper quadrant abdominal pain. His general surgeon advises surgery as soon as possible. Mr. Doe’s past medical history is positive for obesity (six feet tall, 240 pounds, BMI=32.5), coronary artery disease, and a history of stable angina.

PREOPERATIVE WORK: Anesthesiologist Dr. A reviews the chart and learns that Mr. Doe has had chest pain (angina) with exercise for the past two years. His cardiologist dida heart catheterization one year ago and discovered that Mr. Doe has small vessel coronary artery narrowing. His narrowed  vessels were too small to treat with coronary stents, and Mr. Doe received only medical therapy for his angina, in the form of isosorbide nitrate pills, diltiazem (calcium channel blocker pills), and nitroglycerin tablets as needed for chest pain. 

Mr. Doe takes a nitroglycerin tablet about once a week. This medical regimen has been effective in avoiding unstable angina and preventing heart attacks. Mr. Doe also takes atorvastatin (Lipitor) to control his hypercholesterolemia. Dr. A speaks with the cardiologist and asks two questions: “Are there any other diagnostic tests needed before surgery, and are there any other therapeutic measures needed before surgery?” The cardiologist answers that a preoperative echocardiogram is indicated, and he orders the test. The echocardiogram shows Mr. Doe’s heart is contracting normally (ejecting 60% of its volume with every beat). The cardiologist also measures the patient’s blood troponin level. Troponin levels are elevated when a patient is having an acute heart attack. Mr. Doe’s troponin levels are within normal limits, therefore no heart damage has occurred so far. Regarding therapeutic intervention, the cardiologist advises a continuous infusion of nitroglycerin to help prevent cardiac ischemia/heart attack damage during the anesthetic. 

An anesthesia machine, with the vital signs monitor screen on the left, and the electronic medical records computer screen on the right.

Dr. A meets Mr. Doe and interviews him. Mr. Doe is currently having moderately severe abdominal pain, nausea, fever, and chills. He has not had any chest pain for the past two weeks, and has no shortness of breath. His vital signs are heart rate = 100, BP = 150/80, respiratory rate =  20 breaths/minute, oxygen saturation 95% on room air, and temperature 100.2 degrees. Dr. A examines the patient and finds that the airway looks normal, the lungs are clear, the heart sounds are normal, and the abdomen is tender over the area of the gallbladder. Dr. A explains the general anesthetic plan to Mr. Doe, and informs the patient that his risk of heart complications for this acute surgery is higher than average because of the past cardiac history. Dr. A then records all pertinent preoperative information into the electronic medical record (EMR) via a computer keyboard and screen located just to the right of his anesthesia machine.

IN THE OPERATING ROOM: Mr. Doe will be asleep for the surgery, and Dr. A will be present the entire time. Mr. Doe has a preexisting intravenous (IV) line in his left arm. Prior to the surgery, Dr. A sedates the patient with 2 milligrams of IV midazolam (Versed) a benzodiazepine anxiety-reducing drug, and 100 micrograms of IV fentanyl, a narcotic.  

He then inserts a second catheter into the patient’s radial artery in its location at the right wrist. (I’ll use the male pronoun “he” for Dr. A in this example case, but be aware that as of 2017, 40% of anesthesiologists under the age of 36 years are female. This arterial line is connected to an electronic monitor which shows the blood pressure wave and blood pressure value continuously throughout the anesthetic. Dr. A places five ECG monitoring stickers on the patient’s chest, and a pulse oximeter on the third finger of the patient’s right hand. Dr. A notes the pre-anesthetic vital signs are heart rate = 80 beats/minute, blood pressure (BP) = 130/80, and oxygen saturation = 96% on room air, increasing to 100% on mask oxygen. This data is automatically entered into the chart of the electronic medical record.

MONITORING SCREEN with vs

After the patient breathes oxygen via a mask for two minutes, Dr. A performs a rapid sequence induction of anesthesia by injecting propofol (a hypnotic sleep drug) and succinylcholine (a muscle paralyzing drug) into the IV. The operating room nurse presses down on Mr. Doe’s cricoid cartilage in his neck, to compress the esophagus and prevent any stomach contents from regurgitating upward into the airway. 

Ten seconds after the propofol injection the patient is asleep. Forty seconds after the succinylcholine injection the patient is paralyzed. At this time Dr. A inserts a laryngoscope into the patient’s mouth and visualizes the patient’s vocal cords and the opening into the larynx or windpipe.

Under direct vision, Dr. A inserts a hollow plastic endotracheal tube (ET tube) into the patient’s windpipe, and then withdraws the laryngoscope. The cuff on the distal end of the ET tube is located just below the vocal cords, and Dr. A injects 3 milliliters of air into the cuff to inflate it and to secure the tube with a seal at the level of the windpipe. 

Dr. A then uses his anesthesia machine apparatus to squeeze breaths through the ET tube into the lungs, and listens to both sides of Mr. Doe’s chest with a stethoscope to document that breath sounds are present in both lungs. Dr. A glances at his anesthesia monitoring screen, which includes a row for the carbon dioxide detected in the exhaled breathing gas. The monitor screen traces a square wave vs. time, indicating that the ventilation of carbon dioxide (CO2) is now occurring out of the lungs with each ventilation. 

Dr. A secures the ET tube to the upper lip with adhesive tape, so the critical breathing tube cannot dislodge during the surgery. He sets the ventilator to deliver a volume of 800 milliliters into the lungs, nine times every minute. He sets the mixture of the inhaled gas as 50% oxygen and 50% air, with a resultant oxygen concentration of 60% oxygen. Dr. A turns on the sevoflurane vaporizer at this point, which releases a 1.5% concentration of sevoflurane vapor into the breathing mixture. 

Sevoflurane vaporizer (see yellow knob) on anesthesia machine

Sevoflurane, a potent inhaled general anesthetic drug, travels from the lungs via the blood stream to the patient’s brain, where sevoflurane molecules move from the bloodstream into the brain. This continuous delivery of sevoflurane molecules to the brain assures both sleep and amnesia. Dr. A injects an IV dose of 40 milligrams of rocuronium, a second paralyzing drug which will keep the patient motionless for approximately 30-40 minutes.

Dr. A prepares to start a central intravenous line into the right internal jugular vein. He preps the right side of the patient’s neck with Betadine iodine soap, and drapes the right neck with sterile towels. He places a probe on the patient’s neck from a device called an ultrasound machine. The ultrasound machine bounces soundwaves off the contents inside the neck, and generates a two-dimensional black and white image of the veins, arteries, muscles, and nerves found there. 

Dr. A inserts a needle into the right jugular vein under ultrasound visualization, and then inserts a wire through the needle into the lumen (center) of the vein. Seconds later, Dr. A slides a hollow intravenous catheter over the wire 14 centimeters into the center of the right internal jugular vein. 

Dr. A removes the wire and connects an intravenous drip to the central line catheter. He then connects a preprepared drip of nitroglycerin to a stopcock located on the central line IV, and turns on a preprogramed machine which infuses a small amount of nitroglycerin into the patient’s internal jugular vein continuously.

Dr. A steps back and surveys the patient’s vital signs. The BP is 100/50. The BP machine’s computer calculates a mean arterial blood pressure (MAP) as ((2 X diastolic BP) + systolic BP)/all divided by 3. The mean arterial pressure is thus ((2 X 100) + 50)/divided by 3 = 250/3, or 83. 

The desired range of the mean arterial pressure for this case will be from 65-90, and it will be Dr. A’s job to control the blood pressure within this range. The pulse rate is 60 beats per minute, and it will be Dr. A’s job is to keep the pulse rate from getting too high or too low (60 – 80 beats per minute is a desired goal). The oxygen saturation is 100%, and it will be Dr. A’s job is to keep the oxygen saturation, or O2sat, between 90-100%.

Dr. A administers an IV dose of an intravenous antibiotic prior to the surgical incision, and also administers two IV antinausea drugs, ondansetron (Zofran) and metoclopropamide (Reglan) prophylactically. He tapes the patient’s eyes shut so the corneas will not dry out and become scratched at any time during the surgery. 

Dr. A inserts an oral gastric tube through the mouth into the patient’s stomach, and suctions out any stomach contents. He inserts a temperature probe into the patient’s nose and connects it to a temperature monitor. He assists the nurses in positioning and padding the patient’s arms adjacent to the sides of his abdomen. He then wraps a plastic Bair Hugger blanket over the patient’s upper chest and head, and connects a Bair Hugger device which blows heated air through the bag to warm the patient if necessary during the anesthetic. 

The patient is now ready for the surgery to begin.

A nurse preps the abdomen by painting the skin with an antiseptic solution. The scrub technician and the surgeon drape sterile paper barriers over the perimeter of the abdomen, as well as a sterile paper vertical barrier (ether screen) between the anesthesiologist and the abdominal surgical site. 

The surgeon calls for a Time Out, at which time the operating room personnel review the patient’s name, the planned surgery, the patient’s allergies, and the estimated time for the surgery. Once the Time Out has been accepted, the surgeon begins the surgery. Almost all gallbladder excisions are done through a laparoscopic approach without opening the abdomen. The surgeon inserts a sharp trocar into the abdomen, removes the central core of this device, and then inflates carbon dioxide gas through the device into the interior of the abdomen. 

Once the interior of the abdomen is expanded like a balloon, an instrument with a camera on its tip is inserted into the abdomen, and the two-dimensional image of the interior of the abdomen is viewed on multiple video screens. The surgeon makes multiple small incisions and inserts additional surgical tools inside the abdomen.

The stimulus of the surgical incisions causes the blood pressure to increase. The mean arterial pressure (MAP) rises from 70 to 95. Dr. A deepens the anesthetic by injecting an additional two milliliters (100 micrograms) of IV fentanyl, which returns the MAP to 80 within two minutes. The insufflation of the abdomen with carbon dioxide is stimulating as well, because is stretches the lining of the abdomen (the peritoneum), and the MAP rises to 95 again. 

This time Dr. A increases the infusion rate of the nitroglycerin drip. Nitroglycerin dilates the venous blood vessels in the body which lowers the blood pressure, and also dilates the coronary arteries. He also begins a constant infusion of propofol via an intravenous pump to deepen the anesthetic level and lower the blood pressure further. The MAP decreases to 80 once again.

The surgeon requests the operating room table be tilted so the patient’s head is higher than the feet, and the right side of the patient’s body is higher than the left. Dr. A accomplishes this positioning by pushing buttons on the table controls. 

The purpose of this positioning is for gravity to move the intestines and abdominal contents downward toward the patient’s feet and toward the left side, thereby clearing the view of the gallbladder area in the right upper quadrant of the abdomen. 

There are hemodynamic (blood pressure and heart rate) consequences to this change in positioning. The MAP drops to 55 and the heart rate drops to 55. Dr. A treats the heart rate drop with an IV injection of atropine, an anticholinergic medication which blocks slow heart rates, and the pulse rate climbs back to 65. He chooses to treat the low MAP by injecting a small amount (5 milligrams) of a medication called ephedrine, which acts to increase both blood pressure and heart rate. The MAP returns to 70.

There is minimal bleeding during the gallbladder resection, and the experienced surgeon completes the surgery in 45 minutes. During this time Dr. A continues the maintenance anesthesia of sevoflurane and propofol, and injects further doses of the paralyzing drug rocuronium 20 milligrams (to keep the patient paralyzed ) and the narcotic fentanyl 100 micrograms (to provide ongoing pain relief).

As the surgeons close the final incisions, Dr. A removes the oral gastric tube and weans off the anesthesia drugs. The propofol infusion is discontinued. The sevoflurane is discontinued. The operating room table is returned to a level position. The rocuronium paralysis is reversed by the IV injection of a medication called sugammadex. As the anesthesia lightens, a predictable increase in blood pressure and pulse rate occurs, as the patient’s body begins to sense the stimulation of the breathing tube within the trachea and the sensation of the completed surgical repair. Once the patient is awake enough to breathe on his own, Dr. A removes the ET tube and places an oxygen mask over the patient’s nose and mouth. 

All critical care medicine is an effort to maintain Airway-Breathing-Circulation, in that order. Dr. A confirms that the patient’s airway is open in the absence of the ET tube, and that the patient is breathing adequately. 

Dr. A rechecks the vital signs and sees that the oxygen saturation is 98%, the pulse rate is 110, and the MAP is 110. The elevated pulse rate and blood pressure are dangerous in terms of this patient’s known coronary artery disease. The elevated high heart rate increases the cardiac oxygen consumption and lowers the time for the coronary arteries to fill between beats. The elevated blood pressure also increases the cardiac oxygen consumption, and puts the patient at a higher risk for heart damage or a heart attack. Dr. A treats both the elevated heart rate and blood pressure by injecting 10 milligrams of labetalol (an intravenous beta-blocker drug) which lowers the heart rate to 90 and lowers the MAP to 90 within two minutes. A second dose of IV labetalol brings the heart rate to 70 and the MAP to 80 within another two minutes. At this point Dr. A is satisfied that the patient is stable, and the staff prepares to transfer the patient to the post anesthesia care unit (PACU). A hospital bed is stationed to the side of the operating room table, and the monitors are disconnected from the patient. 

The orderlies, nurses, and doctors slide a roller device under the patient, and on the count of three they roll the patient onto the hospital bed. Dr. A secures an oxygen mask over the patient’s face, elevates the patient’s head to 30 degrees, and makes sure the IV line, the arterial line, and the internal jugular line tubings are all intact and not tangled for the transfer to the PACU. The baseline infusion of the nitroglycerin is continued throughout, as the cardiologist requested.

POSTANESTHESIA:  In the PACU, nurses reconnect the patient to the same monitoring devices worn during the anesthetic. A registered nurse personally attends to the patient in the PACU. The anesthesiologist writes all the orders for pain medications, cardiac medications, and anti-nausea medications.

The patient will stay in the PACU for approximately one hour, before he is transferred to the intensive care unit (ICU) for continued observation of his vital signs, cardiac condition, and for ongoing administration of the IV nitroglycerin. Once the patient is transferred to the ICU, Dr. A contacts both the ICU team and the cardiologist and signs off responsibility for the patient to them. In the ICU the cardiologist orders troponin levels once again, to determine whether or not the patient suffered a heart attack during surgery. The troponin levels are found to be low, indicating no heart damage occurred. The patient wakes up in a satisfactory status, with resolution of his abdominal pain. His vital signs remain normal.

Post Anesthesia Care Unit (PACU)

On the next day the patient’s nitroglycerin infusion is discontinued, his oxygen therapy is discontinued, and he’s discharged to a post-surgical ward bed. On the following day he’s discharged home.

This describes what an anesthesiologist does in performing a moderately difficult anesthetic. This model case is not unique to a university hospital—it could occur as described in any community hospital near you. Gallbladder surgery is not without risks, and not all gallbladder surgeries end well. In 5-10% of laparoscopic gallbladder surgeries, technical difficulties with the anatomy require the surgeon to switch to an open surgical method which requires a larger incision, and results in more postoperative pain. 

Open gallbladder surgery incision

As in any intraabdominal surgery, gallbladder surgery can lead to surgical complications such as:

  • Infection
  • Bleeding
  • Swelling
  • Bile leakage
  • Damage to the bile duct
  • Damage to the intestine, bowel, or blood vessels

Laparoscopic gallbladder surgery can lead to postoperative medical complications such as heart attacks, sepsis, pneumonia, pulmonary embolus (blood clot to the lungs), or rarely death. In 1987 pop icon Andy Warhol, age 58,  died just hours after gallbladder surgery in a prominent New York City hospital.  

No one ever disclosed what went wrong in Mr. Warhol’s case, but the anesthesia challenges for that surgery would have been similar to what was outlined above. 

This is what an anesthesiologist does. Your physician anesthesiologist is much more than a “sandman” or a “gas man.” Your physician anesthesiologist is your protector when you lose consciousness and go under the knife. While your surgeon attends to the surgical repair, your anesthesiologist will attend to your heart, brain, lungs, and the rest of your body . . .  before, during, and after your surgery.

Additional information on the profession of anesthesiology is available at the American Society of Anesthesiologists website.

THE TWO LAWS OF ANESTHESIA (ACCORDING TO SURGEONS)

THE ANESTHESIA CONSULTANT

There are Two Laws of Anesthesia, according to surgeon lore. They are:

  1. The patient must not move.
  2. The patient must wake up (when the surgery is over).

Surgeons work with physician anesthesiologists, with certified nurse anesthetists (CRNAs), or with an anesthesia care team that includes both physician anesthesiologists and CRNAs. Most surgeons’ comprehension of what anesthesiologists are doing is limited. Most surgery residencies have zero months of anesthesia training out of their sixty months of total residency. No matter who supplies the anesthesia services, to our surgical colleagues the critical requirements of anesthesia include 1. and 2. above. 

Period.

Physician anesthesiologists finish medical school and complete at a minimum four additional years of training. Surgeons finish medical school and complete at a minimum five additional years of training. There’s not much difference there. Anesthesiologists typically spend 90+% of their working hours in the operating room. A busy surgeon will spend 50% of their time in the operating room, and the other 50% in preoperative clinic, postoperative clinic, or rounding on patients in the hospital. Anesthesiologists win the tally for most operating room hours per week. Anesthesiologists take care of a patient’s heart, lungs, brain, and kidney function before, during, and after surgery. Surgeons perform a specific operation on one organ system, e.g. heart surgeons operate on the heart, orthopedic surgeons operate on a bone or a joint, and ear surgeons operate on ears.

Yet in all the surgical specialties, Two Laws describe the surgeons’ lofty expectations of anesthesia professionals:

  1. The patient must not move.
  2. The patient must wake up (when the surgery is over).

Physician anesthesiologists learn to perform anesthesia for all types of surgery, including cardiac, vascular, trauma, neurosurgery, pediatrics, eye, ear nose and throat, urology, and obstetrics. Physician anesthesiologists attend to patients of all ages, from newborns to centenarians. Physician anesthesiologists develop an extensive understanding of physiology as well as the pharmacology of hundreds of medications. Physician anesthesiologists regularly insert breathing tubes, venous catheters, arterial catheters, and stomach tubes, and inject regional anesthetic blocks into the spinal fluid, the epidural space, and learn nerve blocks of every major peripheral nerve.

Yet to our surgical colleagues, Two Laws describe an excellent anesthesiologist’s work:

  1. The patient must not move.
  2. The patient must wake up (when the surgery is over).

Let’s examine the Two Laws:

  1. The patient must not move. This Law is important because a surgeon must not be distracted by motion within the surgical field. If a patient coughs or bucks on the breathing tube, movement will occur. The surgeon must stop, sometimes for 60 seconds or more, while the anesthesiologist administers additional drugs to the patient. During these 60 seconds, it’s important that the surgeon sighs, crosses his or her arms, or otherwise expresses what a major inconvenience this loss of 60 seconds has been. Has a patient ever been harmed by an episode of brief movement? In the overwhelming majority of surgeries there is no harm whatsoever. In a perfect anesthesia world, patients will not move. But in the majority of anesthetics the patient is not chemically paralyzed, and it is possible for movement to occur. An overly deep level of anesthesia will help prevent movement, but has the adverse consequence of requiring a longer time to wake the patient at the end of the surgery. Which brings us to Law #2:
  2. The patient must wake up. When the surgeon finishes suturing the skin incision and  concludes the surgery, he or she will remove their gloves and gown and wait for the anesthesiologist to wake the patient. Modern anesthetics wear off quickly, and for most surgeries the duration of time from the end of surgery to the patient waking and talking is approximately 10 – 15 minutes. But these are minutes during which the surgeon must watch and wait. These are minutes during which the surgeon’s valuable time is ticking by, and seemingly wasted. In the overwhelming majority of surgeries, anesthesiologists successfully wake the patient and remove the breathing tube. At this time the surgeon can leave the operating room to meet with the patient’s family and discuss the successful operation. None of this could happen if the anesthesiologist was not competent with Law #2. 

If you’re a medical student considering a surgical specialty, it’s important you understand the Two Laws. If you become an anesthesiologist or a surgeon, you will be on one side or the other of the Two Laws. 

If you’re a patient, consider that it’s your surgeon’s job to cut and cure while it’s your anesthesiologist’s job to keep you from moving and to wake you up. Of course, your vigilant physician anesthesiologist will also assure that you’re safe, asleep, and unaware. Your vigilant physician anesthesiologist will also assure that you’re as stable and as healthy as possible after surgery. Trust your anesthesiologist  and realize that while these Two Laws come from the lips of surgeons, the genesis of the Two Laws perhaps occurred with a tongue in cheek. I’ve had excellent relationships with hundreds of surgeons over decades, and despite these Two Laws, the majority of surgeons are wonderful doctors and healers who are not condescending toward their anesthesia colleagues whatsoever.

TOXIC MARIJUANA SYNDROME YOU’VE NEVER HEARD OF: CANNABINOID HYPEREMESIS SYNDROME

THE ANESTHESIA CONSULTANT

Cannabinoid Hyperemesis Syndrome. Chances are you’ve never heard of it, but one of your patients, or someone you know, may develop this syndrome in the coming years. Cannabis use is common. According to The Washington Post, in 2017 more than half of American adults had tried marijuana at least once in their lives, and a total of 55 million Americans currently used the drug. This number approaches the total of 59 million cigarette smokers in America. Each year 2.6 million Americans become new cannabis users. The majority of marijuana users are male, earn under $50,000 a year, and lack a college degree. The 18–25 year old age group has the highest prevalence of marijuana use. 

Emesis is the medical word for vomiting. Hyperemesis means excessive vomiting. The number of people affected with Cannabinoid Hyperemesis Syndrome is estimated at about 2.7 million people in the United States per year. Cannabinoid Hyperemesis Syndrome (CHS) presents as a triad of chronic cannabis use, cyclic episodes of nausea and vomiting, and frequent hot bathing. If the patient withholds the history of chronic cannabis use, it’s difficult to impossible to make the correct diagnosis. Despite months of cyclical symptoms and thousands of dollars of Emergency Room visits and lab tests, the syndrome may not be correctly diagnosed or treated.

Let’s look at a case study of CHS to learn how it may present, and why it is uncommonly recognized:

A 25-year-old male presents for a diagnostic upper gastrointestinal endoscopy. He has a three-month history of persistent nausea, vomiting, and weight loss. His laboratory tests and CT scans of his abdomen and chest are normal. He carries a presumptive diagnosis of GERD (gastroesophageal reflux disease), and treatment with anti-acid drugs such as proton-pump inhibitors and H2-blockers have not improved the symptoms. The young man has been afraid to eat because of nausea and retching. He has been unable to work, and his sleep has been significantly impaired. He has lost weight from 150 pounds to his current weight of 135 pounds. On exam he appears well. His vital signs are normal, and his abdominal exam is negative for tenderness. He is scheduled for general anesthesia for the endoscopy procedure. He was referred for the upper GI endoscopy by his primary care doctor, and the gastroenterologist has yet to meet the patient.

Twenty minutes before his procedure, the anesthesiologist asks the patient if he takes any medicine or drugs. “Only the stomach pills my doctor prescribed,” he replies. “They aren’t working at all. I also use marijuana to decrease the nausea, but it’s not working either.”

“How frequently do you use marijuana?” the anesthesiologist asks. 

“Promise not to tell my parents?” he says. “I use a vape pen about 8 – 10 times a day.” 

“For how long have you been doing that?”

“About five years. I’ve increased my use over the past few months, because it’s supposed to be helpful for nausea, but it’s not working anymore.”

The anesthesiologist excuses himself, and sets off to find the gastroenterologist scheduled to do the procedure.  The anesthesiologist shares the cannabis history, and the gastroenterologist immediately says, “No one ever told me this patient was a chronic marijuana user. This changes everything. His history is classic for Cannabinoid Hyperemesis Syndrome.”

The gastroenterologist interviews the patient and confirms the correct clinical diagnosis. The treatment is immediate cessation of marijuana use, and the endoscopy is cancelled.

One week after stopping all cannabis use, the patient’s symptoms have completely resolved. He is eating well without nausea or vomiting, and has gained back 8 pounds.

Cannabinoid Hyperemesis Syndrome was first described in 2004 in a series of 9 patients from Australia.  In all of the cases, chronic cannabis abuse preceded the onset of a cyclical vomiting illness. Stopping cannabis led to cessation of the vomiting in seven cases. Three cases did not abstain and continued to have recurrent vomiting. Three other cases rechallenged themselves after a period of abstinence and relapsed to the same illness. Two of these cases abstained again, and remain well. The third case did not abstain, and remained ill. The majority of the patients displayed abnormal washing behavior during episodes of active nausea, in which they took repeated hot showers or baths, which temporarily relieved their symptoms.

Δ9-tetrahydrocannabinol (THC) is the principle psychoactive compound in cannabis. There are two distinct cannabinoid receptors, CB1 and CB2, in the human body, located predominately in the central nervous system and also in the gastrointestinal tract. THC stays in the body for a prolonged time, with an elimination plasma half-life of 20–30 hours. THC accumulates within body fat, and body fat serves as a long-term storage site. Typically THC can be used for its antiemetic (anti-nausea) property, and has been used to blunt nausea in cancer chemotherapy patients. With chronic use THC can induce a paradoxical nausea-inducing effect by unknown mechanisms on the central nervous system and the gastrointestinal system, causing the Cannabinoid Hyperemesis Syndrome. Patients with Cannabinoid Hyperemesis Syndrome are chronic users of cannabis who likely have large lipid reservoir stores of THC. 

CHS patients are typically young adults with a long history of marijuana use. There is usually a delay of several years following the onset of the chronic marijuana habit before the onset of symptoms. CHS patients often remain misdiagnosed. Erroneous diagnoses considered included a broad range of conditions affecting the gastrointestinal tract. In one study the average duration of cannabis use prior to onset of the recurrent vomiting was 19.0 ± 3.4 years, and had an average of 7.1 ± 4.3 emergency room visits, 5.0 ± 2.7 clinic visits, and 3.1 ± 1.9 admissions for the CHS syndrome. Daily marijuana use was typical, often exceeding 3 – 5 times per day. 

The three phases of CHS are prodromal, hyperemetic, and recovery. In the prodromal phase patients develop early morning nausea, a fear of vomiting, and abdominal pain. The hyperemetic phase includes episodes of intense and persistent nausea and vomiting. Patients vomit profusely, and can vomit or retch multiple times per hour. In the original 2004 Australian study, 70% of patients reported weight loss of at least 5 kg (11 pounds). Symptomatic patients typically undergo extensive diagnostic work ups, including laboratory and imaging studies, which are all normal or nondiagnostic. The recovery phase can last for days, weeks, or months. It occurs after the cessation of cannabis consumption, and is associated with return to normal eating patterns and original body weight.

The diagnosis of CHS must be made entirely by clinical history. The history of extensive previous cannabis use is universal, but may be unrealized if the patient withholds the information for personal reasons. A Mayo Clinic study in 2012 which included 98 patients, was the largest study to date. Characteristics of the Mayo CHS patients are shown in this table:

The Mayo series of 98 CHS patients helped establish these  diagnostic criteria. These criteria include: 

  • Essential for diagnosis: Long-term cannabis use. 
  • Major features: Severe cyclic nausea and vomiting, Resolution with cannabis cessation, relief of symptoms with hot showers or baths, abdominal pain epigastric or periumbilical, weekly use of marijuana. 
  • Supportive features: age less than 50 years, weight loss of > 11 pounds (5 kg), morning predominance of symptoms, normal bowel habits, negative laboratory, radiographic, and endoscopic tests.

Acute medical treatment for severe CHS episodes includes IV fluids for dehydration and supportive care. Traditional anti-emetic drugs such as Zofran have been largely ineffective. The only reliable long term treatment is the cessation of cannabis. The percentage of patients who relapse has not been quantified to date. The case series data in the medical literature currently document that many of the patients who return to cannabis use have recurrent CHS.

Voters have legalized the recreational use of cannabis in 11 states (California, Colorado, Washington, Oregon, Nevada, Maine, Alaska, Michigan, Illinois, Massachusetts, and Vermont). Because cannabis was legalized through popular vote and not via the usual Food and Drug Administration (FDA) channels, the drug did not undergo government scrutiny regarding toxicities and long term health effects. I discussed this topic in an earlier column.  

Cannabinoid Hyperemesis Syndrome should be considered as a plausible diagnosis in anyone with recurrent severe vomiting and a strong history of cannabis abuse. 

Because of recent legalization of recreational and medical cannabis use in many states, expect the incidence of Cannabinoid Hyperemesis Syndrome to increase. If your patient, or someone you know and love, develops recurrent severe vomiting in the setting of a strong history of cannabis abuse, the diagnosis may very well be Cannabinoid Hyperemesis Syndrome. 

The good news is that once the diagnosis is made, the syndrome is curable with cannabis abstinence.

COMPUTER SCIENCE VS. MEDICAL SCHOOL

Computer code
medical school

 

You’re a high school or college student with proficiency in science and math, and you’re wondering about your eventual career path. Two of the most ambitious career choices would be to go to medical school, or to go into some form of computer science/software/hardware engineering.

Which road is the correct road for you? 

It depends.

I’ve been a medical doctor for 40 years, practiced three different specialties, and worked on a top medical school faculty for 30 years. I understand the pathway of a medical career very well. I live and work in Silicon Valley. I have many friends and many patients who work in the tech/computer world, so I understand the life of a high tech career.

I have three sons, all of whom are skilled in science and math. I’ve discussed the pros and cons of being a physician with them since they were in elementary school, and they’ve observed my lifestyle. The career choices of my sons so far: one businessman, one computer scientist, and one 9th grader who is yet undecided (but leaning toward computer science).

Why are none of them pursuing medicine? They’ve listened to me and have made their own choices. What follows is the advice I give to young students skilled in science and mathematics who are trying to decide between medical school and a computer science career:

MEDICAL SCHOOL:

Positives:

  1. There is a high demand for MDs. You will have a job. As the Baby Boomer generation ages, they’re all requiring an increased level of health care intervention.
  2. You will be well paid. The average salary varies by specialty from $230,000/year for pediatrics to $480,000/year for orthopedic surgery.
  3. You’ll help people get healthy. That feels good. 
  4. Respect. Most people respect physicians.
  5. You can work into your 70s if you want to. There is minimal age discrimination.
  6. You’ll be a lifelong student. An emersion into medical knowledge makes you both an interested and interesting person your whole life. 

Negatives:

  1. Deferred gratification: it takes a long time to become an MD. You’ll be 30 years old at a minimum when you finish training. At that age you’ll have a negative net worth, and you’ll be financially years behind your friends who went to work immediately out of college
  2. You’ll work long hours, including sleeping overnight in hospitals during your training. 80-hour work weeks are common.
  3. You’ll acquire significant debt that will take you many years to repay. An October 2019 report from the Association of American Medical Colleges stated that 73% of medical students graduate with a mean debt of $201,490 and 18% with a mean debt exceeding $300,000.
  4. Medicine isn’t what it was in the 1960s-2000s, when MDs hung out their own shingle, thrived in private practice, and had significant autonomy. At the present time many young MDs are settling for a salary as an employee of a large organization. 
  5. Burnout is a constant risk. Electronic medical records require a significant portion of your work time, you may be required to see patients in 10-minute production-pressure clinic visits, and you’ll be on call during nights and weekends. Answering phone calls or being summoned into the hospital at 3 a.m. gets old.

 

 

COMPUTER SCIENCE/SOFTWARE/HARDWARE ENGINEER

Positives:

  1. You’ll be employable right out of college at age 22, with a good salary. The average income for a computer scientist is listed as $84,796, with a range from $69,000 – $114,000.
  2. High demand exists. You’ll get a job.
  3. You’ll have less educational debt, because you only went to four years of school after high school.
  4. Many students find computer science challenging and interesting.
  5. Computer science is changing the world we live in.
  6. It’s possible to work from home.

Negatives:

  1. Your salary will likely max out at less than an MD would earn. 
  2. It can be a lonely work life—just you and your computer. Computer science is rarely described as a social job.
  3. It’s possible your job will age-out in later years as you compete with younger, cheaper graduates with the same degree.
  4. You’ll probably have little autonomy. Most computer scientists work as a cog in some giant company. Think Google, Facebook, Apple, or Amazon.
  5. Competition exists. It’s difficult to be accepted into computer science programs at quality colleges—but it’s not as competitive as medical school acceptance. 

Listing the pros and cons of each career as I’ve done above will not make your decision for you. I recommend you make the decision between computer science and medical school with your gut, based on the following thought process:

Computer science and medical school are two appealing careers for students with strong science and mathematics backgrounds, BUT THE TWO JOBS ARE SO DIFFERENT. Medical doctors take care of people. We listen to patients, we hold their hands, we comfort them, and we attempt to heal them. Computer scientists work with code, chips, software, or hardware. The emotional milieu of these two careers could not be more different. 

Search your heart and you’ll know whether you’d rather spend decades working with people, or whether you’d rather spend decades working in a tech job. Search your heart and you’ll know whether you’d rather spend decades in an operating room/clinic setting, or whether you’d rather spend decades staring at a computer.

Then follow your heart based on those two images, and you’ll wind up where you need to be.

If you’re a real go-getter, you can complete undergraduate training in computer science and then go to medical school. Reference my column on How to Make a Billion Dollars in Healthcare to learn why a combined degree might be the educational pathway of choice for super-ambitious science and math students.

Good luck!

HILARIOUS GUFFAW-OUT-LOUD MEDICAL SATIRE BY TWO STANFORD PROFESSORS

THE ANESTHESIA CONSULTANT

Publish, Don’t Perish is a hilarious guffaw-out-loud medical satire written by two Stanford anesthesia professors, Dr. Jay Brodsky and Dr. John Brock-Utne. Not since The House of God have I read a book that spoofed the medical world in such accurate detail—absurd but almost believable.

The premise of the book relates to the truism than university medical faculty must “publish or perish.” Indeed the path of promotion to tenured professor status requires academic physicians to publish original clinical or laboratory research in reputable journals. Brodsky’s and Brock-Utnes’ book focuses on the new phenomenon of “predatory internet medical journals,” which will publish nearly anything if the author pays them a fee. 

An example email a doctor will receive from one of these predatory internet journals would be a poorly worded offer such as:  “Greetings. I hope you are well and trust you are doing splendidly. I’m Editorial Manager of The New American Journal of Medicine. We have seen your recent published articles and they seem to be very fascinating and it will be grateful if you accept to contribute a manuscript to our journal . We’ll accept anything. I really hope you won’t deny my mail and will surely submit a paper to the journal. We’ll publish it within two weeks.”

Publish, Don’t Perish presents fictional examples of medical studies that these new internet journals would be happy to publish. The parody examples from Publish, Don’t Perish include:

Study: Face Masks Can Alleviate Surgical Stress. Results:

Study: The Body Habitus of Miss America Contestants Have Shown an Ominous Decrease. “Since the iconic beauty pageant was established in the 1920s, the average BMI of the Miss America winner has now dropped to < 18 kg/m2. At the current rate of decline Miss America will have a BMI of Zero by the year 2300.”

Study: The Ideal PPE (Personal Protective Equipment) for the Operating Room. “To minimize exposure in the COVID-19 crisis, . . . we have provided all our physicians and nurses with atmospheric diving suits.” See below:

Letter: Orthopedic Surgeon Presents Alternative to Tracheostomy for ICU Patient. “An orthopedic surgeon was called to perform a tracheostomy in a COVID-19 patient with respiratory failure, . . . but the surgeon was unfamiliar with that procedure and decided to proceed with the only surgical airway management operation he was comfortable with.”

News: All Ancient Women Were Obese. “In a stunning announcement by several prominent anthropologists, the scientific and medical communities were shocked to hear of a new insight into human history. ‘We believe, rather than being the exception, that all Neolithic women were obese, and in most instances they were morbidly obese. . . . At excavations of sites twenty thousand years old, just a few examples of our finds are shown below.’”

The conclusion of this stunning announcement is, “Contrary to current teaching, it is obvious that the female body is meant to be obese.”

New Nursing Journal Announced. “The American Nurses Association is proud to announce the publication of our newest nursing journal, called ‘Anecdotes, not Science, Involving Nurses In New Environments,’ or ASININE.”

Case Report: Alexa Wakes Patient Up From Surgery. “When the surgeon told me he had ten minutes left in the case, I asked Alexa to set an alarm for thirty minutes because as you know, it always takes them about three times as long to finish.”

Other laugh-out-loud faux examples include:

Study Finds That Having Sex Without a Condom May Lead to Pregnancy.

Hospital News: Hospital CEO Accidentally Visits Operating Rooms: Finds Visit Productive

Case Report: Every Hospital Service Consulted on One Patient. 

120-Year-Old Doctor Called Out of Retirement to Fight COVID-19.  “As a young physician Dr. Tuttle sherperded Washington state through the devastating 1918 Spanish Flu influenza epidemic, and Dr. Fauci is listening to his recommendations.”

News: Anesthesia Blamed for Everything.

Nurse Earns Final Degree: Now Has the Entire Alphabet Behind His Name. “Richard R. Whitaker has recently completed his advanced degree in zoophobia, and thus became the first nurse to have every single letter of the alphabet listed behind his name.” example: Richard Whitaker, RN, PhD, CNP, CNM, ADP, AARP, . . . ZD.

Dr. John Brock-Utne and Dr. Jay Brodsky

Doctors Brodsky and Brock-Utne are distinguished experts in genuine medical writing. Between them they have published over 500 articles in the peer-reviewed medical literature. Publish, Don’t Perish, an 8 X 10- inch paperback, 80 pages long, is their first full-length book of satire. In a parallel universe both authors could have made a solid living as Saturday Night Live comedy writers, or perhaps they could have penned an R-rated comedy movie or two.

Five stars. This reviewer recommends you order a copy from Amazon right now. Make sure to order a gift copy or two for your orthopedic surgeon, hospital CEO, or favorite nurse as well.

PATIENTS: IS IT SAFE FOR YOU TO HAVE SURGERY DURING THE COVID PANDEMIC AS OF MAY 2020?

THE ANESTHESIA CONSULTANT

An important question for many Americans is, “Is it safe for me to have surgery during this COVID pandemic?”

It depends. 

In the San Francisco Bay Area where I work, the answer as of today, May 13th, 2020, is “yes.”

This is a key point: Healthcare professionals are more concerned with catching COVID-19 from you, the patient, than you should be concerned with catching COVID-19 within the healthcare facility. Read on to learn why.

The main questions as to whether a hospital or an ambulatory surgery center can resume elective surgery as of May 2020 are:

  1. What is the incidence of COVID-19 in your geographic area?
  2. Is testing for the virus that causes COVID-19 available in your area?
  3. Is there adequate personal protective equipment (PPE) at the facility?
  4. If you are having a major surgery in a hospital, will there be an adequate number of ICU and non-ICU beds, ventilators, medications, anesthetics and medical surgical supplies at the facility?

Your state health department will have statistics regarding the incidence of COVID-19 in your area. In Palo Alto, California, where I work at Stanford, the percentage of asymptomatic patients who have a positive COVID posterior nasal swab is quite low at 0.4%, or only 1 out of 250 people. The incidence of positive COVID antibody tests, indicating a prior exposure to the disease, is only 3%. Our county and state health administrations have noted a decline in the incidence of COVID cases, and have authorized a reopening of elective surgery. 

The American College of Surgeons, the American Society of Anesthesiologists, the American Association of periOperative Registered Nurses, and the American Hospital Association issued a joint statement on April 17th2020, stating that for reopening to occur, “there should be a sustained reduction in the rate of new COVID-19 cases in the relevant geographic area for at least 14 days and the facility shall have appropriate number of intensive care unit (ICU) and non-ICU beds.”

The joint statement also said that “facilities should use available testing to protect staff and patient safety whenever possible and should implement a policy addressing requirements and frequency for patient and staff testing.” Most facilities are interpreting this to mean that patients should have a negative COVID virus screening test prior to surgery. Most of these swab specimens are taken from the posterior aspect of the nose, although some tests only require an anterior nasal swab or a sputum/saliva sample. 

When you enter the healthcare facility, a nurse will question you regarding virus symptoms, and will screen you by taking your temperature. The inside of the healthcare facility will be cleaned prior to any patient care, and will be recleaned after each patient leaves an operating room. Everyone in the healthcare facility will be wearing masks. Everyone will be practicing social distancing of 6 feet unless they need to be closer to you to do their duty. All the precautions you’ve heard about multiple times from TV news reporters over the past weeks are strictly practiced inside healthcare facilities. When I’m at Stanford Hospital or the surgery centers in our area I’m confident the environment is safe.

Changes in the care of surgical patients during the time of COVID are best discussed in terms of preoperative care, intraoperative care, and postoperative care:

Preoperative care: No visitors are allowed into the perioperative region. At Stanford, if you have not had a COVID test prior to elective surgery, a nasal swab is taken on admission, and a rapid COVID test is done with the result available within about 2 hours. Healthcare workers take respiratory precautions with all patients as if that patient was COVID positive, whether the COVID test result has come back yet or not. You will wear a mask in the preoperative room, and that mask will remain on your face until just prior to the induction of anesthesia.

Intraoperative care: The American Society of Anesthesiologists states that “virus-carrying droplet particles become aerosolized into finer particles by airway procedures such as laryngoscopy, intubation, extubation, suctioning, and bronchoscopy, as well as by coughing and sneezing. These airway procedures and exposures carry a higher risk of infection for anesthesia professionals and other healthcare workers and require the use of rigorous PPE and environmental protection.” This means that when you are going to sleep or when you are waking up, airway procedures such as placing and removing a breathing tube are high-risk times for you to cough and project virus-carrying droplets into the atmosphere around you. The anesthesiologist wears full PPE (N95 mask, face shield, gown, two pair of gloves) during these times, and all other healthcare professionals (surgeons, nurses, techs) are to be at least 6 feet away or preferably outside of the operating room entirely. This is what your anesthesiologist will be wearing immediately prior to the time you go to sleep:

Postoperative care: When you awaken and your breathing tube is removed, the anesthesiologist once again places a paper surgical facemask over your mouth and nose to prevent you from coughing virus-containing droplets into the atmosphere of the operating room or the post-anesthesia care unit (PACU). If the procedure was an outpatient surgery, you will leave the facility and return home after you’ve recovered from anesthesia. Outpatient surgeries have the advantage of not requiring a hospital bed or an ICU bed/ventilator, which leaves these supplies available if a resurgence of COVID occurs in the community.

Which surgeries are commonly done as of May 13th, 2020? 

Each hospital or ambulatory surgery center is supposed to establish a prioritization policy committee consisting of surgery, anesthesia and nursing leadership, to develop a strategy to screen which surgical cases are appropriate to proceed with or not.

What do you, the patient, do with all this information? 

The timing of scheduling a surgery is always a balance of benefits and risks. Your surgeon will perform an essential surgery for you whenever a delay could cause harm. Your surgeon will weigh the risk of delay against the benefit that can be achieved by moving forward with your surgery. If your surgeon says your surgery is appropriate at this time, and you are willing to consent to the surgery, then you can move forward with the procedure. 

Healthcare professionals will adhere to the high quality standards as outline above, and surgery and anesthesia should be safe for you.

THE ANESTHESIA CONSULTANT

During this COVID crisis, intensive care unit and emergency room doctors and nurses in hotspots like New York City have dangerous, exhausting jobs keeping coronavirus patients alive. But the American medical response to the COVID crisis is bimodal. A minority of doctors and nurses are saddled with these dangerous around-the-clock jobs battling the disease in ICUs and ERs. The majority of doctors and nurses are on the sidelines, waiting for a return to work, just like many other workers in the United States. 

This has especially affected surgical teams. COVID-19 is a terrible medical tragedy, but it is not a surgical disease. In the United States as a whole, surgery has ground to a halt. Surgeons, anesthesiologists, certified nurse anesthetists, and operating room nurses are barely working at all now, for the fourth consecutive week.

The Center for Medicare and Medicaid Services (CMS) issued an edict on March 18, 2020 that all elective surgery be cancelled. The logic was sound and was twofold: 1) to keep doctors, nurses, masks, gowns, ventilators, ICU beds and hospitals unused for non-urgent care, therefore freeing up these assets to fight the coronavirus pandemic; and 2) to keep healthcare workers away from each other in a social distancing strategy to stop the spread of the virus.

The shelter-in-place orders that shuttered the economy have sidelined workers in multiple industries: the airlines, resorts, cruise ships, arenas, concerts, churches, retail, education, sports, etc. You can add elective medical care to this list.

According to CMS, what kind of surgery can be done during this pandemic? The CMS document says to “postpone non-essential surgeries and other procedures. This document provides recommendations to limit those medical services that could be deferred, such as non-emergent, elective treatment, and preventive medical services for patients of all ages.” 

Ambulatory surgery centers have been almost entirely shut down. The document “Additional Guidance on the ASC Community’s COVID-19 Response” reads:

Examples of cases that might still need to proceed with surgery at this time include:

  • Acute infection
  • Acute trauma that would significantly worsen without surgery
  • Potential malignancy
  • Uncontrollable pain that would otherwise require a hospital admission
  • A condition where prognosis would significantly worsen with a delay in treatment

Greater that 95% of the surgical cases for my anesthesia group have been cancelled for four weeks running. A Bay Area contingent of the California Society of Anesthesiologists held a Zoom conference last week, and the majority of attendees voiced that they were not seeing COVID duty, but their anesthetic workload had plummeted. 

Should these surgical specialists be moved into roles fighting COVID? In Northern California there has been no need. The existing ICU beds, ventilators, and ICU/ER staffing has largely been adequate for the number of COVID patients. Elective surgery has been cancelled at the hospital I work at, Stanford University Hospital, per the CMS edict. According to the Internal Medicine Grand Rounds lecture from April 8, 2020, Stanford Hospital currently had only 13 COVID patients, with 5 of those in the ICU on ventilators. The total overall number of COVID deaths at Stanford Hospital as of April 8, 2020 was 2 patients, and there were 54 unused ICU beds. 

The cessation of elective surgery is a source of economic hardship for many medical entities, including healthcare companies, hospital systems, surgeons, anesthesia professionals, and nurses. We’re all waiting for elective, non-urgent surgery to resume when it’s safe for the medical personnel and for the patients. Expect this to occur when widespread testing tells us that the medical personnel and the patients either test negative for the COVID virus or positive for the COVID antibody. Everybody is waiting on the tests. We don’t need thousands of tests, we need millions of tests in the United States.

Unemployed and underemployed Americans from multiple industries, including healthcare, hope this widespread testing will happen within weeks from this date, not months.

When you read the words “coronavirus and the sofa score” during a period of shelter-in-place for COVID-19, your first thought will be “laying on a sofa watching Netflix.”

Wrong. SOFA is a medical metric called the SOFA score.

This column is about rationing of ICU care and ventilators. If/when hospital intensive care units (ICUs) become overwhelmed with too many coronavirus patients requiring ventilators, then ethical choices may need to be made. If there are “n” number of ventilators and “n+10” patients who need one, who gets a ventilator and who does not? Which patients have an excellent prognosis to live and which do not?

Will ICU beds and ventilators need to be rationed in the COVID-19 crisis?

In crisis areas like New York City and Italy’s Lombardy region, anxiety and fear abound. I’ve previously posted this video showing the stress at an Italian COVID-19 ward.

This week I was contacted by a reader in his 70s who had a history of heart disease. His anxiety regarding the coronavirus epidemic was so high he asked me if he purchased a ventilator for the local university hospital, could he be guaranteed it would be available for him if he needed it? 

What data are available specifically for COVID-19 to address the question of which patients will have the highest ICU mortality?

Fei Zhou, MD et al published a retrospective study regarding COVID-19 patients from the Wuhan, China area in the medical journal Lancet. 191 patients were included in this study. 137 were discharged and 54 died in hospital.

Zhou measured data on each patient at the time of admission to the ICU. He discovered that the odds of dying in the hospital increased with: 

A) increasing age, 

B) a D-dimer level exceeding 1 mcg/L on admission, and 

C) a higher SOFA score on admission to the ICU.

Of these three criteria:

  1. We’ve already heard that a higher age is a risk factor for dying from COVID-19. See chart above
  2. A high D-dimer level indicates that increased blood clotting is occurring. The D-dimer is not specific, and can correlate with a deep venous thrombosis, a pulmonary embolus, or other diagnoses which include increased blood clotting. 
  3. What is a SOFA score? Read below:

SOFA stands for Sequential Organ Failure Assessment, and it quantifies the extent of a patient’s organ function or failure in six different organ systems: the lungs (respiratory), the heart (cardiac), the kidney (renal), the brain (neurological), the liver (hepatic), and the blood clotting system (coagulation). It’s used to predict ICU mortality based on lab results and clinical data. The higher the score, the worse the prognosis.

Let’s look at how each organ system is rated, first for a normal person like yourself, and secondly for a sick COVID-19 patient in the ICU:

RESPIRATORY:

Lung or respiratory failure is the most common failing system in sick COVID-19 patients. The SOFA respiratory score is based on the ratio of:  your blood oxygen level (PaO2) divided by the percentage of oxygen that you’re breathing. Right now your blood oxygen level is approximately 90 mm Hg, and the percentage of oxygen in room air that you are breathing is 21%, or 0.21 as a decimal. Divide 90/0.21 = 428. From the chart above, you earn 0 points, which is good. A COVID-19 patient sick with pneumonia may have a low blood oxygen level of 50 mm Hg on 100% oxygen, or 1.0 as a decimal (100% oxygen is the most a ventilator can deliver). 50/1.0 = 50, which earns that patient a respiratory score of +4 points.

CARDIAC:

The cardiac score is based on how high or low your blood pressure is, and on what concentration of adrenaline-like medication is required to keep your blood pressure up to a safe level. The blood pressure metric used is the mean arterial pressure (MAP), which is your average blood pressure. Right now your blood pressure may be 120/80, which equates to a mean arterial pressure of 93. Because you require no medications to keep your mean blood pressure > 70, you earn 0 points. A sick COVID-19 patient with heart failure might require a high concentration of an epinephrine (adrenaline) drip to maintain their blood pressure. This would earn them a cardiac score of +4.

RENAL:

The renal score is based on now much urine a patient produces per day, or how high their blood creatinine level rises to. Normal urine output is at least of 0.5 milliliters/kilogram of body weight per hour. A 70 kilogram (154-pound) human makes a minimum of 840 milliliters of urine/day, which earns them 0 renal points. A sick COVID-19 ICU patient with renal failure may make less that 200 milliliters of urine per day, which earns them a renal score of +4 points.

LIVER:

The liver score is based on how high the bilirubin concentration is in the blood. Bilirubin increases as a liver fails. Your bilirubin is a normal concentration of 1.0 mg/dL, and you earn 0 points. A sick ICU patient with a failing liver may have a buildup of bilirubin in the blood. An elevation to a concentration of > 204 mg/dL earns them a liver score of +4 points.

NEUROLOGICAL:

The Glasgow Coma Scale (GCS) quantifies the level of consciousness. Because you are awake and reading this, let’s assume you have a perfect GCS of 15. This earns you 0 points. A comatose patient on a ventilator may have a score of < 6, which earns them a neurological score of +4 points.

COAGULATION:

The normal concentration of platelets in the bloodstream is > 150,000, or (150 X 103 microL), and if you’re normal individual you will earn a score of 0. A sick COVID-19 patient in the ICU may be bleeding for a variety of reasons, and be consuming platelets trying to cease bleeding. A low platelet count of (20 X 103 microL) earns them a coagulation score of +4 points.

Zhou wrote: “Older age, elevated D-dimer levels, and high SOFA score could help clinicians to identify at an early stage those patients with COVID-19 who have poor prognosis.” 

What about rationing ICU care? Will older age or a higher SOFA score on admission impact a rationing of ICU care, that is, will older patients or patients with a very high SOFA score be denied a ventilator or an ICU stay? Will famous people or rich people score the last ventilators? I am doubtful this will happen in the ethical practice of medicine in the United States. But if the number of ICU patients greatly exceeds the number of ICU beds with ventilators, difficult choices may have to be made. Some patients may receive ventilators while others are denied ventilators. The Zhou data supports the premise that older patients and those with elevated organ failure scores on admission to the ICU have a worse prognosis. If ethical decisions are made, these two numbers (as well as an elevated D-dimer level) may be criteria which guide these difficult decisions.

Further research and data collection on COVID-19 patients in the hospitals and ICUs will give more detailed answers to these questions. Stay tuned.

I refer you to a fine and pertinent article written by Dr. Robert Truog, of the Harvard Center for Bioethics, entitled, “The Toughest Triage – Allocating Ventilators in a Pandemic,” published in the New England Journal of Medicine March 23, 2020.

The April 1, 2020 issue of The New York Times discusses the issue of rationing ICU care in New York City.

The Atlantic explores the issue of rationing of care in the era of COVID-19 in this March 28,2020 article.

CAN WEARING A FACE MASK SAVE YOUR LIFE?

THE ANESTHESIA CONSULTANT

During the COVID-19 pandemic we’ve been told not to wear a face mask if we don’t have viral symptoms.

Is this a mistake? Can a face mask save your life? I’m not talking about an N-95 mask, which blocks virus entry into your nose and mouth, and which are in short supply even for health care professionals during this pandemic, but a typical surgical mask, as pictured above.

Today I’m forwarding excellent information from a post by American viral specialist, James Robb MD, Fellow of the College of American Pathologists, a former Professor of Pathology at the University of California San Diego, and one of the first molecular virologists in the world to work on coronaviruses in the 1970s.

Dr. Robb is a proponent of individuals wearing surgical masks in public during a pandemic. He writes: 

“Stock up now with disposable surgical masks and use them to prevent you from touching your nose and/or mouth (We touch our nose/mouth 90X/day without knowing it!). This is the only way this virus can infect you – it is lung-specific. The mask will not prevent the virus in a direct sneeze from getting into your nose or mouth – it is only to keep you from touching your nose or mouth.

“The virus is on surfaces . . . This virus only has cell receptors for lung cells (it only infects your lungs). The only way for the virus to infect you is through your nose or mouth via your hands or an infected cough or sneeze onto or into your nose or mouth.”

This is a controversial recommendation. There are currently not enough surgical masks for everyone in the United States to be wearing one, but a face mask forms an effective blockade to an individual touching their own mouth and nose. The most common form of transmission of COVID-19 is likely autoinoculation of the virus from our hands to our nose, mouth, and eyes.

Dr. Jerome Adams, the Surgeon General of the United States, an anesthesiologist himself, and a professional I have tremendous respect for, tweeted this advice on February 29th, 2020:

“Seriously people- STOP BUYING MASKS! 
They are NOT effective in preventing general public from catching #Coronavirus, but if healthcare providers can’t get them to care for sick patients, it puts them and our communities at risk!”

It’s true that a typical surgical mask will not prevent you from inhaling the COVID-19 virus. And it’s also true that the medical teams in the United States need to have an adequate supply of surgical masks. But during this pandemic the facts are:  a) those doctors and nurses who are actually caring for or screening for coronavirus patients are wearing specialized N-95 masks, not regular surgical masks; and b) the need for surgical masks in the hospital has markedly declined because elective surgery in the United States is grinding to a halt during the current shutdown. Santa Clara County, where I practice in California, received a CDC recommendation that all elective and non-urgent surgical procedures be cancelled, and we are complying with this shutdown.

What if everyone in the United States started wearing a surgical mask all day? I’m not talking about an N-95 mask, which has twin elastic bands and forms a tight seal where the edges meet your skin. I’m talking about the looser version commonly worn in operating rooms. A tight N-95 mask is uncomfortable and will be often adjusted, necessitating multiple touching of the mask with your hands, which is could transmit the virus to the surface of the mask:

A looser fitting surgical mask is not uncomfortable, and is both a barrier to touch and a reminder not to touch one’s nose and mouth:

Is there any data that the barrier to touching their noses and mouths would slow the spread of COVID-19? No, there is no data, and there will not be anytime soon because no one has time to do such a study right now. But it’s common sense, as Dr. Robb recommends above, that preventing hand to face transmission is a vital part of curbing the spread of the virus.

On February 28th, 2020 a surgical colleague of mine who had just returned from Asia came to work and did surgery in one of our outpatient operating rooms here in California. One week later he was diagnosed with COVID-19 infection, and he was hospitalized. All the nurses, doctors, and techs who were present at work that day were placed on 14-day surveillance for the onset of COVID-19 symptoms, i.e. fever, cough, or shortness of breath. Sixteen days later, none of them have developed any symptoms of COVID-19. One of the reasons we attribute this positive outcome to is that all the doctors, nurses, and techs, as well as the infected surgeon, were wearing face masks. Almost no one will touch their nose and mouth if they are wearing a mask, and no one who is scrubbed in for surgery can touch their nose or mouth.

On March 12, 2020, in coverage of the COVID-19 pandemic, Time Magazine published an article Why Wearing a Face Mask is Encouraged in Asia, But Shunned in the U.S.” In Asia it became commonplace for individuals to wear face masks after the COVID-19 outbreak. They don’t have any data. They’re just worried.

We all should be worried at this point. If you cannot stop touching your mouth, nose, and face, and you can acquire a face mask, then consider wearing it. You don’t have to have a clean one each day. It’s not to prevent you from coughing on others, it’s to prevent you from touching your own face.

Is there any harm to wearing a face mask if you have one? I don’t think so. The benefit/risk ratio is high. Protect yourself and your family.

The question isn’t how many people in the United States will contract the coronavirus COVID-19. The key question is how many of these coronavirus cases will become extremely ill and wind up in an ICU. Authorities tell us two criteria define the threat of a virus: how quickly it can spread, and how severe or virulent the cases are.

How many of the infected patients will develop respiratory failure, and how many will require admission to an Intensive Care Unit (ICU) to be kept alive by a ventilator? To date there have been 90,000 coronavirus cases in the world and 3,000 have died, for a mortality rate of 3.33%. To date there have been 127 coronavirus cases in the United States and 9 have died, for a mortality rate of 7%. This statistic deserves an asterisk, because the denominator is likely too low. We don’t have data as to how many patients have contracted coronavirus, because testing has been limited to date.

We also have no information the numerator, the people who died. The Center for Disease Control (CDC) has released minimal information on the fatalities. For example, how many of the Kirkland, Washington deaths were elderly patients who were Do Not Resuscitate (DNR) status? That is, they were to be denied ICU treatment, ventilator support, and cardiopulmonary resuscitation (CPR) if they became seriously ill? How many of the deaths were vigorous adults who succumbed despite a full ICU effort to keep them alive?

What would the cause of these deaths be in a coronavirus-infected patient? The coronavirus is a respiratory virus which primarily infects respiratory tissues, much like the influenza virus does.  Symptoms could include sudden onset of fever, cough, headache, muscle pain, severe malaise (feeling unwell), sore throat, and a runny nose. With influenza illness may range from mild to severe and even death, but hospitalization and death occur mainly among high risk groups such as elderly patients or those with preexisting chronic illnesses.

A severe coronavirus infection would infect the lungs, and cause progressively increasing shortness of breath and dropping oxygen levels in a patient’s bloodstream. The medical treatment would be supportive, that is, a breathing tube would be placed in the patient’s windpipe (trachea) by an anesthesiologist, an ICU doctor, or an emergency room doctor, and the tube would be connected to a mechanical breathing machine, called a ventilator.

As of 2015, there were 94,837 ICU beds in the United States. Many or most of these beds are already filled by patients who need ICU support. If the new coronavirus were to become a pandemic which caused thousands or tens of thousands of cases of respiratory failure in the United States, each of these new coronavirus patients would require an ICU bed and a ventilator. This could quickly overrun our ICU capacity in America. 

That is the real scare of the coronavirus issue—the fear that our hospitals could not handle the volume of severe infections. Could temporary ICU beds be set up? Each bed would require a ventilator, a set of monitors, and around-the-clock nursing staffing. The supplies of each of these is finite. In addition, with an infectious disease such as coronavirus, each of these ICU beds would ideally be an isolation bed, which kept that patient quarantined from other patients and staff.

Can an anesthesia machine in an operating room be used as an ICU ventilator? Yes. Read more about that topic here. An operating room can be converted into an ICU room with the anesthesia machine ventilator keeping the patient alive.

In week one of the pandemic in California, I went grocery shopping at my local Safeway. The parking lot was full. When I arrived at the front door there were no shopping carts. Inside the store I saw hundreds of shoppers elbow to elbow in all the aisles. I asked an employee why the store was so busy, and she said, “This is nothing. You should have seen it yesterday—even busier!” “Why is it?” I asked. 

Her answer was two words: “The virus.”

She went on to say that customers were buying cleansing wipes, Advil, Tylenol, water, and food provisions that they could survive on for months. On my way out of the store, I saw my own primary care physician in the parking lot, and we discussed the shopping mayhem. He validated my views with the remarks, “It’s not if, but when, people will get infected. It’s just  too soon to know how many severe cases there will be.”

The Safeway customers buying Advil and Tylenol are worried. If you have a severe infection, Advil and Tylenol are not going to save you. What you would need is an intensive care bed with a ventilator, equipment to support your vital signs, and doctors and nurses to care for you 24 hours around the clock.

I hope and pray the overwhelming majority of coronavirus infections in the United States will be mild and self-limiting. A search for a vaccine and/or useful treatment drugs are underway. But because American medical systems need to be prepared, those in charge of health care administration are no doubt preparing contingency plans on how they can manage thousands of new patients in respiratory failure if needed.

ARE DOCTORS THE CULPRITS IN THE RISING COST OF HEALTHCARE?

THE ANESTHESIA CONSULTANT

Are doctors the culprits in the rising cost of healthcare? In a word, no. 

Does this story sound familiar? Your health insurance premiums are increasing by 12% each year. You or your employer pays this amount directly to Anthem, United Healthcare, or one of the other major health insurance companies. A drawback is  your health insurance policy comes with a $5000 deductible per person insured, so that you are paying out of pocket to get the first $5000 of each family member’s medical care each year. Because of this deductible cost, you choose to utilize as little health care as possible each year.

The result of this scenario? The insurance company wins in two ways:

1) The insurance company is collecting all time high premiums

2) You and the rest of the insured population are utilizing your insurance less, and choosing less health care visits and procedures because you have to pay cash for the initial expenses. 

Health insurance companies are primary culprits in the rising costs of healthcare.

I’m writing this from the viewpoint of a father who pays for the health insurance for a family of four. I currently pay $2000/month, or $24,000/year, for my group’s Anthem PPO (Preferred provider organization) coverage. My family’s in-network deductible is $5000/person, and our out-of-network deductible is $10,000/person. With this $5000 deductible per person, I may pay $20,000 in deductible payments before I gain any significant insurance coverage. If my family remains healthy, we are paying deductibles all year and gaining very little coverage for our insurance dollars. Our insurance is, in essence, catastrophic coverage in case we incur a major illness. 

I’m also writing this from the viewpoint of a working MD who sees declining payment and increasing difficulty contracting with these same healthcare organizations as a provider. 

The majority of health insurance companies are for-profit, and they are making record profits at this time. Forbes magazine reported that the health insurance industry “is enjoying a Golden Age of growth, sales and profits. ”

The top eight for-profit health insurance companies and their revenue for 2018, as reported by Forbes and Becker’s Hospital Review are listed below:

1. UnitedHealth Group
Membership: 49.5 million 
Revenue: $201 billion 

2. Anthem
Membership: 40.2 million
Revenue: $90 billion 

3. Aetna
Membership: 22.2 million 
Revenue: $60.6 billion

4. Cigna
Membership: 15.9 million
Revenue: $41.6 billion 

5. Humana
Membership: 14 million
Revenue: $53.7 billion

6. Centene
Membership: 12.2 million 
Revenue: $48.3 billion

7. Molina Healthcare
Membership: 4.4 million 
Revenue: $18.8 billion 

8. WellCare Health Plans 
Membership: 4.37 million
Revenue: $16.9 billion

The five largest health insurance or pharmacy benefit management (PBM) companies (Anthem, Cigna, CVS Health, Humana and UnitedHealth Group) in the United States collect revenues as large as the five dominant tech companies (Facebook, Amazon, Apple, Netflix and Google). 

Data: Company filings and FactSet; Chart: Naema Ahmed/Axios

  Data: Company filings and FactSet; Chart: Naema Ahmed/ 

These five health insurance/pharmacy companies had revenue of almost $787 billion in 2019, compared with $783 billion of projected revenue for the five largest tech companies. (Note: health insurers and pharmacy benefit managers pay much of their revenues to hospitals, doctors and drug companies, but these five companies are still recording billions in profit.) TheBest’s Market Segment Report stated that “through third-quarter 2018, health insurers’ net income grew by 19% to $25.8 billion compared with the same prior-year period.”

Los Angeles Times article said, “The truth is that private health insurers have contributed nothing of value to the American healthcare system. Instead, they have raised costs and created an entitled class of administrators and executives who are fighting for their livelihoods, using customers’ premium dollars to do so.”  The same article quoted Wendell Porter who said, “Health insurers have been successful at two things: making money and getting the American public to believe they’re essential.” 

The article went on to say, “The most perplexing aspect of our current debate over healthcare and health coverage is the notion that Americans love their health insurance companies. The increasingly prevalent mode of health coverage in the group and individual markets is the narrow network, which shrinks the roster of doctors and hospitals available to enrollees without heavy surcharges.  . . . Private insurers don’t do nearly as well as Medicare in holding down costs, in part because the more they pay hospitals and doctors, the more they can charge in premiums and the more money flows to their bottom lines. They haven’t shown notable skill in managing chronic diseases or bringing pro-consumer innovations to the table. . . . In reality, Americans don’t like their private health insurance so much as blindly tolerate it. That’s because the vast majority of Americans don’t have a complex interaction with the healthcare system in any given year, and most never will. As we’ve reported before, 1% of patients account for more than one-fifth of all medical spending and 10% account for two-thirds. Fifty percent of patients account for only 3% of all spending.”

(Image source: NIHCM)

Why do Americans want to keep their present healthcare insurers? Because the vast majority of Americans have very little need for medical care in any given year. That’s why most people are satisfied with their coverage. 

When will we see new models for private health insurance? The joint venture of Amazon, Berkshire Hathaway and JPMorgan Chase hired Harvard’s Atul Gawande MD, MPH as their CEO of their medical partnership. Many believe this organization will attempt to contract directly with major health systems, thereby bypassing traditional health insurance companies, in a quest to bring down costs. 

What can Congress do? What if they stipulate that health insurers pay out, for example, 97% of the premiums they collect? This concept, called a “medical loss ratio,” was part of the Affordable Care Act for plans sold on the federal health exchange to people under the age of 65. The Senior Citizens League webpage said, “The medical loss ratio sounds good in theory, but can contribute to rising healthcare costs due to ‘perverse incentives.’ . . If the insurance company has accurately built high costs into the premium, it can make more money.  Here’s how:  Let’s say administrative expenses eat up about 17 percent of each premium dollar and around 3 percent is profit.  Making a 3 percent profit is better if the company spends more.  It’s as if a mom told her son he could have 3 percent of a bowl of ice cream.  A clever child would say, ‘Make it a bigger bowl.’”

I’m not a socialist. I don’t support Medicare-for-all.  I’ve always believed capitalism and free enterprise would solve most economic problems. The current monopolies of health care insurance by a small number of for-profit health insurers is hardly a free market. There is inadequate competition against the Big 8 for-profit insurers, all of whom charge high premiums and bank massive profits. Health insurance companies are well represented in Washington D.C. Healthcare companies spent $3.9 billion dollars lobbying over the past 20 years.  

I encourage voters to pay careful attention to the issue of health insurance profits, and to pay careful attention to where presidential hopefuls and Congressional candidates stand on the issue. If politicians seem to be mouthpieces for the big business of health insurance industry, don’t vote for them. If they are advocates for change that help Americans gain affordable healthcare, I encourage you to vote for them.

As a physician, I’m particularly critical of the argument that doctors are causing the rising healthcare costs in American. The United States has the most expensive healthcare delivery system in the world, and it’s not because doctors make too much money. The administration of each healthcare dollar includes a syphoning off of huge profits by the insurance industry. A fine column by former President of the California Society of Anesthesiologists and UCLA professor Karen Sibert MD cites sources that physician are a mere 8% of America’s healthcare bill.  

Some journalists criticize physicians as an overpaid contingent who are inflating the cost of healthcare in America. Doctors are an essential profession in America. Physicians are suffering from high incidences of student debt, burnout, and premature retirement. As Karen Sibert MD wrote in another excellent column, “Keep up the insults, and good luck finding a physician in 10 years.”

Be informed and wary about the rising cost of health insurance and rising profits of the health insurance industry.

And I hope you stay healthy and don’t need to utilize your health insurance this year.

THE ANESTHESIA CONSULTANT

You use cannabis products. 

You’re about to have an anesthetic. 

Should you tell your anesthesiologist or not? Read on . . . 

PREVALENCE OF MARIJUANA USAGE

Cannabis, or marijuana, is used by approximately 2.7-4.9% of the world’s population, making it the most widely used illicit drug on Earth. Cannabis is also one of the most widely used drugs in the United States, where an estimated 22 million people over the age of 12 use cannabis products each year. 

SCHEDULE 1 DRUG 

Fifty years ago, in 1970, the Drug Enforcement Agency (DEA) regulated all cannabis products in the United States to Schedule 1 classification. Schedule 1 drugs have no accepted medical use and have a high potential for abuse. Other Schedule I drugs include heroin, LSD, mescaline, psilocybin, and ecstasy.  This classification of cannabis as a Schedule I drug made it impossible for American-based researchers to conduct research studies on cannabis products on humans. Typically a new medication must clear specific hurdles with the DEA before it is approved for public usage. At present the recreational use of marijuana is legal in 11 states: Alaska, California, Colorado, Illinois, Maine, Massachusetts, Michigan, Nevada, Oregon, Vermont and Washington, and also in Washington, D.C.

A problem exists because cannabis is categorized as an abuse drug that was not able to be studied, and has now been legalized without appropriate research. The physiology and pharmacology of cannabis in humans is also difficult to study because a) there are many different cannabinoids present in marijuana products, each with variable effects, and b) the drug can be either inhaled or ingested orally. If the DEA eventually removes cannabis from the DEA Schedule I list, then scientific prospective clinical trials can be done to better evaluate the implications of cannabis use.

WHAT WE DO KNOW

The most potent psychoactive product in the marijuana plant is delta-9-tetrahydrocannabinol, or THC.

THC is found in the flowering buds of the plant, and to a lesser degree in the leaves, stems, and seeds. The half-life of THC in the body is 5-13 days. Modern cultivation improvements have increased the THC content of cannabis. The average marijuana cigarette in the 1970s contained 1 – 3% THC, the average marijuana cigarette in the 1990s contained 6 – 20% THC, and some currently available strains have up to 33% THCButane hash oil extracts may have a THC concentrations as high as 90%.  The effects of cannabis are difficult to predict because the THC concentration in any delivered dose depends on both the THC concentration of the product, and the route of delivery.

CBD, short for cannabidiol, is a product marketed for antianxiety and chronic pain problems. CBD is not psychoactive, meaning it doesn’t have a strong effect on cognitive brain activity and doesn’t cause the central nervous system high associated with THC. Like all cannabis products, CBD is still classified as a Schedule 1 drug by the DEA. To date I’m unaware of any data that CBD interacts with anesthetics in any important way. 

ACUTE AND CHRONIC EFFECTS OF CANNABIS

To an anesthesiologist, a patient’s three most important physiologic systems are the brain, the heart, and the lungs. These are also the systems most effected by cannabis. Inhaled cannabinoids are rapidly distributed within the vessel-rich group of organs in the human body (the brain, lungs, heart, kidney, and liver), and effects are seen within seconds to minutes after an inhaled dose. The effects of orally ingested cannabinoids may be delayed up to 1 to 2 hours. 

CENTRAL NERVOUS SYSTEM/BRAIN

The most well known effects of marijuana involve the central nervous system, and include euphoria, sedation, and relaxation. Adverse side effects include apathy and lack of motivation.  Some users report reduced anxiety with cannabis use, but there are reports of worsened anxiety leading to paranoia or psychosis with cannabis use.There have also been case reports of acute psychosis after rapid ingestion of high doses of oral THC. Due to the central nervous system effects of cannabis, marijuana use has been implicated in motor vehicle accidents. Studies have shown a dose-dependent effect of acute cannabis administration on slowing the reaction time of drivers, and causing them to weave between traffic lanes. This is worsened by co-administration of marijuana with ethanol.These marijuana-plus-or-minus alcohol users may present to anesthesiologists for emergency surgical procedures related to traffic accidents. 

CARDIAC

The acute cardiac effects of cannabis administration include rapid heart rates (tachycardia) and the peripheral dilation of blood vessels, which causes low blood pressure.  A study showed that tobacco smokers with stable angina who never smoked cannabis developed angina with exercise significantly faster after smoking cannabis.  A second study showed a 5-fold increased risk of a heart attack (myocardial infarction or MI) in the first hour following cannabis smoking, compared to a 24-fold increased risk of MI in the hour following cocaine ingestion. The elevated risk of heart attack in cannabis users is thought to be due to a combination of the increased heart rate, the lower blood pressure, and the increase in cardiac work.  In the United States, cannabis use disorder has not been associated with any change in overall perioperative morbidity, mortality, length of hospital stay or costs, but cannabis use disorder is associated with an increased risk of postoperative myocardial infarction

LUNGS

Studies show bronchodilation and decreased airway resistance with either inhaled or ingested THC, but marijuana smoking can also result in airway hyperreactivity similar to that seen with tobacco smoking. Marijuana can be more irritating to airways because it burns at a higher temperature than tobacco. Cannabis is commonly smoked in hand-rolled and unfiltered cigarettes, or “joints,” introducing high concentrations of carcinogenic chemicals and irritants into the airways and lungs. Vaping cannabis oil promotes the inhalation of respiratory carcinogens and irritant compounds which can cause lung injury. Characteristics of cannabis smoking such as prolonged and deep inhalation, a shorter joint butt, and the higher combustion temperature, may result in greater carboxyhemoglobin  levels and tar retention in the airways. The chronic effects of inhaled marijuana include cough, bronchitis, and emphysema similar to those seen in chronic tobacco smokers.

WITHDRAWAL SYNDROME

The cannabis withdrawal syndrome is validated as a clinical entity in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as well as in the International Classification of Diseases (ICD) systems. Cannabis withdrawal syndrome can develop within a day after stopping high-dose chronic cannabis use. The symptoms include irritability, aggression, anxiety, insomnia, disturbed dreams, depressed mood, weight loss, abdominal cramping, sweating, fevers and chills.  

BEFORE SURGERY

In every cannabis using patient, the anesthesia preoperative evaluation should include assessment of the psychologic, cardiac, and pulmonary systems in order to minimize any risk of a perioperative complication. 

It’s important for the anesthesiologist to know the duration, frequency, and route of their patient’s cannabis use, as well as the time of most recent intake. Anesthesiologists should seek to identify patients as new or chronic cannabis users. If a patient exhibits any central nervous symptoms of acute cannabis intoxication, it’s important to assess the patient for symptoms of escalating anxiety, paranoia, or psychosis, as these symptoms may predict a violent emergence from anesthesia. The current lab testing methods assaying for plasma or urine cannabis levels do not provide effective quantitative data on cannabis intoxication. The history and physical examination by a physician are more important than a toxicology screen. Drug screening for cannabis is not currently a standard of care in preoperative medical evaluation.

Prior to urgent anesthetics on a patient with acute cannabis intoxication, the anesthesiologist will 1) consider delaying the induction of anesthetic induction until the resolution of tachycardia and/or low blood pressure, and 2) conduct a preoperative evaluation for chronic marijuana smokers similar to that used for chronic tobacco smokers. This includes questioning the patient regarding exercise tolerance, shortness of breath, chest pain, and listening to the lungs for evidence of chronic bronchitis or emphysema. 

ANESTHESIOLOGIST CONCERNS 

When attending to a cannabis user, the anesthesiologist must be aware that:  a) cannabis consumers may have an increased tolerance to anesthetics,  b) cannabis consumers have an unknown cross-tolerance to the anesthetic agents, c) cannabis consumers have an increased risk of myocardial infarction (MI or heart attack) within one hour after use, and d) cannabis consumers may have increased airway reactivity (i.e. wheezing, coughing, shortness of breath, or asthma symptoms).

In a prospective, randomized, single-blinded study, thirty male patients using cannabis more than once per week and 30 nonusers aged 18-50 years had anesthesia induced with propofol. The dose of propofol required for successful placement of a laryngeal mask airway (LMA) tube was significantly higher in the cannabis group than in nonusers

Researchers studied 27 patients undergoing elective orthopedic surgery who were randomly allocated to high dose cannabis (6 patients), low dose cannabis (8 patients), active placebo (6 patients) and placebo (7 patients). The cannabis drugs were administered 20 minutes before induction of general anesthesia in a double-blind fashion. During inhaled anesthesia, the researchers examined the patient’s bispectral index (BIS index, i.e. an intraoperative brain EEG level that measures depth of  general anesthesia). The average BIS values were significantly higher (i.e. the patients were not as deeply anesthetized) in the high dose cannabis treatment group. The researchers concluded that for cannabis consuming patients, one cannot rely on the EEG-BIS monitoring for the purpose of determining the patient’s anesthetic depth. An inference from this data is that cannabis patients were more tolerant of maintenance inhaled general anesthesia doses than non-cannabis users.

Because cannaboids are Schedule I drugs, and the effects of cannabis have been more thoroughly studied in animals. Studies in mice and rats showed cannabinoid-induced analgesic tolerance to morphine. There have been no similar studies in humans published to date. 

POSTOP:  INCREASED PAIN AND POSSIBLE WITHDRAWAL SYNDROME:

Following surgery, cannabis users report higher pain scores, worse sleep, and require more narcotics than non-cannabis users.  In Jamaica, a prospective randomized study was carried out on 73 patients who underwent elective surgery. There were 42 cannabis users and 31 non-users. The cannabis users required significantly higher supplemental Demerol (meperidine) doses after surgery.  (J Psychoactive Drugs. 2013 Jul-Aug;45(3):227-32)

As discussed previously, after surgery physicians should remain vigilant to cannabis withdrawal symptoms in chronic cannabis users.

AS THE PATIENT, WHAT SHOULD YOU DO?

If you are the patient, when you present for surgery and anesthesia, will the nurses and doctors specifically ask you if you use cannabis or marijuana? Perhaps not. Current routine preoperative evaluation usually includes the question “Do you use any street drugs?” Nearly 100% of patients answer “No.” As discussed above, 22 million people in the U.S. use cannabis, yet very few will admit this on a preoperative questionnaire. Why? I believe most people do not want to be identified as using a drug which is still deemed illegal by the federal government. Most people do not want “marijuana user” to be part of their medical history problem list. They may fear the moniker of “marijuana user” following them onto some digital database, damning them in future insurance applications or legal actions. I believe most people do not believe identifying themselves as cannabis users makes any difference to their doctors and nurses. Per the discussions above, there are important reasons for an anesthesiologist to know if you use cannabis. But if you are a cannabis user, will you reveal the truth?

Cannabis is currently legal and commonly used in multiple states in America. The drug has specific effects on the brain, heart, and lungs which can affect your health during or after an anesthetic. 

For your own welfare, be honest and discuss your cannabis use with your anesthesiologist prior to surgery.

ROBOT SURGERY . . . A VIEW FROM THE ANESTHESIOLOGY COCKPIT

THE ANESTHESIA CONSULTANT

Almost every anesthesiologist in America has experience with surgery using the da Vinci robot system. Is robot surgery a miraculous futuristic device that advances surgery to a higher plain? Or is it an expensive gadget for hospitals and surgeons to market and attract potential patients?

To answer these questions let’s first review some history. Until the 1990s most abdominal surgery was done through an open incision. To remove a gall bladder or an appendix, the surgeon made an incision into the abdomen, inserted his hands and instruments, cut out the tissue under direct vision, and then sewed the abdomen together again. A gall bladder incision might be five inches long. An appendix incision might be 2½ inches long. The surgical times were short—a private practice surgeon could complete an open gall bladder surgery in 30 – 40 minutes, or an open appendectomy in 20 – 25 minutes. A disadvantage was that the patient had pain from the incision, and the recovery time was days to weeks before the patient could return to normal activities.

Laparoscopy

Enter laparoscopy, a true major advance in surgery. The first video laparoscopic gall bladder resection (cholecystectomy)  was performed in 1987. A quantum advance occurred in the 1990s when video laparoscopic surgery became widespread. Laparoscopy required only small incisions in the abdomen, through which slender instruments were inserted. The interior of the abdomen was insufflated (blown up like a balloon) and one of the slender instruments held a camera. The image of the inside of the abdomen was visualized on a video screen while the surgeon manipulated instruments seen on that two-dimensional view. My colleague and Stanford clinical faculty member Camran Nezhat, the author of multiple textbooks on the topic, was a leading pioneer in the development of video laparoscopy. Laparoscopic surgery took longer than open surgery—a laparoscopic gall bladder or laparoscopic appendectomy usually lasted about twice as long as an open surgery—but the significant advantage was the lack of a painful open incision, which led to significantly less postoperative pain and a shorter postoperative recovery time. Many patients could be discharged the same day as their surgery, and most returned to normal activities sooner than if they had open surgery.  Video laparoscopy surgical equipment and the longer operating times were increased expenses, but the advantages of outpatient surgery and quicker recovery made the new technique the standard of care for many surgeries within the abdomen.

Anesthesia for laparoscopy was similar to the anesthetic for open abdominal surgery. Patients were asleep and paralyzed, and their breathing is done by a ventilator. The laparoscopy patient had a tense abdomen—it was essentially a balloon full of carbon dioxide—that usually required smaller volume breaths from the ventilator, but in most ways the two anesthetics were alike. 

da Vinci robot

Using the da Vinci robot for abdominal surgery is an extension of laparoscopic techniques, but the instruments are connected to robot arms rather than held by surgeons. The da Vinci surgeon sits at a console in the corner of the operating room, with his back to the patient and his face in a 3-D viewer, which gives a high-definition, magnified view of the surgical site. Assistant surgeon(s) and techs stand at the patient’s side, watch the surgery on video screens, and assist during the operation. The surgeon manipulates handles on the da Vinci device, which move the instruments within the patient’s body. The three-dimensional view within the abdomen is superior to a two-dimensional view on a video screen. I’ve personally had the opportunity to look through the 3-D viewer into the abdomen, and it’s a remarkable phenomenon. It’s as if you were a microscopic insect inside the patient, and looking around at the intestines, liver, arteries and veins that surround you. Another touted advantage of the robot is the ability for the surgeon to make precise movements via the robot’s mechanism.

The non-profit SRI (Stanford Research Institute) developed the early da Vinci system in the late 1980s with funding from the National Institutes of Health. The system was thought to have promise in allowing surgeons to operate remotely on surgeons wounded on battlefields. (When you read on you’ll realize how improbable this application would be.) 

In the 1990s, John Freund negotiated an option to acquire SRI’s intellectual property, and started a company named Intuitive Surgical Devices, Inc. The company’s prototype was ready for clinical testing in 1997. In 2000 the Federal Drug Administration (FDA) approved use of the da Vinci Surgical System for laparoscopic surgery, and Intuitive raised $46 million in an initial public offering. One year later the FDA approved use of the system for prostate surgery. In subsequent years the FDA approved the system for thoracoscopic surgery, cardiac procedures, and gynecologic procedures.

The da Vinci Surgical System spread slowly at first. Sixty hospitals in the United States used the system in 2002, but this number grew to 431 hospitals by 2014. Approximately 1,500 United States  hospitals now have the da Vinci Surgical System, according to Modern Healthcare. The system costs approximately $2 million, and there are costs for maintenance and for the non-reusable instruments held by the arms during surgery. A robotic surgery generally costs anywhere from $3,000 to $6,000 more than traditional laparoscopic surgery.  In 2016 Healthline wrote, “To justify its price — roughly 10 times that of a traditional laparoscopic surgery — da Vinci would need to do a lot better overall.” 

For abdominal surgery, use of the robot is as follows: The assembled robot is draped in sterile plastic and positioned distant to the patient, while the anesthesiologist induces general anesthesia and inserts an endotracheal breathing tube into the patient’s windpipe. The circulating nurse then preps the patient’s abdomen with antiseptic solution and the scrub tech surrounds the patient’s abdomen with sterile drapes. The surgeons insert a trocar to inflate the abdomen with carbon dioxide gas, and then make the incisions required for the insertion of the instruments into the patient’s body. When the robot is finally moved in over the patient and the instruments are connected to the robot arms, the anesthesiologist has limited access to the patient’s head, neck, and chest, due to the size, breadth and girth of the robot. The anesthesiologist’s station is within 4 – 6 feet of the patient’s head. At least one surgical assistant and one scrub tech stand at the patient’s side throughout the surgery. At a university teaching hospital, this number could be significantly greater. 

anesthesiologist (at right) during robotic surgery

The anesthetic for robotic abdominal surgery is no different than the technique for laparoscopy, except for one important feature. Robotic surgeries take longer than the same surgery done via traditional laparoscopy—a fact that makes most robotic procedures tedious for anesthesia personnel. Robot surgeries take up more of an operating room’s most precious resource—time. Hospital operating room resources—nurses, techs, orderlies, and administrative staff—are paid by the hour. Longer surgeries mean longer staffing hours and greater expense.

Do anesthesiologists prefer, enjoy, or feel challenged by these robotic surgery cases? In a word—no. There is little that is unique or challenging after one has done a few of these cases. In general anesthesiologists prefer surgery that is fast, efficient, safe, and effective.

1248 papers on “robot surgery” in 2019 to date

What does the world’s medical literature have to say about robotic surgery? When I entered the keywords “robot surgery, 2019” into the Pubmed search engine today, I discovered 1,248 papers published on robot surgery in the first 11 months of 2019. This is an exceptionally large number of publications. Robot surgery is a hot topic in the community of academic surgery. Multiple surgical specialties, including general, gynecology, cardiac, thoracic, cancer, and head and neck surgeons, are writing about their experiences with the da Vinci robot. You’ll find individual case reports, series of cases, meta-analyses, and comparison of current outcomes/complications to historical controls. 

Pertinent studies include the following:

Gall bladder surgery: In a 2019 study in the American Journal of Surgery, a national databank review of gall bladder resections (cholecystectomy) showed that the direct cost of robotic cholecystectomy was significantly higher than laparoscopic cholecystectomy, with no added benefit. The conclusion of the study was that “routine use of the robotic platform for cholecystectomy should be discouraged until costs are reduced.” 

Prostatectomy: A randomized controlled trial compared robotic surgery with open surgery for patients with localized prostate cancer, and showed that both robotic and open surgery achieved similar results in terms of key quality of life indicators at three months. 

Kidney surgery: A study published in the Journal of the American Medical Association (JAMA) showed the percentage of radical nephrectomies using the robot increased from 1.5% in 2003 to 27.0% in 2015. There were no significant differences between robot-assisted vs laparoscopic radical nephrectomy in major postoperative complications. The robot-assisted procedures had both longer operating times and higher direct hospital costs. 

Gynecology: The mortality in benign minimally invasive gynecologic surgery was low, and the mortality for laparoscopic vs robotic approaches was similar. 

Rectal surgery: JAMA publication showed that for patients with rectal carcinoma, robot-assisted laparoscopic surgery did not significantly reduce the risk of conversion to open laparotomy, when compared with conventional laparoscopic surgery. These findings suggested that robot-assisted laparoscopic surgery did not confer an advantage in rectal cancer resection. 

What will be the future direction of robotic surgery? Currently Intuitive Surgical and the da Vinci Surgical System have a monopoly. No other company has any significant market share. In 2017 Intuitive Surgical had $3.12 billion in total revenue, with a net income of $660 million. Their stock price is currently $549/share, up 300% from $178/share in January of 2016. The volume of robotic surgeries continues despite a paucity of published data that robotic surgery is any better. The cost of these procedures is high, and most hospitals are losing money on robot cases. Hospital executives seem to see the robot as a loss leader. No administrator wants to lead an old-fashioned hospital that doesn’t have a robot, while their competitor hospital across town is advertising robotic surgery on the side of buses traveling down Main Street.

Robotic surgery is a technology looking for a reason to exist, and a solution looking for a problem. Robotic surgery is not nearly the advance that laparoscopy was. Technology is pervasive and is changing healthcare. Enter any hospital today and you’ll see doctors and nurses peering into computer screens. They are pointing, clicking, entering information, and typing in findings on their patients. Where are the patients? Often they’re looking at the backs of these same doctors and nurses who are sitting at the computer terminals. Medicine, as I was taught in the 20th Century, was a profession dedicated to caring for and healing people. Modern medicine is increasingly pushing the hands of doctors and nurses toward keyboards and gadgets.

The surgeon with his face in a robot console’s 3-D viewer, while his back is to his patient, is a powerful metaphor for the technologic trend in medical care. I believe patients want to see our faces, and we need to look into their eyes. I doubt that great American physicians from our past—William Osler, Harvey Cushing, the Mayo Brothers, or Norm Shumway—would be fans of robotic surgery.

THE ANESTHESIA CONSULTANT
artificial_intelligence_ai_healthcare

My name is Rick Novak, and I’m a double-boarded anesthesiologist and internal medicine doctor and a writer of medical fiction. I’m here to talk about Doctor Vita, a vision of the future of Artificial Intelligence in Medicine.

I’m an Adjunct Clinical Professor of Anesthesiology, Perioperative and Pain Medicine at Stanford and the Deputy Chief of the department. I don’t tout myself as an expert in AI technology, but I am an expert in taking care of patients, which I’ve done in clinics, operating rooms, intensive care units, and emergency rooms at Stanford and in Silicon Valley for over 30 years.

AI is already prevalent in our daily life. Smartphones verbally direct us to our destination through mazes of highways and traffic. Self-driving cars are in advanced testing phases. The Amazon Echo brings us Alexa, an AI-powered personal assistant who follows verbal commands in our homes.Artificial intelligence in medicine (AIM) will grow in importance in the decades to come and will change anesthesia practice, surgical practice, perioperative medicine in clinics, and the interpretation of imaging. AI is already prevalent in our daily life. Smartphones verbally direct us to our destination through mazes of highways and traffic. Self-driving cars are in advanced testing phases. The Amazon Echo brings us Alexa, an AI-powered personal assistant who follows verbal commands in our homes. AIM advances are paralleling these inventions in three clinical arenas:

Surgical Robot

1. Operating rooms: Anesthesia robots fall into two groups: manual robots and pharmacological robots. Manual robots include the Kepler Intubation System intubating robot:

designed to utilized video laryngoscopy and a robotic arm to place an endotracheal tube, the use of the DaVinci surgical robot to perform regional anesthetic blockade, and the use of the Magellan robot to place peripheral nerve blocks.

Magellan robot for placing regional anesthetic blocks

Pharmacological robots include the McSleepy intravenous sedation machine, designed to administer propofol, narcotic, and muscle relaxant:

McSleepy anesthesia robot

and the iControl-RP machine, described in The Washington Post as a closed-loop system intravenous anesthetic delivery system which makes its own decisions regarding the IV administration of remifentanil and propofol. This device monitors the patient’s EEG level of consciousness via a BIS monitor device as well as traditional vital signs. One of the machine’s developers, Mark Ansermino MD stated, “We are convinced the machine can do better than human anesthesiologists.” The current example of surgical robot technology in the operating room is the DaVinci operating robot. This robot is not intended to have an independent existence, but rather enables the surgeon to see inside the body in three dimensions and to perform fine motor procedures at a higher level. The good news for procedural physicians is that it’s unlikely any AIM robot will be able to independently master manual skills such as complex airway management or surgical excision. No device on the horizon can be expected to replace anesthesiologists. Anesthetizing patients requires preoperative assessment of all medical problems from the history, physical examination, and laboratory evaluation; mask ventilation of an unconscious patient; placement of an airway tube; observation of all vital monitors during surgery; removal of the airway tube at the conclusion of most surgeries; and the diagnosis and treatment of any complication during or following the anesthetic.

IBM Watson AI Robot

2. Clinics: In a clinic setting a desired AIM application would be a computer to input information on a patient’s history, physical examination, and laboratory studies, and via deep learning establish a diagnosis with a high percentage of success. IBM’s Watson computer has been programmed with over 600,000 medical evidence reports, 1.5 million patient medical records, and two million pages of text from medical journals. Equipped with more information than any human physician could ever remember, Watson is projected to become a diagnostic machine superior to any doctor. AIM machines can input new patient information into a flowchart, also known as a branching tree. A flowchart will mimic the process a physician carries out when asking a patient a series of increasingly more specific questions. Once each diagnosis is established with a reasonable degree of medical certainty, an already-established algorithm for treatment of that diagnosis can be applied. Because anesthesiology involves preoperative clinic assessment and perioperative medicine, the role of AIM in clinics is relevant to our field.

Artificial Intelligence and X-ray Interpretation

3. Diagnosis of images: Applications of image analysis in medicine include machine learning for diagnosis in radiology, pathology, and dermatology. The evaluation of digital X-rays, MRIs, or CT scans requires the assessment of arrays of pixels. Future computer programs may be more accurate than human radiologists. The model for machine learning is similar to the process in which a human child learns–a child sees an animal and his parents tell him that animal is a dog. After repeated exposures the child learns what a dog looks like. Early on the child may be fooled into thinking that a wolf is a dog, but with increasing experience the child can discern with almost perfect accuracy what is or is not a dog. Deep learning is a radically different method of programming computers which requires a massive database entry, much like the array of dogs that a child sees in the example above, until a computer can learn the skill of pattern matching. An AIM computer which masters deep learning will probably not give yes or no answers, but rather a percentage likelihood of a diagnosis, i.e. a radiologic image has a greater than a 99% chance of being normal, or a skin lesion has a greater than 99% chance of being a malignant melanoma. In pathology, computerized digital diagnostic skills will be applied to microscopic diagnose. In dermatology, machine learning will be used to diagnosis skin cancers, based on large learned databases of digital photographs. Imaging advances will not directly affect anesthesiologists, but if you’re a physician who makes his or her living by interpreting digital images, you should have real concern about AIM taking your job in the future.

There’s currently a shortage of over seven million physicians, nurses and other health workers worldwide. Can AIM replace physicians? Contemplate the following . . . 

All medical knowledge is available on the Internet:

Most every medical diagnosis and treatment can be written as a decision tree algorithm:

Voice interaction software is excellent:

The physical exam is of less diagnostic importance than scans and lab tests which can be digitalized:

Computers are cheaper than the seven-year post-college education required to train a physician:

versus an inexpensive computer:

There is a need for cheaper, widespread healthcare, and the concept of an automated physician is no longer the domain of science fiction. Most sources project an AIM robot doctor will likely look like a tablet computer. For certain applications such as clinical diagnosis or new image retrieval, the AIM robot will have a camera, perhaps on a retractable arm so that the camera can approach various aspects of a patient’s anatomy as indicated. Individual patients will need to sign in to the computer software system via retinal scanners, fingerprint scanners, or face recognition programs, so that the computer can retrieve the individual patient’s EHR data from an Internet cloud. It’s possible individual patients will be issued a card, not unlike a debit or credit card, which includes a chip linking them to their EHR data.

What will be the economics of AI in medicine? Who will pay for it? America spends 17.8% of its Gross National Product on healthcare, and this number is projected to reach 20% by 2025. Entrepreneurs realize that healthcare is a multi-billion dollar industry, and the opportunity to earn those healthcare dollars is alluring.

It’s inevitable that AI will change current medical practice. Vita is the Latin word for “life.” I’ve coined the name “Doctor Vita” for the AI robot which will someday do many of the tasks currently managed by human physicians.

These machines will breathe new life into our present healthcare systems. In all likelihood these improvements will be more powerful and more wonderful than we could imagine. A bold prediction: AI will change medicine more than any development since the invention of anesthesia in 1849. Doctor Vita from All Things That Matter Press describes a fictional University of Silicon Valley Medical Center staffed by both AI doctors and human doctors. How physicians interact with these machines will be a leading question for our future. AI in medicine will arrive in decades to come. Michael Crichton wrote Jurassic Parkin 1990, 29 years ago, and we still do not see genetically recreated dinosaurs roaming the Earth. But we will see AI in medicine within 29 years. You can bet on it.

Here’s a dilemma: In 2018 and 2019 autopilots drove two Boeing 737 Max airplanes to crashes despite the best efforts of human pilots to correct their course. To date there have been 3 deaths of drivers in self-driving Tesla automobiles. What will happen when AI intersects with medicine and we have machines directing medical care? In the spirit of Jules Verne, this century’s trip around the world, to the center of the earth, to the moon, or beneath the ocean’s surface is the coming of Artificial Intelligence in Medicine.

What do the electric chair and anesthesiology have in common? The pertinent Venn diagram includes capital punishment, death by lethal injection, electrocution, and anesthesiology ethics. Anesthesiologists inject intravenous drugs to keep people alive during surgery. No anesthesiologist would be involved in lethal injection procedures or in recommending methods for killing another human being. Lethal injection requires someone to administer anesthetic medications in high concentrations without supporting breathing or cardiac function. On August 15, 2019 the state of Tennessee executed Steven West by electrocution for raping a 15-year-old girl and then killing both her and her mother in 1986. 

When given the option of lethal injection or the electric chair, West chose the chair. Uncertainties regarding current lethal injection drug regimens may have played a part in a recent inmate execution via the electric chair. Let’s look at the issues.

lethal injection table

Capital punishment by lethal injection is a relatively recent development. In 1982 Texas became the first state in the United States to use lethal injection to carry out capital punishment. The three intravenous drugs usually involved in lethal injection were (1) sodium thiopental, a barbiturate drug that induces sleep, (2) pancuronium, a drug that paralyzes all muscles, making movement and breathing impossible, and (3) potassium chloride, a drug that induces ventricular fibrillation of the heart, causing cardiac arrest.  

A barrier to lethal injection arose in January 2011 asHospira Corporation, the sole manufacturer of sodium thiopental, announced that they would stop manufacturing the drug. Hospira had planned to shift production of thiopental from the United States to Italy, but theEuropean Union also banned the export of thiopental for use in lethal injection.

Several death-row inmates have brought courtroom challenges claiming lethal injection violated the ban on “cruel and unusual punishment” found in the Eighth Amendment to the United States Constitution. There are drug regimen factors and technical factors regarding lethal injection problems. Regarding drug regimen factors, alternative sedative drugs such as midazolam, fentanyl, Valium, or hydromorphone have been considered to replace sodium thiopental, but there have been legal challenges as to whether inmates are indeed unconscious under these newer lethal injection recipes. The potential of cruel and unusual punishment can occur if the sedative combination does not reliably induce sleep, so that the individual to be executed is awake and aware when the paralyzing drug freezes all muscular activity. About ten years ago I was contacted by the Deputy Attorney General of a Southern state, who asked me if I would testify that a massive overdose of a single-drug intravenous anesthetic would reliably render an individual unconscious and anesthetized. The Deputy AG sent me the position paper authored by the opposition’s expert for the abolitionist argument. That paper was a massive treatise authored by an MD-PhD anesthesiologist-pharmacologist. The paper was approximately 80 pages long with hundreds of references. The abolitionist movement against capital punishment is strong. I declined to testify in support of the state’s lethal injection protocol. 

There are also technical factors involved with intravenous injection. A 100-fold overdose of a sedative should render an inmate asleep, correct? Not necessarily. What if the intravenous catheter or needle is incorrectly positioned, and the drug does not enter the vein in a reliable fashion? Is this a possibility? It is. If the catheter is not inserted by a trained medical professional it’s possible that the catheter will be outside of the vein, and the intended medications will spill into the soft tissues of the arm. The intended site of action of intravenous anesthetic drugs is the brain. To reach the brain the drug must be correctly delivered into a vein. Cases in which failure to establish or maintain intravenous access have led to executions lasting up to 90 minutes before the execution was complete. Thus the role of a medical professional to insert the intravenous catheter and administer the lethal injection is critical. The dilemma is that medical professionals are trained to save lives, not to execute people. The Hippocratic Oath clearly states that physicians must “do no harm” to their patients.

The American Medical Association states, “A physician, as a member of a profession dedicated to preserving life when there is hope of doing so, should not be a participant in a legally authorized execution.”

The American Society of Anesthesiologists states, “Although lethal injection mimics certain technical aspects of the practice of anesthesia, capital punishment in any form is not the practice of medicine . . . The American Society of Anesthesiologists continues to agree with the position of the American Medical Association on physician involvement in capital punishment. The American Society of Anesthesiologists strongly discourages participation by anesthesiologists in executions.”

The American Nurses Association states, “The American Nurses Association is strongly opposed to nurse participation in capital punishment. Participation in executions is viewed as contrary to the fundamental goals and ethical traditions of the profession.”

Without a trained medical professional to administer the intravenous catheter and inject the drugs in a reliable fashion, the practice of lethal injection has stalled in the State of California. Since 2006 there have been no death penalty executions by lethal injection in the state of California. In February 2006, U.S. District Court Judge Jeremy D. Fogel blocked the execution of a convicted murderer because of concerns that if the three-drug lethal injection combination was administered incorrectly it could lead to suffering for the condemned, and potential cruel and unusual punishment. This led to a moratorium of capital punishment in California, as the state was unable to obtain the services of a licensed medical professional to carry out an execution. There are currently over 700 inmates on death row in California.

Death by electrocution reentered the news this month. In the electrocution method, the condemned inmate is strapped to a wooden chair and high levels of electric current are passed through electrodes attached to the head and one leg. Lethal injection has been considered a more humane method of capital punishment than the electric chair. Tennessee provided inmates with a choice of the electric chair or lethal injection, and inmate Steven West chose the electric chair. Will electrocution replace lethal injection as the most common form of capital punishment in the United States? There is no current trend to support this. In 2018 there were 23 capital punishment executions by lethal injection, and only 2 by the electric chair. In 2019 there have been 10 capital punishment executions by lethal injection, and only one by electrocution.

Challenges to lethal injection are ongoing, and are in the domain of lawyers and courtrooms. If current lethal injection methods are ruled cruel and inhumane or if they are ruled unconstitutional, and states cling to the goal of capital punishment, we may see more headlines like this month’s electric chair execution from Tennessee.

DO DOCTORS EVER RIDE IN AMBULANCES?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

THE ANESTHESIA CONSULTANT

Do doctors ever ride in ambulances? Ambulances are a territory usually staffed by Emergency Medical Technician (EMT) personnel, but yes, in certain emergencies doctors do ride in ambulances.

In the process of doing 30,000 anesthetics, I’ve taken several rides in the back of an ambulance with my patients. Why? Sixty-six percent of surgeries in the United States take place as an outpatient, and many of these surgeries are performed at freestanding facilities distant from hospitals. When a patient decompensates emergently at a freestanding ambulatory surgery center or in an operating room at a doctor’s office, the facility will call for an ambulance staffed with EMT personnel. If the patient is unstable, a physician, usually an anesthesiologist, will need to accompany the patient and the EMTs to the hospital emergency room.

The following are examples of cases in which I or my colleagues have ridden in ambulances from freestanding surgery centers to the Stanford Emergency Room and Stanford Hospital in Palo Alto, California:

  1. A 3-year-old girl developed negative pressure pulmonary edema with plummeting pulse oximetry readings 10 minutes after a tonsillectomy. Her breathing tube had been removed, but she developed upper airway obstruction in the Post Anesthesia Care Unit (PACU) and needed urgent reintubation. She was extubated one hour later at the surgery center after treatment with diuretic, oxygen, and ventilation via the tube. She was then transferred to the hospital for overnight observation of her airway, pulmonary function, and oxygenation. The duty in the ambulance included monitoring her oxygenation, her airway and her breathing.  The presence of an anesthesiologist was reassuring to the stunned parents who had no expectation of a complication after a common surgery such as a tonsillectomy. The patient was discharged the following day without further complication.
  2. A 75-year-old female underwent lateral epicondylitis release surgery on her right elbow, and developed acute pulmonary edema with failing oxygen saturation levels at the conclusion of surgery. The patient had a past history of aortic stenosis, and had her aortic valve replaced with a small metal valve two years earlier. She was active, although she did experience mild shortness of breath on walking stairs. She was obese with a BMI=35. She received a general anesthetic with an endotracheal tube. The surgery was simple and the surgical duration was only 17 minutes. When the anesthetics were discontinued at the end of surgery, her blood pressure climbed to markedly high levels, and her heart failed to pump effectively against the elevated blood pressure. Pulmonary edema fluid filled her lungs and filled the hoses of the anesthesia machine. Her oxygenation returned to normal after titrating her BP down with a nitroprusside drip, and her blood pressure needed to be monitored continuously by an arterial line inserted into her radial artery at the wrist. The duty in the ambulance included ventilating the patient via the Ambu bag, keeping the patient sedated, watching the arterial line pressure continuously, and titrating the level of the vasodilating nitroprusside infusion. She remained intubated overnight in the hospital and was extubated the next day. She survived without any further complication and did not have a myocardial infarction. 
  3. A healthy 45-year-old woman developed acute hypotension 6 hours following a laparoscopic hysterectomy. The surgery was done in a small community hospital where there was no ICU, blood bank, or emergency room. The patient had multiple low-normal blood pressure readings over the first 5 hours postoperatively, and was being observed by the nursing staff. At hour 6 her blood pressure dropped to a dangerously low level and her hematocrit level on a portable device came back as 9.9%, indicative of a severe acute anemia. She was transferred urgently to the hospital. The duty in the ambulance included resuscitation with IV fluids, and observation of her airway and breathing as her level of consciousness dropped. She required repeat surgery at the hospital to control the intraabdominal bleeding, as well as preoperative transfusion to treat her anemia and hypovolemic shock.

These three cases are examples of surgical patients who became acutely ill miles from the nearest hospital. Each case illustrates how a failure of airway, breathing, or circulation can lead to an emergency. The problem in the first case was airway obstruction leading to pulmonary edema. The problem in the second case was lungs filled with fluid which made normal breathing impossible. The problem in the third case was bleeding which caused the normal circulation of blood within the body to be inadequate.

Why did an anesthesiologist travel with each patient? 

  1. Each patient was extremely sick and required acute monitoring and treatment, and medical decisions needed to be made during the trip to the hospital. EMTs are trained in resuscitation, but EMT training is only a fraction of anesthesiologist training. Having the anesthesiologist who was already resuscitating the patient continue to care for the patient en route to the hospital was the wisest course.
  2. Acute medical emergencies are defined by resuscitation of Airway-Breathing-Circulation. Anesthesiologists are the physicians with the highest level of airway skills, as well they are experts in acute resuscitation. If any physician is to travel with the patient, an anesthesiologist is the wisest choice to manage Airway-Breathing-Circulation in ongoing emergencies.
  3. Medical-legal risk is minimized if the most highly trained physician involved in the case continues to manage the case. The handoff or transfer of medical care from one practitioner to another is a high risk time for errors. The anesthesiologist  is responsible for the safety and care of his or her patient, and the highest continuity of care occurs when the anesthesiologist who managed the emergency attends to the patient during the transfer to the hospital.

I’ve been the Medical Director at a freestanding surgery center near Stanford for the past 17 years. Surgery centers strive to minimize the potential of emergencies in outpatient surgeries. Medical Directors work to limit the types of cases performed in a freestanding surgery center. This includes avoiding procedures that cause major pain, bleeding, or disruption of physiology. Typical surgeries performed in freestanding centers include:

  • Arthroscopic orthopedic surgeries
  • Simple ear nose and throat surgeries
  • GI endoscopies and colonoscopies
  • Simple general surgery procedures
  • Simple ophthalmologic surgeries
  • Plastic surgeries

Surgery centers also strive to operate on healthier patients who lack major comorbidities. Surgery centers are reluctant to approve general anesthesia in a freestanding outpatient setting to patients who have: 

  • Severe sleep apnea
  • Severe cardiac problems such as shortness of breath or ongoing chest pain
  • Severe morbid obesity or super-morbid obesity
  • Renal dialysis
  • Severe abnormal airways
  • Markedly abnormal blood pressures, heart rates, or blood oxygen levels

Regarding ambulance rides, no one is going to advocate that MDs take over EMTs roles regarding riding in ambulances. But when surgery or anesthesia leads to an acute event at a site distant from a hospital, the anesthesiologist involved in that patient’s care is responsible for that patient’s safety and for the ongoing care and resuscitation. The anesthesiologist will be riding in the ambulance and doing what anesthesiologists routinely do–managing Airway-Breathing-Circulation.

If any anesthesia professionals have stories regarding their own emergency ambulance rides resuscitating patients, I invite you to share them with my readers.

SURGICAL CASES IN FOREIGN LANDS—INTERPLAST

International Plastic Surgery

Imagine . . . rare unrepaired surgical cases in foreign lands, coupled with surgeons in America who rarely have the opportunity to operate on such cases. A win-win situation would be to fly American medical teams overseas to help these patients. This model for plastic and reconstructive surgery was born at Stanford University Medical Center in the 1960s in an organization named Interplast. During my anesthesia training at Stanford in the 1980s I was present through the growth years of Interplast, when traveling teams were dispatched to countries around the world to perform reconstructive surgeries on cleft lip and palate patients. Interplast was founded by Donald Laub MD, who was the Chief of the Division of Plastic and Reconstructive Surgery at Stanford from 1968-1980.

220px-DRLaub

Donald Laub MD

The idea for Interplast grew from the surgical history of Antonio Victoria, a 13-year-old with cleft lip and palate deformities that made him a social outcast in his home country of Mexico. Antonio arrived at Stanford University Medical Center in 1965. Dr. Robert Chase restored the boy’s appearance with three operations. Dr. Laub witnessed Antonio’s transformation and the idea for Interplast germinated.

In 1969 Dr. Laub founded Interplast (now called ReSurge International) with a mission statement to transform lives through the art of plastic and reconstructive surgery. Dr. Laub chronicles his history on his website Many People, Many Passports. Dr. Laub was the first academic to develop and lead multidisciplinary teams on humanitarian surgical trips to developing countries. The teams included plastic surgeons, anesthesiologists, pediatricians, and nurses experienced in the care of cleft palate reconstructions. The first trip to Mexicali was financed with a mere $500 of donations. Through contact with the governments and medical authorities in four countries, initial trips were scheduled to Mexico, Guatemala, Honduras, and Nicaragua. Seven hundred and fifty patients received treatment during the first five years, and an additional 150 were transported to Stanford for reconstructions in California. Through the 1970s and 1980s Interplast made trips to multiple other countries. The teams were made up of volunteers, and the trips were financed by charity donations.

Cleft lip deformity before and after reconstruction

Cleft lip and cleft palate deformities were common in Mexico and Central America, and the chances for surgical repair in the poor areas of these countries were minimal. Individuals with other deformities such as extensive burn scars were also social pariahs because of their appearance. Interplast made it a humanitarian goal to reconstruct these patients as well.

In addition to reconstructing patients, Interplast doctors educated local physicians in modern techniques. This was the medical equivalent of “give a man a fish and he eats for a day, but teach a man to fish and he will eat for a lifetime.” The opportunity to reconstruct patients with deforming diagnoses uncommon in the United States was life-changing for the American doctors as well. In the United States, the specialty of plastic surgery was seen as one concerned with enhancing the cosmetic appearance of cash-paying customers who desired a more youthful or beautiful appearance. In the third world, helping change a deformed child’s appearance was a unique emotional reward for American physicians who traveled there.

The administration of the Stanford University School of Medicine understood the value of the program. Stanford lent financial support to Interplast and financed Interplast rotations as part of the residency training programs in plastic surgery and anesthesiology. In our final year of anesthesia residency, each resident was assigned to a one week Interplast trip to perform anesthetics overseas. The week was not a vacation—we were paid during that week and the expenses of our airfare were covered by Interplast. Trip members typically lodged with members of the local community.

In 1986 I was assigned to San Pedro Sula, Honduras for my Interplast experience. Two weeks before we were to depart, our team assignment was changed to Montego Bay, Jamaica. I asked my faculty member if that was a positive change and he remarked, “You just traded the dusty streets of San Pedro for a Caribbean resort city. What do you think?”

Each Interplast anesthesia team included one faculty member and one or more resident. For my trip the anesthesia staff consisted only of myself and one Stanford attending—thus I received both an introduction to international pediatric anesthesia and one-on-one teaching from an experienced professor.

A striking difference between Interplast anesthesia and American anesthesia was the lack of sophisticated equipment overseas. Interplast members carried no narcotic medications across borders, for obvious political reasons. All postoperative pain was treated with local anesthesia injections from the surgeons (if local anesthetics were available), or by verbal reassurance from the nurses in the Post Anesthesia Recovery Unit (PACU). The PACU was often full of children screaming in pain after their palate surgeries. There are many nerve endings in the human palate, and after cleft palate reconstruction the pain is roughly equivalent to the pain of a tonsillectomy without any narcotic analgesia. It was difficult to listen to the children crying, but in time their pain would subside.

In the 1980s Interplast teams carried halothane, a potent liquid general anesthetic, as well as a halothane vaporizer to convert the drug into an inhaled gas. General anesthetics were initiated by holding a mask over a child’s face while they inhaled halothane vapor until they fell asleep. We started intravenous lines after the induction of anesthesia, but we had very few medications to inject into those IVs. Because there were dozens of cases to be done, the anesthesia attending and the anesthesia resident each did their cases alone and independently, in adjoining operating rooms. The rooms were primitive and usually had piped in oxygen, but lacked nitrous oxide availability.

Complications were rare, but their incidence was not zero. The combination of tiny patients, a paucity of medical drugs, a relatively inexperienced (i.e. not fully trained yet) anesthesia resident working alone, no ICU, no laboratory, and no emergency backup made every case an adventure. We had no complications on our trip, but there were a few anecdotes of cardiac or respiratory arrests from my colleagues who went to other countries.

As a partially-trained resident, I’d anesthetized less than 20 children in my life by the time of my Interplast trip. I was nervous during every anesthetic induction and every anesthetic wakeup. There were no American lawyers or malpractice suits to worry about in Montego Bay, but my job required me to accept responsibility for a child’s life. I’d take a child from his or her parents prior to the surgery and I didn’t want anything but a happy ending for that child, his parents, or me at the end of the day. We performed anesthetics from dawn until dusk. The lines of patients awaiting surgery were long, and each family clamored for the opportunity for their child to receive life-changing free surgeries from the American team.

Dr. Laub set the tone for Interplast. He made 159 trips and personally performed over 1500 operations overseas. He was and is a giving, confident, warm, and intellectual visionary. HIs office was decorated with a 1986 photograph of himself and President Reagan in Washington DC, marking the 1986 Private Sector Initiatives award Dr. Laub received for the creation of Interplast.In 2000 Dr. Laub was diagnosed with an aggressive intravascular central nervous system lymphoma. He survived the malignancy but retired from active clinical practice. I admire him for his surgical skills, entrepreneurial skills and positive attitude. No matter what difficulties arose in one’s life, Dr. Laub was ready to listen, quick to smile, and in closing he’d say, “May the wind always be at your back.”

Dr. Laub recently authored Second Lives, Second Chances: A Surgeon’s Stories of Transformation, a book describing his life, his founding of Interplast, and his pioneer work in trans-gender surgery. The link to the book can be found here.

I’ve continued to anesthetize children throughout my career. Anesthetizing toddlers by yourself is not like riding a bike. Once you learn to do it, the skills must be retained with frequent repetition or else you run the risk of being unsafe. The majority of anesthesiologists cease anesthetizing children soon after residency, and choose not to build on the pediatric anesthesia skills they learned as trainees. I feel fortunate that my practice still includes anesthetizing children every week. In part I owe this to Interplast for introducing me to my early pediatric anesthesia experiences.

A medical career requires years of memorizing facts as well as tireless nights and days attending to sick patients to learn the art and science of healing. Interplast taught more—the doctors and nurses who journeyed to foreign lands to improve the lives of poor children reaped the emotional benefits of being a medical professional. Nothing in our job feels better than helping a sick child become healthier or helping a family gain a new lease on that child’s future.

Interplast has now become Resurge International (REF https://www.resurge.org). To date Resurge has performed 95,000 operations in 15 countries. The times are different, but the issues are still the same. Opportunities with Resurge are described on their website.

We’re lucky in America. Despite criticisms of our medical system and its costs, the availability of outstanding medical care is just a few miles down the road for most of us. Interplast patients were elated to benefit from American medicine abroad.

Grady Harp, Amazon Hall of Fame Top 100 Reviewer

April 20, 2019

Once again Rick Novak serves up a virulent novel that addresses an ongoing change in medicine that worries most of us – the growing dependence on robotics in surgery and the dehumanization of medicine: doctor patient interaction is altered by EMR and IT reporting of visits to insurance companies and the warmth of communication suffers. Rick takes this information to create a story about the extremes of AI in the form of a glowing globe that is Dr Vita and the struggle computer scientist/anesthesiologist Dr Lucas assumes as he tries to save medicine from the extremes of the ‘new age’ called FutureCare. As expected, Rick’s recreation of the tension in the OR and in interaction of the physicians is on target: his own experiences enhance the veracity of the story’s atmosphere.

Rick Novak writes so extremely well that likely has answered the plea of his readers to continue this `hobby’. He is becoming one of the next great American physician authors – think William Carlos Williams, Theodore Isaac Rubin, Oliver Wolf Sacks, Richard Selzer, and also the Brits Oliver Wendell Holmes et al. Medicine and writing can and do mix well in hands as gifted as Rick Novak. Highly Recommended. Grady Harp, April 19

The first chapter of Doctor Vita by Rick Novak opens with a scene unlike any you’ve ever read before.

Chapter 1    THE BRICKLAYER

Alec Lucas’s first contact with FutureCare came in operating room #19 at the University of Silicon Valley Medical Center, where his patient Elizabeth Anderson blinked into the twin suns of the surgical lights hanging from the ceiling. A clear plastic oxygen mask covered Elizabeth’s nose and mouth, her cheeks were pale and tear-stained, and a strand of gray hair protruded from a blue paper bonnet. Her hand trembled as she reached up to remove the mask.

“I’m scared,” she said.

“I’m not,” said Dr. Lucas, who was her anesthesiologist. A green paper mask covered his face, but his pale blue eyes sparkled at her. He hummed to himself as he injected a dose of midazolam into Elizabeth’s IV to relax her.

“Am I crazy to go through this?” she said. “A 78-year-old lady with cancer?”

“We’re hoping your cancer can be cured with surgery,” Alec said. “Right now you’re doing great. Everything is perfect. Have a wonderful dream.” Elizabeth had cancer of the stomach, and presented today for robot-assisted laparoscopic surgery to remove half her stomach. It was a huge surgery—a risky surgery. Alec wondered why they were doing this operation on this lady. He questioned the aggressive strategy for a woman this old, but his job was to anesthetize, not to philosophize.

He’d seen presurgery anxiety like hers hundreds of times. The best way to cure her fears was to get her off to sleep. He injected doses of propofol and rocuronium into her intravenous line. The drugs flowed into Elizabeth’s arm, and within ten seconds her eyes closed. He inserted the lighted blade of a laryngoscope into her mouth, and visualized the white and shining upside-down “V” of her vocal cords, hovering in a sea of pink tissue. He slid a hollow plastic tube between the cords and into the blackness of the trachea beyond. Then he activated the ventilator, which blew a mixture of oxygen and sevoflurane through the tube into her lungs.

“I haven’t worked with you before, Dr. Lucas,” said the circulating nurse, who stood at the patient’s side. “My name is Maggie.”

“Of course you’ve never worked with me,” he said. “I told the nursing supervisor I never wanted to work with Maggie.” Then he winked at her and said, “We haven’t worked together because today is my first day on staff here. I’ve been at the University of Chicago since my first day of medical school. After fifteen years of shoveling snow, it was time to give California a try.”

Alec looked up as the surgeon, Xavier Templeton, entered the room. A tall scrawny man, Templeton had pale hairless matchstick arms that looked better hidden within a surgical gown. His bushy eyebrows met in the midline, and his left eye squeezed in an involuntary tic. Templeton’s hands wouldn’t touch Elizabeth Anderson’s skin or stomach today. His hands would control two levers on a console worthy of a spacecraft, and each move he made would be translated into the movement of a five-armed machine named the Michelangelo III, also known as The Bricklayer.

The five slender mechanical arms of The Bricklayer, dull gunmetal gray in color, dangled like the legs of a giant spider above Elizabeth Anderson’s abdomen. Each arm was draped in clear plastic to keep The Bricklayer sterile when it entered her body through tiny incisions.

Alec accepted his role of goaltender at the Pearly Gates. His assignment was to keep Elizabeth Anderson asleep and alive, while Templeton and The Bricklayer resected her tumor.

Twenty minutes into the surgery, Xavier Templeton sat on a chair in the corner of the room with his back to the operating table, and peered into a binocular stereo viewer. His hands maneuvered two levers on the console before him. On the operating table, the five robot arms reached into the abdomen though five one-centimeter incisions. One of the arms held a camera on a thin metal rod, movable at the surgeon’s control. A seventh-year resident worked as a surgical assistant, and attached appropriate operating instruments to the other 18-inch-long robot arms.

The two surgeons murmured to each other in quiet voices. Alec watched the surgery on a large flat screen video monitor that hung above him. He saw pink tissues, robot fingers moving, and a lot of irrigating and blunt dissection. The surgery was going well, and Alec made only minor adjustments in his drug doses and equipment as needed.

Then one thing changed.

One of the robot fingers on the video screen convulsed in staccato side-to-side slicing movements of its razor-sharp tip. A clear plastic suction tube exiting from the patient’s abdomen lurched and became an artery of bright red blood. The scarlet tube emptied into a bottle two feet in front of Alec. In sixty seconds the three-liter bottle was full of blood. Fifty-eight seconds prior to that, Alec was on his feet and both hands were moving. A flip of a switch sent a stream of fluid through the biggest IV into the patient. He turned off all the anesthesia gases and intravenous anesthetic medications.

“Big time bleeding, Dr. Templeton,” Alec shouted to the surgeon.

As fast as he could infuse fluid into two IVs, Alec could not keep up with the blood loss draining into the suction tube. The blood pressure went from normal to zero, and a cacophony of alarms sounded from the anesthesia monitoring system.

Templeton descended from his perch on the far side of the room, and put on a sterile gown and gloves. He took a scalpel from the scrub tech, and in one long stroke made an incision down the midline of the abdomen from the lower end of the breastbone to the pubic bone. With two additional long swipes, the left and right sides of Elizabeth Anderson parted. A red sea rose between them. The surgical resident and the scrub tech held suction catheters in the abdomen, but the stream of blood bubbled upward past the catheters. Templeton cursed and reached his right hand deep to the posterior surface of the abdominal cavity, feeling for the blood vessel on the left side of the spinal column. He found it, and squeezed the empty and pulseless aorta.

Alec looked at the monitors. The blood pressure was zero, and the electrocardiogram showed the heart was whipping along at a rate of 170 beats per minute. His patient had one foot in the grave. “Have you got control up there?” he screamed at Templeton.

“God damn it! I’m squeezing the aorta between my fingers,” Templeton answered. “As soon as I can see, I’ll put a clamp on the vessel. The bleeding is everywhere. I can’t see a damn thing.” Templeton’s face, mask, hat, and gown were drenched with the blood of Elizabeth Anderson. His unibrow was a red and black dotted line.

“Fire up the Maytag,” Alec said to Maggie. “Call the blood bank and activate the massive transfusion protocol.” Alec bent over the Maytag, a rapid blood infusion device with a bowl the size of a small washing machine. He turned the Maytag to its top flow rate. The machine hummed and spun, and the basin of IV fluid emptied into Elizabeth Anderson through a hose as wide as a small hot dog.

Despite the infusion of fluid, her blood pressure peaked at a dismal 65/40. “Have you found the hole yet?” he said to Templeton.

“Torn aorta. There are multiple holes—the aorta’s leaking like a sprinkler hose,” Templeton said without looking up. His left eye was blinking and squeezing repeatedly as he worked. “It’s terrible. The inferior vena cava is shredded and the blood from the lower half of her body is pouring out into her abdomen. The blood is everywhere.” Blink, squeeze. “Her vessels are falling apart like tissue paper.”

An orderly ran into the operating room carrying a red plastic beer cooler. Alec grabbed the cooler and popped off the top. Inside were six units of packed red blood cells, six units of fresh frozen plasma, and six units of platelets from the blood bank. “Check all the units and let’s get them flowing,” he said to Maggie.

Maggie picked up each bag and double-checked the patient’s name and the unit numbers with a second nurse, and then she handed the entire cooler to Alec. He drained each of the units of blood products into the basin of the Maytag, and the bowl hummed and pumped the blood into Elizabeth Anderson. The blood pressure began to climb, but one look at the crimson suction tubes exiting the patient’s stomach told Alec they were still in trouble. The bleeding wasn’t slowing. Blood was exiting faster than he could pump it in.

“We need a second cooler of blood products stat!” he said. Maggie picked up a telephone and relayed the order to the blood bank.

Alec looked at the surgical field, and the patient’s blood was everywhere—on Templeton’s face, hands, gown, on the surgical drapes and on the floor. It was everywhere but where it needed to be—inside her blood vessels. Templeton’s resident was jamming a suction catheter into the abdomen next to Templeton’s fingers, trying to salvage as much blood as he could.

“Damn it,” Templeton said. “She’s still bleeding, and now she’s bleeding pink piss water. I can see through her blood, it’s so dilute. How much fluid have you given her?”

“Six units of blood, six units of plasma, six units of platelets, and eight liters of saline.”

Alec glanced at the monitors and saw that her blood pressure had plateaued at a near-lethal level of 40/15.

“Her blood isn’t clotting anymore,” Templeton said. “The blood’s oozing and leaking everywhere I place a suture.”

Alec palpated her neck, and there was no pulse. “She has no blood pressure and no pulse,” he said. “We need to start CPR.”

Templeton’s resident placed the palms of his hands on Elizabeth Anderson’s breastbone and began chest compressions. The patient’s heart rate of 180 beats per minute slowed to 40 beats per minute, with premature beats and pauses between them. After twenty seconds of a slow irregular rhythm, her heartbeat tracing faded into the quivering line diagnostic of ventricular fibrillation.

Alec injected 1 milligram of epinephrine, and screamed, “Bring in the defibrillator.”

A second nurse pushed the defibrillator unit up to the operating room table. Templeton charged the paddles, applied them to the patient’s chest, and pushed the buttons. Elizabeth Anderson’s body leapt into the air as the shock of electrical energy depolarized every muscle of her body. All eyes turned to the ECG rhythm, and it was worse than ever.

Flat line.

“Damn it. Give me the scalpel back,” Templeton said. He carved a long incision between the ribs on the left side of Elizabeth Anderson’s chest, and inserted his hand into her thorax.

“I have her heart in my hand and I’m giving her direct cardiac massage,” he said. Alec looked at the monitors, and the direct squeezing of the heart was doing nothing. The blood pressure was still zero, and now blood was oozing from the skin around her IV sites, as well as from the surgical wounds in her abdomen.

Elizabeth Anderson’s heart was empty. Her blood vessels were empty. Her blood pressure had been near-zero for twenty-five minutes.

“What do you think, sir, should we call it?” Templeton’s resident said.

Templeton pulled his hand out of Elizabeth Anderson’s chest, and looked at the clock. “I pronounce her dead, as of 8:48 a.m. Damn, damn, damn it!”

Alec reached over and turned off the ventilator. The mechanical breathing ceased, and there was nothing left to do. He looked down at Elizabeth Anderson’s bloated face. Two strips of clear plastic tape held her eyes fastened shut, and her cheeks were as white as the bed sheet she rested on. A length of pink tape held the breathing tube fixed to her upper lip, and blood oozed from her nose and from the membranes between her teeth. This lady walked into the University of Silicon Valley Medical Center today hoping for a surgical miracle, and instead she was going to the morgue looking like this.

Xavier Templeton peeled his gloves off. “Goddamn it! The fricking robot went berserk. Sliced into the artery like a goddamned hedge trimmer. Now I have to tell the family she’s dead. Goddamn damn it!” He scowled in Alec’s direction. “Are you coming with me, Dr. Lucas?”

Alec nodded a yes. He looked at the gloomy outline of The Bricklayer’s arms, and then back at Templeton. Templeton was a fool to blame the medical device for his own ineptitude. The machine could do no wrong on its own.

This was the surgeon’s fault. Alec had heard it all before. Accept compliments and deflect all blame—it was an adage as old as the profession of surgery.

Templeton commanded The Bricklayer. And The Bricklayer was no better than the human hands that led it.

THE ANESTHESIA CONSULTANT

Which anesthesia fellowships are most popular? How many anesthesia residents choose further subspecialty fellowship education at the end of their residency, and which subspecialties are those graduates choosing?

The grid below, published in the California Society of Anesthesiologists Vital Times 2018, lists the fellowship choices from the last five years of Stanford anesthesia resident graduates:

IMG_7419.jpg

The totals from most popular to least popular fellowship choices from this grid are as follows:

SUBSPECIALTY:

Cardiac anesthesia                17

Regional anesthesia              14

Pediatric anesthesia              12

ICU/critical care                        10

Pain medicine                             8

Research                                         8

Obstetric anesthesia               2

Neuro anesthesia                      1

ENT/airway                                    1

Transfusion medicine            1

Palliative care                              1

TOTAL                                             75

Approximately 28 residents graduate from Stanford each year, for a total of 140 graduates over five years. If 75 out of 140 graduates pursued fellowships, then approximately 53% of residents chose fellowships, while 47% entered the workforce without further fellowship training.

I’m a private practice/community anesthesiologist who also practices in a major university medical center at Stanford, and I have some reflections on this data. The fact that 47% of the graduates do not pursue subspecialty fellowship training doesn’t surprise me. If an anesthesiologist proceeds directly through college, medical school, internship, and then a three-year residency, he or she will be at a minimum 30 years old. Twelve years of post-high school education is enough for many graduates, and the desire to earn a paycheck can trump any desire to complete any more training. A board-eligible anesthesiologist without a fellowship can find a job in most geographical areas without difficulty. In a competitive marketplace such as the San Francisco Bay Area, I believe an anesthesiologist with fellowship training gains an advantage in the search for a plum job over someone who did not complete a fellowship.

Let’s look at the fellowships Stanford graduates chose, and discuss the merits of each subspecialty as of 2019:

220px-Cvt_anesthesologist

Cardiac anesthesia continues to be popular. Stanford has outstanding cardiac surgery and cardiac anesthesia departments. The technology and challenges of cardiac anesthesia tend to draw ambitious residents into this subspecialty. I practiced cardiac anesthesia for 15 years. Those years were notable for very early morning arrival at the hospital (circa 6 a.m.), lots of invasive anesthesia preoperative procedures (arterial lines, central venous pressure catheters, pulmonary artery catheters, and transesophageal echocardiography), long complicated surgeries, sick patients, takebacks for bleeding in the middle of the night, and several surgeons with demanding difficult personalities. The field of cardiac surgery has changed dramatically since the 1980s and 1990s, when one of my surgical colleagues then lamented, “What’s the difference between a cardiac surgeon and a dinosaur?” His answer was, “Nothing.” In the 1980s invasive cardiologists began inventing techniques to apply balloons and stents in the coronary arteries to replace the open-chest coronary artery bypass grafting that cardiac surgeons used to do. Today even valve replacements can be done by cardiologists. Today cardiac surgeries are primarily difficult tertiary cases and revision procedures, i.e. cases that cardiologists cannot fix via intravascular access.

Regional anesthesia is a growing field. Both academic and community anesthesia groups need individuals with expertise in ultrasound-guided regional blocks. Regional anesthesia specialists should have no trouble finding jobs.

pediatricanesthesia

Pediatric anesthesia specialists are found in every large anesthesia department. Pediatric hospitals need fellowship-trained graduates on their staff, but for private/community groups, the role of fellowship-trained pediatric anesthesiologists depends on the volume of pediatric surgery. Community groups often expect multiple anesthesiologists to cover routine pediatric cases (e.g. age 1 and over) when they are on call. If only 10% of cases are pediatric and those cases sometimes occur on weekends or at night when an on call anesthesiologist will staff the cases, it’s unlikely the group will hire a specialist pediatric anesthesiologist to be on call every night. For a large group, this may be possible, but for a smaller group, it may not.

Respiratory_therapist

ICU/critical care medicine fellowships have always been popular at Stanford. For years the anesthesia department ran the intensive care units at Stanford, and these anesthesia/ICU attendings were outstanding role models. I decided to follow my internal medicine residency at Stanford with an anesthesia residency because I was so impressed with the ICU attendings and their training. The current Stanford anesthesiologist department chairman, Ron Pearl MD PhD, was initially a Stanford internal medicine resident who then completed the Stanford ICU fellowship, and after all that enrolled in and graduated from the Stanford anesthesia residency program. The unique value of an ICU fellowship is that you attend to sick patients of every type, and you become comfortable managing the most demanding medical situations day and night. ICU/critical care graduates are become outstanding clinical anesthesiologists who add value in either an academic or a community setting. Note that in a private/community practice setting, the clinical work in an ICU setting often becomes secondary to operating room anesthesia work, because there have always been superior financial reimbursements for the time anesthesiologists spend in the operating room versus the time they spend in the ICU.

epidural-injections

Pain medicine is a vast frontier for anesthesiology. The anesthesia department at Stanford renamed itself the Department of Anesthesiology, Perioperative and Pain Medicine to emphasize the inclusion of pain medicine within our specialty. While the clinical features of operating room anesthesia care have changed very little in recent decades, the possibilities for research and growth in pain medicine are limitless. As an internal medicine doctor, I can tell you that almost everyone hurts in some part of their body, and the treatments for pain, especially for chronic pain, are still in their infancy. Opioid medications work for a while, but patients can become tolerant and addicted to the drugs. More specific pain treatments without the opioid side effects of respiratory depression, addiction, constipation, and nausea are desperately needed. The potential for basic science research in pain medicine is unequaled in any other field of anesthesia. In either community or academic practice, pain doctors staff pain clinics where other physicians can refer their most difficult and unhappy patients. Pain clinic waiting rooms are rarely empty.

Research fellowships are a launching pad to an academic career. Selecting an outstanding mentor is a key factor. If a mentor is known to publish extensively, he or she can teach their fellow how to select important projects, design experiments and studies, write grants, write research papers, and get those papers published. Basic science laboratory research is becoming the domain of investigators with PhDs. Significant clinical research is done primarily by MD anesthesia faculty members at universities. The reputation of a professors is judged by the extent of their publishing and research. Research fellowships are not an important step to a career in private/community clinical medicine.

obanesth

Obstetric anesthesia is a valid subspecialty in academic centers. In private/community jobs, it’s expected that all anesthesiologists who are on call on weekends and nights can handle both routine and emergency obstetric cases. Completing an OB fellowship isn’t a direct link to landing a graduate an outstanding community job—almost every community anesthesiologist will be expected to have to have OB skills.

2-craniotomy-brain-surgery-dr-p-marazziscience-photo-library

Neuro anesthesia training will prepare a graduate for a wide array of brain surgery cases. This specialty will be valued in an academic practice or in a private/community group that does a large amount of neurosurgery.

Awake-Intubation.001

In Ear, nose and throat/airway subspecialty training, a graduate will gain expertise in managing difficult airway cases. This field will appeal to graduates seeking an academic job doing complex head and neck surgical cases.

I don’t have access to national data on the distribution of fellowships in graduates of anesthesia programs other than Stanford. While it’s possible that Stanford is an atypical peer group, I hope this analysis of the fellowships Stanford graduates choose gives you a better idea of the career choices available to anesthesia residents.

8-YEAR-OLD CONGOESE BOY DIES FROM ANESTHESIA. WHAT HAPPENED?

THE ANESTHESIA CONSULTANT

8-year-old Matadi Sela Petit, who journeyed from the Democratic Republic of Congo to Los Angeles for surgery, died at Cedars-Sinai Hospital on December 16, 2018, from what has been described as “a rare genetic reaction to the anesthesia.” Matadi was born with a cleft lip and a tumor on the left side of his face/cheek that grew into the size depicted in this photograph:

Matadi-Sela-Petit

Matadi Sela Petit

The Dikembe Mutombo Foundation, created by retired National Basketball Association star Dikembe Mutombo, sponsored the boy to come from Congo to the United States for the surgery. Matidi’s cleft lip was treated earlier with help from the foundation.

According to The Washington Post, “The Dikembe Mutombo Foundation . . . headed by the former NBA star said that during the delicate surgery on Dec. 16, the boy suffered a rare and unexpected genetic reaction to anesthesia.”

This was a tragic outcome, and my sympathies go out to the patient’s family, to the Foundation, and also to the physicians who treated the boy. Cedars-Sinai is an outstanding medical center—one of the finest in the United States—and has a reputation of having an outstanding medical staff.

What “genetic reaction” could have occurred during the anesthetic? No details have been released in the press, and readers are left to puzzle over what went wrong. As a practicing pediatric anesthesiologist, I’m interested in what happened. I have no access to medical records, nor any inside information on the case, but based on my education and experience my impressions follow below.

Regarding “a rare and unexpected genetic reaction to anesthesia,” the phrase used in the press release to describe the event, I see these possibilities:

  1. Malignant Hyperthermia. Malignant Hyperthermia (MH) is a disease in which a severe reaction occurs during general anesthesia, only among patients who are genetically susceptible. Symptoms include hypermetabolism, muscle rigidity, high fever, acidosis, sudden high blood potassium levels, and a risk of cardiac arrest. MH can only occur in patients who have the genetic predisposition to the disease, and who are then exposed to a potent anesthetic gas (e.g. sevoflurane, desflurane, or isoflurane), or the intravenous muscle relaxant succinylcholine. The treatment for MH involves emergency intravenous injection of the antidote dantrolene, immediate cooling of the patient, and immediate treatment for acidosis and elevated potassium concentration. The treatment for MH is usually effective if the diagnosis is made promptly. The quoted mortality rate for MH is now less than 5%. A potent anesthetic gas such as sevoflurane is commonly used in most pediatric anesthetics, and could have been used in Matidi’s case. Succinylcholine carries a Black Box Warning from the U.S. Food and Drug Administration regarding its use in pediatric patients, and it was unlikely to be used in this Matidi’s anesthetic. Even if Matidi had a previous surgery for his cleft palate, it is not unheard of for a patient to fail to develop MH on their first exposure to potent inhaled anesthetics, and yet develop MH on a later exposure.
  2. An occult muscular dystrophy. A patient who has an undiagnosed genetic muscular dystrophy can develop a sudden cardiac arrest after the administration of the muscle relaxant succinylcholine. Administration of succinylcholine to a patient with an occult muscular dystrophy can cause sudden cardiac arrhythmias, and for this reason succinylcholine carries a Black Box Warning from the U.S. Food and Drug Administration, restricting its use in pediatric patients to emergencies. Because of the Black Box Warning against using succinylcholine in pediatric anesthesia, it is unlikely succinylcholine was used in this patient’s anesthetic.
  3. The mass effect of the tumor in this patient’s face. If one can assume Matidi was born with this tumor, then the existence of this congenital mass lesion next to his airway and breathing passages is a genetic issue. From the photograph of Matidi, the tumor dominated his face. The tumor pushed his mouth to the right, and likely encroached on breathing anatomy. Once general anesthesia is induced, large tumors like this can compress the airway further. Every general anesthetic requires safe management of A-B-C, or Airway-Breathing-Cardiac, in that order. A child such as Matidi with markedly abnormal facial anatomy brings the risk of the loss of control of the airway at any point during the anesthesia or surgery. Loss of airway means there is no clear path for oxygen to traverse from the anesthesia machine through the head and neck to the lungs. Lack of oxygen to the lungs can lead to lack of oxygen to the brain and heart. Five minutes of oxygen depletion to the brain can cause anoxic brain damage. Oxygen depletion to the heart can cause cardiac arrest. Airway problems related to congenital diseases are discussed in the article Specific Genetic Diseases at Risk for Sedation/Anesthesia Complications, in the journal Anesthesia & Analgesia.

After scouring the world’s anesthesia literature and textbooks, I can find no other plausible “genetic reaction to anesthesia” to explain this patient’s death.

This patient’s care will be discussed in peer review and quality assurance committees at the hospital where the event occurred. There is always an autopsy on any unexpected death in an operating room, and more information may come from that. But whenever there is an adverse patient outcome, for medical-legal reasons, do not expect the healthcare professionals to reveal the specifics of what happened to the outside world.

DOCTOR VITA AND THE BS IN HEALTHCARE

THE ANESTHESIA CONSULTANT

Last week Lawton Burns PhD and Mark Pauly PhD of the Wharton School of Business at the University of Pennsylvania published a landmark economic article entitled, “Detecting BS in Health Care.” Yes, you did not read that wrong—the academic paper used the abbreviation “BS” to describe the bull—- in the healthcare industry.

BS in Health Care

 

As a practicing physician, I find it to be a fascinating paper, and I recommend you click on the link and read it. The authors begin with a discussion of the art and value of BS detection. They mention that Ernest Hemingway was once asked, “Is there one quality needed to be a good writer, above all others?”

Hemingway replied, “Yes, a built-in, shock-proof, crap detector.”

The authors write, “While flat-out dishonesty for short term financial gains is an obvious answer, a more common explanation is the need to say something positive when there is nothing positive to say. . . . The incentives to generate BS are not likely to diminish—if anything, rising spending and stagnant health outcomes strengthen them—so it is all the more important to have an accurate and fast way to detect and deter BS in health care.”

The authors list their Top 10 Forms of BS in Health Care. The first four forms of BS weave a common theme:

  1. Top-down solutions: High-level executives and top management in the health care industry are supposed to engineer alternative payment models, but nothing has worked to date.
  2. One-size-fits-all, off-the-shelf: Leadership of industry and government assume one solution will work for multiple organizations, without customization.
  3. Silver-bullet prescriptions: A “silver bullet” is described as something that will cure all ills, and must be implemented because it been “decided that it is good for you,” Electronic health records (EHRs) are a prime example of a silver-bullet prescription. The federal government pushed the use of EHRs, claiming the systems would reduce costs and improve quality—but Burns and Pauly argue EHRs “eventually raised costs and only mildly touched a few quality dimensions.”
  4. Follow the guru: We must follow a visionary guru with a mystical revelation about what needs to be done. The authors describe how, in health care, Harvard professor Michael Porter and former CMS (Center of Medicare and Medicaid) administrator Don Berwick launched theories based on population health, and per-capita cost, to little success.

The current U.S. healthcare market is dominated by large corporations, led by businessmen who outline a yellow brick road for physicians to lead patients along. There is minimal effective policy-making from physicians. Healthcare stocks consistently grow in value, with little relationship to an improvement in clinical care, value, or cost. The government is involved as well, as in their mandate for Electronic Health Records (EHRs), a technology change that cost a lot of money, while forging a barrier between clinicians and the patients we are trying to interview, examine, and care for.

Where will the current trends take us? Will businessmen and/or the government prescribe health care? Will more and more computers and machines dominate health care?

Self-driving cars, Siri, Alexa, automated checkouts at Safeway, and IBM’s Watson are technologic realities. Will we someday see a self-driving physician with the voice of Siri and the brains of Watson?

Call that device “Doctor Vita.”

The saga of Doctor Vita arrives in 2019 from All Things That Matter Press.

Is sublingual sufentanil dangerous? The United States Food and Drug Administration (FDA) voted to approve the narcotic sufentanil for sublingual use in November of 2018. Sublingual sufentanil is 5-10 times more potent than fentanyl, and dissolves under the tongue in seconds.

saupload_12987447_a7_thumb1

In an era of opioid overdose crisis, we now have a new, even more potent pill form of opiate.

Opioid deaths 1999-2017Sublingual sufentanil is approved for use only in medical settings, for the treatment of moderate to severe acute pain. But it is also possible that sublingual sufentanil will become the most dangerous street opiate ever known. This column reviews the arrival of sublingual sufentanil, from the viewpoint of a practicing anesthesiology attending.

Raeford Brown, Jr., MD, chair of the Anesthetic and Analgesic Drug Products Advisory Committee, and professor of anesthesiology and pediatrics at the University of Kentucky, disagreed with the FDA approval for sublingual sufentanil, citing the drug’s risk for “diversion, abuse, and death.” He cited the possible harms of such a “dangerous” drug — estimated to be 500-600 times more potent than morphine — coming to market in a tablet form. He warned of the risks of diversion of sufentanil by anesthesiologists and other medical personnel. He was quoted, “Sufentanil is a very potent opioid that is in a preparation that will be easily divertible. In the IV formulation, it has been a drug of abuse for health care providers.”

I agree with Dr. Brown. Sublingual sufentanil raises dangerous concerns. Sublingual sufentanil has the potential become the hydrogen bomb of all opiates—the mother of all lethal street drugs.

I have extensive experience administering intravenous sufentanil to patients. Intravenous sufentanil was FDA-approved in 1984. Its original primary use was as an anesthetic for cardiac surgery. I practiced cardiac anesthesia from 1985 until 2000. In the 1980s, cardiac anesthesia was achieved by high dose narcotic techniques, specifically with high dose fentanyl (100 micrograms/kg) techniques. For a 70-kilogram patient, this required injecting 7000 micrograms of fentanyl, or 140 ml of fentanyl (nearly two and an half sixty-milliliter syringes full of fentanyl) at the time of anesthetic induction. When intravenous sufentanil was approved at the same 50 mcg/ml concentration as fentanyl, but with a potency of 10 X of fentanyl, the narcotic induction only required 14 ml of sufentanil total. I can still remember my wide-eyed professors saying, “With sufentanil, the entire cardiac anesthetic is here in one syringe.” The use of sufentanil for cardiac anesthesia faded as anesthesiologists began using lower doses of narcotic as part of early-extubation techniques in the late 1990s.

We also used intravenous sufentanil to supplement anesthesia for non-cardiac surgeries. The most common method was to dilute the sufentanil 10:1 with saline, to a concentration of 5 mcg/ml. At this concentration, sufentanil was indistinguishable from fentanyl at 50 mcg/ml. After several years it became apparent that there was no advantage of using sufentanil IV over fentanyl IV in non-cardiac anesthesia, and the administration of IV sufentanil dwindled. The intravenous sufentanil form of the drug was also approved for epidural anesthesia. Over time, the use of sufentanil for epidural anesthesia also decreased, also supplanted by fentanyl.

Just when it looked like sufentanil was a drug nobody really neededà enter AcelRx Pharmaceuticals, a San Francisco Bay Area company which manufactured and tested a sublingual sufentanil product designed to melt under a patient’s tongue. Pamela Palmer, the founder and Chief Medical Officer of AcelRx, received her MD and PhD at Stanford, and is an acquaintance of mine. Dr. Palmer is an anesthesiologist who is brilliant and well informed regarding the pharmacology of sufentanil and the use of sufentanil in anesthetic practice.

Because sufentanil is highly lipid (fat) soluble, it is quickly absorbed into the bloodstream through the mucosal lining of the mouth. AcelRx will market the drug under the name Dsuvia, in a sublingual sufentanil tablet system (SSTS) which consists of a single-dose applicator prefilled with a single 3-mm-diameter 30-mcg tablet, administered by a healthcare professional no more frequently than hourly.

sublingual sufentanil

A radio frequency identification (RFID) cartridge, requiring the patient’s thumbprint, helps reduce unauthorized dosing. The device is tethered to the patient’s bed to reduce risk of product loss. Each tablet is pre-loaded into a single-dose applicator within a pouch so it is suitable for field/trauma use. Both the fixed drug and dose and lockout time interval eliminate the end-user programming error risk associated with Patient Controlled Analgesia (PCA) intravenous narcotic pumps.

Studies documented the efficacy and safety of the SSTS in the treatment of postoperative pain in patients following open abdominal surgery compared with placebo.

SSTS was rated a success by significantly more patients when compared to intravenous PCA morphine. There was a faster onset of analgesia and both higher patient and nurse satisfaction scores with the SSTS as measured by validated questionnaires.

Dsuvia will be marketed as “postoperative, sublingual, patient controlled analgesia.” Once administered under the tongue, the sufentanil tablets typically dissolve within 5  minutes. The FDA approved the drug to be used in hospital settings only, for the treatment of moderate-to-severe acute pain, where a narcotic is needed and rapid onset is desired, but the route of administration does not require intravenous access. Typical settings would be the surgical wards after major orthopedic or general surgery procedures. The chief competition for Dsuvia will likely be Patient Controlled Analgesia (PCA) intravenous narcotic pumps, a commonly used analgesic method in which patients push a bedside button and self-administer intravenous narcotic (e.g. morphine, fentanyl, or Dilaudid) on demand through their IV line.

The most significant risk involving sublingual sufentanil is its potency, specifically its extreme potency as a respiratory depressant. The product description by AcelRx states that sufentanil has a “high therapeutic index” of 26,716. The Therapeutic Index is the ratio that compares the blood concentration at which a drug becomes toxic and the concentration at which the drug is effective. The larger the therapeutic index (TI), the safer the drug is. The TI affirms that sufentanil toxicity starts at a concentration of 26716 times its therapeutic concentration, but this ignores the risk of respiratory depression at much, much lower doses. A patient treated with an overdose of sufentanil will stop breathing at a dose only slightly greater, i.e. in the ballpark of only 2 – 4 times greater, than its therapeutic concentration. Like all opiates, sufentanil has side effects of respiratory depression, sedation, nausea and constipation. Respiratory depression is the reason why opiate overdose patients die. Opiate overdoses do not cause death because of an inherent “toxicity” of the drug concentration in the blood, but rather because of respiratory depression. People simply stop breathing.

Regarding sufentanil, the National Institute of Health website states: WARNINGS: Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Sufentanil Citrate injection should be administered only by persons specifically trained in the use of anesthetic drugs and the management of the respiratory effects of potent opioids, including respiration and cardiac resuscitation of patients in the age group being treated. Such training must include the establishment and maintenance of a patent airway and assisted ventilation. Adequate facilities should be available for postoperative monitoring and ventilation of patients administered anesthetic doses of Sufentanil Citrate Injection. It is essential that these facilities be fully equipped to handle all degrees of respiratory depression. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical status.

There is also hope that sublingual sufentanil will have battlefield applications. A statement from FDA Commissioner Scott Gottlieg, MD on November 2, 2018 read: “(Sublingual sufentanil) has some unique features in that the drug is delivered in a stable form that makes it ideally suited for certain special circumstances where patients may not be able to swallow oral medication, and where access to intravenous pain relief is not possible. This includes potential uses on the battlefield. For this reason, the Department of Defense (DoD) worked closely with the sponsor on the development of this new medicine. This opioid formulation, along with Dsuvia’s unique delivery device, was a priority medical product for the Pentagon because it fills a specific and important, but limited, unmet medical need in treating our nation’s soldiers on the battlefield. The involvement and needs of the DoD in treating soldiers on the battlefield were discussed by the advisory committee . . . The FDA has made it a high priority to make sure our soldiers have access to treatments that meet the unique needs of the battlefield, including when intravenous administration is not possible for the treatment of acute pain related to battlefield wounds.”

In conclusion, will sublingual sufentanil be dangerous or not?

My assessment of sublingual sufentanil, based on the information above, is as follows:

  1. Sublingual sufentanil (SS) can be useful in hospitalized post-operative patients following major, painful surgeries such as orthopedic total joint replacements or intra-abdominal surgeries. SS could replace PCA intravenous morphine or fentanyl.
  2. The market share, or prevalence of SS use will largely depend on its cost versus intravenous PCA units. AcelRx will market the drug beginning in early 2019, at a wholesale price of $50 to $60 per dose.
  3. SS will not be frequently used in Post Anesthesia Care Units, Intensive Care Units, or the Emergency Department, because patients in these settings all have intravenous lines in place, and can receive traditional IV narcotics as needed. There is no need or demand for a sublingual narcotic product in these settings.
  4. If SS tablets are diverted or stolen and are taken outside of medical settings, they can cause death. Overdoses as low as two to four times a therapeutic dose could cause respiratory depression and death. If hospital personnel divert the drug for recreational use, these personnel will be at high risk for mortality.
  5. If SS ever reaches the streets as a recreational drug or heroin substitute, users will achieve opiate overdose and death at a very high rate. If anyone naively believes the drug will not reach the streets, consider that manufactured forms of all the other pill forms of opiates, i.e. Percocet, Vicodin, and Oxycodone, eventually reached the streets. What will prevent this new drug from doing the same?
  6. Efforts to educate street users regarding the dangers of this new drug will likely fail. There can be no safe use of SS outside a medical setting. People will likely overdose and die.
  7. Regarding battlefield use: In military settings where IVs are not common, the capacity to administer potent sublingual narcotic may become standard. But misuse and abuse in the military and on the battlefield are also possible. Tales of rampant drug abuse by soldiers in the Vietnam War are part of the lore of that conflict. Access to sublingual sufentanil in the military would need to be strictly confined and monitored.
  8. An added note: An intentional overdose with SS is probably an outstanding drug for physician-aided suicide.

I have no crystal ball, but the bottom line is this:

If sublingual sufentanil use is confined to acute care hospital settings, it will be useful and not dangerous. But if sublingual sufentanil reaches the streets as a drug of abuse, it will be lethal.

Time will tell which of these fates is the truth.

FRONT OF NECK ACCESS

THE ANESTHESIA CONSULTANT

Can you perform an emergency surgical cricothyroidotomy? In the dreaded Can’t Intubate, Can’t Oxygenate (CICO) scenario, if your patient has no airway, you must immediately establish a front of neck access (FONA) to save your patient’s life.

SCALPEL, BOUGIE, TUBE APPROACH TO CRICOTHYROIDOTOMY

SCALPEL, BOUGIE, TUBE APPROACH TO CRICOTHYROIDOTOMY

This week I attended an outstanding Stanford Anesthesia Grand Rounds delivered by Drs. Jeremy Collins, Susan Galgay, and Tom Bradley. The lecture reviewed the literature regarding CICO events, and concluded that performing a surgical airway through the cricoid membrane is an essential skill for anesthesiologists.

Most anesthesia professionals have never cut into a patient’s neck, but we must own this skill if the necessity arises. I’ve done thousands of cases over 34 years. I have never performed a surgical cricothyroidotomy, but I may need to do one tomorrow. It’s essential expertise for myself and for every anesthesiologist.

As I’ve reviewed in previous columns, a lack of oxygen to the brain for five minutes can cause anoxic brain damage—a disaster all anesthesiology professionals must avoid. The specter that someday we will induce and paralyze a morbidly obese patient, and then be unable to intubate or oxygenate that patient, is in the back of the mind of every anesthesia professional. If and when this happens, we must be able to act without hesitation to oxygenate the patient via FONA.

CICO events are rare, but they do occur with a published incidence of 1 in 50,000 anesthetics, per the fourth national audit project in the United Kingdom (NAP4).  Approaches to FONA include either cannula techniques or surgical techniques, with significant differences.

Cannula Techniques:

These involve inserting a large bore IV catheter through the cricothyroid membrane. Because the lumen of a 14-gauge IV catheter is small, ventilation requires a high- pressure jet oxygen delivery system. In Duggan’s publication from 2016, the failure rate with cannula techniques was 42% in CICO emergencies. In addition, barotrauma occurred in 32% of CICO emergency procedures. Fifty-one percent of CICO emergency events managed with a FONA cannula had a complication. Several reports described trans-tracheal jet ventilation-related subcutaneous emphysema hampering subsequent attempts at surgical airway or tracheal intubation. Failure can also occur because of kinking, malposition, or displacement of the needle/cannula. The Stanford Anesthesia Grand Rounds concluded that these failure rates and complications with cannula FONA techniques were prohibitively high.

Surgical Techniques:

The cricothyroid membrane is divided by a surgical incision made with a wide scalpel (#10 scalpel). With the scalpel, bougie, tube (SBT) technique, a bougie is inserted into the trachea through the incision. A lubricated 6.0 mm cuffed endotracheal tube is advanced over the bougie into the trachea, and the bougie is removed.

There are contrasting difficult airway algorithms algorithms for different English-speaking countries around the globe. See this link for the algorithms from the United States, Australia, Canada, and United Kingdom. Each has unique recommendations for CICO emergencies.

The American Society of Anesthesiologists Difficult Airway Algorithm outlines an approach to airway management, but at the bottom right of the chart, the plan for the CICO situation is “Emergency Invasive Airway Access.” A footnote reads “invasive airway access includes surgical or percutaneous airway, jet ventilation, and retrograde intubation.” The algorithm gives no definitive choice of which technique to use. This is a shortcoming of the American algorithm. There are invasive airway options, and in an emergency there can be no wavering or doubts regarding what to do. Per the data above, percutaneous airway and jet ventilation carry high failure and complication rates. Per discussion at the Stanford Anesthesia Grand Rounds, retrograde intubation is too slow, too difficult, and should be eliminated from the recipe for emergency lifesaving treatment.

The Australian algorithm uses the Vortex approach to managing an unexpected difficult airway.

the vortex approach

THE VORTEX APPROACH

Three options (face mask, endotracheal intubation, and laryngeal mask airway) are all attempted, in any order, to establish a patent airway. If all three methods fail to establish a patent airway, this (not the occurrence of oxygen desaturation) is the trigger to establish an emergency surgical airway (ESA). ESA techniques include either cannula or scalpel cricothyroidotomy to provide a patent airway as rapidly as possible. Note that the Australian Vortex approach endorses either cannula or scalpel cricothyroidotomy, and recommends that anesthesiologists be familiar with both FONA techniques.

The conclusions reached in the Stanford Grand Rounds most closely adhered to the British algorithm, which advocates the SBT (scalpel, bougie, endotracheal tube) method to securing a surgical airway. The SBT method has been specifically endorsed in the United Kingdom Difficult Airway Society algorithm. What follows is the text from the United Kingdom Difficult Airway Society guideline for a Can’t Intubate, Can’t Oxygenate event:

 

The United Kingdom Difficult Airway Society guideline for Failed intubation, failed oxygenation in the paralyzed, anaesthetised patient:

Fig5-Failed-intubation-failed-oxygenation-in-the-paralysed-anaesthetized-patient

Author’s addendum: Many or most patients who suffer CICO events will be obese and have thick or short necks. The cricothyroid membrane may not be easily palpable. Per the text above, the United Kingdom Difficult Airway Society guidelines recommend you make an 8-10 cm vertical skin incision, caudad to cephalad, over the cricothyroid area. This type of surgical maneuver is not a routine part of anesthetic practice, and it will require both skill and courage to commit to the incision. The guidelines next ask you to use blunt dissection with the fingers of both hands to separate tissues until you can identify the larynx and palpate the cricothyroid membrane. Once the cricothyroid membrane is identified, the scalpel incision is made through the cricothyroid membrane. This technique will no doubt create bleeding in the anterior neck, and will not be easy to perform. Enlisting the surgeon’s help during the procedure is advisable. Remember that controlling bleeding is not the primary issue—the primary goal is to locate the cricothroid membrane deep to the adipose of the anterior neck.

When I was a resident I was trained to give cricothyroid injections of lidocaine or cocaine to anesthetize the lumen of the trachea prior to awake fiberoptic intubations. The anatomy of the cricothyroid membrane in most patients is easily palpable, and it can be penetrated with minimal effort or bleeding. In a morbidly obese patient, this approach will be more difficult.

 

How to train anesthesiologists to perform SBT cricothyroidotomy:

This was the subject of discussion at the end of Grand Rounds. Because of the extreme rarity of CICO events, skills will be absent, lost, or dormant for many practitioners. Practice on simulators or plastic models at 6 months intervals was recommended. Dr. Bradley explained that in one approach in Britain, a two-person team traveled from operating room to operating room to teach the SBT method. One member of the teaching team relieved the anesthesiologist from the operating room, and the second member then took the anesthesiologist a room to enjoy a pot of tea and to learn from a plastic training model of the cricothyroid membrane. The final proposals for education and re-education to retain skills at Stanford and throughout the world are challenges for the future. Note that surgeons have almost no education at cricothyroid approaches. Head and neck surgeons are trained in tracheostomy, a different procedure that likely will take too much time to perform when compared to a cricothyroidotomy. Training of surgical colleagues also needs to be addressed in the future.

 

What You Should Do Now:

  1. Familiarize yourself with the anatomy of the cricothyroid membrane on each of your patients.
  2. Have an SBT kit containing a #10 scalpel, a bougie, and a #6 cuffed endotracheal tube included with each difficult airway cart at each facility you anesthetize at.
  3. I now carry an SBT kit in my briefcase which I take with me every day at work. In the current model of private practice in California, where we work at multiple different freestanding surgery centers and surgeon offices, this is a reliable means to assure that I have FONA equipment with me wherever I anesthetize patients.
  4. Be prepared. Review and rehearse the anatomy and skills necessary to perform front of neck surgical cricothyroidotomy in seconds.
  5. Work to avoid CICO events. Evaluate each airway prior to surgery. If a significant concern exists regarding a difficult intubation, a difficult mask ventilation, or a difficult FONA, use your judgment and perform an awake intubation. Securing an airway prior to anesthesia induction is a reliable way to avoid CICO disasters.

 

Two important take-home messages from this column are:

  1. Learn the specific the SBT recipe for front of neck access.
  2. Don’t hesitate and waste seconds—it will take courage to grab that scalpel, but that’s your job and your duty to your patient.

AUTISM AND ANESTHESIA

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Anesthetizing uncooperative patients is difficult. The combination of autism and anesthesia requires careful planning.

autism and anesthesia

Children or adults with psychological, developmental, or behavioral disorders such as autism may be combative or aggressive, and may require extra measures of preanesthetic sedation or restraint. The parents/guardians and the anesthesia team need to be actively involved with forming the preoperative plan for uncooperative patients.

The incidence of autism in the United States is high—the Autism and Developmental Disabilities Monitoring (ADDM) Network of the Center for Disease Control estimates about 1 in 59 children has autism spectrum disorder (ASD).

Characteristics of autism include developmental delays of behavioral and social skills, and an inability to communicate. The symptoms of ASD stretch across a broad range from mild to incapacitating.

It’s not infrequent that autistic patients need surgery and anesthesia. Patients with autism commonly need to be sedated for routine procedures that a normal child or adult would cooperate with. Dental cases are common, and are frequently referred to a hospital because the typical care systems at an outpatient surgery center or a dental office are inadequate to complete a successful anesthetic.

The most common anesthesia induction technique in children and toddlers is an inhalation induction with sevoflurane. The routine practice of performing an inhalational sevoflurane induction on a child with autism may be impossible.

The most common anesthesia induction technique in adults involves the intravenous injection of propofol. The routine practice of starting a preoperative IV to begin anesthesia care on an adolescent or adult with autism may also be impossible.

Let’s look at an example case of an uncooperative adolescent who is adult-sized and who requires an anesthetic:

A 16-year-old, 70-kilogram male with Autistic Spectrum Disorder is scheduled for dental surgery and teeth cleaning. He is verbal with his mother, but refuses to interact with the anesthesia or nursing personnel. He refuses to change into a hospital gown, or to remove his long-sleeved sweater. He refuses to drink or swallow any premedication, he refuses an IV, and he refuses inhalation induction. The mother, who is the patient’s legal guardian, consents to surgery and anesthesia, but she is unable to convince her son to cooperate with the medical team.

What do you do?

The surgical and anesthetic team spent significant time explaining, reassuring, and coddling the patient, to no avail. They told the mother she had the choice of going home without any surgical procedure or anesthesia at all. The mother was adamant that the procedure needed to be performed. To this end, all parties agreed to the following plan:

  1. Two hospital security guards were called to the bedside in the preoperative area.
  2. The two hospital guards and the mother donned white operating room coveralls.
  3. At the mother’s consent, the guards laid the patient down on the hospital gurney, held him there, and the surgical team and the guards pushed the gurney down the hallway to the operating room (a significant distance of approximately 100 yards).
  4. Upon arrival in the operating room, one of the security guards uncovered the sweater from the patient’s arm, and the anesthesiologist injected an intramuscular mixture of 2 mg/kg ketamine, 0.2 mg/kg midazolam, and .02 mg/kg atropine into the patient’s deltoid muscle. The patient protested, and the mother reassured him.
  5. The oximeter and routine monitors were placed.
  6. Once the patient became sedated (2-4 minutes later), the mother was escorted from the room and the anesthesiologist started an IV in the patient’s arm. The patient was then preoxygenated via mask in the standard fashion, propofol 1 mg/kg and rocuronium 0.5 mg/kg were injected IV, and the trachea was intubated.
  7. The surgery proceeded as scheduled, with sevoflurane as maintenance anesthesia.
  8. At the conclusion of surgery, the patient was extubated awake and taken to the Post Anesthesia Care Unit (PACU) in stable condition. The mother was reunited with the patient there. The patient was sedate, calm, comfortable, and tolerated the PACU care well.
  9. The patient was discharged home without complications after 90 minutes in the PACU. The mother was happy with the perioperative care.

Perhaps this practice of intramuscular induction of anesthesia sounds brutal to you.

The intramuscular (IM) ketamine/midazolam/atropine induction of anesthesia as described in the case study above is effective. In our practice, the recipe is the combination of 2 mg/kg of ketamine, 0.2 mg of midazolam, and .02 mg/kg of atropine.

The ketamine concentration is 100 mg/ml. The midazolam concentration is 5 mg/ml. The total volume of the intramuscular injection in our case study patient was 140 mg ketamine (1.4 ml), 14 gm midazolam (2.8 ml), and 1.4 mg atropine (1.4 ml), for a total injectate volume of 5.6 ml. More dilute concentrations of these three drugs will necessitate too large a volume for intramuscular injection. This IM induction technique is effective in safely inducing general anesthesia without an IV within 2-4 minutes, and has been described in a previous article on dental office anesthesia.

There are more gentle approaches to an uncooperative patient—approaches which this patient would not agree to. The literature lists these options for premedication or induction of anesthesia in uncooperative patients:

  1. Intranasal premedication sedation with either 0.5 mg/kg of midazolam, or 1 microgram/kg of dexmedetomidine were found to be equally effective in sedating 20 uncooperativechildren aged 2-6 years for dental treatment visits. 0.25 mg/kg of atropine, in combination with 0.5 mg/kg of midazolam, and 1-2
  2. Oral premedication sedation with 5 mg/kg oral midazolam. Oral sedation is considered as the oldest, easiest way of administrating sedative drugs to pediatric patients. Midazolam is a well-known sedative, and we use this often in our practice if the patient will accept it. The effect initiates within 20–30 minutes of oral administration.
  3. Oral premedication with dexmedetomidine 5 mcg/kg.
  4. Oral midazolam, ibuprofen, and 6 mg/kg of ketamine. Oral ketamine of  up to 8 mg/kg has shown to effective in improving compliance during induction of anesthesia. Compared with oral midazolam, oral ketamine causes less respiratory depression. Ketamine does cause nystagmus, increased salivation, hallucinations and emergence delirium. When used alone as a premedicant ketamine has not been found to be effective. There is no significant difference between oral ketamine and oral midazolam in the postoperative recovery or hospital discharge.

Uncooperative children or adults with ASD will each have individualized needs. Patients with significant ASD may have severe objections to the doctor-patient relationship, and it can take a prolonged time to gain their trust. It’s important to discuss the perioperative anesthetic issues and the preoperative plan with a parent or guardian well in advance of the surgical date if possible. The anesthesia team can determine the simplest means of preoperative sedation/anesthesia to complete the case successfully, and the family can give input regarding previous anesthesia successes or failures. It’s optimal if the family and the MDs can agree to an appropriate approach to the anesthetic, days prior to the actual surgery.

Parents often ask about the risk of general anesthesia to the brain of their child. At present there is no documented connection between exposures to general anesthesia and the development or worsening of autistic symptoms. In a study of a birth cohort of 114,435 children from Taiwan from 2001 to 2010, 5197 children under the age of 2 years were exposed to general anesthesia and surgery. The 1 : 4 matched control group comprised 20,788 children. The results showed that neither exposure to general anesthesia and surgery before the age of 2 years age, nor the number of exposures, were associated with the development of autistic disorder. 

Do autistic patients suffer more complications from anesthesia and surgery than non-autistic patients? In a review by Arnold published in Pediatric Anesthesia in 2015, other than a significant difference in the premedication type and route (per the discussion above), children with ASD had similar perioperative experiences as non‐ASD subjects.

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

NERVE BLOCKS AND NERVE INJURY

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Let’s discuss an elephant in the room of operating room anesthesia–the association between peripheral nerve blocks and nerve injury.

hqdefault

The use of peripheral nerve blocks has crescendoed in anesthesia practice, stimulated by the use of ultrasound-guided visualization of nerves. There are growing economic industries in ultrasound machines, ultrasound block needles, and in anesthesia personnel who bill for this additional optional procedure on orthopedic patients.

Ultrasound allows us to visualize the nerves, but there are no data demonstrating a lower neurologic complication rate with this ultrasound technique.(Liu SS, et al. A prospective, randomized controlled trial comparing ultrasound versus nerve stimulator guidance for interscalene block for ambulatory shoulder surgery for postoperative neurological symptoms. Anesth Analg. 2009;109:265-271).

The incidence of nerve injury following peripheral nerve block is low, but not zero. Per Gadsden, the mechanism of permanent nerve injury is felt to be either needle trauma, or toxicity of local anesthetics. In a review article by David Hardman MD MBA, of the University of North Carolina, the incidence of permanent injury rates, as defined by a neurologic abnormality present at or beyond 12 months after the procedure, ranges from 0.029% to 0.2%. This reviewed data came from old studies, dating from 2001 – 2012. There are no more recent published studies of large populations. Multiplying this 1/3000 to 1/500 incidence by the tens of thousands of nerve blocks performed yearly leads to a significant number of permanently damaged nerves.

In all likelihood, as of 2018, the incidence and number of permanent nerve injuries during this era of ultrasound-guided nerve blocks looms larger than any medical literature confirms. Why is this? I believe there are several reasons for the under-reporting of nerve injury following peripheral nerve blocks:

  1. Time lag in published data. The data in the medical literature regarding peripheral nerve injury following nerve block is old. In a lecture on this topic by David Hardman MD MBA at the American Society of Anesthesiologists (ASA) national convention in San Francisco, none of the data regarding nerve injury complication was more recent that 2007. Recent data is still unreported, and remains to be analyzed.
  2. Time lag in Closed Claims data. The ASA Closed Claims data always lags behind the occurrence of complications. A typical malpractice lawsuit takes a long time (e.g. 4 – 7 years) to come to a conclusion. The ASA Closed Claim database may be 10 years or more in arrears before it is finally published.
  3. Some peripheral nerve injuries never get reported to anyone. Either the patient never informs the physician, the case never gets tallied in any database, the physician never informs any quality assurance (QA) committee, or the case meets its termination in a QA committee discussion that goes no further.
  4. No one publishes case reports of their complications. Do you think an anesthesiologist is motivated to publish a case report in which they had permanent nerve injury of the brachial plexus following an interscalene nerve block for shoulder surgery? Of course not. He or she wants that case buried deeply, with as few people as possible knowing. No one publishes their dirty laundry, hence the medical literature is lacking in adverse case reports.
  5. Academic professors specializing in regional anesthesia have little interest in publicizing data that could damn or minimize the importance of their chosen subspecialty. A physician who makes his or her living performing, teaching, and writing about a hammer has a conflict of interest when it comes to speaking out on the dangers of wielding that hammer.

In my role as a peer review physician, quality assurance committee member, and simply as a physician in a busy medical system, I’m aware of more than a dozen patients who already have permanent nerve injury following an ultrasound-guided peripheral nerve block. None of their case histories has been published, and none of their cases have appeared in a published series of nerve injury complications.

Let me give you an example of another anesthesia technique that was associated with permanent nerve injury: In the 1990’s we routinely used hyperbaric 5% lidocaine for spinal anesthesia. Lidocaine had the advantage of supplying short (1 – 1 ½ hour) spinal anesthesia for simple cases such as cytoscopies, urethral surgeries, perineal surgeries, and inguinal hernias. Case reports of cauda equina syndrome emerged, in which some lidocaine spinal anesthetics were associated with inflammation of the distal spinal cord (cauda equina), which caused permanent lower extremity nerve injury. Because of this risk, the use of lidocaine spinal anesthesia disappeared. The risk of nerve injury was real, and the risk was too daunting to continue using that anesthesia technique.

“Complications of Peripheral Nerve Block,” an article published in the British Journal of Anaesthesia in 2010, stated that “complications of peripheral nerve blocks are fortunately rare, but can be devastating for both the patient and the anaesthesiologist.”

In his lecture on nerve injury complications of peripheral nerve block delivered at the 2018 ASA national convention in San Francisco, speaker David Hardman, MD MBA told a standing room only crowd of anesthesiologists that if your patient develops a permanent nerve injury following a peripheral nerve block, “you will be sued.” Why was there a huge crowd for this particular lecture? I believe it’s because many anesthesiologists are aware of the occurrence of nerve injury, and aren’t sure what to do about the incidence of ultrasound-guided nerve blocks in their practice.

No one wants to be sued, but per the Hippocratic Oath we must first do no harm. The real crisis is not that an anesthesia provider gets sued, but that the patient will go the rest of their lives without the normal use of their arm or leg.

General anesthesia has risks. Adding a regional anesthetic to a general anesthetic adds a second set of risks. At times regional anesthesia is indicated. I still perform peripheral nerve blocks on select patients, and I believe peripheral nerve blockade still has utility in anesthesia practice. I believe ultrasound-guided peripheral nerve blocks are indicated:

  1. If the scheduled procedure will cause significant post-operative pain.
  2. If I explain the non-zero risk of permanent nerve injury, e.g. a risk of 1 in 3000 patients, and the patient both understands this risk and consents to proceed.

Convincing a patient to agree to a peripheral nerve block by minimizing the chance of permanent nerve injury with phases such as, “nerve injury is very, very rare,” or “nerve injury is very uncommon, and it usually resolves,” is deceptive medical practice.  A 2007 survey of academic regional anesthesiologists indicated that nearly 40% of respondents did not disclose the risks of long-term and disabling neurologic injury prior to performing peripheral nerve blocks.( Brull R, et al. Disclosure of risks associated with regional anesthesia: a survey of academic regional anesthesiologists. Reg Anesth Pain Med. 2007;32:7-11)

It’s better to tell the patient the truth, and risk the following dialogue:

Anesthesiologist: “The risk of permanent nerve injury after this nerve block is very low, but it’s not zero. A ballpark incidence of the chance of permanent nerve injury to your arm (or leg) is one patient in 3,000.”

It’s your duty to explain the risks, the benefits, and the alternatives. In Hardman’s article, the author states that he circles the words “nerve injury” on the anesthesia consent for peripheral nerve block, and he has the patient write their initials next to it, to document that they have read it and understand the risks.

THE ANESTHESIA CONSULTANT

Greetings. My name is Dr. Richard Novak, the author of About The Anesthesia Consultant. The Anesthesia Consultant exists to increase your knowledge about anesthesia and the practice of medicine before, during, and after surgery. The Anesthesia Consultant is designed to inform and entertain both laypeople and medical specialists, and provides answers not found in traditional textbooks.

dscn0244

I’m a Stanford-trained physician, double-boarded in internal medicine and anesthesiology, and I’ve personally anesthetized over 25,000 patients over 34+ years. I’m currently an Adjunct Clinical Professor in the Stanford Department of Anesthesiology, Perioperative and Pain Medicine.

I’ve learned a lot over these years, and my intent is to share my knowledge with my readers, who include anesthesia professionals and lay people. This anesthesia blog contains more than 180 distinct pages and posts, all written by me. About half the columns are directed to the general public, so that they can understand anesthesia practice and the life of an anesthesia professional. The other half are detailed, well-referenced articles aimed at physician anesthesiologists, nurse anesthetists, and anesthesia assistants the world over.

I began my writing career in 2001, when I was the Deputy Chief of Anesthesia at Stanford University Hospital. Stanford is a mixed hospital, with both full time faculty and private practice faculty. I have been in the private practice of anesthesia since 1986, and my viewpoints are unique because very few private practice physician anesthesiologists have worked in a major university hospital for over thirty years.

Private practice anesthesia differs from academic anesthesia in important ways, and I began writing monthly Deputy Chief Columns in the Stanford Anesthesiology Department newsletter in 2001, to articulate these differences.

Once the total number of columns exceeded sixty, I created The Anesthesia Consultant website in 2010 to share my writing with readers outside Stanford. I continue to write 1 – 1 columns per month, in addition to maintaining a full time job as a clinical anesthesiologist.

In 2018, The Anesthesia Consultant was rated the #7 anesthesia blog in the world by Feedspot.

All expert witness testimony follows the Guidelines For ExpertWitness Qualifications and Testimony, as set forth by American Society of Anesthesiologists:

GUIDELINES FOR EXPERT WITNESS QUALIFICATIONS AND TESTIMONY (Approved by the ASA House of Delegates on October 15, 2003, and last amended on October 22, 2008) PREAMBLE The integrity of the litigation process in the United States depends in part on the honest, unbiased, responsible testimony of expert witnesses. Such testimony serves to clarify and explain technical concepts and to articulate professional standards of care. The ASA supports the concept that such expert testimony by anesthesiologists should be readily available, objective and unbiased. To limit uninformed and possibly misleading testimony, experts should be qualified for their role and should follow a clear and consistent set of ethical guidelines. A. EXPERT WITNESS QUALIFICATIONS 1. The physician (expert witness) should have a current, valid and unrestricted license to practice medicine. 2. The physician should be board certified in anesthesiology or hold an equivalent specialist qualification. 3. The physician should have been actively involved in the clinical practice of anesthesiology at the time of the event. B. EXPERT WITNESS ETHICAL GUIDELINES 1. The physician’s review of the medical facts should be truthful, thorough and impartial and should not exclude any relevant information to create a view favoring either the plaintiff or the defendant. The ultimate test for accuracy and impartiality is a willingness to prepare testimony that could be presented unchanged for use by either the plaintiff or defendant. 2. The physician’s testimony should reflect an evaluation of performance in light of generally accepted standards, reflected in relevant literature, neither condemning performance that clearly falls within generally accepted practice standards nor endorsing or condoning performance that clearly falls outside accepted medical practice. 3. The physician should make a clear distinction between medical malpractice and adverse outcomes not necessarily related to negligent practice. 4. The physician should make every effort to assess the relationship of the alleged substandard practice to the patient’s outcome. Deviation from a practice standard is not always causally related to a poor outcome. 5. The physician’s fee for expert testimony should relate to the time spent and in no circumstances should be contingent upon outcome of the claim. 6. The physician should be willing to submit such testimony for peer review.

FIVE MINUTES . . . TO AVOID ANOXIC BRAIN INJURY

Anoxic brain injury. These three words make any anesthesiologist cringe. In layman’s terms, anoxic brain injury, or anoxic encephalopathy, means “the brain is deprived of oxygen.”

Five minutes stopwatch

080116_fb-blog_1-5-c_2

In an anesthetic disaster the brain can be deprived of oxygen. Without oxygen, brain cells die, and once they die they do not regenerate. If something dire goes wrong during anesthesia and surgery and the flow of oxygen to the brain is cut off, an anesthesia practitioner has about five minutes to diagnose the cause of the problem and treat it. Some brain cells start dying within five minutes after the oxygen supply disappears, and brain hypoxia can rapidly cause severe brain damage or death. (1,2)

In malpractice cases I’ve consulted on, a five-minute window is an accepted duration for low blood oxygen levels to cause permanent brain damage.

The good news is that catastrophic events causing sudden drops in oxygen levels are very rare during anesthesia. I’ve reviewed the risks of anesthesia in the 21st Century in a previous column, which I refer you to.

Miller’s Anesthesia is the premier textbook in anesthesiology. I respect Miller’s Anesthesia as an outstanding reference, but a keyword search for “anoxic encephalopathy” in Miller’s Anesthesia only links to two chapters: one on temperature regulation, and second on pediatric intensive care. The topic of anoxic encephalopathy as related to anesthesia disasters and brain death—a issue that can ruin both a patient’s life and an anesthesiologist’s career—is not specifically covered in Miller’s Anesthesia.

Anesthesiologists are human, and human error is known to seep into anesthesia care. Miller’s Anesthesia, Chapter 7 on Human Performance and Patient Safety,3 makes several statements pertinent to human error:

“. . . anesthesia professionals themselves, both as a profession and as individuals, have strengths and vulnerabilities pertaining to their work environment. The performance of human beings is incredibly flexible and powerful in some aspects but very limited in others. Humans are vulnerable to distractions, biases, and errors.”  

“The stakes are high because even for elective surgery in healthy patients, there is an ever-present and very real risk of injury, brain damage, or even death. A catastrophe is often the end result of many pathways that begin with seemingly innocuous triggering events. . . .”

“Because more than 70% of all errors in medicine can be attributed to problems with human factors rather than problems with knowledge or practical skills, the impact of human factors cannot be overestimated.

My impression, based on 34 years in an anesthesia career, is that some anesthesia practitioners perform better under pressure. Just like Joe Montana had the knack for doing the right thing on a football field when the pressure was on, and just like Sully (Chesley Sullenberger) made correct decisions when the jet engines of US Airways Flight 1549 were knocked out by collisions with birds shortly after takeoff, some anesthesia practitioners perform well under intense pressure . . . and some don’t.

Let me present two examples, inspired by real cases, of relatively healthy young patients who had unexpected hypoxic (low oxygen) episodes. These patients had drastically different outcomes due to different anesthetic care:

CASE 1.

A 40-year-old male presented for outpatient septoplasty surgery. His past medical history was positive for obesity (weight=100 kg with a BMI=32) and hypertension. His preoperative vital signs were normal with an oxygen saturation of 98%.

Anesthesia was induced with propofol 250 mg, fentanyl 100 micrograms, and rocuronium 50 mg IV. An endotracheal tube was easily placed, and breath sounds were equal bilaterally. Anesthesia was maintained with oxygen, nitrous oxide, and sevoflurane 1.5%, and incremental doses of 50 micrograms of fentanyl.

The surgery concluded 2 hours later, and the nitrous oxide and sevoflurane were discontinued. The patient began to cough, and reached up to try to pull out his endotracheal tube. The anesthesiologist decided to extubate the trachea. After extubation the patient was making respiratory efforts, but no airflow was noted. A jaw thrust attempt to break suspected laryngospasm was ineffective. The oxygen saturation dropped to 78%.

  • Succinylcholine 40 mg was administered. There was no improvement in the oxygenation or airway.
  • Two minutes later a second dose of succinylcholine 60 mg was administered. There was continued inability to move oxygen.
  • Two minutes later, a #4 LMA was placed, with continued inability to move oxygen.
  • Two minutes later the anesthesiologist attempted to reintubate the trachea. The first attempt was unsuccessful due to poor visibility. The oxygen saturation dropped to 50%.
  • Seven minutes after the initial oxygen desaturation to 78%, a second laryngoscopy using a GlideScope was successful, and a 7.0 ET tube was placed. Copious secretions were suctioned out of the ET tube. Ventilation remained difficult and peak inspiration pressures were high. The patient continued to be hypoxic. The patient’s ECG deteriorated into pulseless electrical activity (PEA), and chest compressions were initiated. Epinephrine 1 mg was administered IV twice, the peripheral pulses returned, and chest compressions were stopped.
  • Twenty minutes after the oxygen desaturation to 78%, the oxygen saturation finally rose to 94%. A chest x-ray showed pulmonary edema. The diagnosis was laryngospasm leading to negative pressure pulmonary edema. Furosemide 20 mg was administered IV. The patient remained on a ventilator in the ICU for seven days, at which time he was declared brain dead.

CASE 2.

A 30-year-old male was scheduled for maxillary and mandibular osteotomies for obstructive sleep apnea. He was otherwise healthy. He weighed 80 kg and had a BMI=26. His preoperative vital signs were normal.

Anesthesia was induced with propofol 250 mg and rocuronium 50 IV, and a right cuffed nasal endotracheal tube was placed. Breath sounds were bilateral and equal. Anesthesia was maintained with sevoflurane 1.5%, nitrous oxide 50%, propofol 50 mcg/kg/hr, and incremental doses of 50 mcg fentanyl. The surgery concluded 4 hours later. The surgeons wired the upper and lower teeth together. The propofol, sevoflurane, and nitrous oxide were discontinued.

The patient opened his eyes ten minutes later, and responded appropriately to conversation. The endotracheal tube was removed, and the patient’s airway was patent. He was moved to the gurney, the back of the gurney was elevated 30 degrees, and a non-rebreather mask with a 10 liters/minute flow rate of oxygen was strapped over his face. The anesthesiologist then transported the patient down the hallway to the PACU. En route the patient became more somnolent and developed upper airway obstruction resistant to jaw thrust maneuvers.

  • On arrival at the PACU the patient was nonresponsive, and his initial oxygen saturation was 75%. The anesthesiologist began mask ventilation via an Ambu bag, and the oxygen saturation rose to 90%. The patient was making ventilatory efforts without significant air movement.
  • The wires fixating the maxilla and mandible together were severed with a wire cutter.
  • The anesthesiologist attempted laryngoscopy with a Miller 2 blade, and was unable to visualize the larynx because of frothing fluid bubbling in the oropharynx. A presumptive diagnosis of negative pressure pulmonary edema was made, and a GlideScope was called for. The oxygen saturation was 88%.
  • After suctioning the frothy fluid which filled the oropharynx, a second laryngoscopy attempt with the GlideScope yielded successful placement of a 7.0 oral endotracheal tube. Pulmonary edema fluid was suctioned from the lumen of the endotracheal tube, and furosemide 20 mg was injected IV. The oxygen saturation rose to 98% on 100% oxygen.

The duration of time from when the patient’s oxygen level was discovered to be 75% until his oxygen level rose above 90% was two minutes. The duration of time from when the patient’s oxygen level was discovered to be 75% until the trachea was successfully reintubated was four minutes.

The patient remained intubated in the ICU for two nights, with diagnoses of upper airway edema post maxillary-mandibular osteotomies and negative pressure pulmonary edema. He was extubated on post-op day #3, when he successfully passed a cuff-leak test. His oxygen saturations were normal and his brain was undamaged. He walked out the hospital alive and well.

Case #1 and Case #2 were similar in that both patients were young relatively healthy men having head and neck surgery. The expected risk of serious complication for each procedure was low. The expected risk of death, or of brain death, was extremely small. Yet one man died and the other survived.

Why?

In Case #1, a case study based on a closed claim malpractice settlement, the delays in anesthesia care led to prolonged low oxygen levels, and these prolonged low oxygen levels caused anoxic brain damage. The deviations from the standard of care included:

  1. The patient was extubated too early, at a time when he was still partially anesthetized, in a transitional phase of anesthesia, and not yet awake. The safest technique for extubation is awake extubation, when the patient is an awake state of eye opening and obeying commands. Per the Difficult Airway Society Guidelines for the Management of Tracheal Extubation, an awake intubation is when “the patient’s eyes are open and the patient is responsive to commands.”4 This patient had head and neck surgery, and was at risk for post-operative airway problems. Extubating before the patient opened his eyes and obeyed verbal commands was a deviation from the standard of care.
  2. Once the patient developed post-extubation laryngospasm, the standard of care was for the anesthesiologist to act immediately to relieve airway obstruction and correct hypoxemia. Laryngospasm can lead to hypoxia, as it did in this case. The order of treatment is A-B-C, or Airway–Breathing–Circulation. When the immediate application of jaw thrust and continuous positive airway pressure via facemask was unsuccessful, and the oxygen saturation dropped into the 70’s, the standard of care was to immediately paralyze the patient with an intubating dose of succinylcholine (1 mg/kg IV) and to reinsert an endotracheal tube. Per Difficult Airway Society Guidelines for the Management of Tracheal Extubation, “If laryngospasm persists and/or oxygen saturation is falling: (administer) succinylcholine 1 mg/kg intravenously. Worsening hypoxia in the face of continuing severe laryngospasm with total cord closure . . . requires immediate treatment with intravenous succinylcholine. The rational for 1 mg/kg is to provide cord relaxation, permitting ventilation, re-oxygenation and intubation should it be necessary.”4 The entire time from the onset of laryngospasm to the successful control of the airway and ventilation of the lungs in Case #1 exceeded 20 minutes.

When a bad outcome like this occurs in a hospital or surgery center, a facility’s Quality Assurance Committee examines the details of the case—not to assign blame—but to identify flaws in patient care systems which must be improved in the future.

When a patient’s family hires a lawyer to investigate a bad outcome, the same analysis of the medical record and the medical details occurs, but the stakes are different. Physicians and facilities carry malpractice insurance with limits in the millions of dollars. If a physician or a facility is found to have performed below the standard of care, and if that negligent performance is found to have caused patient damage, they may well lose a malpractice settlement. The minute-by-minute pulse oximetry data will be scrutinized during any ensuing malpractice trial or deposition, with an aim to document how many minutes the oxygen saturation was critically low. A time frame of five minutes or greater of hypoxia in the medical record can be damning for the anesthesiologist’s case.

In the Miller’s Anesthesia chapter titled Human Performance and Patient Safety, Drs. Rall and Gaba describe 15 Key Points of Crisis Resource Management (CRM).3 Highlights of the Key Points include:

  • CRM Key Point 2. Anticipate and Plan. “Anesthesia professionals must consider the requirements of a case in advance and plan for the key milestone. They must imagine what could go wrong and plan ahead for each possible difficulty. Savvy anesthesia professionals expect the unexpected, and when it does strike, they then anticipate what could happen next and prepare for the worst.”
  • CRM Key Point 3. Call for Help Early.
  • CRM Key Point 4. Exercise Leadership and Followership With Assertiveness. “A team needs a leader. Someone has to take command, distribute tasks, collect information, and make key decisions. . . . Followers are key members of the team who listen to what the team leader says and do what is needed.”
  • CRM Key Point 8. Use All Available Information. “Information sources include those immediately at hand (the patient, monitors, the anesthesia record), secondary sources such as the patient’s chart, and external sources such as cognitive aids (see later) or even the Internet.”
  • CRM Key Point 11. Use Cognitive Aids. “Cognitive aids—such as checklists, handbooks, calculators, and advice hotlines—come in different forms but serve similar functions. They make knowledge “explicit” and “in the world” rather than only being implicit, in someone’s brain.” An example cognitive aid is the Stanford Emergency Manual, which I recommend.5

Dr. David Gaba, one of the authors of this chapter, is a longtime friend of mine and a pioneer in the fields of anesthesia simulator design and crisis management. I respect this list of 15 CRM Key Points, but I also know that when the clock is ticking on those five minutes of patient hypoxia, there is no time to think through 15 items. There is no time for any wasted effort or motions. The anesthesia provider must captain the ship and restore oxygenation without delay. The anesthesia provider needs a plan embedded in his or her brainstem that allows them to keep the patient safe.

Based on my experience as both a practicing anesthesiologist for over 30 years and an expert witness for over 15 years, when your patient’s oxygen level drops acutely, these are the things you need to DO:

  1. First off, turn your oxygen supply to 100% oxygen. Turn off all nitrous oxide or air input.
  2. Call for help.
  3. Think A-B-C, or Airway-Breathing-Circulation, in that order.
  4. Examine the patient, particularly their airway and lungs.
  5. If the patient is not already intubated, and you cannot mask ventilate the patient to a safe oxygen level, intubate the trachea immediately to deliver 100% oxygen via controlled ventilation. Use succinylcholine, the fastest emergency paralytic drug.
  6. If you cannot intubate the patient with a traditional Miller 2 or Mac 3 blade, request a GlideScope videoscope ASAP. (Have the American Society of Anesthesiologists Difficult Airway Algorithm committed to memory.)
  7. Have the Stanford Emergency Manual5 in your operating room suite, and ask a registered nurse to recite the Cognitive Aid Checklist for HYPOXEMIA to you, to make sure you haven’t missed something.
  8. If the patient is still not improving, reaffirm your assessments of A-B-C. Fix the Airway, fix the B, then fix the Circulation.
  9. Remember: ACLS (Acute Cardiac Life Support) is important, but ACLS is C, and if A and B are faulty, the cardiac care of ACLS will not save the brain.

Other advice to anesthesiologists:

  • Before a hypoxic emergency occurs in your practice, do yourself and your patients a favor by passing the American Board of Anesthesiologists oral board examination. The time spent studying for the oral boards will make you a safer and smarter anesthesiologist who is better prepared to handle emergency situations. A study in the journal Anesthesiology showed rates for death and failure to rescue from crises were greater when anesthesia care was delivered by non-board certified midcareer anesthesiologists.6 In the Stanford Department of Anesthesiology, Perioperative and Pain Medicine, we administer mock oral board examinations to the residents and fellows twice a year. Presenting an examinee with a sudden hypoxic episode is a common occurrence during the exam. If you can think well in a room in front of two examiners, you are more likely to think well in a true hypoxemic emergency when your patient’s life is at stake.
  • A second tip: If you have access to anesthesia simulator sessions, enroll yourself.

What if you’re a patient reading this? What if you’re contemplating surgery? How can you optimize your chances to avoid an anesthetic disaster?

I offer these suggestions:

  • Choose to have your surgery at a facility that is staffed with American Board of Anesthesiology board-certified physician anesthesiologists.
  • Ask a knowledgeable medical professional to recommend a specific anesthesiologist at your facility, and request that specific anesthesiologist for your care.
  • Inquire about who would manage your crisis if you have one during or after your surgery. Will your anesthesia professional be a physician anesthesiologist, a Certified Registered Nurse Anesthetist (CRNA), or an anesthesia care team made up of both? If an anesthesia care team is attending to you, how many rooms is each physician anesthesiologist supervising? How far away or how many minutes away will your physician anesthesiologist be while you are asleep?
  • In the future, quality of care data will be available on facilities and physicians, including anesthesiologists. These metrics will allow patients to compare facilities and physicians. Do your homework with whatever data is publicized. Research the facility you are about to be anesthetized in.
  • If you’re a higher risk patient, i.e. you have: significant obesity, obstructive sleep apnea, heart problems, breathing problems, age > 65, or you’re having regular dialysis, emergency surgery, abdominal surgery, chest surgery, major vascular surgery, cardiac surgery, brain surgery, regular dialysis, total joint replacement, or a surgery with a risk of high blood loss . . . be aware you’re at a higher risk, and ask more questions of your surgeon and your anesthesia provider.
  • If yours is an elective surgery, realize you have time to heed the advice in this column. Take your time to choose your surgeon, your facility, and your anesthesia provider if you can.

None of us, anesthesia providers or the families of patients, want to be sitting in a courtroom for a malpractice trial because there were five bad minutes without oxygen.

LETHAL EXECUTION USING FENTANYL . . . AN ANESTHESIOLOGIST’S OPINION

Lethal injection using fentanyl occurred for the first time in the death penalty execution of Carey Dean Moore in Nebraska August 14th, 2018.

lethal-injection-0000-1503512440

Per CBS News, “The Nebraska drug protocol called for an initial IV dose of diazepam, commonly known as Valium, to render the inmate unconscious, followed by the powerful synthetic opioid fentanyl, then cisatracurium besylate to induce paralysis and stop the inmate from breathing and potassium chloride to stop the heart.

Diazepam and cisatracurium also had never been used in executions before.”

From an anesthesiologist’s point of view:

  1. Valium (diazepam), an antianxiety drug, is seldom used in current surgical anesthesia practice, as it has been replaced by Versed (midazolam), which has a faster onset and causes less stinging on intravenous injection.
  2. Fentanyl, a powerful morphine-type narcotic, given in very high doses, brings on sedation, respiratory depression, and unconsciousness. The combination of Valium and high doses of fentanyl (typically 100 micrograms per kilogram) was the standard anesthetic used for open heart surgery in the 1980s. High doses of fentanyl can cause chest wall rigidity, which would add to any agonal respiratory efforts during a lethal injection, hence the necessity of a muscle relaxant (see below).
  3. Cisatracurium, a muscle relaxant or paralyzing drug, blocks all muscle movement and breathing. The paralyzing drug is used to both stop respiration and to eliminated any writhing and agonal movements during the dying movements.
  4. Potassium chloride, in high concentrations, causes the heart to fibrillate and cease beating.

Beginning in the 1970s, initial lethal injection recipes in the United States included 1) sodium thiopental (a barbiturate) to induce sleep, 2) pancuronium (a muscle relaxant) to paralyze the individual, and 3) potassium chloride to fibrillate the heart. In the 1970s-1990s, thiopental and pancuronium were commonly used anesthetic drugs. (In recent decades, propofol has replaced thiopental as the hypnotic of choice for general anesthesia for surgery, and the drugs rocuronium and vecuronium have replaced pancuronium as muscle relaxants for surgery.)

The European Union banned the export of thiopental for lethal injection in 2011, and a search for available alternate sedatives and intravenous anesthetics ensued. By 2016, more than twenty American and European pharmaceutical manufacturers had blocked the sale of their drugs for use in lethal injections, effectively making most FDA-approved unavailable for any potential lethal execution drug.1

This use of fentanyl, diazepam, and cisatracurium in Nebraska is the latest chapter in the recipe for lethal injection story. Stay tuned to see whether the manufacturers of these drugs choose to ban their sale for use in capital punishment.

ANESTHETIC RISKS IN CHILDREN

What are the anesthetic risks for children? What should you do if your 2-year-old son or daughter requires surgery and anesthesia? Should you consent to proceed? Should you wait until he or she is 3 years old?

The answer to all these questions is: “It depends.”

am_150605_child_anesthesia_800x600

Let’s look at recommendations as they exist in 2018.

On December 14, 2016, the United States Food and Drug Administration (FDA) issued a Drug Safety Communication Drug Safety Communication Warning that general anesthesia and sedation drugs used in children less than 3 years of age who were undergoing anesthesia for more than 3 hours, or repeated use of anesthetics, “may affect the development of children’s brains.”

The text of this December 2016 FDA statement reads:

The U.S. Food and Drug Administration (FDA) is warning that repeated or lengthy use of general anesthetic and sedation drugs during surgeries or procedures in children younger than 3 years or in pregnant women during their third trimester may affect the development of children’s brains. . . . Consistent with animal studies, recent human studies suggest that a single, relatively short exposure to general anesthetic and sedation drugs in infants or toddlers is unlikely to have negative effects on behavior or learning. However, further research is needed to fully characterize how early life anesthetic exposure affects children’s brain development. . . . Health care professionals should balance the benefits of appropriate anesthesia in young children and pregnant women against the potential risks, especially for procedures that may last longer than 3 hours or if multiple procedures are required in children under 3 years. Discuss with parents, caregivers, and pregnant women the benefits, risks, and appropriate timing of surgery or procedures requiring anesthetic and sedation drugs.”

This FDA warning resulted in a labeling change for these 11 common general anesthetics drugs and sedative agents:

  • Propofol
  • Sevoflurane
  • Midazolam
  • Isoflurane
  • Desflurane
  • Halothane
  • Pentobarbital
  • Etomidate
  • Ketamine
  • Lorazepam
  • Methohexital

Of these, sevoflurane and propofol are mainstay drugs used in pediatric anesthetics. Anesthesia for infants and children is most frequently initiated with an inhalation induction of sevoflurane vapor, because most infants and children do not have an IV line prior to induction. The primary intravenous hypnotic drug for children is propofol.

Because of this FDA statement, the propofol package insert warning label now reads:

Pediatric Use; ANIMAL TOXICOLOGY AND/OR PHARMACOLOGY). Some published studies in children suggest that similar deficits may occur after repeated or prolonged exposures to anesthetic agents early in life and may result in adverse cognitive or behavioral effects. These studies have substantial limitations, and it is not clear if the observed effects are due to the anesthetic/sedation drug administration or other factors such as the surgery or underlying illness. Anesthetic and sedation drugs are a necessary part of the care of children needing surgery, other procedures, or tests that cannot be delayed, and no specific medications have been shown to be safer than any other. Decisions regarding the timing of any elective procedures requiring anesthesia should take into consideration the benefits of the procedure weighed against the potential risks.”

For sevoflurane, the package insert warning label now reads:

Repeated or lengthy use of general anesthetic and sedation drugs during surgeries or procedures in neonates, infants, and children younger than 3 years, including in utero exposure during the third trimester, may have negative effects on brain development. Consider the benefits of appropriate anesthesia in young children against the potential risks, especially for procedures that may last more than 3 hours or if multiple procedures are required during the first 3 years of life. It may be appropriate to delay certain procedures if doing so will not jeopardize the health of the child. No specific anesthetic or sedation drug has been shown to be safer than another. Human studies suggest that a single short exposure to a general anesthetic in young pediatric patients is unlikely to have negative effects on behavior and learning; however, further research is needed to fully characterize how anesthetic exposure affects brain development.

There are no real alternatives to these 11 general anesthetic drugs regarding pediatric anesthesia. Dexmedetomidine and narcotics are not on the FDA list, but dexmedetomidine and narcotics are not sufficient to provide general anesthesia by themselves.

What does this mean to physicians and parents regarding anesthetics on children under the age of 3 years?

The most common indications for infants and toddlers to be placed under general anesthesia are for short procedures such as ear tubes for chronic ear infections, hernia repair, or removal of the adenoids. At times infants or toddlers require general anesthesia or sedation so they will stay still during a procedure, such as when they need an MRI or a CT scan.

There are an estimated 1.5 -2 million children under 3 years of age who undergo anesthesia annually in the United States. Prior to the FDA statement, Texas Children’s Hospital performed more than 43,000 cases each year. Approximately 13,000 of these cases involved patients under 3 years of age, and more than 11,000 of these anesthetics lasted more than 3 hours. Nearly all of the prolonged anesthetics were for serious congenital conditions for which treatment could not be delayed until the patient reached 3 years of age. Because of the FDA warning, the hospital adopted the warning’s recommendation that a discussion occur among parents, surgeons and other physicians, and anesthesiologists regarding the duration of anesthesia, any plan for multiple general anesthetics for multiple procedures, and the possibility that the procedure could be delayed until after 3 years of age.1

Dr. Constance Houck, chair of the American Academy of Pediatrics’ Surgical Advisory Panel and an Associate Professor of Anesthesia at Harvard Medical School said, “two recently published studies examining short-term anesthesia exposure for hernia repair did not show neurobehavioral differences between those who had received a general anesthetic and those who had not. . . . Most surgeries are less than one hour, but some infants and children with significant congenital defects require more prolonged surgery. . . Examples would include such defects as cleft lip and palate and malformations of the urinary or gastrointestinal tract.” Postponing major reconstructive surgery until children are older is generally not an option. “There is no evidence to suggest that short procedures should be postponed, but parents should always discuss with their child’s pediatrician and surgeon the risks and benefits of timing of procedures.2

The American Society of Anesthesiologists response to the FDA statement read: “the accumulated human data suggest that one brief anesthetic is not associated with cognitive or behavioral abnormalities in children. Most but not all studies in children do however suggest an association between repeated and or prolonged exposure and subsequent difficulties with learning or behavior.”3

In addition to the FDA drug recommendations, there are well documented surgical concerns with operating on children under age 3. For example, the recommendations for pediatric tonsillectomy are to delay until age 3, based on a high degree of evidence for increased respiratory complications at ages younger than 3.4

An overriding important consideration regarding pediatric anesthetics is: Who will be doing the anesthesia? It’s important to inquire regarding the experience and training of the physician anesthesiologist who is about to anesthetize your child. (See my related column Pediatric Anesthesia: Who is Anesthetizing Your Child?)

Some anesthesiologists do specialty fellowship education for one or two years in pediatric anesthesia, usually at an academic pediatric hospital, and are therefore well-trained to attend to your child. In community hospitals, experienced physician anesthesiologists who have attended to children since their residency training commonly do pediatric anesthetics. My practice fits this model: I am not a fellowship-trained pediatric anesthesiologist, but I have anesthetized thousands of children safely over 33+ years since my Stanford residency.

Let’s return to the question of whether your 2-year-old should have anesthesia and surgery.

My family had a personal experience with this question. My oldest son fell and cracked his upper right incisor when he was 1½ years old. He had three general anesthetics in the following nine months for dental surgeries: the first surgery to place a cap on the fractured tooth, the second surgery to extract the tooth because it died, and a third surgery to place a prosthetic incisor to replace the lost tooth. These three surgeries were performed in 1998 and 1999 when my son was between 1½ and 3 years of age. He suffered no apparent developmental delays secondary to anesthesia, but in the present day, following the FDA statement, both the physicians and the parents would be unlikely to proceed with three repeated anesthetics on such a young child.

The answer for you depends on whether your child’s surgery is elective and can wait until he or she is 3 years old, whether it is a one-time surgery, whether the surgery is brief, whether it is an emergency or whether it is to remedy a congenital deformity and can not be delayed. You’ll need to have an informed consent discussion with the surgeon, the physician anesthesiologist, and perhaps your pediatrician. If your child’s surgery is a one-time anesthetic for a common short procedure such as ear ventilation tubes or an inguinal hernia repair, it’s likely that proceeding with anesthesia and surgery will be the correct answer. If the surgery is urgent or if delaying surgery will cause an adverse outcome, then proceeding with anesthesia and surgery will be the correct answer. Trust your surgeon and physician anesthesiologist as consultants, and you’ll make the correct choice.

Be reassured. The Society for Pediatric Anesthesiology states that “complications are extremely rare. In the United States, the chance (risk) of a healthy child dying or sustaining a severe injury as a result of anesthesia is less than the risk of traveling in a car.”5

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

HOW NEW IS “MODERN ANESTHESIA?”

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

THE ANESTHESIA CONSULTANT

Point/Counterpoint: How new is modern anesthesia? Are modern anesthesia techniques radically different from the methods of twenty years ago? True or false?

1990s-moodboard

 

POINT: False. Twenty-first century general anesthetics are nearly identical to the anesthetic techniques of the late 1990s. Consider this list of the most commonly administered anesthetic drugs in the United States in the present day (2018):

Medication                        Year introduced

Propofol                              1989

Sevoflurane                        1995

Nitrous oxide                     1846

Fentanyl                               1959

Versed                                   1985

Rocuronium                        1994

Succinylcholine                  1952

Zofran                                  1991

Bupivicaine                          1957

 

I review hundreds of anesthesia records each year from California and multiple other regions of America. I can attest that these nine medications are still the mainstays of most anesthetics. A typical standard general anesthetic includes Versed as an anti-anxiety premed, propofol as the hypnotic, sevoflurane +/- nitrous oxide as the maintenance vapor(s), fentanyl as the narcotic, Zofran for nausea prophylaxis, rocuronium or succinylcholine for muscle paralysis, and bupivicaine injected (usually by the surgeon) for long-lasting pain relief.

How can it be that general anesthesia has ceased to evolve? In this brave new world of the Internet, iPhones, iPads, and personal computers, how could anesthesiology have stalled out with 20th-century pharmacology? My colleague Donald Stanski, MD PhD, former Chairman of Anesthesiology at Stanford and now an executive in pharmacology business, explained it to me this way: The existing anesthesia drugs are cheap and work well. The cost of research and development for each new anesthesia drug is prohibitively expensive, and for pharmaceutical companies there is no certainty that any new anesthesia drug would control a sufficient market share to make a profit.

I believe we would benefit from a new narcotic drug that would promise less side effects than the fentanyl/morphine analogues, i.e. less respiratory depression, nausea, and sedation. I believe we would benefit from a new ultra-short onset paralyzing drug without the side effects of succinylcholine, i.e. without the risks of muscle pain, hyperkalemic arrests, triggering of malignant hyperthermia, increased intracranial and intraocular pressure, or bradycardia. Someone may discover these products someday, but for the present time the older drugs enjoy the market share.

What about regional anesthesia? When a patient needs a spinal anesthetic, the recipe of bupivicaine +/- morphine is unchanged from the 1990s. When a patient needs an epidural for surgery, the recipe of bupivicaine or lidocaine +/- narcotic is unchanged from the 1990s.

What about monitors of vital signs? The standard monitoring devices of pulse oximetry, end-tidal CO2 monitoring, and other essential anesthesia vital sign monitors were developed and in use by the 1990s. I can think of no specific reason why a general anesthetic administered in 2018 would be safer than a general anesthetic administered in the 1990s.

 

COUNTERPOINT: True. Anesthesia in 2018 is markedly different from anesthesia in the 1990s. Most of the drugs in use haven’t changed, but current-day anesthesia providers practice in a cockpit surrounded by computers. Each operating room anesthesia location is the epicenter of computerized medical record-keeping machines, computerized Pyxis-style drug storage systems, computerized labeling machines, and bar-code reading billing machines. If you don’t understand how to command these high-tech devices, you’ll be unable to initiate an anesthetic at a university hospital. The adage that “the patient comes first” is sometimes lost in an array of LED displays, passwords, and keyboards.

There have been other significant changes in anesthesia practice since the year 2000:

  • The most significant advance is the video laryngoscope, a vital tool for intubating difficult airways, which has facilitated endotracheal intubation in thousands of patients where 20th-century rigid laryngoscope blades were not effective.
  • Ropivicaine was released in the year 2000, and has the distinct advantage of long-lasting local anesthetic nerve blockade with less motor block than bupivicaine.
  • Sugammadex is a remarkable advance, allowing for the reliable reversal of neuromuscular paralysis in only seconds. Sugammadex is the single most important new medication in the toolbox of the 21st-century anesthesiologist.
  • Ultrasound-guided regional anesthesia was developed in 1994, but became popular in the past ten years. Administering local anesthetic injections adjacent to major nerves grants non-narcotic pain relief to thousands of patients following orthopedic surgeries.
  • Acute pain services utilize nerve blocks and other adjuncts to relieve post-operative discomfort. Pain service teams were available only in primitive forms in the 1990s. In fact, at Stanford we changed our name from the “Department of Anesthesiology” to the “Department of Anesthesiology, Perioperative and Pain Medicine” since the turn of the millennium.

 

In closing:

At a wedding a bride is advised to wear something old, something new, something borrowed, and something blue.

In the world of anesthesia we use some things old, some things new, nothing borrowed, and . . . we make sure our patients never turn blue.   🙂

THE JOY OF BEING A DOCTOR

THE ANESTHESIA CONSULTANT

My greatest joy of being a doctor comes immediately after the conclusion of a pediatric anesthetic.

maxresdefault

I stay with the child until the anesthetic depth has dissipated, the breathing tube is removed, and the child is awake and safe with the recovery room nurse in the Post Anesthesia Care Unit. At that point I walk out to the waiting room to find the parents so I bring them back to see their child. I invariably have a bounce to my step, and I’m a bit choked up with anticipation. I’ve done this enough times to know what to expect. The mother and father are waiting with wide eyes and worried looks on their faces. I give them a reassuring smile and my first words are, “Everything went perfectly. Your son (or daughter) is safe. Follow me.” The three of us return to the bedside in the recovery room, where the mother and child reunion occurs (cue up the Paul Simon soundtrack). The parents fawn over their child, the child reaches out his or her arms, the relief is palpable, and I’m proud to have contributed to the positive outcome.

Why go to medical school? Bright, hard-working college students have choices to make. Many ambitious young people wonder if they should apply to medical school. It’s difficult to get into med school, the journey is long (four years of medical school followed by three to seven years of residency), and the tuition can be high.

Why go to medical school? The daughter of one of my friends is an undergraduate business school student, and her last summer internship was with Proctor and Gamble working in the sales and marketing force selling Clorox. Selling bleach is a career choice radically different from going to medical school.

Do you want to sell bleach, or do you want to help people? The answer to “Why do you want to go to medical school?” is almost that simple. So many jobs in America are related to selling some product, some service, or some commodity. Becoming a physician is about helping people, and it’s also about making your own life have a greater purpose.

“Why do you want to be a doctor?” is the first question asked at most medical school interviews. Answers vary. Why do young men and women choose to become doctors nowadays? One guiding factor might be economics. The average salary for a physician in the United States is in excess of $250,000. To a 22-year-old, that high salary is alluring. Non-medical students who pursue careers in teaching, engineering, or business will start at lower annual salaries, but the future income of a physician is balanced against the deferred gratification of the years involved in their education. The student must pay for four years of medical school tuition and living expenses, and then work for meager wages for 3-7 years afterwards as a resident. The medical student delays the onset of their “real world” employment until age 30-32.

Non-medical students who go to work straight out of college at age 22 may already have families, mortgages, multiple cars, and perhaps a vacation home, while the 32-year-old physician has an 80-hour-a-week job, $250,000 of student loans, and the obligation to take care of sick patients at 3 a.m. It’s not an easy life, it’s not all fun, and most doctors wonder at one time or another whether they made the right choice. Making a lot of money is not the right answer to the question of why you want to go to medical school.

So why do we go to medical school? Young men and women who have a physician parent are in the best position to reply from the heart—they’re aware that their parent works long hours, reads incessantly to stay well informed, and gets out of bed in the middle of the night to handle emergencies. A doctor’s son or daughter has heard all the good and bad stories that describe a physician’s lifestyle. But most college students don’t have a doctor for a parent, and most college students have a little idea what the lifestyle of a physician would feel like. My father was a welder. I had no family experience to guide my career choice. For students like me, without a physician parent, it’s important to work medical volunteer jobs and/or research jobs to test the waters before applying to medical school, to decide whether the life of a doctor would appeal to them.

Why go to medical school? Each new patient I meet treats me with respect—a respect I don’t get if I’m outside of the hospital walking down the street or shopping at a grocery store. Years ago I shared this impression with my wife, and she said, “Of course your patients treat you with respect. You’re about to take their lives into your hands. They’re nervous, they’re scared, and the last thing they want to do is to get you in a bad mood!” This may be true, but the respect your patients give you is bona fide, and it’s a feeling few other jobs can offer.

Why go to medical school? I don’t think you’ll ever get equivalent joy out of selling bleach (or some other commodity) that you’ll gain helping other human beings with their health problems. Medicine is a profession. A career in medicine is an opportunity to entwine your work life with other people’s lives in a meaningful and remarkable way. You might make more money as a CEO or a venture capitalist, but few other jobs bring the potential to change lives for the better to the degree that being a physician does.

When you go to your medical school interview and the professor asks you “Why do you want to be a doctor,” the answer from your heart must be five words long:

“I want to help people.”

Your reward for becoming a doctor will arrive years later, when you feel what I feel when I reunite parents with their child after surgery. You’ll feel the joy and satisfaction of a purposeful life.

 

P.S. In 2012 the journal Anesthesiology published my poem “The Metronome,” which describes a scene from my life as a pediatric anesthesiologist:

 

The Metronome

 

To Jacob’s mother I say,

“The risk of anything serious going wrong…”

She shakes her head, a metronome ticking without sound.

“with Jacob’s heart, lungs, or brain…”

Her lips pucker, proving me wrong.

“isn’t zero, but it’s very, very close to zero…”

Her eyes dart past me, to a future of ice cream and laughter.

“but I’ll be right there with him every second.”

The metronome stops, replaced by a single nod of assent.

She hands her only son to me.

 

An hour later, she stands alone,

Pacing like a Palace guard.

Her pupils wild. Lower lip dancing.

The surgery is over.

Her eyebrows ascend in a hopeful plea.

I touch her hand. Five icicles.

I say, “Everything went perfectly. You can see Jacob now.”

The storm lifts. She is ten years younger.

Her joy contagious as a smile.

The metronome beat true.

FENTANYL AND THE OPIOID CRISIS: AN ANESTHESIOLOGIST’S PERSPECTIVE

Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

The United States is in the midst of an opioid epidemic. The crisis consists of two separate threats. One is the increased presence of powerful illicit street drugs such as fentanyl. The second threat is the increasing use of oral prescription painkillers like Oxycontin, Percocet, and Vicodin. This column addresses fentanyl—its medical aspects and the on-the-street abuses of this powerful narcotic.

0641-6028-25

MEDICAL USE OF FENTANYL

I’ve administered fentanyl to over 20,000 patients in my career, and can vouch for the medical utility and import of this drug. Fentanyl is the most commonly administered narcotic during surgery in the United States. If you’ve had a surgical anesthetic, or even a colonoscopy, you’ve likely received fentanyl with few ill effects. Fentanyl is an essential ingredient in the pharmaceutical armamentarium of acute care medicine in hospitals, surgery centers, intensive care units, and emergency rooms throughout the United States. On the streets, fentanyl is killing people. In our hospitals and surgery centers, fentanyl is a useful adjunct as omnipresent as Tylenol.

Fentanyl was first synthesized by Dr. Paul Janssen of Janssen Pharmaceuticals in the 1960s, and was then introduced into anesthetic practice under the brand name Sublimaze.1 Fentanyl is a rapid-onset narcotic drug usually administered by intravenous injection. Compared to morphine, fentanyl is more lipid (fat) soluble, which means the drug crosses into the central nervous system more quickly and works faster than morphine. The termination of the effect of low doses of fentanyl results from decreased concentration, as the drug redistributes from the bloodstream to other organ tissues.

The elimination of higher doses of fentanyl from the body depends on elimination by the liver. Morphine, Demerol, and Dilaudid are other common intravenous medical narcotics, which have slower onset and longer duration of action. When injected into an intravenous line, fentanyl reaches its peak analgesic effect in minutes, significantly faster than morphine. This quicker onset makes fentanyl an easier drug for anesthesiologists to titrate to a desired effect., which makes fentanyl superior when timing for a patient’s awakening from anesthesia. As outpatient and ambulatory surgery blossomed, a short-acting narcotic such as fentanyl, which wore off promptly, became the narcotic of choice.

The most daunting feature of fentanyl is its potency. Most drugs used by anesthesiologists are in doses of milligrams (mgs) or grams (gms). Fentanyl is approximately 100 times more potent than morphine, so a typical 5 mg (5 mg = 5000 microgram) dose of morphine is equivalent to a mere 50 microgram dose of fentanyl. A typical intravenous incremental dose of fentanyl to an adult patient is a mere 50-100 micrograms. The drug is marketed as one milliliter = 50 micrograms for this reason, so 1 – 2 milliliters is an appropriate dose. This potency and the need to be packaged in micrograms is unique to fentanyl and its analogues sufentanil and remifentanil, and requires medical personnel to become comfortable with the low ranges of the appropriate microgram doses.2

Medical fentanyl can be administered in several ways:

  • Intravenous fentanyl, as described above, is the most common medical usage of the drug.
  • Rarely, fentanyl is added to the spinal fluid as part of a spinal anesthetic block prior to surgery, or to the epidural space as part of an epidural block prior to surgery or prior to labor for childbirth.
  • Transdermal drug delivery of fentanyl via an adhesive skin patch is also possible, because of the drug’s high solubility in both water and oil, low molecular weight, high potency, and its lack of skin irritation. Fentanyl transdermal patches (Durogesic or Duragesic) are useful in chronic pain management. The patches work by slowly releasing fentanyl through the skin into the bloodstream over 48 to 72 hours, allowing for long-lasting pain management. Dosage is based on the size of the patch.
  • Oral transmucosal fentanyl citrate (OTFC) is a solid dosage form of fentanyl that consists of fentanyl incorporated into a sweetened lozenge on a stick. A commercially available fentanyl product for oral administration, the fentanyl lollipop Actiq, is an application of this technology. The lollipop provides a means by which the drug can dissolve slowly in the mouth. The lollipop is only FDA approved for providing analgesia to patients with chronic pain or cancer pain, and the fentanyl lollipop is not FDA-approved for analgesia after surgery.

Narcotics suppress pain by their action in the brain and spinal cord, but they cause their adverse side effects in multiple organ systems, including the respiratory and cardiovascular systems. The principal danger from narcotics is respiratory depression. The respiratory rate is usually markedly slowed in narcotic overdose, as excessive doses of narcotics make people stop breathing. If there’s an anesthesiologist present to support a person’s breathing, respiratory depression is not a problem. On the streets, with no medical personnel present, respiratory depression from a narcotic overdose can be fatal.

The anesthesia world is well aware of the risks of fentanyl addiction. Narcotic addiction has struck down many anesthesia providers who found themselves vulnerable to sampling the potent euphoria-inducing fentanyl doses they were administering to their patients. Stanford authors described fentanyl addiction in anesthesiologists in 1980.3 More than a dozen of my personal friends and colleagues died anesthetic drug-related addiction deaths in the 1980s and 1990s.

For some of these physicians the first sign of their addiction was death by overdose. In others the addiction was uncovered, they were sent to rehabilitation programs, and they are still alive today. Anesthesiologists graduating from narcotic rehab programs are still known to have a risk to relapse. The relapse rate for anesthesiologists after drug abuse treatment is greatest in the first 5 years and decreases as time in recovery increases. The positive news is that 89% of anesthesiologists who complete treatment and commit to aftercare remain abstinent for longer than 2 years. However, death is still the primary presenting sign of relapse in opiate-addicted anesthesiologists.

 

FENTANYL AS A STREET DRUG

The current battle against fentanyl as a street drug has little or nothing to do with American medical practice. Most of the fentanyl found on the streets is not diverted from hospitals, but rather is sourced from China and Mexico. Dealers sought a narcotic product cheaper and even stronger than heroin, and that product is fentanyl. In 2016 there were more than 60,000 fatal overdoses in America. More than half were due to opioids, and the newest and most potent street narcotic was fentanyl.

Fentanyl-related overdose deaths increased nearly 600 percent from 2014 to 2016. “If anything can be likened to a weapon of mass destruction in what it can do to a community, it’s fentanyl,” said Michael Ferguson, a special agent in charge of the Drug Enforcement Administration’s New England division. “It’s manufactured death.” Illicit fentanyl is imported directly from China or Mexico, where the drug is manufactured. Dealers then mix the powder into other drugs, making for imprecise potency in sometimes-lethal doses.4 The IV street drug fentanyl is believed to be manufactured in China or Mexico, and is smuggled across the borders. Highly organized drug cartels are spreading the drug throughout the country. Its street nickname is “China White” or “China Girl,” referring at where most of the drug is thought to be coming from. The DEA estimates that drug traffickers can buy a kilogram of fentanyl powder for $3,300 and sell it on the streets for more than 300 times that, generating nearly a million dollars.5

As a street drug, fentanyl can be injected intravenously, taken orally, or snorted nasally. Each of these routes poses a threat:

  • Intravenous fentanyl as a street drug – Prior to fentanyl, heroin was the injectable street drug of choice. Because of the extremely high strength and potency of pure fentanyl powder, it’s difficult to dilute appropriately. The diluted mixture may be far too strong and, may cause respiratory depression and death. Some heroin dealers mix fentanyl powder with heroin to increase potency or compensate for low-quality heroin. Because fentanyl is more potent than heroin, the presence of even small quantities of fentanyl in injected heroin can result in respiratory depression. The fentanyl sold on the streets is likely made in a non-pharmaceutical lab, and is less pure than the medical version anesthesiologists administer. Its effect on the body can be hard to predict. Heroin and fentanyl look identical, and with drugs purchased on the street, addicts don’t know what they’re taking. An intravenous fentanyl overdose can cause a person to cease in breathing within minutes of injection, and result in death. Narcan, or naloxone, is a specific antagonist of narcotic overdose. Administration of Narcan as a fentanyl overdose antidote is a potential acute rescue remedy. 
  • Oral fentanyl as a street drug – Fentanyl is also sold as an oral street drug. Ten people died in just twelve days from fentanyl-laced pills in Sacramento County, California in March of 2016. In San Francisco, fentanyl showed up in pills labeled as Xanax, which turned out to be pure fentanyl. After 26 years in a Orange County crime lab south of Los Angeles, forensic scientist Terry Baisz said, “I was shocked the first time I tested this stuff and it came back as fentanyl. We hadn’t seen it before 2015.” Dealers were describing their pills as Xanax or Oxycodone. The tablets looked nearly identical to products manufactured by commercial pharmaceutical companies, although the pills sold on the streets contained fentanyl.6 The singer Prince’s death in 2016 was due in part to an overdose of fentanyl, likely in a pill form of counterfeit hydrocodone-acetaminophen (Vicodin) tablets.7
  • Intranasal fentanyl as a street drug – If fentanyl is supplied to the addict in powder form, and the powder is confused with cocaine and is snorted intranasallly, the addict may die. A hospital in New Haven, Connecticut treated twelve overdoses, three of them fatal, in just an eight-hour period in June 2016 among addicts who were snorting a white powder they purchased on the city’s streets. 8The powder they believed was cocaine turned out to be fentanyl. The absorption of a nasal dose of fentanyl can lead to immediate respiratory depression and death.

U.S. Surgeon General Jerome Adams, an anesthesiologist, has suggested distributing the narcotic antagonist Narcan freely, so that onlookers can quickly treat fentanyl-overdosed individuals.9 I respect Dr. Adams at the highest level, but I’m skeptical of this approach. An addict injecting fentanyl while he or she is alone is still at high risk of dying, and I’m not aware of any statistics documenting whether addicts reliably have company present while they are injecting themselves.

First response Emergency Medical Technicians should carry Narcan. Treatment of patients who are discovered comatose for unknown reasons has long included an empiric injection of Narcan to reverse possible narcotic overdose. The public needs to be aware of the existence of fentanyl powder, its ultra-high potency, and the danger of a fatal overdose immediately after the intravenous injection, oral ingestion, or intranasal inhalation of any street drug. There’s a real threat that any dose of street fentanyl can be lethal.

In our operating rooms, hospitals, surgery centers, and intensive care units, fentanyl is used safely. On the streets, fentanyl poses nothing but problems. Education, prevention, and DEA enforcement will have key roles in addressing the crisis of fentanyl in non-medical settings.

INTRAVENOUS ACETAMINOPHEN: AN IMPORTANT NON-OPIOID THERAPY, OR AN EXORBITANTLY PRICED VERSION OF AN OVER-THE-COUNTER MEDICATION?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Intravenous acetaminophen was introduced in Europe in 2002. The United States Food and Drug Administration approved IV acetaminophen (Ofirmev, Cadence Pharmaceuticals) in 2010 for management of mild to moderate pain, moderate to severe pain with adjunctive opioid analgesics, and reduction of fever.

Acetaminophen (Tylenol) has been available in oral and rectal forms for decades.

Oral acetaminophen

 

Healthcare costs continue to skyrocket in the United States. In 2016 Americans spent $435 billion on prescription drugs.1 This month the Trump administration released a 44-page blueprint for executive action on drug pricing entitled “American Patients First.” Their goal is to drive prescription drug costs down by increasing competition. At this time it’s too early to tell how effective these efforts will be.

Anesthesiologists are the only physicians who prescribe and then directly administer medications themselves. CRNAs are the only nursing professionals who prescribe and then directly administer medications themselves. Because anesthesiologists and CRNAs typically don’t pay for the medications, there can be a disconnect regarding costs and value.

If you were in charge of pharmaceutical purchasing at a hospital or an ambulatory surgery center, and you had an identical acetaminophen molecule available for either 5 cents per dose or $42 per dose, which would you choose? The answer is obvious, but as an administrator you are not prescribing the drug.

A 2014 study showed that patients who received IV acetaminophen reported superior satisfaction with pain control compared to patients who received placebo.2 In inpatient and postoperative settings, intravenous acetaminophen became a route of choice for rapid analgesia, and appeared to reduce the need for other analgesics such as opioids. Disadvantages of IV acetaminophen included the time and equipment needed for IV drug administration, as well as increased costs.

In a publication from the Canadian Journal of Hospital Pharmacy, Jibril wrote, “The study drug (acetaminophen, either oral or IV) was given when patients first awakened after surgery, and additional doses were given every 6 h until 0900 the next morning. . . . The use of opioids was significantly lower in the group receiving acetaminophen by the IV route than in the group receiving acetaminophen by the oral route (p < 0.05). However, this difference did not translate into a significant difference in rates of postoperative nausea and vomiting or any significant difference in pain scores on a 100-mm visual analogue scale (VAS) at any time. . . . A major finding of this review was the absence of strong evidence suggesting superiority of IV acetaminophen administration over oral routes. . . . IV acetaminophen may be useful for opioid-sparing in postoperative pain. To date, no strong evidence exists that IV acetaminophen should replace any form of standard care. At most, the evidence indicates that this formulation could function as an adjunctive agent in patients unable to take oral forms. . . . . In the United States, there has been great debate regarding use of this formulation, which has led many hospitals to adopt policies and procedures that restrict use for a limited period or for patients not able to take medications by mouth. These restrictions are required because of the cost of the product, in addition to other administration-related inconveniences. Canadian hospitals and formulary committees should be aware of the available efficacy and safety data if the formulation is marketed in Canada and its use becomes widespread. Given the high cost and the lack of superiority over oral forms, Canadian hospitals may need to restrict use of the IV formulation, as their US counterparts have already done.”3

In a study of IV acetaminophen use in neurosurgical ICU patients at Virginia Commonwealth University, Gretchen Brophy, PharmD, of the departments of pharmacy and neurosurgery wrote, “We and every institution I’ve spoken to have restricted its use, because we don’t have data saying it’s more effective. At $33 a dose” – recently up from $10 – “it’s harder to justify. At least in the 0-3 hour window, it didn’t have any additional benefit over oral. It might still be better at 1 hour; kinetically, that would make sense, but there’s nothing yet to say from what we did that it’s better.”4 VCU restricted intravenous acetaminophen use to one dose per patient.

Mallinckrodt purchased Cadence Pharmaceuticals in 2014, and increased the price of Ofirmev from $17.70 to $42.48 per vial. (A full case of Ofirmev includes 24 vials.) Sales increased to $71 million during their fiscal first quarter, double the amount for the same period the previous year. Hospitals noted the rise in expenses and sought alternatives such as oral acetaminophen, and the volume of sales dropped. Robert Press, chief of hospital operations at NYU Langone, which anticipated $1 million in additional costs because of Ofirmev, was quoted to say, “We found out a lot of the use was really not necessary and we found we could give alternative products.”5

Some hospitals removed Ofirmev from their formularies after the price went up. Others simply switched to alternatives such as oral acetaminophen. Others increased their budgets to cover the cost of the drug, but the net effect of Mallinckrodt’s price hike was to reduce the doses of Ofirmev prescribed. Mallinckrodt’s U.S. headquarters are located in Missouri. Senator Claire McCaskill (D-Missouri) wrote a letter to Mallinckrodt CEO Mark Trudeau demanding information about pricing and revenue numbers. In the letter she also suggested that Ofirmev, expensive as it was, might actually be saving hospitals money because of opioid-sparing. Senator McCaskill wrote, “Any obstacle to prescribing non-opioid alternatives, even those used solely in a hospital setting, is cause for concern.” It should be noted that McCaskill received $2,500 in campaign financing from Mallinckrodt during the 2016 election cycle.6

Mallinckrodt released a statement that read, “One recent analysis of health economic data on the use of Ofirmev coupled with a one-level reduction in opioid use was linked to decreasing hospital stays, potential opioid-related complications and related costs for the treatment of acute surgical pain. . . . The study showed a potential of $4.7 million in annual savings for a typical, medium-sized hospital.”6

The clinical benefit of reduced opioid consumption with Ofirmev has not been evaluated nor demonstrated in prospective, randomized controlled trials. In a review in the journal Pharmacotherapeutics, Yeh wrote, “Although use of intravenous acetaminophen has reduced other postoperative resource utilization (e.g., hospital length of stay) in some studies outside the United States in patients undergoing abdominal surgery, a full economic evaluation in the United States has yet to be undertaken.”7

The research study anesthesiologists would like to read is a prospective, randomized, double-blind trial of 1000 mg of preoperative oral acetaminophen, versus 1000 mg of IV acetaminophen administered just prior to the end of surgery. Will this research ever be performed? I hope so, but you can bet Mallinckrodt is never going to fund that study.

I repeat Jibril’s conclusion to sum up the answer to our initial question above:“An absence of strong evidence suggesting superiority of IV acetaminophen administration over oral routes. . . . To date, no strong evidence exists that IV acetaminophen should replace any form of standard care. At most, the evidence indicates that this formulation could function as an adjunctive agent in patients unable to take oral forms. . . . Therefore, on the basis of current evidence, if a patient has a functioning gastrointestinal tract and is able to take oral formulations, IV formulations are not indicated.”3

And what is the solution regarding anesthesia providers who frequently choose to prescribe IV acetaminophen despite these recommendations? The hospital I work at, Stanford University Hospital, restricts Ofirmev usage to patients who are NPO (nothing by mouth), and each Ofirmev order has a hard stop after 24 hours, eliminating further usage. The owners of the surgery center I medically direct have an even more decisive solution: Ofirmev is not on the facility formulary at all.

LEARJET ANESTHESIA – THE EARLY DAYS OF HEART TRANSPLANTATION

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Learjet anesthesia? Yes, anesthesia can be a glamorous specialty. During my Stanford training in 1984-1986 I flew on Learjets more times than I can count, during missions to harvest donor hearts from throughout the western United States.

learjet-lear-60

Norman Shumway MD PhD, a Stanford surgical professor and legend, invented the heart transplantation procedure and performed the first heart transplant in the USA on January 6, 1968 in operating room 13 of Stanford University Hospital. Survival rates for heart transplantation patients increased markedly in 1983 with the adoption of cyclosporine as an effective anti-rejection drug. During the 1980’s Stanford was the only prominent heart transplantation program in the western United States, and the quantity of brain dead heart donors was modest. In order to expand their volume of transplants, Stanford created a fixed-wing aircraft harvesting and transportation program to bring donor hearts to Palo Alto from distant locations.

One registered nurse had a fulltime job locating appropriate brain dead heart donors within a 60-90 minute Learjet trip from Stanford. A separate team of physicians and nurses was responsible for assembling a waitlist of prospective heart transplant recipients, and for arranging housing for them within the San Francisco Bay Area.

When Stanford learned of a brain dead donor with a normal heart at a distant location, the following choreography occurred: 1) a matching donor was identified and told to come to Stanford Medical Center immediately; 2) a team of surgeons, anesthesiologists, nurses, and a heart-lung perfusionist was paged to Stanford Medical Center immediately to prepare the recipient patient for his or her transplant surgery; and 3) a transport team of two surgeons (a chief resident in cardiac surgery and a second surgical resident), one anesthesia fellow or resident, one scrub nurse, one circulating nurse, and the nurse in charge of the transport team were all paged to the Stanford Medical Center immediately.

Note that the anesthesia transport team member was only an anesthesia fellow or a resident. The eligible residents were second-year residents (anesthesia residency training was only two years in duration during the 1980’s). As a second-year resident, I was a partially trained anesthesiologist who had done only 800-1000 anesthetics at that time, and was not yet eligible to sit for the American Board of Anesthesia exam.

An ambulance transported our team to the Moffett Field Air Force Base, 10 miles southeast of the Stanford campus, where we boarded a Learjet for the flight to the donor hospital. The donor harvesting catchment area was as far north as Seattle, as far south as Las Vegas, and as far east as Boise. We had no medical tasks to do in flight, and we spent our time looking out the windows and small talking. Upon arrival at the airport in the donor city, an ambulance transported us to the hospital.

At the hospital we proceeded to the intensive care unit where we found the donor’s brain dead body connected to a ventilator and ICU monitors. At this point my work began. Even though the patient was brain dead, it was imperative to maintain his or her vital signs and oxygenation at optimal levels to preserve the cardiac function for the eventual recipient. My first tasks were to insert an arterial line in the radial artery to monitor blood pressure, and to insert a central venous pressure catheter in the internal jugular vein to administer medication infusions as needed to decrease or increase the blood pressure during the upcoming surgery. We would then transport the patient through the hallways of this foreign hospital, accompanied by the surgeons, and directed by staff of that hospital who knew the floor plan. I’d be squeezing an Ambu bag full of oxygen to ventilate the patient, all the while vigilant of the vital signs displayed on a portable monitor during the transport.

We’d arrive in the operating room—a room we’d never seen or worked in before—and prepare the patient for surgery. My job was to connect the patient to the operating room ventilator and the standard cardiac surgery monitors: ECG, oximeter, arterial line, and central venous pressure. The manufacturers of the monitoring equipment varied from hospital to hospital, and it was not unusual for the equipment to be different than machines I’d worked with before. My next task was to prepare vasoactive drips such as nitroprusside and connect them to the central venous pressure IV line. No anesthetic drugs were used, because the donor was brain dead, but surgical stimulus always caused increases in blood pressure and heart rate. It was critical that pumping against a high resistance or pumping at a high rate not tax the donor heart. I also had to fill out a written anesthesia medical record to document what I was doing to the patient.

The scrub tech, nurse, and the two surgeons prepped and draped the patient for surgery, and the initial incision was made over the sternum. A power saw was used to cut the breastbone down the midline to enter the chest. A rib-spreader was used to widen the cavity and improve visualization. The surgeons inspected the heart in terms of its general appearance, size, contractility, and the state of the coronary arteries. Once they’d determined the heart was indeed normal, the transplant nursing coordinator made a phone call to the Stanford operating room in California to inform them it was a green light to anesthetize the heart recipient there.

In our operating room, the two surgeons clamped off the aorta and all other blood vessels leading into and out of the heart, and injected a cardioplegic solution into the coronary arteries via the root of the aorta. This solution preserved the heart function during the upcoming trip when the heart would no longer be beating. The surgeons then cut the heart out of the body, placed it in a sterile bag, and placed the bag into an Igloo chest full of ice. I turned off the ventilator, the surgeons removed their gloves and gowns, and our whole cast scurried out of the operating room with the Igloo and its precious cargo in hand.

It was always a bizarre sight to see that human carcass with an empty thorax lying on an operating room table when we left the operating room. In the later months of my Learjet experiences, a second transplant team was sometimes present to harvest the kidneys or corneas after we departed.

The original ambulance met us at the Emergency Room entrance, and we sped back to the airport Code 3 with alarms blaring. We drove onto the tarmac next to the Learjet and climbed inside. The doors closed, engines flared, and wheels up . . . we were on our way back to Palo Alto.

The flight home was relaxing. We’d spent an intense period of time at the hospital, and we had no work to do except to ride and look out the windows. Beverages and food were always supplied for the trip home. The mood was jubilant—the feeling you get with medical jobs when you realize you’ve accomplished something. We were helping the recipient patient in their journey back to health, and experiencing private jet travel at 35,000 feet at the same time.

On arrival to Moffett Field, an ambulance awaited us on the tarmac. We’d climb in and ride at top speed back to Stanford. We stopped in front of the Emergency Room, and the surgeons and the nurse coordinator ran through the doorway and up the stairs to operating room 13, where the anesthetized recipient patient lay, his or her chest open, ready to receive the new heart at once.

At this point I went home. An anesthesia resident colleague and an anesthesia faculty member were upstairs attending to the recipient. Caring for the recipient patient was their job for today—mine was finished.

How stressful was the entire journey to harvest the new heart? Pretty stressful, to be honest. At that point, I’d done less than two years of anesthesia training, and I was relatively inexperienced. During my training, a faculty member always stood right next to me during every anesthesia induction and a faculty member was immediately available at all times. On the Learjet trips I was without faculty backup for the first time. The setting at the destination hospital was always unfamiliar. The equipment on hand at the destination hospital was often unfamiliar. The cardiac chief resident surgeon was typically an intense 39-year-old who’d been training for decades and who had little interest in waiting any longer than possible while an anesthesia resident-in-training toiled to insert an arterial line and a central venous catheter. Even though the patient was brain dead, there was no tolerance for errors in ventilation or medical management, it was imperative to keep the vital signs stable throughout the donor surgical procedure, and there was time pressure to keep the process moving.

Prior to my anesthesia residency I’d completed three years as an internal medicine resident at Stanford and one year as an attending in the Emergency Room at Stanford. All my experience in internal medicine and emergency medicine was useful on those heart-harvesting trips—but I knew how lucky I was. Internal medicine residents don’t get to ride Learjets, and ER attendings don’t get to ride Learjets either.

An added motivation: We were paid $35/hour for our time, a princely sum in 1986.

Alas, none of this would happen nowadays. Currently there are hundreds of cardiac transplantation programs in the United States, and each program procures their donor hearts from close geographic proximity.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too.

Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?”

The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

ARE SURGERY CENTERS SAFE?

THE ANESTHESIA CONSULTANT

Are surgery centers safe? This column is in response the Kaiser Health News story “How a push to cut costs and boost profits at surgery centers led to a trail of deaths” published on USAToday.com this week. The article set off a firestorm of controversy in the surgery center industry. The Kaiser article cites anecdotal information and allegations from ongoing litigation cases of patients seemingly harmed by their care at outpatient ambulatory surgery centers.

outpatient-surgery-e1451859891882

The quantity of ambulatory surgery centers has greatly increased over the past forty years for three primary reasons: Technologic advances made surgery easier, anesthetic care is safer, and healthcare payment policies encourage ambulatory surgery. I’ve been the Medical Director at a busy freestanding ambulatory surgery center in Northern California for a decade and a half. I’m a Stanford University-trained anesthesiologist and internist, and I’m uniquely qualified to answer the question: Are American surgery centers safe?

Yes, they are safe.

A review of the medical literature on Pubmed shows no peer-reviewed studies or data that surgery centers provide less safe care than hospitals.

Surgery and anesthesia are never 100% safe, no matter where procedures are done. There are always risks. The roles of anesthesiologists and surgeons at surgery centers are to minimize the risks.

There are four key questions regarding safe patient care at surgery centers:

  1. Is the scheduled procedure appropriate for an outpatient surgery center?
  2. Is the patient healthy enough to tolerate the scheduled procedure as an outpatient?
  3. Are the healthcare professionals at that center practicing at the standard of care?
  4. Is the surgery center accredited by an organization such as the Accreditation Association for Ambulatory Health Care (AAAHC)?

 

Question #1.

The most important screening question for a surgery center is, “What is the scheduled procedure?” Knee arthroscopies, tonsillectomies, inguinal hernia repairs, and colonoscopies are standard surgery center procedures. You cannot do large cases such as craniotomies, open heart surgeries, or an aortic vascular surgeries at a surgery center. The necessary backups of an intensive care unit, a blood bank, respiratory therapy, and a clinical laboratory are lacking. The job of a Medical Director is to survey the schedule each week, and decide if any planned cases are outside the usual comfort zone for that center. If there is any question, the Medical Director must gather more information on the procedure and the patient, usually by talking directly to the surgeon, and decide whether or not to give the case a green light. If the verdict is a red light, the surgeon needs to do the case in a hospital.

In recent years, some surgery centers have expanded their scope. Procedures such spine surgeries, total joint replacements, and bariatric surgeries are performed as ambulatory or short stay procedures at some outpatient centers. As the USAToday.com article points out, one motivation is money. A surgery center can extract well-insured cases from hospitals in order to increase profits for the surgery center. Is it better for a patient to have these procedures in a freestanding facility detached from a hospital? There is a paucity of research in peer-reviewed medical literature regarding the performance of these cases outside of hospitals. The USAToday.com article lists multiple spine surgery patients who died after surgery at an ambulatory surgery center. Medicare has only approved payment for spinal surgery at ambulatory centers since 2015. To my knowledge, no one has published the overall statistics regarding complications from spinal surgery in surgery centers and compared this to the complications from similar procedures in hospital settings.

What about the claim from the USAToday.com article that 911 calls from a surgery center are a problem? If a patient unexpectedly becomes acutely ill at a surgery center, calling 911 and transferring the patient to a hospital is routine policy and appropriate medical care.

 

Question #2.

How does a facility decide whether a patient is fit enough to undergo a given surgery at an outpatient center? At a surgery center, it’s the Medical Director’s job to screen every patient prior to scheduling. It’s the Medical Director’s job to prevent patients who are too sick from having a procedure at a surgery center. Different systems exist for preoperative assessment. Large university hospitals staff preoperative anesthesia clinics for their patients, and patients are required to physically visit the clinic to be examined and assessed prior to inpatient surgery. This system is not always practical in outpatient community medicine. Patients are usually assessed by their primary care physicians as indicated before surgery. A typical preoperative screening protocol at a surgery center is as follows: a preoperative assessment professional from the surgery center will telephone each patient several days before surgery, ask a series of pertinent screening medical questions, and fill out a standardized form. Any outlying answers are referred to the Medical Director, who decides if the patient is fit for the surgery. If the patient is too sick, the Medical Director will cancel the case, and tell the surgeon that the surgery needs to be done in a hospital.

 

Question #3.

When a complication occurs, anesthesiologists and surgeons in the operating room have a responsibility to correctly diagnose the problem and apply the correct therapy. The legal term for this is that physicians must adhere to the “standard of care.” The standard of care is defined as “what a reasonably trained physician would do in the same circumstance.” Deviating from the standard care is called negligence, and is part and parcel to medical malpractice lawsuits. If a bad outcome occurs in a surgery center because of negligence, i.e. malpractice, this is not a fault of the surgery center system. This concept is a central flaw in the USAToday.com article. The article cites multiple bad outcomes from surgery center cases, and in many of these cases the central issue seems to be negligent, below the standard of care decisions and actions by the health care professionals involved. Negligence is not specific to surgery centers.

 

Question #4.

Most surgery centers provide care to Medicare patients, and must meet standards approved by the federal government. To obtain Medicare certification, a surgery center must have an inspection conducted by a representative of an organization that the government has authorized to conduct that inspection, such as the Accreditation Association for Ambulatory Health Care (AAAHC). Inspectors will physically visit the surgery center to verify that the center meets established standards. Most surgery centers have passed such an inspection. The surgery center I work at is recertified every three years. If you’re uncertain whether your local surgery center is safe, request documentation that the facility has been certified by an organization such as AAAHC.

Nearly 60% of all surgical procedures in the United States are performed as outpatient surgery. Tens of millions of Americans receive care in ambulatory surgery centers each year. I’ve personally had two arthroscopic surgeries and three colonoscopies, and I chose to have all five procedures at a freestanding outpatient surgery center. The USAToday.com article cited anecdotal adverse outcomes from patients who were cared for at outpatient ambulatory surgery centers. Adverse outcomes will occur, but the frequency of these events (adverse events vs. total number of cases) is extraordinarily small. America’s surgery centers are by and large very safe. I reaffirm that no peer-reviewed data documents that ambulatory surgery centers are unsafe.

The key issues regarding surgery center safety will always be the four questions posed above. Is a given procedure safe and appropriate for an outpatient surgery center? Is a given patient fit enough to have their particular procedure in an outpatient surgery center? Are the healthcare professionals at that center practicing at the standard of care? And is the surgery center accredited by an organization such as the AAAHC?

In the overwhelming majority of America’s surgery centers, the answers to these three questions will be “Yes, yes, yes, and yes.”

THE ANESTHESIA CONSULTANT

You’re a 55-year-old man with hypertension, scheduled for surgery for a right colon removal for colon cancer. How likely is your death within 30 days after surgery?

Higher than you would think.

1482936925_5

Your 30-day morality following this inpatient surgery is 1.2%. What can we do to improve myocardial injury after noncardiac surgery? Read on…

Dr. Daniel Sessler, Chairman of the Department of Outcomes Research at the Anesthesia Institute of the Cleveland Clinic, spoke at the Stanford Anesthesia Grand Rounds last week. His lecture, titled “Perioperative Myocardial Injury,” answered the questions above. Let me share what Dr. Sessler had to say:

  1. Myocardial injury after noncardiac surgery, abbreviated as MINS, is a common, silent, and deadly problem. Dr. Sessler described mortality related to surgery as the third leading cause of death in America, behind cardiovascular disease and cancer, and he cited myocardial injury as the leading cause of death after surgery.
  2. Devereaux, Sessler, and colleagues measured postoperative hsTnT (high sensitive troponin T) in 21,842 patients over the age of 45 who had inpatient noncardiac surgery at 23 medical centers in 13 countries.1 (For my nonmedical readers: hsTnT or cardiac troponin is a biomarker for acute myocardial infarction, i.e. heart attack.) Two hundred sixty-six patients died within 30 days after surgery, for an overall mortality rate of 1.2%. A total of 3904 patients had elevated hsTnT, diagnostic for MINS, for an overall incidence of tropinin elevation = 18% of the patients. Ninety-three percent of these patients had no ischemia-related symptoms, and would not have been detected without the hsTnT measurements.
  3. Puelacher published similar data in an older population (all patients over the age of 65).2 He studied postoperative hsTnT levels in 2018 consecutive inpatients and found perioperative myocardial injury (PMI) occurred in 397 (16% of the patients). Only 24 (6% of the patients) had typical chest pain, and only 72 (18% of the patients) had ischemic symptoms. The 30-day mortality was 8.9% for patients with PMI, compared to 1.5% for patients without PMI.
  4. hsTnT isn’t commonly measured in current practice, which means the majority of MINS patients go undiagnosed. Sessler recommended that all patients diagnosed with MINS be seen by a cardiologist, to consider further diagnostic or therapeutic intervention. He specifically mentioned the possibilities of statin and/or aspirin therapy, as well as smoking cessation and weight loss.
  5. Sessler suggested that a future approach to MINS detection would be to measure postoperative hsTNT for three days in every inpatient noncardiac surgery patient over 65 years old, and in those over 45 with one or more cardiovascular risk factor.
  6. What about preoperative clearance for noncardiac surgery? Sessler described exercise tolerance and the echocardiogram cardiac stress test as two inaccurate screening tools. He rated the two most effective screening tools as the Revised Cardiac Risk Index (see below), and the preoperative measurement of BNP (Brain Natriuretic Peptide).
  7. The Revised Cardiac Risk Index (RCRI) evaluates these 6 patient factors:

■ High-Risk Surgery – the following surgeries are deemed high risk for perioperative cardiac complications:

-­ Intraperitoneal

– Intrathoracic

– Suprainguinal vascular

■ History of ischemic heart disease – characterized by either a history                                     of a positive test, a diagnosed MI, current chest pain suspicion of                                                 myocardial ischemia, nitrate therapy, or evidence of                                                             pathological Q waves on electrocardiogram.

■ History of congestive heart failure – described as the presence of                                     either:

– Pulmonary edema, bilateral rales or S3 gallop;

– Paroxysmal nocturnal dyspnea;

– A CXR showing pulmonary vascular redistribution.

■ History of cerebrovascular disease – e.g. a prior TIA or stroke.

■ Pre-operative insulin treatment.

■ Pre-operative creatinine more than 2 mg/dL.

 

Positive findings of these factors define 4 classes of postoperative                                     cardiac complication percentage rates:

■ 0 factors – Class I – risk 0.4%;

■ 1 factor – Class II – risk 0.9%;

■ 2 factors – Class III – risk 6.6%;

■ 3 to 6 factors – Class IV – risk 11%. 

  1. Preoperative BNP concentration is a powerful independent predictor of perioperative cardiovascular complications.3 At best, clinicians can utilize both a low score in the preoperativeRevised Cardiac Risk Index plus a low value of the BNP or the N-terminal proB-type natriuretic peptide (NT-proBNP) plasma level.4 Sessler stated that a BNP test costs 1/20th as much as an echo stress test, and is more accurate in predicting postoperative cardiac mortality. He stated that a NT-proBNP level of < 300 ng/mL correlated well with a safe perioperative cardiovascular course.
  2. Elevated preoperative troponin or hsTnT concentrations were also significantly associated with postoperative MI and long-term mortality after noncardiac surgery.5
  3. Metoprolol, aspirin, and clonidine all failed as preoperative interventions to decrease cardiac risk. Metoprolol decreased postoperative myocardial infarction, but there were more deaths and an increased rate of stroke in the metoprolol group than in the placebo group.6 Aspirin before surgery and throughout the early postsurgical period had no significant effect on the rate of death or nonfatal myocardial infarction, and increased the risk of major bleeding.7 Low-dose clonidine did not reduce the rate death or nonfatal myocardial infarction, and increased the risk of clinically important hypotension and nonfatal cardiac arrest.8
  4. Eliminating nitrous oxide from the anesthetic regimen had no effect in decreasing myocardial injury.9
  5. Intraoperative hypotension correlated with postoperative myocardial injury. Mascha studied the time-weighted average intraoperative mean arterial pressure (TWA-MAP), and found that lower mean arterial pressure strongly correlated with mortality.10 Sessler stated that a mean blood pressure of 50 torr for even one minute was a risk factor for postoperative myocardial injury. Targeting a specific systolic blood pressure reduced the risk of postoperative organ dysfunction.11
  6. Sessler stated that 1/3 of intraoperative hypotension occurred during the time between induction of anesthesia and time of the surgical incision. By analyzing large databases from electronic anesthesia recording systems, hypotension was documented during this time period when general anesthesia lacked any surgical stimulus to keep blood pressure elevated. Sessler’s recommendation was to maintain the MAP > 65 torr throughout noncardiac surgery.
  7. The use of vasopressors to treat hypotension was safe.
  8. Tachycardia was not a risk factor. “It hardly matters,” Sessler said.
  9. Preoperative angiotensin-converting-enzyme inhibitors (ACE inhibitors), e.g. lisinopril, Lotensin, or Altace, and Angiotensin II receptor blockers (ARBs), e.g. Diovan or Cozaar, were risk factors for intraoperative hypotension and cardiovascular morbidity. Roshanov studied data from 14,687 patients aged 45 years or older for inpatient noncardiac surgery.12 Four thousand eight hundred and two of these patients were taking ACE inhibitors or ARBs preoperatively. The patients who withheld their ACE inhibitors/ARB drugs in the 24 hours before surgery were less likely to suffer the outcomes of death, stroke, or myocardial injury. The authors recommended that patients withhold these drugs for 24 hours before surgery.

 

Dr. Sessler closed his lecture with the following recommendations:

  • In the future, clinicians should measure high-sensitivity troponin (hsTnT) for three days postoperatively on inpatient surgery patients of age > 65, or patients age >45 with one cardiovascular risk factor. Elevated shTnT will identify patients who with MINS, and these MINS patients should be referred for cardiology/internal medicine follow up.
  • In the future, clinicians should screen for preoperative cardiovascular risk by a combination of the BNP and hsTnT assays prior to surgery.
  • There is no known preoperative medical prophylaxis against MINS.
  • Maintain intraoperative mean arterial pressure > 65.
  • Hold ACE inhibitors/ARBs for 24 hours prior to surgery.

One of our professors asked Dr. Sessler if the current practice at the Cleveland Clinic included measuring preoperative BNP and three-day postoperative hsTnT. Sessler’s answer was, “not yet, but we’re working on it.”

What about your practice and mine?

This is a new topic and a cutting edge issue to most anesthesiologists, with the key studies only published in the last year. I’m impressed by the MINS data, and I don’t want any patient of mine joining the MINS mortality list. I already withhold ACE inhibitors/ARBs for 24 hours preoperatively. I will continue to be vigilant to maintain MAP > 65, using vasopressors as necessary. I currently use the Revised Cardiac Risk Index as well as cardiology consultations as indicated to screen patients preoperatively. At the present time both the cardiologists and I depend on exercise tolerance history and echo treadmill tests for preoperative cardiac clearance. I expect in the near future our healthcare systems will adopt the standards of checking BNP preoperatively and hsTnT for three days postoperatively for inpatient surgery patients of age > 65, or patients age >45 who have one cardiovascular risk factor. Stay tuned for future recommendations.

The year was 1999, the technology stock market was exploding, and businessmen in Silicon Valley were getting richer by the hour. Meanwhile, back at the metaphor, anesthesiologists practiced their essential healing profession, and hoped HMOs and hospital administrators would not decrease their anesthesia quantum wage any further.

The cartoon won an Honorable Mention award at the ASA national meeting in 1999.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

Some people have difficulty seeing the outstanding merits of physician anesthesiology. I understand where these opinions come from, but the phenomenon still bothers me.

Today I read a thoughtful and well-written essay in Anesthesiology News titled, Anesthesiologists-The Utility Players of the Medical Field written by anesthesiologist David Stinson MD from my native state of Minnesota. His thesis is that, like utility players on a baseball team, we are valuable but suffer an identity crisis. He writes, “Our specialty, anesthesia, has suffered an identity crisis for decades. Are we the ‘captain of the ship’ or is the surgeon? . . . It is never quite clear and the answer changes with location and context. Are we physicians or are we glorified advanced practice nurses?”

To me, the appropriate headline should read, “Anesthesiologists—the Most Valuable Players of the Medical Team.” I’d like to see an anesthesiologist saying, “I’m going to Disney World” at the end of the Super Bowl before picking up his (or her) MVP trophy.

Why would I say this? Two anecdotes will illustrate why I understand the problem. In the late 1970’s I was a third-year medical student at a prominent Midwestern medical school, where an unspoken rank system existed in the operating room. The surgical attendings were the kings, the students were the peasants, the nurses and techs were serfs, and the anesthesiologists were the whipping boys for the surgeons. I witnessed consistent verbal abuse, bullying, condescending barking commands, and lack of respect directed from surgeons toward anesthesiologists. One day I was scrubbed in as a retractor-holding medical student on a 12-hour esophagectomy, and at the conclusion of the procedure the attending surgeon removed his gloves and gown and left the room to talk to the family. Five minutes later, the patient had a cardiac arrest. The resuscitation was not successful, and the patient died. Afterward the surgeon bellowed his disapproval regarding how the anesthesia team had failed to keep the patient alive after he had spent all day “curing” the patient. It was an unforgettable experience to me, and one of the take-home messages was that I never wanted to be an anesthesiologist.

Fast-forward three years into the future, when I was an internal medicine resident at Stanford serving my medical intensive care unit rotation. The anesthesiology department ran the ICUs at Stanford during the 1980’s. The ICU attendings were charismatic, smart, decisive, impressive role models. The ICU attendings had respectful peer relationships with all the surgeons, including the private-practice cardiac surgeons whose post-operative patients were housed in the ICU. Morning rounds, evening rounds, and the eight hours in between were filled with action, procedures, upbeat emotions, and encouraging talk about the specialties of anesthesiology and critical care medicine. The Stanford anesthesia residents boasted of weekdays off after their nights on call, Learjet trips to harvest donor hearts for Dr. Norm Shumway’s cardiac transplant patients, weeklong trips to third-world countries to perform anesthetics on cleft lip and palate patients, and best of all, the excitement of inserting endotracheal tubes, arterial lines, central lines, Swan Ganz catheters, spinal and epidural needles into patients of all sizes and surgical needs. This was alluring to internal medicine residents. Each year a significant number of internal medicine residents applied for admittance to anesthesiology residencies, which is what I did. Were surgeons hollering at the anesthesiologists at Stanford? In a word . . . no. The department had the respect of the surgeons. This was the environment I grew up in, and the professional spirit we all should aspire to.

Here are 10 reasons why anesthesiologists should hold their heads high and never have a molecule of low self esteem around their medical center:

  1. All of acute care medicine is based on A-B-C, or Airway-Breathing-Circulation. Operating room medicine, intensive care medicine, emergency room medicine, trauma helicopter medicine, and battlefield medicine are all based on A-B-C, or Airway-Breathing-Circulation. Who are the experts of the A, or Airway? Anesthesiologists are the experts. There can be no acute care resuscitation without someone managing the airway, usually with an endotracheal tube. It’s true that other medical professionals have abilities to place endotracheal tubes, but none of them have the breadth of skills, techniques, and volume of attempts as anesthesiologists do. Hold your heads high. Read my column on bullying in the operating room. Don’t put up with condescending behavior from a surgeon. Surgeons know how to wield a scalpel. You know how to wield the most valuable tool of all medical equipment, the laryngoscope.78432-7985650
  2. It’s true that surgeons bring the patients to the operating room for surgery. It’s just as true that none of those patients would agree to the operations without having an anesthetic. The anesthesiologist’s role is vital.
  3. Clinic doctors are important. They manage primary care as well as outpatient specialty care. They make diagnoses and prescribe therapeutic medicines. Anesthesiologists also partake in clinic care in preoperative clinics and pain clinics. An anesthesiologist’s knowledge of internal medicine isn’t as comprehensive as a board-certified internist, but the consider the flip side: None of the internists can administer general anesthesia, regional anesthesia, or manage the A of the A-B-Cs like an anesthesiologist can. I was an internal medicine doctor who lacked these skills and then acquired them during anesthesia residency. Trust me—internists envy the skills of anesthesiologists.
  4. Anesthesiologists deal with life and death situations on a regular basis. Clinic doctors, including surgeons on their days in clinic, listen to and talk to patients. There is no peril in outpatient clinic medicine. On any given day at your job as an anesthesiologist you could be attending to a morbidly obese adult, a tiny child, a frail geriatric patient, or an emergency thoracic case. Your heart rate will climb as high as the patient’s, and you’ll manage the circumstances. Anesthesiologists are goalies at the Pearly Gates, and we should be proud of it.
  5. Physician anesthesiologists have a fascinating job. Anesthesiologists administer anesthetics to virtually every specialty: general surgery, cardiac surgery, neurosurgery, obstetrics, gynecology, otolaryngology, orthopedic surgery, podiatry, ophthalmology, plastic surgery, psychiatry for electroshock therapy, invasive radiologists, cardiologists, oral surgeons, dentists, and pediatric surgeons. The breadth of knowledge across specialties is unrivaled by any other physician.
  6. Who is the captain of the ship in the operating room? Is it the surgeon or is it the anesthesiologist? My advice is: don’t concede the role to your surgical colleague alone. He or she knows how to do the operation. You know how to do the anesthetic. It is a symbiotic relationship. Do not lay yourself down on the ground in reverence. In the words of the Eagles song “Peaceful Easy Feeling,” “she can’t take you anywhere you don’t already know how to go.” If you see and feel yourself as the servant, second in command, that’s where you’ll find yourself . . . as the servant, second in command. Step up. Be an equal. Be in control of your domain, a critical domain.
  7. Physician anesthesiologists are well paid. Per U. S. News and World Report, an anesthesiologist is the highest paying job in America. Think about that. There are 325 million people in our country, and there are thousands of different job descriptions. Your profession is the highest paid. Be proud of that.
  8. Physician anesthesiologists are in demand. As I write this in 2018, I receive multiple emails per day seeking attending anesthesiologists for jobs around the USA. If you’re willing to relocate and be mobile, you’ll find numerous suitors competing for your services as an attending anesthesiologist. Per U.S. News and World Report, the unemployment rate for anesthesiologists is a paltry 0.5%.
  9. Physician anesthesiologists help people every day. You could be selling Coca Cola or cell phones or cell phone data networks or stocks. Would you be serving humanity as well if you were working in some business job? You have the opportunity to change lives for hundreds of patients per year.
  10. Maybe you’re worried that nurse anesthetists will take your job away. I have no crystal ball to foretell the future, but consider these things: (a) Most CRNAs work in anesthesia care team models with our physician anesthesiologist colleagues, and this MD-CRNA relationship is a well accepted model of patient care that will persist into the future; (b) Physician anesthesiologists are needed for leadership roles in clinical care, administration, committees, and quality assurance; and (c) Remember that you are a physician and CRNAs are not. Keep up your skills. The large medical systems of the future will tier their anesthesia coverage. Complex cases will always require MD anesthesiologists. It’s likely that simple cases such as cataracts, lymph node biopsies, and knee arthroscopies can be safely done with CRNA anesthesia. Continue to seek out and perform difficult anesthetic cases only an MD would feel comfortable doing. If you find yourself attending to only ASA I an ASA II patients for straightforward surgeries, you may indeed find your job taken by someone with less training. Instead, step up. Be proud of your training, your unique skills, the heritage of your profession, and the esteem of your standing among your fellow physicians.

THE ANESTHESIA CONSULTANT

For years I’ve extolled the intellectual and emotional virtues of a career in anesthesiology. This week U.S. News and World Report credited anesthesiologist with another honor: the highest paying job in their 2018 Best Paying Jobs survey.

usnewsjobs2016_main

Regarding the #1 job, physician anesthesiologist, the article states, “the breadth of the profession has dramatically expanded in the last decade. Anesthesiologists still work in hospital operating rooms, but their expertise is also needed in other places, including invasive radiology, gastrointestinal endoscopy, electrophysiology and more. In fact, the profession is expected to grow by 18 percent through 2026, with 5,900 new jobs.” The median salary for a physician anesthesiologist was listed as $208,000, and the unemployment rate as 0.5%.

The article also states, “The journey to becoming an anesthesiologist is a long one. After obtaining an undergraduate degree, hopefuls need to take the Medical College Admission Test (MCAT) and attend medical school. After graduation, they will then have to pass the United States Medical Licensing Examination (USMLE) to undergo a one-year internship followed by a three-year residency in anesthesiology. Most anesthesiology residents go on to do a one- to two-year fellowship program to learn a subspecialty, such as critical care or obstetric anesthesia. After completing residency and taking an exam, anesthesiologists may also receive their board certification through the American Board of Anesthesiology. It’s not required, but it does demonstrate advanced skill and knowledge and many help with getting more professional opportunities or a higher salary. However, all anesthesiologists have to obtain state licensure, the requirements for which vary by state. By the time an anesthesiologist is through residency and a fellowship, he or she will have completed anywhere from 12,000 to 16,000 hours of clinical training, according to the American Society of Anesthesiologists.”

The job of a certified nurse anesthetist was listed as #11 on the Best Paying Jobs list. The article states, “health care reform and the aging baby boom population are precipitating the demand for more health care providers. And indeed, the BLS (Bureau of Labor Statistics) predicts that the profession is poised to grow by about 16 percent by the year 2026, which translates into 6,700 new job openings.” The median salary of nurse anesthetists was listed as $160,270, and the unemployment rate as 2.7%.

Careers in anesthesia are intellectually stimulating, emotionally gratifying, and have high median salaries and ultra-low unemployment. Expect the demand for acceptance into physician anesthesiologist and nurse anesthetist training programs to remain high. I see both careers to remaining attractive and secure for the foreseeable future.

WHEN SURGEONS, OR PATIENTS, TRY TO TELL THE ANESTHESIOLOGIST WHAT TO DO — 14 EXAMPLES

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

You’re a board-certified anesthesiologist. You’ve graduated from a residency program in which you learned the nuances of preoperative, intraoperative, and postoperative anesthesia practice. Yet at times, surgeons or patients will ask you to do something counter to your medical judgment.

cert

Individuals would never board a Boeing 787 aircraft and tell the pilot what to do, but individuals will try to influence their anesthesiologist.

Let’s look at some examples:

 

WHEN SURGEONS TRY TO TELL THE ANESTHESIOLOGIST WHAT TO DO:

SONY DSC

  1. “This patient’s not too sick. You’re wrong to cancel his surgery.” In an example of this scenario, an orthopedic surgeon tries to convince you that the 65-year-old obstructive sleep apnea patient with a BMI of 40 who never walks further than the distance from his couch to his kitchen table is “not that sick,” and that you should not cancel the patient’s rotator cuff repair at a freestanding outpatient surgery center. Trust your training and your intuition. You believe the patient is high risk in terms of his airway, his breathing, his cardiac status, and his potential for post-operative complications. You’re trained in perioperative medicine. The orthopedic surgeon is trained in the management of joint and bone disorders. Tell the surgeon that the patient needs to have cardiac clearance prior to any general anesthetic, and that the case needs to be done in a hospital setting rather than at a freestanding surgery center.
  2. “Just do MAC (Monitored Anesthesia Care) anesthesia for this case, but make sure he’s asleep. My patient doesn’t want to hear anything.” In an example of this scenario, a surgeon schedules an inguinal hernia repair as a MAC anesthetic. The surgeon intends to supplement your intravenous (IV) sedation with local anesthetic at the surgical site. The surgeon told the patient to expect “a twilight sleep during the surgery.” You discuss this with the surgeon, who requests you, “Just give the patient sedation with propofol.” Per the American Society of Anesthesiologists Continuum of Depth of Sedation, if a patient is unarousable even with painful stimulation, that is a general anesthetic. In contrast, if a patient shows purposeful response following repeated or painful stimulation, that is deep sedation. It’s possible to infuse propofol and keep a patient purposefully responsive, but very few of us do this. Propofol infusions are typically used to make our patients sleep, and most propofol infusions cross the American Society of Anesthesiologists line into general anesthesia. If there is a complication or a bad outcome after the surgery, and you delivered general anesthesia when the operating room schedule said MAC and your preoperative anesthesia note stated the anesthesia plan was MAC, then you’re at medical-legal risk for delivering a deeper anesthetic than what was documented on the schedule and on your anesthetic plan.
  3. “Can you do an axillary block for this finger surgery?” In an example of this scenario, the surgeon requests an axillary block for a debridement of a finger surgery. You’re comfortable placing ultrasound-assisted regional anesthetic blocks, but you’re not confident with this particular block. You discuss other options with the surgeon, and suggest he places a digital block, which is more specific and incurs less risks than the axillary block. He pushes back, wanting you to do the axillary block. But if you don’t want to do the block, you don’t have to. You’re in charge of the anesthetic. You make the decision. The case proceeds with intravenous sedation, the surgeon complies with your request and blocks the base of the finger with local anesthesia, and the patient does fine.
  4. “This patient doesn’t need an arterial line (or a central venous pressure line).” In an example of this scenario, an 70-year-old woman with aortic stenosis is about to undergo an exploratory laparotomy for a perforated bowel. You’re concerned about maintaining her cardiac output, blood pressure, and blood volume during the surgery, and decide she needs an arterial line prior to induction and an internal jugular CVP after induction. The surgeon, in a hurry to proceed with the laparotomy, tells you neither of these lines is necessary. Your answer? Because you’re the expert in perioperative medicine, you tell him you need those lines and you will put them in. If there is a death or a dire cardiovascular complication, you’ll be the physician who will face the criticism if you did not place the lines. Blaming the surgeon will not protect you.
  5. After the conclusion of a surgery, the surgeon says, “What are you waiting for? Extubate the patient. She is bucking and coughing. Extubate the patient!” In an example of this scenario, after the conclusion of a tonsillectomy, you turn off the anesthetics. The patient eventually coughs and bucks on the endotracheal tube, but has not opened her eyes. When you open her eyelids, you note that her gaze is dysconjugate. You’re concerned that if you extubate the trachea, this still-emerging patient could develop laryngospasm. The surgeon then says, “When are you going to extubate? All this coughing is raising the blood pressure, and will cause bleeding and I’ll have a complication.” What should you do? Anesthesia practice must always follow the priorities of A-B-C, or Airway-Breathing-Circulation. You’re in charge of the airway. The endotracheal tube is your friend until the patient opens her eyes, is awake and responsive, and can maintain her own airway. Take out the breathing tube when you’re ready, not when the surgeon asks you to.
  6. Near the conclusion of surgery the surgeon says, “I’d like you to please extubate this patient deep.” In an example of this scenario, a patient has just received a five-hour general anesthetic for a facelift. As in the example above, the surgeon is concerned that coughing or bucking on the endotracheal tube at emergence will elevate the blood pressure and cause increased postsurgical bleeding. What should you do? Again, follow your training and experience. Anesthesia practice must always follow the priorities of A-B-C, or Airway-Breathing-Circulation. You’re in charge of the airway. The endotracheal tube is your friend until your patient opens her eyes, is awake and responsive, and can maintain her own airway. Certain slender, healthy patients are safe to extubate deeply, but this author is unconvinced of the benefit/risk analysis of deep extubation. You may make the surgeon happy, and you may continue to have a safe airway under general anesthesia in the absence of the endotracheal tube, but what if you don’t? What if the airway is poorly maintained in this patient after this five-hour surgery, when her entire head and jaw are wrapped up in a bulky facelift dressing? My advice is to take out the breathing tube when you’re ready, not when the surgeon asks you to.
  7. “Just give the patient a little bit of anesthesia, because my procedure will only last 10 minutes.” In an example of this scenario, the surgeon requests you sedate a 210-pound woman with a Body Mass Index (BMI) = 36 for a 15-minute egg retrieval. Because of the brief and seemingly trivial nature of the procedure, the gynecologist requests an anesthetic free of any airway tubes. You assess the patient and her airway, and decide you’ll need to use a laryngeal mask airway (LMA), with an endotracheal tube ready to go if the woman’s ventilation on the LMA is suboptimal. You explain to the surgeon that you’re doing what is safe, despite the requests the surgeon made. On obese, elderly, pediatric, or sicker patients, there are simple surgeries, but there are no simple anesthetics. Rely on your experience and training, and do the anesthetic by the standard of care.
  8. “I’d like to do this procedure in my office operating room, not in a surgery center or the hospital.” In an example of this scenario, the surgeon has a patient he’d only like to operate on in his office. You’ve worked at his office before, and you know his office operating room does not have an anesthesia machine. Your technique there is limited to IV sedation without any airway tubes or ventilation. You discover that the patient is an obese 45-year-old woman with a BMI = 32, and the planned procedure is implantation of a maxillary bone graft. Your concern is that you will not be able to safely sedate or anesthetize this woman for this oral surgery without a breathing tube or an anesthesia machine. The surgeon objects, and says that the woman does not have enough money to pay for the procedure to be done at the local outpatient surgery center, and that’s why he needs to do it in the office. You stand firm, and kindly refuse to do the anesthetic in his office.

 

 

WHEN PATIENTS TRY TO TELL THE ANESTHESIOLOGIST WHAT TO DO:

thumbnail_fotolia_87299704_subscription_monthly_m

  1. “I don’t want a breathing tube into my windpipe and voice box because I’m a singer and I don’t want my voice ruined.” In an example of this scenario, a 35-year-old 250-pound man with a BMI of 34 who sings in a rock ‘n roll band is about to have a lumbar laminectomy. He does not want to be intubated. He read about anesthesia on the Internet, and he wants you to use an LMA instead of an endotracheal tube. Your response? You advise him that per your experience and training, his only safe airway management is with an endotracheal tube, not with an LMA. You tell him that yes, he will have a sore throat after surgery, and the irritation to his vocal cords may cause a temporary hoarse voice. You advise him that the duration of the hoarse voice should be no more than several days or a week or two, and that it’s rare for any voice change to be permanent. You advise him that he can consent to the endotracheal tube with these risks, or he can refuse. If he refuses the appropriate airway tube management, you will decline to give him anesthesia today.
  2. “I want to be awake for my surgery, so I can watch and talk to the surgeon.” In an example of this scenario, a 55-year-old woman scheduled for a knee arthroscopy wants to be awake for the surgery. She is visibly nervous, and tells you she wants to be awake because she is afraid of dying during a general anesthetic. You discuss the options with the patient, which include spinal anesthesia, epidural anesthesia, or regional blocks, each accompanied by intravenous sedation if necessary, which will permit her to be comfortable and awake. She declines each of these. She just wants “some medicine in the IV to take the edge off while I’m still awake, just like I did with my last colonoscopy.” You discuss with her that knee surgery is more painful than a colonoscopy. You discuss with her that she will need more anesthesia than she is requesting. You leave the bedside and talk to the surgeon about the options. The surgeon is agreeable with injecting local anesthesia into the knee, as a supplement to the intravenous sedation you will administer. The patient, the surgeon, and you all agree with this plan. You also give the patient informed consent that if she is not comfortable, she may need more anesthesia medications from you and she may have to go to sleep. Begrudgingly, she consents. Five minutes into the surgery, despite 200 micrograms of IV fentanyl, 6 milligrams of IV midazolam, and appropriate 2% lidocaine injections into the knee joint by the surgeon, the patient is uncomfortable, crying, and in a state of panic. You begin an infusion of propofol, she goes to sleep, and the ordeal is over. She awakens in the PACU without complications and without complaints. In my experience, many patients who demand or insist on being awake during surgery are patients who hope to control circumstances in the middle of surgery, rather than trusting their anesthesiologist and surgeon. Don’t be surprised if these patients wind up requiring general anesthetics. Make sure you have preoperative informed consent for general anesthesia as a back up, because it’s likely you’ll need to administer it.
  3. A patient who’s been in the PACU (Post Anesthesia Care Unit) for an hour tells you, “I want more intravenous narcotics.” In an example of this scenario, a patient who had an arthroscopic anterior cruciate ligament (ACL) reconstruction is complaining of 8/10 pain ninety minutes postoperatively. He’s received 300 micrograms of fentanyl and two Percocet in the PACU, and says he is still uncomfortable. You go to his bedside, and witness that he is in no acute distress. His vital signs are normal, with a respiratory rate of 12 breaths per minute. He refused a femoral nerve block prior to surgery. Because he’s been medicated, the option of having him sign a consent and performing a femoral nerve block now is out of the question. Your assessment is that his pain score is inflated. One man’s 8/10 may be another’s 3/10. His respiratory rate is already low normal, and he’s received the adjunct of 30 mg of IV Toradol, as well as the Percocet. At this point in my practice I have the following conversation with the patient: I tell them, “You’ve already had the standard pain-relieving medications, including the oral medication the surgeon prescribed for home use. One option now would be to hospitalize you so that you can continue to receive IV narcotics, but we don’t hospitalize healthy patients after routine ACL reconstruction. A second option is for you to stay here in the PACU and continue to receive IV narcotics, but that makes little sense because you cannot continue IV narcotics at home. So the remaining option is for you to be discharged on the oral medication Percocet that the surgeon prescribed.” There’s a point after routine outpatient surgeries where there’s no rationale for the continued administration of IV narcotics, and the patient needs to be discharged home on their oral medications.
  4. Your awake patient in the PACU says, “I’m so anxious. Can I have more of that Versed you gave me before surgery?” In an example of this scenario, a patient with chronic anxiety wakes up from an uneventful anesthetic with complaints of nervousness. The role of the PACU staff is to monitor Airway-Breathing-Circulation while tending to common postsurgical complaints such as pain and nausea until the anesthetics wear off sufficiently for discharge. In my residency, my professors taught me that benzodiazepines were valuable preoperatively but have no role in the PACU, and I still follow this principle. The PACU is a temporary destination prior to discharging a patient home or to their hospital room. Sedating these patients with Versed or any other benzodiazepine in the PACU will prolong their recovery and is not indicated. The best treatment for PACU anxiety is often to discharge the patient out of the PACU.
  5. Your next patient is a child. His parent tells you, “I want to be in the operating room when my son goes to sleep. He needs me.” In an example of this scenario, the mother of a 3-year-old patient wants to accompany her son into the operating room to emotionally support the boy during a mask induction with sevoflurane. The scheduled procedure is bilateral ear pressure-equalizing tubes surgery. This author believes that parent(s) can be a distraction during the potentially dangerous time of mask induction of anesthesia. I’ve done thousands of pediatric inductions without parental presence, and I never wished I had a layperson there at my elbow while I was trying to assure safe airway management. Letting the child watch an iPad as they separate from their parents and engage in the anesthesia induction is a modern solution to this problem.
  6. A preoperative patient with a dangerous airway problem (think ankylosing spondylitis or Treacher Collins syndrome) tells you, “I refuse to have an awake intubation. I need the general anesthesia first before you put in that breathing tube.” In an example of this scenario, an 18-year-old boy with Treacher Collins syndrome and a very abnormal airway refuses awake intubation for an emergency appendectomy. Your assessment of his airway is that you will not be able to visualize the vocal cords with either traditional laryngoscopy or video laryngoscopy. You’re uncertain you can mask ventilate the patient if he is asleep either. You tell him he can be sedated and relaxed for an awake intubation, but you cannot administer general anesthetic prior to his intubation, for safety reasons. Per a study on this very topic, you decide to use dexmedetomidine , which has minimal respiratory depression, to sedate him, and you acquire the assistance of a second anesthesiologist to monitor the patient and manage the sedation while you apply topical anesthesia to the airway and drive the fiberoptic scope. After thirty minutes of work, the two of you manage to successfully insert the endotracheal tube, and the surgery can begin.

 

The overwhelming majority of anesthesiologist-surgeon and anesthesiologist-patient interactions are positive. But when conflicts such as these examples occur, the take-home messages are:

  1. YOU ARE THE BOARD-CERTIFIED SPECIALIST IN ANESTHESIA. IT IS YOUR JOB TO MAKE THE ANESTHESIA DECISIONS.
  2. SURGEONS ARE SPECIALISTS IN SURGERY. THEY ARE NOT SPECIALISTS IN ANESTHESIA OR PERIOPERATIVE MEDICINE.
  3. YOU PAY YOUR OWN MALPRACTICE INSURANCE, AND YOU HAVE TO ANSWER TO THE CONSEQUENCES IF YOU GET SUED. IF YOU ARE SUED, THE KEY QUESTION WILL BE “DID THE ANESTHESIOLOGIST PRACTICE AT THE STANDARD OF CARE?” REPLYING THAT THE SURGEON OR THE PATIENT TALKED YOU INTO A SUB-STANDARD PRACTICE IS NO DEFENSE. IT IS YOUR JOB TO MAKE THE ANESTHESIA DECISIONS.
  4. THE CORRECT ANESTHETIC PLAN IS THE SIMPLEST ANESTHETIC PLAN THAT ALL THREE PARTIES (THE SURGEON, THE PATIENT, AND YOU) AGREE TO.

Are you unhappy with your current anesthesia job? Are you considering finding a new job, relocating, changing your case mix, payer mix, or increasing your income? Are you a resident or fellow or a nurse anesthetist looking for your first job?

Every week thousands of anesthesiologists and nurse anesthetists are looking for new employment. Individuals are seeking a new geographic location, a higher income, or more autonomy. Clients (healthcare systems/employers) are seeking candidates (physician anesthesiologists or CRNAs) for locum tenens help, part time help, or as fulltime employees.

The best job opportunities are usually spread via word of mouth. For example, alumni of your training program will seek out fellow graduates of the same program. You interview with their group, and ideally you’re offered a job. But what if you aren’t hearing about any job opportunities which interest you?

Internet websites post job advertisements for anesthesia professionals. Many of the advertised jobs are salaried positions, at a modest pay range, in locations which may or may not be popular. At the current time you will find thousands of job openings for full time, part time, and locum tenens anesthesiologists on Internet listings.

The American Society of Anesthesiologists website http://careers.asahq.org/jobs posts job openings, many of them for academic positions.

Current healthcare staffing websites listing anesthesia positions include Gasworks.com, Indeed.com, or Glassdoor.com.

Finding a promising job listing on these sites is only the beginning, to be followed by a complex process of applying to the listing company and/or the listing client healthcare system, and waiting to see if you are hired.

An innovative new medical staffing company named BlocHealth has entered the business of matching anesthesia candidates with client hospitals/healthcare systems. BlocHealth shows promise to be a game changer for physicians or nurse anesthetists looking to relocate, or physicians or nurse anesthetists looking for their first job. When you click on Blochealth.com you aren’t greeted with random listings of multiple job offerings—you’ll be matched with jobs based on your preferences.

The definition of a “bloc” is a combination of parties or groups sharing a common purpose. BlocHealth’s proposes to redefine the healthcare staffing industry by enabling providers to find staffing opportunities that uniquely match their talent, experience, and lifestyle. BlocHealth aims to do this without the complicated fees and back and forth processes of preexisting staffing companies.

BlocHealth aims to work with candidates to get you the highest rates possible, all the while keeping in mind the client/healthcare system’s bottom line. BlocHealth is “candidate-centric,” which means physician anesthesiologists and CRNAs have more control over the process and the pay rate they will accept. BlocHealth’s goal is to make the process of finding a position much more efficient, whether you are looking for locum tenens, part time, or permanent positions anywhere in the United States.

The BlocHealth website (www.blochealth.com) promises innovation in healthcare staffing via three specific strategies:

  1. Cost savings. BlocHealth’s profit is an industry-low percentage of the transaction amount. Existing staffing companies often charge a 30% profit off the top. This decreased cost to employers/clients promises significant cost savings to employers, and encourages them to list with BlocHealth.
  2. Transparency is a BlocHealth core value. Candidates will be kept in the loop with all details of the job search from start to finish.
  3. The BlocHealth process is unique. The website does not initially present a listing of anesthesia job offerings. Instead, each candidate physician anesthesiologist or CRNA fills out a brief form which primarily asks where you want to work, what dollar amount per hour you want to be paid, and then asks you to upload your curriculum vitae. A BlocHealth representative will then contact you via email or phone to discuss further specifics.

With BlocHealth:

  1. You, the candidate, have the control. You can search for opportunities by specialty, case types, availability, and pay rate.
  2. You, the candidate, set the pay rate you want. There are no recruiters pressuring you to lower your rate to inflate an agency’s profit margin.
  3. It’s a quicker process. There is less dealing with recruiters, and more finding the positions you want.
  4. You’ll have access to easy-to-view hospital profiles.
  5. You’ll have access to extremely detailed job descriptions.
  6. You can directly message hospitals with interest.
  7. You can be matched to high quality jobs. Candidates will be notified when their profile matches 90%+ with a job. Case types, location, shifts, dates, etc. will be taken into consideration when matching.
  8. Candidates can see what clients have checked out their profile pages.

BlocHealth is different from the preexisting companies. Older companies:

  1. Offered the candidate little control of the process. Recruiters at agencies presented which opportunities they believed the candidate should consider.
  2. Controlled too much of the price negotiation. Recruiters were motivated to convince candidates to take less money so they and their company can earn more money.
  3. Require too many steps, instead of the shorter smoother BlocHealth process, before successfully matching a candidate with a new job opportunity.

I recommend you check out BlocHealth—it’s a new way of doing business.

Uber presented a new model which had significant price and access advantages over taxis. BlocHealth aims to similarly slash the market share of other Internet healthcare staffing companies, and help find you a new job in the process.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

THE ANESTHESIA CONSULTANT

One goal of theanesthesiaconsultant.com is to make the practice of anesthesia safer. The practice of anesthesia on healthy patients is quite safe, but we want to do everything we can to avoid preventable errors.

maxresdefault

The safety of anesthesia on ASA I and II patients has been compared to the safety record of commercial aviation. Few passengers board an airplane and worry they will die before they land at their destination. But planes do crash, and so do anesthetized patients.

In August 2107 the journal Anesthesiology published the study “Frequency and Type of Situational Awareness Errors Contributing to Death and Brain Damage,” authored by Christian M. Schulz MD et al. . This was an important study which documented what experienced anesthesiologists already know—although our specialty has never been safer, preventable deaths still occur.

The study analyzed the United States Anesthesia Closed Claims Project database of 10,546 malpractice claims between 2001-2013. A total of 266 cases of brain damage or death during anesthesia care in the operating room under the care of a solo anesthesiologist occurred. Of these 266 cases, 198 (74%) had a situational error by the solo anesthesia provider. Malpractice payments were made in 85% of these situational error cases, compared to only 46% in other cases. The total of 198 patients in 12 years averaged more than16 preventable deaths per year.

What was the definition of a situational error? The article sited three types: perception, comprehension, and projection.

PERCEPTION ERROR. A failure to gather information via history, the patient’s chart, physical exam, diagnostic tests, imaging, or monitors, including the absence of monitors.

COMPREHENSION ERROR. The information was available, but there was a failure to understand and diagnose the significance of information obtained from history, physical exam, diagnostic tests, imaging findings, or monitors.

PROJECTION ERROR. A failure to forecast future events or scenarios based on a high-level understanding of a problematic situation.

Of the 198 situational errors, perception errors were most common (42% of the cases), followed by comprehension errors (29%) and projection errors (29%).

72% of the errors occurred during general anesthetics, 23% occurred during monitored anesthesia care, and 5% occurred during regional anesthetics.

The primary damaging event differed in the 198 error cases vs. the 68 other cases. In the 198 situational error cases, respiratory events were the dominant category (p<.001), including inadequate oxygenation/ventilation (24%), difficult intubation (11%), and pulmonary aspiration (10%). In the 68 non-error cases, cardiovascular events were the dominant category. All the anesthesiologists were single practitioners, that is, they were not part of an anesthesia care team with a nurse anesthetist.

The authors of the study made the following points in their discussion of the findings:

  1. Many perception errors stemmed from lack of or lack of attention to respiratory monitoring. Key respiratory monitors were pulse oximetry and end-tidal CO2 monitors.
  2. Other common perception errors were missing preoperative information, which led to inadequate preoperative evaluation.
  3. The most common comprehension error was failure to comprehend an ongoing clinical difficulty related to respiratory problems.
  4. Many projection errors involved lack of appreciation of difficult airways.
  5. Projection errors also included procedures taking place in inappropriate environments, such as very sick patients having surgery in an office or an outpatient surgery center.

The authors made the following suggestions to decrease preventable errors:

  1. Perception errors may be prevented by regular scanning and processing of all the information available prior to and during every anesthetic.
  2. A “call for help” and the use of cognitive aides (e.g. emergency checklists or an emergency manual) may help when a patient deteriorates.
  3. Situational awareness training can be addressed in anesthesia crisis resource management education, including simulation training.

There were limitations to the Schulz study. The assembled data was retrospective and nonrandom. The Anesthesia Closed Claims Project may not reflect the true incidence of situational errors in anesthesia practice in the United States. As well, the 198 patients found in this study are only those countable via the closed malpractice claims. The true number of uncaptured cases of preventable deaths is unknown.

I have a busy practice of medical-legal consultation. I evaluate 8-10 cases per year of preventable death or brain death, and I’m just one person with one medical-legal practice. I believe there are far more cases that exceed my reach.

The Schulz study listed 11 specific patient case examples of preventable errors. Based on these 11 cases, the multiple legal cases referred to me, my 31 years of practice, and my 25,000 personally administered anesthetics for all types of surgeries and patients, I’m qualified to give advice on how to decrease preventable errors in anesthesia. My advice follows:

  1. I see uninformed preoperative workups leading to errors. Be an outstanding preoperative physician. Your preoperative assessment of each patient needs to be complete and pertinent. Pay special attention to cardiac, respiratory, neurologic, and any other significant medical issues. If you’re uncomfortable with any lack of information, you must acquire that information before you begin an anesthetic. If you need a consultant such as a cardiologist, cancel the case and get a cardiac consult before you proceed.
  2. As part of your preoperative workup, ask every patient if they can climb two flights of stairs. Be wary when administering general anesthesia to any patient who cannot walk up two flights of stairs. If a patient develops shortness of breath at this modest exertion, this is evidence of a lack of cardiac or respiratory reserve. This requires preoperative workup to determine the diagnosis and to apply treatment prior to general anesthesia. Any patient who has significant knee, hip, foot, or back pain or who has claudication that prevents him or her from walking up two flights of stairs has not proven to you that they have adequate cardiac and/or respiratory reserve. A referral to a cardiologist/pulmonologist/internist for preoperative clearance testing may be indicated prior to surgery.
  3. Don’t let surgeons talk you into anesthetizing patients you believe are inadequately worked up for anesthesia. Don’t let surgeons talk you into anesthetizing patients using anesthesia techniques or anesthesia plans you’re not comfortable with. We give mock oral board exams to residents at Stanford, and a common exam question is to try to dupe the resident into doing something unsafe because the surgeon demanded it. The surgeon is not trained in anesthesiology. The surgeon does not pay your malpractice insurance, and he or she will not have to endure your malpractice lawsuit if the anesthetic goes awry.
  4. Don’t let surgeons talk you into anesthetizing patients in inappropriate locations or settings. Be careful anesthetizing sicker patients in offices or in freestanding outpatient surgery centers. These facilities lack ICUs, clinical labs, blood gases, respiratory therapists, radiology, and backup anesthesia professionals. Be wary of performing procedures which are too invasive or too extensive in these settings. Twenty years ago one of our orthopedic surgeons attempted to schedule an 80-year-old female for a total knee replacement in a freestanding outpatient surgery facility which had overnight capabilities. I refused to staff the case, and told him, “Cases like this—that’s why we have hospitals.” He hung up on me, but there were no further requests to schedule similar patients at that facility. There are pressures to perform increasingly difficult procedures on increasingly sicker patients in non-hospital settings. Resist these pressures. There can be no surgery without an anesthetic. Be consistent with the values you learned in your university residency program. These values haven’t changed—they’re called the standards of care—and they reflect what an adequately trained physician will do in any give situation. Stay within these standards of care, and you’re unlikely to ever lose a malpractice lawsuit.
  5. The highest number of malpractice cases I review involve airway disasters. Do not screw up airway management. This includes intubation, extubation, and mask ventilation. I’ve previously written on this topic, and I can’t emphasize it enough.
  6. Because the highest number of malpractice cases I review involve airway disasters, I’d advise you to commit the ASA Difficulty Airway Algorithm to memory. I recommend Dr. Phillip Larson’s approach to the difficulty airway, as presented in the Appendix to Richard Jaffe’s Anesthesiologists Manual of Surgical Procedures. Patients with airway emergencies deteriorate in minutes. Have a plan in mind before you begin.
  7. Because the highest number of malpractice cases I review involve airway disasters, I recommend you always have a videoscope available. All well-stocked hospital operating rooms will have a Glidescope or equivalent, but many freestanding outpatient surgery centers or office-based operating rooms will not. It’s not always possible to predict the difficulty of endotracheal intubation. If you work at facilities or offices without a videoscope, I recommend you carry a disposable single-use Airtraq in your briefcase. The devices are single-use, and can be invaluable or lifesaving when conventional laryngoscopy is unsuccessful.
  8. Keep a reference book of checklists for dealing with anesthesia disasters available in every anesthetizing location. My recommendation is the Stanford Anesthesia Cognitive Aid Group Emergency Aid. Should a disaster occur, all the steps to appropriate treatment are listed so that you can follow those steps.
  9. Review the Stanford Anesthesia Cognitive Aid Group Emergency Manual regularly, and memorize the steps to each algorithm. The checklists exist so that in a disaster clinicians will not forget any steps, but a solid anesthesiologist will know this information by heart. You had to learn all this information to pass your oral anesthesia board exam, so why would you allow yourself to forget them as your career proceeds? Why would you want to be anything less than the safest practitioner you can be?
  10. A high percentage of the malpractice cases I review involve obese patients. Be extra wary when attending to obese patients. Obese patients present multiple difficulties in terms of airway management, placement of anesthesia lines, safety of oxygenation and ventilation both in the operating room and postoperatively, and they also present increased challenges for your surgeon. Anesthetics on patients with a BMI > 30 are more difficult, and anesthetics on patients with a BMI >40 or >50 are always challenging. I refer you to a previous column on the risks of obese patients for anesthesia.
  11. If you’re ever wondering whether or not to place an arterial line for a non-cardiac case, I’d recommend you place one. I was a cardiovascular anesthetist at Stanford for 15 years, and during that time I placed countless radial arterial lines prior to induction. The procedure is relatively painless, and for the sickest patients the benefit/risk ratio is high. The second-to-second feedback regarding hypotension or hypertension can be essential in patients with limited cardiac reserve, in trauma patients, or in patients with shock. An arterial line will be much more difficult to place if you wait until your patient is already hypovolemic, vasoconstricted, or hypotensive. And if the patient’s arms are tucked or if the patient is in a position other than supine, you’ll have restricted access to the radial artery intraoperatively. My advice: if you’re pondering whether or not to place an arterial line prior to inducing a sick patient, just do it.
  12. Be vigilant. The maintenance phase of anesthesia can at times be long, tedious, and boring, but it’s mandatory we stay vigilant for developing problems. Scan all patient monitors and all aspects of the patient during anesthesia care. Look for trends, e.g. increases or decreases in blood pressure or heart rate. Note any decrease in oxygen saturation, airway pressures, or end-tidal CO2 patterns. Diagnose and treat any abnormalities early in their development.
  13. Don’t struggle alone. Call for help early if your patient deteriorates. In anesthesia residency programs, each resident has multiple faculty members and other residents to assist him or her if a patient becomes acutely ill. In community practice there is almost always a second anesthesiologist or a second acute care physician in the facility to help. A second pair of hands can be invaluable in assisting airway or vascular procedures. A second mind is useful in confirming diagnoses and therapies are correct. An anecdote from my own anesthesia practice: an 80-year-old patient developed severe hypertension leading to frothing pulmonary edema just prior to extubation at the conclusion of a twenty-minute elbow surgery. My colleague in the next operating room left his stable anesthetic, arrived in my room, and placed an arterial line while I tended to the heart and lung emergency. Once the arterial line was placed, I was able to acutely titrate a sodium nitroprusside drip to normalize the blood pressure, decrease the afterload, and regain adequate oxygenation. The patient recovered fully. Without my partner’s help, it’s likely the patient would have died of hypoxemia.
  14. I’ve seen several cases of undetected hemorrhagic shock. Don’t be afraid to speak up to your surgeon. If your surgeon is working in the abdomen or the chest and your patient develops an increasing heart rate and a decreasing blood pressure, this could be the presentation of hemorrhage. The surgeon needs to know if the vital signs are deteriorating. If major hemorrhage occurs, you’ll need to insert a second large-bore IV line, get help, and order a Massive Transfusion Pack from the blood bank.

The Schulz study was an important publication. Preventable errors do occur in anesthesia. It’s up to us to do everything we can to make the incidence of preventable errors in our practice approach zero. You’ll keep your patients safe, and you’ll stay away from bad outcomes and malpractice lawsuits.

ARTIFICIAL INTELLIGENCE IN MEDICINE

THE ANESTHESIA CONSULTANT

I’m fascinated by the topic of artificial intelligence in medicine. This is the third column in a series regarding robots in medicine. (See Robot Anesthesia and Robot Anesthesia II)

ai-medical-1-orig

AI already influences our daily life. Smartphones verbally direct us to our destination through mazes of highways and traffic. Computers analyze our shopping habits and populate our Internet screens with advertisements for products we’ve ogled in the past. Smartphones perform voice-to-text conversions by pattern recognition of human vocal sounds. Fingerprint scanners learn and then recognize the image of our thumbprints with exacting accuracy. Amazon’s Alexa is an AI-powered personal assistant that accepts verbal commands in our homes.

What about AI in medicine (AIM)? AIM is a bold enterprise on the horizon in clinical medicine. Hundreds of AIM scientific publications appear in medical journals each year. I’m not an AIM researcher, but I’m an expert clinician and I love to read. I’ve worked in almost every scenario of medical practice, and because my base is at Stanford University Medical Center in Silicon Valley, many of the advances of the high-tech industry are right here in my backyard. My medical board certifications are in internal medicine and anesthesiology—two fields which have significant overlap in their knowledge base but radically different practice settings. Internal medicine doctors work in clinics, where most diseases are chronic and the most valuable tools for doctors are excellent listening and diagnostic skills. Anesthesiologists work in operating rooms and intensive care units—acute care settings which demand vigilance, steady hands, and quick thinking.

Based on my experience and my reading, I foresee AIM/robots populating three clinical arenas in radically different roles. These arenas will be: 1) diagnosis of images, 2) clinics, and 3) operating rooms/intensive care units. Let’s look at each of these in turn.

  1. Diagnosis of images    This will be the first major application of AIM. We already have electrocardiogram (ECG) machines which interpret a patient’s ECG tracing with high accuracy, and print out the diagnosis for the physician to read. This application debuted in the 1980s and is now the industry standard, although confirmation of diagnosis by a physician is important for some diagnoses such as ST-elevation myocardial infarction (STEMI). More than a few physicians have already lost the skill of reading an ECG themselves because of this device. Future applications of image analysis in medicine will be machine learning for diagnosis in radiology, pathology, and dermatology. The evaluation of digital X-rays, MRIs, or CT scans is the assessment of arrays of pixels. Expect that future computer programs will be as accurate or more accurate than human radiologists. The model for machine learning is similar to the fashion in which a human child learns. A child is not given a list of criteria which define what a dog looks like. Instead, the child sees an animal and his parents tell him that animal is a dog. After repeated exposures, the child learns what a dog looks like. Early on the child may be fooled into thinking that a wolf is a dog, but with increasing experience the child can discern with almost perfect accuracy what is or is not a dog. Machine learning is a subset of deep learning, a concept that makes automated decision-making possible. Deep learning is a radically different method of programming computers. It requires massive database entry, much like the array of dogs that a child sees in the example above, so that the computer can learn the skill of pattern matching. The program repetitively teaches a machine the identity of certain images, and the system hones this algorithm and becomes faster and more accurate in recognizing similar images. An AI computer which masters machine learning and deep learning will probably not give yes or no answers, but rather a percentage likelihood of a diagnosis, i.e. a radiologic image has greater than a 99% chance of being normal, or a skin lesion has greater than a 99% chance of being a malignant melanoma. At the present time the Food and Drug Administration (FDA) does not allow machines to make formal diagnoses, and such AI computer applications are only prototypes. But if you’re a physician who makes his or her living by interpreting digital images, there’s real concern about AI taking your job in the future. Some experts believe AIM devices will not replace radiologists, but rather will make their work more efficient and accurate. For example, AI computers can identify MRI or CT scans which are normal, freeing human radiologists to concentrate on scans where an abnormality exists. In this scenario, radiologists would not lose their jobs to AIM computers, instead radiologists who don’t use AIM machines may lose their jobs to radiologists who do use the AIM technology. In pathology, computerized digital diagnostic skills will be applied to microscopic diagnosis. In dermatology, machine learning will be used to diagnosis skin cancers, based on large learned databases of digital photographs. Dermatologists must rely on years of experience to learn to discern various skin lesions, but an AI computer can ingest hundreds of thousands of images in a period of months.
  2. Clinics  In the clinic setting, the desired AI application would be a computer that could input information on a patient’s history, physical examination, and laboratory studies, and via machine learning and deep learning, establish the patient’s diagnoses with a high percentage of success. AI computers will be stocked with information from multiple sources, including all known medical knowledge published in textbooks and journals, as well as the electronic health records (EHR)/ clinical data from thousands of previous hospital and clinic patients. AI machines can remember this vast array of information better than any human physician. AI machines will organize the input of new patient information into a flowchart, also known as a branching tree. A flowchart will mimic the process a physician carries out when asking a patient a series of questions. The flowchart program contains a series of “if . . . then . . .” branches that depend on the patient’s answers. AI will input the information sources from each new patient, and arrive at diagnoses. Once each diagnosis is established with a reasonable degree of medical certainty, an already-established algorithm for treatment of that diagnosis can be applied. For example, if the computer makes a diagnosis of asthma, then an established textbook treatment regimen of bronchodilators will be activated. It’s projected that AIM applications in clinic settings will decrease unnecessary diagnostic tests, lower therapeutic costs, and reduce the manpower needed for outpatient medicine.
  3. Operating rooms  The best current example of robot technology in the operating room is the da Vinci operating robot, used primarily in urology and gynecologic surgery. This robot is not intended to have an independent existence, but rather enables the surgeon to see inside the body in three dimensions and to perform fine motor procedures at a higher level. In my previous essays Robot Anesthesia and Robot Anesthesia II, I described models of robots designed to perform intravenous sedation or intubation of the trachea, products which are futuristic but currently have no market share. The good news for procedural physicians such as anesthesiologists or surgeons is this: it’s unlikely any AI computer or robot will be able to independently replace the manual skills such as airway management, endotracheal intubation, or surgical excision. Regarding anesthesiology, I expect future AIM robots will be hyperattentive monitoring devices which follow the vital signs of anesthetized patients, and then utilize feedback loops to titrate or adjust the depth of anesthetic drugs as indicated by these vital signs. Such a robot would not replace a human anesthesiologist, but could serve as an autopilot analogue during the maintenance or middle phase of long anesthetics, freeing up the anesthesia professional so that he or she need not be physically present. This parallels the original genesis of the role of a nurse anesthetist—to be present during stable phases of anesthetic management—so that the physician anesthesiologist could roam to other operating rooms as needed.

What will an AIM robot doctor look like? It’s unlikely it will look like a human. Most sources project it will look like a smartphone. I’d expect the screen to be bigger than a smartphone screen, so an AIM robot doctor will likely look like a tablet computer. For certain applications such as clinic diagnosis or new image retrieval, the AIM robot will have a camera, perhaps on a retractable arm so that the camera can approach various aspects of a patient’s anatomy as indicated. Individual patients will need to sign in to the computer software system—this will be done via tools such as retinal scanners, fingerprint scanners, or face recognition programs—so that the computer can retrieve that individual patient’s EHR data from an Internet cloud. It’s possible individual patients will be issued a card, not unlike a debit or credit card, which includes a chip linking them to their EHR data.

How will we define if these medical computers are truly intelligent? The accepted test for machine intelligence is the Turing test, as described by computer scientist Alan Turing in 1950. In the Turing test, a human evaluator interacts with two players via a computer keyboard. One of the players is a human and the other a machine. If the evaluator cannot reliably tell the machine from the human, the machine is said to have passed the test, and is deemed intelligent.

What will be the economics of AIM? Who will pay for it? Currently America spends 17.6% of its Gross National Product on healthcare, and this number is projected to reach 20% by 2025. Entrepreneurs realize that healthcare is a multi-billion dollar industry, and the opportunity to earn those healthcare dollars is a seductive lure. Companies are looking to merge increasing computing power available at steadily decreasing costs, big data from large EHR patient populations, and artificial intelligence with an aim to drive down the costs of health care while increasing effectiveness. Expect to see the development of increasingly cheaper AIM devices to augment the skills of human physicians, or maybe replace them in some job descriptions. The government’s medical costs may decrease if work currently done by expensive-to-train physicians is instead performed by nurse practitioners or nurses aided by artificial intelligence machines, supervised by relatively few human physicians. Google is working on an AIM project in the United Kingdom entitled DeepMind. DeepMind is using machine learning to analyze eye scans from more than a million patients, with the aim to create algorithms which can detect early warning signs of eye diseases that human physicians might miss. Google researchers have also developed an AIM computer to screen for and analyze the spread of breast cancer cells in lymph node tissue on pathology slide images. Scientists at the Memorial Sloan-Kettering Cancer Center in New York have programmed over 600,000 medical evidence reports, 1.5 million patient medical records, and two millions of pages of text from medical journals into IBM’s Watson computer. Equipped with more information than any human physician could ever remember, Watson is projected to become a diagnostic machine superior to any doctor.

There’s a worldwide shortage of physicians. The earliest a human physician can enter the workforce is age 29, after completing 4 years of college, 4 years of medical school, and 3 years of the shortest residency (e.g. internal medicine, pediatrics, or family practice residency). A major advantage of AIM is that the machines won’t require 24 years of education. Can America afford to train people for almost three decades to then sit in a clinic and perform histories and physicals on patients who have chronic illnesses such as hypertension, hyperlipidemia, and obesity? Shifting these jobs to allied healthcare providers such as physician assistants or nurse practitioners is a cheaper alternative, but what could be cheaper than an AIM machine module which either assists one physician to evaluate a vast number of patients, or an AIM module of the future which replaces the physician entirely?

When can we expect to see new AIM tools adopted in clinical practice? Web-based smartphone apps such as Your.MD and Babylon already exist to assist physicians in diagnosis. You can anticipate the application of machine learning in the diagnosis of digital images soon. The DeepMind and Watson computers are blazing a trail toward machine learning in clinical medicine. Expect the FDA to assess the new technologies, and when it is safe and appropriate, to approve machine diagnosis as part of the practice of medicine. Remember how fast we advanced from a cell phone the size of a breadbox to the powerful smartphone that fits in the palm of your hand today. In the ten years since the introduction of the iPhone in 2007, who could have imagined the vast array of applications we carry in our pocket or purse in 2017?

AIM is coming. It will arrive be sooner than we think, and in all likelihood it will be more powerful and more wonderful than we could imagine. A brave prediction: AIM will change medicine more than any development since the invention of anesthesia in 1849.

I can’t wait to see it.

What can you do to make your anesthetic safer? This is what the anesthesia experience is like for most patients: You show up for surgery, and some anesthesia professional you’ve never met or talked to appears 10 minutes before you are to be wheeled into the operating room. The anesthesia professional might be an MD, a CRNA, or both a MD and a CRNA might be involved. At an academic/university hospital, the anesthesiologist might be a resident MD in his or her first, second, or third year of anesthesia training, and that resident will then be supervised by a faculty member who is responsible for either one operating room or two.

It doesn’t have to be this way. Anesthesiologists in our practice telephone their patients the night before to discuss the anesthesia care. Some hospitals have an anesthesia preoperative clinic where patients are interviewed and examined one day or more prior to surgery. Patient questions are answered at such a clinic, but it’s uncommon for you to meet the person who actually anesthetize you at such a clinic visit.

I’m going to put on my patient advocate hat. Let’s say you’re going to have surgery six weeks from now.

  • What can you do to make your anesthesia experience safer?
  • What can you do to otherwise optimize the anesthesia care you’re about to receive?

 

Here’s my list of 11 things you can do:

  1. Don’t choose to schedule your surgery at a teaching hospital in July or August. On June 30th every year, each intern and resident physician advances one year in his or her training. An intern who finished a 12-month rotating internship suddenly becomes an anesthesia trainee as of July 1st. An anesthesia resident who trained for 12 months and performed perhaps 700 anesthetics, is now a second year resident. An anesthesia resident who trained for 24 months and performed perhaps 1400 anesthetics, is now a third year resident. Each of these residents is completely inexperienced in their new level. The curriculum for residents is more complex each year, with 2nd and 3rd year residents covering progressively more complex cases such as open heart, brain, chest, or neonatal surgeries. A faculty member will supervise each resident, but often the supervision is one faculty member covering two operating rooms concurrently. The individual who monitors you minute-to-minute during your surgery will be a relatively inexperienced resident. If you’re scheduled for surgery at an academic medical center in July or August, I’d advise you to move up your surgery to May or June instead.
  2. Using the Internet, check the roster of anesthesia physicians at the facility where you’re about to have surgery. Virtually every medical center has a list of staff anesthesiologists posted on their website, and most websites will provide a summary of each physician’s academic training. Peruse the list. Are the majority of anesthetists MDs or CRNAs, or is the staff a mix of both? Did the MDs train at reputable universities, or were they trained at hospitals you’ve never heard of? Is there a phone number you can call if you wish to speak to an anesthesiologist prior to your week of surgery if you have a special concern?
  3. Talk to your surgeon about the proposed anesthesia. He or she will usually know whether your case requires a general anesthetic, with or without a regional anesthetic (such as a spinal, an epidural or a nerve block). Ask your surgeon if they have an anesthesiologist colleague they recommend for your specific case, and ask whether you can request a specific anesthesiologist prior to the surgery date.
  4. If you have chronic health issues (e.g. heart problems, lung problems, high blood pressure, diabetes, neurologic problems, kidney failure, obesity, or sleep apnea) you can expect the surgical/anesthesiologist team to require a clearance note from your primary care physician (PCP) prior to the surgery. The purpose of this clearance is to document that no further diagnostic or treatment interventions are necessary prior to your anesthetic and surgery. This is important. Planning a visit to your PCP in the month or two prior to surgery is strongly recommended.
  5. Are you unusually sensitive to drugs, sedatives, or alcohol? Tell your anesthesiologist when you meet him or her. Without question, certain individuals are unusually sensitive to normal doses of narcotics, sedatives, and general anesthetics. These individuals are often female, petite (under 120 pounds), geriatric, or persons who rarely expose themselves to central nervous system depressants such as alcohol. Armed with this information, your anesthesiologist will administer adequate doses of drugs, but no more than the minimum necessary.
  6. The standard of care is for your anesthesiologist to explain the alternate anesthesia techniques for your surgery, as well to explain the risks and benefits of each alternative. I’d advise you to listen, ask questions, and consider the KISS principle (Keep It Simple Stupid). The correct anesthetic is usually the simplest technique that works for the surgeon, the anesthesiologist, and for you. You get a vote. Use it, and choose wisely when alternatives are explained to you.
  7. If you have a family history of a blood relative who died under anesthesia, share this information with your anesthesiologist. The rare but serious malady Malignant Hyperthermia (MH) is an inherited disease which causes intense fevers, muscle rigidity, and hypermetabolism, and is triggered by specific anesthetic drugs such as sevoflurane, desflurane, isoflurane, or succinylcholine. The disease is rare (1 out of 100,000 anesthetics), but if your family has a history suggestive of MH, or if any of your family died under anesthesia, the anesthesiologist needs to know.
  8. You must stop eating and drinking prior to an elective anesthetic. The purpose is to keep your stomach empty at the induction of anesthesia. If you vomit or regurgitate stomach contents while you are unconscious, the food can be inhaled into your lungs, and you could acquire a serious pneumonia that could require an Intensive Care Unit stay, a prolonged hospitalization, or even loss of life. American Society of Anesthesiologists guidelines are nothing to eat after midnight the night before surgery, except clear liquids may be ingested up until 2 hours prior to surgery. Here’s an anecdote to relate how a patient can break this rule: Several years ago an anesthesiologist colleague of mine was scheduled to anesthetize a professional athlete for knee surgery. When this patient was asked if he’d followed the protocol and had nothing to eat or drink after midnight, the patient said yes, he had followed the rules. The surgery and anesthesia were performed without complication. In the post-anesthesia recovery room the patient boasted, “I knew it wouldn’t make any difference. I had bacon, eggs, and toast for breakfast this morning before surgery. I didn’t tell anyone because I knew it was a bogus rule.” It’s not a bogus rule. Don’t be like this local sports legend/difficult patient. Listen to the fasting rules and follow them.
  9. Sleep well the night before your surgery. For the majority of surgeries in the United States, a patient sleeps at home in their own bed the night before surgery. It’s rare to be sick enough to require inpatient admission to the hospital the day before surgery. Many patients are nervous regarding the impending anesthetic, and a wild array of thoughts and fears swirl through their brain regarding anesthesia and surgery. Many patients are too wired on their own adrenaline to sleep normally the evening prior to their surgery. What about sleeping pills? Are they safe the night prior to anesthesia? Yes, they are almost never unsafe. Common sleep medications such as Ambien, Ativan, or Valium taken at 10 pm won’t complicate the anesthetic course which begins 9 hours or more into the future on the following day. Because your anesthesiologist hasn’t personally met you and examined you, they cannot prescribe these medicines the night before for you. Your surgeon may prescribe sleep meds when he or she examines you. What about a glass of wine or an alcoholic beverage to aid sleepiness? Is this safe? Yes. If you’re an occasional wine drinker, there’s no serious harm to imbibing one glass of wine the night before surgery to help you relax and sleep.
  10. Trust your anesthesiologist as you would your airline pilot. When you board a commercial airplane, do you cast a glance into the cockpit to see what your pilots look like? I do. I’m reassured to see a touch of gray. It’s possible that a pilot in his or her 30s is outstanding, but the experience of a midcareer, gray-sideburned pilot is more reassuring to me. During your surgery you’ll be unconscious and unable to control your fate. You’re dependent on the anesthesiologist and his or her training and experience. The overwhelming majority of physician anesthesiologists are well trained and excellent. Calm yourself and trust your doctor.
  11. Read theanesthesiaconsultant.com as well as other reputable anesthesia sources on the Internet, such as the American Society of Anesthesiologists website, or Pubmed. Can you find misinformation on some healthcare websites? Yes. You’ll need to be careful regarding the source of your Internet education. But knowledge is a powerful tool, and I’d encourage you to expand your understanding of what anesthesiologists do to prepare for your upcoming surgery. Good luck!

12 MEDICAL INACCURACIES IN FAMOUS MOVIE SCENES . . . AN ANESTHESIOLOGIST’S ANALYSIS

I love the movies, but it can be painful to watch scenes where the facts are distorted, sometimes so much that the storyline is implausible. Let’s take a look at medical inaccuracies in movie scenes from 12 famous Hollywood films:

maxresdefault

  1. Million Dollar Baby (2004). This film is my Hollywood medical pet peeve, and the movie that motivated me to write this column. Million Dollar Baby won the Academy Award for Best Picture in 2004, yet the concluding scenes vital to the movie’s plot are both medically impossible and unrealistic. The female lead, Maggie Fitzgerald (Hilary Swank) is seriously injured in a $1 million World Boxing Association welterweight title match. Maggie is paralyzed from the neck down— a ventilator-dependent quadriplegic—and is hospitalized in a private room. Her coach and trainer, Frankie Dunn (Clint Eastwood) visits her. He sits next to her bedside and they discuss her fallen health. She tells Clint she doesn’t want to go on living like this, a paralyzed invalid. What’s the problem with this scene? It’s impossible for Maggie to talk if she’s on a ventilator. Maggie has a tracheotomy, with the breathing tube inserted in the front of her neck, below the level of the vocal cords. A patient cannot speak with a tracheotomy tube in place because all ventilation takes place below the vocal cords. If Maggie can’t speak, she can’t utter her lines, and she can’t partake in the dialogue with Clint. Somehow the movie’s medical consultants let the movie be filmed with this medical impossibility.                   But wait—there’s another medical impossibility. In a later scene, Clint returns to the same room and kills Maggie. First he turns off the ventilator and disconnects Maggie’s breathing hose at the tracheotomy site. Then he injects her IV with a syringe of adrenaline, and leaves the vital signs monitor on. The vital signs monitor shows her heart rate suddenly change to zero as she dies. That’s not how adrenaline works—it’s not a euthanizing drug. Adrenaline causes the heart rate and blood pressure to rise higher and higher—think heart rates in the range of 200 beats per minute and a blood pressure of 250/180. This may or may not kill someone over time, but it will not kill them in seconds. An injection of potassium chloride could kill Maggie in seconds, but where would Frankie obtain potassium chloride? He could not. As this scene ends, Frankie walks out of the room leaving Maggie to die behind him. The vital signs monitor continues to emit a soft high-pitched tone, but there’s no one else around to hear it. In reality the vital signs monitor would be emitting a loud alarm, signaling to everyone that the vital signs are gone and the patient is trying to die. These alarms would bring a fleet of nurses and/or doctors into the room to try to save the patient. But if they saved Maggie, Million Dollar Baby would’ve had a different ending, and Clint Eastwood wouldn’t have had his bold moment of stopping Maggie’s suffering—the bogus version of Million Dollar Baby that won Best Picture.

  1. Pulp Fiction (1994). In a famous scene Mia Wallace (Uma Thurman) snorts a large dose of heroin and collapses in either a cardiac arrest or a sudden coma. Vincent Vega (John Travolta) brings the unconscious Mia to his dealer’s house. The dealer hands Travolta a syringe of adrenaline connected to a 6-inch-long needle. Travola plunges the needle into the front of Mia’s chest with a prodigious swing of his arm. He doesn’t even have time to push the plunger and inject the adrenaline before Mia immediately screams and wakes up. This scene, as entertaining as it is, could never occur. No layperson would understand where in the body to inject intra-cardiac adrenaline. The chance of puncturing a lung or lacerating the heart or great vessels of the chest would be high. In a cardiac arrest the preferred route of epinephrine injection is into an arm vein, concurrent with chest compressions which move the drug through the circulatory system and into the heart. I’ve practiced acute care medicine for over three decades, and I’ve never found a need to inject epinephrine into a patient’s heart directly.                                                                                             And it’s unlikely Mia Wallace would wake up instantly. If her diagnosis was stupor from the combination of alcohol and heroin, then perhaps the pain of the injection would wake her. If she was suffering from a heroin/narcotic overdose, the specific antidote would be Narcan, not adrenaline, and it should be injected into one of her arm veins. If her diagnosis was a cardiac rhythm disorder such as ventricular fibrillation or ventricular fibrillation which caused sudden death, the only therapy likely to immediately revive her would be cardiac defibrillation, e.g. by an ACD (automatic cardiac defibrillator) similar to the machines found in public areas like airports or arenas. But if she had ventricular fibrillation or tachycardia for the entire duration it took to transport her across town to Travolta’s dealer’s house, then Mia would be dead after that prolonged time and she could never recover. Director/writer Quentin Tarantino scored bigger points by having his two biggest stars connect via a 6-inch needle to the chest. The result was memorable, laughable, and outrageous entertainment, but without plausibility.

  1. Casino Royale. (2006). James Bond realizes he’s consumed a poison drink while at a baccarat table in a casino. He knows he’s about to die, and stumbles to his car in the parking lot outside. He removes some sort of cell phone device from the glove compartment and contacts M’s headquarters in London. Bond instantly inserts a needle into his radial pulse at his wrist, and miraculously his vital signs are revealed to London. The doctor in London assesses that Bond is in ventricular tachycardia, a dangerous heart rhythm, and tells Bond to take the defibrillator out of the glove compartment and connect it to his chest. Within another minute, the electronic device inserted into Bond’s pulse miraculously transmits to London the diagnosis: the poison is digitalis. The doctor tells Bond to inject the blue syringe from the glove compartment to “counteract the digitalis.” (There is zero chance any spy would be carrying this rare antidote in his glove compartment) Bond blindly stabs himself in the neck with the syringe at a 90 degree angle, and then passes out before he can activate the defibrillator. Bond’s lady friend arrives on the scene in the nick of time and pushes the red button on the defibrillator to shock Bond, and he wakes up . . . all cured! None of this could happen.
    Let’s look at the series of medical impossibilities in this scene:
    It’s nearly impossible that in his stuporous state, Bond was able to insert a needle into a blood vessel. (No one inserts a needle into an arm vein without a tourniquet, so the vessel can’t be a vein. The blood vessel must be the radial artery. Also, no one inserts a needle into an arm vein at such an acute angle, so this argues for the vessel being an artery as well. In medicine, we do place catheters in the radial artery, but this takes significant skill as the vessel has an interior diameter of about 1 millimeter. We do send blood samples from a radial artery to a lab to diagnose blood levels, but the lab results take time to be processed. This is science fiction  that the touch of a needle into an artery would give an instant analysis of all blood levels, including diagnosis of a digitalis overdose.
    The continued impossibility is that the antidote for a digitalis overdose (A digitalis overdose antidote does exist, but the diagnosis is rare and so is this treatment) just happens to be one of the few syringes in the glove compartment in Bond’s car. The impossibilities continues in that Bond stabs the needle at 90 degrees into his right neck, magically finding a blood vessel there. The two blood vessels in the neck are the jugular vein and the carotid artery, and even the most experienced surgeon or anesthesiologists could not stab a needle into either of them in his own neck at a 90 degree angle without even aiming.
    That’s my analysis. An impossible scene, not medically researched, but it made for a James-Bond-level of entertainment.

    Somehow you had a feeling all along that Bond wouldn’t die, didn’t you? An academic medical paper examined the phenomenon of cardiac arrest survival rate in the movies. The article studied thirty-five cardiac arrest scenes in 32 movies from 2003 to 2012 (including Casino Royale, Mission Impossible 3, Inception, and Spider Man 3) for accuracy and credibility. (Ofole UM et al, Defibrillation in the movies: a missed opportunity for public health education, Resuscitation. 2014 Dec; 85(12): 1795–1798.) This medical study concluded that in the movies, defibrillation and cardiac arrest survival outcomes were often portrayed inaccurately. In 8 scenes of in-hospital cardiac arrest, 7 of the 8, or 88% of the patients survived, compared to survival rates of 23.9% reported in the medical literature. In 12 movie scenes involving out-of-hospital cardiac arrest, 8 of 12, or 67% of the patients survived, compared to survival rates of 7.9-9.5% reported in the medical literature. In summary, too many patients survived in the movies. I presume that’s because writers, directors, producers, and audiences all prefer to see their movie stars wake up and live. See #4 below for another example of the same in a blockbuster Hollywood movie.

breathinglife

  1. Jurassic Park (1993). Tim Murphy, the middle-school-aged grandson of the park’s inventor, is electrocuted on the perimeter fence of a dinosaur pen. He collapses to the ground and Dr. Alan Grant (Sam Neill) says, “He’s not breathing.” Dr. Grant proceeds to give Tim mouth-to-mouth resuscitation and chest compressions, and in exactly 26 seconds Tim coughs several times and wakes up. Remarkable! Per the medical publication in Resuscitation above, this sort of recovery from out-of-hospital cardiac arrest . . . only happens in the movies.

  1. Coma (1978). The 1977 novel Coma by Robin Cook, MD from Harvard was the first outstanding medical thriller, and one of the books that inspired me to become a writer. A successful movie version of Coma followed the book. The premise of Coma was that healthy young patients were developing brain death after general anesthesia, for no apparent reason. The protagonist Dr. Susan Wheeler (Genevieve Bujold) uncovers the root cause of the evil scheme: patients are breathing carbon monoxide instead of oxygen during general anesthesia, because some diabolical doctors have spliced a pipeline of carbon monoxide into the oxygen pipeline. The brain-dead patients are then harvested to a secret room and suspended by wires from the ceiling in a supine posture until their bodies can be sold and transported off as organ donors.                                                                                                                   In the 1970’s when the screenplay was written this plot may have seemed plausible, but in the 21st century it’s impossible. The anesthetic gases you breathe are now monitored on a second-to-second basis, and if the mixture does not contain adequate oxygen, multiple alarms sound off instantly. In addition, you wear a pulse oximeter on your fingertip. If the blood in your finger does not contain adequate oxygen, the oximeter reads a low result and alarms instantly so the anesthesiologist can remedy the situation. As well, extra oxygen tanks are present in every operating room as a safety back up, in the rare instance that the piped-in wall oxygen source is stopped or is inadequate. You can relax. Coma could not happen in this manner in the 21st

split2bmovie2bposter

  1. Split (2016). The villain in this film suffers from multiple personality disorder, or dissociative identity disorder (DID). In more than one scene, the villain Kevin Wendell Crumb (James McAvoy) sprays an aerosol into the face of his victims. Within seconds these individuals collapse in unconsciousness. Crumb lives and works at a zoo, where the audience is led to believe such a spray tranquilizer is used as needed to tranquilize the animals. As an anesthesiologist who induces unconsciousness in my patients every day, I can tell you that no such immediate coma-inducing spray gas exists. The potent inhaled anesthetics we anesthesiologists use are sevoflurane, desflurane, and isoflurane. Veterinarians these same anesthetic vapors for their surgical anesthetics as well. Each of these drugs is a liquid, which is then vaporized by special equipment to deliver inhaled anesthesia gas. These vaporizers are metal cylinders about the size of half-gallon milk carton. The fastest and most pleasant smelling of these vapors is sevoflurane. Inhaled sevoflurane can induce anesthesia in ten to thirty seconds if a high concentration of the drug is inhaled deeply into the lungs, but there is no drug that works in one second, like the aerosol that the villain used in Split.

  1. Old School (2003). This movie portrays another version of the instant sedative. In a scene at a youth birthday party, Frank Ricard (Will Farrell) picks up a tranquilizer gun which is designed to inject “the most powerful animal tranquilizer in the world” into any of the ponies or farm animals on display at the party. Frank accidentaly shoots himself in the neck, and the dart remains sticking out of the left side of his neck at a perpendicular angle. The owner of the gun, an animal tamer, comments that Frank has injected himself “in the jugular.” Within the next 30 seconds, Frank becomes increasingly wobbly and stuporous, and eventually falls face first into the swimming pool. Could this happen? Almost certainly not.                 Ketamine is the quickest injectable drug anesthesiologists have in their arsenal to anesthetize a patient by a non-intravenous injection. Ketamine is an injectable general anesthetic which is effective in inducing general anesthesia within 30-120 seconds after an intramuscular injection. If injected directly into a vein, e.g. an arm vein, ketamine can induce general anesthesia in 10-15 seconds. But the stab to Frank’s neck at the 90-degree perpendicular angle is unlikely to hit the exact location of the internal jugular vein, which is only about 1/2 an inch in diameter. And Will Farrell’s dart didn’t land in any big muscle like the buttock or the deltoid muscle at the shoulder, either. Powerful injectable animal tranquilizers such as etorphine or xylazine or tiletamine exist which can subdue a beast in a short time after intramuscular injection, but none of them will work as fast as the drug does in this scene. Movies are about entertainment, and it’s not entertaining to watch an actor spend five slow minutes becoming sedated enough to pass out so the plot can move onward.

  1. Awake (2007). Young billionaire Clay Beresford (Hayden Christensen, or Anakin Skywalker from the Star Wars movies) needs a heart transplant, and it turns out that he is awake and aware during the general anesthetic for his heart surgery. While he is awake he overhears the surgeon’s plan to murder him. Producer Joana Vicente told Variety that Awake “will do to surgery what Jaws did to swimming in the ocean.” The movie trailer aired a statement that states, “Every year 21 million people are put under anesthesia. One out of 700 remain awake.” Awake was not much of a commercial success, with a total box office of only $32 million, but the film did publicize the issue of intraoperative awareness under general anesthesia, a topic worth reviewing.                                                                                                              If you have a general anesthetic, do you have a 1 in 700 chance of being awake? If you’re a healthy patient undergoing routine surgery, the answer is no.  If you’re extremely sick and you’re having a high-risk procedure, the answer is yes. A key publication on this topic was the Sebel study. (The incidence of awareness during anesthesia: a multicenter United States study, Sebel, PS et al, Anest. Anal.  2004 Sep;99(3):833-9, Department of Anesthesiology, Emory University School of Medicine.) The Sebel study was a prospective, nonrandomized study, conducted on 20,000 patients at seven academic medical centers in the United States. Patients were scheduled for surgery under general anesthesia, and then interviewed in the postoperative recovery room and at least one week after anesthesia. A total of 25 awareness cases were identified, a 0.13% incidence, which approximates the 1 in 700 incidence quoted in the Awake movie trailer. Awareness was associated with increased American Society of Anesthesiologists (ASA) physical status, i.e. sicker patients.  Assuming that approximately 20 million anesthetics are administered in the United States annually, the authors postulated that approximately 26,000 cases of intraoperative awareness occur each year.                                                                         Healthy patients are at minimal risk for intraoperative awareness. Patients at higher risk for intraoperative awareness include: 1) patients with a history of substance abuse or chronic pain, 2) ASA Class 4 patients (patients with a severe systemic disease that is a constant threat to their life) and others with limited cardiovascular reserve, 3) patients with previous history of intraoperative awareness, 4) patients requiring the use neuromuscular paralyzing drugs during the anesthetic, and 5) patients undergoing certain surgical procedures which are higher risk for intraoperative awareness, including cardiac surgery, Cesarean sections under general anesthesia, trauma cases, or emergency cases.

vertigovertigo-dangling

  1. Vertigo (1958). Vertigo has no surgical/anesthetic/critical care gaffes, but I’ll comment on the film because the leading lady (Kim Novak) and I have the same last name (alas, we’re not related) and because it’s always been one of my favorite movies. The physical symptom known as vertigo is defined as, “a medical condition where a person feels as if they or the objects around them are moving when they are not. It often it feels like a spinning or swaying movement. This may be associated with nauseavomiting, sweating, or difficulties walking. It is typically worsened when the head is moved. Vertigo is the most common type of dizziness.In key scenes from Vertigo, Scottie Ferguson (Jimmie Stewart) suffers from attacks of acrophobia. His symptoms are presented as a whirling sensation when he looks downward from a height.                                                                                                           The symptom complex Jimmie Stewart suffers from in this movie would more accurately be described as acrophobia than vertigo. Acrophobia is “an extreme or irrational fear or phobia of heights, Acrophobia sufferers can experience a panic attack in high places and become too agitated to get themselves down safely.” Jimmie’s character is incapable of functioning at heights, and contributes to his inability to save Kim Novak from falling to her death in the film’s final minute. Vertigo is a catchy title—no doubt a more nuanced and debatable title than Acrophobia. In 2012 Sight & Sound granted Vertigo first place in their poll of the greatest films of all time. Imagine if the number one movie of all time had been correctly named Acrophobia after it’s medically accurate diagnosis.

  1. The Doctor (1991). In the movie’s opening scene, surgeon Jack MacKee (William Hurt) is shown in the operating room completing a heart surgery. As the final crucial stage of the operation is completed successfully, he asks for his “closing music.” The Jimmy Buffett song “Why Don’t We Get Drunk (And Screw)” begins to play, and the three male surgeons and the male anesthesiologist all sing the chorus together. William Hurt says to his scrub nurse, “Nancy, I want to hear you sing for me.” The photo above is the scene just before the singing begins. William Hurt is the surgeon, second from the right, and Nancy is on the far right. The anesthesiologist is in the center, in the immediate background. Why is this scene inaccurate? One answer is that the singing anesthesiologist is not separated from the sterile surgical field by the usual vertical barrier of sterile drapes known as the “ether screen.” Anesthesiologists don’t stand inches from the surgical field next to the surgeons. But how about singing the sexual song in the operating room? Many surgeons have their favorite closing music, and an occasional surgeon will sing along with their closing music. Could this scene of sexual harassment occur in 1991 when this movie was made? It could—back in the 1980s and 1990s I saw actions as bold as portrayed by William Hurt’s character, and worse. But this wouldn’t occur in 2017. There’s no tolerance for sexual harassment in the medical workplace nowadays.

11. Get Out (2017). An excellent thriller with absurd characters and shocking scenes, Get Out faltered badly regarding surgical and medical science. (Spoiler Alert) The plot hinges on brain transplantation, a far-fetched fiction in itself. To make the movie’s depiction even worse, the brain transplantations are performed in the basement of the neurosurgeon’s house, with the two patients side-by-side, and there is no anesthesia equipment or anesthesiologist. The first patient seems to be dozing, without any breathing tube or ventilator, while the surgeon (above) slices off the top of his skull. There are also no nurses or scrub techs, the only assistant being the neurosurgeon’s son, who is a medical student. An entertaining movie, right up until this scene, which is so absurd that no one could possibly believe it. Get Out received a Rotten Tomatoes score of 99%, so the critics (none of whom are doctors) still loved the movie.

12. The Outsiders (1983.) Francis Ford Coppola’s fine coming of age movie is marred by the improbable and impossible next-to-last scene where Johnny (Ralph Macchio) dies in his non-ICU hospital bed while his two friends Ponyboy (C. Thomas Howell) and Dally (Matt Dillon) watch him breath his last, and no one calls for a doctor or a nurse to help. In reality, a witnessed cardiac arrest in a hospitalized patient would lead to a Code Blue, with multiple doctors and nurses rushing into the room to treat the patient with a breathing tube, CPR, and intravenous Acute Cardiac Life Support medications.

There they are: my 12 favorite examples of medical inaccuracies from major film studios. Will there be more in the future? Don’t doubt it. Hollywood directors and writers aren’t likely to let mere medical science stand in the way of entertainment. 🙂

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

IS PRIVATE PRACTICE ANESTHESIA DOOMED?

THE ANESTHESIA CONSULTANT

What is the future of private practice anesthesiology?

ss-compensation-2017-overview-6008547

First off, let’s define “private practice.” The Merriam-Webster online dictionary defines private practice as: “a professional business (such as that of a lawyer or doctor) that is not controlled or paid for by the government or a larger company (such as a hospital).”

In my community the dentists are all in private practice, as are most of the accountants, psychologists, and attorneys. Why should anesthesiologists be any different? Let’s look at the issues.

A private practice single-specialty anesthesia group will usually provide anesthesia for similarly self-employed surgeons who are in private practice. How does the business work? When a single-specialty anesthesia group provides a service, the group decides the cost of that service, and the group sends a bill to the patient’s insurance company or to Medicare or Medicaid for that amount. How much will they get paid? It depends. Medicare and Medicaid cap their payments at a small fraction of an anesthesiologist’s typical fee. For insured patients, the anesthesia group collects whatever the insurance company pays, along with the deductible or co-pay the patient owes through their insurance plan. The collected amount, minus the group’s overhead (office employee salaries, office rent, office supplies, malpractice insurance, and health insurance for their own families) equals the anesthesia group’s profit.

A private practice anesthesia group needn’t be a physician-only group. In many private practice anesthesia groups, physician anesthesiologists supervise multiple nurse anesthetists in multiple operating rooms. These groups are still single specialty anesthesia groups. Physician anesthesiologists pay their nurse anesthetists as employees as well as their other expenses, and then divide the profit.

In recent years the prevalence of the private practice model is decreasing. The model is being replaced by jobs where the anesthesiologists are employees. Employees of whom?

One employee model is the multispecialty group model, in which all medical specialties work in parallel under one umbrella organization. Examples of this are the Permanente Medical Group (of Kaiser Permanente), Sutter Health in California, Mayo Clinic, and university groups such as Stanford Health Care in my neighborhood. The essence of this model is physicians are salaried, and income is divided amongst the different specialties. Surgical specialties such as anesthesiology and all surgeons earn less than they would in a self-employed private practice model, with some of the income from their services going to primary care specialists like family practitioners, internists, and pediatricians. It’s a symbiotic system since the referrals to the surgical specialists commonly originate from the primary care doctors in the first place. In this model an anesthesiologist will earn less money per case, but may increase his or her income by doing more cases.

A second employee model is the for-profit national physician corporation. The national corporation may purchase anesthesia private practice groups to gain access to their hospital and/or surgery center contracts. The corporation pays an up-front payment to the current anesthesiologists of each smaller group at the time of purchase. The parent corporation collects all future anesthesia bills, and pays out a decreased fee to the anesthesiologists who are now employees. The difference between the collected fee and the anesthesia pay-out equals the profit bottom line of the purchasing corporation, which may be a publically traded company.

A third employee model occurs when a single anesthesiologist or a smaller company attains an exclusive contract for a hospital or a surgery center. This solitary anesthesiologist or smaller company then employs other anesthesiologists at a lower set rate or salary, then contracts to have all billing and collecting done, and keeps the difference between the collected rate and the rate paid to the employees as profit.

One of the reason employee models are increasing in frequency is that the private practice of primary care medicine and the private practice of surgery are both shrinking. If more and more primary care doctors join large multispecialty groups or a national company, and if more and more surgeons join large multispecialty groups or a national company, there will be a paucity of patients for a freestanding anesthesia group to attend to. These trends are not going away.

As a result, today’s graduates from anesthesia residencies and fellowships are finding decreasing opportunities in true private practices, and increased offers to become someone’s employee. This means some of the anesthesia income will be shared with or siphoned off by other people.

Can young anesthesiologists do anything to reverse this trend? It depends. Private practice opportunities still exist in many geographic areas of the United States, if a new anesthesiologist is flexible about where he or she is willing to live. If you’re determined to stay in an overcrowded, underpaying marketplace, you may find nothing better than a salaried job at a modest income.

What is a modest income? Is $250,000 a year a modest income? That number sounds like a large income to most Americans. However if the doctor worked 60 hours per week and was awake all night performing anesthetics every fifth night, and if the collected fees for that individual’s anesthesia work that year totaled $750,000, then that individual was being paid significantly less than they earned.

How can you tell if your employer is paying you less than you earned? Find out what they are collecting per anesthesia unit of time, and do the math. Compare that number to what they are paying you. See my article on anesthesia billing as a reference for this.

Many private practice groups will survive. In the words of Charles Darwin, it will be survival of the fittest. Private practice groups will have to change and adapt to maximize their chances for survival. They will have to provide a higher level of service, and become more involved outside the operating room, in perioperative leadership, and in their local hospital politics and economics.

The anesthesia job market is part of the free marketplace in America, and Adam Smith’s invisible hand will drive individuals toward the best and highest paying opportunities. If you’re a young anesthesiologist, can you do anything to avoid the trend toward low salaried jobs? You can refuse to settle for poorly-paying jobs. Move to a marketplace that pays you well for your time. You may choose to not settle for a salary which is a mere fraction of what you are earning, especially if you are keeping patients alive at 3 a.m. while healthcare businessmen and stockholders are sleeping.

Medscape lists the best states for doctors to practice in. Flexibility in geography may yield a superior opportunity for you.

Medscape recently reported the average yearly income for anesthesiologists in the United States as $364,000. If your yearly income is $250,000 (this would be $114,000 under the average), then somewhere in the United States there are anesthesiologists with an income of $364,000 + $114,000 = $478,000, to maintain the average yearly income that Medscape reported.

When you input “private practice anesthesiologist” into Indeed.com, you’ll find multiple job offers. The private practice of anesthesia may be shrinking, but it’s far from gone.

PREANESTHESIA CLEARANCE: TWO QUESTIONS FOR PRIMARY CARE DOCTORS

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Many patients require preoperative clearance prior to surgery, especially patients with significant medical problems or at extremes of age. Preanesthesia evaluation reduces surgical and medical complications. What two questions for primary care doctors summarize the desired important information in preoperative surgical clearance?

1488514046161

Some health care systems run preoperative anesthesia clinics, where anesthesia professionals evaluate these patients prior to surgery. Such clinics can increase operating room efficiency and decrease day-of-surgery cancellations and delays, and are especially important prior to major inpatient surgeries such as brain surgeries, chest surgeries, abdominal surgeries and major transplants. In many health care systems there are no anesthesia clinics, and primary care doctors (internal medicine specialists, family practitioners, or pediatricians) do the preoperative assessments.

The surgeon may request the clearance or an anesthesiologist may request the clearance, but it will ultimately be the anesthesiologist who must care for the heart, lungs, brain, and blood pressure during the surgery and in the recovery room after the surgery.

Let’s choose an illustrative example. A 60-year-old man is scheduled to have a laparoscopic gallbladder removal (cholecystectomy). He takes lisinopril for hypertension and metformin for diabetes. He weighs 240 pounds, has a Body Mass Index of 38, and never exercises. What do anesthesiologists want to see in the internal medicine preoperative clearance consult?

We want to know the answer to two questions:

  1. Does the patient require any additional diagnostic workup prior to the surgery?
  2. Does the patient require any additional therapeutic changes prior to the surgery?

I’m Stanford-trained and board-certified in both internal medicine and anesthesiology, so I’m uniquely qualified to discuss this topic. Let’s look at what the process of an internal medicine preoperative consult looks like.

Let’s assume the internist has not seen the patient in the past year. The patient will be seen at the internist’s office, where the internist does a history and a physical, followed by an assessment and plan. The history includes a documentation of the past medical history, a review of current symptoms, a list of medications, allergies, past surgical history and family history. The physical exam includes the height, weight, vital signs, and documentation of any abnormal findings on exam of the entire body. The internist’s assessment will include a list of medical problems and a plan for each problem. For the patient above, the problem list would include:

  1. Hypertension
  2. Type 2 diabetes
  3. Obesity
  4. Sedentary lifestyle
  5. Preoperative assessment for upcoming general anesthesia for gallstones

An assessment and plan for each medical problem would be listed as follows:

  1. BP= 140/85 today. Plan: currently adequately controlled. Continue lisinopril.
  2. Plan: Check fasting glucose and hemoglobin A1c. Continue metformin.
  3. Plan: Weight loss counseling and consult with dietician.
  4. Sedentary Lifestyle. Plan: Advised initiation of exercise program.
  5. Preoperative assessment. Plan: cleared for general anesthesia providing ECG and labs are normal.

The labs are ordered, and the results accompany the history and physical. All the lab tests are normal. The ECG is abnormal, and shows diffuse ST wave abnormalities suspicious for ischemia (inadequate blood flow to the heart muscle). At this point the primary care physician can answer the two questions above:

  1. Does the patient require any additional diagnostic workup prior to the surgery? Answer: Yes. The patient requires referral to a cardiologist for workup of the abnormal ECG, especially in context of his sedentary lifestyle and risk factors of hypertension and diabetes.
  2. Does the patient require any additional therapeutic changes prior to the surgery? Answer: Dependent on the cardiologist’s assessment.

The surgery is delayed pending the cardiologist assessment. The cardiologist sees the patient, and recommends an exercise stress echocardiographic. The test is done, and is abnormal—the patient has abnormal decreased movement of the left anterior wall of his heart with exercise. Because of this abnormality, the cardiologist recommends a cardiac catheterization. The cardiac cath is done, and the patient has a 90% narrowing of his left anterior descending coronary artery. The cardiologist places a stent across this narrowing, and the patient is discharged home.

Because of the primary care doctor’s work, the patient had the necessary diagnostic tests done (blood work, ECG, and referral to cardiology), and the patient had a necessary therapeutic intervention done (a coronary stent). The gall bladder surgery is scheduled for one month hence.

Let’s discuss what a primary care doctor’s not should NOT be. The primary care doctor should not recommend what form of anesthesia is safe, e.g. “medically cleared for spinal anesthesia,” or “medically cleared for local anesthesia plus sedation.,” or “medically cleared for regional block anesthesia.” The primary care doctor should not recommend what drugs are safe to use. The primary care doctor should not recommend where the surgery should or should not be done, e.g. in a hospital, a surgery center, or in a doctor’s office. The primary care doctor should not estimate the percentage of survival or morbidity for the scheduled procedure.

Primary care doctors are very smart and highly trained professionals, but primary care doctors don’t work in operating rooms. They don’t know which anesthetic technique to recommend, which drugs to utilize, or the different strengths and weaknesses of different anesthetizing locations. What they do know is the outpatient condition of their patient.

Anesthesiologists need the answers to #1 and #2 above. If you’re an anesthesiologist, you now know exactly what questions to ask. If you’re a patient about to undergo surgery, you now know how important the preoperative medical assessment is to your anesthesiologist.

The National Football League (NFL) of American football is a multibillion-dollar industry which dominates the sports airwaves and press headlines from the first preseason game each August until the Super Bowl each February. Do you know the intersection between an anesthesiologist and the NFL? On January 3rd, 2023, Buffalo Bills safety Damar Hamlin 24 suffered a cardiac arrest mid-game when he collapsed after a helmet to his sternum tackle against the Cincinnati Bengals. Hamlin received CPR on the field, and his heartbeat was restored before he was taken to a Cincinnati hospital. Was there an anesthesiologist involved in Damar Hamlin’s resuscitation? Almost certainly.

At each and every NFL game there must be one Airway Management Physician on the sideline. This Airway Management Physician is most commonly an anesthesiologist or an emergency medicine physician. My anesthesia company had the contract for the San Francisco 49ers Airway Management Physician during the 2005-2006 season, and I worked in this role. It was a fascinating job, and in this column I’ll fill you in on the experience.

Why must every NFL game have an Airway Management Physician on the field? Football is a violent sport played by young men of unprecedented speed and size. When these men collide there is always the risk of injury. The NFL Physicians Society (NFLPS) mandates a 27-person game-day medical staff.

nflhealthcarechart

Each sideline includes 2 orthopedists, 2 primary care physicians, 4 athletic trainers, 1 unaffiliated neurotrauma consultant, and 1 chiropractor. In addition, the Stadium Medical Team includes 1 dentist, 1 ophthalmologist, 1 Airway Management Physician, 2 Emergency Medical Technicians, 2 independent athletic trainers, 1 radiology technician, and 1 visiting team medical liaison.

During the game, common football injuries to the knee, ankle, foot, shoulder, elbow, or hand are matters for the team orthopedic specialists, the athletic trainers, and perhaps the chiropractor. Injuries to the head activate a concussion protocol in which the neurological examination is carried out with the aid of the neurotrauma consultant.

The Airway Management Physician is present in case of a severe medical complication. This would include a cardiac arrest, a respiratory arrest, a cervical spine injury, or an airway injury which impairs breathing. In these situations the acute medical management must follow the standard sequence of Airway, Breathing, and Circulation. The player’s airway must be open and secured prior to any effective breathing or cardiac care. If the player’s airway is not open, the Airway Management Physician is responsible for placing a breathing tube through the player’s mouth into his windpipe so oxygen can be effectively ventilated in and out of the lungs. The absence of oxygen to a patient’s brain for 3-5 minutes can cause permanent brain damage.

The NFL game day Airway Management Physician will be an experienced anesthesiologist or emergency room doctor, because these are the two specialties which deal with the placement of urgent breathing tubes in hospital operating rooms, emergency rooms, or intensive care units.

The urgent placement of an airway tube is called a Rapid Sequence Intubation, or RSI. Anesthesiologists routinely use RSI technique to place a breathing tube into a patient’s windpipe prior to emergency surgery. Emergency surgery patients are always classified as “full stomach” patients, meaning that they have not fasted for the required 8 hours prior to elective surgery. Patients who have full stomachs are at risk for vomiting their stomach contents into their lungs. This can be a lethal complication. In my 30+-year career as an anesthesia attending, I’ve placed thousands of RSI breathing tubes prior to surgeries. Emergency room physicians place RSI breathing tubes for various causes including trauma, cardiac arrests, or respiratory arrests.

To perform a RSI, the anesthesiologist or emergency room doctor will administer a hypnotic drug (such as propofol or ketamine) if the patient is conscious, followed by a paralyzing drug (such as succinylcholine or rocuronium). At the same time, a medical colleague (a surgeon or a nurse) will press down on the cricoid cartilage at the anterior aspect of the patient’s voice box. This is called a Sellick maneuver or cricoid pressure, and this serves to compress cricoid cartilage (which circles the windpipe) downward against the esophagus to reduce the chance of stomach contents regurgitating into the mouth and/or lungs.

Next the anesthesiologist or emergency room doctor inserts a lighted instrument called a laryngoscope into the patient’s mouth, to identify and visualize the opening to the trachea or windpipe. The physician then inserts a hollow plastic breathing tube called an endotracheal tube (ET tube) into the windpipe. The ET tube has an inflatable balloon near its tip. Once the ET tube is in place, the physician inflates the balloon to secure a tight fit within the windpipe. Oxygen can then be ventilated in and out of the tube via a breathing bag.

A RSI is a stressful acute medical procedure in which there is little room or time for error. If the physician has difficulty inserting the breathing tube and the patient has no oxygen entry, the patient can suffer anoxic brain damage within 3-5 minutes. In a hospital setting, even when the physician has all the necessary equipment at his or her fingertips, a RSI can be a harrowing experience. Trying to execute a RSI on the 50-yard-line of a football field, on a 300-pound athlete with a thick neck and who is wearing bulky shoulder pads and perhaps a football helmet, under national television audience scrutiny, would be stressful to the extreme.

No NFL player to date has ever had a cardiac or respiratory arrest on the football field during a game. On August 20th, 2005, San Francisco 49ers offensive lineman Thomas Herrion collapsed and died the locker room after a preseason game in Denver. Per a personal account from a physician present in the locker room at the time, the team had gathered around and closed their eyes to say the Lord’s Prayer, and during that prayer they heard a loud thump. They opened their eyes to see Herrion lying on the ground unconscious and seizing. No anesthesiologist or emergency room physician was present. The physicians who were present attempted to revive Herrion. He was transported to St. Anthony’s Central Hospital where he was pronounced dead.

Per coroner Amy Martin, a forensic pathologist in Denver, Herrion weighed 335 pounds and was 6 feet 3 inches tall. His autopsy was positive for significant blockage of the right coronary artery, and his cause of death was listed as heart disease. His blood tests were negative for any steroids or performance-enhancing drugs. He entered the game for about 20 plays near the end of the game, and he appeared to be in normal physical condition prior to entering the locker room.

In the weeks following Herrion’s death, my anesthesia company was hired to be the Airway Management Physicians for the remainder of that 49ers season. I was the Airway Management Physician for the September 25, 2005 game between the 49ers and the Dallas Cowboys at Candlestick Park in San Francisco. Prior to the game we dressed in team medical polo shirts in the team locker room with the other members of the medical team. Some physicians were engaged in pregame consultations with the trainers regarding players with injuries or ailments. Before the game I joined a group of physicians who walked to the opposing sideline to introduce ourselves to members of the Cowboys medical team. Just prior to kickoff, when the 49ers ran out of their locker room onto the field, we physicians walked just behind them. The soundtrack to our stadium entrance was the same roaring ovation that the sellout crowd gave their football heroes—it was an unforgettable experience.

I was given a small, 10 X 4 X 4-inch pouch labeled “RSI equipment.” Inside were the necessary items: the laryngoscope, the syringes, and the drugs necessary for a routine Rapid Sequence Intubation. I must confess that for multiple reasons I was praying I would not intubating a 335-pound lineman with the contents of that pouch on that day. Along with the other members of the medical team, I was instructed to remain between the 30-yard-line and the goal line on either end of the field, and not to enter the team bench area between the 30-yard-lines. I was given a red hat to wear so I could be easily identified in an emergency situation. I remained in the immediate vicinity of the other team doctors so I was ready for a team approach should an emergency occur. I watched the game vigilantly so I would be ready should an emergency occur.

There were no cardiac arrests or fractured cervical spines, and my services were not required on that Sunday. Following that season the 49ers contracted with the full-time faculty of Stanford Medical Center to be their Airway Management Physicians, and I never had the opportunity to reprise the experience of that one 49ers-Dallas game.

I was left with several lasting impressions regarding the NFL anesthesiologist experience:

  1. The sheer size of the linemen makes their airways potentially difficult to manage. I performed anesthetics on multiple San Francisco 49ers players for orthopedic surgeries over 15 years time. Their cardiovascular fitness was never in question, but their bulk was striking. A Body Mass Index (BMI) table states that a 335 pound, 6 foot 3 inch patient has a BMI=41. A BMI over 40 is defined as Morbid Obesity, and this is always a significant anesthesia concern. Morbid Obesity carries a risk classification of American Society of Anesthesiologists Class 3, which is defined as “a patient with a severe medical disease which is currently stable.” A professional athlete is more healthy than an inactive couch potato fan who watches the NFL on television, but nonetheless anesthetizing gigantic men requires skill and entails risk.
  2. A second lasting impression is that the RSI pouch I was given in 2005 would be woefully inadequate in 2017. An essential tool to intubate a 300-pound giant wearing football gear is a portable video laryngoscope, such as the McGrath 5: hqdefaultThis is a handheld tool with a camera on one end and a video screen on the other. The video laryngoscope allows the physician to see around the curves of a large man’s tongue and jaw, and to visualize the opening to the windpipe without moving or extending the cervical spine (which in some football injuries must be suspected of having an unstable fracture). I’m certain that modern day RSI equipment at NFL games includes not only a portable videoscope but also a larger array of breathing tubes and airway management tools such as you’d find in a difficult airway cart in an operating room or an emergency room. The American Society of Anesthesiologists Difficult Airway Algorithm references the optimal approach to any airway difficulty, and an airway emergency on an NFL playing field would be best managed per this Algorithm.
  3. My third profound recollection is how memorable it was to be on the sideline for an NFL game, and how memorable it was to witness the spectacle up close. My own football skills never advanced past 3-on-3 touch football, but I’m a fan, and I’ll always remember my adventure as a member of the medical team for America’s number one sports attraction.

As of January 4th, 2023, our thoughts and prayers are with Damar Hamlin and his family, with the hopes that the NFL’s preparation for acute cardiac arrest injuries proves successful in his case.

THE ANESTHESIA CONSULTANT

I want to thank my readers, as theanesthesiaconsult.com reached 1,000,000 views this week.

img_5705

The website was born in 2010 when I posted multiple columns I originally wrote for the Stanford Anesthesia Department publication The Gas Pipeline. Over the following months I added a series of columns aimed at laypeople, answering frequently asked questions about anesthesia.

The website reached only a few thousand viewers the first year, but I kept writing and the readership grew. By 2017 the number of columns grew to the current total of 148 pages. The crescendo in traffic was progressive, with a recent boom to a level of approximately 11,000 views per week, and a pace to reach over 500,000 readers per year. Thirty-five percent of the clicks are on columns aimed at anesthesia/medical professionals, and 67% of the clicks are on columns aimed at the public. My readers reside in over 100 countries from around the world.

The website has been an adventure for me. I write and control everything as a one-man production. The platform is a WordPress.com template, and my only expense is $18 per year to WordPress for website hosting. I’ve never paid a penny for Internet search engine optimization, or for efforts to rise toward the top on Google search lists.

I enjoy corresponding with readers, and I frequently write columns in response to a request or question from a reader. In addition to writing about my own experience and training, I rely heavily on Pubmed.com as my source of knowledge of the peer-reviewed medical literature, which I frequently summarize and refer to for my readers.

Three sets of editors have contacted me to write chapters for their anesthesia/surgical textbooks on topics I’ve written about on my website. A leading university anesthesia program invited me to travel to their hospital and lecture as a Visiting Professor. Attorneys from 20 states have contacted me for opinions on legal cases.

Writing is a passion, but my primary job is still clinical anesthesia. I attend to patients before, during, and after surgery, five days a week. I’ve personally administered more than 25,000 anesthetics over 33 years, and have no plans to retire soon.

The success of theanesthesiaconsultant.com would not be possible without my readers, and I thank you all. I’ll keep writing, and I invite you to keep reading.

Thanks a million!

Rick Novak, MD

Dr. John Brock-Utne’s Clinical Research, Case Studies of Successes and Failures is a unique and valuable addition to the medical literature, and a must-have handbook for medical school faculty members of all ages and seniority.

Dr. Brock-Utne is a Professor of Anesthesiology, Perioperative and Pain Medicine at Stanford University, and an experienced and accomplished academician. His book is a treatise on how to create significant clinical research studies, and how to get those studies published.

Faculty members in academic medical centers have long been evaluated by a “Publish or Perish” mentality. Publishing significant papers in prominent medical journals is expected if a faculty member wants to solidify his or her job security, or to gain tenure at a university.

A Google search for “Clinical research guidebooks” reveals a paucity of competing books. Brock-Utne’s Clinical Research, Case Studies of Successes and Failures is to date the only manual written by a medical professor for this purpose. Just as many prominent business and law schools teach by the case study method, Brock-Utne follows the same technique. Each book chapter presents a question regarding clinical research, posed in Socratic manner, based on the author’s actual experience,. A discussion of the answer follows. This format makes for easy and thoughtful reading, and effective assimilation of the desired knowledge.

Dr. Brock-Utne speaks from experience. A PubMed search documents that he has 271 publications to date, spanning 46 years from 1971-2017.

The three appendixes at the conclusion of the book sum up the major content in concise form. Appendix A (Review of the Clinical Research Process From Beginning to End), Appendix B (The Future of Clinical Research), and Appendix C (Summary Pearls) deserve reading and rereading until the pages are dog-eared.

This book is an essential addition to the library of faculty members of any department or medical specialty. The future of medicine requires the grooming of well-informed, talented researchers. Hopeful researchers need a how-to guide of the outstanding caliber of John Brock-Utne’s Clinical Research, Case Studies of Successes and Failures.

12 TIPS ON BECOMING AN OUTSTANDING ANESTHESIOLOGIST

THE ANESTHESIA CONSULTANT

What qualities define an outstanding anesthesiologist? The bell-shaped normal curve describes the random distribution of many things. A bell-shaped curve exists for the abilities of anesthesia doctors as well.

Print

 

 

I’ve been practicing anesthesia since the mid 1980s. I’ve met and worked alongside hundreds of anesthesia colleagues from all corners of the globe. Some were academic professors, some were trainees at a university, and some were community anesthesiologists either in my group or in other anesthesia companies.

We’re entering an era of metrics for physicians, in which the government and hospital systems will collect data to monitor quality and performance. Because the outcomes of most surgical anesthetics are overwhelmingly uneventful, the occurrence of negative metrics for anesthesia performance will be rare—too rare to quantitate whether one doctor is “better” than another.

Rather, I’m choosing to list the qualities I’ve witnessed that make physician anesthesiologists stand out as leaders.

To be an outstanding anesthesiologist, you must:

  1. Be smarter than other anesthesiologists. Certain anesthesiologists pride themselves on keeping up with the new developments in medicine. They also repeatedly review the essential knowledge base they learned as a trainee. Their pursuit of knowledge is multifaceted, and includes reading journals, attending lectures, attending conferences, and habitually reading textbooks, Pubmed, or Internet searches when they see an opportunity to learn. Interaction with other smart anesthesiologists is essential. I’ve seen instances where an isolated company of anesthesiologists tells themselves, “We are the best anesthesiologists,” when they rarely interact with the anesthesia world outside their group. This can be a vain conceit. Only by engaging the greater community of anesthesiologists outside your tiny geographic domain can you exchange information and grow as a doctor.
  2. Be prepared. The Boy Scouts of America motto is “Be Prepared.” Anesthesiologists must abide by the same value, because an anesthesia complication that goes sour can cost a patient’s life within minutes. Every anesthetic is an opportunity to care for a patient at the highest level, and an opportunity to err. Planning anesthesia care, based on your training, experience, and knowledge, is critical. You also need to be ready to manage a difficult airway, hypotension, hypertension, or the myriad of acute respiratory and cardiac complications that can occur before, during, or after a surgical anesthetic. Pay attention at every Quality Assurance meeting, every Mortality and Morbidity conference, and to every tale of a near-miss anesthesia calamity. Remember the circumstances of other doctors’ complications, and utilize the information to be a safer doctor yourself.
  3. Be friendly and personable. You have to get along well with surgeons, the nursing staff, the scrub techs, administrators, and the patients. If your medical colleagues look forward to working with you because you’re a pleasant individual with a positive attitude, this bodes well. If your medical colleagues find you brash, moody, or easily angered, the opposite is true. Anesthesiologists aren’t typically known to be verbose. A pathologist friend of mine, commenting on the lack of verbal skills in his profession, one said, “The extroverted pathologist looks at your shoes instead of his own shoes when he talks to you.” Don’t be like that pathologist. Polish your interpersonal skills.
  4. Learn how to wake up patients promptly. It sounds elementary, but I still see mid-career anesthesiologists whose patients take too long to wake up. Their patients are obtunded on arrival to the Post Anesthesia Care Unit (PACU) after surgery, and they rely on the PACU nursing staff to complete the job of anesthesia wake up. Surgeons, nurses, and other anesthesiologists notice this, and the reputation of a practitioner who can’t wake a patient on time is no secret within a surgical suite.
  5. Learn to perform medical procedures at the highest level. Anesthesiologists are hands-on doctors. We earn our living placing breathing tubes, IVs, arterial lines, central lines, epidural catheters, spinal blocks, and ultrasound-guided regional blocks. Some anesthesiologists are wizards with their hands. Some are not. Reputations are built and lost based on the manual skills of physician anesthesiologists. The nurses, surgeons, and techs know which anesthesiologists to recommend, and they won’t recommend you if you’re inept.
  6. Enjoy your 10 minutes with each patient prior to surgery. The preoperative evaluation is a medical interview to review the history, physical examination, and laboratory tests, and the evaluation is followed by a discussion of the anesthetic alternatives and risks—but those 10 minutes are much more than that. It’s your chance to get to know this person you’re about to render unconscious. You have an opportunity to converse about their heritage, the geographical course of their life to date, or their hobbies. The patient wants to like you and trust you, because you’re about to take his or her life into your hands. Take the time to connect with your patient before the anesthetic, and you won’t regret it. In our anesthesia company’s practice, we MDs have always inserted our own preoperative IVs. This gives us more face time with the patient to converse with them and comfort them, and perhaps make them laugh prior to rendering them unconscious. Many hospitals and surgical centers prefer to have an RN place the preoperative IVs. This may save 3-5 minutes of time. I’m all for efficiency, but this time is better spent with the doctor applying his or her skills at IV insertion while chatting and putting the patient at ease.
  7. Avoid letting surgeons boss you around. Many surgeons are excellent co-professionals to work with, and some are not. Some surgeons are bullies, and are condescending in their remarks and attitudes toward the anesthesia provider they’re working with. I implore you to never submit to this abuse. The most important value in the operating room is to care for the patient, but this value is never best served with a surgeon intimidating the operating room staff. Stick up for yourself. Stick up for the circulating nurse and the scrub tech as well, if necessary. In the long run this will result in excellent care for more patients. The other medical professionals in the operating room will respect you for it.
  8. Cultivate your speaking and writing skills. It’s difficult to rise among the ranks of your fellow physicians unless you’re a superior communicator. Speaking skills are essential in every doctor-patient conversation. You’re selling yourself to the patient and their family as a confident practitioner. They’re nervous, they’ve never met you, and they’re forming their first impression of the individual who will soon be responsible for keeping them alive. Your abilities to communicate with surgeons, nurses, and techs before, during, and after a surgical anesthetic are also important. To rise to leadership roles, you must eventually speak at committee meetings, clinical conferences, administrative meetings, and possible at community, county, or state level medical meetings. Likewise, the ability to express yourself via the written word is critical. Some physicians will find themselves authoring peer-reviewed publications in scientific journals or chapters in textbooks. Others will author columns or opinion pieces in hospital, community, county, or state newsletters. Even routine communications via email are opportunities to produce eloquent, well-organized thoughts to your medical colleagues.
  9. Avoid being a “locker-slammer.” In anesthesia jargon, a locker-slammer is a practitioner who finishes his or her day of operating room anesthetics, goes directly to the locker room, changes out of his or her scrubs, slams the locker shut, and goes home. A locker-slammer will shun hospital politics, meetings, and out-of-the-operating room medical interactions. A true locker-slammer may practice at a given hospital for years and be unknown to anyone outside of the operating room suites. To avoid this fate, get involved. Anesthesiologists are vital on hospital committees such as the Quality Assurance Committee, Pharmacy Committee, Critical Care Committee, Emergency Room Committee, Medical Executive Committee, and many more.
  10. Trust your gut, and choose a line of work you love. The saying goes, “If you love what you do, you’ll never work a day in your life.” Outstanding anesthesiologists love their career. If you don’t love managing Airway, Breathing, and Circulation in surgical patients at all hours of the night and day, perhaps you’ve chosen the wrong specialty.
  11. Avoid complaining about long days or short days in the operating room. In my first year of private practice I used to moan about days with little or no work, because I wasn’t making any income that day. Two days later I’d have a 30-hour shift where I was working constantly without sleep, and I’d grouse about that. A senior anesthesiologist took me aside and said, “Richard, don’t complain about the short days. Get out there and enjoy your free time. And don’t complain about the long days. Those are the days you’re making money, and be happy about that fact, too.” He was right, and I share his advice with you as well.
  12. Understand the economics of anesthesia practice, billing, and reimbursement. I knew very little about these topics when I finished my residency training. Graduating residents in the 21st Century still know very little about these topics, which puts them at high risk to accepting low-paying jobs with little upside for leadership. Anesthesiologists earn solid money, but different job descriptions pay markedly different wages. Shop around. Attend the American Society of Anesthesiologists Practice Management Conference. If you’re ambitious, why would you take a job as a 40-hour per week employee for a large corporation, if that corporation is billing high fees for your service and then paying you 50% of what they collect? Physician anesthesia leaders must become skilled businessmen and businesswomen as well as clinicians.

These are a dozen traits I see in outstanding anesthesia colleagues. How many of these traits do you have? If there are traits you lack, I hope this column inspires you to gain them. Be patient with yourself. A career in anesthesia is a marathon, and these 12 tips are guideposts for your journey.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

THE CHILD WITH AN OPEN EYE INJURY AND A FULL STOMACH

THE ANESTHESIA CONSULTANT

A 3-year-old boy is eating a McDonalds Happy Meal on the lawn of the restaurant. A lawn mower approaches, and a rock is ejected from the mower, hitting the child in the eye. The boy suffers a penetrating open eye injury, and is taken to the nearest hospital. You are on call for the repair. You’re are an experienced practitioner, but not a pediatric anesthesia specialist. What do you do?

38ff4

Discussion: There are two issues. One is how to safely perform the open-eye, full stomach anesthetic, and the other is the performance of pediatric anesthesia by non-pediatric anesthesia specialists.

Your goals for this anesthetic are to protect the airway and to avoid increases in intraocular pressure (IOP). Sudden increases in IOP in patients with an open globe injury can lead to vitreous loss and blindness. The list of things that increase IOP and risk further eye damage includes crying, coughing, the Valsalva maneuver, vomiting, firm pressure with an anesthesia face mask, laryngoscopy, and endotracheal intubation. Ketamine and succinylcholine also increase IOP. Trying to start an IV without causing crying and the attendant increase in IOP in a 3-year-old can be difficult.

True ophthalmic emergencies (e.g. central retinal artery occlusions or chemical burns) must be treated within minutes to avoid blindness or permanent vision loss. A penetrating open globe injury is usually urgent, rather than emergent. At times urgent procedures are delayed until the patient has been fasting for 6 hours, and has an appropriate NPO status.

Let’s assume your surgeon is determined to operate urgently, and doesn’t want to wait 6 hours after the patient’s meal. In his judgment delaying the surgery would increase the patient’s risk of loss of vision.

No single approach to this patient is ideal, but a proposed approach is:

  1. Apply EMLA cream with an occlusive dressing over several potential IV sites 45-60 minutes before the IV attempt. Next give the boy an oral midazolam premedication (0.67 mg/kg), and wait until he becomes sedated enough to start an intravenous line.
  2. Once the IV is in place, a modified rapid sequence induction is done with cricoid pressure, using rocuronium as the muscle relaxant. A dose of 1-1.5 mg/kg is used to speed the pace of neuromuscular blockade. With the availability of sugammadex to reverse deep rocuronium motor block, the risks of a high dose of rocuronium in this setting are minimal. A nerve stimulator is used to confirm that depth of muscled blockade is adequate, to avoid any coughing during laryngoscopy. The FDA black box warning regarding pediatric use of succinylcholine allows for its use for emergency intubation or for patients with a full stomach, but this author prefers to avoid it if alternatives exist. Succinylcholine causes a transient tonic increase (4-20 minutes) in extraocular muscle tone, which causes an increase in IOP of 10 to 20 mm Hg.
  3. If the child has chubby arms, hands, ankles and feet, and you are not able to place the IV despite adequate oral sedation, you may proceed with an inhalation induction. Utilize sevoflurane with cricoid pressure maintained throughout. Once the child is asleep, the IV can be placed, relaxant given, and the endotracheal tube inserted.
  4. An oral gastric tube is used to suction out the stomach.
  5. Controlled ventilation is recommended, to insure the field is quiet for the surgeon.
  6. At the conclusion of surgery, because of the full stomach, the patient is extubated awake. For tips on a smooth emergence, see my column on Smooth Emergence from Anesthesia.
  7. Postoperative nausea and vomiting can increase IOP. Prophylactic IV ondansetron is recommended.
  8. Postoperatively, a pain-free child will cry less and have fewer increases in IOP. The surgeon should consider a regional block of the eye to decrease the need for postoperative narcotics.

The second issue in this case is that you’re not a pediatric anesthesiologist. A children’s hospital or a university hospital will have a team of pediatric anesthesiologists with specialized training on call for emergencies. Call schedules and staffing are different in community hospitals, where a smaller team of anesthesiologists shares night call. Unless the hospital is very large, it’s uncommon to have anesthesiologists of multiple specialties on call each day, e.g. one for pediatrics, one for cardiac cases, one for trauma, one for obstetrics, and one for the general operating rooms. It’s common for general anesthesia practitioners to cover many or all specialties when they’re on call. If the on-call anesthesiologist is not comfortable with an individual case, he or she can seek out and call in a better-trained anesthesiologist, if one is available. The goal of producing a specialist anesthesiologist for every type of case at all hours of the night and weekend is a difficult one to staff. The decision to care for this patient at a community hospital at all is a judgment as to whether standards of care can be met with the physicians who are available. I’m double-boarded in internal medicine and anesthesiology, and have no extra post-graduate training in pediatric anesthesia, yet I have cared for children age 10 months and over for over 30 years. I consider myself expert and confident in the anesthesia care of children of these ages in a community setting.

In my opinion, neonates and younger infants need anesthesiologists with specialized pediatric training. Whether specialized training should be mandated when anesthesiologists care for older children is debatable. Policies to define a minimum age limit for patients of general anesthesiologists may be a hot topic in the future.

Their book contains a series of chapters designed to teach the anesthesia professional how to perform our craft at a higher level. There are alternate textbooks, e.g. Miller’s Anesthesia, which contain an encyclopedic knowledge of our specialty, but the new Larson and Jaffe book will teach you how to improve and enhance your patient care. Between them, Larson and Jaffe have supervised tens of thousands of anesthetics in a university practice. Between them, Larson and Jaffe have taught hundreds of anesthesia residents the finer points of clinical care. Now, because of this book, readers can find on the printed page what the authors taught in the preoperative forum, in the operating room, and in the post-anesthesia recovery room.

The authors clearly state the philosophy of the book in the Preface: “As a result of the importance given to evidence-based anesthesia, practices based on experience or common sense are suspect and often denigrated. Further, some clinical practices do not lend themselves to scientific validation, as examples in this textbook will show. This is where the art of anesthesia plays an important role in maintaining the highest quality of anesthetic care. This book is not intended to be a comprehensive textbook of anesthesiology. Rather, we have selected key topics in the specialty where we believe the art of anesthesiology has generally been overlooked, misunderstood, or forgotten.”

Representative chapter titles include: Role of the Laryngeal Mask Airway in Airway Management, Essentials of Airway Management, Laryngospasm: the Silent Menace, Cricothyrotomy: A Lesson to Be Learned, Nitrous Oxide: Yea or Nay, Meperidine: A Forgotten Jewel, Sevoflurane: The Most Versatile Anesthetic Ever Developed, and The Bariatric Challenge.

Dr. Larson was the Chairman of Anesthesia at Stanford during the 1980’s, and the Editor-In-Chief of Anesthesiology, the world’s foremost anesthesia journal, during that same time period. He was my neuroanesthesia professor at Stanford. I was fortunate enough to spend hundreds of hours with him, learning the craft of anesthesia from a true legend. He loved to teach during the maintenance phase of a surgical case, and always utilized the Socratic method. He’d say, “The intake valve on your anesthesia machine is stuck in the open position. What’s the worst thing that could happen?” Then he’d stare at me while the gears churned in my head, as I searched and searched for the answer to a question I’d never considered. Dr. Larson also taught residents his hands-on method for awake intubation. He’d utilize this technique on all patients scheduled for lumbar disc surgeries: We’d sedate the patient, perform an awake oral fiberoptic intubation, and then have the patient roll themselves over into the prone position while awake, with the endotracheal tube already in their trachea! It was a remarkable technique, and representative of the pearls of wisdom present in this new textbook.

Dr. Jaffe is a Professor of Anesthesia at Stanford, and the lead author of Anesthesiologist’s Manual of Surgical Procedures. Next to Miller’s Anesthesia, the Anesthesiologist’s Manual of Surgical Procedures is the most essential textbook for any anesthesia trainee. At first glance, Jaffe’s first book appears to be a “cookbook” which gives recipes for nearly every anesthetic procedure, but it is much more. The textbook includes both the surgical and the anesthetic details for all common surgical procedures anesthesiologists will face.

Together, Drs. Larson and Jaffe own decades of anesthesia wisdom. The new compilation of their knowledge, Practical Anesthetic Management—The Art of Anesthesiology, is a must-have for the library of every anesthesia teaching program in the world, and is highly recommended for every resident, fellow, and practitioner of the art of anesthesia as well.

May the force, and the art, of anesthesia be with you.

THE ANESTHESIA CONSULTANT

I commonly hear two questions from my patients: “How does anesthesia work?” and “How do the anesthetic drugs make me fall asleep?”

12918623_897601023682141_1514164364_n

The short answer to both questions is, “We’re not sure.”

This column is designed as a brief tutorial for non-anesthesiologists who wish to better comprehend how anesthetic drugs work.

General anesthesia is the sum of hypnosis (sleep), amnesia, analgesia (pain relief), and the lack of any motion response to pain. Propofol and barbiturates cause hypnosis. Versed and other benzodiazepines cause amnesia. Narcotics such as morphine and fentanyl cause analgesia. Paralyzing drugs such as rocuronium, vecuronium and succinylcholine cause muscle relaxation and lack of motion.

The potent inhaled anesthetics sevoflurane, desflurane, and isoflurane produce all four of the effects of hypnosis, amnesia, analgesia, and lack of motion.

The molecules of anesthetic drugs have great diversity. Some are very small, such as nitrous oxide, while others such as propofol or barbiturates have complex formulas. Some are gases and some are injected liquids. This diversity leads investigators to postulate that there are multiple mechanisms of action for anesthetic drugs on the brain.

Drugs such as propofol and Versed are injected into the bloodstream and are circulated to the central nervous system, where they carry out their effect on brain cells. Inhaled anesthetics such as sevoflurane and desflurane traverse from the lungs into the bloodstream and are circulated to the central nervous system, where they carry out their effect on brain cells.

Once in the brain, it’s not clear how anesthetic drugs work. Most anesthetic drugs are hydrophobic, which literally translates to “water fearing.” This means their molecules are more soluble in fat than in water. Anesthetic drugs exhibit a correlation between their potency and how hydrophobic they are. The entry of any drug into a brain cell must be via the outer lining, or membrane, of that cell. Investigators believe anesthetics must move through, or bind to, the fat-soluble aspects of the membranes of brain cells. The drugs likely then bind to proteins within the cell membranes, and cause their anesthetic effect by changing the characteristics of ion channels within the cell membranes. There is no unifying theory as to how this occurs, but it is known that anesthetic agents have effects on brain cell membrane proteins, which depend on the hydrophobic, electrostatic, and size properties of the individual drug.

Specific examples in our understanding of anesthetic actions include:

(1) Barbiturate drugs, propofol, and inhalational anesthetics are known to act by potentiating a brain chemical called gamma-aminobutyric acid, or GABA. GABA is an inhibitory neurotransmitter, meaning it’s a brain chemical which inhibits other brain activity. This inhibition in some way promotes unconsciousness.

(2) The anesthetics nitrous oxide and ketamine are known to antagonize an excitatory Nmethyl-d-aspartate (NMDA) subtype of neurotransmitter. By blunting this excitatory process, the drugs work to promote unconsciousness.

The takeaway message is that no specific premise exists to explain how all the different general anesthetic drugs work on the brain. A variety of mechanisms likely results in similar effects on the brain, each eliminating the transmission of sensory messages to the brain and initiating unconsciousness.

Anesthesiologists administer other types of drugs, including narcotics, paralyzing drugs, and local anesthetics. The mechanisms of action of these medications are better understood.

fentanyl

Narcotics such as morphine, fentanyl, Demerol, or Dilaudid cause pain relief by binding to opioid receptors in the brain (or the spinal cord). The most common narcotic side effects, e.g. sleepiness and nausea, also arise from the direct effect of the narcotics on the brain. Narcotics bind to three specific receptors in the central nervous system: the mu, delta, and kappa receptors. The mu receptor is primarily responsible for the pain-relieving and euphoria-inducing effects of narcotics. Investigators are searching for new narcotics to specifically target the mu receptor, with the aim of reducing side effects of sedation and nausea.

0409-9558-05_tcm81-3807

Muscle relaxants (muscle paralyzing drugs) such as rocuronium, vecuronium, and succinylcholine act on the body’s peripheral skeletal muscles. Muscles normally contract when a neurotransmitter molecule named acetylcholine travels from a nerve ending and binds to a receptor on the neuromuscular junction on the muscle. This binding causes the muscle to contract. Succinylcholine paralyzes muscles by binding to and activating the acetylcholine receptor, first by causing a muscle contraction and then by rendering the muscle flaccid. Rocuronium and vecuronium paralyze muscles by competitively binding to the receptor and blocking the normal access of acetylcholine, which renders the muscle flaccid.

8178932_orig

Local anesthetic drugs such as lidocaine, bupivicaine (Marcaine), and ropivicaine temporarily block the function of nerves outside the central nervous system. These local anesthetic drugs block the peripheral nerve from conducting of the feeling of pain to the brain. Nerve conduction is dependent on the opening of sodium channels in nerve cell membranes, allowing an influx of sodium ions into the nerve. The blocking of sodium transport renders the nerve incapable of transmitting the pain message.

Modern anesthetic care can involve all the drugs discussed above. For example, in a general anesthetic for an abdominal surgery, the anesthesiologist may inject Versed into the IV as a premedication to reduce anxiety, then inject propofol into the IV to initiate sleep, and inject rocuronium into the IV to induce muscle relaxation/paralysis prior to inserting an endotracheal breathing tube. General anesthesia is then maintained by the administration of a potent inhaled anesthetic gas such as sevoflurane, supplemented by the intravenous injection of a narcotic such as fentanyl to assure post-operative pain relief.

Physician anesthesiologists must master the diverse anesthetic drug repertoire of injectable hypnotics, narcotics, muscle relaxants, as well as the inhaled general anesthetics. The selection of the proper anesthetic drugs and doses for each individual patient makes anesthesiology both fun and fascinating.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

LESSONS LEARNED REGARDING SUGAMMADEX

THE ANESTHESIA CONSULTANT

Regarding sugammadex and residual neuromuscular blockade: I’m aware of two cases of residual neuromuscular blockade which occurred during the past year. Both cases involved obese patients who required emergency reintubation. Both cases were near misses for brain death. Both of these near misses would never have occurred if sugammadex had been used.

The first case was a 50-year-old, 120 kilogram male for an endoscopic retrograde cholangiopancreatography (ERCP). The procedure was to be done in the prone position, and required endotracheal intubation. The intubation was easily performed, and was facilitated with 60 mg of rocuronium for paralysis. The patient was turned prone, and the procedure commenced. After only 15 minutes of operating time, the gastroenterologist announced that the procedure was over. Electrical nerve stimulation of the train of four (TOF) at the facial nerve with a Life Tech Mini Stim showed one twitch. The anesthesiologist injected 5 mg of neostigmine and 1 mg of glycopyrrolate IV, and the patient was turned supine. After ten minutes, the TOF nerve stimulation of the facial nerve showed four equal twitches, and the sevoflurane anesthesia was discontinued. The patient was allowed to return to spontaneous breathing, and he opened his eyes. The trachea was extubated. Within the first two minutes, the patient had inadequate strength for spontaneous respiration. On 100% oxygen via mask, his oxygen saturation dropped from 100% to 80%. 120 mg of succinylcholine was injected IV, and an emergency reintubation was performed. The repeat intubation was more difficult than the original intubation, and required two looks before the trachea was visualized. The nadir oxygen saturation was 60%. The patient was kept asleep for thirty additional minutes, until nerve stimulation at the ulnar nerve showed both TOF and sustained tetany without fade. At that point the trachea was extubated. The patient had no brain damage, and he was discharged home ninety minutes later.

The second case was a 45-year-old, 120 kilogram male with obstructive sleep apnea for a uvulopalatopharyngoplasty (UPPP) and tonsillectomy. The endotracheal intubation was easily done, and was facilitated with 70 mg of rocuronium for paralysis. The surgery lasted 60 minutes. The anesthesiologist injected 5 mg of neostigmine and 1 mg of glycopyrrolate IV fifteen minutes prior to the end of surgery. At the conclusion of surgery, electrical nerve stimulation of the facial nerve with a Life Tech Mini Stim showed four equal twitches in the TOF, and the sevoflurane anesthesia was discontinued. The patient was allowed to return to spontaneous breathing, and opened his eyes. The trachea was extubated. Within the first minute, the patient was awake and breathing, but had jerky breathing pattern and was unable to ventilate himself effectively. On 100% oxygen via mask, his oxygen saturation dropped from 100% to 70%. 200 mg of propofol and 120 mg of succinylcholine were injected IV, and an emergency reintubation was performed. The repeat intubation was more difficult than the original intubation because of blood in the mouth and the oral surgery, and required two looks before the trachea was visualized. The nadir oxygen saturation was 49%. The patient was kept asleep for thirty additional minutes until nerve stimulation at the ulnar nerve showed both TOF and sustained tetany without fade. At that point the trachea was extubated. The patient had no brain damage. He was a planned admission to the hospital, and the remainder of his hospital course was uncomplicated.

Several teaching points are warranted:

  1. If succinylcholine been used for the intubations, the large intubating doses of rocuronium would have been avoided, and the inadequate reversal of the rocuronium intubating doses would likely not have occurred.
  2. If smaller doses of rocuronium been used for intubation, the inadequate reversal of the rocuronium intubating doses would likely not have occurred.
  3. These two cases were done prior to sugammadex availability. In the era of sugammadex, beginning now in 2016, these two near misses should never occur. Sugammadex is a modified γ-cyclodextrin which shows a high affinity for rocuronium and vecuronium. Sugammadex forms a tight inclusion complex with either rocuronium or vecuronium, resulting in rapid reversal of neuromuscular blockade. Sugammadex is able to reverse a moderate profound neuromuscular blockade with a dose of 2.0 mg/kg, and a profound neuromuscular blockade with a dose of 4.0 mg/kg.(1) In my experience, these doses of sugammadex completely reverse rocuronium paralysis within 30-40 seconds. Inadequate neuromuscular blockade reversal should never occur in the era of sugammadex. The past practice of administering neostigmine plus glycopyrrolate to reverse neuromuscular blockade, and then waiting up to ten minutes, is an inferior pharmacologic measure when compared to sugammadex. Reversal with neostigmine plus glycopyrrolate is slow, unreliable, and at times incomplete. While it’s true that a 200 mg ampoule of sugammadex costs approximately $100, that sum of money is trivial when compared to the cost of the lawsuit that would have occurred if either of the two case studies above had resulted in brain death due to delayed or unsuccessful reintubation. In my medical-legal consulting practice I see multiple cases of failed or delayed endotracheal intubations that result in brain death and multimillion-dollar closed malpractice claims.
  4. Residual neuromuscular blockade cannot always be reliably excluded by using qualitative monitoring such as a Life Tech MiniStim device to monitor TOF. The TOF is monitored by comparing the amplitude of the fourth (T4) to the first (T1) evoked mechanical response at the facial nerve or the ulnar nerve. The T4/T1 ratio, or the TOF ratio, coincides with symptoms of peripheral muscle weakness.At a TOF ratio less than 0.60, signs of muscle weakness and ptosis are easily observed. When TOF ratios recover to 0.70, the majority of patients are able to sustain head lift and eye opening. A very low TOF ratio between 0.1 and 0.5 is easily detected by a qualitative nerve stimulator. However, TOF ratios between 0.5 and 1.0 can be difficult to discern visually. Many clinicians are unable to detect fade when TOF ratios exceed 0.30 to 0.4.(1) Qualitative neuromuscular monitoring of the facial nerve twitch can be deceiving. Applying the peripheral nerve stimulator to the ulnar nerve at the adductor pollicis is the gold standard, and this site must be used for the pre-reversal assessment even when the ulnar nerve and thumb are not accessible intraoperatively. Recovery from neuromuscular paralysis should be present when a TOF count without fade has been confirmed at the adductor pollicis.(2) In a partially paralyzed patient, a visually undetectable fade of the TOF at the facial nerve may coincide with a visually detectable fade in TOF when the ulnar nerve is tested. When a patient’s arms are tucked during surgery, or when the ulnar nerve area is distant from the anesthesiologist’s location, it may be impossible to test ulnar nerve stimulation intraoperatively. Prior to extubation, when the ulnar nerve is accessible, ulnar nerve stimulation will convey a more accurate assay of the level of neuromuscular reversal.
  5. Immediate reversal of neuromuscular blockade induced by rocuronium is possible with a larger dose of sugammadex of 16 mg/kg. To facilitate intubation, a dose of succinylcholine (1 mg/kg) will cause a neuromuscular blockade of 4 – 5 minutes in duration. If an airway is found to be difficult or if the intubation is found to be impossible, the anesthesiologist has no way to return the patient to spontaneous breathing until these 4 – 5 minutes elapse. To facilitate intubation, a dose of rocuronium (0.5 – 1 mg/kg), if immediately reversed by sugammadex 16 mg/kg, will cause a shorter duration of paralysis than if succinylcholine were used. It remains to be seen whether this fact will lead to increased use of rocuronium rather than succinylcholine in difficult endotracheal intubations in which a potential early return to spontaneous ventilation is deemed prudent.

 

Healthcare systems are likely to promote selective or infrequent utilization of the new neuromuscular paralysis antidote sugammadex because of its cost. For your practice, and for mine, use the drug when you need it. You’re not personally paying the $100 price for the dose of sugammadex. If you have a serious patient complication because of inadequate neuromuscular reversal by the old drug neostigmine, the adverse patient outcome and the resulting lawsuit may cost you a whole lot more than that $100.

For the record, I have no financial interest or investment in sugammadex. I just know a good product when I see one.

AN ANESTHESIOLOGIST’S SALARY

THE ANESTHESIA CONSULTANT

How much money does an anesthesiologist earn? What is a physician anesthesiologist’s salary in today’s marketplace?

screenshot2011-07-26at3-30-41pm

Let me begin by offering two anecdotes:

  • I was an invited visiting anesthesia professor at a major university this year, and following one of my lectures an anesthesiology resident approached me for a discussion. During our conversation he revealed that his student loan debt was $300,000. In 2014 the published average student loan debt for a physician was $183,000. I believe a higher estimate is not unusual, particularly if the student doctor attended private medical school and/or college.
  • I recently received an email from a medical student who was considering anesthesia as a career specialty, but his concern was: is the bottom about to fall out for anesthesiologists’ salaries? Should he perhaps avoid a career in anesthesiology?

Each anecdote concerns the issue of how much anesthesiologists earn, and what will that number be in the future?

The good news for the future of anesthesia careers is that the number of surgeries in the United States is expected at increase as the Baby Boomers age. The demand for anesthesia services will grow. Who will provide these services, and what will they be paid?

How much money do anesthesiologists currently make?

It depends.

If you do a Google search on this question, most of the published answers vary from $275,000 to $360,000 per year.

This sounds like a lot of money, but recall that to reach that salary, an anesthesiologist must finish 4 years of medical school and a 4-year anesthesia residency. At a minimum these young anesthesiologists are 30 years old. The deferred gratification is significant. Had they gone to work after college at age 22 and been promoted in a business job for 8 years, that individual might own a home, be saving for their children’s college educations, and would not have the debt from 4 years of medical school.

Let’s assume an individual does persevere and finish their anesthesia residency at age 30, and is now seeking an anesthesia job with that aforementioned average salary of $275,000 to $360,000 per year.

The first question: is that advertised salary a number prior to deductions for the big three of pension plan, health insurance, and malpractice insurance? If an anesthesiologist earns $300,000 per year, but must subtract these three expenses (let’s estimate pension plan at $45,000, health insurance at $24,000, and malpractice insurance at $20,000) then the income drops to $300,000 minus $89,000 = $211,000 per year, or $17,583 per month before taxes. Subtract again for student loan payments, and the income level continues to decrease. So a critical first question to ask is if the big three benefits are/are not part of the promised salary.

What specific factors determine how high the anesthesiologist’s salary will be? An operating room anesthesia practice is somewhat akin to being a taxi cab driver. You earn income for each ride/anesthetic, and your income depends on how many rides/anesthetics and how long they last. More complex anesthetics such as cardiac cases pay more, but the largest determiner is the duration of time one spends giving the anesthesia care. If you work in a physician anesthesiology practice where an MD stays with each surgical patient 100% of the time, then the only way to increase income is to do more cases or more hours. If you work in a practice which utilizes an anesthesia care team, where one physician anesthesiologist may supervise, for example, 4 Certified Registered Nurse Anesthetists (CRNAs), then a physician’s income is increased because he or she is billing for and supervising care for multiple concurrent surgeries.

Different payers pay different sums per unit time. The top payers are insured patients of less than Medicare age (<65 years old). Among the lowest payers are uninsured patients (who often pay zero), Medicaid and Medicare patients, and Worker’s Compensation patients. Medicare patients routinely pay only 13-20 cents on the billed dollar, and Medicaid pays even lower, so a practice heavy with Medicare and Medicaid patients will compensate their anesthesiologists poorly. Insurance companies (i.e. Blue Cross, Blue Shield, Aetna, United Healthcare) pay whatever rate they have contracted with that anesthesia group. If a particular insurance company pays a low rate, an anesthesia group may refuse to sign a contract with that insurance company. This leaves the anesthesiologist out-of-network with that company, which can mean a higher payment or co-payment for the patient as a result of the insurance company’s refusal to negotiate a fair reimbursement.

Just as taxi cab drivers are being supplanted by Uber and Lyft, cheaper models of anesthesia care are popping up, and the penetration of these models into the future marketplace is unknown. One model is having a CRNA do the anesthetic independently without any physician anesthesiologist present. This is currently legal in 27 states (see map). At the current time, in my home state of California, independent CRNA practice is legal, but the penetration of this model in the marketplace is very minimal. The Veterans Affairs hospitals are currently pondering a move to allow CRNAs to practice independently without any physician anesthesiologist present. You can expect to see a higher penetration of the anesthesia care team, where one physician anesthesiologist may supervise, for example, 4 CRNAs, and a decrease in practices where an MD anesthesiologist stays with each patient 100% of the time.

To be blunt, my impression is that the future marketplace is unlikely to pay for a physician anesthesiologist to do solo anesthesia care for each and every surgical patient.

In the current marketplace a young graduate anesthesiologist may enter one of several different models of anesthesia practices. Each has a different level of salary expectation. The various models are listed below, in roughly a higher-income-per-anesthesiologist to lower-income-per-anesthesiologist order:

  1. A single-specialty anesthesia group that shares income fairly. This group may be as small as 5 or as large as hundreds of physician anesthesiologists, with or without additional CRNAs. Such a group usually has an exclusive contract with a hospital or hospitals to provide all anesthesia services, which can include trauma, obstetrics, and 24-hour emergency room coverage. A very large single-specialty anesthesia group may contract with many hospitals in a geographic area. In a single-specialty model, that single-specialty group receives all the anesthesia billings, and the income is divided, usually in some form of “eat-what-you-provided” formula. Those MDs who worked the most receive a proportional increase in their income. A new MD may have a one-year try-out before they become a partner, after which they are entitled to an equal income per unit time. This model where anesthesiologists are partners, is typically more lucrative than models where the anesthesiologists are employed by another entity. A survey by Medscape on anesthesiologists’ salaries in 2016 showed that male self-employed anesthesiologists (model #1) earned an average income of $413,000, while male anesthesiologist employees (see models #2 – #8 below) earned an average income of $336,000.
  2. A single-specialty anesthesia group in which a chairman (or a small oligopoly of MDs) collect the money, and then employ and grant a salary to everyone below them in the company. New hires are paid less, often with no potential to increase their income. This type of system preys on junior anesthesiologists.
  3. A multispecialty medical group. A multispecialty medical group has a bevy of primary care physicians who refer internally to their specialist surgeons, who then utilize their internal group of anesthesiologists. This is a secure job for anesthesiologists because the stream of cases is guaranteed by the physicians within their multispecialty group. A disadvantage is that incomes from lower paying specialties (primary care MDs) and higher paying specialties (i.e. cardiologists, surgeons, and anesthesiologists) are pooled. The lower paying specialists usually have their salaries raised, and the anesthesiologists will be subsidizing them.
  4. An HMO. In California the Health Maintenance Organization (HMO) Kaiser Permanente has a large share of the marketplace. The entity known as the Permanente Medical Group is the multispecialty integrated medical group which works at the Kaiser hospitals and clinics. The reimbursement model will be similar to that described in #3 above.
  5. University anesthesia groups. A university employs MDs as a multispecialty medical group, and the model is similar to #3 above. A difference is that university groups have various taxes and fees on their income that go to the betterment and growth of the medical school and the university hospital system. In addition, some university hospitals provide care to indigent populations that may have higher percentage of poor payers such as Medicaid or uninsured patients.
  6. National anesthesia companies. In this model, a national company obtains the anesthesia contract for a hospital or multiple facilities, and then that national company hires and employs anesthesiologists. The company bills for the anesthesia services provided, pays their employee anesthesiologists whatever sum they’ve agreed to pay them, and the difference between the received monies and the owed salaries is profit that goes to stockholders of the national company. This model is problematic for our specialty, because a percentage of the anesthesia fees goes to stockholders who had zero to do with performing the professional service.
  7. Veteran’s Affairs (VA) hospital anesthesia groups. At the present time, VA hospitals are staffed by anesthesiologists who are employees of the VA system. As mentioned above, there are politicians pushing for the VA to allow CRNAs to practice independently, unsupervised by physician anesthesiologists. The American Society of Anesthesiologists is opposed to this change, believing that our veterans deserve physician anesthesiologists.
  8. Locum tenens assignments. These are part-time, week-long, or month-long anesthesia duties, paid for at a daily rate. A typical fee for a full day’s work may be a pre-tax payment of $1200/day (not including the big three of pension, health or malpractice insurance).

As stated above, the good news for the future of anesthesia careers is that the number of surgeries in the United States is expected at increase as the Baby Boomers age. The demand for anesthesia services will grow. The unknown fiscal factors for the future of our specialty are:

  1. What will insurers/Medicare/Medicaid/the Affordable Care Act pay for these anesthesia services? Will a single payer government health plan ever arrive, and if it does what will anesthesiologists be paid?
  2. Who will be giving these services? Physician anesthesiologists, anesthesia care teams involving physician anesthesiologists plus CRNAs, anesthesia care teams involving physician anesthesiologists plus Anesthesia Assistants, or independent CRNAs?
  3. The American Society of Anesthesiologists is attempting to rebrand the practice of anesthesiology with the concept of the Perioperative Surgical Home (PSH), in which physician anesthesiologists are responsible for all aspects of preoperative, intraoperative, and postoperative medical care for patients around the time of surgery. This expanded role includes preoperative clinics and postoperative pain control and medical management. To what degree can/will the PSH change the job market for graduating anesthesiologists?

In any case, as I wrote on the Home Page of theanesthesiaconsultant.com website, “the profession of medicine offers a lifetime of fascination, and no specialty is more fascinating than anesthesiology.” If a college student or a medical student is truly interested in a career in anesthesia, I remain encouraging to them, regardless of these uncertainties regarding the future.

Check out . . . THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

DENTAL ANESTHESIA DEATHS . . . GENERAL ANESTHESIA FOR PEDIATRIC PATIENTS IN DENTAL OFFICES

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

GENERAL ANESTHESIA FOR DENTAL OFFICES CASE PRESENTATION: A 5-year-old developmentally delayed autistic boy has multiple dental cavities. The dentist consults you, a physician anesthesiologist, to do sedation or anesthesia for dental restoration. What do you do?

gauge-needles-used-intramuscular-injection_d9f6cc4b150fa44

DISCUSSION:  Children periodically die in dental offices due to complications of general anesthesia or intravenous sedation. Links to recent reports include the following:

3-year-old girl dies in San Ramon, CA after a dental procedure in July 2016.

A 14-month-old child, scheduled to have 2 cavities filled, dies in an Austin, TX dental office. The dentist and an anesthesiologist were both present.

A 6-year-old boy, scheduled to have teeth capped at a dental clinic, has anesthesia and dies after the breathing tube is removed.

Another 6-year-old boy, scheduled to have a tooth extracted by an oral surgeon, dies after the oral surgeon administers general anesthesia.

Pediatric dentists use a variety of tactics to keep a typical child calm during dental care. The child is encouraged to view a movie or cartoon while the dental hygienist or dentist works. The parent or parents are encouraged to sit alongside their child to provide emotional support. If a typical child requires a filling for a cavity, the dentist can utilize nitrous oxide via a nasal mask with or without local anesthesia inside the mouth.

These simple methods are not effective if the child has a developmental delay, autism, behavioral problems, or if the child is very young. Such cases sometimes present to a pediatric hospital for anesthetic care, but at times the child will be treated in a dental office. Possible anesthesia professionals include a physician anesthesiologist, a dental anesthesiologist, or an oral surgeon (who is trained in both surgery and anesthesia).

 

HOW WOULD A PHYSICIAN ANESTHESIOLOGIST ANESTHETIZE A CHILD IN A DENTAL OFFICE?

There are a variety of techniques an anesthesiologist might use to sedate or anesthetize a young child. The correct choice is usually the simplest technique that works. Alternative methods include intramuscular sedation, intravenous sedation, or potent inhaled anesthetics.

 

ANESTHESIA INDUCTION:

The first decision is how to begin the anesthetic on an uncooperative child. Options for anesthesia induction include:

  1. Intramuscular sedation. A typical recipe is the combination of 2 mg/kg of ketamine, 0.2 mg/kg of midazolam, and .02 mg/kg of atropine. These three medications are drawn up in a single syringe and injected into either the deltoid muscle at the shoulder or into the muscle of the anterior thigh. Ketamine is a general anesthetic drug that induces unconsciousness and relieves pain. Midazolam is a benzodiazepine which induces sleepiness and decreases anxiety. Ketamine can cause intense dreams which may be frightening. Midazolam is given because it minimizes ketamine dreams. Atropine offsets the increased oral secretions induced by ketamine. Within minutes after the injection of these three drugs, the child will become sleepy and unresponsive, and the anesthesiologist can take the child from the parent’s arms and bring the patient into the operating room. Most anesthesiologists will insert an intravenous catheter into the patient’s arm at this point, so any further doses of ketamine, midazolam, or propofol can be administered through the IV.
  2. Oral sedation with a dose of 0.5-0.75 mg/kg of oral midazolam syrup (maximum dose 20 mg). If the child will tolerate drinking the oral medication, the child will become sleepy within 15- 20 minutes. At this point, the anesthesiologist can take the patient away from the parent and proceed into the operating room, where either an intravenous anesthetic or an inhaled sevoflurane anesthetic can be initiated.

 

MONITORING THE PATIENT:

  1. The patient should have all the same monitors an anesthesiologist would use in a hospital or a surgery center. This includes a pulse oximeter, an ECG, a blood pressure cuff, a monitor of the exhaled end-tidal carbon dioxide, and the ability to monitor temperature.
  2. The anesthesiologist is the main monitor. He or she will be vigilant to all vital signs, and to the Airway-Breathing-Circulation of the patient.

 

MAINTENANCE OF ANESTHESIA:

  1. Regardless of which anesthetic regimen is used, oxygen will be administered. Room air includes only 21% oxygen. The anesthesiologist will administer 30-50% oxygen or more as needed to keep the patient’s oxygen saturation >90%.
  2. Intravenous sedation: This may include any combination of IV midazolam, ketamine, propofol, or a narcotic such as fentanyl.
  3. Local blocks by the dentist. The dentist may inject local anesthesia at the base of the involved tooth, near the superior alveolar nerve to block all sensation to the upper teeth, or near the inferior alveolar nerve to anesthetize all sensation to the lower jaw.
  4. Inhaled nitrous oxide. The simplest inhaled agent is nitrous oxide, which is inexpensive and rapid acting. Used alone, nitrous oxide is not potent enough to make a patient fall asleep. Nitrous oxide can be used as an adjunct to any of the other anesthetic drugs listed in this column.
  5. Potent inhalation anesthesia (sevoflurane). Most dental offices will not have a machine to administer sevoflurane. (Every hospital operating room has an anesthesia machine which delivers sevoflurane vapor.) Portable anesthesia machines fitted with a sevoflurane vaporizer are available. A colleague of mine who worked full time as a roving physician anesthesiologist to multiple pediatric dental offices leased such a machine and used it for years. The advantages of sevoflurane are: i) few intravenous drugs will be necessary if the anesthesiologist uses sevo, and ii) the onset and offset of sevo is very fast—as fast as nitrous oxide. The administration of sevoflurane usually requires the use of a breathing tube, inserted into the patient’s windpipe.
  6. The anesthesiologist will be present during the entire anesthetic, and will not leave.

 

AWAKENING FROM ANESTHESIA:

  1. With intramuscular and/or intravenous drugs, the wake-up is dependent on the time it takes for the administered drugs to wear off or redistribute out of the blood stream. This may take 30-60 minutes or more following the conclusion of the anesthetic.
  2. With inhaled agents such as sevoflurane and nitrous oxide, the wake-up is dependent on the patient exhaling the anesthetic gas. The majority of the inhaled anesthetic effect is gone within 20-30 minutes after the anesthetic is discontinued.
  3. The patient must be observed and monitored until he or she is alert enough to be discharged from the medical facility. This can be challenging if a series of patients are to be anesthetized in a dentist’s office. The medical staff must monitor the post-operative patient and also attend to the next patient’s anesthetic care. It’s imperative that the earlier patient is awake before the anesthesiologist turns his full attention to the next patient.

 

THE ANESTHETIC FOR OUR CASE PRESENTATION ABOVE:

  1. The anesthesiologist meets the parents and the patient, and explains the anesthetic options and procedures to the parent. The parent then consents.
  2. The anesthesiologist prepares the dental operating room with all the necessary equipment in the mnemonic M-A-I-D-S, which stands for Monitors and Machine, Airway equipment, Intravenous line, Drugs, and Suction.
  3. The anesthesiologist injects the syringe of ketamine, midazolam, and atropine into the child’s deltoid muscle. The child becomes sleepy and limp within one minute, and the anesthesiologist carries the child into the operating room.
  4. All the vital sign monitors are placed, and oxygen is administered via a nasal cannula.
  5. An IV is started in the patient’s arm.
  6. The dentist begins the surgery. He or she may inject local anesthesia as needed to block pain.
  7. Additional IV sedation is administered with propofol, ketamine, midazolam, or fentanyl as deemed necessary.
  8. When the surgery is nearing conclusion, the anesthesiologist will stop the administration of any further anesthesia. When the surgery ends, the anesthesiologist remains with the patient until the patient is awake. The patient may be taken to a separate recovery room, but that second room must have an oxygen saturation monitor and a health care professional to monitor the patient until discharge.

CHALLENGES OF DENTAL OFFICE ANESTHESIA:

  1. You’re do all the anesthesia work alone. If you have an airway problem or an acute emergency, you’ll have no other anesthesia professional to assist you. Your only helpers are the dentist and the dental assistant.
  2. The cases are difficult, otherwise you wouldn’t be there at all. Every one of the patients will have some challenging medical issue(s).
  3. You have no preop clinic, so you don’t know what you’re getting into until you meet the patient. I’d recommend you telephone the parents the evening before, so you can glean the past medical and surgical histories, and so you can explain the anesthetic procedure. Nonetheless, you can’t evaluate an airway over the phone, and on the day of surgery you may encounter more challenge than you are willing to undertake.
  4. It’s OK to cancel a case and recommend it be done in a hospital setting if you aren’t comfortable proceeding.
  5. The anesthesiologist usually has to bring his or her own drugs. The narcotics and controlled substances need to be purchased and accounted for by the anesthesiologist with strict narcotic logs to prove no narcotics are being diverted for personal use. All emergency resuscitation drugs need to be on site in the dental office or brought in by the anesthesiologist.
  6. If a sevoflurane vaporizer is utilized, dantrolene treatment for Malignant Hyperthermia must be immediately available.

 

BENEFITS OF DENTAL OFFICE SEDATION AND GENERAL ANESTHESIA:

  1. The parents of the patients are grateful. The parents know how difficult dental care on their awake child has been, and they’re thankful to have the procedures facilitated in a dental office.
  2. The dentist and their staff are grateful. They don’t have a method to safely sedate such patients, and are thankful that you do.
  3. Most cases are not paid for by health insurance, rather they are cash pay in advance.

 

HOW SAFE IS ANESTHESIA AND SEDATION IN A DENTAL OFFICE?

No database can answer the question at present. In 2013 the journal Paediatric Anesthesia published a paper entitled Trends in death associated with pediatric dental sedation and general anesthesia. (1) The paper reported on children who had died in the United States following receiving anesthesia for a dental procedure between1980-2011. Most deaths occurred among 2-5 year-olds, in an office setting, and with a general or pediatric dentist (not a physician anesthesiologist or dental anesthesiologist) as the anesthesia provider. In this latter group, 17 of 25 deaths were linked with a sedation anesthetic.

Another study analyzed closed claims databases of 17 malpractice claims of adverse anesthesia events in pediatric patients in dental offices from 1992 – 2007. (2) Thirteen cases involved sedation, 3 involved local anesthesia alone, and 1 involved general anesthesia. 53% of the claims involved patient death or permanent brain damage. In these claims the average patient age was 3.6 years. Six cases involved general dentists as the anesthesia provider, and 2 involved local anesthesia alone. The adverse event occurred in the dental office in 71% of the claims. Of the 13 claims involving sedation, only 1 claim involved the use of vital sign monitoring. The study concluded that very young patients (≤ 3-years-old) were at greatest risk during administration of sedative and/or local anesthetic agents. The study concluded that some practitioners were inadequately monitoring patients during sedation procedures. Adverse events had a high chance of occurring at the dental office where care is being provided.

If general anesthesia or deep sedation are performed in a dental office, the anesthetist must practice with the same vigilance and standards of care as they would in a hospital or surgery center. Either a physician anesthesiologist, an oral surgeon (acting as both the dental surgeon and the anesthetist), or a dental anesthesiologist may perform the anesthesia. There are no data at this time to affirm that a physician anesthesiologist is the safest practitioner in this setting.

Note: This column addressed the office practice of pediatric dental anesthesia as seen from a physician anesthesiologist’s point of view.

13 MAJOR CHANGES IN ANESTHESIOLOGY IN THE LAST TEN YEARS

THE ANESTHESIA CONSULTANT

Let’s look at 13 major changes in the last ten years of anesthesiology, and give a letter grade to mark the significance of each advance:

final_ten_year_graphic_gif

 

SUGAMMADEX – The long awaited reversal agent for neuromuscular paralysis reached the market in 2016, and by my review, the drug is wonderful. I’ve found sugammadex to reverse rocuronium paralysis in less than a minute in every patient who has at least one twitch from a nerve stimulator. The dose is expensive at about $100 per patient, but at this time that’s cheaper than the acquisition costs for neostigmine + glycopyrrolate. The acquisition cost of neostigmine + glycopyrrolate at our facilities exceeds $100, and this combination of drugs can take up to 9 minutes to reverse rocuronium paralysis. Sugammadex reversal can make the duration of a rocuronium motor block almost as short acting as a succinylcholine motor block, and sugammadex can also eliminate complications in the Post Anesthesia Care Unit due to residual postoperative muscle paralysis. Grade = A.

 

SHORTAGES OF GENERIC INTRAVENOUS DRUGS – Over the last five years we’ve seen unexpected shortages of fentanyl, morphine, propofol, ephedrine, neostigmine, glycopyrrolate, meperidine, and atropine, to name a few. These are generic drugs that formerly cost pennies per ampoule. In the current marketplace, generic manufacturers have limited the supplies and elevated the prices of these medications to exorbitant levels. I wish I’d had the foresight and the money ten years ago to invest in a factory that produced generic anesthetic drugs. Grade = F.

 

THE PERIOPERATIVE SURGICAL HOME – The American Society of Anesthesiologists has been pushing this excellent concept for years now—the idea being that a team of physician anesthesiologists will manage all perioperative medical care from preoperative clinic assessment through discharge, including intraoperative care, postoperative care and pain management in the PACU, the ICU, and the hospital wards. The goal is improved patient care with decreased costs. It’s not clear the idea has widespread traction as of yet, and the concept will always be at odds with the individual aspirations of internal medicine doctors, hospitalists, intensivists, surgeons, and certified nurse anesthetists, all who want to make their own management decisions, and all who desire to be paid for owning those decisions. Grade = B-.

 

MULTIMODAL PAIN MANAGEMENT FOLLOWING TOTAL JOINT REPLACEMENTS – The development of pain management protocols which include neuroaxial blocks, regional anesthetic blocks, local anesthetic infiltration by surgeons, oral and intravenous pain medications, have advanced the science of pain relief for total knee and total hip replacements. The cooperation between surgeons, anesthesiologists, and internal medicine specialists to develop the protocols has been outstanding, the standardized checklist care has been well accepted, and patients are benefiting. Grade = A.

 

ULTRASOUND GUIDED REGIONAL ANESTHESIA – Regional anesthetic blocks are not new, but visualizing the nerves via ultrasound is. The practice is becoming widespread, and the analysis of economic and quality data is ongoing. Ultrasound guided regional anesthesia is a major advance for painful orthopedic surgeries, but I worry about overuse of the technique on smaller cases for the economic benefit of the physician wielding the ultrasound probe. A second concern is the additive risk of administrating two anesthetics (regional plus general) to one patient. I’ve reviewed medical records of patients with adverse outcomes related to regional blocks, and I’m concerned ultrasound guided regional anesthesia may be creating a new paradigm of postoperative complications, e.g. prolonged nerve damage or intravascular injection of local anesthetics. In the future I look forward to seeing years of closed claims data regarding this increasing use of regional anesthesia. Grade = B.

 

VIDEOLARYNGOSCOPY – The invention of the GlideScope and its competitors the C-MAC, King Vision, McGrath and Airtraq videolaryngoscopes was a major advance in our ability to intubate patients with difficult airways. My need for fiberoptic intubation has plummeted since videolaryngoscopy became available. I’d recommend that everyone who attempts traditional laryngoscopy for endotracheal intubation have access to a video scope as a backup, should traditional intubation prove difficult. Grade = A.

 

ANESTHESIOLOGIST ASSISTANTS (AAs) – The American Society of Anesthesiologists is championing the idea of training AAs to work with physician anesthesiologists in an anesthesia care team model. A primary reason is to combat the influence and rise in numbers of Certified Registered Nurse Anesthetists (CRNAs) by inserting AAs as a substitute. Not a bad idea, but like the Perioperative Surgical Home, the concept of AAs is gaining traction slowly, and the penetration of AAs into the marketplace is minimal. To date there are only ten accredited AA education programs in the United States. Grade = B-.

 

CHECKLISTS – We now have pre-incision Time Outs, pre-induction Anesthesia Time Outs, and pre-regional anesthesia Block Time Outs. It’s hard to argue with these checklists. Even if 99.9% of the Time Outs change nothing, if 0.1% of the Time Outs identify a miscommunication or a laterality mistake, they are worth it. Grade = A.

 

ANESTHESIA ELECTRONIC MEDICAL RECORDS (EMRs)– The idea is sound. Everything in the modern world is digitalized, so why not medical records? The problem is the current product. There are multiple EMR systems, and the systems cannot communicate with each other. Can you imagine a telephone system where Sprint phones cannot communicate with AT&T phones? The current market leader for hospitals is Epic, a ponderous, expensive system that does little to make the pertinent information easier to find in medical charts. For acute care medicine such as anesthetic emergencies, the medical charting and documentation in Epic gets in the way of hands-on anesthesia care. In the past, when I administered 50 mg of rocuronium, I simply wrote “50” in the appropriate space on a piece of paper. In Epic I have to make at least 4 mouse clicks to do the same thing. This Epic entry cannot be made on a touch screen because the first rocuronium window on the touch screen is a three-millimeter-tall box, too small for a finger touch. I’d like to see Apple or Google develop better EMR software than we have at present. Perhaps the eventual winning product will be voice activated or will involve easy touch screen data entry and data access. And all EMR systems should interact with each other, so patient privacy medical information can be portable. Grade = C-.

 

THE ECONOMICS OF ANESTHESIA – When I began in private practice in 1986, most successful anesthesiologists joined a single-specialty anesthesia group. This group would cover a hospital or several hospitals along with nearby surgery centers and offices. The group would bill for physician services, and insurance companies would reimburse them. Each physician joining the group would endure a one or two-year tryout period, after which he or she became a partner. Incomes were proportional to the number of cases an individual attended to. The models are changing. Smaller anesthesia groups are merging into larger groups, better equipped to negotiate with healthcare insurers and ObamaCare. More and more healthcare systems are employing their own anesthesiologists. In a healthcare system, profits are pooled and shared amongst the varying specialists. This model is not objectionable. Anesthesiologists share the profits with less lucrative specialties such as internal medicine and pediatrics, but the anesthesiologists are assured a steady flow of patients from the primary care physicians and surgeons within the system. The end result is less income than in a single-specialty anesthesia group, but more security. Grade = B.

 

THE SPECTER OF A BAN ON BALANCE BILLING – In a perfect world all physician groups would be contracted with all health insurance companies, at a monetary rate acceptable to both sides. Unfortunately there are insurance company-physician group rifts in which an acceptable rate is not negotiated. In these instances, the physician provider for a given patient may be out of network with the patient’s insurer, not because of provider greed (as portrayed by some politicians and insurers) but because the insurance company did not offer a reasonable contracted rate. Some politicians believe physician out-of-network balance billing should be outlawed. This would give unilateral power to insurance companies. Why would an insurance company offer a reasonable rate to a physician provider group, if the insurance company can pay the physicians a low rate and the new law says the physicians have no alternative but to accept it as payment in full? The no-balance-billing politicians will portray patients as victims, but if they succeed in changing the laws, physicians will become victims. Physicians as well as consumers must unite to defeat this concept. Grade = F.

 

CORPORATE ANESTHESIA – National companies are buying multiple existing anesthesia groups and changing the template of our profession in America. The current physician owners of a practice can sell their group to a publically traded national company for a large upfront payoff. The future salaries of anesthesiologists of that group are then decreased, and the rest of the profit formerly garnered by the physicians goes instead to the bottom line of the national company’s shareholders. If this model becomes widespread, the profession of anesthesiology will morph into a job populated by moderately reimbursed employees. Grade = D.

 

INDEPENDENT PRACTICE FOR CRNAs – Anesthesiology is the practice of medicine. In a two-year training program, an ICU nurse can learn to administer propofol and sevoflurane, and how to intubate most patients, and become a CRNA. It takes a physician anesthesiologist to manage complex preoperative medical problems, intraoperative complications, and postoperative medical complications. I understand rural states such as Montana and the Dakotas cannot recruit enough physician anesthesiologists to hospitals in their smallest towns, but for states like California to legalize independent anesthesia practice for CRNAs is unconscionable. Grade = D.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

ANESTHESIA ERRORS: MALPRACTICE OR NOT?

THE ANESTHESIA CONSULTANT

If a patient suffers a bad outcome after anesthesia, did the anesthesiologist commit malpractice? If there was an anesthesia error, was it anesthesia malpractice?

medical-malpractice-anesthesia-errors-1-638

Not necessarily. There are risks to every anesthetic and every surgery, and if a patient sustains a complication, it may or may not be secondary to substandard anesthesia care.

Let’s look at the most common reasons for anesthesia malpractice claims. In a study by Ranum,(1) researchers examined a total of 607 closed claims from a single national malpractice insurance company over five years between 2007 and 2012. The most frequent anesthesia-related injuries reported were:

  1.   Teeth damage — 20.8 percent of the anesthesia medical malpractice claims
  2.   Death — 18.3 percent
  3.   Nerve damage — 13.5 percent
  4.   Organ damage — 12.7 percent
  5.   Pain — 10.9 percent
  6.   Cardiopulmonary arrest — 10.7 percent

When the minor claims for teeth damage are omitted, claims for death and cardiopulmonary arrest account for nearly one in four closed claims for anesthesiologists. This shows the severe nature of anesthesia bad outcomes.

How can we discern whether a bad patient outcome is a risk for a malpractice claim?

There are four elements to a medical malpractice claim. They are as follows (2):

  1. Duty to care for the patient. The anesthesiologist must have made a contract to care for the patient. The anesthesiologist meets the patient, takes a history, reviews the chart, does a pertinent physical exam, and discusses the options for anesthetic care. The anesthesiologist then obtains informed consent from the patient to carry out that plan, and the duty to care for the patient is established.
  2. Negligence occurs if the anesthesiologist failed in his or her duty to care, that is, he or she performed below the standard of care. The standard of care is defined as the level of care expected from a reasonably competent anesthesiologist. If a lawsuit is eventually filed, anesthesiology expert witnesses will testify for both the defense and the plaintiff as to what the standard of care was for this case. If the defendant anesthesiologist performed below the standard of care, they are vulnerable to losing the lawsuit.
  3. The plaintiff must prove the negligence was a proximate cause of the injury to the patient. If a lawsuit is eventually filed, expert witnesses will argue how and why the negligence was linked or was not linked to the adverse outcome.
  4. The injury or loss can be measured in monetary compensation to the plaintiff.

Let’s look at two fictional case studies to demonstrate how a bad outcome may or may not be related to anesthesia malpractice:

CASE ONE: A 70-year-old man is scheduled to have laparoscopic abdominal surgery for a partial colectomy to remove a cancer in his large intestine. Prior to his surgery he has a complete history and physical by his internal medicine doctor, and the results of that workup are in the medical chart. The patient medical history is positive for hypertension, hyperlipidemia, and obesity. His Body Mass Index, or BMI, is elevated at 32. His blood pressure is 140/85, and his physical exam is otherwise unremarkable. Prior to the surgery, the anesthesiologist requests clearance from a cardiologist. The cardiologist performs an exercise stress echocardiogram, which is read as normal. The anesthesiologist plans a general anesthetic, and obtains informed consent from the patient. During the informed consent, the anesthesiologist tells the patient that risks involving the heart, the lungs, or the brain are small but not zero. The patient accepts these risks.

The surgery and anesthesia proceed uneventfully. The patient is awakened from general anesthesia and taken to the Post Anesthesia Care Unit. The patient is drowsy and responsive, with a blood pressure of 100/60, a heart rate of 95, a respiratory rate of 16, a temperature of 36.0 Centigrade, and an oxygen saturation of 96% on a face mask delivering 50% oxygen. A Bair Hugger blanket is applied to warm the patient, and morphine sulfate 2 mg IV is given for complaint of abdominal pain.

Thirty minutes later, the patient develops acute shortness of breath, and his oxygen saturation drops to 75%. The anesthesiologist sees him and evaluates him. The cause of the shortness of breath and drop in oxygen level are unclear. The concentration of administered oxygen is increased to 100%, but the patient acutely becomes unresponsive. The anesthesiologist intubates the patient’s trachea, and begins ventilating him through the breathing tube. The patient is still unresponsive and has a cardiac arrest. Despite all Advanced Cardiac Life Support treatments, the patient dies.

An expert witness later reviews the chart, and finds the anesthesia management to be within the standard of care prior to, during, and after the surgery. There was no negligence that caused the cardiac arrest. Why did the patient die? The post-mortem exam, or autopsy, in a case like this could show a pulmonary embolism or a myocardial infarction, either of which can occur despite excellent anesthesia care. The patient was elderly, overweight, and hypertensive. Abdominal surgery and general anesthesia in this patient population are not without risk, even with optimal anesthetic care.

CASE TWO: A 55-year old female is scheduled for a facelift at a freestanding plastic surgery center operating room. Her history and physical examination are normal except that she is 5 feet tall and weighs 200 pounds, for a BMI=39. The anesthesiologist plans a general anesthetic, and obtains informed consent from the patient. After the induction of general anesthesia with propofol and rocuronium, the anesthesiologist is unable to place the endotracheal tube in the patient’s windpipe. He tries repeatedly in vain, and during this time the woman’s oxygen saturation drops to dangerous levels below 70%, and remains low for over five minutes. He eventually places the tube successfully. The surgery is cancelled, and the woman fails to wake up. She is transferred to a local hospital and admitted to the intensive care unit. A neurologic workup confirms that she has anoxic brain damage, or brain death.

This is a case where an overweight but otherwise healthy woman walked into a surgery center for an elective surgery, and emerged brain dead. Per the donor card in the patient’s wallet, the family agreed to donate the patient’s organs. Was this outcome due to malpractice? Yes. The anesthesiologist performed below the standard of care, because he failed to keep the patient oxygenated during the multiple attempts to place the breathing tube. An expert witness for the plaintiff testifies that a reasonably competent anesthesiologist would understand and follow the American Society of Anesthesiologists (ASA) Difficult Airway Algorithm, and use alternate techniques to keep the patient oxygenated should the endotracheal tube placement be technically difficult. (These techniques include bag-mask ventilation, placement of a laryngeal mask airway, or use of a video laryngoscope). The failure to keep the airway open and the failure to keep the patient oxygenated led to the anoxic brain damage. An expert witness for the defense concurs with this opinion, and the anesthesiologist’s malpractice insurance company settles the case by paying the patient’s family.

Complications can occur before, during, or after anesthesia. The overwhelming majority of physician anesthesiologists manage their patients at or above the standard of care. When an adverse outcome occurs there may very well be no negligence or malpractice, and one should expect the legal system to award little or no malpractice award payments.

Does that mean that if the standards of care are adhered to, then there will be no malpractice payment following a bad outcome? Unfortunately, the data say no.

The ASA Closed Claims Project collects closed anesthesia malpractice claim results from the 1970s to the present. From 1975-79, 74% of anesthesia lawsuits resulted in payment. From 1990-99 this proportion declined to 58%. Much of this positive change may be explained by improvements in standards of care, i.e. the change to the routine monitoring of pulse oximetry and end-tidal carbon dioxide levels. In the 1970s, 51% of the lawsuits in which standards of care were met resulted in payment. In the 1990s only 40% of the lawsuits in which standards of care were met resulted in payment, but 40% is not zero.(3)

Other facts about medical malpractice lawsuits: About 93% of malpractice claims close without going to a trial. The average claim that goes to trial involves a 3 to 5 year process.(4) Of the cases that go to trial, 79% of verdicts are for the defendant physician.(5)

Medical errors do occur. Physicians are human. How common are medical errors in anesthesiology? It’s hard to quantitate. Medical errors that do not result in closed malpractice claims are not tabulated.

The issue of medical errors is currently a hot topic. A report published in the The British Medical Journal this week stated that if medical error was a disease, it would rank as the third leading cause of death in the United States, trailing only heart disease and cancer. Medical error was defined as an unintended act of either omission or commission, or one that does not achieve its intended outcome, the failure of a planned action to be completed as intended (an error of execution), the use of a wrong plan to achieve an aim (an error of planning), or a deviation from the process of care that may or may not cause harm to the patient. The authors calculated a mean rate of death from medical error of 251 ,454 cases per year. The authors pointed out that death certificates in the U.S., used to compile national statistics, currently have no facility for acknowledging medical error. The ICD-10 coding system has limited ability to record or capture most types of medical error. The authors recommended that when a medical error resulted in death, both the physiological cause of the death and the related problem with delivery of care should be captured.(6)

Do anesthesiologists commit any of these medical errors? Undoubtedly. What does this mean if you are a patient scheduled for surgery and anesthesia? You should have every expectation your board-certified physician anesthesiologist will practice at or above the standard of care. The chances that you will become an adverse outcome statistic are small, but those chances are not zero.

LARGE-VOLUME LIPOSUCTION: IS IT SAFE?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

THE ANESTHESIA CONSULTANT

I work in a private practice setting in Palo Alto, California, and liposuction is one of the most common plastic surgery procedures performed. The accepted definition of a large-volume liposuction is a total aspirate of greater than 4 liters.

liposuction-fat

Seventy percent of the total aspirate is fat, so if a total volume of 4 liters is harvested, the total volume of fat is 0.7 X 4, or 2.8 liters. Each liter of liposuction fat weighs approximately 2 pounds, so the weight removed in a 4-liter total-aspirate liposuction is 2.8 liters X 2 pounds/liter = 5.6 pounds.

The current accepted upper limit for fat removed in an outpatient liposuction is 5 liters, so the maximum weight of fat removed would be 5 liters X 2 pounds/liter = 10 pounds.

Early in my career, in the late 1980’s, liposuction was a bloody procedure. Prior to surgery healthy outpatients donated their own autologous blood, which they received intraoperatively to treat the expected hemorrhage which accompanied liposuction.

In the late 1980’s, American dermatologist Jeffery Klein introduced the tumescent technique for liposuction, in which dilute solutions of epinephrine and lidocaine were injected into the subcutaneous tissues prior to liposuction. This technique induced vasoconstriction and resulted in decreased blood loss, and made transfusion and post-operative anemia rare.

The volume of tumescent solution injected by the surgeon is roughly equivalent to the total volume expected to be aspirated from the patient. For a large-volume liposuction, 4 – 7 liters of tumescent solution may be injected into the body areas to be suctioned. The tumescent solution includes 1 mg of epinephrine and 20 ml of 1% lidocaine (200 mg lidocaine) per one liter of Lactated Ringers. The complication of local anesthetic toxicity from lidocaine is rare. The maximum dose of lidocaine should be kept < 35 mg/kg, or < 2450 mg for a 70 kg (154 pound) patient. If the surgeon injects six liters, this will total only 1200 mg of lidocaine. Symptoms of epinephrine toxicity are also rare.

Preanesthetic assessment and patient selection are key for safe large-volume liposuction procedures. All patients are ASA I or II, and have stable medical histories. Our facility requires each patient to weigh less than 250 pounds, or to have a BMI < 36. Preoperative labs and ECGs are done only as needed, per standard Ambulatory Surgery Center policies. The procedures are done under general endotracheal anesthesia, and can last from 3 to 8 hours. Our facility, the Plastic Surgery Center in Palo Alto, has two operating rooms. At times the second room is not occupied, and a solo anesthesiologist is the only anesthesia professional present on site and must be prepared to handle any and all emergencies.

A protocol for large-volume liposuction at our facility is as follows:

  1. General anesthesia is induced. An endotracheal tube rather than a supraglottic airway is used. Many procedures involve both supine and prone positioning because anterior and posterior parts of the body are liposuctioned. A Foley catheter is inserted into the bladder.
  2. After prepping and draping, the surgeon injects the tumescent solution into the areas to be liposuctioned. The total volume of the injectate must not exceed 10 liters. In most cases, the total volume of the injectate does not exceed 6 liters.
  3. The liposuction proceeds. The typical aspirate is a mixture of fat and tumescent fluid, with minimal bloody or reddish tinge. The total volume of fat aspirated is not to exceed 5 liters. The ratio of fat/total aspirate in each container is 0.7. If a total of 7 liters of liposuction aspirate is harvested, the total volume of fat is 7 X 0.7, or 4.9 liters.
  4. Fluid intake and output must be balanced. The total intake includes 6 liters of tumescent Lactated Ringers, plus intravenous fluids. Usually the volume of intravenous fluid is kept to less than 1 liter. The output equals the total aspirate volume of 7 liters in this case, plus the urine output. If the urine output is less than 0.5 ml/kg/hour, the diuretic furosemide 10 mg can be administered IV.
  5. Maintaining normothermia is challenging. Large-volume liposuction usually requires exposure of the patient’s body surface from the lower thorax to the knees to room air temperature. Twin Bair Huggers are used to warm both the lower and upper non-operative fields of the patient’s body.
  6. At the conclusion of surgery, constricting garments are applied to the patient’s body to reduce edema and bleeding. General anesthesia is continued until these garments are applied.
  7. Patients are discharged home after a typical PACU time of 75-120 minutes.

 

How safe is large-volume liposuction?

Palo Alto plastic surgeon George Commons and anesthesiologist Bruce Halperin published a retrospective review on 631 consecutive patients from 1986–1998 who underwent liposuction procedures of at least 3 liters total aspirate.(1) Total aspirate volumes ranged from 3 to 17 liters. Complications consisted of minor skin injuries and burns, allergic reactions to garments, and postoperative seromas. Only four patients of 631 (0.6%) developed serious complications, including four patients with mild pulmonary edema and one patient who developed pneumonia postoperatively. These patients were treated appropriately and had uneventful recoveries.

A retrospective study from Germany reported on 2275 large-volume liposuction patients from 1998-2002 in which there were 72 cases of severe complications (3.1%), including 23 deaths.(2) The most frequent complications were bacterial infections (necrotizing fasciitis, gas gangrene, and sepsis), hemorrhage, perforation of abdominal viscera, and pulmonary embolism. Fifty-seven of the 72 complications were clinically evident within the first 24 postoperative hours. Risk factors for the development of severe complications were insufficient standards of hygiene, infiltration of multiple liters of tumescent solution, permissive postoperative discharge, selection of unfit patients, and lack of surgical experience, especially regarding the identification of complications. The striking 1% mortality rate of this series documents that liposuction was dangerous in Germany between 1998 and 2002.

A review of 127,961 cosmetic surgery cases in the U.S. in 2016 showed a 0.9% complication rate in liposuction patients. Overweight patients (BMI = 25-29.9) and obese patients (BMI ≥ 30) were both independent risk factors for post-operative infection and venous thromboembolism.

In a series from Illinois, 69 of 4534 (1.5 percent) of liposuction patients in experienced a postoperative complication.(4) Both the liposuction volume and the patient’s BMI were significant independent risk factors. Liposuction volumes in excess of 100 ml per unit of body mass index were an independent predictor of complications (p < 0.001).

In experienced hands, the major morbidity of large-volume liposuction should be low—no more than the complication rates of 0.6 – 1.5% reported from the United States above. As long as there are patients who desire less fat in their thighs, hips, buttocks, abdomen, knees, arms, or necks, there will be a demand for liposuction. Large-volume liposuction requires an anesthesia professional who’s comfortable managing the perioperative medicine. If you’re considering this surgical procedure, my recommendation is to seek both a surgeon and an anesthesia team who are well trained and experienced.

THE ANESTHESIA CONSULTANT

The printing press was the most influential invention of the last millennium. Now individuals use computers to search for Internet medical knowledge.

THE PRINTING PRESS AND THE REFORMATION . . . , THE INTERNET AND MEDICAL KNOWLEDGE

The book 1000 years, 1000 People by Agnes and Henry Gottlieb identifies Johannes Gutenberg as the most influential person during the millennium 1000-1999 AD.Gutenberg invented the movable-type printing press in the 1440’s. The Printing Revolution played a key role in the onset of the Renaissance, the Protestant Reformation, the rise in literacy, and the spread of ideas and learning throughout the world. The Bible in 1455 was the first book printed in mass quantities, and Christianity was forever changed. Prior to the printing press, the clergy of the Roman Catholic Church possessed most of the handwritten copies of the Bible. Parishioners didn’t read the Bible—their priests did. Sunday sermons were weekly tutorials teaching church-goers the lessons inside the Bible. As soon as the Bible was printed in large quantities, the masses had access to read the book themselves, and the masses had the opportunity to question the Catholic Church’s interpretations. In 1517 Martin Luther published The Ninety-Five Theses and nailed them to the door of the Wittenberg Church, a development acknowledged to have begun the Protestant Reformation, and the Catholic Church’s monopoly on Christian dogma was challenged.

Beginning in the 1990’s a comparable world-changing event occurred, as the widespread ownership of inexpensive and powerful personal computers allowed individuals to access the Internet. According to the Internet World Stats website in the 21 years since 1995, Internet use has grown 100-fold, and currently one-third of the world’s population has online access.

Just as the printing press made the Bible available to the masses, the Internet makes medical knowledge available to the masses. Prior to the Internet, medical knowledge was primarily confined to medical textbooks and journals, read exclusively by medical professionals. A few non-medical professionals wrote articles in magazines, newspapers, and encyclopedias to explain medical facts, diagnoses, and therapy to the lay public, but the overwhelming majority of the information was only presented to doctors and nurses in the form of medical books and journals.

The Internet has expanded the availability of medical information. Tens of thousands of medical websites exist, and laypeople surf the Internet for medical facts daily.  Bupa Health Plus  conducted a study in twelve countries, and found nearly 50% of the people seeking medical information on the Internet do so to make a self-diagnosis, and 75% of these individuals did nothing to check the accuracy of the online medical advice. In addition, some patients seek medical knowledge to decide whether they need to see a doctor or not.

Nowadays when patients arrive at a doctor’s office for an initial visit regarding a problem, it’s not uncommon for them to be armed with plentiful information on what their diagnosis might be, what their diagnostic workup should be, and what treatment options they want to have. Nowadays when patients arrive at the hospital for surgery, it’s not uncommon for them to be armed with abundant information on their disease, their pending operation, and even their anesthesia options.

Prior to the Internet, patients had to trust in the knowledge and experience of their doctors to direct the appropriate diagnostic and therapeutic regimen. Now it’s routine for patients to do their Internet homework before they see the doctor.

Some medical websites are invaluable. The National Library of Medicine website PubMed lists the abstracts of all medical publications online for free. Physicians can search by author’s name or other key words. Lay people can access and search medical information with this powerful tool as well.

Other websites are less reliable. There is no quality control regarding medical information on the Internet. Anyone can put medical information on a Web server, and the information posted may be incorrect or outdated. Medical websites may present fraudulent or deceptive information, often in an attempt to sell a product or a service. How can the public discern whether the medical information on the Internet is reliable? In his article Snake Oil: The Accuracy of Medical Information on the Internet Snake Oil: The Accuracy of Medical Information on the Internet, Dr. VN Reddy lists the following advice regarding choosing medical websites:

  1. Ask your doctor to suggest sites he or she thinks are well-written and accurate.
  1. Browse the medical professional organizations’ websites. For example, the American Society of Anesthesiologists or the American Academy of Pediatrics.
  1. Browse public-health websites, such as those by the Center for Disease Control, the World Health Organization, or the National Institutes of Health.
  1. Check each website you read for the author’s name and qualifications and the date when the page was last revised.

A  National Institutes of Health website identifies the following key points to determine whether an online source of medical information is reliable:

  1. Any website should make it easy for you to learn who is responsible for the site and its information.
  2. If the person or organization in charge of the website did not write the material, the website should clearly identify the original source of the information.
  3. Health-related websites should give information about the medical credentials of the people who have prepared or reviewed the material on the site.
  4. Any website that asks you for personal information should explain exactly what the site will and will not do with that information.
  5. The U.S. Food and Drug Administration and Federal Trade Commission are federal government agencies that help protect consumers from false or misleading health claims on the Internet.

The Internet is a valuable tool to expand your medical knowledge. I use it every day, and I probably learn more from the Internet than from any other source. However, this valuable tool must come with a disclaimer. In the 20th Century we were warned, “don’t believe everything you read in the newspaper. Today that advice can be expanded to “don’t believe everything you read on the Internet.” Read only reputable medical websites for your medical information, and above all, rely on your own doctor(s) to manage your medical problems.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

WAS JUSTICE ANTONIN SCALIA’S DEATH FROM OBSTRUCTIVE SLEEP APNEA?

THE ANESTHESIA CONSULTANT

Justice Antonin Scalia’s death was unexpected. I’ve never examined Justice Scalia, never had access to his medical records, and have no information other than what has been published over the Internet regarding the events of the last 24 hours of his life. According to published news reports, APNewsBreak: Justice Scalia Suffered From Many Health Problems, the Justice suffered from obstructive sleep apnea (OSA), chronic obstructive pulmonary disease, and hypertension.

220px-antonin_scalia_scotus_photo_portrait

As an experienced anesthesiologist, I’ve personally watched over 25,000 patients sleep during my career. Thousands of these patients carried the diagnosis of OSA. I’ve witnessed first hand what happens when a patient with OSA obstructs their airway and stops breathing during sleep.

Obstructive sleep apnea is a chronic condition of cyclic obstruction of the upper airway during sleep, usually combined with excessive daytime sleepiness and loud snoring.Apnea is the medical word for the suspension or stopping of breathing. Observation of at least five obstructive events (apneic events) per hour of sleep during a formal sleep study is a minimal criterion for diagnosing OSA in adults.

Let’s discuss a hypothetical male patient. He is 79 years old, overweight, and has a thick neck. Perhaps he is a Supreme Court Justice, and perhaps he is not. Because of his age and his body habitus, he’s at risk for the diagnosis of OSA, but we have no knowledge of any sleep study to document this.

We’re going to sedate this patient for a medical procedure. Intravenous sedative drugs will include some combination of a benzodiazepine such as Versed, a narcotic such as fentanyl, and a hypnotic such as propofol. The procedure does not require a breathing tube, so we’ll administer the sedation and be vigilant regarding what happens to the patient’s vital signs. As with all anesthetics, the patient will be fully monitored for heart rate, blood pressure, oxygen saturation, respiratory rate, and exhaled carbon dioxide level.

This is what happens when we administer strong sedatives to this hypothetical male patient who is 79 years old, overweight, and who has a thick neck:

  1. With the onset of sleep, the rate of breathing becomes slower and the volume of each breath decreases.
  2. Because of the decrease in ventilation, the oxygen saturation level will drop.
  3. As anesthesiologists, we administer oxygen via nasal cannula or via a mask, and the oxygen saturation will increase to a safe level again.
  4. If we progress to administering deeper sedation, the patient’s airway will obstruct. Typically this occurs because the base of the tongue drops back and occludes the airway, or redundant tissue in the oral pharynx relaxes and occludes the airway. With partial obstruction, we hear the patient snore, but ventilation continues. With total obstruction, the patient’s chest moves in an attempt to draw in a breath, but there is no ventilation through the obstructed upper airway.
  5. If this airway obstruction is not remedied, the oxygen saturation will drop below a safe level of 90%. At these low blood oxygen levels, the brain and heart will be deprived of necessary oxygen. A prolonged low blood oxygen level can lead to life threatening cardiac dysrhythmias or a cardiac arrest.
  6. With a physician anesthesiologist present, the airway obstruction is relieved by applying a jaw lift, extending the patient’s neck, inserting an oral airway, or inserting an airway tube.
  7. Without an anesthesiologist present, the patient could die.

In a related scenario, what if our hypothetical male patient who is 79 years old, overweight, and who has a thick neck doesn’t have medical sedation, but rather has a long busy day at 4,400 feet of altitude, and perhaps consumes alcohol with its attendant sedative effects, along with perhaps a sleeping pill or an oral narcotic analgesic taken to relieve the symptoms of a painful shoulder ailment? All of these factors (fatigue, altitude, alcohol, medications) serve to make a patient more sedated. Heavy sleep accompanied by snoring ensues. The partial airway obstruction of snoring progresses to the total airway obstruction of obstructive sleep apnea. The blood oxygen level drops, the heart is denied adequate oxygen delivery, and the patient suffers a cardiac arrhythmia and then a cardiac arrest.

Is this a “heart attack?”

Every one of us will die one day, and every one of our deaths will be accompanied by a heart that ceases to beat. The cause of the “heart attack” will differ for each of us. If someone has significant narrowing of a major coronary artery and attempts to run up a mountain, this event may increase the oxygen demand of the heart and precipitate a lethal heart rhythm. When a hypothetical male patient who is 79 years old, overweight, and who has a thick neck dies in the middle of the night, you can bet the cessation of the heart beat was due to airway obstruction and inadequate oxygen to the heart.

According to APNewsBreak, on the morning the Justice was found dead “a breathing apparatus was found on the night stand next to Scalia’s bed when his body was found, but he was not hooked up to it and it was not turned on.” Most likely this was a CPAP machine, or a Continuous Positive Airway Pressure machine. A CPAP machine includes a mask which the patient straps over their nose or over their nose and mouth prior to going to sleep. The CPAP machine delivers a stream of compressed air via a hose to the nose mask or the full-face mask, splinting the airway to keep it open under air pressure so unobstructed breathing becomes possible. The main problem with a CPAP machine is non-compliance, that is, the patient refuses to wear it. This was seemingly the case with Justice Scalia’s last night.

A take home message from this column is to respect the specter of OSA in your own life and in the lives of your loved ones. If you are a physician, respect the specter of OSA in your patients. Persons with an increased risk of OSA include people older than 60 years of age, patients with hypertension, prior strokes, heart failure, atrial fibrillation, obesity, or the metabolic syndrome including hyperlipidemia and diabetes. The most common symptoms are excessive daytime sleepiness and loud snoring. Persons who fit this profile should undergo a formal sleep study to screen for OSA. Most formal sleep studies require overnight monitoring of breathing patterns and oxygen saturation. The studies are not cheap, so screening every elderly obese snorer in America would be expensive. However, a diagnosis of OSA can lead to a cascade of effective therapies, including:  1) an oral orthodontic appliance to keep the jaw advanced, or 2) a continuous positive airway pressure machine to be worn while sleeping, or 3) airway surgeries on the palate, uvula, mandible, and/or maxilla, or 4) aggressive treatment of the OSA comorbidities of obesity, hypertension, and diabetes.

The American Academy of Sleep Medicine estimates that 25 million Americans may have OSA, and up to 90 percent of these patients are undiagnosed.

Questions will continue to swirl around the circumstances of Justice Antonin Scalia’s death. Was there a pillow over his head, as was first described by John Poindexter, the owner of the ranch who first discovered Scalia’s body? Were sedating medications or alcohol present in his bloodstream? Why did Presidio County Judge Cinderela Guevara pronounce Scalia dead of natural causes without even seeing the body? Why was no autopsy ordered? Was the Justice murdered, as if this was the plot of some John Grisham legal thriller?

We may never know the answers to these questions, but query most any anesthesiologist about the likelihood that OSA was involved in the death of Justice Antonin Scalia, and the answer you will get is . . .

“Yes, with a high degree of medical probability, obstructive sleep apnea is what killed Justice Antonin Scalia.”

DOES GENERAL ANESTHESIA CAUSE DEMENTIA?

Does exposure to general anesthesia cause dementia?

In a word, “No.”

dementia2075

A landmark study published in Anesthesiology Dokkedal U et al, Cognitive Functioning after Surgery in Middle-aged and Elderly Danish Twins. Anesthesiology. 2016 Feb;124(2):312-21  answers this question. Dokkedal studied 8,503 middle-aged and elderly Danish twins. Results from cognitive tests were compared in twins in which one sibling was exposed to surgery and the other was not. A history of major surgery was associated with a negligibly lower level of cognitive functioning, but there was no difference by interpair analysis, that is, when compared to their twin. There was no clinically significant association of major surgery and anesthesia with long-term cognitive dysfunction, suggesting that factors other than surgery and anesthesia, such as preoperative cognitive functioning and underlying diseases, were more important for cognitive functioning in mid- and late life than surgery and anesthesia.

(For readers who are not medical professionals, cognitive function includes reasoning, memory, attention, and language, the attainment of information and, thus, knowledge. Alzheimer’s disease and dementia equate to a chronic loss of these cognitive functions.)

Because Dokkedal’s study looked at a large number of patients, and each of these patients had a twin, it is considered a statistically powerful study.

A second recent study published in the same month, (Sprung J et. al., Association of Mild Cognitive Impairment With Exposure to General Anesthesia for Surgical and Nonsurgical Procedures: A Population-Based Study. Mayo Clin Proc. 2016 Feb;91(2):208-17)  examined 1731 Minnesota residents aged 70 – 89. Of these, 536 out of the 1731 developed Mild Cognitive Impairment (MCI) during a median follow-up of 4.8 years. All of their anesthesia records for surgeries after the age of 40 were reviewed. The authors found no significant association between the cumulative exposure to surgical anesthesia after 40 years of age and the development of Mild Cognitive Impairment.

In an editorial accompanying the Dokkedal study, (Avidan MS, Evers AS, The Fallacy of Persistent Postoperative Cognitive Decline, Anesthesiology. 2016 Feb:124(2);255-258.) Avidan and Evers wrote, “It is similarly tragic when adults older than 50 yr forego quality of life-enhancing surgery based largely on hypothesis-generating cohort studies and a post hoc ergo propter hoc fallacy dating to a 1955 report by Bedford in the Lancet, which suggested that persistent Postoperative Cognitive Decline was a concern following complaints from patients and their families regarding problems with cognitive function after surgery. . . . older patients should today be reassured that surgery and anesthesia are unlikely to be implicated in causing persistent cognitive decline or incident dementia.”

This editorial exposes the fallacy of post hoc ergo propter hoc, i.e. after this, therefore because of this, which has in the past led individuals to postulate that because a patient shows cognitive decline after surgery and anesthesia, that the cognitive decline must have been caused by surgery and anesthesia.

The authors of the editorial also admit that the first time detection of cognitive decline or dementia can be noted postoperatively for several reasons, including 1) cognitive decline or dementia are common in an aging population, approximately 50% of patients over the age of 60 undergo surgery, and the cognitive decline or dementia may first be detected at a time following surgery; 2) the preoperative trajectory of cognitive decline or dementia is rarely assessed, and postoperative cognitive decline or dementia is a continuation of the preoperative decline; 3) rapid onset cognitive decline or dementia can occur, and at times this decline will manifest and coincide with the time following surgery and anesthesia; and 4) it is difficult to change a firmly held conviction of past researchers, clinicians, and the general public that cognitive decline or dementia are caused by surgery and anesthesia.

The take home message is this: If you or one of your loved ones are over the age of 60 and need a surgical procedure to improve the quality of life, there should be no reluctance to have the surgery because of the fear of postoperative cognitive decline or dementia.

12 THINGS TO KNOW AS YOU NEAR THE END OF YOUR ANESTHESIA TRAINING

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

The most difficult challenge for any anesthesiologist is the transition from the end of anesthesia residency into the beginning of your first job. You’re on your at the hospital, sometimes on weekend nights, and sometimes at 3 a.m.

In “Subterranean Homesick Blues” Bob Dylan wrote, Twenty years of schoolin’ and they put you on the day shift. 

For anesthesiologists, it’s more like twenty-five years of training and they put you on the night shift. Alone.

bobdylanlookwiki

Every anesthesiologist walks a long road before they finish their education. This includes thirteen years to finish high school, four years of college, four years of medical school, a year of internship, three years of anesthesia residency training, and possibly an extra year of a subspecialty fellowship.

When I finished my training I was naïve about what was around the corner. I had no physicians in my family and no older physicians as close friends. I learned my lessons in real time on the front lines. As you near the end of that twenty-fifth year of education, here’s a list of twelve things you should know before you leave the cocoon of academia and venture out into the job market as an anesthesiologist:

  1. Your professors won’t find you a job. Their role is to teach anesthesia, to take care of patients, and to do research. They are not guidance counselors. Most of them are academics who either enjoy teaching or who enjoy the university faculty lifestyle. If they knew of or coveted a private practice job themselves, they would have taken one themselves long ago. You’ll likely have to find a job yourself. Your professors are of significant value when you are being considered for a specific job, because they can give your prospective employer a positive evaluation of you.
  2. You’ll find job listings on the Internet. Apply for jobs you have interest in. Don’t be surprised if most of these posted jobs have a problem such as low pay, an undesirable location, a dead end career track, or (let me say it again) low pay. The more jobs you look into, the better you’ll understand the marketplace. You’ll learn from every unsuccessful inquiry. Why are jobs posted on Internet sites usually inferior jobs? See #4 below.
  3. The best job opportunities are communicated by word of mouth. For example, imagine that an excellent group needs a new anesthesiologist with an emphasis in regional anesthesia. Members of that group will communicate with acquaintances at local university training programs or with top national university training programs, and ask for the names of recommended candidates. You want people to recommend you. It’s an old boy’s club of sorts (except that it includes men and women). You’ll get called up when the old boys agree that you’re the one they want.
  4. If there’s a hospital location or an anesthesia group you’re particularly interested in, but they are not advertising a job opening. don’t waste your time writing them a letter with your curriculum vitae attached. The letter will be discarded. Instead, make phone calls. Find out who the leader of the group is, and call the operating room or the anesthesia company’s phone number. If they are unavailable, leave a message. Repeat in a week or so until you make contact. If they never call you back, so be it. But if you apply this strategy to multiple different jobs, you will connect with a real human voice, and you’ll have the opportunity to sell yourself over the phone.
  5. Make as many personal contacts as you can with anesthesiologists who are already in private or community practice. Ask them questions when you can, and once you’ve landed a new job, connect with one of your new colleagues so they can serve as your mentor for the early career years. You’ll need to transition from a trainee mentored by professors to a graduated anesthesiologist mentored by a doctor who’s already out there in anesthesia practice.
  6. Retain at least one close contact with a former faculty member, so you can ask questions of them as well after you are out in community practice. The theme here is build bridges with new colleagues, and never burn bridges with your old teachers.
  7. You’ll have to pass your board examinations. My advice is to read every word of Miller’s Anesthesia prior to your oral boards. It’s a terrific book, and this is the one time in your career that you’ll be motivated to have encyclopedic knowledge of your specialty.
  8. Along with book learning, find opportunities to take mock oral exams from faculty at your training program. Stanford conducts twice-yearly mock oral exams, using the identical format that the American Board of Anesthesiology uses. See my column ADVICE FOR PASSING THE ORAL BOARD EXAMS IN ANESTHESIOLOGY. If you read Miller’s Anesthesia and undergo mock oral training, you’ll pass the board exams and you’ll become board-certified in anesthesiology—a requirement for all top shelf jobs.
  9. Think “Airway – Airway – Airway.” Airway –Breathing – Circulation, or A – B – C, describes the core management of critical care situations in the operating room, the emergency room, or the ICU. Of these three, the one that can get a new graduate (or any anesthesiologist) in a heap of trouble in less than five minutes is a botched airway. Be extremely careful and vigilant regarding all issues of airway management, both at times of intubation and extubation. Faulty judgment which leads to three minutes of hypoxia for your patient could severely harm your patient and change your life. Learn the ASA Difficult Airway Algorithm, and read AVOIDING AIRWAY DISASTERS IN ANESTHESIA. Avoid an airway disaster at all costs.
  10. Find a reliable recipe for each common type of anesthetic, hone it, and stick to it. The early career years are not about doing “interesting” anesthetics, they are about doing safe, predictable anesthetics with safe outcomes.
  11. Private practice surgeons are fast. Avoid the high doses of narcotics and muscle relaxants you used on those tediously long university cases. These will be overdoses in private practice, and your patients will be slow to wake up.
  12. Learn how anesthesia billing is done. Learn how money is distributed to new anesthesiologists in a prospective job, and how your income will change over the years at that job. A quality job will have a path to partnership, where you will earn as much as the senior members of the group do at this point in time.

 

Good luck, happy job searching, and may your patients all be safe!

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

THE ANESTHESIA CONSULTANT

What can we expect in the next 10 years of anesthesiology? What will be the trends for the future of anesthesiology? I’m writing this in January 2016. God willing, we’ll all be alive and well to reread this in 2026, and find out how many of these predictions about the future of anesthesiology came true.

mccoyvs20thcen

I’m writing this from the perspective of a busy clinician who has worked as an anesthesiologist in California in both private practice and at a major university hospital for over 30 years. I see 10 trends for the future of anesthesiology as:

  1. Lower income (as adjusted for inflation). There will be multiple causes for this: a) An aging population, with the significantly lower pay for attending to Medicare patients, b) Obamacare and other governmental payment cuts, c) Bundled insurance payments to hospitals, requiring anesthesiologists to negotiate for every nickel of that payment due to them, and d) Corporate anesthesia (see #9 below).
  2. More care team anesthesia and more Certified Nurse Anesthetists (CRNAs). Hospital systems will have increased incentives to perform anesthetics with cheaper labor. Rather than physician anesthesiologists personally performing anesthesia, expect to see CRNAs supervised by physician anesthesiologists in an anesthesia care team, or in some states, CRNAs working alone.
  3. There will be a paucity of new drugs to change the practice of operating room anesthesia. A few years ago I had a conversation with Don Stanski, MD, PhD, former Chairman of Anesthesiology at Stanford and now a leading pharmaceutical company executive, regarding new anesthetic drugs in the pipeline. Dr. Stanski’s reply was something along the line of, “There are almost no new anesthetic drugs in development. The ones we currently have work very well, and the research and development cost in bring an additional idea to market is high. Don’t expect much change in the coming years.” Consider sugammadex, a new drug for the reversal of neuromuscular blockade, recently approved by the Food and Drug Administration. The drug is more effective in reversing a rocuronium or vecuronium block than is neostigmine, but the cost is high. The acquisition cost of the smallest available vial of sugammadex is over $90, far exceeding the cost of neostigmine. In certain instances, faster reversal by sugammadex will be critically important, but for routine cases the cost is prohibitive. This trend of fewer new anesthesia drugs isn’t only a futuristic phenomenon. In my current private practice, I see my colleagues using the same medications that they used 25 years ago: propofol, sevoflurane, rocuronium, fentanyl, and ondansetron.
  4. An aging population, an increased volume of surgery, and an increased demand for anesthesia personnel. As the baby boomers age, there will be an increased number of surgeries on older, sicker patients. Anesthesia personnel will be in great demand.
  5. Anesthesiology will become more and more a shift-work job. A generation ago an anesthesiologist started a case and finished that case. An on-call anesthesiologist came to work at 7 a.m., took 24-hour call, and finished their last case as the sun came up the next morning. Certain instances of this model may persist, but as more anesthesiologist become corporate employees, expect more anesthesia practitioners working 8-hour or 12-hour shifts, just like employees in other jobs.
  6. Increased interest in the specialty of anesthesiology amongst medical students. Although several items on my list may seem discouraging, take heart, because the career of anesthesiology will remain extremely popular. Why? Because the other fields of medicine have problems, too. Bigger problems. Many future doctors will shun the primary care fields of family practice, internal medicine, and pediatrics. The primary care fields offer long days in clinics, dealing with a new patient every 10 – 15 minutes, and they suffer from low pay. Because of the higher reimbursement in procedural specialties, careers in surgery, anesthesia, cardiology, and invasive radiology will always be popular.
  7. Expect improved safety statistics regarding anesthesia mortality and morbidity. Anesthesia has never been safer. See “How Safe is Anesthesia in the 21st Century?” Expect further improvements in monitors, protocols, education, and the analysis of Big Data that will make anesthesia safer than ever.
  8. There will still be a non-zero incidence of anesthesia-related fatalities. There will still be disasters, particularly airway disasters. Some anesthesia clinical situations will always remain extremely difficult and challenging, and human error will not be eradicated.
  9. Large national corporations will continue buying up private anesthesia practices, perhaps eliminating the current model in which groups cover one hospital or one city alone. In the last three months, Sheridan, the physician services division of AmSurg, Corp has purchased the 60-physician, 140-anesthetist Northside Anesthesiology Consultants in Atlanta, and the 240-physician Valley Anesthesiologists & Pain Consultants in Phoenix. In these purchases, senior board members and partners receive seven-digit checks to sell their practice, then all physicians in the practice’s future labor for a discounted wage, perhaps as low as 50% of the prior income. If this trend becomes widespread, this subset of the anesthesia workforce will become low paid practitioners, while the purchasing corporations will make significant profits for their stockholders.
  10. Continued fascination with anesthesia practice, a discipline which makes all surgical treatments and cures feasible. Without anesthesia, there can be no major surgical procedures. Medical care without major surgical procedures is unthinkable. Whether as anesthesia providers, as patients requiring surgery, or just as observers of the process, we will all continue to value and marvel at the field of anesthesia.

ARE OLDER ANESTHESIOLOGISTS LESS SAFE?

THE ANESTHESIA CONSULTANT

Do you want an older anesthesiologist only months from retirement? Do you want a young and inexperienced anesthesiologist? Is there any data to help answer these questions?

200216109-001

You’re boarding a commercial aircraft. It’s raining hard outside, and visibility is limited. You catch a glimpse of the pilots in the cockpit. To your relief, both of them are gray-haired. You’re nervous, and you don’t want a young and inexperienced pilot.

How do you feel when you meet your anesthesia provider prior to a surgical procedure? Do you want a young and inexperienced anesthesiologist? Do you want a geriatric anesthesiologist only months from retirement? Is there any data to help answer these questions? This topic was reviewed in a recent issue of Anesthesiology News (December 2015, Volume 41:12).

In an abstract presented at the 2015 American Society of Anesthesiologists annual meeting, data from the 2014 National Anesthesia Clinical Outcomes Registry was compiled for every anesthesiologist of known age who performed at least 100 cases. (Chen LC, et al, Abstract A1012). The anesthesiologists were divided into three age groups: less than 45 years (36%), 45 – 54 years (31.5%) and 55 years and older (32.4%). There were nearly 4 million cases from 5,334 providers. The overall mortality rate was 3.6 per 10,000 cases.

There was no mortality difference related to the anesthesia provider’s age. Higher ASA physical status (i.e. sicker patients) was associated with poorer outcomes. ASA Physical status 4 and 5 patients were more likely to die compared to ASA status 1 – 3 patients.

The study also examined practice patterns, and significant differences were discovered. Older anesthesiologists were:

  1. More likely to perform anesthetics under monitored anesthesia care, and less likely to perform regional, spinal, or epidural anesthesia.
  2. Less likely to work evenings, weekends and holidays.
  3. More likely to work part-time, and with a nurse anesthetist care-team delivery system.
  4. More likely to do outpatient cases and nonsurgical obstetrical/gynecology cases.
  5. More likely to perform shorter surgical cases and be involved in simpler surgeries with lower base units.

Major complications occurred at a rate of 18.4 per 10,000 cases. The middle-aged group (provider ages between 45 and 54) had more major complications compared with older anesthesiologists. The authors believed that elevated ASA physical status played a part in this statistic, because the middle-aged anesthesiologists took care of sicker patients. The middle-aged anesthesiologists were also more likely to care for inpatients under general anesthesia for longer cases, and these longer cases resulted in more major complications.

In a separate study on the topic of aging anesthesiologists in Canada, a survey found 7% of Canadian anesthesiologists were aged 65-74 years, and 3% were older than 74 years old. Anesthesiologists older than 65 years in the provinces of Ontario, Quebec, and British Columbia had 50% more cases involving litigation and almost twice the number of cases involving severe patient injury, compared with anesthesiologists younger than 51 years of age. The authors of this paper proposed regulations to include: no further on-call duties for those aged 60 and older, no further high-acuity cases for those aged 65 and older, and retirement from operating room clinical practice at age 70. (Baxter AD, The aging anesthesiologist: a narrative review and suggested strategies. Can J Anaesth. 2014 Sep;61(9):865-75.)

A 2006 United States survey of physicians aged 50-79 years showed that the work week of anesthesiologists decreased with advancing age, and part-time work increased. (Orkin FK, et al. United States anesthesiologists over 50: retirement decision making and workforce implications. Anesthesiology 2012 Nov;117(5):953-63.)

I’m currently in the higher of the three age groups (age 55 years and older). In my years as an anesthesiologist, I’ve watched colleagues of my generation change their clinical workload in a pattern consistent with the data presented above. As anesthesiologists age, most of us do not desire to be working at 3 a.m. resuscitating trauma patients, or doing anesthesia for 24-hour liver transplantation cases. These are surgeries for younger anesthesiologists. The overwhelming majority of aging anesthesiologists migrate toward administrative roles, daytime work, patients who are less sick, and simpler surgeries that minimally alter a patient’s physiology.

In the United States the mandatory retirement age is 65 for commercial pilots. There are no rules or regulations that prohibit an anesthesiologist from working at any particular advanced age. Could an 80-year-old anesthesiologist give you a safe anesthetic? It depends. If the 80-year-old has a valid medical license, a valid certificate from the DEA (Drug Enforcement Agency), and medical staff privileges at the facility your surgery is scheduled for, then he or she could work there. You can expect the 80-year-old will fare much better on simple outpatient anesthetics, and will never be doing open heart surgery or brain surgery anesthetics.

The hospital I work in at Stanford University confronted this issue in 2012 by enacting a Late Career Practitioner Policy. Physicians aged 75 and older are required to undergo a physical examination, cognitive screening, and a peer assessment of their clinical performance. These evaluations must be completed every two years to retain hospital privileges. Stanford is one of very few academic medical centers to require this scrutiny regarding older practitioners, and the policy met significant resistance from medical staff members prior to the policy being passed and enacted.

It is my impression, based on my clinical career, my peer review work, and my expert witness work on medical malpractice cases, that newly trained and inexperienced anesthesiologists present an increased risk for patient complications and poor outcomes. During anesthesia residency there is always a faculty member nearby to save an inexperienced anesthesiologist when he or she gets into a clinical problem. After that inexperienced anesthesiologist graduates and transitions into a community clinical practice, they may have to care for a sick patient at 3 a.m. as the solo on-call anesthetist, or they may have to manage an emergency airway disaster by themselves. Will they think clearly under pressure and make correct decisions to prevent their patients from dying? Every new graduate has these fears regarding their transition to post-residency practice. There’s nothing like having a couple of years of practice experience and 1500 solo cases under your belt to make you a safer anesthesiologist.

Expect to see further research on the topic of an anesthesiologist’s age in the years to come. Older physicians have a wealth of experience, but may have geriatric limitations on their ability to safely care for patients. Younger anesthesiologists have limited experience, and may be at increased risk for complications and mortality. Further Big Data from the National Anesthesia Clinical Outcomes Registry will help answer these questions in the future. As of now, there is no convincing data that practitioners at either extreme of age present a risk factor.

THE ANESTHESIA CONSULTANT

You’re scheduled to anesthetize an NFL quarterback for a shoulder arthroscopy and rotator cuff repair. The patient earns $25 million dollars per year for throwing footballs. Would you feel comfortable inserting a needle into his neck to do a regional anesthetic? Would you feel comfortable doing an interscalene block on an NFL quarterback as part of his anesthetic?

0122667001423075661_filepicker

Regional anesthesia is a growing frontier in modern clinical anesthesia, in part because of the availability of ultrasonic imaging to help us direct needle placement. The subspecialty of regional anesthesia has blossomed. Listening to some of its disciples, it would seem that nearly every orthopedic surgery procedure can benefit from an ultrasonic regional block for intraoperative and postoperative pain control.

Anesthesiology News (Hardman D, July 2015, 41:7) recently reviewed the topic of nerve injury after peripheral nerve block. Data shows that the risk for permanent or severe nerve injury after peripheral nerve blocks is low. Per the article, the prevalence of permanent injury rates as defined by a neurologic abnormality present at or beyond 12 months after the procedure, ranges from 0.029% to 0.2%.

Low, but not zero.

There is a high incidence of temporary postoperative neurologic symptoms after arthroscopic shoulder surgery, whether the patient received a regional block or not. The incidence of temporary neurologic symptoms during the first week ranged as high as 16% to 30%. Most of these involved minor sensory symptoms such as paresthesias and dysesthesias.

An incidence of 16% to 30% is a remarkably high number.

Data from a clinical registry at the Mayo Clinic for total shoulder arthroplasty from 1993 to 2007 demonstrated a peripheral nerve injury rate of 3.7% following general anesthesia in contrast to a peripheral nerve injury rate of 1.7% in patients who received an interscalene block (Sviggum HP, et al. Perioperative nerve injury after total shoulder arthroplasty: assessment of risk after regional anesthesia. Reg Anesth Pain Med. 2012;37:490-494). It’s striking that the patients with general anesthesia had MORE peripheral nerve injuries than patients who had an interscalene block.

Over 97% of the patients who developed peripheral nerve injury recovered completely or partially at 2.5 years after the procedure. Seventy-one percent experienced full recovery, which means that 29% did not experience full recovery.

Given this information, would you give the NFL quarterback a general anesthetic or would you include an interscalene block?

I submit that no anesthesia provider should feel comfortable inserting a needle in the neck of this $25 million-dollar-a-year man. No anesthesia provider should feel comfortable doing an interscalene block for his shoulder arthroscopy. Why not? Even though the above data show that peripheral nerve injury can occur following shoulder arthroscopy with either general or interscalene anesthesia, the anesthesiologist will likely be sued only if he or she performs the interscalene anesthesia.

A plaintiff lawyer will be quick to link the needle in the patient’s neck to the nerve damage, if the damages are the NFL player’s inability to earn his $25 million per year, and the anesthesiologist will be sued. If there is peripheral nerve injury following a general anesthetic, expect the surgeon to be sued.

With peripheral nerve injury following general anesthesia, the surgeon will incur the medical malpractice risk because shoulder arthroscopy has its own risks for nerve injury. Risks include: 1) traction on the brachial plexus due to positioning during surgery, 2) irrigating fluid extravasation causing tissue edema compressing the brachial plexus and peripheral nerves, or 3) arthroscopic portals damaging nerves.

Ultrasound-guided blocks have many advantages, but there is no sufficient evidence demonstrating a lower neurologic complication rate with this technique.(Liu SS, et al. A prospective, randomized controlled trial comparing ultrasound versus nerve stimulator guidance for interscalene block for ambulatory shoulder surgery for postoperative neurological symptoms. Anesth Analg. 2009;109:265-271).

If the risk of a limb-harming peripheral nerve injury is prohibitive for an NFL player, why is the risk acceptable for the rest of our patients? Is it because an accountant or a fireman who is a recreational tennis player or golfer is less likely to sue the anesthesiologist if a peripheral nerve injury occurs?

A 2007 survey of academic regional anesthesiologists indicated that nearly 40% of respondents did not disclose the risks of long-term and disabling neurologic injury prior to performing peripheral nerve blocks. (Brull R, et al. Disclosure of risks associated with regional anesthesia: a survey of academic regional anesthesiologists. Reg Anesth Pain Med. 2007;32:7-11)

It’s more difficult to sell an “optional” peripheral nerve block if you disclose to the patient the risks for long-term nerve damage. However, if you do not disclose the risks of long-term nerve damage, you will be vulnerable to a lawsuit should nerve damage occur.

We’ll need to review the anesthesia closed claims data for peripheral nerve injuries in five or ten years time to see how many successful lawsuits were generated by the current crescendo in the performance peripheral nerve blocks. Until that time, I recommend honest and complete informed consent to all your patients regarding the non-zero risks of permanent nerve damage related to peripheral nerve blocks.

THE ANESTHESIA CONSULTANT

I’m not a fan of the current state of Electronic Health Records (EHR), also known as Electronic Medical Records (EMR). Particularly in acute care, the computer keyboard and screen have no place between an anesthesiologist and his patient, an emergency room physician and his patient, an ICU doctor and his patient, or an ICU nurse and her patient. In a past column I identified the EHR as the most overrated advance affecting anesthesia practice in the past 25 years. ZDoggMD trashes EHR in his powerful and humorous You Tube video An EHR State of Mind, in which he raps about Electronic Health Records to the tune of Jay Z’s and Alicia Key’s hit single An Empire State of Mind.

ZDoggMD is a former Stanford physician known for his music videos, parodies, and comedy sketches regarding contemporary medical issues and work in the medical field. ZDoggMD is played by Dr. Zubin Damania, CEO and Founder of Las Vegas-based Turntable Health. Dr. Damania attended UC Berkeley in the early 1990s, followed by medical school at UCSF and residency at the Stanford University School of Medicine.

Check out his website at http://zdoggmd.com. Links exist to multiple equally funny satiric videos. You’re sure to be entertained.

I agree with him that the current cumbersome EHRs come between doctors and patients during hospital care. My criticisms include:

  1. Different EHRs at different hospitals are unable to communicate with each other.
  2. If you work at different hospitals with different EHRs, you have to be trained and retrained in multiple EHR platforms.
  3. With an EHR it takes at least 5 clicks to chart “atropine 0.4 mg.” In the past with a paper record you would merely write “0.4” on the atropine line.
  4. Nurses consistently have their backs to patients as they type, type, type data into computer terminals. In an operating room, the circulating nurse’s job is analogous to that of a court reporter/stenographer. Florence Nightingale would have had a stroke.
  5. As ZDoggMD points out in his video, the current EHR is a “glorified billing platform with some patient stuff tacked on.” Hospitals spend hundreds of millions of dollars to install the EHR, and then tell us that the EHR will help them bill and collect money at a superior rate. The economics don’t add up, and have nothing to do with patient care.
  6. With an EHR, instead of writing a pertinent note at each patient encounter, health care providers copy and paste previous notes, altering the minimal differences at each encounter. This habit makes it difficult to ferret out the pertinent information in, for example, a six-page copied template.

ZDoggMD challenges us as healthcare providers. On his website he writes, “We on the front lines of healthcare need to stand up and demand that our organizations, government, and tech vendors stop letting the unintended consequences of legislation and technology wreck our sacred relationship with patients while destroying our ability to do what we do without having to tell our kids to stay as far away from medicine as they can. Great technology [insert Steve Jobs fanboy comments here] can be the glue that connects us…”

Indeed, I wish Apple Computers would create an EHR which was as intuitive and easy as their iPad software.

Perhaps in the future the state of mind of an EHR will be superior. As of now, as ZDoggMD points out, it is not.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

THE ANESTHESIA CONSULTANT

6) MR. DYLAN’S BLUES

Johnny and I ate breakfast together at 6:30 a.m. It was a complex meal—we split a six-pack of powdered sugar donuts from the Seven-Eleven and washed them down with two glasses of orange juice. The talc-like sugar dusted Johnny’s upper lip and the collar of his San Francisco Giants T-shirt. The kitchen was quiet as a library. The only sounds were our glasses clacking against the tabletop. It was Johnny’s first day of school and my first day to report to the local hospital. We were each journeying into the unknown, and the tension connected us.

I broke the silence. “Nervous?” I said.

“Nope.”

I didn’t believe it. Johnny’s eyebrows cast dark shadows, shielding his sunken eyes in blackness. I waited a minute for a sequel to his monosyllabic teenage offering, but no conversation followed.

“Want me to walk over there with you?” I said. “Make sure the paperwork is all OK for your transfer?”

Johnny scoffed. “Are you kidding? I’m 17 years old, Dad, not 7. I’ll figure it out.” He pushed away from the table and left the kitchen. I watched him pace back and forth across the living room floor like a skydiver awaiting his turn to jump out of the plane. Then he grabbed the front door knob and said, “I hope this school doesn’t suck, for both of our sakes.” The door slammed shut, and I looked out the front window to see Johnny hopping through last night’s frozen footprint holes in the snow. Steam rose from his wet hair. He wore a fleece turtleneck over a pair of cotton sweat pants, and no gloves, hat, or boots. I watched him bound two stairs at a time up the entryway of Hibbing High School.

I needed to be at Hibbing General Hospital before 7:30. I’d filled out all the necessary paperwork online. I’d already secured my medical staff privileges and my appointment to the anesthesia service. I wanted to arrive early to check out the facilities and meet the people I’d be working with in the coming months.

I dressed myself in a pair of Sorel boots, a North Face jacket, and one of Dom’s Minnesota Vikings knit caps. A puff of wind from the north scorched my face as I headed out into the winter morning. The stark chill woke me up faster than two espressos. The hospital was a three-block hike from Dom’s house, so it made sense to leave the battered BMW on the curb and walk to Hibbing General.

The hospital was an aging three-story building made of yellowed stone. The front doors were tall brown slabs flanked by two white Doric columns. I smiled at the polished surface of the brown wooden doors. I’d worked summers as a maintenance helper at the General during my college years. One day my foreman gave me a can of red paint and told me to paint these very doors. The next day the hospital administrator chewed our heads off for painting the hospital front doors the color of blood. He dispatched me to the front of the building with a paintbrush and a gallon of brown paint. The doors were still brown this very day.

I found the surgical locker room, a small space one-tenth the size of the men’s locker room at Stanford. I selected a set of scrubs off the shelf and changed out of my street clothes. At Stanford the scrubs were bright royal blue. In Hibbing the scrubs were faded green and looked like they’d been in use since the day I was born in this very building.

I was edgy, even though I was overqualified to work at this little community hospital. At Stanford every nurse, doctor, and janitor knew my name. Here I’d have to earn the respect of dozens of people who’d never heard of me. Medical careers don’t travel as well as business careers. A businessman in California could be promoted to a CEO job in Minneapolis, but doctors who moved from one state to another started at the bottom of the ladder, behind physicians who had reputations and referral patterns already established in the new community.

I entered the hallway of the operating room complex. Hibbing General had only six operating rooms, compared to the 40 rooms at Stanford. The schedule for the day was posted on a white board across from the central desk. My old med school classmate, Michael Perpich, the Chief of Staff at Hibbing General, was the surgeon working in operating room #1. Dr. Perpich was repairing an inguinal hernia on a 43-year-old man—a routine case. I could pop in and say hello without distracting Perp from his task.

I put on a surgical hat and mask and pushed open the door into O.R. #1. The operating room was small, a compact 30 feet by 30 feet. The linoleum floor showed brown stains from old iodine spills. The faded turquoise tile on the walls had witnessed thousands of hernia surgeries. Michael Perpich was bent over the patient’s abdomen. He saw me walk through the door, and said, “Nico Antone. The Tone. Get your ass over here.” A surgical mask covered his face, but I knew my friend was grinning.

“They said you needed some help to fix this hernia,” I said.

“You’re a God damned gas-passer. You couldn’t fix this hernia if I held the book open for you.”

“I’m here to see if your hands shake as much as they used to, Perp.”

“I came here straight from the card room at the Corner Bar at dawn. Never felt better.”

“You’re so full of shit.”

“Did you guys get situated over at Dom’s?”

“We did. Johnny wasn’t thrilled about waking up at 6 a.m., but he ran up the high school steps two at a time this morning.”

“So he’s a gunner. Just like his dad.”

“I got by.”

“You opened a textbook once a week in med school, and you still finished number one in our class. I can’t believe you came back. When you left for California you said never wanted to see a snowflake again.’”

“Things change, Perp. My kid needs an upper-Midwest high school diploma.”

“California kid comes to the wilderness to go to the head of the class, eh? I’ll tell you one thing: the Hibbing teachers will shape him up. I had sergeants in the Army who were more mellow than the Hibbing faculty.”

The scrub tech, a blonde woman wearing too many layers of blue eye shadow, said, “My son is a sophomore. He studies four hours every night.”

“Nico, meet Heidi, my right-hand woman,” Perpich said. “She’s my assistant, my psychotherapist, and the encyclopedia of all gossip great and small in the village of Hibbing.”

“Nice to meet you,” I said.

“Heidi, this is Dr. Nicolai Antone, a welcome addition to the anesthesia staff. Dr. Antone and I went to med school together. He was an anesthesiologist in California, but now he’s one of us, the slightly-better-than-average staff of Hibbing General. So you left Alexandra behind?”

“I did.”

“Good move. Not much up here for princesses.”

“You’re married, Dr. Antone?” Heidi said.

“I am. My wife is back in California.”

She fluttered mascara-laden eyelashes at me and said, “Welcome to Hibbing General. I look forward to working with you.”

Perpich looked up toward the head of the operating room table and said, “Bobby, did he get his antibiotic?”

A wisp of a man—narrow and bony—stood at the head of the operating room table in the anesthesia cockpit of machines, monitors, intravenous drips, and drug cabinets. The man said, “She did. One gram of Kefzol at 7:45.”

“Nico, I want you to meet Bobby Dylan, our Director of Nurse Anesthesia,” Perpich said.

My head snapped back. I wondered if I trusted my ears. Bobby Dylan? The same name as the legendary musician? Here in Hibbing?

The nurse anesthetist ignored Perpich’s cordial introduction and said nothing to me. I was miffed. Who did this guy think he was? He was only a nurse anesthetist. Why the ingratiating attitude toward me, a board-certified anesthesiologist physician?

It was a small hospital, and despite my negative first impression I felt compelled to meet my fellow anesthesia colleague. I walked around the operating room table and entered the anesthesia station. A blue paper hat and mask covered Dylan’s face. His sole facial features were the recessed caves that housed his glossy fish eyes, and the speckled black and gray eyebrows that floated above them.

I extended my hand and said, “Greetings. I guess we’ll be working together.”

Dylan turned his back on me. The beep, beep, beep of the patient’s pulse rate hung between us. He reached over and turned the knob on the anesthesia machine that titrated the oxygen flow. He coughed twice—loud, harsh, barking sounds, and said, “We opted out here, Mac.”

“What?” I said. I wasn’t sure what I had just heard.

“We opted out,” Dylan repeated. He still wasn’t looking at me. He picked up his clipboard and made some notations on the patient’s chart with a pen.

I was getting more and more pissed off. My first impressions were confirmed. This guy was a dick. I didn’t care if this was Dylan’s anesthetic, his operating room, and his hospital. I was unaccustomed to this degree of condescension within two feet of an anesthesia machine. He turned up the intravenous propofol infusion and continued to ignore me, even though I was close enough to smell the staleness of his body odor.

I checked the settings on the anesthesia machine and monitors, looking for some sign that Dylan was as incompetent as an anesthetist as he was as a conversationalist. He was using routine concentrations of standard anesthetic drugs. The ECG, blood pressure, and oxygen saturation numbers all showed normal values. Dylan wasn’t a doctor, but at the moment he was delivering a routine anesthetic in a safe fashion.

I thought to myself, Fuck you, you dirtball. If this Bobby Dylan character wanted to be left alone, I was going to leave him alone. I said, “Hey Perp, I’ll catch you when your case is done, OK?”

“Will do. I’ll meet you in the lounge. Give me 30 minutes.”

“See you there.” My feathers were ruffled. It was great to see Michael Perpich again, but if my initial contact with this nurse anesthetist was any indication, my welcome in the Hibbing medical community was going to be as chilly as a January dawn. I made my way to the operating room lounge, a stark room with four walls of undecorated peach-colored wallboard. The sole furnishings were two long tables and a dozen chairs. All the chairs were empty. Sections of the Duluth News Tribune and the Hibbing Daily Tribune were strewn over the tabletops. The aroma of fresh brewed coffee filled the air. I poured myself a cup and selected a glazed doughnut from a platter.

I felt like a midcareer misfit, stuck in somebody else’s workplace. I missed Stanford. On a professional level, this move to Minnesota looked to be a near-death experience for me.

Michael Perpich’s clogs hammered the floor when he walked in. He pinched the back of my neck, snatched two doughnuts for himself, and plopped down in a chair across from me. “It’s great to see you, Tone,” he said. “I still can’t believe it.”

I hadn’t sat eye to eye with Perp for years. With his surgical cloaking removed, he looked ten years older than me. The top of his head had more dandruff than hair, and the creases around his nose and mouth were deep and long. His smile was genuine, and I chose to disregard the ancient appearance of the only acquaintance I had within a thousand miles.

“Glad you’re here,” I said. “I’m counting on you to be my lifeline at this place.” I waved my hand at the desolate room. “Does anybody else work here?”

“Of course. We have a full staff, like any other community hospital, but we’re light on anesthesiologists. Your timing is perfect. Our last two anesthesiologists retired and moved to the Sun Belt in November. We have six nurse anesthetists, but for tough cases we need an M.D. anesthesiologist in town. Now we’ve got you.”

“So the rest of the anesthesia staff is all nurses?”

“Yep. Six nurse anesthetists. They’re a solid group. I haven’t had too many problems with them.”

I was unconvinced. Nurse anesthetists were registered nurses with a year or more of intensive care unit experience, followed by two or three years of training in a nurse anesthesia program. They learned how to anesthetize patients, but they weren’t medical doctors. In some hospitals, anesthesiologists worked with nurse anesthetists in anesthesia care teams, a team model in which one M.D. anesthesiologist might supervise four nurse anesthetists working in four separate operating rooms. Because this hospital had no anesthesia doctors, the nurse anesthetists were working unsupervised.

“What’s the deal with the Bobby Dylan guy?” I asked. “He stopped one step short of open hostility. Is he a prick, or what?”

“Sometimes he is.”

“He didn’t give me the time of day.”

“It’s a turf thing. This is his hospital. You’re an outsider. The guy doesn’t want you here.”

“He’s a nurse. How does he get off giving me a hard time?”

“Minnesota is an opt-out state, Nico. The Minnesota governor opted out of the requirement for a medical doctor to supervise nurse anesthetists. Bobby Dylan can give anesthesia here, just the same as you can, even though he’s not a doctor.”

We opted out here, Mac. The words Dylan had uttered to me. Opted out.

“So it’s legal here for a nurse anesthetist to give an anesthetic without being supervised by a physician?”

“That’s right.”

“That’s substandard care, if you ask me, and it still doesn’t make this Bobby Dylan guy a doctor. If you had enough physician anesthesiologists in town, would you still let jokers like him give anesthetics alone, or would you replace him with a doctor?”

Perpich threw up his hands. “That’s never going to happen, so who cares? Dylan has been here a long time. He hasn’t had any deaths, he’s kept his nose clean, and he’s not going anywhere.”

“Why is he named Bobby Dylan? That can’t be for real.”

Perpich shrugged again. “I don’t know what his real name is, and I don’t care. He showed up in Hibbing 8 or 10 years ago, and his license and paperwork all identified him as Bobby Dylan. I asked him if that was his real name or if he’d changed his name.”

“And he said?”

“He said his name was Bobby Dylan. Period. He dodged any questions about his past. He was a nurse anesthetist in the Afghanistan War. He’s got a wife and a daughter. He plays guitar and sings at a bar downtown. Plays all the original Dylan songs. People tell me he’s pretty talented. Maybe he was a huge Bob Dylan fan and he just wanted to move to Dylan’s hometown, take Dylan’s name, and get a job here. If so, he’s done all three.”

I shook my head. “That’s pretty weird stuff.”

“It gets more weird. He bought the old Zimmerman house.”

“You’re kidding.”

“Nope.”

“He’s a psycho,” I said.

Perpich’s eyes twinkled. “Up here, there are a lot of characters. Get used to it. He’ll grow on you, once you accept the fact that he’s your peer.”

“My peer? I’ll never accept that.”

As if summoned by their conversation, Bobby Dylan came in through the doorway, poured himself a cup of coffee, and sat in the opposite corner of the room. He peeled off his surgical hat to reveal a fuzzball of curled black and gray hair. He took out a pen and started filling out a crossword puzzle from the morning paper. His mouth stretched into a long yawn. It was just another day for him. My presence was of no consequence.

“I’m going to make rounds on my patients upstairs on the surgical wards,” Perpich said. “Will you be home tonight?”

“Where else would I be?”

“I’ll drop by. I’ve got some housewarming presents for you.”

“I hope it’s a digital video recorder. Dom doesn’t have one.”

“No DVR. Just make sure you’re hungry.”

“Sounds good. See you later.”

Right after Perpich left, I heard a rumbling voice behind me say, “Doctor Antone?”

I turned. It was Mr. Dylan. His facial expression was a cross between a smirk and an all-knowing smile.

“Yes?” I said, puzzled at the encounter.

“I dissed you back there in the operating room. Sorry about that. I was concentrating on my patient, and no one told me you were coming to town. I expect this place is big enough for both of us. No hard feelings?”

I was suspicious. The curl of Dylan’s upper lip seemed to say, I don’t like you one bit, but I’ll pretend that I do just to fuck with you. Before I could answer, he sat on the tabletop in front of me and asked, “Why does a California guy like you move to the Iron Range?”

“I grew up here. I missed the ice fishing and deer hunting.”

“Bullshit.”

“My son transferred into the 11th grade. We want him to graduate from Hibbing High.”

“Let me guess. You think he’ll be the smartest kid in town.”

“I have no idea. We just got here.”

Dylan twirled a wisp of his moustache between his fingers and thumb. “I’ll bet $1000 you and your kid are gone by next January. This ain’t no place for boys from Californ-eye-aye. No place at all.”

“We’ll adjust.”

“You OK working here, where nurse anesthetists are your equals?”

I bit the inside of my cheek. “I’m not sure nurses and doctors are equal. I expect I’ll get used to the fact that nurses can give their own anesthetics here.”

“Of course you will. Just remember, you’ve got no power over me here. No power at all.” Dylan winked and said, “Now, if you’ll pardon me, I’ve got to go make me some money.”

He walked away, and his words echoed in my ears: No power over me at all. My first impression was reconfirmed. This Bobby Dylan was trouble.

It was break time, and the lounge was filling up. An attractive woman sat down at the adjacent table. She had the palest of green eyes that precisely matched the color of her scrub shirt. She had flawless skin and adorable dimples, and the knack of smiling nonstop as she chatted.

I smiled to myself, and forgot about the onerous Mr. Dylan. The sight of a beautiful woman trumped all of life’s ills.

It really did.

AN ANESTHESIA PATIENT QUESTION: “WHY DID IT TAKE ME SO LONG TO WAKE UP AFTER ANESTHESIA?”

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Patients sometimes say, “Why did it take me so long to wake up after anesthesia?” when they discussed their previous anesthetic history. They are fearful that something is wrong with them, and they will always have delayed awakenings.

 

Certain patients have consistent bad experiences from a past general anesthetic. A previous anesthetic left them somnolent all day after surgery, and/or they felt sleepy or ill for days after a previous surgery. They wonder if they are at increased risk for anesthesia, if something went wrong in their past anesthetics, and whether they can do about it.

Whenever a patient tells me they’ve been very sensitive to anesthesia in the past, they’re always right. The good news for patients is: you probably can do something to help yourself in the future.

The most valuable thing you can do is obtain a copy of your previous anesthetic record and Post Anesthesia Recovery Room records from a surgery in which you had a perceived prolonged wake up. Save these documents and present them to future anesthesiologists. Inform future anesthesiologists regarding your history of prolonged sedation, and they can make adjustments in their drug delivery and techniques to attempt to avoid the same problems. Future anesthesiologists can administer lower doses of medications or fewer medications as they deem advisable.

The world’s foremost anesthesia textbook, Miller’s Anesthesia, does not have a specific section or chapter on the topic of avoiding prolonged wake ups. If you search the Internet or the PubMed website for a discussion of the topic “prolonged awakening from anesthesia,” you’ll find a shortage of useful information. Few papers have been published on the topic.

But every case of prolonged wake-up has its own story. General anesthetics and sedative drugs work by anesthetizing the brain and central nervous system. Based on thirty years as an anesthesiologist, the personal administration of 25,000+ anesthetics, and information from medical textbooks, what follows are lists of the primary factors which cause prolonged sedation after anesthesia.

Patient characteristics that correlate with prolonged awakening after anesthesia:

  1. Patients with a past history of slow awakening from anesthesia.
  2. Patients who are naïve to central nervous system depressants in their weekly life. That is, they never or very rarely drink alcohol, and never take sedating medications of any kind. Chronic alcohol consumption increases the dose of propofol required to induce loss of consciousness (Fassoulaki, A et al. Chronic alcoholism increases the induction dose of propofol in humans.Anesthesia and Analgesia. 1993;77(3):553-556). Conversely, patients who have zero or modest exposure to drugs like alcohol can require lower doses of anesthetic drugs.
  3. Patients who claim they are “sensitive to all medicines.”
  4. Elderly patients. As you age your ability to metabolize medications decreases. Older persons, especially those over the age of 70-80 years, require lower doses.
  5. Obese patients. Intravenous doses of medications are calculated according to a patient’s weight, but this number should be their lean body weight, not their weight including excess fat. Imagine two patients who are the same age and height, but one weighs 150 pounds and the second weighs 300 pounds. The second patient will need higher doses than the first, but will not require twice the dose. Markedly increasing the weight of fat cells does not mean the brain needs twice the dose of medications.
  6. Petite patients. What if an anesthesia provider administers his or her standard recipe for anesthesia without noticing that their current patient only weighs 88 pounds? Standard doses for a 150-pound person will be excessive in an 88-pound patient.
  7. Patients with decreased function of one or more of the major organ systems, that is the heart, lungs, liver, or kidney. Depending on the medication, one or more of these organ systems are required to clear the drug from the body. A patient with heart failure or decreased cardiac output will not be able to pump the drug efficiently throughout the body to the lungs, liver, or kidneys to clear the drug. A patient with decreased lung function/ventilation will not be able to exhale vapor anesthetics promptly. A patient with decreased liver function will not be able to clear certain drugs like narcotics from the body promptly. A patient with decreased kidney function will not be able to clear paralyzing drugs such as the muscle relaxant rocuronium from the body promptly.
  8. Patients with an abnormal brain. For example, patients with dementia, delirium, congenital developmental delay, or any organic brain syndrome may experience increased post-operative sedation due to exaggerated effects of the anesthetic medications on their brains.

Medical circumstances that contribute to prolonged patient awakening after anesthesia:

  1. The longer the surgery and anesthetic duration, the longer the wake up time. This is because the longer exposure to anesthetic drugs requires a longer time to exhale the vapor drugs or to clear and metabolize the intravenous drugs.
  2. The more complex the surgery, the longer the wake up time. Certain surgeries, for example a liver transplant, are so complex that an anesthesiologist often plans to keep the patient asleep in the intensive care unit after the surgery until the first post-operative day.
  3. An inexperienced anesthetist may resort to a standard recipe for every patient, and administer a more heavy-handed concoction of anesthetic drugs than are necessary for patients in our first list above.
  4. Painful surgery. Any surgery which hurts a great deal will require increased pain-relieving medications in the Post Anesthesia Recovery Room. Pain-relieving medications include narcotics such as morphine or fentanyl, which are sedating and sometimes nauseating. The less of these medicines you require, the more alert you’ll feel. Local anesthetic injections by the surgeon or a regional anesthesia nerve block by the anesthesiologist can decrease your need for narcotics, decrease post-operative pain, and decrease your risk of prolonged sedation after surgery.

You have little control over the drugs you’ll be given during surgery, but please inform and remind your anesthesiologist regarding any characteristics from the first list above. An honest discussion of your previous bad anesthetic experience(s), together with obtaining a copy of a previous anesthetic record(s), may grant you some control regarding how sedated you feel after future anesthetic experiences.

YOU are your own best advocate. Don’t be afraid to inform your anesthesiologist.

THE ANESTHESIA CONSULTANT

5) BOB DYLAN DRIVE

In Northern Minnesota, a “Ranger” is an inhabitant of the mining towns along the Mesabi, Vermillion, and Cuyuna Iron Ranges. Unlike a mountain range, a Minnesota iron range has no elevated topography, no grand vistas and no snow-capped peaks. An iron range is a geological phenomenon, named for the deposits of rich iron-laden minerals just beneath the earth’s surface. Rangers take great pride in their iron mines. They’ll tell you the American ships, tanks, and planes which won World Wars I and II were constructed from steel that originated in these Minnesota mines. No tunnels are required to mine Minnesota ore—a mere scraping of the top layer of trees and topsoil is all that’s needed to expose the largest deposits of iron-containing rock in the United States.

Johnny and I passed the open pit of the Pillsbury Mine, five miles outside of Hibbing. Deep in the concavity of mines like this one, electric shovels the size of small office buildings excavated the iron-containing taconite rock, while the largest dump trucks on Earth carried 240-ton loads of rock to the mining factories on the edges of pit.

Johnny pointed to a solitary billboard standing in the woods on the left side of the highway, and said, “Whoa, check that out.” The billboard depicted a giant fetus in utero. The caption read, Hello world. My heart was beating 18 days after conception.

“Hmm. Disturbing,” Johnny said. “What’s the point of that?”

“Some folks up here don’t believe in abortion. They believe life begins in the womb. I guess they pay for billboards to try to sway people to their way of thinking.”

Two more curves up the road, the town of Hibbing spread out before us. A row of boxy stucco homes stood shoulder to shoulder, their canted roofs covered with fresh snow. A silver water tower bearing the stenciled name HIBBING crested a hilltop behind them. Our journey was at an end.

Bob Dylan once wrote, “Hibbing’s a good ol’ town… I ran away from it when I was 10, 12, 13, 15, 15 ½, 17 an’ 18. I been caught an’ brought back all but once.” I followed a similar path. I blew out of this town years ago, and clawed my way to a better life in California. I vowed never to return. That was before I had a son, a son who needed Hibbing.

I turned onto Howard Street, the main thoroughfare, and drove along the downtown strip of commercial buildings. Neon lights flashed the names of two banks, three restaurants, three taverns, and a liquor store. Six inches of new-fallen snow covered the surface of the two-laned street. Our tires made a scrunching sound as we drove. Mounds of ice and snow lined the perimeter of the road like levees isolating the street from the storefronts.

The vista was familiar, and it saddened me. Hibbing was unchanged from the Januarys of my youth. A woman dressed in a bulky goose-down parka crossed Howard Street in front of us, her scarf trailing in the wind behind her. I slowed to let her pass. She tested the snow-covered surface with exacting steps. Johnny followed the parka-clad woman’s progress in wordless wonder.

I drove the 12-block length of Howard Street and made a left turn onto 1st Avenue, the second of Hibbing’s two main business routes. Similar to Howard Street, 1st Avenue was home to three gas stations, four more bars, and two liquor stores.

“What do you think?” I said.

“There’s not much here,” Johnny said. “It looks like a ghost town. Black and white. Dark buildings and white snow. Lots of bars and liquor stores.”

“Alcohol is a tonic against the tedium. It’s a long winter up here.”

“Iron miners drink a lot?”

“As long as there have been mining towns, there have been mining towns with taverns. But Hibbing is different. There are a lot of educated people here. Remember, this is the biggest urban area between Duluth and Winnipeg.”

Johnny laughed. “That’s not saying much, Daddy-O.”

I turned off 1st Avenue and drove through six blocks of humble residential neighborhoods until I reached 7th Avenue, a narrow tunnel between rows of stark leafless trees. Stocky two-story homes lined up behind the trees like chess pieces behind pawns. Windows were miniscule. Walls were thick. The buildings were efficient barricades for holding in heat against brutal conditions. Hibbing houses weren’t built for style; they were built to protect people from bitter cold.

After five or six blocks, the 7th Avenue street signs changed, and read Bob Dylan Drive. I parked the car when we reached the corner of 24th Street and Bob Dylan Drive. The corner house was a two-story grey cube lacking a single gable. Foot-long icicles hung from the roofline. No sign or placard designated the structure as a famous building.

“Why are we stopped here?” Johnny said.

“This was Bob Dylan’s house.”

“This was where he was born?”

“No. He was born in Duluth, 75 miles south of here. His parents moved to this house when Dylan was a boy. His real name was Robert Zimmerman, and this was his home back in 1959 when he graduated from Hibbing High School.”

“So it’s not a museum or anything.” Johnny craned his neck to take in the particulars of the scene.

“No. It’s someone’s residence. I don’t know who lives here now, but it’s just a regular house.”

As I spoke, a man came out of the front door. He tightened the hood of his parka against the wind and aimed a shovel at the snow on the walkway. After his second shovelful, he stopped and looked up at us in our bashed-in BMW. A $120,000 German sports car with a smashed-in front end and California license plates couldn’t be commonplace in Hibbing in January. On the other hand, I suspect an out-of-town vehicle perusing the old Zimmerman home was not unusual. Muslims made pilgrimages to Mecca. Dylan fans made pilgrimages to Hibbing.

The shoveler wore his hood pulled down over his eyebrows and a brown scarf wrapped snug over his mouth. Only his eyes were exposed to the frigid air. He continued to stare at Johnny and me.

Behind my windshield, I felt like a goldfish inside an aquarium. To ease the awkwardness of the moment, I waved at the man. The resident of 2425 Bob Dylan Drive only exhaled steam into the frigid Minnesota air. He did not wave back.

“Friendly guy,” Johnny said.

“Cut him some slack. I’ll bet every day some dude from New York, Pennsylvania, Illinois, England or Italy knocks on this guy’s door and asks him if they can take a tour of the house. It must get old.”

“Let’s get out of here,” Johnny said.

I put the car in gear and drove thirty seconds down the road to the intersection of Bob Dylan Drive and 21st Street. To our right, an imposing three-story red brick fortress sprawled over four square blocks. It was easily the largest building in town.

Johnny craned his neck up at the structure, and said, “What’s this?”

“This is your new school.”

“It looks like a castle. How can they have such a monster school in such a little town?”

“A hundred years ago the town of Hibbing was located two miles north of here. When the mining companies discovered the richest supply of iron ore in the United States in the soil below the existing town, they cut a deal. The mining companies agreed to move the entire village and build Hibbing this wonderful high school in the new location as a reward for being relocated. C’mon, let’s go take a look.”

We walked up the front steps of the high school. I touched the brass railing with my bare hand, just like I had when I was 17 years old. At that moment, I was proud of my roots and proud of my alma mater. The front door was unlocked, and we stepped inside. The entryway was adorned with a tiled mosaic floor, a majestic marble staircase, and original oil paintings and murals on the walls depicting the history of the Iron Range.

“It looks like a museum,” Johnny said.

“See that plaque? This building is on the National Register of Historic Places. Wait until you see the auditorium.”

We walked to the end of the main hallway and passed through a set of double doors into the auditorium, an Art Deco wonder adorned by cut-glass chandeliers built in Czechoslovakia, and modeled after the ornate Capitol Theater in New York City. With a capacity of 1,800, the auditorium could seat every student in the school at once.

“This is where I received my high school diploma. And this is where Bob Dylan first performed and sang in public. They say he banged on the piano like a Little Richard clone.”

Johnny said nothing. He was biting the nails of his right hand, and he looked nervous.

“You OK?” I said.

“I don’t know. Now that I see this place, I’m getting worried. What if it doesn’t work out for me here? I mean, wherever I go, I’m still Johnny Antone. What if I’m in the middle of the pack here, just like I was in Palo Alto? What if we moved here for nothing?”

“You’ve got what it takes, Johnny. You’ll do great here. Let’s go. I’ve got something else to show you.” I led him out the front entrance of the school, and pointed across the street to a white colonial mansion on the corner of Bob Dylan Drive and 21st Street. It was twice the size of any house we’d seen in town. The front lawn was an expansive half-acre of drifted snow.

“That’s Uncle Dom’s house,” I said.

“Nice.”

“It’s one of the most impressive homes in town. When I was a schoolboy, doctors were the wealthiest people, and Dr. Dominic Scipioni was the top surgeon in Hibbing.”

We crossed the street together. Dom’s front walk was covered by a foot of crusted snow, unbroken by a single footprint. Johnny tip-toed up the path, his Nike Air Jordans sinking in and filling with snow on every step. “Dom isn’t doing a great job of keeping the snow off his walk,” he said.

“He doesn’t live here anymore, that’s why we got the place. Dom has homes in Arizona and Montana. He keeps this family house for the nostalgia of the old homestead.”

“What’s the deal with this Uncle Dom, anyway?” Johnny said. “Is he your uncle, or is he my uncle?”

“He’s nobody’s uncle. Dom’s not related to any of us, but he’s always treated me like family. Dr. Dom was my role model and mentor ever since I was a teenager.”

I bent over and peeled back the corner of the welcome mat. A shiny steel key lay underneath. “This is a sweet deal for us. We get one of the best houses in town, two blocks from the hospital and across the street from the high school, no questions asked. It’ll be our Minnesota man-cave.”

Johnny followed me into the house. The interior was meat-locker cold. We could see the water vapor of our breath. A lifelong ectomorph, I loathed hypothermia. I turned the thermostat up to 72 degrees and switched on the lights in the living room. “I recommend you proceed at once to the den in the basement. Dom has three big screen televisions, side by side by side. You can watch the NBA, the NHL, and the PGA Tour at the same time, by the mere effort of swiveling your neck a few degrees. And you want to know the best thing about Dom’s house?”

“What’s that?”

“There’s no one here to yell at you.”

“I’m with you there, Dad.” Johnny descended the stairs into the basement.

I toured the living room. Dom’s house lacked the towering ceilings of our glassed-in California home. The space felt claustrophobic with its tiny square windows, dark paneled walls, and smoke-stained brown-bricked fireplace. I knew every knot-hole in this room from my previous lifetime here, when Dom’s family was my family. Once upon a time, this room represented the height of luxury to me.

I walked over to the framed black-and-white photograph I knew would be standing on the fireplace mantle. The photo portrayed a young man and a young woman dressed in formal attire. The dark-haired girl wore a square-necked white dress, and held a broad bouquet of flowers. Her lips were closed, and she had a solemn, far-away look in her eyes. The man wore a tuxedo and a goofy smile that was incongruous with the woman’s apparent gloom.

A flood of grief overcame me. I’d traveled all day, and this picture was the tortured endpoint to my journey. It was Dom’s house, and Dom could decorate the place as he pleased. Some people preferred to put their memories on their fireplace mantles. Some memories were better left hidden.

The boy in the picture was Nico Antone. And the girl? She was from another lifetime. I’d shoveled dirt over this unsmiling girl years ago. She was dead, and I needed her to stay dead.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

4) HIGHWAY 61 VISITED

I drove the black bullet of my BMW up Minnesota Highway 61, one hour north of Duluth and two hours short of the Canadian border. Johnny and I flew in from San Francisco to the Twin Cities that morning, and picked up the car from an interstate driving service in Minneapolis.

Our send-off in California was bitter. Alexandra dropped us off at the curb at San Francisco International Airport. She gave Johnny a big hug and said, “I love you, John-John. Call me every night.”

“Love you too, Mom,” he said. I watched their exchange with intrigue. Although he was eager to move thousands of miles away from her, Johnny still loved his mother. What can you say? She was the best mom he’d ever had.

As for me, I wasn’t going to profess any love this morning. Alexandra faced me, her eyes vacant and cold. “Are you going to be OK without us?” I said.

“I’ll be better than OK without you,” she said, her voice dripping with its customary arrogance. “If I’m lucky, you’ll never come back.” She grabbed the door handle of her Aston Martin, jutted her chin toward the sky and said, “Go.”

That’s the way it ended. I watched her drive off, and I was jolted by an unexpected surge of glee. I felt an unfamiliar sense of freedom, like a captive hawk unhooded and released from its tether. I had no idea when I would see her again, and I wasn’t in a hurry to find out.

Ten hours later, Johnny and I were driving north on a spectacular Minnesota winter day, with the blue expanse of Lake Superior sprawling ocean-like on our right and the setting sun disappearing behind the infinite expanse of pines on our left. I detoured up Highway 61 for the novelty of the famous road, so my son could witness the world’s largest freshwater lake. The scenery was world class, but for me the highlight was spending time with Johnny uninterrupted by the distractions of a television, an Xbox, or cell phone calls. Exiled from California, Johnny had no friends except me, and I liked it that way.

He slumped in the passenger seat and stared out the side window. Despite the winter temperatures, he’d rolled down his window and the icy breeze from Highway 61 fluttered through his hair. I was in control of the music. For this occasion, it had to be Bob Dylan. I cued up “Highway 61 Revisited,” and blasted the title song though the speakers. I belted out the lyrics in a nasal twang: “Well Abe says, ‘Where do you want this killin’ done,’ God says, ‘Out on Highway 61.’” My “61” came out as a screeching “sexty-waawn,” mimicking Dylan to the best of my ability.

“Bob Dylan wrote that song about this highway?” Johnny said.

“He did.”

“It’s a pretty creepy lyric. And you’re screaming it out like it’s an anthem. He’s singing about killing a son?”

“It’s from the Old Testament. God told Abraham to sacrifice his only son.”

“So? Did he kill his son?”

“No. He was prepared to do it, to obey God, but at the last minute God sent an angel to stop him. Instead of killing his son, Abraham sacrificed a ram.”

Johnny shook his head. “What kind of song is that? Sorry, Dad. I can’t get into the Dylan thing. It’s so hard to listen to the guy’s voice. That screeching is pretty awful.”

“Bob Dylan is one of the most imitated vocalists of the last hundred years. He gave every singer with a less-than-perfect voice a blueprint of how to sneer and twist off syllables.”

“He’s all mumbles to me.”

“Try to get past the sound of his voice, and listen to the words. Dylan was the first songwriter to turn poetry into popular music.”

“Who cares about poetry?”

“What is rap and hip-hop music but poetry? What do Jay Z or Kanye West do but chant some simple rhymes over a drum beat?”

Johnny looked unconvinced.

“Bob Dylan changed music forever. Before Dylan, the top singers were crooners like Frank Sinatra and Elvis Presley, guys with silky voices who performed songs written by unknown people. Then along came Dylan, coughing out “Blowin’ in the Wind” with a voice like sandpaper on wood. He jammed his songs into your ears with that raspy nasal twang, and crossed you up with changes in inflection no one ever heard before.”

“Why would anyone ever listen to that?”

“Great songs. ‘The Times They Are A-Changin’,’ ‘Mr. Tambourine Man,’ ‘Like a Rolling Stone.’ Songs that influenced every writer that followed after him.”

“It doesn’t make sense to me. How can a guy who changed the world come out of all this?” Johnny said, waving his hands at the endless forests. “From up here in the sticks?”

“God only knows where genius is born, but education had something to do with it. Hibbing High School. The same classrooms and hallways you’ll be in tomorrow.”

I spun the steering wheel to the left as we departed Highway 61 and veered west toward the heart of the Superior National Forest. Lake County Highway 15 was a curving two-lane highway that slalomed over gentle hills and carved through wilderness untouched by 21st-Century development. It connected the two metropolises of Silver Bay and Hoyt Lakes, each with a population of about 2,000. The road was smooth and the setting was desolate. We hadn’t seen another car in ten minutes. I compressed the accelerator pedal and watched the speedometer climb. “Hang on, son. We’re going for triple digits.”

When our speed hit 100 miles per hour, I looked over at Johnny. There was no trace of fear—he was loving it.

A sudden blaze of brown fur streaked across the road as the deer jumped out of the forest 100 yards in front of our car. “Shit!” I yelled, and stomped on the brakes so hard I thought my foot would break through the floorboard. Our car fishtailed counterclockwise. The rear wheels made a skid into the dirty snow on the side of the road, and our front fender slammed into the deer’s flank. I heard the crunch of crumbling steel, and saw the deer’s white tail slide up the windshield and over the top of the car. The airbags deployed, and twin balloons of white fabric blotted out the sun. The rear of the car wracked into something solid and stopped with a resounding thump.

I reached down and turned off the ignition. My hands were shaking. We’d hit the deer broadside at 100 mph. Highway 15 was now graced with one dead deer, one smashed-up BMW, and two happy-to-be-alive Antones. I took census of my four limbs and my vital functions. I didn’t seem to be injured. I feared for Johnny. I elbowed my air bag aside, and looked over at the passenger seat. There was movement behind Johnny’s air bag. I pushed the fabric aside, and saw my son crouched forward with his head between his knees.

“Are you all right?” I said.

Johnny was hyperventilating—a violent wind entered and exited his gaping mouth. Blood dripped from the right side of his chin. “Are you nuts, Dad?” he screamed. “You almost killed me. That was the scariest thing I’ve ever seen.”

I was reeling. What kind of father was I? I’d almost offed us both. “I’m sorry,” I said. “I didn’t think…”

You didn’t think? Do you ever think? Oh, what the hell am I doing up here?” Johnny buried his face in his hands and wailed, “Everybody I know is in California. My mother is thousands of miles away. I’m up here in the woods with you, stuck in a ditch in outer Mongolia. We’re going to freeze to death and die right here. I should never have left home.”

I didn’t know what to say. I started to reach out toward my son to comfort him, but Johnny grew more agitated, turned away, and wrestled with the airbag until he found the door latch. He pushed the door ajar, and burst out into the sub-freezing air outside.

I opened my own door and twisted my way out of the car. The right front quarter of the vehicle was buckled like an accordion. The deer lay mangled on the roadside at the rear of the car, its glassy eyes staring skyward into the void. Blood seeped from its ears, nose, and mouth. Its thorax was buckled, concave and deformed.

What a waste.

Behind me, Johnny said. “Dead deer. Totaled car. Stranded in the middle of nowhere. Great job, Dad.”

“It all happened so fast…”

“No. You were driving like a maniac, and now we’re stuck. We’re so stuck. There’s no people in these woods but lumberjacks. Lumberjacks who would be hunting this deer if you hadn’t killed it.” Johnny shook his head. He stuck out his jaw, square and resolute. “I’m done. I changed my mind. I want to go home.”

I’d heard enough. “No. We’re going to Hibbing,” I barked. “It’s what you and I decided to do. Together, that’s what you and I decided.”

“I’m un-deciding.”

“It’s too late for that. I’m pulling rank on you. We’re in Minnesota, and we’re staying in Minnesota.” I walked back to the driver’s door, unsheathed a small Swiss Army knife from my key chain, stabbed the point of the blade into the airbag, and slashed a 10-inch gouge in the material. I squeezed the remainder of the air out, compressed the bag into a dense lump the size of a basketball, and stuffed it back into its housing inside the steering wheel. I repeated the same treatment on the passenger airbag, and pushed the deflated fabric back into the dashboard.

“Get in,” I commanded.

“You don’t understand, Dad. What’s the point of getting into this wreck of a car, marooned ass-end first in a snow bank?”

I ignored his sky-is-falling attitude, and pushed the ignition button. The engine sprang to life. I floored the accelerator pedal, and listened to the roar of the motor echo off the virgin pines around us.

“Get in,” I repeated.

Johnny looked both ways on the deserted highway, and his shoulders slumped. He climbed into the passenger seat, with a look of hopeless resignation etched on his face. We were miles from the nearest town, and the deformed car was our only hope to limp out of the wilderness. I shifted the transmission into Drive and wondered if the right front tire would move within the mangled fender. With a lurch, the BMW rolled forward out of the snow bank. Lucky us. I whistled through my teeth and turned the automobile back onto Highway 15 for the last leg of our trip toward Hibbing.

I vowed that the next time I saw God, I’d run a little slower. Abraham sacrificed a ram instead of killing his son.

I settled for a deer.

How common are cardiac arrests during surgery? Uncommon, but the incidence is not zero and the outcome is usually dire.

In 2004 the Japanese Society of Anesthesiologists reported 2,443 cardiac arrests (6.34 per 10,000 anesthetics) and 2,638 deaths (6.85 per 10,000 anesthetics) among 3,855,384 anesthetics. The majority of deaths were due to preoperative health complications (64.7%) and surgical problems (23.9%). The main preoperative problem leading to death was hemorrhagic shock, and the main surgical problem leading to death was excessive surgical bleeding. The incidence of cardiac arrest totally attributable to anesthesia mismanagement was low (0.47 per 10,000 anesthetics), and anesthesia mismanagement was responsible for only 1.5% of deaths. (1)

The American College of Surgeons National Surgical Quality Improvement database from 2005 to 2007 documented the incidence of intraoperative cardiac arrest in non-cardiac surgery as 7.22 per 10,000 cases. Intraoperative blood loss, represented by the amount of blood transfused, was the most important risk factor. Patients receiving over 10 units of blood had greater than 10 times the risk of those receiving 1-3 units of blood. Two other significant risk factors were emergency surgery and the patient’s preoperative health as assessed by the American Society of Anesthesiologists (ASA) physical status ranking. Of the 262 patients with intraoperative cardiac arrests, 44% died within 24 hours and 62% died within 30 days. (2)

From 2010 to 2013 the National Anesthesia Clinical Outcomes Registry reported the risk of intraoperative cardiac arrest as 5.6 per 10,000 cases. Fifty-eight percent of these patients died. The incidence of cardiac arrest increased with age and ASA physical status ranking, with the majority occurring in patients with an ASA physical status of 3-5. (3)

Physicians from a Thai teaching hospital reviewed 44,339 emergency surgery patients from 2003 to 2011, and found the incidence of perioperative cardiac arrest in emergency surgery was 163 per 10,000 cases. Risk factors were age 2 years or younger, an ASA physical status of 3-4, risky anatomic sites of surgery (upper abdomen, intracranial, intrathoracic, cardiac, or major vascular), cardiac or respiratory comorbidities, and shock prior to anesthesia. (4)

A Brazilian study documented a higher incidence of perioperative cardiac arrest in children than in adults. From 1996 to 2004, 15,253 anesthetics were performed in children. There were 35 cardiac arrests (22.9 per 10,000) and 15 deaths (9.8 per 10,000). Risk factors for cardiac arrest were children under one year of age, emergency surgery, ASA physical status 3-5, and general anesthesia. There were 11 cardiac arrests related to anesthesia care. Seventy-one per cent of these were caused by airway management/respiratory events, and 28% were caused by medication-related events. There were zero deaths attributed to anesthesia. (5).

What does all this mean?

If you’re an anesthesia provider, know that that the risk of cardiac arrest during surgery and anesthesia is low. The average reported incidence is in the ballpark of 6 to 7 per 10,000 cases, higher in children (22.9 per 10,000), and highest in emergency surgeries (163 per 10,000).

A busy anesthesiologist doing his or her own cases performs 1000 anesthetics per year. A predicted experience would be one cardiac arrest every 6-7 years, or 4-5 cardiac arrests in a 30-year career. A physician anesthesiologist supervising four CRNAs in four operating rooms could do four times as many cases per year, so a predicted incidence would be 16-20 cardiac arrests in a 30-year career.
Anesthesiologists should be prepared to promptly manage cardiac arrests in the patients at highest risk, which include: those with extensive bleeding and transfusion requirements; patients in shock; emergency surgeries; particularly emergency surgeries involving the upper abdomen, craniotomies, cardiac, intrathoracic, and major vascular vessels; patients with preoperative physical status limitations (ASA physical status 3-5); and children under one year of age.

In 30+ years of administering approximately 25,000 anesthetics I’ve seen cardiac arrests in three cases, for a personal anecdotal incidence of 1.2 per 10,000. All were in the high-risk categories above. One patient was in hemorrhagic shock prior to surgery because of an acute bleed from a ruptured aortic aneurysm, one patient was undergoing aortic artery bypass surgery, and one patient was a sick end-stage renal disease dialysis patient undergoing vascular surgery.

If you’re a patient, realize that your risk of having a cardiac arrest under anesthesia is low. If you have any of the risk factors described above, your risks are higher. Trust that the surgeon and physician anesthesiologist who take care of you will be well prepared, aware of this data, and will take excellent care of you while you are asleep.

In the future, physician anesthesiologists will have an abundance of “Big Data” on clinical issues such as this one. The ASA and its affiliate, the Anesthesia Quality Institute (AQI), are compiling the National Anesthesia Clinical Outcomes Registry (NACOR), which has been designated as a Qualified Clinical Data Registry (QCDR) by the Centers for Medicare & Medicaid Services for Physician Quality Reporting System (PQRS).

Can we lower the incidence of perioperative cardiac arrest? Perhaps, as we gain more understanding of risk factors. But as the Baby Boomer population in the United States ages, there will be more old patients, more patients with multiple medical problems, and more emergency surgeries on older, sicker patients.
Anesthesiologists will continue to be challenged.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

3) QUEEN ALEXANDRA APPROXIMATELY

I drove my black BMW M6 convertible up the semicircular driveway to our Palo Alto home after work, and parked behind my wife’s silver Aston Martin One-77. Together, the value of the two cars approximated the gross national products of some third world nations. Our home was a 7,000-square-foot Tuscan villa built on a hilltop west of the Stanford University campus. The Antone estate encompassed three acres of tranquility, and towered above an urban area of seven million Californians, most of whom were mired in less-than-tranquil rush hour traffic at that very moment.

Our living room featured thirty-foot-high ceiling-to-floor windows overlooking San Francisco Bay. The décor included opulent white Baker couches no one ever sat on and a Steinway grand piano no one ever played. I sped through the formal room at flank speed. I couldn’t remember ever spending more than five minutes hanging out in this museum piece of showroom design.

I carried a large bag of Chinese take-out food from Chef Chu’s, and set it down on the stainless steel countertop of our spotless, never-used kitchen. I made a beeline for the refrigerator, popped the top off a Corona, and chugged half the bottle. I was still vibrating from my day in the operating room. I looked out the French doors toward the back patio.

Alexandra was lying on a lounge chair and sipping a tall drink through a straw. A broad-brimmed Panama hat graced her swirling mane of black hair. She wore a white one-piece swimming suit. It was an unseasonably warm day for January, and my wife never missed an opportunity to bronze her lanky limbs.

I walked up behind Alexandra, wrapped my arms around her neck, and kissed her left cheek. She held a cell phone against her right ear, and she pushed me away while she continued her conversation. I frowned and said nothing. Was it so hard for Alexandra to pretend she loved me? I sank into a second chaise lounge beside her, closed my eyes and listened.

“That property is overpriced at $6.5 million,” she said. “I know we can get it for 6.2. Put in the bid tonight and tell the seller they need to decide by tomorrow morning or the deal’s off. Got it? Call me back when they cave. Ciao.”

Alexandra set her phone down and lit a Marlboro Light 100. She inhaled with a violent effort, exhaled the smoke through her nostrils, dragon-like, and turned toward me. She wore broad Ray-Ban sunglasses. I couldn’t tell if she was looking at me or if she was looking out over San Francisco Bay, a vista Alexandra may well have considered far more interesting.

“How are you?” she said.

“I had a busy day. Today I was in the neuro room…”

Her phone rang again, and she waved me off while she took the call. My heart sank anew. She listened for an extended time and then she said, “I’ll be there at 5. No problem. Thanks.” She hung up and thrust her fist into the air. “Got a whale on the line,” she said. “There’s a couple from Taiwan who want to see the Jorgensen house tonight. Their agent drove them by the property this morning. They are very, very interested, and very, very wealthy. It’s an all-cash deal. A blank check.” She took a second long drag on her cigarette, and leaned toward me. At this angle, I could see my own reflection dwarfed in the lenses of her sunglasses. “This is big, Nico.”

“How much is the Jorgensen house listed for?”

“Just under 8 mill. That’s a quarter of a million dollar commission for yours truly.”

Her monomaniacal pursuit of money baffled me. Alexandra Regina Antone was one of America’s top real estate agents. Because of her explosive earning power, we lived in one of the nation’s most expensive residential neighborhoods, a zip code where Silicon Valley’s multimillionaire CEO’s and venture capitalists lorded in their castles. The residential properties Alexandra bought and sold for her clients were in the $3 million to $10 million range, and she earned a 3% commission on each sale. She sold one or two houses each month, and her income for the past year topped $9 million.

Alexandra’s salary dwarfed mine. None of my medical peers lived in this kind of luxury. To Alexandra, another $240,000 commission was headline news. It wasn’t about the cash—this was about the glory of Alexandra and her talent. It was about the Queen of Palo Alto rising higher and higher on the pedestal she’d erected for herself.

“So, you were telling me about your day,” Alexandra said, as she stretched her arms toward the sky and stifled a yawn.

“I did a craniotomy with Judith Chang. One case. It took all day.”

She took a final drag on her Marlboro, shivered in disgust, and said, “Judith Chang is such a stiff. Always bragging about her robotic daughters. I don’t know how you can do that job, locked in a windowless room with her hour after hour.” Alexandra had zero interest in listening to medical stories. She changed the topic at once. “Did you hear about Johnny’s report card?”

“I did. He’s pretty upset. Johnny wishes his grades were better. I wish his grades were better. He said you yelled at him.”

“Johnny’s a slacker. God knows I tried to light a fire under him years ago, but you taught him how to watch ESPN instead of pushing academics.”

“He said you called him a lazy shit.”

“I did. He is a lazy shit.”

“He’s your son, for God’s sakes. Johnny loves you and looks up to you. How do you think he feels when his mother says that?”

“I don’t give a fuck how he feels. Johnny needs to hear it, and he needs to change. Clue in! You don’t seem to get it, either. You think he’s fine just the way he is. Well he isn’t, Nico. Johnny’s a spoiled brat, living in luxury on top of this hill. He has no incentive to work hard. He thinks he can live off my money forever.”

Alexandra was dogmatic about the pathway to success. She was an unabashed academic snob—a graduate of Dartmouth College and Harvard Business School—and she’d have tattooed her Ivy League diplomas across her cleavage if she hadn’t been too vain to disfigure her silicone orbs. I wasn’t going to fight with her—I never won.

I shifted gears. “Dr. Chang had an interesting take on Johnny’s grades. She said Johnny could get into any college he wanted to if we lived in South Dakota.” I explained how Dr. Chang’s nephew from Sioux Falls was accepted to Princeton.

Alexandra removed her hat, shook out her hair, and took off her sunglasses to reveal flashing brown eyes. “For a change, Judith Chang is right. Johnny’s chances for success are slim on his current path. He has no chance at the Ivy League coming out of Palo Alto with his B average.” She chewed on the earpiece of her Ray-Bans as she contemplated. “Why don’t we send him to Minnesota to live with Dominic?”

“You’re kidding,” I said. My Uncle Dominic had a home near the Canadian border, in Hibbing, Minnesota, where I graduated from high school. Hibbing was a great place if you wanted to hunt partridge or ice fish for walleye pike, but the tiny village was a subarctic outpost light-years removed from the opulence Johnny grew up with in California.

“I’m not kidding. Johnny needs a gimmick for college admissions, and he has none. Hibbing could be his ticket.”

“He can’t just move up there with Dominic. Johnny’s 17 years old. And Dominic moved to Arizona. His house is empty.”

“Then take a year off. Go up there with him. Get your ass out of that windowless tomb of an operating room and take your son back to your childhood home.”
I frowned. “What about you?”

“Are you kidding? I’m not going anywhere. My friends are here, my job is here. But you go right ahead, Nico.”

Now it was my turn to stare off at the blue expanse of San Francisco Bay. Move back to the Iron Range of Northern Minnesota, to the land of rusted-out Fords and beer-swilling Vikings fans? What had my marriage come to? Before Johnny was born, Alexandra and I used to sit in these same chairs and drink margaritas together. Naked dips in this same pool led to nights of laughter and hot sex. Our current sex life had declined to hall sex, when I murmured “fuck you” under my breath after Alexandra walked past me in the hallway on her way to the second bedroom where she slept alone.

Alexandra was unrelenting. “Don’t give Johnny an option. Tell him you’re taking him to Minnesota to turn his life around, get some A’s, and graduate number one in his class from Hibbing High School. Call Dominic tonight and make the arrangements. It’ll be the best decision you’ve ever made. Trust me.”

Trust me. Alexandra could sell bikinis to Eskimos. “You’re OK with your husband and son moving 2,000 miles away?” I said.

She wrapped her arms around herself in an absurd parody of self-love and said, “Of course I’ll miss you.” Then she laid back onto the chaise lounge, the top third of her breasts busting out of her swimsuit top. She knit her hands behind her head, pushed her cleavage out into the January sunshine, and grinned in silence.

I watched the spectacle of her arching self-absorption and winced. Move 2,000 miles away? I was 2,000 miles away from this woman already.

“Hey guys,” came a voice from behind us. Johnny was home from school. He walked onto the patio and stood between us. My mood improved at once. Our son was tall and muscular with perfect skin, dark wavy hair, and striking blue eyes. He wore his usual uniform of gym shorts and an oversized T-shirt. My love for Johnny was unlike any emotion I’d ever felt. Romantic love for a woman was a wonderful abyss—the subject matter of a million songs, books, movies, and television shows. I’d watched romantic love drift off into the ozone as years passed, but with my son I was in love forever. If Alexandra and I ever divorced, I’d carry on. If my son ever shut me out, I’d need electroshock therapy.

Johnny wasn’t smiling. His shoulders drooped, his chin scraped his chest, and his gaze was locked onto the slate tiles under his well-worn Nike athletic shoes.

“How’s the Boy with the B’s doing?” Alexandra said.

Johnny regarded her through hooded eyes—James Dean with a cause. His upper lip curled skyward in a look of contempt. He was already smoldering from a bad day, and she was throwing kerosene on his fire.

She forged on, hawking optimism now. “Dad and I have a great plan for you that should make your report card problem of no consequence.”

“Great plan?” Contempt turned to suspicion.

“Johnny, are you happy that your grades rank you in the middle of the pack at your school?” she said.

“You know I’m not,” he sneered. I didn’t have a 42-inch monitor displaying Johnny’s vital signs, but I knew my son’s blood pressure was escalating.

“Would you like to be accepted into a top college?”

“Duh. Of course, Mom.”

“What if we told you there was a way for you to graduate at the top of your class and go on to one of America’s best colleges?”

“I’d say you were smoking too much weed.”

“No weed.”

“How am I going to jump to the head of my class at Palo Alto Hills High?”

“Not Palo Alto Hills High School, Johnny. Hibbing High School.”

Johnny looked from me to his mother and back again. “You two are messed up. Hibbing? Where the hell is that?”

“Hibbing is in Northern Minnesota. It’s where your dad grew up. It could be worse. We’re not sending you off to some military school in the badlands of Utah where you don’t know anyone. Your dad will move to Minnesota with you.”

“That’s ridiculous… Dad?” he said, panic in his voice.

I opened my mouth, but Alexandra didn’t give me a chance to weigh in. “There are consequences for your lack of effort in school, Johnny,” she said. “We want you to get out of Palo Alto and compete for grades with the sons and daughters of some iron ore miners. Right, Nico?” She turned to me for affirmation.

Johnny’s jaw sagged. “Dad?” he said again.

“I’m overdue for my sabbatical at the University,” I said. “My Uncle Dominic has a house in Hibbing. With your brains, your test scores, and a lot of hard work, you could be a top student up there. Instead of being a middle-of-the-pack Palo Alto student, you could be….” At this point I decided to gamble and appeal to my son’s ego and vanity, “You could be the valedictorian.”

“Can the best students from a school like that get into a top college?”

“They can. When I was a senior at Hibbing High, two kids were accepted to Harvard. It’s got to be the best high school in the northern half of Minnesota.”

“Whoa. Harvard?”

“Yes, Harvard.”

Johnny looked over at his mother. She smirked, as if she’d single-handedly masterminded a strategic maneuver worthy of Machiavelli.

“I’ll have to think about this,” Johnny said.

“I’ve got to shower and get ready for my meeting,” Alexandra said. “Nico, you guys are on your own for dinner. Johnny, I’m sure you’ll love Minnesota.” She rolled off her lounge chair as Johnny covered his eyes and pressed his thumbs into his temples.

She walked away, and I admired the swagger of her slender hips and the bounce of her long tresses. I never got tired of looking at Alexandra, but it wasn’t much fun living with a woman whose best friend was her mirror.

I turned to Johnny. “Want some Chinese food?” I said.

“I’ll eat it in my room, Dad. I have a ton of homework. I’m really pissed off about everything and I don’t want to talk anymore. First I get the crappy report card, and now you guys want to ship me off to the Yukon. All you guys care about is grades. You don’t give two shits about whether I’m happy or not.”

“That’s not true.”

“It is true. Just leave me alone. I’m going to my room. This B-student has a date with Hamlet.” Johnny walked away, and I let him go. My B-student son needed more dates with the Danish prince.

I dished out a plate of Szechwan prawns and General’s Tso’s chicken, and popped the top off a second Corona. The Golden State Warriors were playing the Miami Heat at 6 p.m. A second Corona, some Schezwan prawns, and the basketball game sounded like a decent evening.

After halftime, Johnny came shuffling down the hallway. He stretched out on the couch opposite me, and opened his laptop. He was humming to himself, and his fingers were flying.

I was happy to see he’d cheered up. “Feeling better?” I said.

“Yep. The Chinese food hit the spot.”

I waited for more conversation, but none was forthcoming. The Warriors connected on an alley-oop and an outrageous dunk. Johnny didn’t look up.

“How’s Amanda?” I said, trying to stoke up a dialogue. Amanda Feld was Johnny’s girlfriend, a petite cross-country runner who gazed at Johnny like he was a Greek god. She hadn’t been over for a couple of weeks, and Johnny hadn’t brought up her name for longer than that.

“Amanda’s history,” Johnny said.

“History?”

“I broke up with her a month ago, Dad.”

“What happened?”

“Nothing happened. It didn’t work out.”

“She was cute.”

“Yep.”

I waited for more of an explanation, but none came. Amanda’s fate paralleled all the other breakups of the past year, when Johnny ended relationships with Samantha the cheerleader, Emily the debate star, and Jenna the girl across the street. Johnny seemed to attract girls by repelling them. The less interest he showed, the more the women orbited him. I was envious.

Johnny said, “The report card and class rank bullshit really wore me down today. Why should my whole future revolve around some alphabet letters on a page?”

“It doesn’t. Your life is much more than your grades.”

“Yeah, like what?”

I pointed my two forefingers at my son just like I had a thousand times in his life, and said, “You’re a great kid. Don’t ever forget it.”

“Why do you always have to say that to me, Dad?”

“Because it’s true. I want you to imprint it in your brain and never doubt it.”

“Even if I can’t get an A in one class?”

“Even if you can’t get one A.”

“I want to get A’s. All A’s. But transferring to Minnesota?” Johnny tapped the screen of his laptop and said, “I’m looking at the Weather Channel website. It’s minus five degrees and snowing in Hibbing right now.”

“Yep. That’s why I left. In the winter the sun sets at 3:30 in the afternoon.”

“That’s insane.”

“It ain’t California.”

He shook his head. “I’m going to sleep.”

“Good night, son. I love you.”

“Love you, too,” Johnny said, and then he headed off toward his room.

I welcomed the tranquility from the two beers. My eyelids grew heavy, and I faded toward unconsciousness. My cell phone rang and woke me. I didn’t recognize the number. I answered the call, and a male voice said, “Alexandra?”

“No, this is her husband’s number. Who’s calling?”

There was a click as the line went dead. The heaviness in my eyelids was gone. I found myself mistrusting my wife.

Again.

I woke in the middle of the night. I’d dozed off in my chair in front of the flickering television. A Seinfeld rerun was playing. I turned off the TV, tried my best to stay asleep, and stumbled down the hallway toward my bedroom. The door to Alexandra’s bedroom was open, and her bed was untouched. I looked at my watch. It was 2:07 a.m.

A surge of annoyance ran through me. Where the devil was she at 2 o’clock in the morning on a Thursday night? My hopes for a quick return to slumber were dashed. I was full of adrenaline, and I wasn’t going back to sleep anytime soon. I walked into her room and laid down on her bed. The familiar smell of her hair from the pillows jolted me. It had been a long time since we’d touched the same sheets together.

I heard a car door slam outside. A minute later, Alexandra stood in the bedroom doorway. She carried her high heel shoes in one hand and wore a black spaghetti strap cocktail dress. Those spectacular legs were glistening from mid-thigh on down.

She was startled to see me. “What are you doing in my room?” she said.

“Waiting up. Where were you?” My voice quivered with resentment.

“Oh, Jesus, Nico. I’m not a sixteen-year-old girl, and you’re not my dad. I went out with the girls and had a couple of drinks and some laughs. It was fun. You should try it sometime.”

“I don’t believe you.”

“Believe whatever you want. Can you get out of my room now so I can go to sleep?”

I turned on the overhead lights, and examined the illuminated spectacle of Alexandra Antone. Her arms were crossed, and she was smirking down at me. A streak of red lipstick stretched from her upper lip across her right cheek. Was she was playing kissy-face with the girls?

I lost it. “Are you playing me?” I said.

“What are you talking about?”

“Are you playing me for a fool? Who were you with?”

She turned her back on me and walked into her closet. “You are such a buzzkill,” she called out. “You always hate it when I have fun. I have a life. I’m sorry you’re jealous.”

I ran to her like a wild bull. I grabbed her by the arm and swung her around to face me.

“Are you having an affair?” I screamed.

Dull eyes stared back at me. Alexandra blinked twice, shook her head in disgust, and said, “No, I’m not. And get your hands off of me, Nico. You’re still the same small-town hick you’ve always been.”

Her defiance infuriated me further. “I’m sick of you, and I’m sick of our bogus marriage.”

She laughed at me and said, “You need to find somebody else. Someone who likes listening to your boring medical stories. Someone who wants to cook meat and potatoes for you. Someone who enjoys staying home and watching TV with you.”

“I’m married to you. I’m not finding anybody else while I’m your husband.”

“Are you my husband, Nico? Or my dependent?”

I saw flames. I picked up her six-foot-tall cast iron coat rack and rammed the shaft through the closet wall. The metal hung there, cleaving the room between us.

“Are you crazy?” Her shriek was ear-splitting.

“At least I’m not a whore.” With those words, I’d crossed the line. As of that moment, I knew I could no longer live with the woman. “If you want to stay out half the night like a tramp, don’t bother to come home at all.”

“I’m not going anywhere,” she screeched. “You’re the one who needs to move out. I paid for this damn house.”

The hardwood floor creaked behind me, and a voice bellowed, “Shut the fuck up! Both of you!” It was Johnny, standing in the doorway in his undershorts. My world stopped. Alex and I stared at our son, and no words were offered.

Alexandra spoke at last. She said, “Whatever. Can you two get out of my bedroom now?”
Johnny shook his head and disappeared into the darkness of his own room. I was so embarrassed and furious I found it hard to breathe. The two most important relationships in my life were imploding before my eyes. I left Alexandra’s room, and she shut her door behind me. I leaned against the closed door of Johnny’s bedroom and said, “I’m sorry, son. I’m sorry you had to hear that.”

“Then stop talking about it,” he said. I waited there for five minutes. He made no further sound. I walked away, back to my isolation in the master bedroom.
I lay in the dark with a pillow over my eyes and replayed what had just gone down. My life was ridiculous. My separate-evening, separate-bedroom, give-your-husband-shit-whenever-possible marriage was ridiculous. How could Johnny have a healthy adolescence under these circumstances?

I had no answers. I was angry, depressed, and reeling. I reached into the drawer of my bedside table, pulled out my bottle of Ambien, popped two, and chased them with a swallow of water from last night’s glass. I was an expert at anesthesia, even when I was the patient.

The next day I dragged myself through five routine surgeries although I was so angry it took all my will to concentrate on my craft. When I returned to my house that evening, Johnny was stretched out in my lounge chair. He was watching TV and typing into his laptop. He’d been asleep when I left for work that morning, so I hadn’t seen him since the screaming session in the hallway. Alexandra was nowhere to be seen.

“Hey, Dad,” Johnny said without looking up.

“Hello, son. Did you get some sleep after that whole episode last night?”

“I did. Mom gave me a ton of crap this morning for swearing at her and being disrespectful.” His face soured. If there was more to say, he wasn’t going there. He closed the laptop and said, “Other than that, it was a good day. I’ve been researching a lot of stuff about Hibbing on the Internet.”

He had my attention.

“That was excellent Chinese food last night, wouldn’t you agree?” he said.

“It was.”

“It’ll be our last decent Chinese food for awhile, Dad. I don’t think there’ll be any outstanding Chinese restaurants up there in Hibbing. I want to do it.”

“Do it?”

“I want to get away from Palo Alto Hills High, away from Amanda Feld, and away from Mom.
I want to go to Minnesota. Will you take me?” He held out his hand toward me. I stared at it and contemplated the implications of the gesture. Johnny was an impulsive kid, capable of making radical and irrational decisions in a heartbeat, but he’d never made a decision that impacted his life to this degree.

“You mean it?”

“I do. Can you walk away from your anesthesia job?”

“Well…” My thoughts were jumbled as I pondered the coin spinning through the air. Heads, I honored my love for my son and joined him in this adventure. Tails, I maintained my love for the warmth of California and my stable university job.

The tipping point was Alexandra. She was a toxic presence in my life. More than a marital separation, I needed an exorcism. It wasn’t a question of love. I didn’t even like her.
The coin landed on heads. I clasped Johnny’s outstretched hand and said, “Let’s do this, son. Let’s move.”

“Can’t wait, Daddy-O,” Johnny said.

“I’ll call Uncle Dominic in the morning and set things up.”

Johnny smiled and repeated again, “Can’t wait.”

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

THE ANESTHESIA CONSULTANT

2) A PHARMACIST’S SON IN SOUTH DAKOTA

Eight months earlier

My cell phone pinged with a text message from my son Johnny. The text read:

911 call me

I was administering an anesthetic to a 41-year-old woman in an operating room at Stanford University, while a neurosurgeon worked to remove a meningioma tumor from her brain. I stood near my patient’s feet in an anesthesia cockpit surrounded by two ventilator hoses, three intravenous lines, and four computer monitor screens. Ten syringes loaded with ten different drugs lay on the table before me. My job was to control my patient’s breathing, blood pressure, and level of unconsciousness, but at that moment I could only stare at my cell phone as my heart rate climbed.

                                                                       911 call me

911? My son was in trouble, and I was stuck in surgery, unable to leave. I wanted to contact Johnny as soon as possible, but my patient was asleep, paralyzed, and helpless. Her life was my responsibility. I scanned the operating room monitors and confirmed that her vital signs were perfect. I had to make a decision: should I call him now, or attend to my anesthetic and call after the surgery was over? My patient was stable, and my son was in danger. I pulled out my cell phone and dialed his number. He picked up after the first ring. “What is it, son?” I said.

“I’m screwed,” Johnny wailed. “I just got my report card for the first semester and my grades totally suck. Mom is mega-pissed. She’s going ballistic, and I’m screwed.”

My shoulders slumped. This was 911 for a 17-year-old? “How bad were the grades?”

“I got six B’s. I didn’t get one A. I just met with my counselor and he says I’m ranked #101 in my high school class. I’m so doomed. Mom is so pissed. She called me a lazy shit.”

I resisted my initial urge to scream at Johnny for scaring the hell out of me. The kid had no insight into what I did minute-to-minute in the hospital. Did he think his report card trumped my medical practice? Did he really think his report card full of B’s was an emergency?

“I’m not sure what’s worse, the grades or Mom’s screaming about the grades,” he said.

I imagined my wife having a temper tantrum about Johnny falling short of her straight-A’s standard of excellence, and I knew the answer to that question. My wife could be a total bitch. “I’m sorry Mom got mad, Johnny, but…”

“No buts, Dad. You know Mom’s idea of success is Ivy League or bust, and I’m a bust.”

“Son, four of your six classes are Advanced Placement classes, and those grades aren’t that bad.”

“Dad, almost everyone in the school takes four AP classes. Every one of my friends got better grades than me. Ray, Brent, Robby, Olivia, Jessica, Sammy, and Adrian all got straight A’s. Devon, Jackson, Pete, and Rod had all A’s and one B. Even Diego had only two B’s.”

“But you…”

Johnny cut me off. “There’s no ‘buts,’ Dad. I’m ranked in the middle of the pack in my class. I’m cooked. I’m ordinary. Forget Harvard and Princeton. I’m going to San Jose State.”

My stomach dropped. Johnny was halfway through his junior year at Palo Alto Hills High School. The competition for elite college acceptance was on my son’s mind every day, and on his mom’s mind every minute. Johnny was a bright kid, but the school stood across the street from Stanford University and was packed wall-to-wall with the sons and daughters of Stanford MBA’s, Ph.D.’s, lawyers, and doctors. Johnny’s situation wasn’t uncommon. You could be a pretty smart kid and still land somewhere in the middle of the class at P.A. Hills High.

“Everything will work out,” I said. “There are plenty of great colleges. You’ll see.”

“Lame, Dad. Don’t talk down to me. You stand there with your doctor job at Stanford and tell me that I’ll be all right. I’ll be the checkout guy at Safeway when you buy your groceries. That’s where I’m heading.”

Catastrophic thinking. Johnny Antone was holding a piece of paper in his hand—a piece of paper with some letters typed after his name—and he was translating it into an abject life of being average.

“Johnny, I can’t talk about this any more right now. My patient …”

“Whatever,” Johnny answered.

I heard a click as he hung up. I hated it when he did that. In the operating room I had authority, and respect was a given. With my family, I was a punching bag for of all sorts of verbal blows from both my kid and my wife.

I reached down and turned off my cell phone. For now, the haven of the operating room would insulate me against assaults from the outside world.

Judith Chang was the neurosurgeon that day. Dr. Chang was the finest brain surgeon in the western United States, and was arguably the most outstanding female brain surgeon on the planet. She peered into a binocular microscope hour after hour, teasing the remnants of the tumor away from the patient’s left frontal lobe. Dr. Chang always operated in silence, and her fingers moved in precise, calculated maneuvers. A 50-inch flat screen monitor on the wall of the operating room broadcast the image she saw from inside her microscope.

I paid little attention to the surgical images, which to me revealed nothing but incomprehensible blends of pink tissues. My full attention was focused on my own 42-inch monitor screen which depicted the patient’s electrocardiogram, blood pressure, and oxygen saturation, as well as the concentration of all gases moving in and out of her lungs. Everything was stable, and I was pleased.

It had been five hours since the initial skin incision. Dr. Chang pushed the microscope away and said, “We’re done. The tumor’s out.”

“A cure?” I said.

“There was no invasion of the tumor into brain tissue or bone. She’s cured.” Dr. Chang had removed a 5 X 10-centimeter piece of the patient’s skull to access the brain, and began the process of fitting the piece back into the defect in the skull—the placement not unlike finishing the last piece in a jigsaw puzzle. As Dr. Chang wired the bony plate into place, she said, “How’s your family, Nico?”

She hadn’t said a word to me in five hours, but once she was finished with the critical parts of surgery, Judith Chang had a reputation as a world-class chatterer. Some surgeons liked to listen to loud rock n’ roll “closing music” as they sewed up a patient. Some surgeons preferred to tell raunchy jokes. Judith Chang enjoyed the sound of her own voice. We hadn’t worked together for months, so we had a lot to catch up on.

“They’re good,” I said. “Johnny’s in 11th grade. He’s going to concerts, playing video games with friends, and sleeping until noon on weekends. Alexandra is working a lot, as usual. She just sold a house on your street.”

“I heard about that property,” Judith said. “You’re a lucky guy. That house sold for close to $5 million. Her commission is more than some doctors earn in a year. In my next lifetime I’ll be a big-time realtor like Alexandra. Does she give you half her income to spend?”

“In theory half that money is mine, but she invests the dough as soon as it hits her checking account.”

“Smart. Is Johnny looking at colleges yet?”

Her question had eerie relevance, because I’d been ruminating over Johnny’s phone call all morning. “That’s a sensitive point. Johnny just got his mid-year report card, and he’s freaking out.”

“How bad was it?”

“Six B’s. No A’s. He’s ranked #101 in a class of 480 students.” I spilled out the whole story while Dr. Chang twisted the wires together to affix the bony plate into the patient’s skull. I left out the “lazy shit” label from Johnny’s mom.

Dr. Chang had no immediate answer, and I interpreted her silence as tacit damning of Johnny’s fate. She opened her mouth and a flood of words began pouring out. “You know my twin daughters Meredith and Melody, who are sophomores at Stanford? They worked their butts off in high school. They were both straight-A students. Meredith captained the varsity water polo team, played saxophone in the jazz band, and started a non-profit charity foundation for an orphanage in Costa Rica. Melody was on the debate team and the varsity tennis team, and for three years she worked with Alzheimer patients at a nursing home in Palo Alto. Meredith and Melody were sweating bullets waiting to hear if Stanford would accept them, even though they were both legacies since I went to undergrad and med school here.

“The college admission game is a bitch, Nico. It’s not like when we were kids. It’s almost impossible to get into a great school without some kind of massive gimmick. It’s a fact that Harvard rejects 75% of the high school valedictorians that apply. Can you believe that?”

I could believe it. And I didn’t really care, since my only kid was at this moment freaking out because his grades qualified him for San Jose State, not the Ivy League. I didn’t care to hear any more about the Chang daughters right now, either. To listen to Judith Chang, her daughters were the second and third coming of Judith Chang, destined for world domination. I was envious of the Chang sisters’ academic successes—what parent wouldn’t be? But I didn’t want to compare them to my own son.

“What are Johnny’s test scores like?” Dr. Chang said.

Ah, a bright spot, I thought. “He’s always excelled at taking standardized tests. His SAT reading, math, and writing scores are all at the 98th percentile or better. His grade point average and class rank don’t match his test scores.”

“Does he have many extracurricular activities?”

“Johnny’s extracurricular activities consist mostly of watching TV and playing games on his laptop. At the same time,” I said, as if the combination of the two pastimes signaled a superior intellect.

Dr. Chang grew quiet again. More silent condemnation of my son’s prospects. “Listen to me,” she said. “My brother is a pharmacist in Sioux Falls, South Dakota. His son got accepted to Princeton, and let me tell you, my nephew isn’t that bright. His test scores aren’t anywhere near as high as Johnny’s. But he just happens to live in South Dakota. He just happens to be a straight-A student in a rural state. He just happens to be one of the best students in South Dakota.”

“How much do you think that matters?”

“It matters big time. The top schools want geographic variety in their student body. Stanford wants diversity. The Ivy League wants diversity. Princeton can find fifty kids from Palo Alto who meet their admission requirements. They want kids from all walks of life. They want … the son of a pharmacist from Podunk, South Dakota. If Johnny lived in South Dakota, with those test scores he’d be a shoo-in with the Ivy League admissions committees.”

Judith Chang turned her back on the operating room table, and peeled off her surgical gloves. The bony plate was back in place, and her patient’s skull was intact again. The surgical resident would conclude the task of sewing the skin closed. Dr. Chang paused for a moment, turned her palms upward, and said, “Just move to the Dakotas, Nico.”

I stroked my chin. She made it sound so easy.

ANESTHESIA FACTS FOR NON-MEDICAL PEOPLE: WHY DO I HAVE TO STOP EATING AND DRINKING AT MIDNIGHT BEFORE SURGERY?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

“Why do I have to stop eating and drinking prior to surgery?” This is a common question I hear from my patients—they’re puzzled by the connection between going to sleep and stopping eating prior to surgery.

 

It’s vital that your stomach is empty prior to elective surgery and anesthesia. Once you’re anesthetized, your cough reflex and gag reflex are abolished. These reflexes prevent food or liquids from entering your windpipe or your lungs, and are life-protecting reflexes in awake, healthy humans.

Under anesthesia these reflexes are absent. If you vomit or regurgitate stomach contents into your mouth, the material can descend into your windpipe or lungs. The complication of stomach contents entering your lungs is a dire event. The medical term for this occurrence is aspiration pneumonia. Aspiration refers to inhaling, and pneumonia refers to an inflammation of the lung tissue. In severe aspiration pneumonia, the lungs fail to exchange oxygen from the airways into the bloodstream, and brain and heart oxygen levels can drop to life-threatening lows.

The American Society of Anesthesiologists guidelines for fasting prior to elective surgery requiring general anesthesia, regional anesthesia, or conscious sedation/analgesia are as follows:

Fried or fatty foods                                                8 hours

A light meal (toast and clear liquids)                     6 hours

Non-human milk                                                    6 hours

Breast milk                                                             4 hours

Infant formula                                                         4 hours

Clear liquids                                                            2 hours

Clear liquids may be consumed up to 2 hours prior to anesthesia. Clear liquids include water, fruit juices without pulp, soda beverages, Gatorade, black coffee or clear tea. Milk and thick juices with pulp are not clear liquids.

These fasting guidelines do not apply to surgical procedures under local anesthesia, or to those with no anesthesia. You don’t have to fast for a dentist office visit, for example. The guidelines do apply for colonoscopies or upper gastrointestinal endoscopy procedures. The intravenous sedation drugs used for endoscopy procedures may sedate you to a deep enough level such that your gag and cough reflexes are absent.

In certain conditions, the stomach will be considered to be full even if the patient has not eaten or consumed fluids for eight hours. Acute pain syndromes such as appendicitis, a gall bladder attack, a broken bone, or a febrile illness are known to diminish the stomach’s emptying, and anesthesiologists treat these patients as if they had a full stomach whether they’ve fasted or not. Pregnant women and morbidly obese patients are also treated as having full stomachs for any surgery, because of delayed stomach emptying due to increased intra-abdominal pressure.

If a patient presents for emergency surgery, the anesthesiologist must proceed without waiting for the recommended fasting times. On induction of general anesthesia, the physician anesthesiologist will have a second individual (a nurse or a physician) apply downward pressure on the cricoid cartilage of the patient’s neck immediately upon loss of consciousness. The science of this is as follows: the circumferential ring of the cricoid cartilage encircles the windpipe.

Pushing downward on this ring compresses the esophagus below, to prevent passive regurgitation or vomiting of stomach contents. This pressing-down maneuver is called “giving cricoid pressure” or “the Sellick Maneuver,” named after Dr. Brian Arthur Sellick, the anesthesiologist who first described the maneuver in 1961. Inducing anesthesia using the Sellick maneuver is referred to as a Rapid Sequence Induction (RSI) of general anesthesia. In a RSI the anesthesiologist administers into the patient’s intravenous line: 1) a hypnotic drug such as propofol, followed by 2) a rapid paralyzing drug such as succinylcholine. The endotracheal breathing tube can then be placed in the windpipe within about 30 seconds after the loss of consciousness. The Sellick maneuver is held throughout those 30 seconds until medical confirmation that the tube is in the windpipe.

If stomach contents enter the upper airway at any time during an induction of anesthesia, the anesthesiologist will see vomitus in the patient’s mouth or inside the clear plastic facemask. The anesthesiologist may also detect evidence of inadequate oxygen exchange—i.e. the patient’s pulse oximeter readings will decline to less than the safe level of 90%. The anesthesiologist will then suction the upper airway and place a breathing tube into the windpipe as soon as possible. This tube is called an endotracheal tube, and it has a balloon near its tip. When inflated, the balloon protects stomach contents from descending into the lungs.

The anesthesiologist will then suction out the lungs through the inside the breathing tube. Suction catheters of varying length and diameters exist for this purpose. The surgery will likely be cancelled if it has not yet started. If the aspiration of stomach contents occurs in the middle of surgery, it’s likely the surgery will be aborted or shortened.

As I have written in multiple posts on this website, all critical care medicine resuscitation follows the A-B-C mantra of Airway—Breathing—Circulation. The regurgitation of stomach contents interferes with both A and B by blocking the airway and interfering with breathing.

The medical term for fasting prior to surgery is NPO, which stands for “nil per os,” a Latin phrase for nothing per mouth. If you hear your doctor or nurse say, “Is she NPO?” they’re asking the important question of whether you have fasted as required. Being NPO may seem inconvenient and unnecessary, but it’s critical to assure your health and well being during anesthesia.

THE ACHILLES’ HEEL OF ANESTHESIOLOGY… WHAT IS THE GREATEST THREAT TO OUR SPECIALTY?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Anesthesiology is a wonderful profession, as I have described in many previous posts on theanesthesiaconsultant.com. But nothing is perfect, and anesthesia has one threat which could in time undermine the entire specialty. What is this threat? What is anesthesiology’s Achilles’ heel?

No, it’s not the nurse anesthetists, nor the stress of covering surgeries in the middle of the night, nor the stress of saving patients who are trying to die in front of our eyes during acute care emergencies.

Our Achilles’ heel is that we don’t have our own patients.

Primary care doctors have a bevy of patients who return to see them at regular intervals. Specialists and surgeons have a clinic full of patients who are referred to them from primary care physicians. Health care systems are acquiring primary care providers and top specialists as rapidly as they can, to assemble a sizable network of covered lives. This network of patients will serve to keep their clinics and hospitals full and profitable.

In the operating rooms, the patients are brought in by the surgeons. Anesthesia providers, be they physician anesthesiologists or nurse anesthetists, are tasked with providing safe and quality anesthesia care. Anesthesia providers are at best consultants, and at worst, “worker bees” called upon to provide a service.

Which of the following are commodities?

  1. Crude Oil
  2. Copper
  3. Soy beans
  4. Anesthesia services
  5. All of the above

Consider the answer to be E.

To hospital administrators and CEOs, anesthesia “worker bees” can be considered an expense or a commodity, somewhat similar to registered nurses, orderlies, surgical technicians, or even janitors. We can be regarded as a commodity because, like the nurses, technicians, and janitors, patient referrals do not originate with us. To a hospital CEO, each surgeon is an asset who brings surgical patients to surgery, whereas each anesthesia provider may be thought of as a worker necessary to do surgery.

Note that anesthesiologists who specialize in pain medicine in a clinic setting can be exceptions to this discussion. Pain specialists can generate their own patients from their clinics on which to do pain-relieving procedures. In their operating room role they more resemble the niche of a surgeon than that of an anesthetist.

In the current medical economy, when a hospital CEO, a health care system, or a surgery center is looking for anesthesia coverage, a priority is to acquire quality service of these anesthesia “worker bees” at the lowest possible cost. The hospital CEO, health care system, or surgery center may then grant an exclusive contract to the cheapest provider. This exclusive contract may go to a national anesthesia company, rather than the anesthesiologists currently on staff, or this exclusive contract may go to a newly hired anesthesia chairman, empowered to hire a new staff of anesthesiologists or nurse anesthetists at a budget rate.

You may be an outstanding anesthesiologist, but you are replaceable. Your anesthesia group may be an outstanding group, but your whole group is replaceable.

There are problems even if your group has an exclusive contract. Per the California Society of Anesthesiologists’ Dr. Keith Chamberlain, negative aspects of an anesthesia exclusive contract include:

  • “You can lose an exclusive contract. Anesthesia job security is based on quality, service, and (more recently) cost. Today, 80 per cent of anesthesia groups receive some subsidy from hospitals, which are strongly motivated to reduce it. Competitors often approach hospitals with business plans that eliminate the subsidy, and the decision for the hospital often comes down to cost. If your hospital privileges are tied to an exclusive contract, your ability to continue to practice will depend on your relationship with the new contract holder.
  • The contract holder will eventually experience pressure from the hospital to contract with its payers. There may be a phrase in the contract about “cooperation” with payers. Frequently this means that the contract holder must agree to a contract rate—good or bad.
  • If case volume or the number of anesthetizing locations increases, the contract may insist on the availability of additional providers, regardless of OR inefficiency or payer mix.
  • Many standard contracts allow either party to terminate without cause on 90 days following the first anniversary.”

(http://members.csahq.org/blog/2014/07/21/dont-count-exclusive-contract)

An Internet search documents specific examples of anesthesiology groups losing their jobs around the United States:

  • From Oregon, in 2010: “Turmoil at Good Samaritan: Up to 23 anesthesiologists will lose their jobs in September when Legacy Good Samaritan ends its contract with the Oregon Anesthesiology Group. The hospital plans to replace the doctors with nurse anesthetists. Unhappy physicians and their supporters have raised concerns about whether the switch puts cost savings ahead of patient safety (nurses make less than docs). Legacy spokesman Brian Terrett says the hospital will gain more control but not benefit financially from the transition because anesthesia costs are billed to patients. He added that the nurse anesthetists will be fully credentialed and supervised by doctors.” Willamette Week: July 7, 2010(https://www.oregon-crna.org/site/content/23-anesthesiologists-will-lose-their-jobs-september)
  • From the state of Virginia, in 2015: “A conflict between Riverside Regional Medical Center and its former anesthesia company has escalated to the point that Riverside is unable to perform open-heart surgery until April 23. Riverside did not renew its contract with Virginia Anesthesia and Perioperative Care Specialists and last week brought a new anesthesia company on board…. What happened? Riverside Regional Medical Center ended a long-standing relationship with a local anesthesiology group, Virginia Anesthesia and Perioperative Care Specialists, and contracted with a national management company, Soma Health Partners, effective April 7. Texas-based Soma is bringing in new anesthesiologists because, contractually, the local company’s employees cannot join the new company for two years.”( http://www.dailypress.com/news/dp-local_riverside_0415apr15,0,5448759.story?track=rss)
  • From California, in 2011: In her blog, A Penned Point, Dr. Karen Sibert writes “At Kaweah Delta Medical Center in Visalia, hospital administrators put out the anesthesia contract for competitive bidding in 2011, and the all-MD anesthesia group that had held the contract for years lost out to Somnia.  A new anesthesiology chief came on board, and a care team model with nurse anesthetists took over.” (http://apennedpoint.com)

What can anesthesiologists do to respond to this Achilles’ heel threat and create better job security? To reduce the urge for a hospital CEO to displace their current anesthesia providers, you need to:

  1. Provide the highest quality of medical care to your hospital and surgery centers.
  2. Provide high service to your hospital and surgery centers.
  3. Maintain high quality professional relationships with surgeons, other physician specialties, and administrators, so there is little incentive to demand a change.
  4. Become involved in hospital medical committees and politics, both for self-preservation and because these are roles typically filled by physicians, not nurse anesthetists.
  5. Avoid greed in negotiations over contracted rates and hospital stipends. By all means acquire the best deal you can, but realize that unreasonable expectations for monetary reimbursement may give the CEO an incentive to seek bids from a national anesthesia company or an alternative anesthesia group.
  6. Consider moving toward the new Perioperative Surgical Home model, as advocated by the American Society of Anesthesiologists. The PSH is a means for anesthesiologists to become valuable preoperative and postoperative necessities for their health care system, rather than just operating room anesthesia providers (which are easier to replace).

Hospital administrators and CEOs are trained to manage the bottom line. They will consider all reasonable means to reduce expenses. Be aware that your anesthesia group can be seen as a replaceable commodity. Consider points 1 – 6 above, and try not to give your hospital administrator a reason to look elsewhere for anesthesia coverage.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

IS ANESTHESIA AN ART OR A SCIENCE?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Is the practice of anesthesia an art or a science? Is the practice of medicine an art or a science?Over one hundred years ago the father of modern medicine, Dr. William Osler of Johns Hopkins Medical Center, made the following statements: “Medicine is a science of uncertainty and an art of probability,” and “The practice of medicine is an art, based on science.”

 

In my career I’ve practiced three specialties at Stanford: internal medicine, emergency medicine, and anesthesiology. My career has bridged clinics, operating rooms, intensive care units, emergency rooms, and helicopter trauma medicine. I’ve practiced in four different decades.

With all respect to Dr. Osler’s legacy, what I’m witnessing in the clinical arena today tells me 21st century medical practice will be very much about science and very little about art.

A Merriam-Webster dictionary definition of science reads “knowledge about or study of the natural world based on facts learned through experiments and observation.”

An Oxford English dictionary definition of art reads “the various branches of creative activity, such as painting, music, literature, and dance.”

Which of these definitions best fits your medical practice?

To me, the answer is clearly “science.”

I searched through all the secondary definitions of “art” in multiple dictionaries, and found very few definitions of “art” that apply to the practice of medicine. The closest fits were: art is a skill or special ability e.g. a skill at doing a specified thing, typically one acquired through practice, from the Oxford English Dictionary; or art is skill acquired by experience, study, or observation e.g. the art of making friends, from the Merriam-Webster dictionary.

Medical school training consists of four years of intensive study of anatomy, physiology, biochemistry, pharmacology, microbiology, pathology, diseases, and the treatment for diseases. Core classes require extensive memorization and comprehension of complex scientific facts. In the last two years of medical school, clinical classes require the student to apply this complex science while evaluating individual human patients. New skills acquired at this clinical stage are those of interviewing, history taking, physical examination, interpretation of medical test results, differential diagnosis, and application of appropriate therapies. Mastering the doctor-patient interaction requires an education in empathy, effective listening, respect, and conversation about complex medical topics using parlance non-medical laypersons can comprehend.

Creative activities such as painting, music, literature, and dance are absent from the preceding paragraph. There is an “art” to making the correct diagnosis, and there is an “art” to applying empathy, effective listening, respect, and conversing about complex medical topics in language non-medical laypersons can comprehend. In this context, “art” connotes those secondary definitions, as in “a skill at doing a specified thing, typically one acquired through practice.” A talented doctor with years of experience is a skilled artist of medical practice, just as World Series hero Madison Baumgartner is a skilled artist of pitching baseballs. A student entering a career in medicine in the 21st century must prepare herself or himself for the scientific rigors of the job. The opportunity to create is largely absent.

Painters, musicians, authors, and dancers create original art, some of it fantastic and some mundane. In medicine this type of creativity is rare, but it does exist. The medical laboratory researchers who cured smallpox and polio changed the world by creating their discoveries. The medical researchers seeking cures for Alzheimer’s disease, Ebola, or HIV are in a constant quest for the discovery of original ideas. Physician authors such as the Bay Area’s Abraham Verghese (Cutting for Stone) and Khaled Hosseini, (The Kite Runner) wrote outstanding literary works and are very creative. Many physicians express creative skills in their hobbies as musicians, artists, sculptors, actors, dancers, and writers. These physicians earn their living with their primary jobs in medicine, and expend their creative energies in these secondary outlets in their spare time.

A generation ago the ideal physician may have been depicted in the persona of Dr. Marcus Welby, a fictional television doctor. Dr. Welby was the Atticus Finch of medicine, a kind, smiling, gray-haired physician who spent each week’s sixty-minute show working on healing and treating one patient’s problems. His heroic skills were wisdom, intelligence, empathy, and a steadfast dedication to that one patient for the entire TV show each week. Although he was portrayed as a savvy, highly-schooled professional, Dr. Welby thrived by an almost god-like ability to feel his way through a difficult case and create a workable diagnosis and solution. In Dr. Welby’s office practice each patient posed a dilemma he had to solve during an hour-long television episode. In today’s office practice each patient’s complaints must be addressed in a twenty-minute period of time, after which the physician must enter all the information into a cumbersome version of a computerized Electronic Medical Record (EMR) before meeting the next patient for the next twenty-minute encounter.

In the 21st century operating room practice of anesthesiology, we typically have ten minutes to talk to a patient prior to rendering them unconscious. After anesthetic induction the patient is changed into a sleeping human who carries objective values for blood pressure, heart rate, oxygen saturation, respiratory rate, temperature, and exhaled gas concentrations. The practice of anesthesiology becomes very much like a physiology experiment with the twin goals for the patient of a) guaranteeing sleep, while b) striving to maintain perfect vital signs. Where is the art? Is there art in varying techniques to accomplish these goals? Is it an “art” to anesthetize shoulder arthroscopy patient #1 with propofol and sevoflurane, and then to anesthetize shoulder arthroscopy patient #2 with propofol and an interscalene block? Rather than “art,” I’d call this using clinical judgment based on experience and scientific information.

Let me point out several current trends which are moving physician jobs further away from any creativity:

1) The organization of medicine into large corporate practices, with the variability of practice minimized. I recently attended a clinical lecture Stanford Medical Center in which the topic was “Variation is the Enemy of Good.”

2) The goal of organizing patient management into detailed and specific algorithms for physicians to follow, to insure they’re all treating the same medical problems the same way. In the Forbes article Medicine Is An Art, Not A Science: Medical Myth Or Reality?(July 12, 2014), author Robert Pearl MD, the CEO of the Permanente Medical Group, describes the value of protocols for the operating room, for treatment of stroke, and for prevention of heart attack, and concludes “We can predict that doctors who today refuse to follow the national recommendations for treating patients with strokes, heart attacks and a variety of other medical problems will be hard to convert. But we must change their behavior. The health of their patients and our nation depends on it.” Examples of such protocols in anesthesia practice are algorithms introduced for the management of total knee and hip replacement anesthesia, using a combination of neuroaxial block, regional nerve block such as adductor canal block, plus multimodal pain medication regimens (Gandhi and Viscusi, Multimodal Pain Management Techniques in Hip and Knee Arthroplasty, The New York School of Regional Anesthesia (www.nysora.com) Volume 13, J u l y 2009, pages 1-10).

3) A move to a “shift work” mentality in modern medical practice. A generation ago an MD would follow up on his patients until all the work was done for a given day, in addition to being night on-call for patients of his partners or colleagues once a week. In the past I worked for the largest HMO in California. The HMO culture promoted a 40-hour-per-week shift work mentality for physicians. When three p.m. arrived, many doctors signed off to the next doctor coming on duty to take over their job.

4) The promotion of non-physicians into the workforce to perform roles previously handled by MDs. Due to an inadequate supply of primary care doctors, the future of clinic medicine in large corporate medical practices will likely be legions of nurse practitioners and/or physician assistants supplying much of primary care.

5) Pursuit of artificial intelligence in medicine (AIM) as a goal. A recent Wall Street Journal article, IBM Crafts a Role for Artificial Intelligence in Medicine: Deal for Merge Healthcare is step toward training IBM’s Watson software to identify cancer, heart disease (August 11, 2015) described a significant advance in AIM technology. It’s not hard to imagine artificial intelligence computers making diagnoses and treatment decisions in the future.

Are these trends bad? Time will tell. The trends are driven by economics, and don’t expect to see them reverse. Variability will decrease and so will the feeling that medicine is an art.

Let’s hope future generations of physicians will still quote Osler’s claim that “the practice of medicine is an art, based on science.” May empathy, effective listening, respect, and conversation always be critical skills envied and mastered by all physicians.

ON BECOMING AN ANESTHESIOLOGIST… WHAT PERSONAL CHARACTERISTICS ARE ESSENTIAL TO BECOME A SUCCESSFUL ANESTHESIOLOGIST?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

THE ANESTHESIA CONSULTANT

What are the personal characteristics of a successful anesthesiologist? You’ve found The Anesthesia Consultant website, so you have some interest in anesthesia. Perhaps you’ve heard that anesthesiologists earn a comfortable living.

Per wikiprofessionals.org: “According to figures from the U.S. Department of Labor, the lowest 10% of anesthesiologists earn under $135,110 per year, whereas the top 10% earn up to $408,000 per year. The median annual earnings, defined as that figure where half the experienced anesthesiologists earn less than that amount and half earn more, is $292,000. Anesthesiologists’ salaries are among the highest of all U.S. professions.”

Perhaps you’re wondering if anesthesiology is a potential vocation for you, your child, your cousin, or your niece. The truth is: a career in anesthesia involves unique demands that most people would not seek, tolerate, or ever grow accustomed to.

Nonetheless, I believe no medical specialty is more fascinating than anesthesiology. Based on thirty years as an anesthesiologist, here’s my checklist of ten qualities necessary to succeed in this profession.

You must have:

  1. Calmness under intense pressure. I’ve experience countless emergency moments where patients dropped their heart rate or blood pressure dangerously low, increased their heart rate or blood pressure dangerously high, hemorrhaged from an artery, lost their airway, or in some other unexpected way sustained a life-threatening event. An anesthesiologist must remain focused and decisive at these moments. An anesthesiologist must choose the correct diagnostic and therapeutic moves to save the patient’s life. An operating room emergency is not a time for screaming, temper tantrums, or freezing. An operating room emergency is a time for calm, assertive action.
  2. Vigilance during long periods of quasi-boredom. In between those emergency occurrences, an anesthesiologist must remain attentive without becoming bored or distracted. The motto of the American Society of Anesthesiologists is one word: Vigilance. During surgery, much of our job is to observe. One day I brought my 15-year-old son into the operating room with me to observe surgery, hoping he would respect the complex nature of my job. Instead his impression afterward was, “Dad, most of the time you don’t really do much of anything. You watch monitor screens, talk to the surgeon and the nurses, and listen to music.” One of my partners overheard this analysis and remarked, “If you see an anesthesiologist working hard, then you’ve really got a problem!”
  3. Superior skills with your hands. There are no tests during college pre-med classes or medical school clerkships to quantify an individual’s fine motor skills. Many doctors with superior manual dexterity migrate toward operative specialties like surgery or anesthesia. But not all anesthesiologists are equal. Some resident anesthesia doctors are less skillful than others at various anesthesia procedures such as placing breathing tubes into windpipes, inserting catheters into veins and arteries, injecting nerve blocks near peripheral nerves, or injecting spinals and epidurals into the lumbar spine. Residents have dropped out of our specialty altogether because they were not confident with the required procedural skills.
  4. The patience and motivation to persist through 25-27 years of training. In the song Subterranean Homesick Blues, Bob Dylan wrote, “Twenty years of schooling and they put you on the day shift.” In anesthesiology, twenty years of schooling earns you both the dayshift and the night shift. Your education will consist of thirteen years through high school, four years of college, four years of medical school, one year of internship, three years of anesthesia residency, and probably an extra one or two years of fellowship specialization. This cascade of years stretches your education past the age of thirty. You must to be accepting of delayed gratification. During the last of those twenty-five years, when you owe $250,000 in educational debt and are roaming hospital hallways at three a.m., your college classmates who chose business careers are at home sleeping in a house they’ve already purchased.
  5. A tolerance for sleeplessness. You must have the ability to thrive during early mornings and late nights. Scheduled surgeries start early in the morning, usually at 0730. Prior to that hour, anesthesiologists meet, evaluate, and obtain consent from their first patient, and then bring the patient to the operating room and safely render them unconscious. Not all cases start at sunrise—surgical patients get sick around the clock. Emergency surgeries may start at midnight or three o’clock in the morning. Anesthesiologists must be tolerant of fatigue and still be able to work unimpaired.
  6. Compulsive attention to detail. All aspects of anesthesia care, including a) the review of a patient’s medical condition prior to surgery, b) the planning and conduct of the anesthetic, and the management of medical conditions and c) complications immediately after surgery, require the anesthesiologist to avoid mistakes of any kind and to strive for near-perfection. Psychiatrists often diagnose OCD (obsessive-compulsive disorder) in patients. It’s probable that most anesthesiologists have a least a touch of OCD.
  7. Thick skin. You cannot be too hard on yourself, even though anesthesiologists are not allowed to have a bad day. A bad day in this career could mean a dead patient, a comatose patient, or a patient who was supposed to be discharged home instead lying in an intensive care unit on a ventilator. You’re human, and you may make a mistake. That mistake may have no consequence or it may cost a patient dearly. If a patient suffers a bad outcome secondary to a mistake you make, you’ll have to endure the emotional toll. There are stories of anesthesiologists who quit the specialty, become addicts, or commit suicide because a patient suffered a bad outcome. You can’t succumb.
  8. Excellent communication skills. You must be someone who can sell yourself to a patient in ten minutes. Anesthesiologists typically have ten minutes before surgery to interview a patient, examine them, obtain their consent, and gain their trust. The patient will be anxious. You need to assess and manage both their medical and their emotional needs at this demanding moment. An anesthesiologist’s patients are unconscious most of the time, but not all the time. If you want a medical career with zero awake hours of patient contact, consider pathology instead of anesthesiology. A successful anesthesiologist must also cooperate with different teams of surgeons, nurses, and medical techs every day. Surgeon personalities come in all varieties—some are demanding, some are condescending, and some are bullies. You have to work effectively with all types of surgeons, whether you admire that individual’s personality or not.
  9. Intelligence. Admission to anesthesia residency positions is very competitive. In 2014 there were only 1,049 anesthesia PG-1 (Post-Graduate Year 1) residency positions in the United States and 1,836 individuals who applied for these positions. Nearly 50% of applicants—all of them medical school seniors or medical school graduates—failed to land a position in anesthesia. (Ref: Results and Data, National Resident Matching Program 2014 http://www.nrmp.org/wp-content/uploads/2014/04/Main-Match-Results-and-Data-2014.pdf)
  10. A love for helping people. Every physician must have this. We spend years memorizing facts about physiology, disease, and pharmacology, but a successful doctor must care about each patient as an individual. Empathy for patients before, during, and after the day of their surgery and anesthesia is essential.

These are ten qualities I look for in an outstanding anesthesiologist. The next time you need surgery, I’d advise you to look for and expect the same qualities in the man or woman who will anesthetize you.

PubMed is most important medical website on the Internet. If you’re a layperson seeking practical and accurate medical knowledge, you need PubMed. If you’re a medical professional seeking state-of-the-art information from the medical literature, you need PubMed.

PubMed is most important medical website on the Internet.

If you’re a layperson seeking practical and accurate medical knowledge, you need PubMed.

If you’re a medical professional seeking state-of-the-art information from the medical literature, you need PubMed.

There are tens of thousands of medical websites. Some offer truthful, reliable information. Other websites are authored by less reputable sources and can be deceptive. PubMed (http://www.ncbi.nlm.nih.gov/pubmed) is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintains the database. PubMed comprises more than 24 million citations for biomedical literature from MEDLINE, life science journals, and online books.

PubMed is to medical information what Google is to Internet information. Every article published in a reputable medical journal is listed in PubMed, and every article is accessible and discoverable by keywords. The keyword can be an author’s name, a journal name, or most commonly, a medical topic.

For example, if you are interested in information about propofol use for colonoscopy, you would enter PROPOFOL, COLONOSCOPY into the PubMed search window. A list of 253 abstracts of medical journal articles appears in seconds. The abstracts are listed in reverse chronological order, with the most recent listed first. By perusing the 253 abstracts, you’ll have an overview of what peer-reviewed researchers have published on the topic.

This is the first abstract listed under PROPOFOL, COLONOSCOPY:

Gastrointest Endosc. 2015 Apr 4. pii: S0016-5107(15)00058-9. doi: 10.1016/j.gie.2015.01.041. [Epub ahead of print]

Practice patterns of sedation for colonoscopy.

Childers RE1Williams JL1Sonnenberg A1.

Author information

Abstract

BACKGROUND:

Sedative and analgesic medications have been used routinely for decades to provide patient comfort, reduce procedure time, and improve examination quality during colonoscopy.

OBJECTIVE:

To evaluate trends of sedation during colonoscopy in the United States.

SETTING:

Endoscopic data repository of U.S. gastroenterology practices (Clinical Outcomes Research Initiative, CORI database from 2000 until 2013).

PATIENTS:

The study population was made up of patients undergoing a total of 1,385,436 colonoscopies.

INTERVENTIONS:

Colonoscopy without any intervention or with mucosal biopsy, polypectomy, various means of hemostasis, luminal dilation, stent placement, or ablation.

MAIN OUTCOME MEASUREMENTS:

Dose of midazolam, diazepam, fentanyl, meperidine, diphenhydramine, promethazine, and propofol used for sedation during colonoscopy.

RESULTS:

During the past 14 years, midazolam, fentanyl, and propofol have become the most commonly used sedatives for colonoscopy. Except for benzodiazepines, which were dosed higher in women than men, equal doses of sedation were given to female and male patients. White patients were given higher doses than other ethnic groups undergoing sedation for colonoscopy. Except for histamine-1 receptor antagonists, all sedative medications were given at lower doses to patients with increasing age. The dose of sedatives was higher in colonoscopies associated with procedural interventions or of long duration.

LIMITATIONS:

Potential for incomplete or incorrect documentation in the database.

CONCLUSION:

The findings reflect on colonoscopy practice in the United States during the last 14 years and provide an incentive for future research on how sex and ethnicity influence sedation practices.

A similar abstract precedes almost every medical journal article in its original publication format. PubMed catalogs these abstracts for readers. The original medical journal articles with the full text of the study are rarely available online. Libraries, individual scientists, and physicians subscribe to the actual journals. With PubMed, the summaries of articles published in journals are available to all readers on the Internet for free.

Prior to the Internet, researching medical topics was a tedious and difficult process requiring many hours of paging through hard copies of medical journals stored in university medical libraries. I subscribed to top journals in my specialties, e.g. the New England Journal of Medicine, or Anesthesiology. I read these journals weekly, tore out the pages of the most important articles, and stored these in a file cabinet in my office.

With PubMed, those days are gone.

I utilize PubMed almost every day in researching clinical problems for patient care, preparing lectures, writing articles, and authoring this website. If you’re a medical professional, I recommend you rely on PubMed for the same reasons.

If you’re a layperson, Google will often direct you to medical information websites such as WebMD, HealthCentral, or Wikipedia. I recommend you set a bookmark for PubMed. Laypeople can understand most of the terminology in PubMed. If you have difficulty, I recommend you Google the words you are puzzled with, and continue to increase your knowledge base as you read on.

There’s an enormous, vivid world of medical data out there. Get on the PubMed train and keep educating yourself!

BLOOD PRESSURE DROPS TO 85/45 FOLLOWING THE INDUCTION OF ANESTHESIA: WHAT DO YOU DO?

THE ANESTHESIA CONSULTANT

CLINICAL CASE: You’re scheduled to anesthetize a healthy 55-year-old female for an appendectomy. Her blood pressure is 150/90 on admission. In the operating room, you induce anesthesia with your standard recipe of 2 mg of midazolam, 100 mcg of fentanyl, 200 mg of propofol, and 40 mg of rocuronium, and intubate the trachea. Five minutes after induction and 15-30 minutes before the surgical incision will occur, her blood pressure drops to 85/45. Is this a problem? What will you do? What level of hypotension is acceptable to you?

Low blood pressure in surgery

DISCUSSION: During surgery, anesthesiologists balance their administration of drugs to the level of surgical stimulation the patient is experiencing. The placement of an endotracheal tube is an intense stimulus to an awake patient, but only a moderate stimulus to an anesthetized patient. After the placement of an endotracheal tube, a lag time of fifteen minutes to thirty minutes or more occurs prior to surgical incision. During this interval, the blood pressure sometimes sags.

Let’s look at the anesthesia literature to learn what has been described about this problem.

David Reich, et al of Mt. Sinai Hospital in New York queried the computerized anesthesia records of 4,096 patients undergoing general anesthesia and analyzed the incidence of hypotension in the period immediately after induction. (Predictors of hypotension after induction of general anesthesia Anesth Analg. 2005 Sep;101(3):622-8). The median blood pressure (MAP) was determined before anesthesia induction, during the first 5 minutes after induction, and also the period from 5-10 minutes after induction. Hypotension was defined as either (1) a mean arterial blood pressure (MAP) decrease of >40% and MAP

Statistically significant predictors of hypotension after anesthetic induction included: ASA III-V, baseline MAP

Dr. Reich wrote, “association with mortality alone was not reported in the manuscript but was nearly statistically significant (P = 0.066). The majority of our colleagues apparently believe that transient hypotension is inconsequential to outcomes. Although limited by the problems associated with retrospective studies, the results of our study provide preliminary evidence that runs counter to the prevailing wisdom regarding transient severe hypotension during general anesthesia.”

What level of hypotension is unsafe for patients?

The effects of hypotension in nonsurgical subjects was studied in 1954 (Finnerty, FA, Cerebral Hemodynamics during Cerebral Ischemia Induced by Acute Hypotension1 Clin Invest. 1954 Sep; 33(9): 1227–1232). Young and old experimental subjects were subjected to increasing degrees of hypotension until clinical signs of cerebral ischemia developed. Hypotension was induced by intravenous administration of the anti-hypertensive medication hexamethonium. The authors discovered a linear relation between pre-hypotensive blood pressure and the level of induced hypotension that produced clinical signs of cerebral ischemia such as yawning, sighing, staring, confusion, inability to concentrate, inability to perform simple commands, nausea, dizziness, and involuntary body movements. Their data revealed that the safe level of hypotension was no lower than about 2/3 of the resting blood pressure before inducing hypotension. At 2/3 of their pre-procedure MAP, patients reached a threshold of clinical cerebral ischemia, with onset of yawning, sighing, staring, confusion, inability to concentrate, and inability to carry out simple commands. Because these studies were done on unanesthetized humans, it’s impossible to equate the data to patients with surgical anesthesia. Surgical patients have a different etiology for their hypotension, as well as reduced cerebral oxygen consumption from general anesthetic drugs. This explains why most surgical patients fail to manifest any cerebral damage resulting from episodes of hypotension occasionally following the induction of anesthesia.

The problem of hypotension and refractory hypotension following induction of anesthesia is currently being studied in an ongoing clinical trial at the University of Iowa. (ClinicalTrials.gov identifier: NCT02416024, contact Kenichi Ueda, MD, kenichi-ueda@uiowa.edu). Induction agents in this study will include 1.5 mg/kg propofol, 2 mcg/kg fentanyl, 100 mg lidocaine, and 0.6 mg/kg rocuronium. Inhaled anesthetic will be sevoflurane at 0.5 MAC with 5L/min of 100% oxygen starting at mask ventilation till 10 minutes after tracheal intubation. Blood pressure will be measured by a brachial cuff prior to induction and every minute after intubation for 10 minutes. If the systolic pressure drops below 90 mmHg or more than 25% from baseline, the patient will be classified in the study as “Hypotensive.” Conversely, if the patient’s systolic blood pressure does not drop below 90 mmHg more than 25% from baseline within 10 minutes of intubation, the patient will be classified as “Not Hypotensive.” In attempt to bring systolic blood pressure up to above 90 mmHg or more than 25% from baseline in “hypotensive” patients, the anesthetic provider will use 100 mcg of phenylephrine (or 5 mg ephedrine if heart rate < 50 bpm) within 10 minutes of intubation. If over 200 mcg of phenylephrine (or 10 mg ephedrine) has been used without a return of the systolic brachial blood pressure >90 mmHg or more than 25% from baseline, the patient will be classified in the study as “Refractory Hypotensive.” Look for the results of this trial to be published in years to come.

Based on the data reviewed in this column, it seems advisable to maintain a patient’s mean arterial pressure at or above a level of 2/3 of their baseline pressure. What if the patient’s baseline blood pressure in their outpatient clinic notes is 120/80 (MAP=93) yet in the pre-operative room on admission to surgery their blood pressure is 150/90 (MAP=110)? This is not an uncommon occurrence, as blood pressure often spikes secondary to the inevitable anxiety which accompanies a pending surgery. Is the anesthesia provider compelled to maintain the blood pressure at 2/3 of 110 = 73 after induction, or compelled to maintain the blood pressure at 2/3 of 93 = 62 after induction? I can find no specific data to answer this question. In my experience, after the administration of 2 mg of intravenous midazolam the hypertensive 150/90 often decreases to the 120/80 (MAP=93) range. With this MAP = 93 value as the baseline blood pressure, 2/3 X 93 = 62 would be the lowest level of MAP I’d feel comfortable with. We’re trained to treat post-induction hypotension with a vasopressor. Typically phenylephrine 100 mcg will increase the pressure to its preinduction level. Some patients require more than one dose of phenylephrine.

Let’s return to the management of your Clinical Case above.

  1. You choose to administer a dose of phenylephrine 100 mcg IV, and the blood pressure returns to 110/70. You maintain general anesthesia depth with the inhaled anesthetic sevoflurane at 0.5 MAC with 5L/min of 100% oxygen.
  2. Five minutes later the blood pressure drops to 85/45 again, and you repeat a dose of phenylephrine 100 mcg IV.
  3. When the surgery begins, the blood pressure increases to 150/90, and you treat by increasing anesthesia depth.
  4. Note that per the Reich data above, the incidence of hypotension increased with higher doses of fentanyl at induction (5-5.0 mcg/kg fentanyl vs. 0-1.5 mcg/kg fentanyl). I’ve found that the lower dose range of fentanyl, specifically zero fentanyl at induction, works very well for many patients. Incremental doses of propofol alone blunt the transient hypertensive response to laryngoscopy and intubation, and the lack of fentanyl leads to less hypotension in the ten minutes post-intubation. Appropriate levels of narcotics are then titrated in when surgery commences and the surgical stimulus increases. Also per Reich’s data, for patients age 50 or older who are ASA III-V, or for patients who present with a baseline pre-operative MAP.

WILL YOU HAVE A BREATHING TUBE DOWN YOUR THROAT DURING YOUR SURGERY?

THE ANESTHESIA CONSULTANT

One of the most common questions I hear from patients immediately prior to their surgical anesthetic is, “Will I have a breathing tube down my throat during anesthesia?”

The answer is: “It depends.”

placing anesthesia breathing tube

Let’s answer this question for some common surgeries:

KNEE ARTHROSCOPY: Common knee arthroscopy procedures are meniscectomies and anterior cruciate ligament reconstructions. Anesthetic options include general anesthesia, regional anesthesia, or local anesthesia. Most knee arthroscopies are performed under a general anesthetic, in which the anesthesiologist injects propofol into your intravenous line to make you fall asleep. After you’re asleep, the most common airway tube used for knee arthroscopy is a laryngeal mask airway (LMA). The LMA in inserted into your mouth, behind your tongue and past your uvula, to a depth just superior to your voice box. The majority of patients will breath on their own during surgery. The LMA keeps you from snoring or having significant obstruction of your airway passages. In select patients, including very obese patients, an endotracheal tube (ETT) will be inserted instead of an LMA. The ETT requires the anesthesiologist to look directly into your voice box and insert the tube through and past your vocal cords. With either the LMA or the ETT, you’ll be asleep and will have no awareness of the airway tube except for a sore throat after surgery. A lesser number of knee arthroscopies are performed under a regional anesthetic which does not require a breathing tube. The regional anesthetic options include a blockade of the femoral nerve located in your groin or numbing the entire lower half of your body with a spinal or epidural anesthetic injected into your low back. A small number of knee arthroscopies are done with local anesthesia injected into your knee joint, in combination with intravenous sedative medications into your IV. Why are most knee arthroscopies performed with general anesthesia, which typically requires an airway tube? Because in an anesthesiologist’s hands, an airway tube is a common intervention with an acceptable risk profile. A light general anesthetic is a simpler anesthetic than a femoral nerve block, a spinal, or an epidural anesthetic.

Laryngeal Mask Airway (LMA)

Endotracheal Tube (ETT)

NOSE AND THROAT SURGERIES SUCH AS TONSILLECTOMY AND RHINOPLASTY: Almost all nose and throat surgeries require an airway tube, so anesthetic gases and oxygen can be ventilated in and out through your windpipe safely during the time the surgeon is working on these breathing passages.

ABDOMINAL SURGERIES, INCLUDING LAPAROSCOPY: Almost all intra-abdominal surgeries require an airway tube to guarantee adequate ventilation of anesthetic gases and oxygen in and out of your lungs while the surgeon works inside your abdomen.

CHEST SURGERIES AND OPEN HEART SURGERIES: Almost all intra-thoracic surgeries require an airway tube to guarantee adequate ventilation of anesthetic gases and oxygen in and out of your lungs while the surgeon works inside your chest.

TOTAL KNEE REPLACEMENT AND TOTAL HIP REPLACEMENT: The majority of total knee and hip replacement surgeries are performed using spinal, epidural and/or nerve block anesthesia anesthesia to block pain to the lower half of the body. The anesthesiologist often chooses to supplement the regional anesthesia with intravenous sedation, or supplement with a general anesthetic which requires an airway tube. Why add sedation or general anesthesia to the regional block anesthesia? It’s simple: most patients have zero interest in being awake while they listen to the surgeon saw through their knee joint or hammer their new total hip into place.

CATARACT SURGERY: Cataract surgery is usually performed using numbing local anesthetic eye drop medications. Patients are wake or mildly sedated, and no airway tube is used.

COLONOSCOPY OR STOMACH ENDOSCOPY: These procedures are performed under intravenous sedation and almost never require an airway tube.

HAND OR FOOT SURGERIES: The anesthesiologist will choose the simplest anesthetic that suffices. Sometimes the choice is local anesthesia, with or without intravenous sedation. Sometimes the choice will be a regional nerve block to numb the extremity, with or without intravenous sedation. Many times the choice will be a general anesthetic, often with an airway tube. An LMA is used more frequently than an ETT.

CESAREAN SECTION: The preferred anesthetic is a spinal or epidural block which leaves the mother awake and alert to bond with her newborn immediately after childbirth. If the Cesarean section is an urgent emergency performed because of maternal bleeding or fetal distress, and there is inadequate time to insert a spinal or epidural local anesthetic into the mother’s lower back, a general anesthetic will be performed. An ETT is always used.

PEDIATRIC SURGERIES: Tonsillectomies are a common procedure and require a breathing tube as described above. Placement of pressure ventilation tubes into a child’s ears requires general anesthetic gases to be delivered via facemask only, and no airway tube is required. Almost all pediatric surgeries require general anesthesia. Infants, toddlers, and children need to be unconscious during surgery, for emotional reasons, because their parents are not present. The majority of pediatric general anesthetics require an airway tube.

CONCLUSIONS: The safe placement of airway tubes for multiple of types of surgeries, in patients varying from newborns to 100-year-olds, is one of the reasons physician anesthesiologists train for many years.

Prior to surgery, some patients are alarmed at the notion of such a breathing tube invading their body. They fear they’ll be awake during the placement of the breathing tube, or that they’ll choke on the breathing tube.

Be reassured that almost every breathing tube is placed after your unconsciousness is assured, and breathing tubes are removed prior to your return to consciousness. A sore throat afterward is common, but be reassured this is a minor complaint that will clear in a few days.

If you have any questions, be sure to discuss them with your own physician anesthesiologist when you meet him or her prior to your surgical procedure.

“Anesthesiologist” is absent from every list. This is a public relations failure for our specialty. The challenges and stressors anesthesia professionals face every day are seemingly unknown to the media and the populace.

I’ll admit there are pressures involved with being a taxi driver, a news reporter, a photo journalist, an events coordinator, or a public relations executive. Being a working parent is a challenge, although in Northern California where I live millions of adults are working parents because both husbands and wives have to work to pay hefty Bay Area living expenses. But none of these jobs involve the risk and possibility of their clients dying each and every day.

Every surgical patient requires the utmost in vigilance from their physician anesthesiologist in order to prevent life-threatening disturbances of Airway-Breathing-Circulation. The public perceives surgeons as holding patients’ life in their skilled hands, and they are correct. But most surgeons spend the majority of their work time in clinics and on hospital wards attending to pre-operative and post-operative patients. On the 1 – 3 days a week most surgeons spend operating, they are joined in the operating room by anesthesiologists who attend to surgical patients’ lives every day.

Surgeons in trauma, cardiac, neurologic, abdominal, chest, vascular, pediatric, or microsurgery specialties have intense pressure during their hours in the operating room, but each time they don their sterile gloves and hold a scalpel, an anesthesiologist is there working with them.

What follows is my own personal “Top 10 Most Stressful” list, a list of the Most Stressful Anesthesia Situations based on my thirty years of anesthesia practice. Anesthesia practice has been described as 99% boredom and 1% panic, (http://theanesthesiaconsultant.com/is-anesthesia-99-boredom-and-1-panic) and the 1% panic times can be frightening. Read through this list. I believe it will convince you that the job of an anesthesiologist deserves to be on everyone’s Top 10 Most Stressful Jobs list.

TOP 10 MOST STRESSFUL SITUATIONS IN AN ANESTHESIOLOGIST’S JOB

  1. Emergency general anesthesia in a morbidly obese patient. Picture a 350-pound man with a bellyful of beer and pizza, who needs an emergency general anesthetic. When a patient with a Body Mass Index (BMI) > 40 needs to be put to sleep urgently, it’s dangerous. Oxygen reserves are low in a morbidly obese patient, and if the anesthesiologist is unable to place an endotracheal tube safely, there’s a genuine risk of hypoxic brain damage or cardiac arrest within minutes.
  1. Liver transplantation. Picture a patient ill with cirrhosis and end-stage-liver-failure who needs a complex 10 to 20-hour-long abdominal surgery, a surgery whichfrequently demands massive transfusion equal to one blood volume (5 liters) or more. These cases are maximally stressful in both intensity and duration.
  1. An emergency Cesarean section under general anesthesia in the wee hours of the morning. Picture a 3 a.m. emergency general anesthetic on a pregnant woman whose fetus is having cardiac decelerations (a risky slow heart rate pattern). The anesthesiologist needs to get the woman to sleep within minutes so the baby can be delivered by the obstetrician. Pregnant women have full stomachs and can have difficult airway because of weight changes and body habitus changes of term pregnancy. If the anesthesiologist mismanages the airway during emergency induction of anesthesia, both the mother and the child’s life are in danger from lack of oxygen within minutes.
  1. Acute epiglottitis in a child. Picture an 11-month-old boy crowing for every strained breath because the infection of acute epiglottis has caused swelling of his upper airway passage. These children arrive at the Emergency Room lethargic, gasping for breath, and turning blue. Safe anesthetic management requires urgently anesthetizing the child with inhaled sevoflurane, inserting an intravenous line, and placing a tracheal breathing tube before the child’s airway shuts down. A head and neck surgeon must be present to perform an emergency tracheostomy should the airway management by the anesthesiologist fails.
  1. Any emergency surgery on a newborn baby. Picture a one-pound newborn premature infant with a congenital defect that is a threat to his or her life. This defect may be a diaphragmatic hernia (the child’s intestines are herniated into the chest), an omphalocele (the child’s intestines are protruding from the anterior abdominal wall, spina bifida (a sac connected to the child’s spinal cord canal is open the air through a defect in the back), or a severe congenital heart disorder such as a transposition of the great vessels (the major blood vessels: the aorta, the vena cavas and the pulmonary artery, are attached to the heart in the wrong locations). Anesthetizing a patient this small for surgeries this big requires the utmost in skill and nerve.
  1. Acute anaphylaxis. Picture a patient’s blood pressure suddenly dropping to near zero and their airway passages constricting in a severe acute asthmatic attack. Immediate diagnosis is paramount, because intravenous epinephrine therapy will reverse most anaphylactic insults, and no other treatment is likely to be effective.
  1. Malignant Hyperthermia. Picture an emergency where an anesthetized patient’s temperature unexpectedly rises to over 104 degrees Fahrenheit due to hypermetabolic acidotic chemical changes in the patient’s skeletal muscles. The disease requires rapid diagnosis and treatment with the antidote dantrolene, as well as acute medical measures to decrease temperature, acidosis, and high blood potassium levels which can otherwise be fatal.
  1. An intraoperative myocardial infarction (heart attack). Picture an anesthetized 60-year-old patient who develops a sudden drop in their blood pressure due to failed pumping of their heart. This can occur because of an occluded coronary artery or a severe abnormal rhythm of their heart. Otherwise known as cardiogenic shock, this syndrome can lead to cardiac arrest unless the heart is supported with the precise correct amount of medications to increase the pumping function or improve the arrhythmia.
  1. Any massive trauma patient with injuries both to their airway and to their major vessels. Picture a motorcycle accident victim with a bloodied, smashed-in face and a blood pressure of near zero due to hemorrhage. The placement of an airway tube can be extremely difficult because of the altered anatomy of the head and neck, and the management of the circulation is urgent because of the empty heart and great vessels secondary to acute bleeding.
  1. The syndrome of “can’t intubate, can’t ventilate.” You’re the anesthesiologist. Picture any patient to whom you’ve just induced anesthesia, and your attempt to insert the tracheal breathing tube is impossible due to the patient’s anatomy. Next you attempt to ventilate oxygen into the patient’s lungs via a mask and bag, and you discover that you are unable to ventilate any adequate amount of oxygen. The beep-beep-beep of the oxygen saturation monitor is registering progressively lower notes, and the oximeter alarms as the patient’s oxygen saturation drops below 90%. If repeated attempts at intubation and ventilation fail and the patient’s oxygen saturation drops below 85-90% and remains low, the patient will incur hypoxic brain damage within 3 – 5 minutes. This situation is the worst-case scenario that every anesthesia professional must avoid if possible. If it does occur, the anesthesia professional or a surgical colleague must be ready and prepared to insert a surgical airway (cricothyroidotomy or tracheostomy) into the neck before enough time passes to cause irreversible brain damage.

So goes my list of Top 10 List of Stressful Anesthesia situations. If you’re an anesthesia professional, what other cases would you include on the list? Which cases would you delete? How many of these situations have you personally experienced?

This Top 10 Stressful Situations in Anesthesiology list should be enough to convince you that “Anesthesiologist” belongs on everyone’s Most Stressful Jobs list.

I would reassemble the Top 10 List of Most Stressful Jobs to be as follows:

HOW DO YOU START A PEDIATRIC ANESTHETIC WITHOUT A SECOND ANESTHESIOLOGIST?

THE ANESTHESIA CONSULTANT

Clinical Case: In your first week in community practice post-residency and fellowship, you’re scheduled to anesthetize a 4-year-old for a tonsillectomy. You’ll start the anesthetic without an attending or a second anesthesiologist. How do you start a pediatric anesthetic alone?

 

Discussion: During residency it’s standard to initiate pediatric cases with an attending at your right hand to mentor and assist you through the induction of anesthesia. The second pair of hands is critical—one of you manages the airway for the inhalation induction, and the second anesthesiologist starts the IV. In community practice you’ll have to manage all this yourself.

A significant percentage of pediatric anesthetics are performed in regional hospitals and surgery centers rather than in pediatric tertiary hospitals. How does the community practice of pediatric anesthesia differ from pediatric anesthesia in residency?

In community practice you’ll likely telephone the parents the night prior to surgery to discuss the anesthetic. It’s uncommon for a 4-year-old and his family to visit any pre-anesthesia clinic. You’ll take a history over the phone from the parents, explain the basics of anesthetic care, and answer any questions they have.

On the morning of surgery you’ll meet the parents and the child. It’s likely you’ll prescribe an oral midazolam premedication. You’ll set up your operating room with appropriate sized pediatric equipment, heeding the M-A-I-D-S mnemonic for Machine and Monitors-Airway-IV-Drugs-Suction.

What about a request from the mother and/or father to accompany the child into the operating room? This author advises against bringing parents into the O.R. Instead premedicate the child to minimize the emotional trauma of separation from the parent(s), and explain that the duration of time from when they hand you their child to when the gas mask is applied will only be a few minutes.

It’s common to induce anesthesia with the child in a sitting position. The one most important monitor you can place prior to induction is the pulse oximeter. Once unconsciousness is attained, the child is laid supine and a pretracheal stethoscope, the ECG leads, and the blood pressure cuff are applied. If you’re not using a pretracheal stethoscope during mask inductions, let me recommend it to you. No other monitor gives you immediate information on the patency of the airway like the stethoscope does. You can remedy partial or total airway obstruction more promptly than if you wait for oxygen desaturation or end-tidal CO2 changes.

Most children have an easy airway and require no more than occasional positive airway pressure via the mask to keep spontaneous ventilation open. Young children scheduled for tonsillectomy sometimes carry the diagnosis of obstructive sleep apnea (OSA) based on a clinical history of snoring, noisy breathing, or daytime somnolence. It’s uncommon for these patients to have a formal sleep study to document OSA. OSA children may have more challenging airways and have an increased incidence of partial airway obstruction during inhalation induction.

In residency I was taught to supplement the potent volatile anesthetic (halothane in decades past) with 50-70% nitrous oxide. Because the blood:gas partition coefficient of sevoflurane is 0.65, comparable to nitrous oxide’s 0.45, anesthetic induction with sevoflurane alone is nearly as fast as sevoflurane-nitrous oxide. The addition of nitrous oxide to the induction mix is unnecessary, and using an FIO2 of 1.0 affords an extra cushion of oxygen reservoir if the airway is difficult or if the airway is lost.

How will you start the IV after induction? There are several options: 1) You can ask the surgeon or a nurse to start the IV. In my experience, neither surgeons nor O.R. nurses are as skilled in starting pediatric IV’s as an anesthesiologist is, so I don’t recommend this plan; 2) You can ask the surgeon or the O.R. nurse to hold the mask and manage the airway while you start the IV. This option is safe if the airway is easy and you trust the airway skills of the other individual; 3) You can stand at your normal anesthesia position, hold the mask over the patient’s airway with your left hand, and ask the nurse to bend the patient’s left arm back toward you. The nurse tourniquets the patient’s arm at the wrist, and with your right hand you perform a one-handed IV start in the back of the patient’s left hand; 4) The option I feel most comfortable with is to fit mask straps behind the patient’s head, and secure the mask in place with the four straps after the patient is fully anesthetized (when their eyes have returned to a conjugate gaze). While the straps hold the mask in place, you listen to the patient’s breathing via the pretracheal stethoscope to assure yourself that the airway is patent. Then move to the left-hand side of the table and start the IV in the child’s left arm. The typical length of time away from the airway should be less than one minute. If the child has no obvious veins, fit the automated blood pressure cuff (in stat mode) on top of the tourniquet on the upper arm. The BP cuff is a superior tourniquet and the inflated cuff makes it easier to find a suitable vein.

Once the IV is in place, proceed with intubating the patient. In community practice the surgical duration of tonsillectomies can be very short, so the choice of muscle relaxant is important. Succinylcholine carries a black box warning for non-emergent use in children, and should not be used for elective intubation. You can: 1) administer rocuronium and later reverse the paralysis with neostigmine plus atropine; 2) administer a dose of propofol, e.g. 2 mg/kg, which blunts airway reflexes enough to allow excellent intubating conditions in most patients; or 3) you can do perform two laryngoscopies, the first to inject 1 ml of 4% lidocaine from a laryngotracheal anesthesia (LTA) kit, and another 30 seconds later to place the endotracheal tube in the now-anesthetized trachea. Some anesthesiologist/surgeon teams prefer an LMA rather than an endotracheal tube. LMA use for tonsillectomy is not routine in our practice, but one advantage is that an LMA does not require paralysis for insertion.

What if you’re working alone and your patient develops acute oxygen desaturation with airway obstruction and/or laryngospasm during inhalation induction before any IV has been placed? What do you do?

If you anesthetize enough children you will have this experience, and it can be frightening. The immediate management is to inject succinylcholine 4 mg/kg plus atropine 0.02 mg/kg intramuscularly, usually into the deltoid. Then you do your best to improve mask ventilation using an oral airway or LMA if necessary. The oxygen saturation may dip below 90% for a short period of time while you wait for the onset of the intramuscular paralysis. Once muscle relaxation is achieved, ventilation should be successful and the oxygen saturation will climb to a safe level. The trachea can then be intubated, and an IV can be started following the intubation.

If such a desaturation occurs, should you cancel the case? It depends. I’d recommend cancelling the case if: 1) the duration of the oxygen saturation was so prolonged that you are worried about hypoxic brain damage; or 2) gastric contents are present in the airway and you are concerned with possible pulmonary aspiration.

Working pediatric cases alone is rewarding as well as stressful. Nothing in my practice brings me as much joy as walking into the waiting room following a pediatric case to inform parents their child is awake and safe. The parents are relieved, and watching the mother-child reunion minutes later in the Post Anesthesia Care Unit is a heart-warming experience.

Not all anesthesiologists will choose to do pediatric cases during their post-residency career. If you will be anesthetizing children alone in community practice, it’s a good idea toward the end of your anesthesia residency or fellowship to ask your pediatric anesthesia attending keep their hands off during induction, so you can hone your skills managing both the airway and IV. That way you’ll be ready and capable of inducing a child alone after you leave training.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

THE ANESTHESIA CONSULTANT

At weddings you’ll often hear a Bible verse that reads, “And now these three remain: faith, hope and love. But the greatest of these is love.” (1 Corinthians 13:13) A parallel verse in the bible of acute care medicine would read, “Emergencies are managed by airway, breathing, and circulation. But the greatest of these is airway.” The objective of this column is to help you avoid airway lawsuits.

 

Every health care professional learns the mantra of airway-breathing-circulation. Anesthesiologists are the undisputed champions of airway management. This column is to alert you that avoiding even one airway disaster during your career is vital.

Following my first deposition in a medical-legal case years ago, I was descending in the elevator and a man in a suit asked me what I was doing in the building that day. I told him I’d just testified as an expert witness. He asked me what my specialty was, and I told him I was an anesthesiologist. The whistled through his teeth and smirked. “Anesthesia,” he said, “Huge settlements!”

I’ve consulted on many medical malpractice cases which involved death or brain damage, and airway mishaps were the most common etiology. It’s possible for death or brain damage to occur secondary to cardiac problems (e.g. shock due to heart attacks or hypovolemia), or breathing problems (e.g. acute bronchospasm or a tension pneumothorax), but most deaths or brain damage involved airway problems. Included are failed intubations of the trachea, cannot-intubate-cannot-ventilate situations, botched tracheostomies, inadvertent or premature extubations, aspiration of gastric contents into unprotected airways, or airways lost during sedation by non-anesthesia professionals.

Google the keywords “anesthesia malpractice settlement,” and you’ll find multiple high-profile anesthesia closed claims, most of them related to airway disasters. Examples from such a Google search include:

  1. The Chicago Daily Law Bulletin featured a multimillion-dollar verdict secured by the family of a woman who died after being improperly anesthetized for hip surgery. The anesthesiologist settled prior to trial, resulting in the family being awarded a total of $11.475 million for medical negligence. The 61-year-old mother and wife was hospitalized in Chicago for elective hip replacement surgery.  Because of a prior bad experience with the insertion of a breathing tube for general anesthesia, she requested a spinal anesthetic. Her anesthesiologist had trouble inserting a needle for the spinal anesthesia, so he went ahead with general anesthesia. The anesthesiologist was then unable, after several attempts, to insert the breathing tube. He planned to breathe for her through a mask and let her wake up to breathe on her own.  A second anesthesiologist came into the room and decided to attempt the intubation. He tried but was also unsuccessful. Finally, a third anesthesiologist came into the operating room and tried inserting the breathing tube several times. He too was unsuccessful. All of the attempts at inserting the tube caused the tissues in her airway to swell shut, blocking off oxygen and causing cardiac arrest. She suffered severe brain damage and died.
  2. $20 Million Verdict Reached in Medical Malpractice Lawsuit Against Anesthesiologist. A jury returned a $20 million verdict in an anesthesia medical malpractice lawsuit filed by the family of a woman who died during surgery when bile entered her lungs. The wrongful death lawsuit alleged that the anesthetists failed to identify that the victim had risk factors for breathing fluid into her lungs, despite the information being available in her medical record. The victim was preparing to receive exploratory surgery to determine the cause of severe stomach pains when she received the anesthesia. Once anesthetized, she began breathing bile into her lungs. She then later died. The jury awarded $20 million in favor of the plaintiff.
  3. A $35 million medical malpractice settlement was matched by only one other as the largest settlement for a malpractice case in Illinois, and the most ever paid by the County of Cook for a settlement of a personal injury case. The client, a 28-year-old woman, suffered severe brain damage from the deprivation of oxygen resulting from the failure of an anesthesiologist to properly secure an intubation tube. The client, immediately following the occurrence, was in a persistent vegetative state from which the likelihood of recovery was virtually nil. Miraculously, she regained much of her cognitive functioning, although still suffering from significant physiological deficits requiring attendant care for the rest of her life.
  4. Anesthesia Death Results in $2 Million Settlement: 36-Year-Old Man Dies From Anesthesia Mishap Following Elective Hernia Repair Surgery. The plaintiff’s decedent was a 36-year-old man who died secondary to respiratory complications following an elective hernia repair. During the pre-operative anesthesia evaluation, the defendant noted the patient had never been intubated and had required a tracheostomy for a previous surgery. The defendant decided to administer general endotracheal anesthesia with rapid sequence induction. The surgery itself was without incident. Following extubation, the patient began to have difficulty breathing. The patient desaturated. The surgeon was called back to the OR to perform  a tracheostomy, however, there was no improvement in the patient’s oxygenation and he continued to have asystole. Subsequently, he went into respiratory arrest and coded. The code and CPR were unsuccessful, and the patient was pronounced dead.

Per Miller’s Anesthesia, failure to secure a patent airway can result in hypoxic brain injury or death in only a few minutes. Analysis of the American Society of Anesthesiologists (ASA) Closed Claims Project database shows that the development of an airway emergency increases the odds of death or brain damage by 15-fold. Although the proportion of claims attributable to airway-related complications has decreased over the past thirty years since the adoption of pulse oximetry, end-tidal-CO2 monitoring, and the ASA Difficult Airway Algorithm, airway complications are still the second-most common cause of malpractice claims. (Miller’s Anesthesia, Chapter 55, Management of the Adult Airway, 2014).

In 2005, in the ASA-published Management of the Difficult Airway: A Closed Claims Analysis (Petersen GN, et al, Anesthesiology 2005; 103:33–9), the authors examined 179 claims for difficult airway management between 1985 and 1999. The timing of the difficult airway claims was: 67% upon induction, 15% during surgery, 12% at extubation, and 5% during recovery. Death or brain damage during induction of anesthesia decreased 35% in 1993–1999 compared with 1985–1992, but death or brain damage from difficult airway management during the maintenance, emergence, and recovery periods did not decrease during this second period. There is no denominator to compare with the numerator of the number of closed claims, so the prevalence of airway disasters was unknown.

Awake intubation is touted as the best strategy for elective management of the difficult airway for surgical patients. Fiberoptic scope intubation of the trachea in an awake, spontaneously ventilating patient is the gold standard for the management of the difficult airway. (Miller’s Anesthesia, Chapter 55, Management of the Adult Airway, 2014). Awake intubation is a useful tool to avert airway disaster on the oral anesthesiology board examination. Dr. Michael Champeau, one of my partners, has been an American Board of Anesthesiology Senior Examiner for over two decades. He tells me that oral board examinees choose awake intubation for nearly every difficult airway. This is wise–it’s hard to harm a patient who is awake and breathing on their own. Is the same strategy as easily implemented outside of the examination room? In actual clinical practice, an awake intubation may be a tougher sell. Awake intubations are time-consuming, require patience and understanding from the surgical team, and can be unpleasant to a patient who will be conscious until the endotracheal tube reaches the trachea–an event which can cause marked coughing, gagging, hypertension and tachycardia in an under-anesthetized person. As anesthesia providers, we perform hundreds of asleep intubations per year, and only a very small number of awake intubations. Inertia exists pushing anesthesia providers to go ahead and inject the propofol on most patients, rather than to take the time to topically anesthetize the airway and perform an awake intubation. But if you’ve ever lost the airway on induction and wound up with a “cannot intubate-cannot ventilate” patient, you’ll understand the wisdom in opting for an awake intubation on a difficult airway patient.

I refer you to Chapter 55 of Miller’s Anesthesia for a detailed treatise on the assessment and management of airways, which is beyond the scope of this column. In addition to the reading of Chapter 55, I offer the following clinical pearls based on my 30 years of practice and my experience at reviewing malpractice cases involving airway tragedies:

  1. Become skilled at assessing each patient’s airway prior to anesthesia induction. Pertinent information may be in the old chart or the patient’s oral history as well as in the physical examination. Red flags include: previous reports of difficulty passing a breathing tube, a previous tracheostomy scar, morbid obesity, a full beard, a receding mandible, inability to fully open the mouth, rigidity of the cervical spine, airway tumors or masses, or congenital airway deformities.
  2. Learn the ASA Difficult Algorithm and be prepared to follow it. (asahq.org/…/ASAHQ/…/standards-guidelines/practice-guidelines-for- management-of-the-difficult-airway.pdf‎).
  3. Become skilled with all critical airway skills, particularly mask ventilation, standard laryngoscopy, video laryngoscopy, placement of a laryngeal mask airway (LMA), fiberoptic intubation through an LMA, and awake fiberoptic laryngoscopy.
  4. Read the airway strategy recommended in the Appendix to Richard Jaffe’s Anesthesiologist’s Manual of Surgical Procedures, an approach which utilizes a cascade of the three critical skills of (A)standard laryngoscopy, (B)video laryngoscopy, and (C)fiberoptic intubation through an LMA. For a concise summary of this approach read my column Avoiding Airway Disasters in Anesthesia (http://theanesthesiaconsultant.com/2014/03/14/avoiding-airway-disasters-in-anesthesia).
  5. If you seriously ponder whether awake intubation is indicated, you probably should perform one. You don’t want to wind up with a hypoxic patient, anesthetized and paralyzed, who you can neither intubate nor ventilate.
  6. If you’re concerned about a difficult intubation or a difficult mask ventilation, get help before you begin the case. Enlist a second anesthesia provider to assist you with the induction/intubation.
  7. Take great care when you remove an airway tube on any patient with a difficult airway. Don’t extubate until vital signs are normal, the patient is awake, the patient opens their eyes, and the patient is demonstrating effective spontaneous respirations. An airway that was routine at the beginning of a surgery may be compromised at the end of surgery, due to head and neck edema, airway bleeding, or swollen airway structures, e.g. due to a long anesthetic with a prolonged time in Trendelenburg position.
  8. If you’re a non-anesthesia professional administering conscious sedation, never administer a general anesthetic sedative such as propofol. A combination of narcotic and benzodiazepines can be easily reversed by the antagonists naloxone and flumazenil if oversedation occurs. There is no reversal for propofol. Airway compromise from oversedation due to propofol must be managed by mask ventilation by an airway expert.

In its 1999 report, To Err Is Human:  Building a Safer Health System, the Institute of Medicine recognized anesthesiology as the only medical profession to reduce medical errors and increase patient safety. With the pulse oximeter, end-tidal-CO2 monitor, a myriad of airway devices, and the Difficult Airway Algorithm, the practice of anesthesia in the twenty-first century is safer than ever before. Let’s keep it that way.

Faith, hope, and love. The greatest of these is love.

Airway, breathing, and circulation. The greatest of these is airway. Your patient’s airway.

IS ANESTHESIA A CUSHY SPECIALTY?

THE ANESTHESIA CONSULTANT

Is anesthesia worthy of the House of God‘s assessment that it’s a cushy medical specialty? My answer, after thirty years of anesthesia practice, is … it depends.

Cover image of The House of God

Samuel Shem’s classic novel/satire of medicine, The House of God (published in 1978, more than two million copies sold), follows protagonist Dr. Roy Basch as he struggles through his year as an internal medicine intern. A second physician recommends Basch switch careers to one of six no-patient-contact specialties: Rays, Gas, Path, Derm, Eyes, or Psych. These names translate to radiology, anesthesia, pathology, dermatology, ophthalmology, and psychiatry. These specialties are touted as lower stress choices with superior lifestyles, where time with sick patients is minimized and the physician is more likely to be happy.

Is this true? Is anesthesia worthy of Samuel Shem’s assessment that it’s a cushy specialty?

My answer, after thirty years of anesthesia practice, is … it depends.

Let’s examine each of the six specialties regarding their perceived advantages:

• Radiology involves a career of peering at digital images of X-rays, MRIs, CT scans, or ultrasound studies. Patient contact is minimal. Because many of these tests are ordered in emergency rooms at all hours of the night, on-call radiologists work long hours and endure sleepless nights. As well, the subspecialty of Invasive Radiology has become a hands-on field that requires as much patient contact as most surgical specialties.
• Pathology involves a career of peering through a microscope, running a clinical lab to determine blood and urine chemistry results, or performing autopsies. Most of pathology requires zero contact with living patients. Most pathology work is done in daylight hours, and loss of sleep is unusual.
• Dermatology involves a career of seeing a multitude of patients (think 80 – 100 per day) in a busy clinic practice. Patient volume and patient contact are high. Each clinic visit is brief because only the specific skin lesions in question are fair game for physician-patient interrogation. Hospitalized patients are uncommon, there are few emergencies, and loss of sleep is unusual.
• Ophthalmology involves an office practice of examining the vision and eyes of patients, as well as an operating room practice of performing cataract, retinal, or corneal surgeries. Other than an occasional eye trauma surgery at a late hour, loss of sleep for ophthalmologists is unusual.
• Psychiatry involves an outpatient practice of verbal therapy and/or prescribing oral medications (e.g. antidepressants, anti-anxiety, or attention deficit hyperactivity disorder meds). Inpatient psychiatry is usually limited to patients with severe depression and psychotic diseases. Most emergencies are limited to patients with after-hours suicidal ideation or attempts. Loss of sleep is unusual.
• Anesthesiology involves providing unconsciousness and medical management to patients during all types of surgical interventions. Surgeries occur at all hours of the day and night. Loss of sleep is common, and job stress during select cases can be extreme. Let’s examine lifestyle issues of anesthesia practice in more detail:

An anesthesiologist and his or her awake surgical patient are only together for only 15 minutes prior to induction of anesthesia, during which time they exchange information on medical history and informed consent. This brief duration doesn’t exactly qualify for The House of God’s no-patient-contact list, but anesthesia does qualify as very-little-awake-patient contact. Minimal time with conscious patients appeals to physicians who don’t relish prolonged face-to-face patient interaction.

An image of your anesthesiologist playing tennis or golf and then waltzing into the operating room at leisure to do a simple surgery is mistaken. The presence of an anesthesiologist is imperative for nearly every emergency procedure. All emergency medical care follows the guideline of A-B-C, or Airway-Breathing-Circulation, and anesthesiologists are airway specialists nonpareil. Emergency room attendings and head and neck surgeons have certain airway skills, but no other specialty has the depth of airway expertise that anesthesiologists own. An anesthesiologist provides care for 500–1000 patients per year, and every one of these patients requires acute management of the airway to assure safe oxygenation and breathing.

Trauma surgery, childbirth, acute surgical disease from the emergency room, and organ transplant surgery are as common at night as in the daytime. An on-call anesthesiologist at a busy community hospital may arrive at 6:30 a.m., do seven or eight surgical anesthetics which last until dusk, and then remain in the hospital all night to perform several epidural anesthetics on laboring women, anesthetize an 80-year-old woman for surgery to relieve a bowel obstruction, and replace an endotracheal tube in a struggling patient in the intensive care unit as the sun comes up the following day. An on-call anesthesiologist at a university hospital may arrive at 6:30 a.m. and attend to a complex liver-transplant surgery which lasts 20 hours and concludes at 3 a.m. A cushy specialty? Hardly.

A lifestyle advantage for anesthesiologists is that we can work hard and play hard. It’s possible for an anesthesiologist to take weeks or months off at a time if their employer or anesthesia group approves. There’s no chronic patient care/patient follow up, no clinic overhead, and no clinic employee overhead. For these reasons an anesthesiologist can schedule multiple weeks without work or income more easily than a clinic doctor can. For these reasons it’s also possible for an anesthesiologist to work part time, i.e. two or three days each week. This scheduling flexibility is an excellent lifestyle advantage, and for this reason my answer to whether anesthesia is a cushy specialty is … it depends.

Some anesthesiologists choose to spend their career outside the operating room. Some specialize in pain management and see patients in outpatient pain clinics—selected patients are taken to the operating room non-urgently to receive pain-injection procedures such as epidural steroid injections, nerve blocks, or pain pump insertions. A small number of anesthesiologists run preoperative assessment clinics where they assess the medical status of patients prior to surgery. A small number of anesthesiologists supervise intensive care units and manage critically patients who require ventilators, cardio-active medications, and anesthesia sedation infusions.

I’d like to leave you with one image imprinted in your mind—that of an anesthesiologist toiling over an ill patient at 2 a.m. in a hospital. The patient may have survived a car crash, suffered a ruptured appendix, be delivering twin babies, or be the recipient of a lung transplant. Wherever there’s a sick patient who needs acute supervised unconsciousness, there’s an anesthesiologist present. In words John Steinbeck wrote at the conclusion of The Grapes of Wrath, Tom Joad tells his mother,

“I’ll be all around in the dark – I’ll be everywhere.
Wherever you can look – wherever there’s a fight, so hungry people can eat, I’ll be there.
Wherever there’s a cop beatin’ up a guy, I’ll be there.
I’ll be in the way guys yell when they’re mad.
I’ll be in the way kids laugh when they’re hungry and they know supper’s ready, and when the people are eatin’ the stuff they raise and livin’ in the houses they build – I’ll be there, too.”

This prompts me to pen parallel text regarding my specialty, entitled
Tom Joad the Anesthesiologist:

I’ll be all around in the dark—I’ll be everywhere.
Wherever you can look—wherever there’s a motorcycle accident, a Cesarean section, a heart transplant, I’ll be there.
Wherever there’s a cop dragging a knifed-up gang member into the E.R., I’ll be there.
I’ll be there when the surgeon screams and when the new mother laughs,
When the 100-year-old gets his hernia mended and when the 4-year-old gets his tonsils out—I’ll be there, too.
Ma, it’s just what I do.
It’s what we all do.

THE PERIOPERATIVE SURGICAL HOME HAS EXISTED FOR YEARS

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

The American Society of Anesthesiologists is supporting an expansion of the role of anesthesiologists in the delivery of perioperative care in hospitals. This proposed model is called the Perioperative Surgical Home. The American Society of Anesthesiologists defines the Perioperative Surgical Home as “a patient centered, innovative model of delivering health care during the entire patient surgical/procedural experience; from the time of the decision for surgery until the patient has recovered and returned to the care of his or her Patient Centered Medical Home or primary care provider.”

 

It’s a sound idea, and it resembles a model that’s existed for decades outside the hospital. In an outpatient surgery center the Perioperative Surgical Home concept is carried out by an anesthesiologist who is the Medical Director. I can speak to this, as I’ve been the Medical Director at a busy surgery center only minutes from Stanford University in downtown Palo Alto, for the past 12 years.

A surgery center Medical Director is responsible for:

  • All preoperative matters, including preoperative medical assessment of patients, scheduling of block times, surgical cases, anesthesia assignments, and creation of protocols,
  • All intraoperative matters, including quality issues, efficiency and turnover of cases, and the economics of running a profitable set of operating rooms, and
  • All postoperative matters, including overseeing Post Anesthesia Care Unit (PACU) nursing care, post anesthesia medical decisions, and supervision of post-discharge follow up with patients.

All medical problems including complications, hospital transfers, and patient complaints, are routed through the anesthesiologist Medical Director.

A key difference between a surgery center and a hospital is scale. A busy hospital has dozens of operating rooms, hundreds of surgeries per day, and hundreds of inpatient beds. No one Medical Director can oversee all of this every day—it takes a team. At Stanford University Medical Center the anesthesia department is known as the Department of Anesthesia, Perioperative and Pain Medicine. The word “Perioperative” is appropriate, because anesthesia practice involves medical care before, during, and after surgery. A team of anesthesiologists is uniquely qualified to oversee preoperative assessment, intraoperative management, and post-operative pain control and medical care in the hospital setting, just as the solitary Medical Director does in a surgery center setting.

A second key difference between a surgery center and a hospital is that medical care is more complex in a hospital. Patients are sicker, invasive surgeries disturb physiology to a greater degree, and patients stay overnight after surgery, often with significant pain control or intensive care requirements. Again, a team of physicians from a Department of Anesthesia, Perioperative and Pain Medicine is best suited to supervise management of these problems.

The greatest hurdle to instituting the Perioperative Surgical Home model is pre-existing economic reality. In a hospital, other departments such as surgery, internal medicine, radiology, cardiology, pulmonology, and nursing are intimately involved in the perioperative management of surgery patients. Each of these departments has staff, a budget, income, and incentives related to maintaining their current role. Surgeons intake patients through their preoperative clinics, and may regard themselves as captains of the ship for all medical care on their own patients. Internal medicine doctors are called on for preoperative medical clearance on patients, and thus compete with anesthesia preoperative clinics. The internal medicine department includes hospitalists, inpatient doctors who may be involved in the post-operative management of inpatients. Invasive radiologists perform multiple non-invasive surgical procedures. Like their surgical colleagues, they may see themselves as decision makers for all medical care on their own patients. Cardiologists manage coronary care units and intensive care units in some hospitals, and may feel threatened by anesthesiologists intent on taking over their territory. Pulmonologists manage coronary care units and intensive care units in some hospitals, and may feel threatened by anesthesiologists intent on taking over their territory. Nurses are involved in all phases of perioperative care. If the chain of command among physicians changes, nurses must be willing partners of and participants with such change.

Why has the anesthesiology leadership role of a Medical Director evolved naturally at surgery centers while the Perioperative Surgical Home idea has to be sold to hospitals? At surgery centers the competing financial incentives of surgeons, internal medicine doctors, radiologists, pulmonologists, cardiologists, and nurses are minimal. In a freestanding surgery center, surgeons want to be able to depart for their offices following procedures, and welcome the skills that anesthesiologists bring to managing any medical complications that arise. Internal medicine doctors have no significant on-site role in surgery centers, although they are helpful office consultants for the anesthesiologist/Medical Director in assembling preoperative clearance for outpatients. Radiologists have no significant on-site role at most surgery centers—if they do perform invasive radiology procedures on outpatients, they too welcome the skills that anesthesiologists bring to managing medical complications that arise. Because there are no intensive care units at a surgery center, there is no role for pulmonary or cardiology specialists. Nursing leadership at a surgery center works hand-in-hand with the Medical Director to assure optimal nursing care of all patients.

Hospital administrators anticipate penetration of the Accountable Care Organization (ACO) model for payment of medical care by insurers. In the ACO model, a medical center receives a predetermined bundled payment for each surgical procedure. The hospital and all specialties caring for that patient negotiate what percentage of that ACO payment each will receive. A Perioperative Surgical Home may or may not simplify this task. You can bet anesthesiologists see the Perioperative Surgical Home as a means to increase their piece of the pie. Ideally the Perioperative Surgical Home will be a means to streamline medical care, decrease costs, and increase profit for the hospital and all departments. Anesthesiologists are rightly concerned that if they don’t take the lead in this process, some other specialty will.

Establishing the Perioperative Surgical Home is an excellent opportunity for anesthesiologists to facilitate patient care in multiple aspects of hospital medicine. To make this dream a reality across multiple medical centers, anesthesiology leadership must demonstrate excellent public relations skills to convince administrators and chairpeople of the multiple other specialties. I expect data on outcomes improvement or cost-control to be slow and inadequate to proactively provoke this change. It will take significant lobbying, convincing, and promoting. Change will require a leap of faith for a hospital, and such change will only be accomplished by anesthesia leadership that captures the confidence of the hospital CEO and the chairs of multiple other departments.

I’m impressed by the adoption of the Perioperative Surgical Home at the University of California at Irvine. I’ve listened to Zev Kain, MD, Professor and Chairman of the Department of Anesthesia and Perioperative Medicine lecture, and I’ve met him personally. He’s the prototype of the charismatic, intelligent, and convincing physician needed to convince others that the Perioperative Surgical Home is the model of the future.(http://www.anesthesiology.uci.edu/clinical_surgicalhome.shtml)

I expect the transition to the Perioperative Surgical Home to occur more easily in university or HMO hospitals than in community hospitals. It will be easier for academic or HMO chairmen to assign new roles to salaried physicians than it will be for community hospitals to control the behavior of multiple private physicians.

Anesthesiologists were leaders in improving perioperative safety by the discovery and adoption of pulse oximetry and end-tidal carbon dioxide monitoring. Can anesthesiologists lead the way again by championing the adoption of Perioperative Surgical Home on a wide scale? Time will tell. Is the Perioperative Surgical Home an optimal way to take care of surgical patients before, during, and after surgeries? I believe it is, just as the Medical Director is a successful model of how an anesthesiologist can optimally lead an outpatient surgery center. Those lobbying for the Perioperative Surgical Home would be wise to examine the successful role of anesthesiologist Medical Directors who’ve led outpatient surgery centers for years. The stakes are high. As intraoperative care becomes safer and the role of nurse anesthesia in the United States threatens to expand, it’s imperative that physician anesthesiologists assert their expertise outside the operating room.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

HOW LONG WILL IT TAKE ME TO WAKE UP FROM GENERAL ANESTHESIA?

THE ANESTHESIA CONSULTANT

One of the most frequent questions I hear from patients before surgery is, “How long will it take me to wake up from general anesthesia?”

 

The answer is, “It depends.”

Your wake up from general anesthesia depends on:

  1. What drugs the anesthesia provider uses
  2. How long your surgery lasts
  3. How healthy, how old, and how slender you are
  4. What type of surgery you are having
  5. The skill level of your anesthesia provider

In best circumstances you’ll be awake and talking within 5 to 10 minutes from the time your anesthesia provider turns off the anesthetic. Let’s look at each of the five factors above regarding your wake up from general anesthesia depends on:.

  1. YOUR WAKE UP FROM ANESTHESIA DEPENDS ON WHAT DRUGS THE ANESTHETIST USES. The effects of modern anesthetic drugs wear off fast.
  • The most common intravenous anesthetic hypnotic drug is propofol. Propofol levels in your blood drop quickly after administration of the drug is terminated, resulting in rapid awakening.
  • The most common inhaled anesthetic drugs are sevoflurane, desflurane, and nitrous oxide. Each of these gases are exhaled from the body quickly after their administration is terminated, resulting in rapid awakening.
  • The most commonly used intravenous narcotic is fentanyl. Fentanyl levels in your blood drop quickly after administration of the drug is terminated, resulting in rapid awakening.
  • The most commonly used intravenous anti-anxiety drug is midazolam (Versed). Midazolam levels in your blood drop quickly after administration of the drug is terminated, resulting in rapid awakening.
  1. YOUR WAKE UP FROM ANESTHESIA DEPENDS ON HOW LONG YOUR SURGERY LASTS
  • The shorter your surgery lasts, the less injectable and inhaled drugs you will receive.
  • Lower doses and shorter exposure times to anesthetic drugs lead to a faster wake up time.
  1. YOUR WAKE UP FROM ANESTHESIA DEPENDS ON HOW HEALTHY, HOW OLD, AND HOW SLENDER YOU ARE
  • Healthy patients with fit hearts, lungs, and brains wake up sooner
  • Young patients wake up quicker than geriatric patients
  • Slender patients wake up quicker than very obese patients
  1. YOUR WAKE UP FROM ANESTHESIA DEPENDS ON WHAT TYPE OF SURGERY YOU ARE HAVING
  • A minor surgery with minimal post-operative pain, such a hammertoe repair or a tendon repair on your thumb, will lead to a faster wake up.
  • A complex surgery such as an open-heart procedure or a liver transplant will lead to a slower wake up.
  1. YOUR WAKE UP FROM ANESTHESIA DEPENDS ON THE SKILL LEVEL OF YOUR ANESTHETIST
  • Like any profession, the longer the duration of time a practitioner has rehearsed his or her art, the better they will perform. An experienced pilot is likely to perform smoother landings of his aircraft than a novice. An experienced anesthesiologist is likely to wake up his or her patients more quickly than a novice.
  • There are multiple possible recipes or techniques for an anesthetic plan for any given surgery. An advantageous recipe may include local anesthesia into the surgical site or a regional anesthetic block to minimize post-operative pain, rather than administering higher doses of intravenous narcotics or sedatives which can prolong wake up times. Experienced anesthesia providers develop reliable time-tested recipes for rapid wake ups.
  • Although I can’t site any data, I believe the additional training and experience of a board-certified anesthesiologist physician is an advantage over the training and experience of a certified nurse anesthetist.

YOUR WAKE UP FROM ANESTHESIA: EXAMPLE TIMELINE FOR A MORNING SURGERY

Let’s say you’re scheduled to have your gall bladder removed at 7:30 a.m. tomorrow morning. This would be a typical timeline for your day:

6:00            You arrive at the operating room suite. You check in with front desk and nursing staff.

7:00             You meet your anesthesiologist or nurse anesthetist. Your anesthesia provider reviews your chart, examines your airway, heart, and lungs, and explains the anesthetic plan and options to you. After you consent, he or she starts an intravenous line in your arm.

7:15             Your anesthesia provider administers intravenous midazolam (Versed) into your IV, and you become more relaxed and sedated within one minute. Your anesthesia provider wheels your gurney into the operating room, and you move yourself from the gurney to the operating room table. Because of the amnestic effect of the midazolam, you probably will not remember any of this.

7:30             Your anesthesia provider induces general anesthesia by injecting intravenous propofol and fentanyl, places a breathing tube into your windpipe, and administers inhaled sevoflurane and intravenous propofol to keep you asleep.

7:40            Your anesthesia provider, your surgeon, and the nurse move your body into optimal position on the operating room table. The nurse preps your skin with antiseptic, and the scrub tech frames your abdomen with sterile paper drapes. The surgeons wash their hands and don sterile gowns and gloves. The nurses prepare the video equipment so the surgeon can see inside your abdomen with a laparoscope during surgery.

8:00            The surgery begins.

8:45             The surgery ends. Your anesthesia provider turns off the anesthetics sevoflurane and propofol.

8:55             You open your eyes, and your anesthesia provider removes the breathing tube from your windpipe.

9:05             Your anesthesia provider transports you to the Post Anesthesia Care Unit (PACU) on the original gurney you started on.

9:10            Your anesthesia provider explains your history to the PACU nurse, who will care for you for the next hour or two. The anesthesia provider then returns to the pre-operative area to meet their next patient. Your anesthesia provider is still responsible for your orders and your medical care until you leave the PACU. He or she is available on cell phone or beeper at all times. No family members are allowed in the PACU.

10:40            You are discharged from the PACU to your inpatient room, or to home if you are fit enough to leave the hospital or surgery center.

YOUR WAKE UP FROM ANESTHESIA . . . TO REVIEW:

  1. Even though the surgery only lasted 45 minutes, you were in the operating room for one hour and 35 minutes.
  2. It took you 10 minutes to awaken, from 8:45 to 8:55.
  3. Even though you were awake and talking at 8:55, you were unlikely to remember anything from that time.
  4. You probably had no memory of the time from the midazolam administration at 7:15 until after you’d reached in the PACU, when your consciousness level returned toward normal.

HOW TO PREPARE TO SAFELY INDUCE GENERAL ANESTHESIA IN TWO MINUTES

THE ANESTHESIA CONSULTANT

How do you prepare to induce general anesthesia in two minutes? You’re called to induce anesthesia for a patient being rushed to the operating room for emergency surgery. You arrive at the operating room only minutes before the patient is scheduled to arrive. I recommend you use the mnemonic M-A-I-D-S as a checklist to prepare yourself and your equipment.

 

 

M stands for MACHINE and MONITORS. Check out your anesthesia machine first. Determine the oxygen sources are intact, and that the circle system is airtight when the pop-off valve is closed and your thumb occludes the patient end of the circle. Make sure the anesthesia vaporizer liquid anesthetic level is adequate. Check out your routine monitors next. Determine that the oximeter, end-tidal gas monitor, blood pressure cuff, and EKG monitors are turned on and ready.

A stands for AIRWAY equipment. Make sure an appropriate-sized anesthesia mask is attached to the circle system. Determine that your laryngoscope light is in working order. Prepare an appropriate sized endotracheal tube with a stylet inside. Have appropriate-sized oral airways and a laryngeal mask airway (LMA) available in case the airway is difficult. Make sure you have a stethoscope so you can examine the patient’s heart and lungs.

I stands for IV. Have an IV line prepared, and have the equipment to start an IV ready if the patient presents without an intravenous line acceptable for induction of anesthesia.

D stands for DRUGS. At the minimum you’ll need an induction agent (e.g. propofol or etomidate) and a muscle relaxant (succinylcholine or rocuronium), each loaded into a syringe. You’ll need narcotics and perhaps a dose of midazolam as well. Cardiovascular drugs to raise or lower blood pressure will be available in your drug drawer or Pyxis machine.

S stands for SUCTION. Never start an anesthetic without a working suction catheter at hand. You must be ready to suction vomit or blood out of the airway acutely if the need arises.

For pediatric patients the M-A-I-D-S mnemonic is followed, but in addition the size of your anesthesia equipment must be tailored to the age of the patient. Let’s say your patient is 4 years old. For M=MACHINE, you may need a smaller volume ventilation bag and hoses. For M=MONITORS, you’ll need a smaller blood pressure cuff, a smaller oximeter probe, and a precordial stethoscope if you use one. For A=AIRWAY, you’ll need smaller endotracheal tubes and airways. For I=IV, you’ll need smaller IV catheters and IV bags.

As a last-second check before a pediatric anesthetic, I recommend you pull out each drawer on your anesthesia machine, and then on your anesthesia cart, one at a time. Scan the contents of each drawer to ascertain whether you need any of the equipment there before you begin your anesthetic.

If you have any suspicion that the patient’s airway is going to be difficult, I recommend you ask to have a video laryngoscope and a fiberoptic laryngoscope brought into the operating room.

Once the patient arrives, utilize time to assess the situation as any doctor does. Take a quick history and perform a pertinent exam of the vital signs, airway, heart, lungs, and also a brief neuro check. Assist in positioning the patient on the operating room table, supervise the placement of routine monitors, and begin preoxygenating the patient. Induce anesthesia when you are ready.

Never be coerced to rush an anesthesia induction if your anesthesia setup or the patient’s physiology are not optimized. And always utilize the mnemonic M-A-I-D-S as an anesthesia checklist to confirm that your equipment is ready.

THE EBOLA VIRUS, ANESTHESIA, AND SURGERY

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

A patient infected with the Ebola virus is admitted to your hospital’s intensive care unit. You are called to intubate the Ebola patient for respiratory failure. What do you do?

ebola medical ICU team

Discussion: The first patients infected with Ebola virus entered the United States in 2014. American physicians are inexperienced with caring for patients with this disease. Because of physicians’ commitments to care for the sick and injured, individual doctors will have an obligation to provide urgent medical care during disasters. This will include Ebola patients.

The American Society of Anesthesiologists (ASA) published Recommendations From the ASA Ebola Workgroup on October 24, 2014.

Select information in my column today is abstracted, copied, and summarized from this detailed publication. Let’s begin by reviewing some facts about the disease.

Ebola is an enveloped, single-stranded RNA virus, one of several hemorrhagic viral families first identified in a 1976 outbreak near the Ebola River in the Democratic Republic of the Congo.

Transmission of Ebola is via direct contact, droplet contact, or possibly contact with short-range aerosols. The virus is carried in the blood and body fluids of an infected patient (i.e. urine, feces, saliva, vomit, breast milk, sweat, and semen). Risky exposures include exposure of your broken skin or mucous membranes to a percutaneous contaminated sharps injury, to contaminated fomites (a fomite is an inanimate object or substance, such as clothing, furniture, or soap, that is capable of transmitting infectious organisms from one individual to another), or to infected animals.

The case definition for Ebola includes fever, an epidemiologic risk factor including travel to West Africa (or exposure to someone who has recently traveled there), and one or more of these symptoms: severe headache, muscle pain, vomiting, diarrhea, stomach pain, unexplained bleeding or bruising (appearing anywhere from 2 to 21 days after exposure), a maculopapular rash, disseminated intravascular coagulation, or multi-organ failure.

Although coughing and sneezing are not common symptoms of Ebola, if a symptomatic patient with Ebola coughs or sneezes on someone and saliva or mucus come into contact with that person’s eyes, nose or mouth, these fluids may transmit the disease. Ebola can survive outside the body on dry surfaces such as doorknobs and countertops for several hours. Virus in body fluids (such as blood) can survive up to several days at room temperature.

The treatment for Ebola is symptomatic management of volume status using blood bank products as indicated, and management of electrolytes, oxygenation, and hemodynamics.

Healthcare professionals must wear protective outfits when treating Ebola patients. Routine Personal Protective Equipment (PPE) must include the following (when properly garbed, there should be no exposed skin):

  1. Surgical hood to ensure complete coverage of head and neck,
  2. Single-use face shield (goggles are no longer recommended due to issues with fogging and difficulty cleaning),
  3. N95 mask,
  4. An impermeable gown (with sleeves) that extends at least to mid-calf or coverall without a one-piece integrated hood (consideration should be given to wearing a protective coverall layer under the impermeable gown, which allows for layered protection and progressively less contaminated layers when doffing),
  5. Double gloves (i.e., disposable nitrile gloves with a cuff that extends beyond the cuff of the gown), the cuff of the first pair is worn under the gown and the second cuff should be over the gown, impermeable shoe covers that go to at least mid-calf or leg covers (there must be overlap of the impermeable layers),
  6. Impermeable and washable shoes,
  7. An apron that is waterproof and covers the torso to the level of the mid-calf should be used if Ebola patients have vomiting or diarrhea.

Enhanced Precaution PPE is advised for aerosol generating procedures such as intubation, extubation, bronchoscopy, airway suction, and surgery. This is the recommended level of PPE for anesthesiologists. Enhanced Precaution PPE includes:

  1. Personal Air-Purifying Respirator (PAPR) with full face piece mask,
  2. A disposable hood that extends to the shoulders and is compatible with the selected PAPR,
  3. A coverall without one-piece hood,
  4. Triple gloves (i.e., disposable nitrile with a cuff that extends beyond the cuff of the gown), the cuff of the first pair is worn under the gown and the second cuff should be over the gown and taped, and a third pair of disposable extended cuff nitrile gloves,
  5. Impermeable and washable shoes,
  6. Impermeable shoe covers, and
  7. Duct tape over all seams.

PPE donning (i.e. dressing in PPE outfit) must be performed in the proper order and monitored by a trained observer using a donning checklist. There should be separate designated areas for storage and donning of PPE (an adjacent patient care area), one-way movement to the patient’s room, and an exit to a separate room or anteroom for doffing procedures and disposal.

Doffing (i.e. PPE removal) is a high-risk process that requires a structured procedure, a trained observer (also in PPE), and a designated removal area. Doffing needs to be a slow and deliberate process and must be performed in the correct sequence using a doffing checklist.

Let’s return to our original question. What about that stat intubation you were called to perform in the ICU?

Stat intubations are not to be attempted on Ebola patients by anesthesiologists until the physician has properly donned the Enhanced Precaution PPE outfit. This necessitates significant time. Full Enhanced Precaution PPE precautions are mandated regardless of an emergency status or acute deterioration in patient status. Fiberoptic bronchoscopes are not recommended as aerosolization will occur and adequate cleaning is difficult. All equipment brought into the patient’s room must remain there and will be unusable for an indefinite period of time. Due to the extended time necessary to properly don and doff Enhanced Precaution PPE, an intubation of an Ebola patient could potentially take ninety minutes or longer when accounting for proper donning and doffing procedures.

What about performing surgery and anesthesia on Ebola patients? Patients with severe active disease would not likely tolerate an operation due to the severity of their disease. Any decision to operate should weigh all risks and benefits, specifically the risk of death from the current severity of the Ebola disease, the risk of death from their surgical disease, and the risk of exposure to the operating room team against the likelihood of potential benefit of emergency surgery.

Every effort should be given to keeping the patient in their own isolation room, and moving surgical and anesthetic equipment to the bedside. If possible, all procedures should be performed in the patient’s room.  Every effort should be given to keeping the patient in their own isolation room and moving surgical and anesthetic equipment to the bedside.

If it’s not feasible to perform the procedure or surgery in the intensive care unit room, an operating room should be designated for the patient. Preferably, this operating room should be away from traffic flow, have an anteroom, and not be connected to a clean core.

Transportation to and from the operating room hallways near the designated operating room should be blocked off.  Adjacent operating rooms will be closed. Traffic flow must be limited to only essential personnel involved with the case. PPE must be donned prior to entering the patient’s room.

Recovery from anesthesia will occur in the operating room or the patient’s hospital room, and not in the Post Anesthesia Care Unit (PACU).

These are the recommendations regarding operating room anesthesia set-up:

  1. Drawers of the anesthesia machine should be emptied except for the bare minimum of supplies.
  2. All additional items from atop the machine removed.
  3. The drawers should not be accessed unless absolutely necessary.
  4. All paperwork/laminated protocols and non-essential items must be removed from the machine.
  5. The anesthesia cart should be removed from the room and will not be directly accessible once the patient enters.
  6. An isolation cart (stainless steel or other easily cleanable table) should be stocked with all anticipated medications, emergency medications, syringes, needles, I.V. fluids (multiple), I.V. supplies, arterial line supplies, tubing, suction catheters, NG tubes, endotracheal tubes of appropriate size, additional ECG electrodes, gauze, chlorhexidine or alcohol pads, saline flushes, an extra BP cuff, a sharps container, additional gloves, and any additional equipment and supplies which the anesthesia attending for the cases requests.

Once the patient enters the operating room, absolutely no entry or exit from the operating room will occur without following PPE protocols. As such, bathroom and personal needs should be attended to prior to transporting the patient.

These are recommendations from The American Society of Anesthesiologists Ebola Workgroup. American physicians hope the number of Ebola cases in the United States will approach zero. As anesthesiologists we hope we’ll never be called to intubate or perform anesthesia on a patient infected with Ebola, but we understand our commitment to care for the sick and injured, and we understand that we have an obligation to provide urgent medical care during disasters.

Every hospital in America is in the process of understanding and implementing the above procedures regarding the isolation and protection of healthcare providers from the Ebola virus. If an Ebola patient is admitted to your hospital, I refer you to the Association for Biosafety and Biosecurity.

TEN REASONS NURSE ANESTHETISTS (CRNAs) WILL BE A MAJOR FACTOR IN ANESTHESIA CARE IN THE 21ST CENTURY

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

 

My debut novel, The Doctor and Mr. Dylan features a nurse anesthetist in the starring role of Mr. Dylan. Nurse anesthetists have provided anesthesia care in the United States for nearly 150 years, and CRNs will be a major factor in the future.

41wlRoWITkL

In the beginning, anesthesia care for surgical patients was often provided by trained nurses under the supervision of surgeons, until the establishment of anesthesiology as a medical specialty in the U.S. in the 20th century.

Here are 10 reasons why certified registered nurse anesthetists (CRNAs) will be a major factor in anesthesia care in the 21st century:

1. Rural America is dependent on CRNAs to staff surgery in small towns underserved by MD anesthesiologists. CRNAs are involved in providing anesthesia services to about one-quarter of the American population that resides in rural and frontier areas of this country. Despite a significant rise in the number of anesthesiologists in recent years, there is no evidence that they are attracted to practice in rural areas.
2. Obamacare will increase the demand for mid-level healthcare providers, e.g. nurse practitioners, physician assistants, and nurse anesthetists. These mid-level providers are perceived as a cheaper alternative to MD health care.
3. Seventeen states have opted out of the requirement for physician supervision of CRNA anesthetics. These states are Iowa, Nebraska, Idaho, Minnesota, New Hampshire, New Mexico, Kansas, North Dakota, Washington, Alaska, Oregon, Montana, South Dakota, Wisconsin, California, Colorado, and Kentucky. In these states, it’s legal for a CRNA to give an anesthetic without a supervising anesthesiologist or surgeon.
4. For cost-saving reasons, hospital administrators will consider the lower hourly rate charged by CRNAs to be a saving over MD anesthesia care rendered by anesthesiologists alone.
5. Future trends such as the American Society of Anesthesiologists’ Perioperative Surgical Home or bundled payments to Accountable Care Organizations will seek out the cheapest way to manage anesthetic populations. A likely economic model for a healthy patient population is the anesthesia care team, e.g. a 4:1 ratio of four CRNAs supervised by one MD anesthesiologist. This model can be used to staff four simultaneous surgeries on four healthy patients having simple surgical procedures. More complex procedures such as open-heart surgery, brain surgery, major vascular surgery, or emergency surgery will be best served by MD anesthesia care. Extremes of age (e.g. neonates or very old patients) and patients with significant medical comorbidities will be best served by MD anesthesia care.
6. Certain regions of the United States, particularly the South and the Midwest, are already entrenched with anesthesia care team models of 3:1 or 4:1 CRNA:MD staffing because of anesthesiologist preference. An MD anesthesiologist’s income can be augmented by supervising three or four operating rooms with multiple CRNAs simultaneously. These physicians will have little desire to rid themselves of nurse anesthetists and to personally do only one case at a time by themselves.
7. The American Association of Nurse Anesthetists (AANA) presents a strong, well-funded lobby which promotes the continuing and increasing role of CRNAs in medical care in the United States.
8. The educational cost for a registered nurse to become a CRNA is significantly less than the cost of training a board-certified MD anesthesiologist. The median cost of a public CRNA program is $40,195 and the median cost of a private program is $60,941, with an overall median of $51,720.
9. A registered nurse can significantly increase their income by becoming a CRNA. A registered nurse with one year of intensive care unit or post-anesthesia care unit experience can become a CRNA with 2-3 years of CRNA schooling. The average yearly salary of a CRNA in America in 2011 was $156,642.
10. The increasing starring role of CRNAs in American fiction ☺. (See The Doctor and Mr. Dylan, below)

After perusing this list one might ask, are CRNAs and anesthesiologists equals?
No, they are not. Anesthesiologists are doctors, and their training of four years of medical school followed by a minimum of four years of anesthesia residency makes them specialists in all aspects of surgical medicine.

The American Society of Anesthesiologists’ STATEMENT ON THE ANESTHESIA CARE TEAM states “Anesthesiology is the practice of medicine including, but not limited to, preoperative patient evaluation, anesthetic planning, intraoperative and postoperative care and the management of systems and personnel that support these activities. In addition, anesthesiology includes perioperative consultation, the management of coexisting disease, the prevention and management of untoward perioperative patient conditions, the treatment of acute and chronic pain, and the practice of critical care medicine. This care is personally provided by or directed by the anesthesiologist.” (Approved by the ASA House of Delegates on October 26, 1982, and last amended on October 16, 2013)

Doctor J H Silber’s landmark study from the University of Pennsylvania documented that both 30-day mortality and failure-to-rescue rates were lower when anesthesia care was supervised by anesthesiologists, as opposed to anesthesia care by unsupervised nurse anesthetists. This study has been widely discussed. The CRNA community dismissed the conclusions, citing that the Silber study was a retrospective study. In a Letter to the Editor published in Anesthesiology, Dr. Bruce Kleinman wrote regarding the Silber data, “this study could not and does not address the key issue: can CRNAs practice independently?”

I’m not a fan of CRNAs working alone without physician supervision. In both my expert witness practice and in the expert witness practice of my anesthesia colleagues, we find multiple adverse outcomes related to acute anesthetic care carried out by non-anesthesiologists.

CRNAs will play a significant role in American healthcare in the future. That significant role will be best played with an MD anesthesiologist at their right hand.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

WHAT ONE QUESTION SHOULD YOU ASK TO DETERMINE IF A PATIENT IS ACUTELY ILL?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.
emailrjnov@yahoo.com
THE ANESTHESIA CONSULTANT

What one question should you ask to determine whether a patient has a serious medical problem? What one question must you ask to determine whether urgent intervention is required?

Imagine this scenario: You’re an anesthesiologist giving anesthesia care in the operating room to your second patient of the day. The Post Anesthesia Care Unit (PACU) nurse calls you regarding your first patient who is in the PACU following appendectomy. The nurse says, “Your patient Mr. Jones is still nauseated and very sleepy. I’ve medicated him with ondansetron and metoclopramide as ordered, but he’s still nauseated and sleepy.”

That one question would be: “What are his vital signs?”(This is a bit of a trick question, since you are asking not one question, but four or five. It’s as if you’re down to your last request from the Genie from Aladdin’s lamp, and you’re wishing for more wishes. As Robin Williams’ Genie character said in Disney’s Aladdin, “Three wishes, to be exact. And ixnay on the wishing for more wishes. That’s all. Three. Uno, dos, tres. No substitutions, exchanges or refunds.” )

The traditional four vital signs are the blood pressure, heart rate, respiratory rate, and temperature. For anesthesiologists, surgeons, emergency room physicians, and ICU doctors, the fifth vital sign is the oxygen saturation or O2 sat. Some publications tout the pain score (on a 1-10 scale) as a fifth vital sign. While I subscribe to the pain score’s importance, it’s of less value in most acute care situations than the O2 saturation.

Let’s return to the patient scenario. You ask the nurse, “What are the patient’s vital signs?”

The nurse answers, “His heart rate is 48, his blood pressure is 88/55, his O2 sat is 100, and his respiratory rate is 16.”

You answer, “His heart rate is too low and so is his blood pressure. Let’s give him 0.5 mg atropine IV now.”

Five minutes later the nurse calls back. The heart rate increased to 72 and the blood pressure is 110/77. The patient’s symptoms resolved as the vital signs normalized.

Let’s look at a second scenario. You drop off a 48-year-old hysterectomy patient in the PACU. The patient is awake, and her initial vital signs are BP 120/64, pulse 100, respirations 18, and O2 saturation 99%. You return to the operating room to initiate care for your next patient for a laparoscopy. Thirty minutes later, the PACU nurse calls you to report your first patient has increasing abdominal discomfort. Her repeat vital signs are: BP 110/80, pulse 130, respirations 26, and O2 saturation 99%. You’re concerned an intra-abdominal complication is brewing. Five minutes later, the nurse reports a third set of vitals. The patient’s heart rate continues to rise to 140. Her blood pressure is now 82/40, her respirations are 30, and her skin has become cold and moist to the touch. She’s unable to speak coherently and is losing consciousness. You can not leave the patient you are anesthetizing, but you call a fellow anesthesiologist to evaluate the patient in person, and prepare her for emergent re-operation.

The patient’s initial vital signs were stable, but the downward trend of her vital signs were a harbinger of the serious complication. Eventually the symptoms of abdominal pain and decreasing consciousness appeared, and confirmed the diagnosis of intra-abdominal hemorrhage and impending shock. The increased heart rate, decreased blood pressure, and increased respiratory rate were red flags early on.

Abnormal vital signs can indicate that a patient is acutely ill. Equally important to the value of each vital sign is the temporal trend in the vital signs. A vital sign trend increasing or decreasing from the normal range can validate that the patient is becoming acutely ill.

You may be thinking, why is Dr. Novak telling me vital signs are important? Everybody know vital signs are, well … vital.

My message to you is to seek out the vital signs, all of them, as essential clues in all patients.

As anesthesiologists, we spend our entire intraoperative clinical career staring at a patient’s vital signs on a video screen. When the blood pressure goes up, we act. When the blood pressure goes down, we act. When the heart rate goes up, we act, and when the heart rate goes down, we act. When oxygen saturation trends downward, we act. Because most intraoperative patients are unconscious, the patient’s verbal history—the traditional clues regarding acute illness—are unavailable. We can not ask our patient questions to determine whether vital sign changes are associated with symptoms of chest pain, shortness of breath, or neurologic deficits. We’re accustomed to treating patients by normalizing their vital signs.

Other healthcare providers lack this perspective. Nurses and non-acute-care physicians such as family practitioners and internists can fill a patient’s history chock full of other details so thick that the vital signs are buried. The five or six vital sign numbers are often obscured in pages of text. Most physician and nursing notes in an electronic medical record (EMR) are lengthy, and are many are copied and pasted from previous encounters. Each patient interview is a quiz bowl of medical history answers. The five or six vital sign numbers are a needle in the haystack of a modern medical history. The EMR in a clinic or a hospital can serve to worsen this plight, as vital signs are recorded by nurses and entered into nursing documents on the computer, and treating physicians may have to dig to find the correct page that lists vital signs. One possible benefit of an EMR is a proposed safety system that requires, for any abnormal vital sign entered into the computer, the nurse to document they have verbally informed a physician of that abnormal value. This system would assure that abnormal values are never ignored, and that an MD will assess whether further diagnostic or therapeutic steps need to be taken.

Ferret out the vital signs. In my career as a clinical anesthesiologist and anesthesia expert witness, I can’t recall one significant complication that wasn’t foretold by an increased or decreased heart rate, blood pressure, respiratory rate, or temperature, a decreased O2 saturation, or an increased pain score.

Keep your eye on the vitals, and keep your patients out of trouble.

Bang-Up Debut Novel, November 16, 2014

By Norm Goldman “Publisher & Editor of Bookpleasures”

This part legal and medical thriller is structured with a mixed bag of situations involving relationships, jealousy, evil, lies, courtroom drama, operating room mishaps as well as moments that engender conflicting and unexpected outcomes. Noteworthy is that as the suspense builds readers will become eager to uncover the truth involving a mishap concerning Nico and a surgical procedure that has unanticipated ramifications.

This is a bang-up debut from a writer who understands timing and is able to deliver hairpin turns, particularly involving the courtroom drama,that you would expect from a book of this genre.

“The Doctor & Mr. Dylan” by Rick Novak

Dr. Nico Antone doesn’t hide the fact he hates his wife, but he says he didn’t kill her during an operation. The authorities think otherwise and his trial is the riveting suspense in this novel that is part medical thriller, part legal thriller, part exploration of family relationships.

Nico is an anesthesiologist (as is the author) who leaves his wife, their plush life in California and his job at Stanford to move to his hometown of Hibbing so their son, Johnny, has a better chance of getting into a prestigious college. Johnny hates the idea of moving to a small, cold town, but he’s popular from the first day in school. Nico doesn’t do so well. He’s envied by Bobby, an anesthetist who’s jealous of the better-educated Nico. But it’s hard to take Bobby seriously, since he thinks he’s the young Bob Dylan and lives in the house where Bobby Zimmerman grew up. To complicate matters, Nico is attracted to the mother of the young woman his son is dating. When the two teens get in trouble, Nico’s furious, rich wife comes to Minnesota and needs an emergency operation that puts her on Nico’s operating table.

Novak grew up in Hibbing, where he worked in the iron ore mines and played on the U.S. Junior Men’s Curling championship teams of 1974 and ’75. After graduating from Carleton College, he earned a medical degree at the University of Chicago and spent 30-plus years at Stanford Hospital, where he was an associate professor of anesthesia and Deputy Chief of the Anesthesia Department. His courtroom scenes are based on his experiences as an expert witness.

The Physician’s Late-Night Reading List

Two Pritzker alums pen captivating tales

By Brooke E. O’Neill, University of Chicago Pritzker School of Medicine, editir, Medicine on the Midway Magazine

For most physicians, writing — patient notes, case histories, perhaps journal articles — is part of the job. But for anesthesiologist-novelist Rick Novak, MD’80, and neurosurgeon-memoirist Moris Senegor, MD’82, it’s a second career that consumes early morning hours long before they step into the OR.

Fans of John Grisham will find a kindred spirit in Novak, whose fast-paced medical thriller, The Doctor & Mr. Dylan transports readers to rural Northern Minnesota, where an accomplished physician and a deranged anesthetist who thinks he’s rock legend Bob Dylan see their worlds collide in the most unexpected ways.

Delivering real-life twists and turns — and a love letter to the Bay Area — is Senegor’s Dogmeat: A Memoir of Love and Neurosurgery in San Francisco (Xlibris, 2014), a coming-of-age tale chronicling the author’s away rotation with renowned neurosurgeon Charles Wilson, MD, at the University of California, San Francisco. Brutally honest, it spares no details of a time Senegor, who also served as a resident under the University of Chicago’s famed neurosurgery chair Sean Mullan, MD, describes as “one of the biggest failures of my life.”

One a vividly imagined nail-biter, the other an intimate peek into the surgical suite, both books deliver an ample dose of intensity and drama.

“I thought it was a novel way of killing someone,” said Rick Novak, Deputy Chief of Anesthesiology at Stanford University, describing the imagined hospital death that was the genesis of his dark thriller The Doctor & Mr. Dylan. A huge Bob Dylan fan — the rock icon was born in Novak’s hometown of Hibbing, Minnesota, where the story takes place — he then dreamed up a possible culprit: a psychotic anesthetist who thinks he’s Dylan.

From there, the words flowed. “I would write whenever I was with my laptop and had a free moment: in mornings, in evenings, in gaps between cases,” said Novak, who also blogs about anesthesia topics. “I don’t sleep much.”

After finishing the manuscript — one year to write, another to edit — came the challenge of finding a publisher. “In anesthesia, I’m an expert,” Novak said. “In the literary world, I’m an unknown.” After 207 responses of “no, thanks” or no answer at all, he landed an agent. Two months later, she informed him that Pegasus Books had bought his debut novel.

“I started crying,” Novak admits. “I have a third grader and at the time the big word the class was learning was ‘perseverance.’ That was it exactly.”

Dr. Joseph Andresen, Editor, Santa Clara County Medical Association Medical Bulletin, from the January/February 2015 issue:

BOOK REVIEW “THE DOCTOR AND MR. DYLAN”

This past month, Dr. Rick Novak handed me a hardbound copy of his debut novel The Doctor and Mr. Dylan. Rick and I go way back. It was my first week of residency at Stanford when we first met. A newcomer to the operating room, all the smells and sounds were foreign to me despite my previous three years in the hospital as an internal medicine resident. Rick, a soft spoken Minnesotan at heart, in his second year of residency, took me under his wing and guided me through those first few bewildering months, sharing his experience and wisdom freely.

Fast-forward 30 years later. Dr. Rick Novak, a novel and mystery author? This was new to me as I sat down and opened the first page of The Doctor and Mr. Dylan. I have to admit that I didn’t know what to expect. Few books highlight a physician/anesthesiologist as a protagonist, and few books feature a SCCMA member as a physician/author. However, a medical-mystery theme novel wasn’t at the top of my must read list. With my 50-hour workweek, living and breathing medicine, imagining more emotional stress and drama was the furthest thing from my mind. However, three days later, as I turned the last page, and read the last few words. “life is a series of choices. I stuck my forefinger into the crook of the steering wheel, spun it hard to the left and …” This completed my 72-hour journey of and free moments I had, completely immersed in this story of life’s disappointments, human imperfections, and simple joys.

Rick, I can’t wait for your next book. Bravo!

Hibbingite writes twisted medical tale

HIBBING — Readers who are looking for a whodunit that will keep them up all night are in for a treat.

Hibbing native Rick Novak recently released his first book “The Doctor and Mr. Dylan,” a fiction set in Hibbing that merges anesthesia complications, a tumultuous marriage and the legend of Bob Dylan.

“The dialogue is sometimes funny, and there are lots of plot twists,” he said.

Novak said the book will not only entertain readers, but teach them about anesthesiology, Dylanology, the stressful race for elite college admission, and life on the Iron Range.

“The book is very conversational and streamlined,” he said. “I try to write as one would tell a story out loud.”

Novak said “The Doctor and Mr. Dylan” took him three years to perfect. He is currently working on his second book.

I found Rick Novak’s first novel, “The Doctor and Mr. Dylan,” a most exciting combination of biting sarcasm, mystery and daily activity spun with fresh new phrases that made me turn my ear back to listen to the literary cadence of his words again and again even though, on the other hand, I was anxious to turn the pages to see what would happen next. His brilliant handling of scenes is reminiscent of The Great Gatsby by F. Scott Fitzgerald. A compelling read!Deany Brady, author of “An Appalachian Childhood”

This review is from: The Doctor and Mr. Dylan (Kindle Edition)

Just finished Dr. Novak’s delightful novel. I sincerely enjoyed his honest take about the pressures and values that exist within California’s Silicon Valley. He also brought the North Country of Minnesota to life with memorable characters and a twisting, addictive plot. Buried beneath the fun and funny story is a deeper message about how to best care for your kids, your relationships and yourself. Very well written and highly recommended.

DO YOU NEED AN ANESTHESIOLOGIST FOR ENDOSCOPY OF YOUR ESOPHAGUS, STOMACH, AND UPPER GASTROENTEROLOGIC TRACT?

THE ANESTHESIA CONSULTANT

Do you need an anesthesiologist for upper gastrointestinal endoscopy? In the aftermath of Joan Rivers’ tragic death following an upper endoscopy procedure at a New York outpatient surgery center, every news bureau is discussing this topic. Because I have no inside information on Joan Rivers’ medical care during her procedure, I will not judge her physicians, rather I will attempt to answer the specific question:

Do you need an anesthesiologist for an upper gastrointestinal endoscopy?

The answer to the question is:  it depends.  It depends on 1) your health, 2) the conscious sedation skills of your gastroenterologist, and 3) the facility you have your endoscopy at.

1)  YOUR HEALTH. The majority of endoscopies in the United States are performed under conscious sedation.  Conscious sedation is administered by a registered nurse, under specific orders from the gastroenterologist.  The typical drugs are Versed (midazolam) and fentanyl.  Versed is a benzodiazepine, or Valium-like medication, that is superb in reducing anxiety, sleepiness, and producing amnesia.  Fentanyl is a narcotic pain reliever, similar to a short-acting morphine.  The combination of these two types of medications renders a patient sleepy but awake.  Most patients can minimal or no recollection of the endoscopy procedure when under the influence of these two drugs.  I can speak from personal experience, as I had an endoscopy myself, with conscious sedation with Versed and fentanyl, and I remembered nothing of the procedure.

If you are a reasonably healthy adult, you should be fine having the procedure under conscious sedation.  Patients with high blood pressure, diabetes, asthma, obesity, mild to moderate sleep apnea, advanced age, or stable cardiac disease are have conscious sedation for colonoscopies in America every day, without significant complications.

Certain patients are not good candidates for conscious sedation, and require an anesthesiologist for sedation or general anesthesia.  Included in this category are a) patients on large doses of chronic narcotics for chronic pain, who are tolerant to the fentanyl and are therefore difficult to sedate, b) certain patients with morbid obesity, c) certain patients with severe sleep apnea, and d) certain patients with severe heart or breathing problems.

2)  THE CONSCIOUS SEDATION SKILLS OF YOUR GASTROENTEROLOGIST.  Most gastroenterologists are comfortable directing registered nurses in the administration of conscious sedation drugs.  Some, however, are not.  These gastroenterologists will disclose this to their patients, and recommend that an anesthesiologist administer general anesthesia for the procedure.

3) THE FACILITY YOU HAVE YOUR ENDOSCOPY AT.  Most endoscopy facilities have nurses and gastroenterologists comfortable with conscious sedation.  Some do not.  The facility you are referred to may have a consistent policy of having an anesthesiologist administer general anesthesia with propofol for all endoscopies.  If this is true, they should disclose this to you, the patient, before you arrive for the procedure.  A facility which always utilizes general anesthesia means that you, the patient, will incur one extra physician bill for your procedure, from an anesthesiologist.

I refer you to an article from the New York Times, which summarizes the anesthesiologist-propofol-for-endoscopy phenomenon in the New York region in 2012:

One last point: If the drugs Versed and fentanyl are used, there exist specific and effective antidotes for each drug if the patient becomes oversedated. The antagonist for Versed is Romazicon (flumazenil), and the antagonist for fentanyl is Narcan (naloxone). If these drugs are injected promptly into the IV of an oversedated patient, the patient will wake up in seconds, before any oxygen deprivation affects the brain or heart.

Propofol, however, has no specific antagonist. Propofol only wears off as it is redistributed out of the blood stream into other tissues, and its blood level declines. A propofol overdose can cause obstruction of breathing, and/or depression of breathing, such that the blood oxygen level is insufficient for the brain and heart. The Food and Drug Administration (FDA) mandates that a Black Box warning be included in the packaging of every box of propofol. That warning states that propofol “should be administered only by persons trained in the administration of general anesthesia and not involved in the conduct of the surgical/diagnostic procedure.”

Anesthesiologists are experts at using propofol. I administer propofol to 99% of my patients who are undergoing general anesthesia for a surgical procedure. Anesthesiologists are experts at managing airways and breathing. Individuals who are not trained to administer general anesthesia should never administer propofol to a patient, in a hospital or in an outpatient surgery center.

I serve as the medical director of an outpatient surgery center in Palo Alto, California. We perform a variety of orthopedic, head and neck, plastic, ophthalmic, and general surgery procedures safely each year. In addition, our gastroenterologists perform thousands of endoscopies each year. I review the charts of the endoscopy patients as well as the surgical patients prior to the procedures, and in our center, approximately 99% of endoscopies can be safely performed under Versed and fentanyl conscious sedation, without the need for an anesthesiologist attending to the patient.

If you have an endoscopy, ask questions. Will you receive conscious sedation with drugs like Versed and fentanyl, or will an anesthesiology professional administer propofol? You deserve to know.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

HERBAL MEDICINES, SURGERY, AND ANESTHESIA

THE ANESTHESIA CONSULTANT

An otherwise healthy 50-year-old female patient takes three herb pills daily: gingko, kava, and ginseng. What do you do when this patient needs elective surgery for an ACL reconstruction two days from now? Do you cancel surgery and stop the herbal medicines, or should you proceed?

My goal is to give you practical advice on how to proceed in the real world of anesthesia and surgical practice. We all know herbal medicines are out there. Do they matter? What is the evidence that herbal medicines affect surgical outcomes in an adverse way?

Many commonly used herbal medicines have side effects that affect drug metabolism, bleeding, and the central nervous system. In 2002 35% of Americans used complementary alternative medicine (CAM) therapies, and visits to CAM practitioners exceeded those to American primary care physicians (Tindle et al: Trends in use of complementary and alternative medicine by US adults: 1997-2002. Altern Ther Health Med 2005; 11:42). CAM practitioners include homeopathic medicine, meditation, art, music, or dance therapy, herbal medicines, dietary supplements, chiropractic manipulation, osteopathic medicine, massage, and acupuncture.

The finest review of herbal medicines and anesthesia is Chapter 33 in Miller’s Anesthesia, 7th Edition, 2009, authored by Ang-Lee, Yuan, and Moss. The authors write, “Many patients fail to volunteer information regarding herb and alternative medicine pills unless they are specifically asked about herbal medication use. Scientific knowledge in this area is still incomplete. There are no randomized, controlled trials that have evaluated the effects of prior herbal medicine use on the period immediately before, during and after surgery.” They go on to say, “preoperative use of herbal medicines has been associated with adverse perioperative events,” and “Because herbal medicines are classified as dietary supplements, they are not subject to preclinical animal studies, premarketing controlled clinical trials, or postmarketing surveillance. Under current law, the burden is shifted to the U.S. Food and Drug Administration (FDA) to prove products unsafe before they can be withdrawn from the market.”

The authors reviewed nine herbal medicines that have the greatest impact on perioperative patient care: echinacea, ephedra, garlic, Ginkgo biloba, ginseng, kava, saw palmetto, St. John’s wort, and valerian. These nine pills represent 50% of the herbal medicines sold in the United States.

The same authors published a paper entitled “Herbal Medicines and Perioperative Care.” (JAMA 2001; 286:208). The following table is reproduced from that journal article, and describes relevant effects, perioperative concerns, and recommendations for eight of the most common herbal medicines:

Echinacea
Boosts immunity. Allergic reactions, impairs immune suppressive drugs, can cause 
immune suppression when taken long-term, could impair wound 
healing. Discontinue as far in advance as possible, especially for transplant patients or those with liver dysfunction.

Ephedra (ma huang) Increases heart rate, increases blood pressure. Risk of heart attack, arrhythmias, stroke, interaction with other drugs, kidney stones. Discontinue at least 24 hours before surgery.

Garlic (ajo)
Prevents clotting. Risk of bleeding, especially when combined with other drugs that inhibit clotting. Discontinue at least 7 days before surgery.

Ginko (duck foot, maidenhair, silver apricot). Prevents clotting. Risk of bleeding, especially when combined with other drugs that inhibit clotting. Discontinue at least 36 hours before surgery.

Ginseng
Lowers blood glucose, inhibits clotting. Lowers blood-sugar levels. Increases risk of bleeding. Interferes with warfarin (an anti-clotting drug). Discontinue at least seven days before surgery.

Kava (kawa, awa, intoxicating pepper). Sedates, decreases anxiety. May increase sedative effects of anesthesia. Risks of addiction, tolerance and withdrawal unknown. Discontinue at least 24 hours before surgery.

St. John’s wort (amber, goatweed, Hypericum, klamatheweed). Inhibits re-uptake of neuro-transmitters (similar to Prozac). Alters metabolisms of other drugs such as cyclosporin (for transplant patients), warfarin, steroids, protease inhibitors (vs HIV). May interfere with many other drug.s Discontinue at least five days before surgery.

Valerian
Sedates Could increase effects of sedatives. Long-term use could increase the amount of anesthesia needed. Withdrawal symptoms resemble Valium addiction If possible, taper dose weeks before surgery. If not, continue use until surgery. Treat withdrawal symptoms with benzodiazepines.

In their chapter in Miller’s Anesthesia, Ang-Lee, Yuan, and Moss recommend that, “In general, herbal medicines should be discontinued preoperatively. When pharmacokinetic data for the active constituents in an herbal medication are available, the timeframe for preoperative discontinuation can be tailored. For other herbal medicines, 2 weeks is recommended. However, in clinical practice because many patients require nonelective surgery, are not evaluated until the day of surgery, or are noncompliant with instructions to discontinue herbal medications preoperatively, they may take herbal medicines until the day of surgery. In this situation, anesthesia can usually proceed safely at the discretion of the anesthesiologist, who should be familiar with commonly used herbal medicines to avoid or recognize and treat complications that may arise.”

The American Society of Anesthesiologists have no official standards or guidelines on the preoperative use of herbal medications. Public and professional educational information released by the American Society of Anesthesiologists suggest that herbals be discontinued at least 2 to 3 weeks before surgery.

To return to our original question, what do you do when your otherwise healthy 50-year-old female patient has been taking gingko, kava, and ginseng up to two days prior to her ACL reconstruction surgery? Gingko can cause increased bleeding, kava can cause increased sedation, and ginseng can cause decreased blood sugars and increased bleeding. You discuss the predicament with the patient’s surgeon. He’s not concerned that a possible increased risk of bleeding will affect this knee surgery. You decide the increased level of sedation and the possible decreased blood sugar risks are not prohibitive. (If you were worried, you could cut back slightly on the amount of central nervous system depressant drugs you utilize, and also run a 5% dextrose solution in the patient’s IV.)

An alternative choice would be to cancel the surgery for 2 weeks while the patient remains herb-free. The surgeon asks you, “Is there any data that postponing the surgery for two weeks will decrease the complication rate?”

You answer honestly and say, “There is no data. The American Society of Anesthesiologists suggests that herbals be discontinued at least 2 to 3 weeks before surgery.”

The surgeon says, “I want to do the case tomorrow. There’s no data compelling me to delay for two weeks. I accept whatever increased bleeding risk there may be. I’ve never had a patient have a bleeding complication from a knee surgery.”

You proceed with the surgery the next day. The patient does well, and has no complications.

Surveys estimate that:
a) 22% to 32% of patients undergoing surgery use herbal medications (Tsen LC, et al: Alternative medicine use in presurgical patients. Anesthesiology 2000; 93:148);
b) 90% of anesthesiologists do not routinely ask about herbal medicine use (McKenzie AG: Current management of patients taking herbal medicines: A survey of anaesthetic practice in the UK. Eur J Anaesthesiol 2005; 22:597); and
c) more than 70% of patients are not forthcoming about their herbal medicine use during routine preoperative assessment (Kaye AD, et al: Herbal medications: Current trends in anesthesiology practice—a hospital survey. J Clin Anesth 2000; 12:468).

The frequent use of herbal medicines in perioperative patients is real. How big a problem is it? Nobody knows. How frequently does one of your patients have an unexpected problem of increased bleeding, increased sedation, decreased blood sugar, unexpected cardiac arrhythmia or angina, or decreased immune function?

For an ACL reconstruction in a healthy patient, gingko, kava, and ginseng may pose little risk. For a craniotomy on a 70-year-old with coronary artery disease and diabetes, gingko, kava, and ginseng bay pose an increased risk, and warrant postponing the surgery for 2 weeks after holding the herbal medicines.

My advice is to take a careful history of herb medicine use from your patients, know (or look it up if you don’t remember) the potential side effects of each herbal medicine, and then on a case-by-case basis decide if it really matters if the surgery should be cancelled for 2 weeks.

That’s what doctors do. That’s what anesthesia consultants do.

SUCCINYLCHOLINE: VITAL DRUG OR OBSOLETE DINOSAUR?

THE ANESTHESIA CONSULTANT

Succinylcholine: vital drug or dinosaur? Succinylcholine (sux) has the wonderful advantage of rendering a patient paralyzed in less than a minute, and the discouraging disadvantage of a long list of side effects that make the drug problematic.

succinylcholine_chloride_10_med-21

A vial of succinylcholine

I would never begin an anesthetic without succinylcholine being immediately available. No other muscle relaxant supplies as rapid an onset of action and as short a duration of action. An intravenous dose of 1 mg/kg of succinylcholine brings complete paralysis of the neuromuscular junction at 60 seconds, and recovery to 90% of muscle strength in 9 – 13 minutes. (Miller’s Anesthesia, 7th Edition, 2009, Chapter 29, Pharmacology of Muscle Relaxants and Their Antagonists). If a patient has an acute airway disaster on induction such as laryngospasm or pulmonary aspiration, no drug enables emergency endotracheal intubation as quickly as succinylcholine. That said, I never use succinylcholine unless I have to. The drug has too many side effects and rocuronium is often a better choice. For an elective anesthetic on a patient who has fasted and has an empty stomach, one almost never needs to use succinylcholine. If you do use sux, you are exposing your patient to the following side effects:

1. Myalgias. Your patient complains to you the following day, “Doc, I feel like I was run over by a truck.” Because the majority of anesthetics are currently done on outpatients, and because you do not personally interview these patients the following day, you won’t be aware of the degree of muscle pain you’ve induced by using the depolarizing relaxant succinylcholine. Published data quantitates the incidence of post-succinylcholine myalgia as varying from 0.2 % to 89% (Brodsky JB, Anesthesiology 1979; 51:259-61), but my clinical impression is that the number is closer to 89% than it is to 0.2%. Myalgias aren’t life-threatening, but if you ever converse with your patient one day after succinylcholine and they complain of severe muscle aches, you’ll wish you’d chosen another muscle relaxant if possible.
2. Risk of cardiac arrest in children. Succinylcholine carries a black box warning for use in children. Rare hyperkalemia and ventricular arrhythmias followed by cardiac arrest may occur in apparently healthy children who have an occult muscular dystrophy. The black box warning on succinylcholine recommends to “reserve use in children for emergency intubation or need to immediately secure the airway.”
3. Hyperkalemia, with an average increase of 0.5 mEq in potassium concentration after intravenous succinylcholine injection.
4. Cardiac arrest in patients with a history of severe trauma, neurologic disease or burns. There’s a risk of cardiac arrest with succinylcholine use in patients with severe burns, major trauma, stroke, prolonged immobility, multiple sclerosis, or Guillian-Barré syndrome, due to an up-regulation of acetylcholine. The increase in serum potassium normally seen with succinylcholine can be greatly increased in these populations, leading to ventricular arrhythmia and cardiac arrest. There is typically no risk using succinylcholine in the first 24 hours after the acute injury.
5. Cardiac arrhythmias. Both tachy and bradycardias can be seen following the injection of succinylcholine.
6. Increase in intraocular pressure, a hazard when the eye is open or traumatized.
7. Increase in intragastric pressure, a hazard if gastric motility is abnormal or the stomach is full.
8. Increase in intracranial pressure, a hazard with head injuries or intracerebral bleeds or tumors.
9. Malignant Hyperthermia (MH) risk. The incidence of MH is low. A Danish study reported one case per 4500 anesthetics when triggering agents are in use (Ording H, Dan Med Bull, 43:111-125), but succinylcholine is the only injectable drug which is a trigger for MH, and this is a disincentive to use the drug routinely.
10. Prolonged phase II blockade. Patients who have genetically abnormal plasma butyrylcholinesterase activity have the risk of a prolonged phase II succinylcholine block lasting up to six hours instead of the expected 9 – 13 minutes. If you’ve ever had to stay in the operating room or post-anesthesia recovery room for hours with a ventilated patient after their surgery ended because your patient incurred prolonged blockade from succinylcholine, you won’t forget it, and you’ll hope it never happens again.

What does a practicing anesthesiologist use instead of succinylcholine? Rocuronium.

A 0.6 mg/kg intubating dose of the non-depolarizing relaxant rocuronium has an onset time to maximum block of 1.7 minutes and a duration of 36 minutes. The onset time can be shortened by increasing the dose to a 1.2 mg/kg, a dose which has an onset time to maximum block of 0.9 minutes and a duration of 73 minutes. These durations can be shortened by reversing the rocuronium blockade as soon as one twitch is measured with a neuromuscular blockade monitor. Thus by using a larger dose of rocuronium, practitioners can have an onset of acceptable intubation conditions at 0.9 X 60 seconds = 54 seconds, compared to the 30 seconds noted with succinylcholine, without any of the 10 above-listed succinylcholine side effects. The duration of rocuronium when reversed by neostigmine/glycopyrrolate can be as short as 20 – 25 minutes, a time short enough to accommodate most brief surgical procedures.

Now that sugammadex is commercially available, we can reverse rocuronium blockade in seconds, making rocuronium shorter in duration than succinylcholine.

Here is a list of surgical cases once thought to be indications for using succinylcholine, which I would argue are now better served by using a dose of rocuronium followed by early reversal with sugammadex:

1) Brief procedures requiring intubation, such as bronchoscopy or tonsillectomy.
2) Procedures which require intubation plus intraoperative nerve monitoring, such as middle ear surgery.
3) Procedures requiring intubation of obese and morbidly obese patients who appear to have no risk factors for mask ventilation.
4) Procedures requiring full stomach precautions and cricoid pressure, in which the patient’s oxygenation status can tolerate 54 seconds of apnea prior to intubation. This includes emergency surgery and trauma patients. Miller’s Anesthesia (Chapter 72, Anesthesia for Trauma) discusses the induction of anesthesia and endotracheal intubation for emergency patients who are not NPO and may have full stomachs. Either succinylcholine or rocuronium can be used, with succinylcholine having the advantage of a quicker onset and the 1.2 mg/kg of rocuronium having the advantage of lacking the 10 side effects listed above. The fact that succinylcholine takes 9 – 13 minutes to wear off makes it riskier than rocuronium, which can be reversed in seconds by sugammadex. Waiting for 9 minutes for a return to spontaneous respirations after succinycholine would be associated with severe hypoxia.

On the other hand, succinylcholine is the sole recommended muscle relaxant for:

1) Cesarean sections. Miller’s Anesthesia (Chapter 69, Anesthesia for Obstetrics) still recommends thiopental and succinylcholine for Cesarean sections that require general anesthesia, and I would be loath to disagree with our specialty’s Bible.
2) Electroconvulsive therapy (ECT) for depression. Miller’s Anesthesia (Chapter 79, Anesthesia at Remote Locations) recommends partial muscle relaxation during ECT, and recommends small doses of succinylcholine (0.5 mg/kg) to reduce the peripheral manifestations of the seizure and to prevent musculoskeletal trauma to the patient.
3) Urgent intubation or re-intubation in a patient when every second counts, e.g. a patient who is already hypoxic. A subset of this indication is the patient who is being mask-induced and becomes hypoxic and requires intramuscular succinylcholine injection.
4) Laryngospasm either during mask induction or post-extubation, in which the patient requires urgent paralysis to relax the vocal cords.

In conclusion, most indications for muscle relaxation are better handled by using the non-depolarizing drug rocuronium rather than succinylcholine. However, because of the four recommended uses for succinylcholine listed in the previous paragraph, none of us would ever practice anesthesia without a vial of succinylcholine in our drawer for immediate availability.

I try very, very hard to minimize my use of succinylcholine, and so should you. But to answer our original question… succinylcholine is still a vital drug and not a dinosaur at all.

OPERATING ROOM BULLYING

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Does operating room bullying occur? You’re a freshly trained, recently hired anesthesiologist at a new medical center. In your first week on your job, an attending surgeon in the operating room intimidates you, making aggressive, sarcastic, and critical comments such as, “Are you trying to kill my patient? Have you ever done this before? Why is it taking you so long to get this patient to sleep?” or “My patient just moved. Can’t you give anesthesia better than that? Maybe I’d better ask for a different anesthesiologist.”

Does this ever happen? Unfortunately it does. What do you do?

Bullying in the medical profession is common, particularly during training years. A 1990 study (Silver HK, Medical student abuse. Incidence, severity, and significance, JAMA 1990 Jan 26;263(4):527-32) found that 46.4 percent of students at one major medical school had been abused at some point. By the time they were seniors, that number rose to 80.6 percent. In an Irish study, 30% of junior hospital physician responders to a questionnaire claimed to have been subjected to one or more bullying behaviors. (Cheema S, Bullying of junior doctors prevails in Irish health system: a bitter reality, Ir Med J. 2005 Oct;98(9):274-5).

The traditional medical education hierarchy of attendings > fellows > residents > interns > medical students sets up a pecking order where senior physicians pick on junior colleagues. One might paraphrase the phenomenon as “Sh__ runs downhill.” Younger colleagues are expected to do more “scut,” that is more paper work, computer work, contacting of consultants, chasing down lab and scan results, early rounds and late rounds on patients, as well as to sleep overnight in hospitals.

As physicians become more senior and exit training programs, their lifestyle improves and junior doctors, physician assistants, nurse practitioners, or registered nurses do more of their work. The tradition of condescending behavior toward those less trained may continue. When condescension crosses the line into disruptive or inappropriate behavior, it becomes a problem. Abused physicians, nurses, or techs can become angry or depressed, lose self esteem, and their physical and emotional health may suffer. Disrespect and bullying compromise patient safety because they inhibit the collegiality and cooperation essential to teamwork, cut off communication, and destroy team morale.

Joint Commission studies have shown that communication failure between health care workers is the number one cause for medication errors, delays in treatment, and surgeries at the wrong site. A 2004 study of workplace intimidation by the Institute for Safe Medication Practices (ISMP) (www.ismp.org/pressroom/pr20040331.pdf) found that nearly 40 percent of clinicians have kept quiet or ignored concerns about improper medication rather than talk to an intimidating colleague.Rather than bring their questions about medication orders to a difficult doctor, these health care personnel said they would preferred to keep silent. Seven percent of the respondents said that in the past year they’d been involved in a medication error in which intimidation was at least partly responsible.

In 2009 the Joint Commission began requiring hospitals to have a “code of conduct that defines acceptable, disruptive, and inappropriate staff behaviors” and for its “leaders [to] create and implement a process for managing disruptive and inappropriate staff behaviors.” The rationale for the standard states: “Leaders must address disruptive behavior of individuals working at all levels of the [organization], including management, clinical and administrative staff, licensed independent practitioners, and governing body members.”

Stanford University Hospital where I work has adopted such a Medical Staff Code of Professional Behavior (found online at medicalstaff.stanfordhospital.org/bylaws/documents/Code_of_Behavior).

Excerpts from this document include:

“Inappropriate behavior” means conduct that is unwarranted and is reasonably interpreted to be demeaning or offensive. Persistent, repeated inappropriate behavior can become a form of harassment and thereby become disruptive, and subject to treatment as “disruptive behavior.” Inappropriate behavior include, but are not limited to, the following: Belittling or berating statements; Name calling; Use of profanity or disrespectful language; Inappropriate comments written in the medical record; Blatant failure to respond to patient care needs or staff requests; Personal sarcasm or cynicism; Lack of cooperation without good cause; Refusal to return phone calls, pages, or other messages concerning patient care; Condescending language; and degrading or demeaning comments regarding patients and their families, nurses, physicians, hospital personnel and/or the hospital.

“Disruptive behavior” means any abusive conduct including sexual or other forms of harassment, or other forms of verbal or non-verbal conduct that harms or intimidates others to the extent that quality of care or patient safety could be compromised.

Disruptive behavior by Medical Staff members is prohibited. Examples of disruptive behavior include, but are not limited to, the following: Physically threatening language directed at anyone in the hospital including physicians, nurses, other Medical Staff members, or any hospital employee, administrator or member of the Board of Directors; Physical contact with another individual that is threatening or intimidating; Throwing instruments, charts or other things.

This is how the Stanford policy deals with inappropriate or disruptive behavior:

          If this is the first incident of inappropriate behavior, the Chief of Staff (COS)or designee shall discuss the matter with the offending Medical Staff member, emphasizing that the behavior is inappropriate and must cease. The offending Medical Staff member may be asked to apologize to the complainant. The approach during this initial intervention should be collegial and helpful.

            Further isolated incidents that do not constitute persistent, repeated inappropriate behavior will be handled by providing the offending Medical Staff member with notification of each incident, and a reminder of the expectation the individual comply with this Code of Behavior.

          If the COS or designee determines the Medical Staff member has demonstrated persistent, repeated inappropriate behavior, constituting harassment (a form of disruptive behavior), or has engaged in disruptive behavior on the first offense, the case will be referred to the COS and/or the Committee on Professionalism (COP). The subject will be notified of this decision and given an opportunity to provide a written response both prior to and subsequent to meeting with the COS or COP.

            If it is determined that the subject has engaged in disruptive behavior, a letter of admonition will be sent to the offending member, and, as appropriate, a rehabilitation action plan developed by the COS and/or COP, with the advice and counsel of the medical executive committee as indicated. The assistance of the Wellbeing Committee may be offered at any stage of this process.

             If, in spite of this admonition and intervention, disruptive behavior recurs, the COS or designee shall meet with and advise the offending Medical Staff member such behavior must immediately cease or corrective action will be initiated. This “final warning” shall be sent to the offending Medical Staff member in writing.

            If after the “final warning” the disruptive behavior recurs, corrective action (including possible suspension or termination of privileges) shall be initiated pursuant to the Medical Staff bylaws of which this Code of Behavior is a part, and the Medical Staff member shall have all of the due process rights set forth in the Medical Staff bylaws.

What do you do when inappropriate or disruptive behavior occurs in your operating room? The specialty of anesthesia provides wonderful positives such as intellectual challenge, multiple different subspecialties, hands-on procedures, and solid financial reimbursement. A disadvantage of the specialty of anesthesia is that anesthesiologists are consultants who do not have their own patients. No patient goes to the hospital or surgery center solely to have an anesthetic. Patients are there for some invasive procedure that requires an anesthetic.

Because the patient “belongs” to the surgeon, some surgeons use this fact to lord power over the anesthesiology provider, the operating room nurses, and surgical technicians, as well as over the hospital administration. A busy surgeon with a hefty workload brings a great deal of revenue to the hospital or surgery center he or she chooses to operate at. Some surgeons feel entitled to exercise condescending behavior toward nurses and anesthesiologists who they perceive to be merely part of hospital or surgery center services. Some surgeons yell, cuss, and throw things. Some engage in more subversive behaviors such as ignoring questions, acting impatient, insulting colleagues or speaking to them in condescending tones. Only a small percent of surgeons are bad actors, but a small proportion can have a big impact.

In my 25-year anesthesia career I’ve seen multiple examples of verbally and emotionally abusive surgeons. In distant years most of these surgeons met little resistance to their behavior. Staff who opposed them were moved to different operating rooms, and more enabling nurses and techs were found. The enablers were quiet, agreeable, hard working, and rarely questioned the surgeon’s authority. Anesthesiologists who resisted surgeon bullying stopped working with that surgeon, per both the surgeon and the anesthesiologist’s wishes. Alternate anesthesia providers were tried until a subgroup of passive enabler anesthetists was found.

My advice to any anesthesiologist out there is: Don’t be an enabler. You are a highly trained physician, deserving of respect. If a surgeon has an episode of acting disrespectfully to you or to any of the other operating room staff, conclude your care of that current patient without a confrontation. After the case is finished, choose a time to hold a face-to-face conversation with the surgeon. The setting could be a hallway, in the locker room, or at some other location where no patient care is being done. Tell him or her that you find their behavior toward you unacceptable, and that they need to stop it. If you get pushback, and you probably will, you have several choices: 1) have a loud verbal argument, asserting your will against theirs, 2) grin, bear it, and stop complaining about the circumstance; 3) request your scheduler to never schedule you with this surgeon again; or 4) kick it upstairs to the chief of the department and/or the chief of the surgery department.

Which option should you choose?

1) gets you a boisterous unprofessional argument with an individual who will be resistant to change. 2) results in a long-term unacceptable solution for you and your professional esteem. 3) gets you off the hook but does nothing to change the situation for others in the operating room. Only 4) will set the wheels in motion toward significant change. Stay calm and confident and refer the incident up to senior physician administrators to evoke change. If the department chairs can not impact behavioral change, take the issue higher to the Chief of Staff.

A genuine problem occurs when a bullying surgeon leaves all major medical centers and starts his or her own surgery center where he or she is the Medical Director and his or her bad behavior goes unscrutinized. If you are working in such a setting, I’d advise you to find another place to give anesthetics. Without an unbiased administrator, the surgeon bullying behaviors will never go away.

You’ll be happier working in an operating room cured of disruptive behavior, and the real winners will be the patients, who will come and go through a hospital free of disruptive behavior and bullying.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

STARTING A COMPANY: THE PHYSICIAN ENTREPRENEUR

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Anesthesiologists spend thousands of hours in operating rooms, surrounded by other people’s inventions. We may think, “Why can’t I be a physician entrepreneur? Why can’t I start a company to invent something like the pulse oximeter (i.e. Dr. Bill New, Stanford anesthesiologist-engineer), the laryngeal mask airway (i.e. Dr. Archie Brain of England), or even the Bair Hugger? Heck, I use a hair dryer every morning. Why didn’t I realize how useful hot air could be in warming surgical patients?”

physician

In a recent Stanford Anesthesia Grand Rounds lecture, anesthesiologist-entrepreneur Jeffery Bleich, MD discussed this very topic. How does a physician go about converting his idea into a medical technology company? Dr. Bleich is a unique individual, a board-certified anesthesiologist and pain medicine specialist who completed Stanford Business School’s Sloan Fellowship and founded not one but two Silicon Valley medical companies. These are some highlights from Dr. Bleich’s lecture:

  1. Anesthesiologists can be ideally suited for starting companies, because our specialty interfaces with all aspects of medicine, from neonates to geriatrics, from cardiac and brain surgery to ambulatory procedures such as orthopedics, ENT, and plastics. Anesthesiologists have ample time to contemplate new ideas as they take part in surgical and medical interventions, and we have the ability to create flexible schedules to explore entrepreneurial ventures.
  2. Dr. Bleich recommends a 20-year plan as an approach to starting a medical business. Where you want to be in 20 years dictates what decisions you will make regarding your future 10 years from now, 5 years from now, and most importantly, today.
  3. Think of a Problem that needs a better solution. Then the most important ingredients in your plan are Team > Market > Idea. One might think that the Idea is the key to starting a company, but Dr. Bleich stressed that an excellent Team comes first. If one assembles an excellent Team to approach a big Market, the Idea will develop out of Team and Market.
  4. Find a Mentor. A seasoned role model who has started a company prior to you will be your greatest asset in guiding you through the process. For a modest percentage of ownership in the venture, recruit a Mentor. In the Stanford geographical area, Silicon Valley is a rich resource of such individuals.
  5. “Kill ‘em Quick.” This phrase refers to the concept of killing bad ideas quickly. Try to criticize and defeat each new idea you have. If you are capable of killing the idea in short order, this is preferable to investing years of time and quantities of dollars only to find the idea is not viable. If you can’t kill the idea quickly, go with it.
  6. Expertise + Passion = Magic. Passion is necessary and contagious. If you have Passion for the Idea and the Expertise to back it up, your likelihood for success grows.
  7. Deliver. This requires sweat and effort. Dr. Bleich reports that starting a company becomes a 7-day a week project that infringes on family time, traditional work time, and free time. He stresses that intellectual honesty and execution are needed to keep the company on path. The need to “make a difference” in the world can be an overriding theme that keeps the work on track.
  8. Funding. From 2004-2009, Dr. Bleich was the Founder and CEO of Baxano, Inc, a company that developed both a minimally invasive procedure and instruments to approach lumbar stenosis surgery. In the company’s infancy, Dr. Bleich was the sole owner of Baxano, Inc. During the ensuing years, Baxano raised $70 million in venture capital money to support the company. Eventually the company merged with a public company in an acquisition.
  9. A cautionary tale: Dr. Bleich described venture capital (VC) funding as an “extremely financially risky path,” particularly in the medical technology industry today. However, he added, if you can obtain this type of financial capital, it does provide a sort of “rocket fuel” that can enable a company to attempt to grow a business very quickly. Unfortunately, it also requires giving up control of the company’s major financial decisions to the Venture investors.
  10. Dr. Bleich has since founded a second company, Pulson, Inc., where he again serves as President and CEO. This time around he’s been able to avoid VC funding, partly because Pulson, as a software company focused on consumer health, requires less overhead than did Baxano, a medical device company developing minimally invasive surgical tools. Forgoing the “rocket fuel” the venture capitalists offer means the new company has grown more slowly than a typical VC funded enterprise, but bootstrapping the company in this manner has allowed control of the company to remain with the founders, which so far appears to have been worth the tradeoff.
  11. Dr. Bleich described the current financing climate for medical device companies as a “wasteland.” It’s his personal opinion that the federal government, appropriately concerned with out of control inflation in medical care costs, has recognized that proprietary new medical devices are typically very expensive compared to generic devices, yet more often than not they are at best only marginally better than old technology. In order to shut down expensive new proprietary products from hitting the market, the government has three ”levers” that it can pull to suppress medical device innovation:  a) it can make it more difficult to get products approved or cleared through the Food and Drug Administration (FDA);  b) it can make it more difficult for new products to gain reimbursement through Centers for Medicare & Medicaid (CMS);  and c) it can (and did) add punitive new taxes that specifically target medical devices. These factors have combined to increase the risk and cost of bringing new medical technologies to market, while decreasing the value of the few that actually make it, causing many of the finest investors across the medical technology industry to leave for greener pastures.
  12. Dr. Bleich encouraged would-be entrepreneurs to not be discouraged by the lack of interest in medical technology investing as we used to know it. In fact, he described a silver lining in these dark clouds, and provided examples of newly emerging areas in healthcare innovation that are bursting with future promise. He suggested that some of the best new territories for medical innovation include the individual and converged categories of: a) wireless technology, b) genomics, and c) Big Data.
  13. What about the value of a physician going to business school and gaining a business degree? Dr. Bleich graduated from Stanford Business School, one of the world’s elite business schools. Was it worth it? Dr. Bleich admits it helped him approach the business world with more confidence. The degree itself didn’t help him find a job that was of particular interest to him, because an MD with one year of business school is very unlikely to be able to qualify for a high level business position. After interviewing with a couple of large medical technology companies, he soon realized the only way he would be able to find a job in the business world that gave him the level of responsibility he was looking for was to create the company himself. Not surprisingly, when he founded his own company, Baxano, as the only employee, he hired himself as CEO.
  14. With MD salaries as high as or higher than most mid-level business jobs, and with the income potential of MD’s still relatively high, Dr. Bleich stressed that the motivation to go into business and start a company should not be money. “If your major motivation is simply to make a fortune, your odds would be better rolling the dice at a craps table in Las Vegas than starting a medical company,” he said. “It’s a gamble either way. You should become an entrepreneur because you know in your heart that you cannot go to the grave without trying to make the world a better place with your business idea.”

I thank Dr. Jeffery Bleich for his expertise, candid remarks, and advice.

The American Dream is alive and well in the 21st Century, and if you have the heart and soul of an entrepreneur, I hope you summon your intellect and your courage, and start a company that changes the world we live and work in.

APRIL 2014 LETHAL INJECTION IN OKLAHOMA – AN ANESTHESIOLOGIST’S VIEW

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

THE ANESTHESIA CONSULTANT

On April 29, 2014 CNN reported the story of the botched intravenous lethal injection execution of convicted murderer Clayton Lockett in Oklahoma. The recipe included execution by three anesthetic drugs: midazolam, vecuronium, and potassium chloride.

 

Prior to the execution, medical officials tried for nearly an hour to find a vein in Clayton Lockett’s arms, legs and neck before finally inserting an IV into his groin, prisons director Robert Patton wrote in a letter to the governor May 1st detailing Lockett’s last day.

In the middle of the injection process, the convict was observed to cry out, “Man,” “I’m not,” and “something’s wrong,” before the blinds were closed to witnesses. Lockett died of a heart attack 43 minutes after the first drug was injected.

Dean Sanderford, Lockett’s attorney, stated his client’s body “started to twitch,” and then “the convulsing got worse. It looked like his whole upper body was trying to lift off the gurney. For a minute, there was chaos.”

After administering the first drug, “We began pushing the second and third drugs in the protocol,” said Oklahoma Department of Corrections Director Robert Patton. “There was some concern at that time that the drugs were not having the effect. So the doctor observed the line and determined that the line had blown.” He said that Lockett’s vein had “exploded.”

CNN further states that, “Oklahoma had announced the drugs it planned to use: midazolam; vecuronium bromide to stop respiration; and potassium chloride to stop the heart. Two intravenous lines are inserted, one in each arm. The drugs are injected by hand-held syringes simultaneously into the two intravenous lines. The sequence is in the order that the drugs are listed above. Three executioners are utilized, with each one injecting one of the drugs.”

The article further states that, “The doctor checked the IV and reported the blood vein had collapsed,and the drugs had either absorbed into tissue, leaked out or both,” according to the timeline. The director of the corrections department then asked whether Lockett had been given enough of the drug combination to kill him, and the doctor said “no.” “Is another vein available? And if so, are there enough drugs remaining?” the doctor was asked, according to the timeline.

The doctor’s answer to both questions: “No.”

Lockett’s attempted execution was carried out at the Oklahoma State Penitentiary in McAlester, where he had been housed following his conviction and death sentence for shooting Stephanie Nieman and then watching as two others buried her alive in 1999.

What happened in this apparent “botched” execution? I have no additional information other than what has been published in the lay press, but as an anesthesiologist I can make some inferences:

In the three drug combination of midazolam, vecuronium, and potassium chloride, each drug has a specific purpose. The sedative midazolam is intended to make the convicted murderer fall asleep. Midazolam (Versed) is a benzodiazepine, a drug commonly given immediately prior to surgery to relieve a patient’s anxiety. A typical adult dose is 2 mg. Midazolam is also commonly used for conscious sedation for colonoscopy procedures, when repeated 1 – 2 mg doses are titrated for relaxation. Let’s assume an executioner administered massive overdoses in the range of 50 mg of midazolam. This dose should reliably guarantee unconsciousness, unless the intravenous catheter is not properly placed inside the vein. If the IV infiltrates, only a portion of the midazolam circulates in the bloodstream, and the expected unconsciousness may not be obtained.

The second drug, vecuronium, is a paralyzing drug. Anesthesiologists commonly inject vecuronium prior to or during surgical anesthetics. Anesthesiologists first administer a hypnotic drug such as propofol to insure unconsciousness, and then administer a muscle relaxant drug such as vecuronium to paralyze the patient so a metal laryngoscope can be inserted into the patient’s mouth to facilitate the placement of a breathing tube into the trachea. The anesthesiologist will then support ventilation of the patient’s lungs by connecting the breathing tube to a ventilator. The paralyzed patient is unable to breathe on their own, and without the controlled ventilation the patient would die within minutes. This is the rationale of using vecuronium in a lethal injection cocktail. The other rationale in using a paralyzing drug such as vecuronium is that a paralyzed individual will not writhe or seize during the death process.

A concentrated dose of potassium chloride causes sudden cardiac arrest by ventricular fibrillation of the heart.

Why did the Oklahoma execution not go smoothly? As reported in the press, the intravenous line infiltrated. Why does this happen? The intravenous line was either improperly inserted, improperly secured, or it dislodged. The success of a lethal injection depends specifically on the lethal drugs being reliably delivered into the convict’s vein via a properly running IV line.

Some individuals have difficult IV access, which apparently was the case in the convict Lockett. Medical personnel typically place IV’s in arm veins, followed by legs, neck or groin as alternate locations. The placement of an IV in the groin, as was reported in Lockett’s case, is typically done by a physician, utilizing a longer IV catheter called a central venous catheter or CVP catheter. In modern hospitals, this CVP placement is often done using ultrasound imaging for increased accuracy and success. In a hospital setting, CVP placement would be done by an M.D., not by a nurse or a technician.

What was the mechanism of Lockett’s heart attack and death? I don’t know for sure, but possibilities are: 1) enough potassium chloride accumulated in his blood stream to cause his heart to arrest; 2) enough vecuronium accumulated in his blood stream to weaken his breathing so that he could not ventilate his own lungs with oxygen; or 3) a combination of 1) and 2).

Dr. Jack Kevorkian invented a euthanasia machine for assisted suicide. His machine injected three drugs that parallel the drugs used in Oklahoma: the sleep drug sodium thiopental, the paralyzing drug pancuronium, and potassium chloride. In 1999 Kevorkian was arrested for his role in executing patients in the fashion. Kevorkian was convicted of second-degree murder.

The manufacturer of the sleep drug sodium thiopental has banned the use of the product for lethal injection of prisoners. Because of this ban, there have been recent occurrences of midazolam replacing thiopental in the lethal injection recipe in the United States in 2014.

A second midazolam execution occurred in January 2014, during the lethal injection of convicted murderer Dennis McGuire at the Southern Ohio Correctional Facility in Lucasville, Ohio. This was the first time any state used the combination of midazolam and hydromorphone for an execution. It was reported that McGuire took 15 minutes to die. A reporter who witnessed the execution described McGuire as struggling, gasping loudly, snorting and making choking noises for nearly 10 minutes before falling silent and being declared dead a few minutes later. Dennis McGuire’s execution was discussed in an earlier blog entry (http://theanesthesiaconsultant.com/2014/01/16/january-2014-lethal-injection-with-midazolam-and-hydromorphone/).

Is midazolam an inferior drug to sodium thiopental for lethal injection? Probably not. In sufficiently high doses, midazolam will make any individual unconscious. An apparent flaw in McGuire’s case was the absence of a paralyzing drug and potassium chloride in the recipe. The apparent flaw in Lockett’s case was the absence of a reliable functioning IV.

Will an anesthesiologist ever insert the IV and supervise a lethal injection on death row? No. No anesthesiologist will ever use his or her skills to end a human’s life. State governments will have to find someone else to supervise lethal injections. An anesthesia doctor’s job is to keep patients alive.

HOW TO SCREEN OUTPATIENTS PRIOR TO SURGERY

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Screening prior to outpatient surgery is important. Over 70% of elective surgeries in the United States are ambulatory or outpatient surgeries, in which the patient goes home the same day as the procedure. There are increasing numbers of surgical patients who are elderly, obese, have sleep apnea, or who have multiple medical problems. How do we decide which 70% of surgical candidates are appropriate for outpatient surgery, and which are not?

Since 2002 I’ve been the Medical Director at a busy Ambulatory Surgery Center (ASC) in Palo Alto, California. ASC Medical Directors are perioperative physicians, responsible for the preoperative, intraoperative, and postoperative management of ambulatory surgery patients. Our surgery center is freestanding, distanced one mile from Stanford University Hospital. The hospital-based technologies of laboratory testing, a blood bank, an ICU, arterial blood gas measurement, and full radiology diagnostics are not available on site. It’s important that patient selection for a freestanding surgery center is precise and safe.

The topic of Ambulatory Anesthesia is well reviewed in the textbook Miller’s Anesthesia, 7th Edition, 2009, Chapter 78, Ambulatory (Outpatient) Anesthesia. With the information in this chapter as a foundation, the following 7 points are guidelines I recommend in the preoperative consultation and selection of appropriate outpatient surgery patients:

  1. The most important factor in deciding if a surgical case is appropriate is not how many medical problems the patient has, but rather the magnitude of the surgical procedure. A patient may have morbid obesity, sleep apnea, and a past history of congestive heart failure, but still safely undergo a non-invasive procedure such as a hammertoe repair. Conversely, if the patient is healthy, but the scheduled surgery is an invasive procedure such as resection of a mass in the liver, that surgery needs to be done in a hospital.
  2. Because of #1, an ASC will schedule noninvasive procedures such as arthroscopies, head and neck procedures, eye surgeries, minor gynecology and general surgery procedures, gastroenterology endoscopies, plastic surgeries, and dental surgeries. What all these scheduled procedures have in common is that the surgeries (a) will not disrupt the patient’s airway, breathing, or cardiac physiology in a major way, and (b) will not cause excessive pain requires inpatient intravenous narcotics.
  3. One must screen patients preoperatively to identify individuals who have serious medical problems. Our facility uses a comprehensive preoperative telephone interview performed by a medical assistant, two days prior to surgery. The interview documents age, height, weight, Body Mass Index, complete review of systems, list of allergies, and prescription drug history. All information is entered in the patient’s medical record at that time.
  4. Each surgeon’s office assists in the preoperative screening. For all patients who have (a) age over 65, (b) obstructive sleep apnea, (c) cardiac disease or arrhythmia history, (d) significant lung disease, (e) shortness of breath or chest pain, (f) renal failure or hepatic failure, (g) insulin dependent diabetes, or (h) significant neurological abnormality, the surgery office is required to obtain medical clearance from the patient’s Primary Care Provider (PCP).    This PCP clearance note concludes with two questions: 1) Does the patient require any further diagnostic testing prior to the scheduled surgery? And 2) Does the patient require any further therapeutic measures prior to the scheduled surgery?
  5. For each patient identified with significant medical problems, the Medical Director must review the chart and the Primary Care Provider note, and confirm that the patient is an appropriate candidate for the outpatient surgery. The Medical Director may telephone the patient for a more detailed history if indicated. On rare occasions, the Medical Director may arrange to meet and examine the patient prior to the surgical date.
  6. Medical judgment is required, as some ASA III patients with significant comorbidities are candidates for trivial outpatient procedures such as gastroenterology endoscopy or removal of a neuroma from a finger, but are inappropriate candidates for a shoulder arthroscopy or any procedure that requires general endotracheal anesthesia.
  7. What about laboratory testing? Per Miller’s Anesthesia, 7th Edition, 2009, Chapter 78, few preoperative lab tests are indicated prior to most ambulatory surgery. We require a recent ECG for patients with a history of hypertension, cardiac disease, or for any patient over 65 years in age. If this ECG is not included with the Primary Care Provider consultation note, we perform the ECG on site in the preoperative area of our ASC, at no charge to the patient. All diabetic patients have a fasting glucose test done prior to surgery. No electrolytes, hematocrit, renal function tests, or hepatic tests are required on any patient unless that patient’s history indicates a specific reason to mandate those tests.

Utilizing this system, cancellations on the day of surgery are infrequent—well below 1% of the scheduled procedures. The expense of and inconvenience of an Anesthesia Preoperative Clinic are eliminated.

What sort of cases are not approved? Here are examples from my practice regarding patients/procedures who are/are not appropriate for surgery at a freestanding ambulatory surgery center:

  1. A 45-year-old patient with moderately severe obstructive sleep apnea (OSA) is scheduled for a UPPP (uvulopalatalpharyngoplasty). DECISION: NOT APPROPRIATE. Reference: American Society of Anesthesiologist Practice Guidelines of the Perioperative Management of Patients with OSA (https://www.asahq.org/coveo.aspx?q=osa). For airway and palate surgery on an OSA patient, the patient is best observed in a medical facility post-surgery. For any surgery this painful in an OSA patient, the patient will require significant narcotics, which place him at risk for apnea and airway obstruction post-surgery.
  2. A morbidly obese male (Body Mass Index = 40) is scheduled for a shoulder arthroscopy and rotator cuff repair. DECISION: NOT APPROPRIATE. Obesity is not an automatic exclusion criterion for outpatient surgery. Whether to cancel the case or not depends on the nature of the surgery. A shoulder repair often requires significant postoperative narcotics. The intersection of morbid obesity and a painful surgery means it’s best to do the case in a hospital. One could argue that this patient could be done with an interscalene block for postoperative analgesia and then discharged home, but I don’t support this decision. If the block is difficult or ineffective, the anesthesiologist has a morbidly obese patient requiring significant doses of narcotics, and who is scheduled to be discharged home. If this surgery had been a knee arthroscopy and medial meniscectomy it could be an appropriate outpatient surgery, because meniscectomy patients have minimal pain postoperatively.
  3. An 18-year-old male with a positive family history of Malignant Hyperthermia is scheduled for a tympanoplasty. DECISION: APPROPRIATE. A trigger-free general total-intravenous anesthetic with propofol and remifenantil can be given just as safely in an ASC as in a hospital.
  4. A 50-year-old 70-kilogram male with a known difficult airway (ankylosing spondylitis) is scheduled for endoscopic sinus surgery. DECISION: NOT APPROPRIATE. In our ASC, for safety reasons, we have advanced airway equipment including a video laryngoscope and a fiberoptic laryngoscope. Despite our equipment, a patient with a known difficult airway is best scheduled for surgery in a hospital setting.
  5. An 80-year-old woman with shortness of breath on exertion is scheduled for a bunionectomy. DECISION: NOT APPROPRIATE. Although foot surgery is not a major invasive procedure, any patient with shortness of breath is inappropriate for ASC surgery. The nature of the dyspnea needs to be determined and remedied prior to surgery or anesthesia of any sort.
  6. A 6-year-old female born without an ear is scheduled for a 6-hour ear graft and reconstruction. DECISION: APPROPRIATE. With modern general anesthetic techniques utilizing sevoflurane and propofol, patients awake promptly. Even after long anesthetics, if the surgery is not painful, patients are usually discharged in stable condition within 60 minutes.

There are infinite combinations of patient comorbidities and types of surgeries. The decision regarding which scheduled procedures are appropriate and which are not is both an art and a science. The role of an anesthesiologist/Medical Director as the perioperative physician making these decisions is invaluable.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

10 WAYS PRIVATE PRACTICE ANESTHESIA DIFFERS FROM ACADEMIC ANESTHESIA

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Academic and private practice anesthesia differ. I’m fortunate to be a member of the clinical faculty in the Department of Anesthesia, Perioperative and Pain Medicine at Stanford University. Stanford is a unique academic hospital, staffed by both academic and private practice physicians. From 2001 until 2015, I served as the Deputy Chief of Anesthesia at Stanford, an elected officer who leads the private practice/community section of the anesthesia department.


IMG_0825

Stanford anesthesia residents frequently question me about how the world of private practice differs from academia. I began my writing career by penning a series of Stanford Deputy Chief Columns. These columns originated as a forum to educate residents using specific cases and situations I found unique to private practice.

Although some anesthesia residents continue in academic medicine, most pursue careers in community or private practice. In 2009, the Anesthesia Quality Institute published Anesthesia in the United States 2009, a report that summarized data on our profession. There were 41,693 anesthesiologists in America at that time, and the demographics of practice type were: academic/teaching medical center 43%, community hospital 35%, city/county hospital 11%, and ambulatory surgery center 6%. Per this data, the majority of American anesthesiologists practice outside of teaching hospitals.

How does community anesthesia differ from academic anesthesia? I’m uniquely qualified to answer this question. I’ve worked at Stanford University Hospital for 34 years, including 5 years of residency training and one year as an Emergency Room faculty member, but my last 25 years at Stanford have been in private practice with the Associated Anesthesiologists Medical Group.

Here’s my list of the 10 major adjustments residents face transitioning from academic anesthesia to private practice/community anesthesia:

  1. You’ll work alone. In academic medicine, faculty members supervise residents. In private practice, you’re on your own. This is particularly true in the middle of the night or when you are working in a small freestanding surgery center where you are the only anesthesia professional. In these settings, you have little or no backup if clinical circumstances become dire. An additional example is the performance of pediatric inhalation inductions. During residency training, a faculty member starts the IV while the resident manages the airway. In private practice you’ll do both tasks yourself. I’d advise you to adopt a senior member of your new anesthesia group as a mentor, and to question him or her in an ongoing nature regarding the nuances of your new practice. (Note that certain private practices, especially in the Midwest or Southeastern U.S., utilize Anesthesia Care Teams, where anesthesiology attendings supervise nurse anesthetists, but this model is less common in California).
  2. Income: your income will be linked to your production. The good news is that you’ll earn more money that you did as a resident. Your income will be linked to the amount of cases you do. You’ll earn more in a twelve-hour day than you do in a four-hour day, so you have an incentive to do extra cases. A job where newly hired physicians have equitable access to workload is desirable.
  3. Income: your income will be linked to the insurance coverage of your patients. Privately insured patients pay more than Medicare and Medicaid patients. You may earn more working a four-hour day for insured patients than you earn working twelve hours working for the government plans of Medicare and Medicaid. It’s too early to know how much Obamacare and the Affordable Care Act will alter physician salaries. A job with a low percentage of Medicare and Medicaid work is desirable.
  4. Vacations. You’ll have access to more vacation time than you did in academic training. Most jobs allow a flexible amount of weeks away from clinical practice, but you will earn zero money during those weeks. It will be your choice: maximize free time or maximize income.
  5. Recipes. You’ll tend to use consistent anesthesia “recipes,” rather than trying to make every anesthetic unique, interesting or educational, as you may have done in an academic setting. Community practice demands high quality care with efficient inductions and wakeups, and rapid turnovers between cases. Once you discover your best method to do a particular case, you’ll stick to that method.
  6. Continuing Medical Education (CME). In an academic setting, educational conferences are frequent and accessible. After your training is finished, you’ll need to find your own CME. In California the requirement is 50 hours of CME every 2 years. Your options will include conventions, weekend meetings, and self-study at home programs. Many physicians find at-home programs require less investment in time, travel, and tuition than finding out-of-town lectures to attend.
  7. Malpractice insurance. You’ll pay your own malpractice insurance. As a result, you’ll be intensely interested in avoiding malpractice claims and adverse patient outcomes. You’ll become well versed in the standards of care in your anesthesia community.
  8. No teaching. No one will expect you to teach during community practice. You may choose to lecture nurses or your fellow medical staff, but it’s not required.
  9. No writing. No one will expect you to write or publish scholarly articles. You may choose to do so, but you will be in the minority.
  10. 10.  Respect. You’ll experience a higher level of respect from nurses and staff at community hospitals and surgery centers than you receive during residency. Nurses and staff accept that you are fully trained and experienced, and treat you as such. Free food at lunch and breakfast is common. Some hospitals have comfortable physician lounges where medical staff members gather. Teams of physicians work together at the same community hospitals for decades, and form strong relationships with the nurses, techs, and their fellow medical staff. It feels terrific to collaborate with the same professionals week after week.

Academic training is an essential building block in every physician’s career. If and when you choose to venture beyond academia into community anesthesia, this column gives you some idea what to expect. I recommend you find a mentor to help you adjust to the challenges of your new practice setting, and I wish you good luck with the transition.

AVOIDING AIRWAY DISASTERS IN ANESTHESIA

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Every anesthesia practitioner dreads airway disasters.  Anesthesiologists and nurse anesthetists are airway experts, but anesthesia professionals are often the only person in the operating room capable of keeping a patient alive if the patient’s airway is occluded or lost. Hypoxia from an airway disaster can lead to brain damage within minutes, so there is little time for human error.

A fundamental skill is the ability to assess a patient’s airway prior to anesthesia. One must assess whether the patient will pose: 1) difficult bag-mask ventilation, 2) difficult supraglottic/laryngeal mask airway placement, 3) difficult laryngoscopy, 4) difficult endotracheal intubation, or 5) difficult surgical airway.

Of critical importance is #1) above, that is, recognizing the patient who will present difficult mask ventilation. Conditions that make for difficult bag-mask ventilation are uncommon, and usually can be detected during physical examination. Despite the importance of expertise in endotracheal intubation, I teach residents and trainees that the most important airway skill is bag-mask ventilation. Every year I encounter several patients who present unanticipated difficult intubations. In each of these patients, I’m able to mask ventilate the patient to keep them oxygenated while I try various strategies and techniques to successfully place an endotracheal tube or a laryngeal mask airway.

Most anesthesia airway disasters aren’t merely difficult intubations, but scenarios that are classified as “can’t intubate, can’t ventilate.” In these “can’t intubate, can’t ventilate” situations, the anesthesiology professional has only minutes to restore oxygenation to the patient or else the risk of permanent brain damage is very real.

The American Society of Anesthesiologists Difficult Airway Algorithm is a guide for anesthesia practitioners regarding how proceed in airway management. The algorithm is detailed, complex, comprehensive, and defines the standard of care in any medical-legal battle concerning hypoxic brain damage due difficult airway clinical cases. The algorithm is so detailed, complex, and comprehensive that some would say it’s impossible to remember every step in the acute occurrence of an airway disaster.

A simplified approach has been touted.

Dr. C. Philip Larson, Professor Emeritus, Anesthesia and Neurosurgery, Stanford University, and Professor of Clinical Anesthesiology at UCLA, and previous Chairman of Anesthesiology at Stanford, was one of my teachers and mentors for both endotracheal intubation and fiberoptic intubation. In a Letter to the Editor of the Stanford Gas Pipeline in May, 2013, Dr. Larson wrote, “there is no scientific evidence that anesthesia is safer because of the ASA Difficult Airway Algorithm.  While an interesting educational document, I question the daily clinical value of this algorithm, even in its most recent form (Anesthesiology 2013; 118:251-70). The ASA Difficult Airway Algorithm was developed by committee and has all the problems that result when done that way.  It is complex, diffuse, multi-dimensional, and all-encompassing such that it is not an instrument that one can easily adopt and practice in the clinical setting.”

Dr. Larson recommends a system of Plans A-D, a system he published in Clinical Anesthesiology, editors Morgan GE, Mikhail MS, Murray MJ, Lange Medical publication, 4th edition, 2006, pp 104-5, and in Current Reviews in Clinical Anesthesiology (2009; 30:61-72), and also in the Appendix on airway management and intubation in the newest edition of Anesthesiologists Manual of Surgical Procedures by Richard Jaffe et al (Lippincott Williams and Wilkins, 5th Edition, May 2014). An outline of the system is as follows:

A.  Plan A is direct laryngoscopy an intubation using a Miller or MacIntosh blade.

B.  If Plan A is unsuccessful, Plan B includes use of video laryngoscopy with a GlideScope or similar device.

C.  If Plan B is unsuccessful, Plan C is placement of an LMA with intubation through that LMA using a fiberoptic bronchoscope.

D.  “If Plans A-C fail,” Larson wrote in his Letter to the Editor of the Stanford Gas Pipeline in May, 2013, “one needs Plan D.  The first and perhaps the most prudent option is to cancel the proposed operation, terminate the anesthetic, and wake the patient up. The operation would be rescheduled for another day, and at that time an awake fiberoptic intubation technique would be used.  Alternatively, if the operation cannot be postponed, then the surgeon should be informed that a surgical airway (i.e.: tracheostomy) must be performed before the planned operation can commence.  To date, utilization of Plan D because of failure of Plans A-C has not occurred.”

Dr. Larson wrote that the airway skills in Plan A – C should be practiced regularly on patients with normal airways. I agree with Dr. Larson that in managing difficult airways, a practitioner needs a short list of procedural skills that he or she is expert at rather that a large array of procedures that they rarely use (such as the alternative intubation techniques using light wands or blind nasal techniques, or invasive airway procedures such as retrograde wires passed through the cricothyroid membrane or transtracheal jet ventilation through a catheter). It’s wise for anesthesiologists to regularly hone their techniques of video laryngoscopy (Plan B) and fiberoptic intubation via an LMA (Plan C) on patients with normal airways, to remain expert with these skills.

Regarding Plan B, an important advance is the availability of portable, disposable video laryngoscopes such as the Airtraq, a guided video intubation device. In my career I sometimes work in solo operating room suites distant from hospitals. In these settings, the operating room is usually not be stocked with an expensive video scope such as the GlideScope, the C-MAC, or the McGrath 5. I carry an Airtraq in my briefcase, and if the need for Plan B arises I am prepared to utilize video laryngoscopy at any anesthetizing location. I suggest the practice of carrying an Airtraq to any anesthesiologist who gives general anesthetics in remote locations.

Regarding emergency surgical rescue airway management, Dr. Larson recently published a Letter to the Editor in the American Society of Anesthesiologists Newsletter, February 2014, entitled, Ditch the Needle – Teach the Knife. In this letter, Dr. Larson wrote:

“in life-threatening airway obstruction, … an emergency cricothyrotomy is much quicker, easier, safer and more effective than any needle-based technique. I can state with confidence that there is no place in emergency airway management for needle-based attempts to establish ventilation. It should be deleted from the ASA Difficult Airway Algorithm. I have participated in seven cricothyrotomies in emergency airway situations, and all of the patients left the hospital without any neurological injury or complications from the cricothyrotomy. The risk-benefit ratio is markedly in favor the knife technique…. With a knife, or scissors, one cuts quickly either vertically or horizontally below the thyroid cartilage and there is the cricothyroid membrane or tracheal rings. The knife is inserted into the trachea and turned 90 degrees, and an airway is established. At that point, a small tube of any type can be inserted next to the knife. The knife technique is much safer because there is virtually nothing that one can harm by making an incision within two inches or less in the midline of the neck, and it can be performed in less than 30 seconds. In contrast, the needle is fraught with complications, including identifying the trachea, making certain that the needle is entirely in the trachea and does not move ( to avoid subcutaneous emphysema when an oxygen source is established), establishing a pressurized oxygen delivery system (which will take more than five minutes even in the most experienced circumstances), and avoiding causing a tension pneumothorax… I know of multiple cases of acute airway obstruction where the needle technique was attempted, and in all cases the patients died. I know of no such cases when a cricothyrotomy was used as the primary treatment of acute airway obstruction.”

A final note on the awake intubation of patients with a difficult airway: In hindsight in any difficult airway case, one often wishes they had secured an endotracheal tube prior to the induction of general anesthesia. The difficult problem is deciding prior to a case which patient has such a difficult airway that the induction of general anesthesia should be delayed until after intubation. In anesthesia oral board examinations it may be wise to say you would perform an awake intubation on a difficult airway patient rather than risk the “can’t intubate, can’t ventilate” scenario the examiner is probably poised to skewer you with. In medical malpractice lawsuits, plaintiff expert witnesses in anesthesia airway disaster cases often testify that a brain-dead patient’s life would have been saved if only the anesthesiologist had performed awake intubation rather than inducing general anesthesia first and then losing the airway. The key question is: how does one decide which patient needs an awake intubation? As an anesthesia practitioner, if you performed awake intubations on one out of 50 cases because you were worried about a difficult airway, you would delay operating rooms and surgeons multiple times per year because of your caution. You will not be popular if you do this. In my clinical practice and in the practice of the excellent Stanford anesthesiologists I work with, the prevalence of awake intubation is very low. I estimate most anesthesiologists perform between zero and two awake intubations per year. The most common indications include patients with severe ankylosing spondylitis of the cervical spine, congenital airway anomalies, and severe morbid obesity. Dr. Larson wrote in his Letter to the Editor of the Stanford Gas Pipeline in May, 2013, “I do anesthesia for most of the patients with complex head and neck tumors, and I find fewer and fewer indications for awake fiberoptic intubation. As long as the lungs can be ventilated by bag-mask or LMA, which is true for almost all sedated patients, Plan C is easier, quicker and safer than awake fiberoptic intubation both for the patient and the anesthesia provider.  In experienced hands, Plan C can be completed in less than 5 minutes, and one can become proficient by practicing in normal patients. I have done hundreds of Plan C’s, many under difficult circumstances, without a single failure or complication.  Obviously, no technique will encompass every conceivable airway problem, but mastering Plans A-D and awake oral and nasal fiberoptic intubation will meet the needs of anesthesia providers in almost all circumstances.”

May you never experience the  emotional trauma of an airway disaster. Become an expert in bag-mask ventilation, always have access to a video laryngoscope or an Airtraq, and consider  Dr. Larson’s  Plan A-D system, described in detail in the Appendix on airway management and intubation in the newest edition of Anesthesiologists Manual of Surgical Procedures by Richard Jaffe et al (Lippincott Williams and Wilkins, 5th Edition, May 2014).

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

OBAMACARE AND ANESTHESIA

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

THE ANESTHESIA CONSULTANT

Key questions in our specialty in 2014 related to Obamacare and anesthesia. This article was originally published in 2014, when Barack Obama was the President of the United States. A key question in our specialty at that time was “How will ObamaCare affect anesthesiology?” The following essay represents my thoughts as of 2014, prior to the Trump presidency.

I don’t have a crystal ball, but based on what I’ve read, what I’ve observed, and what I’m hearing from other physicians, these are my predictions on how ObamaCare will change anesthesia practice in the United States:

  1. There will be more patients waiting for surgery. Millions of new patients will have ObamaCare cards and coverage. A flawed premise of ObamaCare is that a system can cover more patients and yet spend less money.
  2. Reimbursement rates will be lower. How many anesthesiologists will sign up for Medicaid or Medicare-equivalent rates to care for patients? Large organizations such as university hospitals, Kaiser, Sutter, and other HMO-types will likely sign up for the best rate they can negotiate. As a result, their physicians will have increased patient numbers and lower reimbursement for their time. The insurance plans that patients purchase will have higher deductibles, and most patients will have to pay more out of pocket for their surgery and anesthesia. This will lead to patients delaying surgery, and shopping around to find the best value for their healthcare dollar.
  3. Less old anesthesiologists. Older anesthesiologists will retire early rather than work for markedly reduced pay.
  4. Less young anesthesiologists. The pipeline of new, young anesthesiologists will slow. Young men and women are unlikely to sign up for 4 years of medical school,  4 – 6 years of residency and fellowship, and an average of $150,000 of student debt if their income incentives are severely cut by ObamaCare.
  5. More certified nurse anesthetists (CRNAs). It seems apparent that ObamaCare is interested in employing cheaper providers of medical services. CRNAs will command lower salaries than anesthesiologists. The premise to be tested is whether CRNAs can provide the same care for less money. Expect to see wider use of anesthesia care teams and of independent CRNA practice. Expect the overall quality of anesthesia care to change as more CRNAs and less M.D.’s are employed.
  6. A two-tiered system. Anesthesiologists who have a choice will not sign up for reduced ObamaCare rates of reimbursement. Surgeons who have a choice will not sign up for reduced ObamaCare reimbursement. Expect a second tier of private pay medical care to exist, where patients will choose non-ObamaCare M.D.’s of their choice, and will pay these physicians whatever the physicians charge. This tier will provide higher service and shorter waiting times before surgery is performed. This tier will likely be populated by some of the finest surgeons–surgeons are unwilling to work for decreased wages. A subset of anesthesiologists will work in this upper tier of medical care, and these anesthesiologists will earn higher wages as a result.
  7. Will the Accountable Care Organization (ACO) model stumble as the Health Maintenance Organization (HMO) model did in the 1990’s? ObamaCare provides for the existence of ACO’s, which are hospital-physician entities designed to provide comprehensive health care to patients in return for bundled payments. In this model the surgeon, the anesthesiologist, and the hospital (i.e. nurses, pharmacy, and the medical device industry) will divide up the bundled surgical payment. In this model it’s essential that an anesthesiologist leader has a strong presence at the negotiating table. A worrisome issue with the ACO model, as it was with the HMO model, is the flow of money. Physicians will no longer be working for their patients, but will be working for the ACO. The  primary incentive will be to be paid by the ACO, rather than to provide the best care possible.
  8. Anesthesia leadership skills will change. The physician leader of each anesthesia group must be a powerful and effective politician and economic strategist. These traits are not taught during anesthesia residency, and these traits have nothing to do with being an outstanding clinician.
  9. What about the Perioperative Surgical Home (PSH)? The American Society of Anesthesiologists is proposing the model of the PSH, in which anesthesiologists will assume leadership roles managing patient care in the preoperative, intraoperative, and postoperative arenas. This is a desirable goal for our specialty. No physician is better equipped than an anesthesiologist to supervise patients safely through the perioperative period with the highest standards of quality and cost-control. The Perioperative Surgical Home is designed to work with the model of the Accountable Care Organization. How these systems of the Perioperative Surgical Home and the Accountable Care Organization will evolve remains to be seen. It will be the role for individual anesthesia physician leaders in each hospital to seize the new opportunities.  Rank and file anesthesiologists will likely follow their leadership.

10. Consolidation of anesthesia groups. Small anesthesia groups will likely merge into bigger groups in an effort dominate a clinical census, and therefore to negotiate higher reimbursement rates. In November, 2013, the 100-physician Medical Anesthesia Consultants Medical Group, Inc, of San Ramon, California was acquired by Sheridan Healthcare Inc, a 2,500-physician services company based in Florida. Per Sheridan’s CEO, John Carlyle, the acquisition “provides a platform that will accelerate our expansion in the California marketplace.” This was the largest merger in Northern California anesthesia history.

11. Requirement of more anesthesia clinical metrics. Government and insurance payors will require more metrics to document that the provided clinical care was excellence. A typical required metric may be a high percentage of patients who received preoperative antibiotics prior to incision, or a low percentage of patients free from postoperative nausea and vomiting. Each anesthesia groups will need to establish computerized data-capturing systems to present this information to payors. The effort to tabulate these metrics will be another incentive for anesthesia groups to merge into larger clinical entities.

In summary:  More patients, more cases, less money, more bureaucracy, less money, more CRNA providers, and less money. These are the challenges ObamaCare presents to anesthesiologists. Stay tuned. Legions of patients with ObamaCare cards will be knocking on hospital doors. The government is expecting enough anesthesiologists to sign up for ObamaCare contracts to make the new system successful. It’s impossible to tell what behaviors ObamaCare will incentivize. Each anesthesiologist has the benefit of 25+ years of education, and each anesthesiologist will make intelligent choices regarding their career and their time.

Bob Dylan once sang, “I ain’t gonna work on Maggie’s Farm no more.”

Time will tell if ObamaCare is Maggie’s Farm for physicians.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

HOW DOES A HEROIN OVERDOSE KILL? AN ANESTHESIOLOGIST’S VIEW

THE ANESTHESIA CONSULTANT


On February 2, 2014, Academy Award-winning actor Phillip Seymour Hoffmann was found dead with a needle in his arm and syringes and packets of heroin in his room. How does a heroin overdose kill a person?

 phillip seymour hoffman heroin overdose

Anesthesiologists are uniquely qualified to answer this question. Anesthesiologists administer intravenous narcotics every day, because narcotics are important pain-relieving drugs in anesthetic care. If an anesthesiologist is attending to you while narcotics are injected into your bloodstream, you are safe. If an addicts chooses to inject narcotics into his or her bloodstream while they are alone in their apartment, they can die.

Heroin (diacetylmorphine or morphine diacetate) is in the same category of drugs as morphine, Demerol, and fentanyl. Heroin is prescribed as a controlled drug in the United Kingdom for use as a potent analgesic or pain reliever, but the drug is not approved for any medical use in the United States.

Within minutes, injected heroin crosses from the bloodstream to the brain. Once inside the brain, heroin is metabolized to the active drug 6-monoacetylmorphine (6-MAM), and then to morphine. Each of these chemicals binds to opioid receptors in the brain, which results in heroin’s euphoric, pain relieving, and anxiety-relieving effects. The duration of a single dose of heroin is 3-4 hours.

In addition to sensations of euphoria, calmness, sleepiness, pain relief, and blunting of anxiety, narcotics cause significant decrease in both the rate of breathing and the depth of each breath. This respiratory depression can be lethal, especially at higher doses.

In all acute care medicine, whether in the operating room, the intensive care unit, the emergency room, or the battlefield, physicians follow the mantra of “Airway-Breathing-Circulation.” A doctor’s first priority to keep the upper airway open, using a variety of techniques including jaw thrusts, extending the neck, inserting an oral airway, or placement of a breathing tube.  A doctor’s second priority is to assure that breathing, or ventilation, is ongoing. The doctor may assist breathing by delivering breaths of oxygen into the patient’s lungs via a ventilation bag (e.g. an Ambu bag). A doctor’s third priority is to assure that adequate circulation, or heart function, is ongoing.

If a large dose of narcotic is administered, breathing may cease or become so obstructed by the tongue and soft palate that no air moves in and out through the lungs. If an addict injects heroin while alone in their home, and they lose consciousness, their airway may become obstructed and breathing may cease. Oxygen levels to the brain and heart will plummet. After only minutes of inadequate oxygen, their heart will arrest and the addict will die.

Simultaneous usage of additional central nervous system depressant drugs, such as alcohol, benzodiazepines (Xanax, Valium, Librium, Ativan), or narcotic pills (oxycodone, Vicodin, Percocet) along with heroin can intensify the respiratory depression, and place the addict at even higher risk of ineffective breathing and resultant cardiac arrest.

Tolerance to heroin develops quickly, and users require more of the drug to achieve the same effects. This prompts addicts to inject increasing doses to achieve the desired “high,” with the attendant risk that each increased dose will be excessive, and lead to airway obstruction, inadequate breathing, and cardiac arrest.

Intravenous heroin usage carries additional risks, including viral infection (hepatitis or AIDS) from contaminated needles, bacterial infection of the heart valves (bacterial endocarditis), reactions to contaminants (e.g. starch, talc, or other drugs) in the heroin preparation, localized infections (abscesses) at the site of injection, and powerful withdrawal symptoms on cessation of heroin use.

But cardiac arrest from respiratory depression looms as the most frequent cause of sudden death in heroin addicts.

JANUARY 2014 LETHAL INJECTION WITH MIDAZOLAM AND HYDROMORPHONE … AN ANESTHESIOLOGIST’S OPINION

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.
emailrjnov@yahoo.com
THE ANESTHESIA CONSULTANT

On January 16, 2014, the New York Times reported that Dennis McGuire was executed by a lethal  injection of midazolam and hydromorphone. McGuire was previously convicted of the 1994 rape and murder of a 22-year-old pregnant woman.

 

The lethal injection occurred at the Southern Ohio Correctional Facility in Lucasville, Ohio. It was the first time any state used the combination of midazolam and hydromorphone for an execution. It was reported that McGuire took 15 minutes to die. A reporter who witnessed the execution described McGuire as struggling, gasping loudly, snorting and making choking noises for nearly 10 minutes before falling silent and being declared dead a few minutes later.

What happens to a human when you inject midazolam and hydromorphone? Anesthesiologists use these drugs every day to provide safe anesthesia care in operating rooms.

Midazolam (Versed) is a benzodiazepine, a drug commonly given immediately prior to surgery to relieve a patient’s anxiety. A typical adult dose is 2 mg. Midazolam is also commonly used for conscious sedation for colonoscopy procedures, when repeated 1 – 2 mg doses are titrated for relaxation.

Hydromorphone (Dilaudid) is a narcotic similar to morphine. Physicians inject Dilaudid to relieve pain. A typical adult intravenous dose is 0.2 mg. Doses may be repeated and titrated to effect if the patient continues to hurt.

Both midazolam and hydromorphone are respiratory depressants. When administered together in high doses, these two drugs will (1) cause unconsciousness, and (2) depress breathing, and perhaps cause breathing to cease if the doses are high enough.

When anesthesiologists inject doses of midazolam and hydromorphone we routinely administer supplemental oxygen, and monitor the patient with a pulse oximeter, an ECG machine, an end-tidal carbon dioxide monitor and a blood pressure cuffs. Anesthesiologists give moderate doses of midazolam and hydromorphone safely every day.

Can you kill someone with mega-doses of these two drugs? Absolutely. I have no idea what doses were used in the Ohio execution, but let’s assume an executioner administered massive overdoses in the range of 50 mg of midazolam and 5 mg of hydromorphone. The mechanism of death would be hypoventilation and hypoxia. In layman’s terms this means the patient’s ventilation will decrease markedly, and because of this decreased breathing the patient’s oxygen level will decrease. If the oxygen level decreases to a lethal level–a level low enough that the heart and brain will have inadequate oxygen–the patient will have a cardiac arrest. Can 10 -15 minutes pass by before the inadequate oxygen levels cause cardiac arrest? Yes, they could.

Would a patient dying in this fashion suffer? No, it’s unlikely they will suffer. If the doses of midazolam and hydromorphone are large enough, the patient will be unconscious before and during their cardiac death.

Will an anesthesiologist ever supervise such a lethal injection on death row? No. Per my earlier blog entry, ANESTHESIA FACTS FOR NONMEDICAL PEOPLE: LETHAL INJECTION AND THE ANESTHESIOLOGIST, listed in the column at your right, no anesthesiologist will ever use his or her skills to end a human’s life.

State governments will have to find someone else to supervise lethal injections. An anesthesia doctor’s job is to keep patients alive.

THE TOP 11 DISCOVERIES IN THE HISTORY OF ANESTHESIA

THE ANESTHESIA CONSULTANT

Important advances in the history of anesthesia changed the specialty forever. Humans have inhabited the Earth for 200,000 years, yet the discovery of surgical anesthesia was a recent development in 1846. For thousands of years most surgical procedures were accompanied by severe pain. The only strategies available to blunt pain were to give patients alcohol or opium until they were stuporous.

In the 21st Century, modern anesthesiologists utilize dozens of medications and apply sophisticated high-tech medical equipment. How did our specialty advance from prescribing patients two shots of whiskey to administering modern anesthetics?

In chronologic order, my choices for the 11 most important advances in the history of anesthesia follow below. I’ve included comments to expound on the impact of each discovery.

image069

1846. THE DISCOVERY OF ETHER AS A GENERAL ANESTHETIC. The first public demonstration of general anesthesia occurred at Harvard’s Massachusetts General Hospital in Boston, Massachusetts. Dr. William Morton, a local dentist, utilized inhaled ether to anesthetize patient Edward Abott.  Dr. John Warren then painlessly removed a tumor from Abbott’s neck.  Comment: This was the landmark discovery. From this point forward, painless surgery became possible.

1885. THE DISCOVERY OF INJECTABLE COCAINE AND LOCAL ANESTHESIA.  Cocaine was the first local anesthetic. Dr. William Halsted of Johns Hopkins University in Baltimore first injected 4% cocaine into a patient’s forearm and concluded that cocaine blocked sensation, as the arm was numb below but not above the point of injection. The first spinal anesthetic was performed in 1885 when Dr. Leonard Corning of Germany injected cocaine between the vertebrae of a 45-year-old man and caused numbness of the patient’s legs and lower abdomen. Comment: The discovery of local anesthesia gave doctors the power to block pain in specific locations. Improved local anesthetics procaine (Novocain) and lidocaine were later discovered in 1905 and 1948, respectively.

1896. THE DISCOVERY OF THE HYPODERMIC NEEDLE, THE SYRINGE, AND THE INJECTION OF MORPHINE. Alexander Wood of Scotland invented a hollow needle that fit on the end of a piston-style syringe, and used the syringe and needle combination to successfully treat pain by injections of morphine. Comment: The majority of anesthetic drugs today are injected intravenously. Such injections would be impossible without the invention of the syringe.

1905. DISCOVERY OF THE MEASUREMENT OF BLOOD PRESSURE BY BLOOD PRESSURE CUFF. Dr. Nikolai Korotkov of Russia described the sounds produced during auscultation with a stethoscope over a distal portion of an artery as a blood pressure cuff was deflated. These Korotkoff sounds resulted in an accurate determination of systolic and diastolic blood pressure. Comment: Anesthesiologists monitor patients repeatedly during every surgery. A patient’s vital signs are the heart rate, respiratory rate, blood pressure, and temperature. It would be impossible to administer safe anesthesia without blood pressure measurement. Low blood pressures may be evidence of anesthetic overdose, excessive bleeding, or heart dysfunction. High blood pressures may be evidence of inadequate anesthetic depth, or uncontrolled hypertensive heart disease.

1913. DISCOVERY OF THE CUFFED ENDOTRACHEAL BREATHING TUBE. Sir Ivan Magill of England developed a technique of placing a breathing tube into the windpipe, and endotracheal anesthesia was born. Dr. Chevalier Jackson of Pennsylvania developed the first laryngoscope used to visualize the larynx and insert an endotracheal tube. Drs. Arthur Guedel and Ralph Waters at the University of Wisconsin discovered the cuffed endotracheal tube in 1928. This advance allowed the use of positive-pressure ventilation into a patient’s lungs. Comment: Surgery within the abdomen and chest would be impossible without controlling the airway and breathing with a tube in the trachea. As well, the critical care resuscitation mantra of Airway-Breathing-Circulation would be impossible without an endotracheal tube.

1934. THE DISCOVER OF THIOPENTAL AND INJECTABLE BARBITURATES. Dr. John Lundy of the Mayo Clinic in Rochester, Minnesota introduced the intravenous anesthetic sodium thiopental into anesthetic practice. Injecting Pentothal became the standard means to induce general anesthesia. Pentothal provided a more pleasant method of going to sleep than inhaling pungent ether. Comment: This was a huge breakthrough. Almost every modern anesthetic begins with the intravenous injection of an anesthetic drug. (Propofol has now replaced Pentothal)

1940. THE DISCOVERY OF CURARE AND INJECTABLE MUSCLE RELAXANTS. Dr. Harold Griffith of Montreal, Canada injected the paralyzing drug curare during general anesthesia to induce muscular relaxation requested by his surgeon. Although the existence of curare was known for many years (it was an arrow poison of the South American Indians), it was not used in surgery to deliberately cause muscle relaxation until this time. Comment: Paralyzing drugs are necessary to enable the easy insertion of endotracheal tubes into anesthetized patients, and paralysis is also essential for many abdominal and chest surgeries.

1950’s. THE DEVELOPMENT OF THE POST-ANESTHESIA CARE UNIT (PACU) AND THE INTENSIVE CARE UNIT (ICU). The shock and resuscitation units organized during World War II and the Korean War resulted in efficient care for the sick and wounded. After the wars, PACU’s and ICU’s were natural extensions of these battlefield inventions. Comment: In the PACU, a patient’s airway, breathing, and circulation are observed, monitored, and treated immediately following surgery. PACU’s decrease post-operative complications. In the ICU, Airway-Breathing-Circulation management perfected in the operating room is extended to critically ill patients who are not undergoing surgery.

1956. THE DISCOVERY OF HALOTHANE, THE FIRST MODERN INHALED ANESTHETIC. British chemist Charles Suckling synthesized the inhaled anesthetic halothane. Halothane had significant advantages over ether because of halothane’s more pleasant odor, higher potency, faster onset, nonflammability, and low toxicity. Halothane gradually replaced older anesthetic vapors, and achieved worldwide acceptance. Comment: Halothane was the forerunner of isoflurane, desflurane, and sevoflurane, our modern inhaled anesthetics. These drugs have faster onset and offset, cause less nausea, and are not explosive like ether. The discovery of halothane changed inhalation anesthesia forever.

1983. THE DISCOVERY OF PULSE OXIMETRY MONITORING. The Nellcor pulse oximeter, co-developed by Stanford anesthesiologist Dr. William New, was the first commercially available device to measure the oxygen saturation in a patient’s bloodstream. The Nellcor pulse oximeter had the unique feature of lowering the audible pitch of the pulse tone as saturation dropped, giving anesthesiologists a warning that their patient’s heart and brain were in danger of low oxygen levels. Comment: The Nellcor changed patient monitoring forever. Oxygen saturation is now monitored before, during, and after surgery. Prior to Nellcor monitoring, the first sign of low oxygen levels was often a cardiac arrest. Following the invention of the Nellcor, oxygen saturation became the fifth vital sign, along with pulse rate, respiratory rate, blood pressure, and temperature.

1986.  END-TIDAL CO2 MONITORING. In 1986 the American Society of Anesthesiologists mandated continual end-tidal carbon dioxide analysis be performed using a quantitative method such as capnography, from the time of endotracheal tube/laryngeal mask placement until extubation/removal or initiating transfer to a postoperative care location. The detection and monitoring of carbon dioxide gave immediate feedback whenever ventilation of the lungs was failing. For example, an endotracheal breathing tube placed in the esophagus instead of the tracheal would yield zero (or close to zero) carbon dioxide. The end-tidal CO2 device alarms immediately, the anesthesiologist recognizes the problem, and fixes it at once. The development of pulse oximetry and end-tidal CO2 monitoring were concurrent, and because of these twin discoveries, anesthesia care became markedly safer after the 1980’s

These are the top 11 discoveries in the history of anesthesia as I see them. What will be the next successful invention to advance our specialty?  A superior pain-relieving drug? A better inhaled anesthetic? An improved monitor to insure patient safety? Top scientists and physicians worldwide are working this very day to join this list. Good luck to each of them.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

HOW RISKY IS A TONSILLECTOMY?

THE ANESTHESIA CONSULTANT

13-year-old Jahi McMath of Oakland, California suffered sudden bleeding from her nose and mouth and cardiac arrest following a December 9th 2013 tonsillectomy, a surgery intended to help treat her obstructive sleep apnea. After the bleeding she lapsed into a coma. Three days later she was declared brain-dead.

tonsillectomy-recovery-day-by-day-12

How could this happen?

Behind circumcision and ear tubes, tonsillectomy is the third most common surgical procedure performed on children in the United States. 530,000 tonsillectomies are performed children under the age of 15 each year. Tonsillectomy is not a minor procedure. It involves airway surgery, often in a small child, and often in a child with obstructive sleep apnea. The surgery involves a risk of bleeding into the airway. The published mortality associated with tonsillectomy ranges from 1:12,000 to 1:40,000. 

Between 1915 and the 1960’s, tonsillectomy was the most common surgery in the United States, done largely to treat chronic throat infections. After the 1970’s, the incidence of tonsillectomies dropped, as pediatricians realized the procedure had limited success in treating chronic throat infections. The number of tonsillectomies has increased again in the last thirty years, as a treatment for obstructive sleep apnea (OSA). Currently 90 percent of tonsillectomies are performed to treat OSA. Only 1 – 4 % of children have OSA, but many of these children exhibit behavioral problems such as growth retardation, poor school performance, or daytime fatigue. The American Academy of Otolaryngology concluded that “a growing body of evidence indicates that tonsillectomy is an effective treatment for sleep apnea.”

Tonsillar and adenoid hypertrophy are the most common causes of sleep-disordered breathing in children. Obstructive sleep apnea is defined as a “disorder of breathing during sleep characterized by prolonged upper airway obstruction and/or intermittent complete obstruction that disrupts normal ventilation during sleep.” (Miller’s Anesthesia, 7th edition, 2009, Chapter 82).

In OSA patients, enlarged tonsils can exacerbate loud snoring, decrease oxygen levels, and cause obstruction to breathing. Removal of the tonsils can improve the diameter of the breathing passageway. Specific diagnosis of OSA can be made with an overnight sleep study (polysomnography), but applying this test to large populations of children is a significant expense. Currently only about 10 percent of otolaryngologists request a sleep study in children with sleep-disordered breathing prior to surgery (Laryngoscope 2006;116(6):956-958). In our surgical practice in Northern California, most pediatricians and otolaryngologists forego the preoperative overnight sleep study if the patient has symptoms of obstructed sleep, confirmed by a physical exam that reveals markedly enlarged tonsils.

Every tonsillectomy requires general anesthesia, and anesthesiologists become experts in the care of tonsillectomy patients. Prior to surgery the anesthesiologist will review the chart, interview the parent(s), and examine the child’s airway. Most children under the age of 10 will be anesthetized by breathing sevoflurane via an anesthesia mask, which is held by the anesthesiologist. Following the child’s loss of consciousness, the anesthesiologist will place an intravenous (IV) catheter in the child’s arm. The anesthesiologist then inserts a breathing tube into the child’s windpipe, and turns the operating table 90 degrees away so the surgeon has access to operate on the throat. The surgeon will move the breathing tube to the left and right sides of the mouth while he or she removes the right and left tonsils. (note: children older than the age of 10 will usually accept an awake placement of an IV by the anesthesiologist, and anesthetic induction is accomplished by the IV injection of sleep drugs including midazolam and propofol, rather than by breathing sevoflurane via an anesthesia mask).

The child remains asleep until the tonsils are removed, and all bleeding from the surgical site is controlled. The anesthesiologist then discontinues general anesthetic drugs and removes the breathing tube when the child awakens. Care is taken to assure that the airway is open and that breathing is adequate. Oxygen is administered until the child is alert. Tonsillectomy is painful, and intravenous opioid drugs such as fentanyl or morphine are commonly administered to relieve pain. The opioids depress respiration, and monitoring of oxygen levels and breathing is routinely done until the child leaves the surgical facility.

Most tonsillectomy patients have surgery as an outpatient and are discharged home within hours after surgery. Prior to the 1960’s patients were hospitalized overnight routinely post-tonsillectomy. In 1968 a case series of 40,000 outpatient tonsillectomies with no deaths was reported, and performance of tonsillectomy on an outpatient basis became routine after that time. (Miller’s Anesthesia, 7th edition, 2009, Chapter 33).

Published risk factors for postoperative complications after tonsillectomy include: (1) age younger than 3 years; (2) evidence of OSA; (3) other systemic disorders of the heart and lungs); (4) presence of airway abnormalities; (5) bleeding abnormities; and (6) living a long distance from an adequate health care facility, adverse weather conditions, or home conditions not consistent with close observation, cooperativeness, and ability to return quickly to the hospital. (Miller’s Anesthesia, 7th edition, 2009, Chapter 82).

The incidence of post-tonsillectomy bleeding increases with age. In a national audit of more than 33,000 tonsillectomies, hemorrhage rates were 1.9% in children younger than 5 years old, 3% in children 5 to 15 years old, and 4.9% in individuals older than 16. The return to the operating room rate was 0.8% in children younger than 5 years old, 0.8% in children 5 to 15 years old, and 1.2% in individuals older than 16. (Miller’s Anesthesia, 7th edition, 2009, Chapter 75).

Primary bleeds usually occur within 6 hours of surgery. Hemorrhage is usually from a venous or capillary bleed, rather than from an artery. Complications occur because of hypovolemia (massive blood loss), the risk of blood aspiration into the lungs, or difficulty with replacing the breathing tube should emergency resuscitation be necessary. Early blood loss can be difficult to diagnose, as the blood is swallowed and not seen. Signs suggesting hemorrhage are an unexplained increasing heart rate, excessive swallowing, pale skin color, restlessness, sweating, and swelling of the airway causing obstruction. Low blood pressure is a late feature. (Miller’s Anesthesia, 7th edition, 2009, Chapter 75).

What happened to 13-year-old Jahi McMath in Oakland following her tonsillectomy? We have no access to her medical records, and all we know is what was reported to the press. The following text was published in the 12/21/2013 Huffington Post:

After her daughter underwent a supposedly routine tonsillectomy and was moved to a recovery room, Nailah Winkfield began to fear something was going horribly wrong.

Jahi was sitting up in bed, her hospital gown bloody, and holding a pink cup full of blood.

“Is this normal?” Winkfield repeatedly asked nurses.

With her family and hospital staff trying to help and comfort her, Jahi kept bleeding profusely for the next few hours then went into cardiac arrest, her mother said.

Despite the family’s description of the surgery as routine, the hospital said in a memorandum presented to the court Friday that the procedure was a “complicated” one.

“Ms. McMath is dead and cannot be brought back to life,” the hospital said in the memo, adding: “Children’s is under no legal obligation to provide medical or other intervention for a deceased person.”

In an interview at Children’s Hospital Oakland on Thursday night, Winkfield described the nightmarish turn of events after her daughter underwent tonsil removal surgery to help with her sleep apnea.

She said that even before the surgery, her daughter had expressed fears that she wouldn’t wake up after the operation. To everyone’s relief, she appeared alert, was talking and even ate a Popsicle afterward.

But about a half-hour later, shortly after the girl was taken to the intensive care unit, she began bleeding from her mouth and nose despite efforts by hospital staff and her family.

While the bleeding continued, Jahi wrote her mother notes. In one, the girl asked to have her nose wiped because she felt it running. Her mother said she didn’t want to scare her daughter by saying it was blood.

Family members said there were containers of Jahi’s blood in the room, and hospital staff members were providing transfusions to counteract the blood loss.

“I don’t know what a tonsillectomy is supposed to look like after you have it, but that blood was un-normal for anything,” Winkfield said.

The family said hospital officials told them in a meeting Thursday that they want to take the girl off life support quickly.

“I just looked at the doctor to his face and I told him you better not touch her,” Winkfield recalled.

Despite the family’s description of the surgery as routine, the hospital said in a memorandum presented to the court Friday that the procedure was a “complicated” one.

 

Despite the precaution of hospitalizing Jahi McMath post-tonsillectomy, when her bleeding developed it seems the management of her Airway-Breathing-Circulation did not go well. I’ve attended to bleeding post-tonsillectomy patients, and it can be a harrowing experience. It can be an extreme challenge to see through the blood, past the swollen throat tissues post-surgery, and locate the opening to the windpipe so that one can insert the breathing tube needed to supply oxygen to the lungs. Assistance from a second anesthesiologist is often needed. The surgeon will be unable to treat or control severe bleeding until an airway tube is in place.  Difficult intubation and airway management can lead to decreased oxygen levels and ventilation, jeopardizing oxygen delivery to the brain and heart. If severe bleeding is unchecked and transfusion of blood cannot be applied swiftly, the resulting low blood pressure and shock can contribute to the lack of oxygen to a patient’s brain.

A bleeding tonsillectomy patient can be an anesthesiologist’s nightmare.

READING IN THE OPERATING ROOM

THE ANESTHESIA CONSULTANT

You’re an attending anesthesiologist. You enter another colleague’s operating room to give him a bathroom break during his 6-hour plastic surgery case, and you find him tapping on an iPad and reading in the operating room. What do you do?

Discussion:  Is it OK for the anesthesiologist to be reading in the operating room? Is it OK for him to be referencing the Internet? Answering email? Sending text messages on his smartphone? Or should that anesthesiologist be staring transfixed at the monitor screen for hour after hour, maintaining flawless vigilance?

In the Anesthesia Patient Safety Foundation Newsletter Summer 1995 edition, Dr. Matthew Weinger discussed the issue of reading in the operating room. He emphasized that there were no scientific data on the impact of reading on anesthesia provider vigilance or task performance. He cited data that anesthesiologists are ‘idle’ during 40% of routine cases. He asserted that “anesthesia providers read during these idle periods to prevent boredom, and that boredom was a problem of information underload, insufficient work challenge, and under-stimulation…Adding tasks to a monotonous job may decrease boredom and dividing attention among several tasks (time-sharing) may, in some circumstances, actually improve monitoring performance.” Weinger concluded that, “in the absence of controlled studies on the effect of reading in the operating room on anesthesia vigilance and task performance, no definitive or generalizable recommendations can be made. The decision must remain a personal one based on recognition of one’s capabilities and limitations. From a broader perspective, the anesthesia task including associated equipment must be optimized to minimize boredom and yet not be so continuously busy as to be stressful.”

In the Anesthesia Patient Safety Foundation Newsletter, Fall 2004 edition, Dr. Terri Monk opined that reading in the OR seriously compromised patient safety. She was opposed to reading for the following reasons:

  1. Reading diverts one’s attention from the patient.
  2. The patient is paying for the anesthesiologist’s undivided attention, and most well-informed patients want to know if the anesthesiologist plans to turn over a portion of their anesthesia care to a nurse or resident. If we are obliged to honestly answer that concern, then, shouldn’t we also be obliged to inform the patient that we plan to read during a portion of the anesthetic?
  3. Reading is medico-legally dangerous. Dr. Monk wrote, “Any plaintiff’s attorney would love to have a case in which the circulating nurse would testify, ‘Dr. Giesecke was reading when the cardiac arrest occurred. Yep, he was reading the Wall Street Journal. You know he has a lot of valuable stocks that he must keep track of.’ It is possible that if anesthesiologists informed their malpractice carriers that they routinely read during cases, the companies might raise premiums or cancel malpractice coverage.”
  4. The practice of reading in the OR projects a negative public image. Nurses, technicians, and surgeons may think the anesthesiologist is less professional.

A 2009 study looked at 172 selected general anesthetic cases in an academic medical center. Vigilance was assessed by the response time to a randomly illuminated alarm light. Reading was observed in 35% of cases. In the 60 cases that involved reading, providers read during 25  +/- 3% of maintenance time but not during induction or emergence. Vigilance to the alarm light was no different between readers and non-readers.

Miller’s Anesthesia (7th Edition, 2009, chapter 6) states, “Although it is indisputable that reading can distract attention from patient care, there are no data at present to determine the degree to which reading does distract attention, especially if the practice is confined to low-workload portions of a case. Furthermore, many anesthetists pointed out that reading as a distraction is not necessarily any different from many other kinds of activities not related to patient care that are routinely accepted, such as idle conversation among personnel.”

A 2012 study concluded there were no data concerning the effects of the use of laptops and smartphones in the operating theatre on anesthetist performance, and that these devices were now in frequent use. They discussed the use of laptops and smartphones in regards to the two pertinent issues of vigilance and multitasking. There were data that in some circumstances the addition of a secondary task (i.e. using a laptop or smartphone) during periods of low stimulation can improve vigilance and overall task performance, but the workload and the nature of the secondary task were critical. The authors made the following points regarding the nature of anesthesia work and the factors that affect performance in anesthesia:

  1. Anesthesia involves multi-tasking and the maintenance of situational awareness. Studies have shown that attending to a range of tasks simultaneously is a key characteristic of anesthetic practice, and that anesthetists are superior to non-anesthetists in performing additional tasks while monitoring patients.
  2. Anesthetists typically only glance at monitors. Covert observations of anesthetists in British Columbia revealed subjects spent less than 5% of their time observing the monitoring display. This was made up of brief glances (1.5 to 2 seconds duration) occurring 15 – 20 times during each 10-minute segment of time.
  3.    Anesthetic work is reduced during prolonged maintenance, potentially resulting in boredom and/or secondary activities being undertaken. The maintenance phase in some anesthetics (typically cases of longer duration, lower complexity and where the patient is stable) may be a time of low workload and infrequent task demands. In a study of 105 anesthesia clinicians, half reported being bored infrequently, but 90% admitted to occasional episodes of extreme boredom. Boredom can result in severely decreased vigilance if the anesthetist is suffering from sleep deprivation.
  4.    The authors concluded there was no evidence to support a blanket prohibition on the use of smartphones and laptops in the operating theatre, and there was good reason to avoid edicts that are not supported by solid evidence. They stated, “There is no doubt that reading or computer usage gives the appearance of being less attentive, even if there are no measurable effects on routine care…Computer and phone tasks that also require immediate responses appear to provide a greater risk than reading (whether from a book or screen). While boredom may be cognitively unpleasant, there is no evidence of anesthetist boredom (in the absence of sleep) harming patients.”

I recently attended the American Society of Anesthesiologists national convention in San Francisco. At the conclusion of the meeting, the ASA emailed me a full text edition of the Refresher Course lectures as an email attachment, in a format designed to be downloaded onto a computer. Like myself, more than 10,000 anesthesiologist attendees of the ASA meeting will now have access to the Refresher Course curriculum on their laptops or iPads. Will some of them read these Refresher Courses during the stable maintenance phases of anesthetics in their operating rooms? Perhaps.

Returning to the Clinical Case for Discussion above, what will you do about your colleague you discovered using his iPad in the operating room? My guess is, based on what has been published in the anesthesia literature, you’ll give him the bathroom break as intended, and say nothing about his use of the iPad in the operating room.

HOW TO WAKE UP PATIENTS PROMPTLY FOLLOWING GENERAL ANESTHETICS

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Two patients arrive simultaneously in the recovery room following general endotracheal anesthetics. One patient is unresponsive and requires an oral airway to maintain adequate respiration. In the next bed, the second patient is awake, comfortable and conversant. How can this be? It occurs because different anesthetists practice differently. Some can wake up patients promptly, and some cannot.

Aldrete Score Calculator - Definition | Aldrete score chart

Does it matter if a patient wakes up promptly after general anesthesia? It does. An awake, alert patient will have minimal airway or breathing problems. When it’s time to walk away from your patient in the recovery room, you’ll worry less if your patient is already talking to you and has minimal residual effects of general anesthesia. Whether the surgery was a radical neck dissection, a carotid endarterectomy, a laparotomy, or a facelift, it’s preferable to have your patient as awake as possible in the recovery room.

What can you do to assure your patients wake up promptly? A Pubmed search will give you little guidance. There’s a paucity of data or evidence in the medical literature on how to wake patients faster. You’ll find data on ultra-short acting drugs such as propofol and remifentanil. This data helps, but the skill of waking up a patient on demand is more an art than a science. Textbooks give you little advice. Anesthesiologist’s Manual of Surgical Procedures, (4th Edition, 2009), edited by Jaffe and Samuels, has an Appendix that lists Standard Adult Anesthetic Protocols, but there is little specific information on how to titrate the drugs to ensure a timely wakeup.

Based on 29 years of administering over 20,000 anesthetics, this is my advice on how to wake patients promptly from general anesthesia:

  1. Propofol. Use propofol for induction of anesthesia. You may or may not choose to infuse propofol during maintenance anesthesia (e.g. at a rate of 50 mcg/kg/min) but if you do, I recommend turning off the infusion at least 10 minutes before planned wakeup. This allows adequate time for the drug to redistribute and for serum propofol levels to decrease enough to avoid residual sleepiness.
  2. Sevoflurane. Sevoflurane is relatively insoluble and its effects wear off quickly when the drug is ventilated out of the lungs at the conclusion of surgery. I recommend a maintenance concentration of 1.5% inspired sevoflurane in most patients. I drop this concentration to 1% while the surgeon is applying the dressings. When the dressings are finished, I turn off the sevoflurane and continue ventilation to pump the sevoflurane out of the patient’s lungs and bloodstream. The expired concentration will usually drop to 0.2% within 5-10 minutes, a level at which most patients will open their eyes.
  3. Nitrous oxide. Unless there is a contraindication (e.g. laparoscopy or thoractomy) I recommend you use 50% nitrous oxide. It’s relatively insoluble, and adding nitrous oxide will permit you to utilize less sevoflurane. I recommend turning off nitrous oxide when the surgeon is applying the dressings at the end of the case, and turning the oxygen flow rate up to 10 liters/minute while maintaining ventilation to wash out the remaining nitrous oxide.
  4. Narcotics. Use narcotics sparingly and wisely. I see overzealous use of narcotics as a problem. Prior to inserting an endotracheal tube, it’s reasonable to administer 50 – 100 mcg of fentanyl to a healthy adult or 0 -50 mcg of fentanyl to a geriatric patient. A small dose serves to blunt the hemodynamic responses of tachycardia or hypertension associated with larynogoscopy and intubation. Bolusing 250 mcg of fentanyl prior to intubation is an unnecessary overdose. The use of ongoing doses of narcotics during an anesthetic depends on the amount of surgical stimulation and the anticipated amount of post-operative pain. You may administer intermittent increments of narcotic (I may give a 50-100 mcg dose of fentanyl every hour) but I recommend your final narcotic bolus be given no less than 30 minutes prior to the anticipated wakeup. Undesired high levels of narcotic at the conclusion of surgery contribute to oversedation and slow awakening. If your patient complains of pain at wakeup, further narcotic is titrated intravenously to control the pain. Your patient’s verbal responses are your best monitor regarding how much narcotic is needed. Your goal at wakeup should be to have adequate narcotic levels and effect, but no more narcotic than needed.
  5. Intra-tracheal lidocaine. I recommend spraying 4 ml of 4% lidocaine into the larynx and trachea at laryngoscopy prior to inserting the endotracheal tube. I can’t cite you any data, but it’s my impression that patients demonstrate less bucking on endotracheal tubes at awakening when lidocaine was sprayed into their tracheas. Less bucking enables you to decrease anesthetic levels further while the endotracheal tube is still in situ.
  6. Local anesthetics. Local anesthetics are your friends at the conclusion of surgery. If the surgeon is able to blunt post-operative pain with local anesthesia or if you are able to blunt post-operative pain with a neuroaxial block or a regional block, your patient will require zero or minimal intravenous narcotics, and your patient will wake up more quickly.
  7. Muscle relaxants. Use muscle relaxants sparingly. Nothing will slow a wakeup more than a patient in whom you cannot reverse the paralysis with a standard dose of neostigmine. This necessitates a delay in extubation until muscle strength returns. Muscle relaxation is necessary when you choose to insert an endotracheal tube at the beginning of an anesthetic, but many cases do not require paralysis for the duration of the surgery. When you must administer muscle relaxation throughout surgery, use a nerve stimulator and be careful not to abolish all twitch responses. Avoid long-acting paralyzing drugs such as pancuronium, as you will have difficulty reversing the paralysis if surgery concludes soon after you’ve administered a dose. Use rocuronium instead. Avoid administering a dose of rocuronium if you believe the surgery will conclude within the next 30 minutes—it may be difficult to reverse the paralysis, and this will delay wakeup.
  8. Laryngeal Mask Airway (LMA). When possible, substitute an LMA for an endotracheal tube. Wakeups will be smoother, muscle relaxants are unnecessary, and narcotic doses can be titrated with the aim of keeping the patient’s spontaneous respiratory rate between 15- 20 breaths per minute.
  9. Temperature monitoring and forced air warming. Cold is an anesthetic. Strive to keep your patient normothermic by using forced air warming. If your patient’s core temperature is low, wakeup will be delayed.

10. Consider remaining in the operating room after surgery until your patient is awake enough to respond to verbal commands. This is my practice, and I recommend it for safety reasons. In the operating room you have all your airway equipment, drugs, and suction at your fingertips. If an unexpected emergence event occurs, you’re prepared. If an unexpected emergence event occurs in an obtunded patient in the recovery room, your resuscitation equipment will not be as readily available. If your patient is responsive to verbal commands in the operating room, your patient will be wakeful on arrival in the recovery room.

Is this protocol a recipe? Yes, it is. You’ll have your own recipe, and your ingredients may vary from mine. You may choose to administer desflurane instead of sevoflurane. You may choose sufentanil, morphine, or meperidine instead of fentanyl. My advice still applies. Use as little narcotic as is necessary, and try not to administer intravenous narcotic during the last 30 minutes of surgery. If you use a remifentanil infusion, taper the infusion off early enough so the patient is wakeful at the conclusion of surgery.

The principles I’ve recommended here are time-tested and practical. Follow these guidelines and you’ll experience two heartwarming scenarios from time to time:  1) Patients in the recovery room will ask you, “You mean the surgery is done already? I can’t believe it,” and 2) Recovery room nurses will ask you, “Did this patient really have a general anesthetic?  She’s so awake!”

Your chest will swell with pride, and you’ll feel like an artist. Good luck.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

HOW IS YOUR ANESTHESIA BILL CALCULATED?

THE ANESTHESIA CONSULTANT

How is your anesthesia bill calculated?

 

anesthesia billing

 

It depends. An anesthesiologist’s bill depends on several factors, including:

  1. The duration of the anesthesia care
  2. The complexity of the surgical procedure
  3. The insurance status of the patient

Let’s look at each of these factors in turn:

1. The duration of the anesthesia care.  Anesthesia provider bills are calculated by a simple formula:

Amount of Bill = (Number of Base Units + Number of Time Units) X the dollar value of a Unit.

Every anesthesia company assigns a monetary value to an anesthesia “Unit.” A “Unit” is a 15-minute length of time of anesthesia service. (The price of an anesthesia Unit varies. More on this topic later).

The total amount of an anesthesia bill depends largely on the duration of the anesthesia service, which depends on the duration of the surgery.

Anesthesia time begins when the anesthesia provider starts attending to the patient in the pre-operative area, and ends when the anesthesia provider transfers care to the post-anesthesia care unit (PACU) nurse or to the intensive care unit (ICU) nurse following the surgery.

For most surgeries, a typical timeline involves:

10-15 minutes of anesthesia exam in the pre-operative area,

5 minutes of time transporting the patient to the operating room,

5-10 minutes time inducing anesthesia,

10–40 minutes of time positioning, prepping, and draping the patient,

the entire surgical duration,

5-15 minutes of time to wake the patient up,

5-10 minutes of time to transport the patient to the PACU or ICU,

and 5-10 minutes time to sign the patient over to the nurse’s care in the PACU or ICU.

In the PACU, the anesthesiologist is responsible for the patient’s vital signs, pain control, nausea therapy, and the timing of the patient’s discharge from the PACU, even though the anesthesia billing time concluded when he or she signed the patient’s care to the PACU nurse. Typically the anesthesia provider returns to the pre-operative area to meet the next patient at this time, and the billing time for the next patient commences when the anesthesia provider begins attending to the next patient.

2. The complexity of the scheduled surgical procedure. The Base Unit value for any anesthetic varies with the complexity of the scheduled surgery. The Base Unit value can be as low as 3 Units for a simple procedure such as a finger or a toe surgery, or as high as 25 Units for open-heart surgery.  The Base Unit values are cataloged in a publication called the ASA (American Society of Anesthesiologists) Relative Value Guide. The Base Unit value reflects the degree of work and risk involved in the anesthetic management for each type of surgery.

3. The insurance status of the patient. The United States government sets a cap on how much Medicare and Medicaid patients can be billed. The dollar value per anesthesia Unit is severely discounted for Medicare and Medicaid patients to a number as low as one-fourth to one-fifth the amount a non-Medicare or Medicaid patient is billed.

                                                                                                                                               

FURTHER DISCUSSION…

THE PRICE OF AN ANESTHESIA UNIT: The price of an anesthesia Unit is set by the billing anesthesiologist and his or her anesthesia company. The price tends to be higher in major metropolitan centers, lower in rural areas, and lowest for Medicare patients. The price of an anesthesia Unit may vary from as high as $140/Unit in a major metropolitan area to a low of $20/Unit for a Medicare or a Medicaid patient.

EXAMPLE: Let’s look at a sample bill for an elbow surgery. The Base Unit value for elbow surgery is 3 Units. The surgery time was 1 hour, but the total anesthesia time from pre-operative area to the PACU sign out was 1 hour and 45 minutes. One hour and 45 minutes equals 7 Time Units. Let’s assume a Unit value price of $90/Unit.

Using the formula above,

Amount of Bill = (Number of Base Units + Number of Time Units)  X  the dollar value of a Unit.

OR

Amount of Bill = (3 Units + 7 Units) X $90/Unit = 10 X 90 = $900.

Will the anesthesia provider collect $900? Most likely not. Insurance companies negotiate with physicians, and the result of such negotiations may result in significant discounts paid on Unit values compared to billed rates. If the anesthesia group has a signed contract with an insurance company, the agreed reimbursement may be $60/Unit, and the maximal allowed bill would be $600.

In addition, if your insurance coverage requires you to pay for 20% of the bill, the insurance company may only pay 80%, or $480, and you will be expected to pay $120. If the anesthesiology company does not have a contract with the insurance provider, the insurance company will reimburse an out-of-network amount, usually less than the full $900, and you may be responsible for the balance of the bill (unless the anesthesia company is willing to discount the bill under these circumstances).

There are advantages of growing old. If you’re a Medicare patient, your anesthesia bill may total only $200:

(3 Units + 7 Units) X $20/Unit = 10 X 20 = $200.

COSMETIC SURGERY: Insurance companies do not pay for plastic surgeries such as liposuction, breast implants, or facelifts. Patients must pay the surgeon, operating room, and anesthesia bills in advance. Most anesthesiologists discount their customary rates in return for cash prepayment.

THE FUTURE: The nature of anesthesia billing may change in the future to embrace a concept known as “bundled payments.” Obamacare, or the Affordable Care Act, outlines provisions for bundled payments to hospitals rather than the traditional fee-for-service reimbursements described above. In a bundled payment model, the medical team will receive a lump sum from the government (or from an insurance company) for a surgical procedure. The medical center and physicians will negotiate and decide how to divide up the money between the surgeon, the anesthesiologist, and to the hospital (the hospital share will cover nurse salaries, technician salaries, supplies, and the overhead to run the hospital).

To date there is little data to support the advantage of bundled payments. The government hopes to save money by limiting what it pays out per procedure. Time will tell how prevalent this reimbursement model will be in the future of American healthcare economics.

When you buy retail goods, prices are available prior to purchase. With medical bills, you rarely know what the price of your medical care will be until you receive the bill weeks afterward. This is likely to change. There is momentum moving toward transparent pricing of medical fees, including listing of physician fees and facility fees prior to patient care. In the future you may have access to physician, hospital, and surgery center pricing to assist you in making your medical care choices.

SUMMARY: Your anesthesia bill will depend on how complex a surgery you are scheduled for, how long it takes to complete the procedure, and what kind of insurance coverage you have. Armed with this information, you may choose to contact your surgeon, the anesthesia company he or she works with, and your insurance company prior to your surgery to understand what your anesthesia bill is likely to be.

ANESTHESIA FACTS FOR NON-MEDICAL PEOPLE: ANESTHETIC TECHNIQUES

THE ANESTHESIA CONSULTANT

This column is for non-medical laypeople, and pertains to the different types of anesthetic techniques used in the 21st century. See below:

GENERAL ANESTHESIA

A general anesthetic renders the patient asleep and insensitive to pain for surgery. Prior to beginning anesthesia, the anesthesiologist places monitors of blood pressure, electrocardiogram, pulse and oxygen saturation of the blood. Before the anesthetic, oxygen is administered by mask to fill the patient’s lungs with 100% oxygen. Most adult patients are given general anesthesia by intravenous injection, usually of the medication propofol. This injection causes the patient to lose consciousness within 10 – 20 seconds. This is called the induction of anesthesia. The maintenance of anesthesia during surgery is done by mixing an anesthesia gas or gases with the oxygen. Typical inhaled anesthesia gases are nitrous oxide, sevoflurane, or isoflurane. Sometimes a continuous infusion of intravenous anesthetic such as propofol is given as well. The choice and dose of drugs is done by the anesthesia attending, based on the patient’s size, age, the type of surgery, and the anesthesiologist’s experience.

Many patients are given prophylactic anti-nausea medication during the anesthetic. If postoperative pain is anticipated, the anesthesiologist can also administer intravenous narcotics such a morphine, meperidine (Demerol), or fentanyl.

Depending on the patient’s medical condition and type of surgery, the anesthesiologist may protect the patient’s airway during the general anesthetic by placing a breathing tube through the mouth, either an endotracheal tube (ET Tube) into the patient’s windpipe, or a laryngeal mask airway (LMA) just above the voice box.

At the conclusion of surgery, the general anesthetic gases and/or intravenous anesthetic infusion(s) are discontinued. The patient usually regains consciousness within 5 – 15 minutes. The patient is then transferred to the recovery room.

SPINAL ANESTHESIA

Spinal anesthesia is done by the injection of local anesthetic solution into the low back into the subarachnoid space. Prior to beginning anesthesia, the anesthesiologist places monitors of blood pressure, electrocardiogram, pulse and oxygen saturation of the blood. The word subarachnoid translates to “below the arachnoid”. The arachnoid is one of the layers of the meninges covering the nerves of the spinal column. In the subarachnoid space lies the cerebral spinal fluid (CSF) which surrounds the spinal cord and brain. In a spinal anesthetic, the subarachnoid space is located with a needle by the anesthesiologist, and the appropriate anesthetic medications are injected.

Local anesthetics, such as lidocaine or bupivicaine (brand name Marcaine), given into the subarachnoid space, bring on sensory and motor numbness. The anesthesiologist chooses the dose and type of drug depending on the patient’s age, size, height, medical condition, and the type of surgery.

Following the onset of numbness from spinal anesthesia, the patient may either stay awake for surgery, or more often intravenous anesthesia is given to achieve a light sleep. Sometimes light general anesthesia is given to supplement spinal anesthesia.

EPIDURAL ANESTHESIA

Epidural anesthesia is done by the injection of local anesthetic solution, with or without a narcotic medication, into the low back into the epidural space. Prior to beginning anesthesia, the anesthesiologist places monitors of blood pressure, electrocardiogram, pulse and oxygen saturation of the blood. The word epidural translates to “outside the dura”. The dura is the outermost lining of the meninges covering the nerves of the spinal column. The epidural space is located with a needle by the anesthesiologist, and the appropriate anesthetic medications are injected.   Often, a tiny catheter is left in the epidural space, taped to the patient’s low back, to allow repeated doses of the medication to be given.  The catheter is removed at the end of surgery, or sometimes days later if continued epidural medications are administered for postoperative pain control.

Local anesthetics, such as lidocaine or bupivicaine (brand name Marcaine), given into the epidural space, bring on sensory and motor numbness. The anesthesiologist chooses the dose and type of drug depending on the patient’s age, size, height, medical condition, and the type of surgery.

Following the onset of numbness from epidural anesthesia, the patient may either stay awake for surgery, or more often intravenous sedation is given to achieve a light sleep. Sometimes light general anesthesia is given to supplement epidural anesthesia.

REGIONAL ANESTHESIA

Regional anesthesia is the injection of local anesthetic (either lidocaine or Marcaine) near a nerve to block that nerve’s function.  Examples of regional anesthesia include arm blocks (axillary block, interscalene block, subclavicular block), and leg blocks (femoral block, sciatic block, popliteal block, ankle block).  An advantage of regional anesthesia blocks is that the patient may remain awake for the surgery.  If desired, the anesthesia provider may administer intravenous sedation or general anesthesia in addition to the regional anesthetic, to allow the patient to sleep during the surgery–the advantage of this combined anesthetic technique is the regional anesthetic blocks all surgical pain and less sleep drugs are required.

INTRAVENOUS SEDATION ANESTHESIA

Some minor surgical procedures (for example: breast biopsies, eyelid surgery, some hernia surgeries) can be done with the combination of local anesthesia plus intravenous anesthesia sedation. Prior to beginning anesthesia, the anesthesiologist places monitors of blood pressure, electrocardiogram, pulse and oxygen saturation of the blood. The anesthesiologist is present for the entire surgery, and administers intravenous sedatives as required for the patient’s comfort and the surgeon’s needs.  If the sedation is deep enough, the intravenous sedation will be termed general anesthesia. While the patient is sedated, the surgeon usually injects local anesthetics into the surgical site to block both surgical and post operative pain.

Vigilance by an anesthesiologist during intravenous sedation is also known as Monitored Anesthesia Care, or MAC.

PEDIATRIC ANESTHESIA

Because the separation of a young child from his or her parents can be one of the most distressing aspects of the perioperative experience, many children benefit significantly from oral preoperative sedation with midazolam. This relatively pleasant-tasting liquid is given by mouth about twenty minutes prior to the start of the anesthetic. Although the midazolam rarely causes children to fall asleep, it does reduce anxiety dramatically, allowing for a much smoother separation from parents. It also tends to cause a wonderful short term amnesia, so that the children often have no recollection of separating from their parents, or even of going to the operating room.
Although the initial anesthetic is usually administered via an intravenous infusion in adult patients, this approach requires starting an IV while the patient is still awake. This technique would be quite unpopular with younger children.  Most young children prefer to go to sleep breathing a gas, a technique known as an inhalation induction. This technique is used for almost all routine surgeries, but cannot safely be employed in certain rare situations, such as emergencies.

An inhalation induction consists of the child breathing a relatively pleasant smelling anesthetic vapor – usually sevoflurane – via a facemask for approximately 30 to 60 seconds. The child loses consciousness while breathing the gas, and the IV can then be started painlessly. Generally, the child continues to breath the gas throughout the duration of the surgery, either via the facemask or an endotracheal tube, depending on the duration and type of surgery. It is this breathing of the gas which keeps the child anesthetized. At the end of the surgery, the gas is discontinued, and the child begins to awaken.

Prior to awakening, children may be given either analgesics (pain medicines) or anti-emetics (drugs which reduce the likelihood of nausea and vomiting). The type of surgery will determine which of the many possible medications will be used for these purposes. The purpose of these medications is to make the child’s awakening as calm and pleasant as possible. Equally important in this regard is reuniting the child with his or her parents as quickly as possible.
Despite best attempts, it is important for parents to realize that children, especially those less than five years of age, often are somewhat cranky and irritable following anesthesia and surgery. We do our best to minimize this, but we cannot prevent it in all cases. Similarly, some children will experience postoperative nausea and vomiting despite receiving medications which are intended to prevent it.

THE ANESTHESIA CONSULTANT

This column is specifically for my non-medical layperson readers, and is a discussion of the different types of anesthesia for specialty surgeries. See below:

 

I.  CHILDBIRTH (OBSTETRIC ANESTHESIA):

Most obstetric anesthesia is for either vaginal delivery or for Cesarean sections.

Anesthesia for Vaginal Delivery:  Anesthesia for vaginal delivery is utilized to diminish the pain of labor contractions, while leaving the mother as alert as possible, with as muscle strength as possible, to be able to push the baby out at the time of delivery.  Anesthesia for labor and vaginal delivery is usually accomplished by epidural injection of the local anesthetics bupivicaine (brand name Marcaine) or ropivicaine.

is done by the injection of local anesthetic solution, with or without a narcotic medication, into the low back into the epidural space. Prior to beginning anesthesia, the anesthesiologist places monitors of blood pressure, electrocardiogram, pulse and oxygen saturation of the blood.

The word epidural translates to “outside the dura”. The dura is the outermost lining of the meninges covering the nerves of the spinal column. The epidural space is located with a needle by the anesthesiologist, and the appropriate anesthetic medications are injected.   Often, a tiny catheter is left in the epidural space, taped to the patient’s low back, to allow repeated doses of the medication to be given.  The catheter is removed after childbirth.

Anesthesia for Cesarean Section: Cesarean section is a surgical procedure in which the obstetrician makes an incision through the skin of the lower abdomen, and through the wall of the uterus, or womb, to extract the baby without the child requiring a vaginal delivery.  Anesthesia for Cesarean section is usually a spinal or an epidural anesthetic, which leaves the mother as alert as possible, while rendering surgical anesthesia to her abdomen and pelvis.  Spinal or epidural anesthesia is accomplished by injection of local anesthetics, with or without a narcotic medication, into the low back into the subarachnoid or the epidural space. The anesthesiologist remains present for the entire surgical procedure, to assure that the mother is comfortable and that all vital signs are maintained as close to normal limits as possible.

In a minority of cases, the anesthesia provider will administer a general anesthetic for Cesarean section surgery.  The most common indications for general anesthesia are (1) emergency Cesarean, when there is no time for a spinal or epidural block;  and (2) significant bleeding by the mother, leading to a low blood volume, which is an unsafe circumstance to administer a spinal or epidural block.  General anesthetics for Cesarean section carry an increased risk over spinal/epidural anesthesia, primarily because the mother is no longer able to breath on her own and maintain her own airway.

open heart surgery

II.  CARDIAC SURGERY/OPEN HEART SURGERY:

Open heart surgery requires specialized equipment.  Anesthesia for cardiac surgery is complex, and the following is a brief summary:  Prior to the surgery, the anesthesiologist inserts a catheter into the radial artery at the wrist, to monitor the patient’s blood pressure continuously, rather than relying on a blood pressure cuff.  This enables the anesthesiologist to fine-tune the blood pressure, never allowing it to be too high or too low for an extended period of time.  The anesthesiologist also inserts a catheter (a central venous catheter, or CVP catheter) into a large vein in the patient’s neck.  The anesthesiologist uses this catheter to monitor the pressure inside the heart, and also to administer infusions of potent medications into the central circulation to raise or lower the blood pressure, or to increase the heart’s pumping function.

After the patient is anesthetized, the anesthesiologist often inserts a Transesophageal Echocardiogram (TEE) probe into the patient’s mouth, down the esophagus, and into the stomach.  The TEE gives the anesthesiologist a two-dimensional image of the beating heart and the heart valves in real time, and enables him or her to adjust medications and fluid administration as needed to keep the patient stable.

For open heart surgery, once the chest is open, the cardiac surgeon inserts additional tubes into the veins and arteries around the heart, diverting the patient’s blood from the heart and lungs into a heart-lung machine located alongside the operating table.  During the time the patient is connected to the heart-lung machine, the patient’s heart can be stopped so that the surgeon can operate on a motionless heart.

When the surgeon has completed the cardiac repair, the heart is restarted, and the heart-lung machine is disconnected from the patient.

As the heart resumes beating, the anesthesiologist manages the drug therapy and intravenous fluid therapy to optimize the cardiac function.

III.  ANESTHESIA FOR NEUROSURGERY (BRAIN SURGERY):

Intracranial (brain) surgery requires exacting maintenance of blood pressure, heart rate, and respiratory control.  Prior to the surgery, the anesthesiologist inserts a catheter into the radial artery at the wrist, to monitor the patient’s blood pressure continuously, rather than relying on a blood pressure cuff.  This enables the anesthesiologist to fine-tune the blood pressure, never allowing it to be too high or too low for an extended period of time.  The anesthesiologist also inserts a catheter (a central venous catheter, or CVP catheter) into a large vein in the patient’s neck.  The anesthesiologist uses this catheter to monitor the pressure inside the heart, and also to administer infusions of potent medications into the central circulation to raise or lower the blood pressure.

The anesthetic technique is designed to provide a motionless operating field for the surgeon.  After the anesthesiologist anesthetizes the patient, he or she inserts the endotracheal tube into the windpipe.  The patient is often hyperventilated, because hyperventilation causes the blood vessels in the brain to constrict, and makes the volume of the the brain decrease.  The relaxed brain affords the surgeon more room to dissect and expose brain tumors or aneurysms.

An important goal of the anesthetic is a quick wake-up at the conclusion of surgery, so that (1) normal neurological recovery of the patient can be confirmed, and (2) the patient is alert enough to  maintain their own airway and breathe on their own.  Most brain surgery patients spend at least one night in the intensive care unit (ICU) after surgery.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

HOW DOES THE ANESTHESIOLOGIST DECIDE WHAT DOSE OF ANESTHETIC TO GIVE A PATIENT?

THE ANESTHESIA CONSULTANT

This column is directed to my non-medical layperson readers. How does an anesthesiologist decide what dose of anesthetic to administer to a patient? You are a 100-pound, 70-year-old woman. Your son is a 200-pound, 35-year-old man. Do you both require the same doses of general anesthetic if you each need to have your gall bladder removed?

No, you do not.

Anesthesiologists use several criteria to choose the correct dose for your anesthetic.

  • Your weight.      All intravenous anesthetic drugs, such as hypnotics (propofol, sodium pentothal), narcotics (morphine, Demerol, fentanyl), anxiolytics (Versed, Ativan), or muscle paralyzing drugs (rocuronium, vecuronium, succinylcholine) are dosed on a milligram-per-kilogram basis. If you weigh half as much as your neighbor, if all other factors are equal, then you will receive approximately half as many milligrams of the injectable medication as she will.
  • Your age.        Abundant research has demonstrated the relationship between age and anesthetic effect. Youthful patients require more milligrams-per-kilogram of body weight. A teenager may require twice the dose of an 80-year-old patient.
  • How stimulating the surgery is, and how much pain there will be postoperatively.          A non-painful surgery, such as the repair of a small tendon in a finger, will not require large doses of narcotics or pain relievers post-operatively. A painful surgery, such as on open abdominal procedure to remove a pancreatic or liver tumor, will require more narcotics and increased doses of anesthetics. If postoperative pain is blocked by local anesthetic injection in the surgical site or by a nerve block, a patient will require less general anesthetic medications.
  • The duration of the surgery.      An 8-hour surgery will require a longer exposure to more anesthetic drugs than a 1-hour surgery.
  • Your preoperative exposure to central nervous system depressants.      All else being equal, a patient who drinks 12 beers every day will require more anesthesia than a teetotaler who never drinks. A patient who is addicted to chronic prescription painkillers will require more anesthesia than a non-addict.

Inhaled anesthetics, such as sevoflurane, desflurane, isoflurane, or nitrous oxide, are administered in standard concentrations, independent of all the above factors except the patient’s age.  Inhaled anesthetics are mixed into vapor by an anesthesia machine which is connected to the your breathing system during the surgery. The anesthesia machine will usually be set to deliver either sevoflurane 1-2 %, desflurane 3 – 6 %, or isoflurane 0.8 – 1.5 %. The required concentration of these potent inhaled anesthetic decreases with age. The dose for teenager is approximately twice the dose required for a 90-year-old patient.

LETHAL INJECTION AND THE ANESTHESIOLOGIST

THE ANESTHESIA CONSULTANT

Lethal injection requires someone to administer anesthetic medications in high concentrations, without supporting breathing or cardiac function. This column discusses lethal injection and the anesthesiologist. In the 2011 movie The Lincoln Lawyer, Matthew McConaughey’s character, a criminal defense lawyer working in Los Angeles, taunts his client who is on trial for murder to tell the truth in order to “avoid the needle.”  The needle he is talking about is the specter of execution by lethal injection.

lethal injection and the anesthesiologist

Since 2006, there have been no death penalty executions by lethal injection in the state of California.  In February 2006, U.S. District Court Judge Jeremy D. Fogel blocked the execution of convicted murderer Michael Morales because of concerns that if the three-drug lethal injection combination was administered incorrectly, it could lead to suffering for the condemned, and potential cruel and unusual punishment.  The ruling arose from an injunction made by the U.S. 9th Circuit Court of Appeals, which stated that an execution could only be carried out by a medical technician legally authorized to administer intravenous medications.  This led to a moratorium of capital punishment in California, as the state was unable to obtain the services of a licensed medical professional to carry out an execution.

The three intravenous drugs involved in lethal injection are (1) sodium thiopental, a barbiturate drug that induces sleep, (2) pancuronium, a drug that paralyzes all muscles, making movement and breathing impossible, and (3) potassium chloride, a drug that induces ventricular fibrillation of the heart, causing cardiac arrest.  The potential of cruel and unusual punishment can occur if the sodium thiopental does not reliably induce sleep, so that the individual to be executed is awake and aware when the paralyzing drug freezes all muscular activity.

How could sodium thiopental fail to induce sleep?  The lethal injection administered dose of sodium thiopental is always a massive dose, up to 3000 mg.  To compare, the usual dose of sodium thiopental administered by an anesthesiologist to begin a general anesthetic is 200 mg.  The 15-fold increase in the dose should insure lack of awareness, right?

Not necessarily.  What if the intravenous catheter or needle is incorrectly positioned, so that the drug does not enter the vein in a reliable fashion?  Is this a possibility?  It is.  If the catheter is not inserted by a trained medical professional, it’s possible that the catheter will be outside of the vein, and the intended medications will spill into the soft tissues of the arm.  The intended site of action of sodium thiopental is the brain.  To reach the brain, the drug must be correctly delivered into a vein.

Cases in which failure to establish or maintain intravenous access have led to executions lasting up to 90 minutes before the execution was complete.Thus, the role of a medical professional to insert the intravenous catheter and administer the lethal injection is critical.  The dilemma is that medical professionals are trained to save lives, not to execute people.  The Hippocratic Oath clearly states that physicians must “do no harm” to their patients.

The American Medical Association states, “A physician, as a member of a profession dedicated to preserving life when there is hope of doing so, should not be a participant in a legally authorized execution.”

The American Society of Anesthesiologists states, “Although lethal injection mimics certain technical aspects of the practice of anesthesia, capital punishment in any form is not the practice of medicine … The American Society of Anesthesiologists continues to agree with the position of the American Medical Association on physician involvement in capital punishment. The American Society of Anesthesiologists strongly discourages participation by anesthesiologists in executions.”

The American Nurses Association states, “The American Nurses Association is strongly opposed to nurse participation in capital punishment. Participation in executions is viewed as contrary to the fundamental goals and ethical traditions of the profession.”

Without a trained medical professional to administer the intravenous catheter and inject the drugs in a reliable fashion, the practice of lethal injection has stalled in the State of California.  The last prisoner executed by lethal injection in California was Clarence Ray Allen on January 17, 2006.

In 2010, a Riverside County judge scheduled the execution of Albert Greenwood Brown, after a California court lifted an injunction against capital punishment with the certification of new procedures.  The new procedures included the option of increasing the sodium thiopental dose to 5000 mg, and administering the drug alone without the pancuronium and potassium chloride.  (In this scenario, death would occur because the large dose of sodium thiopental would by itself induce both general anesthesia and the cessation of breathing, leading to death by lack of sufficient oxygen levels to the brain and heart.)  However, prior to the execution, the same Judge Jeremy D. Fogel halted the execution to permit time to determine whether the new injection procedures addressed defense arguments of cruel and unusual punishment.

An additional barrier to lethal injection arose in January 2011, as Hospira Corporation, the sole manufacturer of sodium thiopental, announced that they would stop making the anesthetic sodium thiopental, the key component in the drug cocktails used by 35 states for chemical executions.

Hospira had planned to shift production of thiopental from the U.S. to Italy, but Italian officials wanted assurances that the drug would not be used for lethal injections.  Hospira’s response was that while they “never condoned” the use of thiopental in executions, the company determined that it could not prevent corrections departments in the United States from obtaining the drug. “Based on this understanding, we cannot take the risk that we will be held liable by the Italian authorities if the product is diverted for use in capital punishment,” Hospira said in a statement.

The American Society of Anesthesiologists released a statement on January 21, 2011 condemning Hospira’s decision to cease manufacturing sodium thiopental. The American Society of Anesthesiologists “certainly does not condone the use of sodium thiopental for capital punishment, but we also do not condone using the issue as the basis to place undue burdens on the distribution of this critical drug to the United States. It is an unfortunate irony that many more lives will be lost or put in jeopardy as a result of not having the drug available for its legitimate medical use.”  According to the American Society of Anesthesiologists, thiopental is an important alternative for geriatric, neurologic, cardiovascular and obstetric patients “for whom the side effects of other medications could lead to serious complications.”

In current anesthetic practice in the U.S. and around the world, sodium thiopental is occasionally but rarely utilized in anesthetic or intensive care unit practice.  Propofol replaced sodium thiopental, as propofol is a shorter-acting drug with fewer side effects of post-operative sleepiness and nausea.

Propofol or other sedative drugs such as midazolam, Valium, etomidate, or methohexital could be used to replace sodium thiopental to carry out lethal injection, but the key issue of obtaining a trained medical professional to administer the drug still looms as a roadblock.

I recommend The Lincoln Lawyer as riveting entertainment, but when Matthew McConaughey urges the defendant to “avoid the needle” of lethal injection, you have to understand … it’s unlikely any anesthesiologist is ever going to assist in that execution.

IS YOUR GRANDMOTHER TOO OLD FOR SURGERY?

emailrjnov@yahoo.com
THE ANESTHESIA CONSULTANT

This column is for my non-medical layperson readers. Your 85-year-old grandmother had two gallstone attacks in the past 6 months. Is she too old for surgery? Is it safe for her to have her gallbladder removed?

 

It depends. A general surgeon would serve as the consultant as to the natural history of the gallbladder disease. He may opine that future gallstone attacks are likely, and that the severe pain and fever of acute cholelithiasis is possible.

If your grandmother was 50 years old, you’d expect the surgical team to operate on her. For an 85-year-old patient, the surgical prognosis depends on her medical condition. She needs preoperative assessment from a specialist, and that specialist would be an anesthesiologist.

At Stanford University the anesthesia department is known as the Department of Anesthesia, Perioperative and Pain Medicine. The word perioperative refers to medical practice before, during, and after surgical operations. Preoperative assessment refers to the medical work-up before a surgical procedure—the work-up which establishes that all necessary diagnostic and therapeutic measures have been taken prior to proceeding to the operating room.

Age alone should not be a deterrent to surgery. Increased life expectancy, safer anesthesia, and less invasive surgical techniques such as laparoscopy have made it possible for a greater number of geriatric patients to undergo surgical intervention. The decision to operate should not be based on age alone, but should be based on an assessment of the risk-to-benefit ratio of each individual case. Surgical risk and outcome in patients 65 years old and older depend primarily on four factors: (1) age, (2) whether the surgery is elective or urgent, (3) the type of procedure, and (4) the patient’s physiologic status and coexisting disease. (reference: Miller’s Anesthesia, Chapter 71, Geriatric Anesthesia, 7th Edition, 2009).

Let’s look at each of these four factors:

1)   Age. Data support that increasing age increases risk.  Complication rates and mortality rates are higher for patients in their 80’s than for patients in their 60’s.

2)   Emergency surgery. Patients presenting for emergency surgery are often sicker than patients for elective surgery, and have increased risk.  There may be insufficient time for a full preoperative medical workup or tune-up prior to anesthesia.

3)   Type of procedure. A trivial procedure such as finger or toe surgery carries significantly less risk than open heart surgery or intra-abdominal surgery.

4)   Coexisting disease. The American Society of Anesthesiologists has a classification system for patients which categorizes how healthy or sick a patient is (see the American Society of Anesthesiologists Physical Status Class categories below). A patient with severe heart or lung disease is at higher risk than a rigorous patient who hikes, bikes or swims daily without heart or lung pathology.

Let’s examine these four factors in your 85-year-old grandmother. Regarding factor (1), she is old, and therefore she carries increased risk solely because of her advanced age. Regarding factor (2), her surgery is non-emergent, and this is in her favor. Regarding factor (3), her procedure requires intra-abdominal surgery, which is more invasive and carries more cardiac and respiratory risk than a trivial hand or foot or cataract surgery. She’ll have to cope with post-operative abdominal pain and pain on deep breathing, each of which can affect her lung function after anesthesia. Factor (4), her pre-existing medical history and physical condition, is the key element in her pre-operative consult.

The American Society of Anesthesiologists Physical Status Class categorizes patients as follows:

Class I   – A normal healthy patient. Almost no one over the age of 65 is an ASA I.

Class II  – A patient with mild systemic disease.

Class II  – A patient with severe systemic disease.

Class IV – A patient with severe systemic disease that is a constant threat to life.

Let’s say your grandmother has well-treated hypertension, asthma, hyperlipidemia, and obesity. She is reasonably active without limiting heart or lung disease symptoms, and she can climb two flights of stairs without shortness of breath.

She is an ASA Class II.

What if your grandmother had a past heart attack which left her short of breath walking up two flights of stairs, or she has kidney failure and is on dialysis, or she has severe emphysema that leaves her short of breath walking up two flights of stairs? These problems make her an ASA Class III, and she is at higher risk than a Class II patient.

If your 85-year-old grandmother is short of breath at rest or has angina at rest, due to either heart failure or chronic lung disease, she is an ASA Class IV patient, and she is at very high risk for surgery and anesthesia.

Laypersons can access an online surgical risk calculator, sponsored by the American College of Surgeons, at www.riskcalculator.facs.org, and enter the specific data for any surgical patient, to estimate surgical risk.

If your grandmother has well-treated hypertension, asthma, hyperlipidemia, and obesity as described above, then her operative risk is moderate and most anesthesiologists will be comfortable giving her a general anesthetic. The American College of Surgeons risk calculator estimates her risk of death, pneumonia, cardiac complications, surgical site infection, or blood clots as < 1%. Her risk of serious complication is estimated at 2%.

How will the anesthesiologist proceed?

For an 85-year-old patient, most anesthesiologists will require a written consultation note from an internal medicine primary care doctor or a cardiologist prior to proceeding with anesthesia. The anesthesiologist will then confirm that all necessary diagnostic and therapeutic measures have been done prior to surgery. Routine lab testing is not be ordered because of age alone, but rather pertinent lab tests are done as indicated for the particular medical problems of each patient.

The anesthesiologist then explains the risks of anesthesia and obtains informed consent prior to the surgery. He or she will explain that an 85-year-old patient with treated hypertension, asthma, hyperlipidemia, and obesity has a higher chance of heart, lung, or brain complications than a young, healthy patient. Your grandmother will have to accept the risks as described by the anesthesiologist.

What do anesthesiologists do differently for geriatric anesthetics, in contrast to anesthesia practice on young patients?

(1) Anesthesiologists use smaller doses of drugs on elderly patients than they do on younger patients. Geriatric patients are more sensitive to anesthetic drugs, and the effect of the drugs will be more prolonged.

(2) Geriatric patients have progressive loss of functional reserve in their heart, lungs, kidney, and liver systems. The extent of these changes varies from patient to patient, and each patient’s response to surgery and anesthesia is monitored carefully. (Miller’s Anesthesia, Chapter 71, Geriatric Anesthesia, 7th Edition, 2009). The anesthesiologist’s routine monitors will include pulse oximetry, electrocardiogram, automated blood pressure readings, temperature monitoring, and monitoring of all inspired gases and anesthetic concentrations. Because most anesthetic drugs cause decreases in blood pressure, anesthesiologists slowly titrate additional anesthetic doses as needed, and remain vigilant for blood pressure drops that are excessive or unsafe.

What about mental decline following geriatric surgery?

Postoperative short-term decrease in intellect (decrease in cognitive test performance) during the first days after surgery is well documented, and typically involves decreases in attention, memory, and fine motor coordination. Early cognitive decline after surgery is largely reversible by 3 months. The reported incidence of cognitive dysfunction after major noncardiac surgery in patients older than 65 years is 26% at 1 week and 10% at 3 months. (reference: Johnson T, Monk T, Rasmussen LS, et al: Postoperative cognitive dysfunction in middle-aged patients. Anesthesiology 2002; 96:1351-1357).

In conclusion, the decision to proceed with your grandmother’s surgery and anesthesia requires an informed assessment of the benefit of the surgery versus the risks involved. Well-trained anesthesiologists anesthetize 85-year-old patients every day, with successful outcomes. My advice is to choose a medical center with fine physician anesthesia providers, and heed their consultation regarding whether your grandmother poses any unacceptable risk for surgery and anesthesia.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

LANDING THE ANESTHESIA PLANE: WHEN SHOULD YOU EXTUBATE THE TRACHEA?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

This column is for my readers who are anesthesia professionals. When should you extubate the trachea? Clinical Case for Discussion: You’re anesthetizing a 60-year-old woman for a thyroidectomy. The surgeon tells you, “If this woman bucks on the endotracheal tube on awakening it could cause a neck hematoma and damage my surgical closure. Can you extubate her deep?”

 

Discussion: The patient has a normal airway, and she is healthy and slender. You decide to comply with the surgeon’s request and remove the endotracheal tube (ET tube) at the end of surgery while the patient is still fully anesthetized. You turn off the nitrous oxide, allow the patient to breath 100% oxygen and 3% sevoflurane, and suction the patient’s throat. You deflate the cuff on the ET tube and remove the tube. Once the tube is withdrawn, you turn off all anesthetics. At this point the patient coughs and her mouth fills with yellow gastric contents. You suction the mouth again, but the patient develops upper airway obstruction. The oxygen saturation drops to 80%. Your diagnosis is laryngospasm. You attempt to apply continuous positive airway pressure with an anesthesia mask, but her oxygen saturation falls to 70%. Panicked, you inject 100 mg of IV succinylcholine to re-paralyze the patient, and you perform laryngoscopy and reintubate her. After the ET tube is replaced, the oxygen saturation returns to 100%. You suction through the lumen of the ET tube, and you find yellow gastric material inside the lungs. You diagnose aspiration.

After a 10½ hour flight from Seoul, Korea, an Asiana airplane crashed on landing at San Francisco Airport on July 6, 2013. Aviation and anesthesia have similarities. The takeoff and landing of an airplane, just as induction and emergence from anesthesia, are more complex events than piloting the middle of a plane flight or managing the maintenance phase of a long anesthetic.

The timing of the removal of the endotracheal tube at the end of an anesthetic requires skill and judgment. Does deep extubation ever make sense? During my first year after residency training, a gray-haired anesthesia attending at my new medical center told me, “Richard, in private practice you never extubate anyone deep.” Twenty-seven years later, I’m writing to convince you he was right.

Let’s define “deep extubation.” Per Miller’s Anesthesia, 7th Edition, 2009, Chapter 50, “Extubation may be performed at different depths of anesthesia, with the terms ‘awake,’ ‘light,’ and ‘deep’ often being used. ‘Light’ implies recovery of protective respiratory reflexes and ‘deep’ implies their absence. ‘Awake’ implies appropriate response to verbal stimuli. ‘Deep’ extubation is performed to avoid adverse reflexes caused by the presence of the tracheal tube and its removal, at the price of a higher risk of hypoventilation and upper airway obstruction. Straining, which could disrupt the surgical repair, is less likely with ‘deep’ extubation. Upper airway obstruction and hypoventilation are less likely during ‘light’ extubation, at the price of adverse hemodynamic and respiratory reflexes.”

The medical literature describes deep extubation as extubating a patient who is still breathing 1.5 times the minimal alveolar concentration (MAC) of inhaled anesthetic. A 2004 study examined 48 children tracheally extubated while deeply anesthetized with 1.5 times the MAC of desflurane (Group D) or sevoflurane (Group S). No serious complications occurred in either group, and the time to discharge was not significantly different between groups. The study concluded that deep extubation of children can be performed safely with desflurane or sevoflurane. (Valley RD, Anesth Analg. 2003 May;96(5):1320-4, Tracheal extubation of deeply anesthetized pediatric patients: a comparison of desflurane and sevoflurane.)

In a prospective trial, 100 children age<16 years, each with at least one risk factor for perioperative respiratory adverse events (e.g. current or recent upper respiratory tract infection or asthma) were randomized to extubation under deep anesthesia or extubation when fully awake after tonsillectomy. There were no differences in respiratory adverse events (laryngospasm, bronchospasm, persistent coughing, airway obstruction, or desaturation <95%). Tracheal extubation in fully awake children was associated with a greater incidence of persistent coughing (60 vs. 35%, P = 0.028), however the incidence of airway obstruction relieved by simple airway maneuvers in children extubated while deeply anaesthetized was greater (26 vs. 8%, P = 0.03).

Seventy healthy patients between 2 and 8 yr of age who had elective strabismus surgery or tonsillectomy were randomly assigned to group 1 (awake extubation) or group 2 (anesthetized extubation). The incidence of airway-related complications such as laryngospasm, croup, sore throat, excessive coughing, and arrhythmias was not different between the two groups. The authors concluded that the anesthesiologist’s preference or surgical requirements may dictate the choice of extubation technique in otherwise healthy children undergoing elective surgery. (Patel RI, Anesth Analg. 1991 Sep;73(3):266-70. Emergence airway complications in children: a comparison of tracheal extubation in awake and deeply anesthetized patients).

In an informal poll of the private practice anesthesiologists at Stanford University, the incidence of deep extubation (i.e. patient extubated asleep while breathing >1.5 MAC of inhaled anesthetic) approached zero. Why do I and my colleagues avoid deep extubation? If you have a life-saving and life-preserving device such as an endotracheal tube safely in place in your patient, and your goal is to maintain the values of Airway, Breathing, and Circulation, why remove that life-preserving device prematurely without any evidence that such a removal is beneficial? Why leave your anesthetized patient with an unprotected airway?

I cannot cite you outcome data that shows awake extubation provides superior outcomes to deep extubation, but with modern short-acting anesthetics such as propofol, sevoflurane, and desflurane, a well-trained anesthesiologist can decrease anesthetic depth quickly and have their patient very awake within minutes after the conclusion of surgery. Per Miller’s Aesthesia, “Rapid recovery of consciousness shortens the at-risk time during extubation and may reduce morbidity, particularly in obese patients. … Nitrous oxide, sevoflurane, and desflurane all contribute to rapid recovery, particularly after prolonged procedures.”

If your patient vomits on emergence and the ET tube is still in situ, the cuff on the ET tube will protect their lower airway. And if you choose to extubate your patient awake, the occurrence of laryngospasm will be, in this author’s experience, rare.

It’s true that coughing on an ET tube can disrupt surgical repairs, increase intracranial pressure, increase intraocular pressure, or cause hypertension and tachycardia, but per Miller’s Anesthesia, “Marked increases in arterial blood pressure and heart rate occur frequently at the time of ‘light’ extubation. These effects are alarming but normally transient, and there is little evidence of adverse consequences.”

My advice: Use light levels of general anesthetics on your intubated patients, and learn how to wake your patients from general anesthesia quickly at the conclusion of surgery. Don’t suction the patient until you are ready to remove the ET tube, because the suction catheter stimulates early coughing.

The ET tube is your friend. I’d recommend you don’t pull it out until you’re certain you don’t need it any more.

The definitive reference from the medical literature on this topic is Difficult Airway Society Guidelines for the management of tracheal extubation, written by Popat M.

WHY DOES ANYONE DECIDE THEY WANT TO BECOME AN ANESTHESIOLOGIST?

THE ANESTHESIA CONSULTANT

A question anesthesiologists are commonly asked is, “Why did you want to become an anesthesiologist?”

This image has an empty alt attribute; its file name is anesthesiologist.jpg

Let’s assume a young man or woman has the discipline and intellect to attend medical school. Once that individual gains their M.D. degree, they will choose a specialty from a long line-up that includes multiple surgical specialties (general surgery, orthopedics, urology, neurosurgery, cardiac surgery, ophthalmology, plastic surgery, ear-nose-and-throat surgery), internal medicine, pediatrics, family practice, dermatology, radiology, invasive radiology, radiation oncology, allergy-immunology, emergency medicine, and anesthesiology.

Why choose anesthesiology? I offer up a list of the reasons individuals like myself chose this specialty:

  1. Anesthesiologists do acute care rather than clinic care or chronic care. Some doctors enjoy sitting in a clinic 40+ hours a week, talking to and listening to patients. Other doctors prefer acute care, where more exciting things happen moment to moment. It’s true that surgeons do acute care in the operating room, but most surgeons spend an equal amount of time in clinic, seeing patients before and after scheduled surgical procedures. Chronic care in clinics can be emotionally taxing. Ordering diagnostic studies and prescribing a variety of pills suits certain M.D.’s, but acute care in operating rooms and intensive care units is more stimulating. It’s exciting controlling a patient’s airway, breathing, and circulation. It’s exciting having a patient’s life in your hands. Time flies.
  2. Patients like and respect their anesthesiologist, and that feels good. Maybe it’s because we are about to take each patient’s life into our hands, but during those minutes prior to surgery, patients treat anesthesiologists very well. I tend to learn more about my patients’ personal lives, hobbies, and social history in those 10 minutes of conversation prior to surgery than I ever did in my internal medicine clinic.
  3. An anesthesiologist’s patients are unconscious the majority of time. Some anesthesiologists are attracted to this aspect. An unconscious patient is not complaining. In contrast, try to imagine a 50-hour-a-week clinic practice as an internal medicine doctor, in which every one of your patients has a list of medical problems they are eager to tell you about.
  4. There is tremendous variety in anesthesia practice. We take care of patients ranging in ages from newborns to 100-year-olds. We anesthetize patients for heart surgery, brain surgery, abdominal or chest surgeries, bone and joint surgeries, cosmetic surgery, eye surgery, urological surgery, trauma surgery, and organ transplantation surgery. Every mother for Cesarean section has an anesthetist, as do mothers for many vaginal deliveries for childbirth. Anesthesiologists run intensive care units and anesthesiologists are medical directors of operating rooms as well as pain clinics.
  5. Anesthesiologists work with a lot of cool gadgets and advanced technology. The modern anesthesia workstation is full of computers and computerized devices we use to monitor patients. The modern anesthesia workstation has parallels to a commercial aircraft cockpit.
  6. Lifestyle. We work hard, but if an anesthesiologist chooses to take a month off, he or she can be easily replaced during the absence. It’s very hard for an office doctor to take extended time away from their patients. Many patients will find an alternate doctor during a one month absence if the original physician is unavailable. This aspect of anesthesia is particularly attractive to some female physicians who have dual roles as mother and physician, and choose to work less than full-time as an anesthesiologist so they can attend to their children and family.
  7. Anesthesia is a procedural specialty. We work with our hands inserting IV’s, breathing tubes, central venous IV catheters, arterial catheters, spinal blocks, epidural blocks, and peripheral nerve blocks as needed. It’s fun to do these procedures. Historically, procedural specialties have been higher paid than non-procedural specialties.

What about problematic issues with a career in anesthesia? There are a few:

  1. We work hard. Surgical schedules commonly begin at 7:30 a.m., and anesthesiologists have to arrive well before that time to prepare equipment, evaluate the first patient, and get that patient asleep before any surgery can commence. After years of this, my internal alarm clock tends to wake me at 6:00 a.m. even on weekends.
  2. Crazy hours. Every emergency surgery—every automobile accident, gunshot wound, heart transplant, or urgent Cesarean section at 3 a.m. needs an anesthetist. Working around the clock can wear you out.
  3. The stakes are high if you make a serious mistake. In a clinic setting, an M.D. may commit malpractice by failing to recognize that a patient’s vague chest pain is really a heart attack, or an M.D. may fail to order or to check on an important lab test, leading to a missed diagnosis. But in an operating room, the malpractice risks to an anesthesiologist are dire. A failure in properly insert a breathing tube can lead to brain death in minutes. This level of tension isn’t for everyone. Some doctors are not emotionally suited for anesthesia practice.
  4. In the future, anesthesia doctors may gradually lose market share of their practice to nurse anesthetists. You can peruse other columns in this blog where I’ve discussed this issue.
  5. Anesthesiologists don’t bring any patients to a medical center. In medical politics, this can be problematic. Anesthesiologists have limited power in some negotiations, because we can be seen as service providers rather than as a source of new patient referrals for a hospital. Some hospital administrators see an anesthetist as easily replaced by the next anesthetist who walks through the door, or who offers to work for a lower wage.

The positive aspects of anesthesiology far outweigh these negatives.

Akin to the Dos Equis commercial that describes “The Most Interesting Man in the World,” I’d describe the profession of anesthesiology as “The Most Interesting Job in the World.”

And when you love your job, you’ll never work a day in your life.

ADVICE FOR PASSING THE ORAL BOARD EXAMS IN ANESTHESIOLOGY

THE ANESTHESIA CONSULTANT

As a faculty member on the Stanford Department of Anesthesiology, Perioperative and Pain Medicine, I enjoy the opportunity to give mock oral exams to the Stanford residents. First-year residents struggle mightily, while third-year residents are experienced and savvy. Taking six mock oral exams during a three-year anesthesia residency is valuable preparation for the real American Board of Anesthesiology exam. Based on decades of experience, here is my advice for passing the oral board exams in anesthesiology.

I’m not an American Board of Anesthesiology (ABA) Examiner, but I’ve been lucky enough to know a dozen or more ABA Examiners over many years. Twice a year at Stanford we provide mock-oral exams to the anesthesia residents to prepare them for when they officially take the real exam at the conclusion of their training.

You’ve heard that 20% of examinees fail the oral exam, and you’re worried. What should you do? The mock exams follow the exact format of the real  oral exam, and I’ve co-examined with experienced ABA examiners on multiple occasions. Here’s what I’ve learned from them, and what Stanford’s ABA examiners teach their residents about passing the Oral Board Exam in Anesthesiology.

Preparation:

  1. Read Miller’s Anesthesia cover to cover. Read it during your entire residency, and consider re-reading it in its entirety prior to taking the Exam.
  2. Be well-trained. Work hard during residency. Do challenging cases and read about those cases before and after the anesthetic. Attend the department lectures, and mortality and morbidity conferences.
  3. Download and memorize the algorithms in the Stanford Emergency Manual/Cognitive Aid for Perioperative Critical Events.
  4. Find board-certified anesthesiologists who are willing to give you mock-oral practice exams. It helps.

Taking the actual oral board exam test:

  1. Format: You will be tested in two 35-minute sessions, Part A and Part B. For each session, you will have two examiners, a Senior Examiner and a Junior Examiner. For each session, you will be given a stem question of a specific anesthetic case 10 minutes prior to the session. An example question might be something like: “A 50-year-old man, 120 kg, 6 feet tall, is scheduled for a cholecystectomy. He has ankylosing spondylitis, and uses an insulin pump to manage his diabetes. He has dyspnea on climbing one flight of stairs.”
  2. The format for Part A: The Senior Examiner will question you for 10 minutes on intraoperative management, then the Junior Examiner will question you for 15 minutes on postoperative management and critical care, and then the Senior Examiner will question you for 10 minutes on 3 or more additional topics.
  3. The format for Part B: The Senior Examiner will question you for 10 minutes on preoperative management, then the Junior Examiner will question you for 15 minutes on intraoperative management, and then the Senior Examiner will question you for 10 minutes on 3 or more additional cases. Your examiners for Part B will not be the same individuals who examined you in Part A.
  4. The stem questions and additional questions will be scripted to cover all aspects of anesthesiology, i.e. obstetrics, pediatric, neurosurgical, cardiac, pain, regional blocks, trauma, etc.
  5. You’ll get the stem question 10 minutes prior to entering the exam room. Use these 10 minutes of time to organize your thoughts. Take notes and formulate your anesthetic plan. Try to discern the biggest medical risks/pitfalls of this particular case, and make a plan to anticipate these risks.
  6. Examiners score each candidate in four qualities:  A. Application of Knowledge (Did you demonstrate that you not only knew facts, but that you applied them in a clinical scenario?), B. Judgment (Did you make sound decisions?), C. Adaptability (Were you able to change your plan in response to a changes in the situation or the patient’s condition?), and D. Organization and Presentation (How well did you communicate? Are you an anesthesia consultant?)
  7. Remember Airway-Breathing-Circulation, in that order. Don’t harm a patient by losing the airway. Know the ASA Difficult Airway Algorithm by heart.
  8. If the question relates to one of the 25 algorithms in the Stanford Emergency Manual/Cognitive Aid for Perioperative Critical Events, then explain exactly how you’d follow the steps in the Manual.
  9. Imagine yourself in the OR actually doing the case, and explain exactly what you would normally do and why. Don’t follow a plan you would never take in actual practice.
  10. Try not to ask questions. Use your time to answer questions.
  11. There is no one right answer for most clinical scenario questions. Just be prepared to justify why you chose the plan you chose.
  12. Expect bad things (complications) to happen to your patients. Don’t be alarmed, the complications are written into the script. Tell the examiner what you would do.
  13. If you don’t know an answer, it’s better to say “I don’t know” than to blunder and guess.
  14. Make eye contact with the examiners throughout. Speak confidently and talk to them like a colleague.
  15. “Ringing the bell.” During your oral answers, your job is to “ring the bell” as  often as possible with pertinent facts of pharmacology, physiology, and medical knowledge pertinent to the case. Demonstrate what you know. Demonstrate that you can apply your knowledge, adapt to changes in clinical situations, use reasonable clinical judgment based on the information available, and present your ideas in a clear and organized manner.
  16. EXAMPLE STEM QUESTION:

“A 50-year-old man, 120 kg, 6 feet tall, is scheduled for a cholecystectomy. He has ankylosing spondylitis, and uses an insulin pump to manage his diabetes. He has dyspnea on climbing one flight of stairs.”

For this stem question, a Part B oral exam may proceed as follows:

I. First 10 minutes (preoperative management)

Expect questions such as:

  1. How would you work up the shortness of breath? Would you cancel the surgery? Why? Would you order pulmonary function tests? What do you know about pulmonary function tests? What is an FEV1?
  2. What is ankylosing spondylitis? What are the anesthetic risks?
  3. What would you do with the insulin therapy preoperatively? What types of insulin are there? How does insulin work in glycemic control? Would you stop the insulin pump? Continue it? Why? How tightly will you control the glucose level preoperatively?
  4. Define morbid obesity. Is this patient morbidly obese? How does obesity affect pulmonary physiology? Discuss the anesthetic risks associated with morbid obesity.
  5. Do you need a cardiology consult preoperatively? Why? Why not?
  6. The surgeon tells you the surgery is urgent, and he can’t wait for a cardiology consult or a treadmill test before surgery. What do you tell the surgeon?

II. The next 15 minutes (Intraoperative management)

Expect questions such as:

  1. What monitors will you use for the surgery? Why? You are unable to insert an art line. What will you do?
  2. How would you induce anesthesia? (If you chose to induce general anesthesia without an awake intubation, and you paralyze this patient, expect the examiner to give you an impossible intubation in this patient with ankylosing spondylitis. If mask ventilation is impossible, you will have a difficult rescue problem). Bottom line: this patient needs an awake intubation via a fiberoptic technique. Discuss how you’d do this.
  3. What maintenance anesthetic would you use? Why would you choose sevoflurane over isoflurane? What is MAC? How does the MAC vary with patient age?
  4. How often would you check blood glucose levels? The glucose concentration is 495 mg/dL, what would you do? The glucose concentration drops to 33 mg/dL, what would you do?
  5. The oxygen saturation drops to 85% intraoperatively. What would you do, both diagnostically and therapeutically?
  6. The intraoperative blood pressure drops to 65/35. What would you do? What diagnostic interventions, if any? What therapies? How does ephedrine work? How does phenylephrine work?
  7. The heart rate increases to 150 beats per minute. What would you do? What diagnostic interventions, if any? What therapies? The heart rate drops to 30 beats per minute. What would you do? What diagnostic measures, if any? What therapies?

III.  The final 10 minutes (examples of 3 additional cases):

  1. A preeclamptic woman presents for an urgent Cesarean section. She has a blood pressure of 160/100 and platelet count of 30,000. How would you do the anesthetic? Would you do a spinal? An epidural? Why or why not? If you do a general anesthetic, how will you manage her blood pressure?
  2. A 2-year-old boy presents for surgery. He has an open eye injury and a full stomach. How will you induce anesthesia? Will you start an awake IV? Will you do a mask induction? What are the risks of each?
  3. An 89-year-old woman with end-stage-renal-disease presents at 1 a.m. for emergency bowel obstruction surgery. Her last hemodialysis was four days ago. How will you manage her renal disease? Will you delay surgery to dialyze her? The surgeon tells you that delaying surgery will result in her dying of sepsis. How will you proceed?

Additional advice:

In addition to reading Miller’s Anesthesia twice, read through the Clinical Cases for Anesthesia Professionals in theanesthesiaconsultant.com, and follow the guidelines I’ve outlined in these cases.

SEVEN DEADLY DRUGS IN AN ANESTHESIOLOGIST’S DRAWER

THE ANESTHESIA CONSULTANT

As anesthesiologists we are the only physicians who routinely prescribe and administer injectable medications ourselves. Most physicians write orders for medications. Registered nurses then administer the medications on hospital wards, in intensive care units, in emergency rooms, and in clinics. As anesthesiologists we have our own drug cart, stocked with dozens of medications, including hypnotics, paralyzing drugs, cardiovascular drugs, antibiotics, anti-nausea drugs, anti-inflammatory drugs, and resuscitation drugs. There are Seven Deadly Drugs in an anesthesiologist’s drawer.

drug ampoules in an anesthesia drawer

Typically, we make a decision to inject a drug, then open the ampoule, draw the contents of the ampoule into a syringe, and inject it into the patient … without the approval, input, or monitoring of any other healthcare provider.

Do medication errors occur? Yes they do, because anesthesiologists are human, and to err is human. In a survey conducted in Japan between 1999 and 2002 in more than 4,291,925 cases, the incidence of critical incidents due to drug administration error was 18.27/100,000 anesthetics. Cardiac arrest occurred in 2.21 patients per 100,000 anesthetics. Causes of death were overdose or selection error involving non-anesthetic drugs, 47.4%; overdose of anesthetics, 26.3%; inadvertent high spinal anesthesia, 15.8%; and local anesthetic intoxication, 5.3%. Ampoule or syringe swap did not lead to any fatalities. (Irita K, et al. Critical incidents due to drug administration error in the operating room: an analysis of 4,291,925 anesthetics over a 4 year period. Masui 2004; 53(5):577–84. )

In a South African study of 30,412 anaesthetics, anaesthetists reported a combined incidence of one error or near-miss per 274 cases. Of all errors, 36.9% were due to drug ampoule misidentification; of these, the majority (64.4%) were due to similar looking ampoules. Another 21.3% were due to syringe identification errors. No major complication attributable to a drug administration error was reported. (Llewellyn RL, et al. Drug administration errors: a prospective survey from three South African teaching hospitals. Anaesth Intensive Care 2009 ; 37(1):93–8. )

What can be done to eliminate or minimize medication errors? A Japanese study examined the value of color-coding syringes, as follows: blue syringes contained local anesthetics; yellow syringes, sympathomimetic drugs; and white-syringes with a red label fixed opposite the scale, muscle relaxants. Although five syringe swaps were recorded from February 2003 to January 2004 in 5901 procedures prior to the change, they encountered no syringe swaps from February 2004 to January 2005 in 6078 procedures performed after switching to color-coded syringes (P <0.05). (Hirabayashi Y, et al. The effect of colored syringes and a colored sheet on the incidence of syringe swaps during anesthetic management. Masui 2005; 54(9):1060–2.)

Published evidence-based practices to reduce the risk of medication error include the following recommendations:

  1. The label on any drug ampoule or syringe should be read carefully before a drug is drawn up or injected;
  2. The legibility and contents of labels on ampoules and syringes should be optimized according to agreed standards; syringes should always be labeled; formal organization of drug drawers and workspaces should be used;
  3. Labels should be checked with a second person or a device before a drug is drawn up or administered. (Note: this is impractical in the anesthesia world.)
  4. Dosage errors are particularly common in pediatric patients. Technological innovations, including the use of bar codes and various cognitive aids, may facilitate compliance with these recommendations. (Merry AF, Anderson BJ. Medication errors–new approaches to prevention. Paediatr Anaesth 2011; 21(7):743–53.)

Bar-code medication administration (BCMA) systems exist for anesthesiologists to identify the ampoule of each drug at the time of administration. I’m not seeing these devices in widespread use in the United States yet. A pilot study in Great Britain perceived that bar-code readers contributed to the prevention of drug errors. The study concluded that the  technological aspects of its integration into the operating theatre environment, and learning, will require further attention. (Evley R. Confirming the drugs administered during anaesthesia: a feasibility study in the pilot National Health Service sites, UK. Br J Anaesth 2010; 105(3):289–96.)

In addition to the data from the aforementioned publications on the incidences of medication errors, how many medication errors go unpublished and unreported? Many anesthesiologists I know have shared their tales of medication errors, all of which are unpublished and unreported in the medical literature. Some swaps and errors will be inconsequential. Some swaps and errors will prolong an anesthetic, such as when a muscle relaxant paralyzes a patient at an unintended time or dose. Some swaps and errors contain the potential for dire complications.

The ancient Christian world identified Seven Deadly Sins. They were wrath, greed, sloth, pride, lust, envy, and gluttony. There exist at least seven medications that an anesthesiologist must strive to never inject intravenously in error. I call these the Seven Deadly Drugs.  All are present in the anesthesiologists’ drug drawer or at the operating room pharmacy. They are as follows:

  1. Epinephrine (1mg/1ml ampoule). Epinephrine is an important drug during ACLS to treat asystole and refractory ventricular fibrillation, to treat anaphylaxis, or to be used as an infusion to treat decreased cardiac output. This ampoule is routinely stocked in most drug drawers. If one injects it in error into a healthy patient, major hypertension and tachycardia will ensue.  Think blood pressures in the 250/150 range, and heart rates approaching 200 beats per minute. This can be lethal in elderly patients, or in patients with diminished cardiac reserve.
  2. Phenylephrine (10 mg/1 ml ampoule). Phenylephrine, when injected in 100-microgram doses or used as a dilute infusion, is an important drug to treat hypotension. This ampoule is routinely stocked in most drug drawers. If one injects it in error into a healthy patient, major hypertension will ensue, as well as reflex bradycardia.  Think blood pressures in the 250/150 range, and heart rates dropping below 50 beats per minute. This can be lethal in elderly patients, or patients with diminished cardiac reserve.
  3. Nitroprusside (50 mg/2ml) Nitroprusside, when diluted into an infusion, is an important drug to treat hypertension. If this ampoule is injected undiluted, the patient will experience rapid arterial vasodilation and severe hypotension.
  4. Insulin (100 Units/1ml, 10 ml vial). Insulin is an important medication to treat hyperglycemia. Typical doses range from 5–30 Units, which is a mere 1/20th to 3/10th of one milliliter. An erroneous injection of an insulin overdose to an anesthetized patient can result in severe hypoglycemia and brain death.
  5. Potassium Chloride (20 Meq/10 ml). Potassium chloride is an important treatment for hypokalemic patients. If it is administered erroneously as a bolus, potassium chloride can cause severe ventricular arrhythmias and death.
  6. Heparin (1000 U/ml). Heparin is an important anticoagulant, used routinely in open heart surgery and vascular surgery. If it is administered in error, it can cause unexpected bleeding during surgery.
  7. Isoproterenol (1 mg/5 ml) Isoproterenol can be used as a dilute infusion to increase heart rate in critically ill patients.  One of the hospitals I work at includes an ampoule of isoproterenol in the routine drug drawer, next to ampoules of common medications such as ketorolac (Toradol), hydrocortisone, and promethazine (Phenergan). If one injects a bolus of isoproterenol in error into a healthy patient, major tachycardia and hypertension will ensue. This can be lethal in elderly patients, or patients with diminished cardiac reserve.

What can anesthesiologists do to eliminate the risks of erroneously bolus injecting the Seven Deadly Drugs? This author recommends elimination of major vasopressor drugs such as epinephrine, phenylephrine, and isoproterenol and major vasodilators such as nitroprusside from routine drug drawers. This author recommends elimination of the potent anticoagulant heparin from routine drug drawers. Insulin is routinely sequestered in an operating room refrigerator, and most hospitals have protocols that insulin doses be double-checked by two medical professionals prior to injection. Potassium chloride is routinely sequestered the operating room pharmacy as well, distanced from the anesthesiologist’s routine drug drawer.

Above all, anesthesia practitioners need to be vigilant of the risk of picking up the wrong drug ampoule in error. Read the labels of your ampoules carefully, and take care not to inject any of the Deadly Seven Drugs.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

KEEPING ANESTHESIA SIMPLE: THE KISS PRINCIPLE

THE ANESTHESIA CONSULTANT

Clinical Cases:  You’re scheduled to anesthetize a 70-year-old man for a carotid endarterectomy, a 50-year-old man for an arthroscopic rotator cuff repair, and a 30-year-old woman for an Achilles tendon repair.  What anesthetics would you plan? “Keep It Simple, Stupid…” The KISS principle applies in anesthesiology, too.

 

Discussion:  In 1960, U.S. Navy aircraft engineer Kelly Johnson coined the KISS Principle, an acronym for “Keep It Simple, Stupid.” The KISS principle supports that most systems work best if they are kept simple rather than made complex. Simplicity should be a key goal in design, and unnecessary complexity should be avoided. The KISS Principle likely found its origins in similar concepts such as Occam’s razor, Leonardo da Vinci‘s “Simplicity is the ultimate sophistication,” and architect Mies Van Der Rohe‘s “Less is more.”

Let’s look at the three cases listed above.  For the carotid surgery, you choose an anesthetic regimen based on dual infusions of propofol and remifentanil, aiming for a rapid wake-up at the conclusion of surgery.  For the arthroscopic rotator cuff repair, you fire up the ultrasound machine and insert an interscalene catheter preoperatively.  After you’ve inserted the catheter, you induce general anesthesia with propofol and maintain general anesthesia with sevoflurane.  For the Achilles repair, you perform a popliteal block preoperatively.  After you’ve performed the block, you induce general anesthesia with propofol, insert an endotracheal tube, turn the patient prone, and maintain general anesthesia with sevoflurane and nitrous oxide.

All three cases proceed without complication.

Ten miles away, an anesthesiologist in private practice is scheduled to do the same three cases.  For each of the three cases she chooses the same anesthetic regimen:  Induction with propofol, insertion of an airway tube (an endotracheal tube for the carotid patient, and a laryngeal mask airway for the shoulder patient and the ACL patient, and an endotracheal tube for the prone Achilles repair), followed by sevoflurane and nitrous oxide for maintenance anesthesia and a narcotic such as fentanyl titrated in as needed for postoperative analgesia.  The carotid patient is monitored with an arterial line, and vasoactive drugs are used as necessary to control hemodynamics.

“Wait a minute!” you say. “Elegant anesthesia requires advanced techniques for different surgeries. Why would a private practitioner do all three cases with nearly identical choices of drug regimen?  Why would a private practitioner fail to tailor their anesthetic plan to the surgical specialty? Total intravenous anesthesia and ultrasound-guided regional anesthesia are important arrows in the quiver of a 21st-century anesthesiologist, aren’t they?”

In my first week in private practice, just months after graduating from the Stanford anesthesia residency program, the anesthesia chairman at my new hospital emphasized relying on the KISS Principle in anesthesia practice.  He stressed that the objective of clinical anesthesia wasn’t to make cases interesting and challenging, but to have predictable and complication-free outcomes. Exposing a patient to extra equipment (two syringe pumps), or two anesthetics (regional plus general) instead of general anesthesia alone, adds layers of complexity, and defies the KISS principle.

There are no data indicating that using two syringe pumps and total intravenous anesthesia will produce a better outcome than turning on a sevoflurane vaporizer.  There are no data demonstrating that combining a regional anesthetic with a general anesthetic for shoulder arthroscopy or Achilles tendon surgery will improve long-term outcome.

The KISS principle opines that most systems work best if they are kept simple rather than made complex, and doing two anesthetics instead of one adds complexity.  I’ve learned that an anesthesiologist should choose the simplest technique that works for all three parties:  the surgeon, the patient, and the anesthesiologist. The hierarchy from most simple to complex might look something like this:  (1) local anesthesia alone, (2) local plus conscious sedation, (3) a regional block plus conscious sedation, (4) general anesthesia by mask, (5) general anesthesia with a laryngeal mask airway, (6) general anesthesia with an endotracheal tube, or (7) general anesthesia plus regional anesthesia combined.  The combination of drugs used should be as minimal and simple as possible.

If all three parties (the surgeon, the patient, and the anesthesiologist) are okay with the patient being awake for a particular surgery, then the simplest of the first three options can be selected.  If any one or all of the three parties wants the patient unconscious, then the simplest option of (4) – (7) can be selected.

I’m not an opponent of regional anesthesia.  Ultrasound-guided regional anesthesia is a significant advance in our specialty for appropriate cases, and substituting regional anesthesia for a general anesthetic is a reasonable alternative. Compared with general anesthesia, peripheral nerve blocks for rotator cuff surgery have been associated with shorter discharge times, reduced need for narcotics, enhanced patient satisfaction, and fewer side effects (Hadzic A, Williams BA, Karaca PE, et al.: For outpatient rotator cuff surgery, nerve block anesthesia provides superior same-day recovery after general anesthesiaAnesthesiology  2005; 102:1001-1007). On the other hand, meta-analysis has demonstrated no long-term difference in outcome between regional and general anesthesia for ambulatory surgery.  (Liu SS, Strodtbeck WM, Richman JM, Wu CL: A comparison of regional versus general anesthesia for ambulatory anesthesia: A meta-analysis of randomized controlled trialsAnesth Analg  2005; 101:1634-1642). Why perform combined regional anesthesia plus general anesthesia for minor surgeries?  Are we doing regional blocks just to showcase our new ultrasound skills? If there is an ultrasound machine in the hallway and an ambulatory orthopedic patient on the schedule, these two facts alone are not an indication for a regional block. Patients receive an extra bill for the placement of an ultrasound-guided block, and economics alone should never be a motivation to place a nerve block.

In a painful major orthopedic surgery such as a total knee replacement or a total hip replacement, a regional block can improve patient comfort and outcome. This month’s issue of Anesthesiology a retrospective review of nearly 400,000 patients who had total knee or total hip replacement.  Compared with general anesthesia, neuroaxial anesthesia is associated with an 80% lower 30-day mortality and a 30 – 80% lower risk of major complications (Memtsoudis et al., Perioperative Comparative Effectiveness of Anesthetic Technique in Orthopedic Patients, Anesthesiology. 118(5):1046-1058, May 2013).

Many outpatient orthopedic surgeries performed under straight general anesthesia require only modest oral analgesics afterward.  I had general anesthesia for a shoulder arthroscopy and subacromial decompression last month, and required no narcotic analgesics post-op.  If I’d had an interscalene block, the anesthesiologist could have attributed my comfort level to the placement of the block.  No block was necessary.

Achilles repairs don’t require a combined regional–general anesthetic. Achilles repairs simply don’t hurt very much. One surgeon in our practice does his Achilles repairs under local anesthesia with the patient awake, and the cases go very smoothly.  Other surgeons in our practice insist that a popliteal block be placed prior to general anesthesia for Achilles repairs, a dubious decision because (a) it defies the KISS Principle, and (b) the surgeon has no expertise in dictating anesthetic practice.

Every peripheral nerve block carries a small risk. Although serious complications are unusual, risks include falling; bleeding; local tissue injury, pneumothorax; nerve injury resulting in persistent pain, numbness, weakness or paralysis of the affected limb; or local anesthetic toxicity.  Systemic local anesthetic toxicity occurs in 7.5–20 per 10,000 peripheral nerve blocks (Corman SL et al., Use of Lipid Emulsion to Reverse Local Anesthetic-Induced Toxicity, Ann Pharmacother 2007; 41(11):1873-1877).

Use the simplest anesthetic that works.  Assess whether combined regional–general anesthetics are necessary or wise.  I realize that complex anesthetic regimens are routine aspects of a solid training program, because residents need to leave their training program with a mastery of multiple skills.  But once you’re in private practice, my advice is to take heed of the KISS Principle.

SHOULD YOU CANCEL SURGERY FOR A BLOOD PRESSURE OF 170/99?

THE ANESTHESIA CONSULTANT

Clinical Case for Discussion:  This month’s question is on hypertension and anesthesia. You are scheduled to anesthetize a 71-year-old male for an arthroscopic rotator cuff repair.  His blood pressure when you meet him in pre-op is 170/99 mmHg.  The nurses and the surgeon are alarmed.  What would you do? Should you cancel surgery for a blood pressure of 170/99?

Discussion:  You assess the patient carefully.  A review of his chart shows he’s been taking anti-hypertensive oral medications for ten years.  His current regimen includes daily atenolol and lisinopril, with his most recent doses taken this morning with a sip of water.  He was seen in his internist’s office one week ago, and the internist’s preoperative clearance note documents that at that time his blood pressure was 140/88.  He has no other medical comorbidities. His cardiac, renal, and neurologic histories are negative. He does not have diabetes. His BMI (Body Mass Index) is normal at 25. He walks three miles per day without shortness of breath.  His resting EKG and his BUN and creatinine are normal. In short, he has no signs that hypertension has caused end-organ damage to his heart, kidneys, or brain.

The patient’s physical exam is unremarkable except that he appears nervous.  Should you cancel the case and send him back to his internist to adjust the blood pressure medical therapy regimen?  Should you lower his blood pressure acutely with intravenous antihypertensive drugs, and then proceed with the surgery?

Hypertension, defined as two or more blood pressure readings greater than 140/90 mm Hg, is a common affliction found in 25% of adults and 70% of adults over the age of 70 (Miller’s Anesthesia, 9th Edition, Chapter 31, Preoperative Evaluation). Over time, hypertension can cause end-organ damage to the heart, arterial system, and kidneys. Hypertensive and ischemic heart disease are the most common types of organ damage associated with hypertension.  Anesthesiologists are always wary of cardiac complications in hypertensive patients.

Chronic hypertension is a serious health hazard.  But what about a single elevated blood pressure value prior to elective surgery?

Per Miller’s Anesthesia, “while preoperative hypertension is associated with an increased risk of cardiovascular complication, this association is generally not evident for systolic blood pressure values less than 180 mm Hg or diastolic blood pressure values less than 110 mm Hg. Additionally, there is no compelling data that delaying surgery to optimize blood pressure control will result in improved outcomes.”

Note that this is in the setting of elective surgery in a patient who has no end-organ damage to his or her heart, kidneys, or brain. A patient with  shortness of breath, angina, elevated BUN/Creatine, decreased glomerular filtration rate, or symptoms of a cerebral vascular accident, would pose a significant risk during the elective induction of general anesthesia.

For emergency or urgent surgery, per Miller’s Anesthesia, “anesthesiologists should weigh the potential benefits of delaying surgery to optimize antihypertensive treatment against the risks of delaying the procedure.” What if a patient presents for urgent surgery for acute cholecystitis and his blood pressure is 190/118 mm Hg?  For urgent or emergent surgery, consider titrating intravenous antihypertensive drugs such as labetolol (5–10 mg q 5–10 minutes prn) or hydralazine (5–10 mg q 5–10 minutes prn) to decrease blood pressure prior to initiating anesthesia.  Because the eventual induction of general anesthesia with intravenous and volatile anesthetics will lower blood pressure by vasodilation and cardiac depression, and can destabilize the patient, any pre-induction antihypertensives must be titrated with great care.  Once doses of labetolol or hydralazine are injected, there is no way to remove the effect of that drug.  For critically ill patients, consider monitoring with a preoperative arterial line and infusing a more titratable and short-acting drug such as nitroprusside or nitroglycerine for blood pressure control.

Let’s return to the anesthetic for your elective shoulder surgery patient with the blood pressure of 170/99 mmHg. You begin by administering 2 mg of midazolam IV.  Three minutes later his blood pressure decreases to 160/90.  You anesthetize him with 50 micrograms of fentanyl, 140 mg of propofol IV, and 30 mg of rocuronium, and intubate the trachea.  In the next 20 minutes, while the patient is moved into a lateral position for the surgery, his blood pressure drops to 95/58. Because most anesthetics depress blood pressure by vasodilation or cardiac depression, it’s common for patients such as this one to require intermittent vasopressors to avoid hypotension, especially at moments when surgical stimulus is minimal. A common recommendation is to maintain intraoperative arterial pressure within 20% of the preoperative arterial pressure.  This recommendation can be a challenge, especially if the preoperative blood pressure was elevated.  A 20% reduction from 170/99 (mean pressure = 122 mm Hg) would be 136/79.  A 20% reduction from the mean pressure of 122 mm Hg would be a mean pressure of 98 mm Hg.  You choose to treat the patient’s hypotension with 10 mg of IV ephedrine, which raises the blood pressure to 140/85.  Fifteen minutes later, the surgeon makes his incision, and the blood pressure escalates to 180/100.  You treat this by deepening anesthesia with small, incremental doses of fentanyl and propofol.  The surgery concludes, you awaken the patient without complications, and his blood pressure in the Post Anesthesia Care Unit is 150/88 mm Hg.

This pattern of perioperative blood pressure lability is common in hypertensive patients, and will require your vigilance to avoid extremes of hypotension or hypertension.

THE ANESTHESIA CONSULTANT

In the United States, will you have an anesthesiologist for your wisdom teeth extraction surgery? If you are a healthy patient, the answer is: probably not.

In the United States, oral surgeons perform most wisdom teeth extraction surgeries.  This is a very common surgery, with the operation performed on up to five million times in the United States each year. Most patients are healthy teenagers.  Oral surgeons perform wisdom teeth surgeries in their office operating rooms, and most oral surgeons manage the intravenous sedation anesthesia themselves, without the aid of an anesthesiologist.

Oral surgeons are trained in the airway management and general anesthesia skills necessary to accomplish this safely, and a nurse assists the oral surgeon in delivering sedative medications.  Oral surgeons must earn a license to perform general anesthesia in their office. To administer general anesthesia in an office, most oral surgeons complete at least three months of hospital-based anesthesia training. In most states, oral surgeons then undergo an in-office evaluation by a state dental-board-appointed examiner, who observes an actual surgical procedure during which general anesthesia is administered to a patient. It’s the examiner’s job to inspect all monitoring devices and emergency equipment, and to test the doctor and the surgical staff on anesthesia-related emergencies. If the examinee successfully completes the evaluation process, the state dental board issues the doctor a license to perform general anesthesia.  Note that even though the oral surgeon has a license to direct anesthesia, the sedating drugs he or she orders are often administered by a nurse who has no license or training in anesthesia.

In an oral surgeon’s office, general anesthesia for wisdom teeth extraction typically includes intravenous sedation with several drugs:  a benzodiazepine such as midazolam, a narcotic such as fentanyl or Demerol, and a hypnotic drug such as propofol, ketamine, and/or methohexital.  Prior to administering these powerful drugs, the oral surgeon must be certain that he or she can manage the Airway and Breathing of the patient. After the patient is asleep, the oral surgeon injects a local anesthetic such as lidocaine to block the superior and inferior alveolar nerves.  These local anesthetic injections render the mouth numb, so the surgeon can operate without inflicting pain.  Typically, no breathing tube is used and no potent anesthetic vapor such as sevoflurane is used.  The oral surgeon may supplement intravenous sedation with inhaled nitrous oxide.

The oral surgeon has all emergency airway equipment, breathing tubes, and emergency drugs available. The safety record for oral surgeons using these methods seems excellent.  My review of the National Institutes of Health website PubMed reveals very few instances of death related to wisdom teeth extraction.  Recent reports include one patient who died in Germany due to a heart attack after his surgery (Kunkel M, J Oral Maxillofac Surg. 2007 Sep;65(9):1700-6.  Severe third molar complications including death-lessons from 100 cases requiring hospitalization).  A second patient died in Japan because of a major bleed in his throat occluding trachea, one day after his surgery (Kawashima W, Forensic Sci Int. 2013 May 10;228(1-3):e47-9. doi: 10.1016/j.forsciint.2013.02.019. Epub 2013 Mar 26. Asphyxial death related to postextraction hematoma in an elderly man).

Most oral surgeons do not publish their mishaps or complications, so the medical literature is not the place to search for data on oral surgery deaths. Deaths that occur during or after wisdom teeth extraction are sometimes reported in the lay press.  In April 2013, a 24-year-old healthy man began coughing during his wisdom teeth extraction in Southern California, and went into cardiac arrest.  He was transferred to a hospital, where he died several days later.

In 2011, a Baltimore-area teen died during wisdom teeth extraction. The family’s malpractice claim was settled out of court in 2013.

Every general anesthetic carries a small risk, such as these two reported cases of death following wisdom teeth extractions.  All acute medical care involves attending to the A – B – C ‘s of Airway, Breathing, and Circulation.  During surgery for wisdom teeth extraction, the oral surgeon is operating in the patient’s mouth. Surgery in the mouth increases the chances that the operation will interfere with the patient’s Airway or Breathing.  The surgeon’s fingers, surgical instruments, retractors, and gauze pads crowd into the airway, and may influence breathing.  If the patient’s breathing becomes obstructed, altering the position of the jaw, the tongue, or the neck is more challenging than when surgery does not involve the airway.

I’ve attended to hundreds of patients for dental surgeries.  For dental surgery in a hospital setting, anesthesiologists commonly insert a breathing tube into the trachea after the induction of general anesthesia.  A properly positioned tracheal tube can assure the Airway and Breathing for the duration of the surgery.  Because an anesthesiologist is not involved with performing the surgery, his or her attention can be 100% focused on the patient’s vital signs and medical condition.  When anesthesiologists are called on to perform general anesthesia for wisdom teeth extraction in a surgeon’s office, we typically use a different anesthetic technique.  Usually there is no anesthesia machine to deliver potent inhaled anesthetics, therefore intravenous sedation is the technique of choice.  Usually no airway tube is inserted.  When general anesthesia is induced in an office setting, the patient must have an adequate airway, i.e. and American Society of Anesthesiologists Class I or II airway. A typical technique is a combination of intravenous midazolam, fentanyl, propofol, and/or ketamine.  Oxygen is administered via the patient’s nostrils throughout the surgery. The adequacy of breathing is continuously monitored by both pulse oximetry and end-tidal carbon dioxide monitoring.  The current American Society of Anesthesiologist Standards for Basic Anesthetic Monitoring (July 1, 2011) state that “Every patient receiving general anesthesia shall have the adequacy of ventilation continually evaluated. … Continual monitoring for the presence of expired carbon dioxide shall be performed unless invalidated by the nature of the patient, procedure or equipment.”

The motto of the American Society of Anesthesiologists is “Vigilance.”  If the patient’s oxygen saturation and/or end-tidal carbon dioxide numbers begin to decline, an anesthesiologist will act immediately to improve the A – B – C ‘s of Airway, Breathing, and Circulation.

Let’s return to our opening question: Will you have an anesthesiologist for your wisdom teeth extraction surgery?  If you are a healthy patient, I cannot show you any data that an anesthesiologist provides safer care for wisdom teeth surgery than if an oral surgeon performs the anesthesia. The majority of wisdom teeth extractions in the United States are performed on healthy patients without an anesthesiologist, and reported complications are rare.  If you want an anesthesiologist, you need to make this clear to your oral surgeon, and ask him to make the necessary arrangements.  If you do choose to enlist a board-certified anesthesiologist for your wisdom teeth extractions, know that your anesthesia professional has completed a three or four year training program in his field, and is expert in all types of anesthesia emergencies.  As a downside, you will be responsible for an extra bill for the professional fee of this anesthesiologist.

Whether an anesthesiologist or an oral surgeon attends to your anesthesia, the objectives are the same:  Each will monitor the A – B – C ‘s of your Airway, Breathing, and Circulation to keep you oxygenated and ventilated, so you can wake up and leave that dental office an hour or so after your wisdom teeth extraction surgery has concluded.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

THE ANESTHESIA CONSULTANT

You choose the car you drive, the apartment you rent, the smart phone in your pocket, and the flavor of ice cream among 31 flavors at Baskin-Robbins.  Most of you  choose your family physician, your dermatologist, and your surgeon.  But can you choose your anesthesiologist?

 

It depends.

To answer the question, let’s look at how anesthesia providers are assigned for each day of surgery.

Who makes the decision as to which anesthesia provider is assigned to your case? The anesthesia service at every hospital or healthcare system will have a scheduler.  This scheduler is an individual (usually an anesthesiologist) who surveys the list of the surgical cases one day ahead of time.  There will be multiple operating rooms and multiple cases in each operating room. Each operating room is usually scheduled for six to ten hours of surgical cases.  The workload could vary from one ten-hour case to eight shorter cases.  The total number of operating rooms will vary from hospital to hospital.  Typically each room is specialty-specific, that is, all the cases in each room are the same type of surgery.  The scheduler will an assign appropriate anesthesia provider to each room, depending on the skills of the anesthesia provider and the type of surgery in that room.

There are multiple surgical specialties and multiple types of anesthetics.  An important priority is to schedule an anesthesia provider who is skilled and comfortable with the type of surgery scheduled.  An open-heart surgery will require a cardiac anesthesiologist.  A neonate (newborn) will require a pediatric anesthesiologist.  Most surgeries, e.g., orthopedic, gynecologic, plastic surgery, ear-nose-and-throat, abdominal, urologic, obstetric, and pediatric cases over age one, are bread-and-butter anesthetics that can be handled by any well-trained provider.

Each day certain anesthesiologists are “on-call.”  When an anesthesiologist is on-call, he or she is the person called for emergency add-on surgeries that day and night.  The on-call anesthesiologist is expected to work the longest day of cases, and the scheduler will usually assign that M.D. to an operating room with a long list of cases.  If you have emergency surgery at 2 a.m., you will likely be cared for by the on-call anesthesiologist.  A busy anesthesia service may have a first-call, a second-call, and a third-call anesthesiologist, a rank order that defines which anesthesia provider will do emergency cases if two or three come in simultaneously.  A busy anesthesia service will have on-call physicians in multiple specialties, i.e., there will be separate on-call anesthesiologists for cardiac cases, trauma cases, transplant cases, and obstetric cases.

Different hospitals have different models of anesthesia services.  In parts of the United States, especially the Midwest, the South, and the Southeast, the anesthesia care team is a common model.  An anesthesia care team consists of both certified registered nurse anesthetists (CRNA’s) and M.D. anesthesiologists.  For complex cases such as cardiac cases or brain surgeries, an M.D. anesthesiologist may be assigned as the solitary anesthesia provider.  For simple cases such as knee arthroscopies or breast biopsies, the primary anesthesia provider in each operating room will be a CRNA, with one M.D. anesthesiologist serving as the back-up consultant for up to four rooms managed by CRNA’s.

In certain states, the state governor has opted out of the requirement that an M.D. anesthesiologist must supervise all CRNA-provided anesthesia care.  In these states, a CRNA may legally provide anesthesia care without a physician supervising them.  Currently, the seventeen states that have opted out of physician supervision of CRNA’s include Alaska, California,  Colorado, Iowa, Idaho, Kansas, Kentucky, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oregon, South Dakota, Washington, and Wisconsin.  In some hospitals in these states, your anesthesia provider may be an unsupervised nurse anesthetist, not a doctor at all.

Some hospitals have only M.D. anesthesiologists who personally do all the cases.

Academic hospitals, or university hospitals, have residents-in-training who administer most of the anesthetic care.  In academic hospitals, faculty members supervise anesthesia residents in a ratio of one faculty to one resident or one faculty to two residents.

Can a surgeon request a specific anesthesia provider?  Yes.  At times, a surgeon may have certain anesthesia providers that he or she requests and uses on a regular basis.  It’s far easier for a surgeon to request a specific anesthesia provider than it is for you to do so.

The assignment of your anesthesia provider is usually made by the scheduler on the afternoon prior to surgery, and you the patient will have little or no say in the matter. If you are like most patients, you have no idea who is an excellent anesthesia provider and who is less skilled. You won’t find much written about anesthesiologists on Yelp, Healthgrades, or other consumer social-media websites.  Most patients don’t even remember the name of their anesthesia provider unless something went drastically wrong.  Such is the nature of our specialty.  Your anesthesia provider will spend a mere ten minutes with you while you’re awake, and during those ten minutes your mind will be reeling with worries about surgical outcomes and risks of anesthesia.  The anesthesia provider’s name is not a high priority.  After the surgery is over, anesthesiologists are a distant memory.

What if your next-door neighbor is an anesthesiologist whom you respect?  What if you are scheduled for surgery at his hospital or surgery center, and you want him to take care of you?  Can this be arranged?  Most likely, it can.  The best plan for requesting a specific anesthesiologist is to have the anesthesiologist work the system from the inside, several days prior to your surgery date.  He will talk to the scheduler and make sure that he is assigned into the operating room list that includes your surgery.  You’ll be happy and reassured to see him on the day of surgery, and he’ll likely be happy to take care of you.  Anesthesiologists love to be requested by patients.  It makes us feel special.  Doctors aspire to be outstanding clinicians, and a request from a specific patient validates that we are unique.

As you can see, the decision of who is assigned to be the anesthesia provider for your surgery is a multifaceted process. Your best strategy for requesting a specific anesthesiologist is to (1) contact the anesthesiologist yourself and ask that he or she contact anesthesia scheduling and make sure that he or she is scheduled to do your case, or (2) contact your surgeon and ask your surgeon if they can arrange to have the specific anesthesia provider that you request.

DOES REPEATED GENERAL ANESTHESIA HARM THE BRAINS OF INFANTS AND YOUNG CHILDREN?

THE ANESTHESIA CONSULTANT

Recent scholarly publications have raised the question whether repeated exposure to general anesthesia is harmful to the developing brain in infants and young children.  Millions of children have surgery under general anesthesia each year. Is repeated exposure to general anesthesia safe for the developing brain of your child? Let’s look at the evidence.

pediatric anesthesia

In 2011, a retrospective Mayo Clinic study looked at the incidence of learning disabilities (LDs) in a cohort of children born in Olmsted County, Minnesota, from 1976 to 1982.  Among the 8,548 children analyzed, 350 of the children received general anesthesia before the age of 2.  A single exposure to general anesthesia was not associated with an increase in LDs, but children who had two or more anesthetics were at increased risk for LDs.  The study concluded that repeated exposure to anesthesia and surgery before the age of 2 was a significant independent risk factor for the later development of LDs.  The authors could not exclude the possibility that multiple exposures to anesthesia and surgery at an early age adversely affected human neurodevelopment with lasting consequences.

The same group of Mayo Clinic researchers looked at the incidence of attention-deficit/hyperactivity disorder (ADHD) in children born from 1976 to 1982 in Rochester, Minnesota.  Among the 5,357 children analyzed, 341 ADHD cases were identified.  For children with no exposure anesthesia before the age of 2 years, the cumulative incidence of ADHD at age 19 years was 7.3%  Exposure to multiple procedures requiring general anesthesia was associated with an increased cumulative incidence of ADHD of 17.9%. The authors concluded that children repeatedly exposed to procedures requiring general anesthesia before age 2 years were at increased risk for the later development of ADHD.

Anesthesia scientists decided to study this problem in mice.  In March 2013, researchers at Harvard and other hospitals exposed 6- and 60-day-old mice to various anesthetic regimens. The authors then determined the effects of the anesthesia on learning and memory function, and on the levels of proinflammatory chemicals such as cytokine interleukin-6 in the animals’ brains. The authors showed that anesthesia with 3% sevoflurane for 2 hours daily for 3 days induced cognitive impairment (i.e., unusually poor mental function) and neuroinflammation (i.e., elevated levels of brain inflammatory chemicals such as interleukin-6) in young but not in adult mice. Anesthesia with 3% sevoflurane for 2 hours daily for 1 day or 9% desflurane for 2 hours daily for 3 days caused neither cognitive impairment nor neuroinflammation. Treatment with the non-steroidal anti-inflammatory (NSAID) drug ketorolac caused improvement in the sevoflurane-induced cognitive impairment. The authors concluded that anesthesia-induced cognitive impairment may depend on age, the specific anesthetic agent, and the number of exposures. The findings also suggested that cellular inflammation in the brain may be the basis for the problem of anesthesia-induced cognitive impairment, and that potential prevention and treatment strategies with NSAIDs may ultimately lead to safer anesthesia care and better postoperative outcomes for children.

The same Harvard research group assessed the effects of sevoflurane on brain function in pregnant mice, and on learning and memory in fetal and offspring mice. Pregnant mice were treated with 2.5% sevoflurane for 2 hours and 4.1% sevoflurane for 6 hours. Brain tissues of both fetal and offspring mice were harvested and immunohistochemistry tests were done to assess interleukin-6 and other brain inflammatory levels.  Learning and memory functions in the offspring mice was determined by using a water maze. The results showed that sevoflurane anesthesia in pregnant mice induced brain inflammation, evidenced by increased interleukin-6 levels in fetal and offspring mice.  Sevoflurane anesthesia also impaired learning and memory in offspring mice. The authors concluded that sevoflurane may induce detrimental effects in fetal and offspring mice, and that these findings should promote more studies to determine the neurotoxicity of anesthesia in the developing brain.

What does all this mean to you if your children need anesthesia and surgery?  Although further studies and further data will be forthcoming, the current information suggests that:  (1) if your child has one exposure to anesthesia, this may constitute no increased risk to their developing brain, and (2) repeated surgery and anesthetic exposure to sevoflurane may be harmful to the development of the brain of children under 2 years of age.  It would seem a wise choice to delay surgery until your child is older if at all possible.

What does all this mean to anesthesiologists?  We’ll be watching the literature for new publications on this topic, but in the meantime it seems prudent to avoid exposing newborns and young children to repeated anesthetics with sevoflurane.  Currently, sevoflurane is the anesthetic of choice when we put children to sleep with a mask induction, because sevoflurane smells pleasant and it works fast.  Children become unconscious within a minute or two.  After a child is asleep, it may be advisable to switch from sevoflurane to the alternative gas anesthetic desflurane, since the Harvard study on mice showed anesthesia with 9% desflurane for 2 hours daily for 3 days caused neither cognitive impairment nor neuroinflammation.  A second alternative is to switch from sevoflurane to intravenous anesthetics alone, e.g., to utilize propofol and remifentanil infusions instead of sevoflurane.

The concept of pediatric anesthesia harming the developing brain was reviewed in the lay press in Time magazine in 2009.  The four articles I summarized above represent the most recent and detailed advances on this topic.  Stay tuned.  The issue of anesthetic risk to the developing brain will be closely scrutinized for years to come.

In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

THE ANESTHESIA CONSULTANT

 

Obese patients make anesthesiologists’ work more arduous.  Obese patients, especially morbidly obese and super obese patients, are at increased risk when they need surgery. Perhaps you’re overweight and you wish you weren’t. Your anesthesiologist wishes the same thing.  Let’s look at the reasons why.

Two hundred million Americans, or 65% of the U.S. adult population, are overweight or obese. Obesity as a disease is second only to smoking as a preventable cause of death.

The body mass index (BMI) has become the most widely applied classification tool used to assess individual weight status.  BMI is defined as the patient’s weight, measured in kilograms, divided by the square of the patient’s height, measured in meters.

A normal BMI is between 18.5 and 24.9.  Patients are considered to be overweight with a BMI between 25 and 29.9 obese with a BMI between 30 and 39.9, morbidly obese between 40 and 49.9, and super obese at greater than 50.

Morbid obesity is associated with far more serious health consequences than moderate obesity, and creates additional challenges for health care providers.  Between 2000 and 2010, the prevalence of morbid obesity in the U.S. increased by 70%, whereas the prevalence of super obesity increased even faster.  It’s estimated that in 2010, 15.5 million adult Americans, or 6.6% of the population, had an actual BMI >40, and carried the diagnosis of morbid obesity.

MEDICAL PROBLEMS ASSOCIATED WITH OBESITY

Obesity is an independent risk factor for heart disease, hypertension, stroke, hyperlipidemia, osteoarthritis, diabetes mellitus, cancer, and obstructive sleep apnea (OSA).  A neck circumference > 17 inches in men or > 16 inches cm in women is associated with obstructive sleep apnea. As a result of these concomitant conditions, obesity is also associated with early death.

There is a clustering of metabolic and physical abnormalities referred to as the “metabolic syndrome.” To be diagnosed with metabolic syndrome, you must have at least three of the following: abdominal obesity, elevated fasting blood sugar, hypertension, low HDL levels, or hypertriglyceridemia.  In the United States, nearly 50 million people have metabolic syndrome, for an age-adjusted prevalence of almost 24%. Of people with metabolic syndrome, more than 83% meet the criterion of obesity. Patients with metabolic syndrome have a higher risk for cardiovascular disease and are at increased risk for all-cause mortality.

Obstructive sleep apnea (OSA) is a condition characterized by recurrent episodes of upper airway obstruction occurring during sleep. Obesity is the greatest risk factor for OSA, and about 70% of patients (up to 80% of males and 50% of females) with OSA are obese.  OSA is defined as complete blockage of airflow during breathing lasting 10 seconds or longer, despite maintenance of neuromuscular ventilatory effort, and occurring five or more times per hour of sleep (Apnea Hypopnea Index, or AHI, greater than or equal to five), and accompanied by a decrease of at least 4% in arterial oxygen saturation.  This diagnosis can be made only in patients who undergo a sleep study. Obstructive sleep apnea is classified as mild, moderate, or severe, as follows:

  • Mild OSA =A HI of 5 to 15 events per hour
  • Moderate OSA = AHI of 15 to 30 events per hour
  • Severe OSA = AHI of more than 30 events per hour

Treatment is recommended for patients with moderate or severe disease, and initial treatment is the wearing of a continuous positive airway pressure (CPAP) device during sleep.

ANESTHETIC CHALLENGES

Every anesthesia task can be more difficult to perform in an obese patient.  Excess adipose tissue (fat) on the upper extremities makes it harder to place an IV catheter.  Excess fat surrounding the mouth, throat, and neck can make it more difficult to place an airway tube.  Excess fat can make it more difficult to place a needle in the proper position for a spinal anesthetic, an epidural anesthetic, or a regional block of a specific peripheral nerve.  On thick, cone-shaped upper arms, it can be difficult for a blood pressure cuff to detect the blood pressure accurately.

During surgery, an anesthesiologist’s job is to maintain the patient’s A-B-C’s of Airway, Breathing, and Circulation, in that order.  All three tasks are more difficult in obese patients.

Airway procedures are often much more difficult to perform in obese patients than in patients with normal BMIs.  Every general anesthetic begins with the anesthesiologist injecting intravenous medications that induce sleep.  Next the anesthesiologist controls the breathing by using a mask over the patient’s face, and then he or she places an airway tube through the patient’s mouth into the windpipe.

The airway anatomy of obese patients, with or without OSA, may show a short, thick neck, large tongue, and significantly increased amounts of soft tissue surrounding the uvula, tonsils, tongue, and lateral aspects of their throats.  This can contribute to the development of airway obstruction and also increase the probability that it will be more difficult to keep the airway open during mask ventilation.  This can also contribute to difficulty placing an anesthesia airway tube into the windpipe at the beginning of general anesthesia.

What about breathing difficulties?  The chief reason that obese patients have difficulty with breathing during anesthesia is that they have abnormally low lung volumes for their size.  When lying flat on their back, a patient’s increased abdominal bulk pushes up on their lungs, and prevents the lungs from inflating fully.  Once the patient is anesthetized, this mechanical situation is worsened, because breathing is impaired by the anesthetic drugs and muscle relaxation allows the abdomen to sink further into the chest.  The essence of the problem is that the abdomen squashes the lungs and makes them less efficient both as a reservoir and as an exchange organ for oxygen.  Because of this, the obese patient is at risk for running out of oxygen and turning blue more quickly than a lean patient.

In one study,  patients undergoing general anesthesia received 100% oxygen by facemask before induction of general anesthesia. After the induction of general anesthesia, the patients were left without ventilation until their oxygen saturation fell from 100% to 90%.  Patients with normal BMIs took 6 minutes for their oxygen level to fall to 90%. Obese patients reached that end point in less than 3 minutes.

What about circulation?  Maintaining stable circulatory status can be difficult because obese patients have a higher prevalence of cardiovascular disease, including hypertension, arrhythmias, stroke, heart failure, and coronary artery disease. During anesthesia and surgery, unexpected high or low blood pressure events are more common in obese patients than in those with normal BMIs.  Morbidly obese patients have a higher rate of heart attack postoperatively than patients with normal BMIs.

Regional anesthesia, especially epidural and spinal anesthesia, is often a safer technique than general anesthesia in obese patients. However, regional anesthesia can be  technically more difficult because of the physical challenge of the anatomy being obscured by excess fat.

Operative times are often longer in obese patients, owing to technical challenges for the surgeon regarding anatomy distorted or hidden behind excessive fat.  Longer surgery means a longer time under general anesthesia, which is a cause of delayed awakening from anesthesia. At the conclusion of surgery, obese patients wake more slowly than lean patients. Anesthetic drug and gas concentrations drop more slowly post-surgery, because traces of the chemicals linger in the reservoirs of excessive adipose tissue.

Common serious postoperative complications in obese patients include blood clots in the legs (deep venous thrombosis) and wound infections at the surgical incision line.

(Reference for this section:  Miller’s Anesthesia, 7th Edition, 2009, Chapter 64).

DATA ON THE RISKS OF OBESITY AND SURGERY

In one landmark study, researchers analyzed postoperative complications in 6,773 patients treated between 2001 and 2005 at the University of Michigan. Of the patients who had complications, 33% were obese and 15% were morbidly obese. Obese patients had much higher rates of postoperative complications than nonobese patients, as follows:  5 times more heart attacks, 4 times more peripheral nerve injuries, 1.7 times more  wound infections, and 1.5 times more urinary tract infections. The overall death rate was no different for obese and nonobese patients, but the death rate was nearly twice as high among morbidly obese patients as compared with nonobese patients (2.2% vs. 1.2%).

CONCLUSIONS

Experienced anesthesiologists respect the risks and difficulties presented by obese, morbidly obese, and super obese patients.  The ranks of overweight Americans are growing, and every week we anesthetize thousands of them for surgery.  As an obese American, are you safe in the operating room?  You probably are, because anesthesia professionals are well-educated in the risks of taking care of you. But you must realize that you are at higher risk for a complication than those with a normal BMI.

What can you do about all this? If you are morbidly obese and your surgery is optional, you may consider not having surgery at all.  If you have time before surgery, you can try to lose weight.  Before any surgery, you should consult your primary care physician to make sure that any obesity-related medical problems have been addressed.  You may be placed on medication for hypertension, hyperlipidemia, or diabetes.  You may have undiagnosed OSA, and may benefit from a nightly CPAP treatment for that disorder.

Bariatric surgery (e.g., gastric banding, gastric bypass) is a well-accepted and effective treatment for weight loss in super obese and morbidly obese patients.  Bariatric surgery refers to surgical alteration of the small intestine or stomach with the aim of producing weight loss. More than 175,000 bariatric surgeries were performed in 2006, and more than 200,000 were performed in 2008 (Miller’s Anesthesia, 7th Edition, 2009, Chapter 64). Weight loss after bariatric surgery is often dramatic. On the average, patients lose 60% of their extra weight. For example, a 350-pound person who is 200 pounds overweight could lose about 120 pounds.  All the anesthetic considerations and risks discussed above would still apply to any patient coming to the operating room for weight loss surgery.

Obesity was considered a rarity until the middle of the 20th century.  Now more than 300,000 deaths per year in the United States and more than $100 billion in annual health care spending are attributable to obesity. Obesity most frequently develops when food calorie intake exceeds energy expenditure over a long period of time.

If you’re obese, this doctor recommends you eat less, and exercise more.  Stay lean if you can.  Your anesthesiologist will thank you.

THE TOP TEN MOST USEFUL ADVANCES AND THE FIVE MOST OVERRATED ADVANCES AFFECTING ANESTHESIA IN THE PAST 25 YEARS

THE ANESTHESIA CONSULTANT

In 1986 the American Society of Anesthesiologists adopted pulse oximetry and end-tidal CO2 monitoring as standards of care.  These two monitors were our specialty’s major advances in the 1980’s, and made anesthesia safer for everyone. What are the most significant advances affecting anesthesia since that time? As a clinician in private practice, I’ve personally administered over 20,000 anesthetics in the past quarter century.  Based on my experience and observations, I’ve assembled my list of the Top Ten Most Useful Advances Affecting Anesthesia from 1987-2012.  I’ve also assembled my list of the Five Most Overrated Advances Affecting Anesthesia from 1987-2012.

THE TOP TEN MOST USEFUL ADVANCES AFFFECTING ANESTHESIA IN THE PAST 25 YEARS (1987- 2012):

#10. The cell phone (replacing the beeper).  Cell phones changed the world, and they changed anesthesia practice as well.  Before the cell phone, you’d get paged while driving home and have to search to find a payphone.  Cell phones allow you to be in constant contact with all the nurses and doctors involved in your patient’s care at all times.  No one should carry a beeper anymore.

#9. Ultrasound use in the operating room.  The ultrasound machine aids peripheral nerve blockade and catheter placement, and intravascular catheterization.  Nerve block procedures used to resemble “voodoo medicine,” as physicians stuck sharp needles into tissues in search of paresthesias and nerve stimulation.  Now we can see what we’re doing.

#8.  The video laryngoscope.  Surgeons have been using video cameras for decades.  We finally caught up.  Although there’s no need for a video laryngoscope on routine cases, the device is an invaluable tool for seeing around corners during difficult intubations.

#7.  Rocuronium.  Anesthesiologists long coveted a replacement for the side-effect-ridden depolarizing muscle relaxant succinylcholine.  Rocuronium is not as rapid in onset as succinylcholine, but it is the fastest non-depolarizer in our pharmaceutical drawer.  If you survey charts of private practice anesthesiologists, you’ll see rocuronium used 10:1 over any other relaxant.

#6.  Zofran.  The introduction of ondansetron and the 5-HT3 receptor blocking drugs gave anesthesiologists our first effective therapy to combat post-operative nausea and vomiting.

#5. The ASA Difficult Airway Algorithm.  Anesthesia and critical care medicine revolve around the mantra of “Airway-Breathing-Circulation.”  When the ASA published the Difficult Airway Algorithm in Anesthesiology in 1991, they validated a systematic approach to airway management and to the rescue of failed airway situations.  It’s an algorithm that we’ve all committed to memory, and anesthesia practice is safer as a result.

#4.  The internet.  The internet changed the world, and the Internet changed anesthesia practice as well.  With Internet access, clinicians are connected to all known published medical knowledge at all times.  Doctors have terrific memories, but no one remembers everything.  Now you can research any medical topic in seconds. Some academics opine that the use of electronic devices in the operating room is dangerous, akin to texting while driving.  Monitoring an anesthetized patient is significantly different to driving a car.  Much of O.R. monitoring is auditory.  We listen to the oximeter beep constantly, which confirms that our patient is well oxygenated.  A cacophony of alarms sound whenever vital signs vary from norms.  An anesthesia professional should never let any electronic device distract him or her from vigilant monitoring of the patient.

#3.  Sevoflurane.  Sevo is the volatile anesthetic of choice in community private practice, and is a remarkable improvement over its predecessors.  Sevoflurane is as insoluble as nitrous oxide, and its effect dissipates significantly faster than isoflurane.  Sevo has a pleasant smell, and it replaced halothane for mask inductions.

#2.  Propofol.  Propofol is wonderful hypnotic for induction and maintenance.   It produces a much faster wake-up than thiopental, and causes no nausea.  Propofol makes us all look good when recovery rooms are full of wide-awake, happy patients.

#1.  The Laryngeal Mask Airway.  What an advance the LMA was.  We used to insert endotracheal tubes for almost every general anesthesia case.  Endotracheal tubes necessitated laryngoscopy, muscle relaxation, and reversal of muscle relaxation.  LMA’s are now used for most extremity surgeries, many head and neck surgeries, and most ambulatory anesthetics.

THE FIVE MOST OVERRATED ADVANCES AFFECTING ANESTHESIA IN THE PAST 25 YEARS (1987-2012):

#5.   Office-based general anesthesia.  With the advent of propofol, every surgeon with a spare closet in their office became interested in doing surgery in that closet, and they want you to give general anesthesia there.  You can refuse, but if there is money to be earned, chances are some anesthesia colleague will step forward with their service.  Keeping office general anesthesia safe and at the standard of care takes careful planning regarding equipment, monitors, and emergency resuscitation protocols.  Another disadvantage is the lateral spread of staffing required when an anesthesia group is forced to cover solitary cases in multiple surgical offices at 7:30 a.m.  A high percentage of these remote sites will have no surgery after 11 a.m.

#4.  Remifentanil.  Remi was touted as the ultra-short-acting narcotic that paralleled the ultra-short hypnotic propofol.  The problem is that anesthesiologists want hypnotics to wear off fast, but are less interested in narcotics that wear off and don’t provide post-operative analgesia.  I see remi as a solid option for neuroanesthesia, but its usefulness in routine anesthetic cases is minimal.

#3.  Desflurane.  Desflurane suffers from not being as versatile a drug as sevoflurane.  It’s useless for mask inductions, causes airway irritation in spontaneously breathing patients, and causes tachycardia in high doses.  Stick with sevo.

#2.  The BIS Monitor.  Data never confirmed the value of this device to anesthesiologists, and it never gained popularity as a standard for avoiding awareness during surgery.

#1.  The electronic medical record.  Every facet of American society uses computers to manage information, so it was inevitable that medicine would follow. Federal law is mandating the adoption of EMRs.  But while you are clicking and clicking through hundreds of Epic EMR screens at Stanford just to finish one case, anesthesiologists in surgery centers just miles away are still documenting their medical records in minimal time by filling out 2 or 3 sheets of paper per case. Today’s EMRs are primitive renditions of what will follow. I’ve heard the price tag for the current EMR at our medical center approached $500 million.  How long will it take to recoup that magnitude of investment?  I know the EMR has never assisted me in caring for a patient’s Airway, Breathing, or Circulation in an acute care setting.  Managing difficulties with the EMR can easily distract from clinical care.  Is there any data that demonstrates an EMR’s value to anesthesiologists or perioperative physicians?

Your Top Ten List and Overrated Five List will differ from mine.  Feel free to communicate your opinions to me at rjnov@yahoo.com.

As we read this, hundreds of companies and individuals are working on new products.  Future Top Ten lists will boast a fresh generation of inventions to aid us in taking better care of our patients.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

AWARENESS UNDER GENERAL ANESTHESIA

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

How common is awareness under general anesthesia? In 2007, Hollywood released the movie Awake, in which the protagonist, played by Hayden Christensen (Anakin Skywalker from Star Wars) is awake during the general anesthetic for his heart surgery, and overhears the surgeon’s plan to murder him.  Producer Joana Vicente told Variety that Awake “will do to surgery what Jaws did to swimming in the ocean.” The movie trailer airs a statement that states, “Every year 21 million people are put under anesthesia. One out of 700 remain awake.”

 

            Awake was not much of a commercial success, with a total box office of only $32 million, but the film did publicize the issue of intraoperative awareness under general anesthesia, a topic worth reviewing.

If you undergo general anesthesia, do you have a 1 in 700 chance of being awake?  If you are a healthy patient undergoing routine surgery, the answer is no.  If you are sick and you are having a high-risk procedure, the answer is yes.

A key publication on this topic was the Sebel study. The Sebel study was a prospective, nonrandomized study, conducted on 20,000 patients at seven academic medical centers in the United States. Patients were scheduled for surgery under general anesthesia, and then interviewed in the postoperative recovery room and at least one week after anesthesia.

A total of 25 awareness cases were identified, a 0.13% incidence, which approximates the 1 in 700 incidence quoted in the Awake movie trailer. Awareness was associated with increased American Society of Anesthesiologists (ASA) physical status, i.e. sicker patients.  Assuming that approximately 20 million anesthetics are administered in the United States annually, the authors postulated that approximately 26,000 cases of intraoperative awareness occur each year.

Healthy patients are at minimal risk for intraoperative awareness. Patients at higher risk for intraoperative awareness include:

1. Patients with a history of substance abuse or chronic pain.

2. American Society of Anesthesiologists (ASA) Class 4 patients (patients with a severe systemic disease that is a constant threat to their life) and others with limited cardiovascular reserve.

3. Patients with previous history of intraoperative awareness.

4. The use of neuromuscular paralyzing drugs during the anesthetic.

5. Certain surgical procedures are higher risk for intraoperative awareness.  These procedures include cardiac surgery, Cesarean sections under general anesthesia, trauma or emergency cases.

The causes of intraoperative awareness include:

1. Intentionally light anesthesia administered to patients who are hypotensive or hypovolemic, or those with limited cardiovascuar reserve.

2. Intentionally light anesthesia administered to obstetric patients, in the attempt to avoid neonatal respiratory depression.

3. Efforts to expedite operating room turnover and minimize recovery room times.

4. Some patients have higher anesthetic requirements, due to chronic alcohol or drugs.

5. Equipment and provider errors:

Empty vaporizers with no potent anesthetic liquid inside

Syringe pump malfunction

Syringe swap, or mislabeling of a syringe

6. Difficult intubation, in which the anesthesia provider forgets to give supplementary IV doses of hypnotics.

7. Choice of anesthetic.  In multiple trials, the use of neuromuscular blockers is associated with awareness.

8. Some studies show a higher incidence of awareness with total intravenous anesthesia or nitrous-narcotic techniques.

What are the legal implications of intraoperative awareness?

The Domino study reported that cases of awareness represented 1.9% of malpractice claims against anesthesiologists. Deficiencies in labeling syringes and vigilance were common causes for awake paralysis. The patients’ vital signs were not classic clues:  hypertension was present in only 15% of recall cases, and tachycardia was present in only 7%.

What are the consequences of intraoperative awareness?

The following consequences have been reported from the Samuelsson study:

1. Recollections of auditory perceptions and a sensation of paralysis.  Anxiety, helplessness, and panic.  Pain is described less frequently.

2. Up to 70% of patients develop Post-Traumatic Stress Disorder (PTSD), i.e. late psychological symptoms of anxiety, panic attacks, chronic fear, nightmares, flashbacks, insomnia, depression, or preoccupation with death.

What about BIS Monitoring?

Bispectral Index monitoring, or BIS monitoring, uses a computerized algorithm to convert a single channel of frontal EEG into an index score of hypnotic level, ranging from 100 (awake) to 0 (isoelectric EEG).

The BIS monitor was FDA-approved in 1996.  A BIS level of 40 – 60 reflects a low probability of consciousness during general anesthesia.  BIS measures the hypnotic components of anesthesia (e.g. effects of propofol and volatile agents), and is relatively insensitive to analgesic components (e.g. narcotics) of the anesthetic.  The BIS monitor is neither 100% sensitive nor 100% specific.

The B-Aware Trial was a randomized, double-blind, multi-center controlled trial using BIS in 2500 patients at high risk for awareness (cardiac surgery, C-sections, impaired cardiovascular status, trauma, chronic narcotic users, heavy alcohol users).   Explicit recall occurred in 0.16% (2 patients) when BIS used, vs. 0.89% (11 patients) when no BIS was used. This was a significant finding (p=0.022).

A significant paper published in the world’s leading anesthesia journal concluded that the predictive positive and negative values of BIS monitoring were low due to the infrequent occurrence of intraoperative awareness.  In addition, the cost of BIS monitoring all patients undergoing general anesthesia is high. Because there have been reported cases of awareness despite BIS monitoring, the authors concluded that the effectiveness of the monitor is less than 100%. The authors concluded that the contention that BIS Index monitoring reduces the risk of awareness is unproven, and the cost of using it for this indication is currently unknown.

In 2005, the American Society of Anesthesiologists published its Practice Advisory for Intraoperative Awareness.  The anesthesia practitioner is advised to do the following:

1. Review patient medical records for potential risk factors. (Substance use or abuse, previous history of intraoperative awareness, history of difficult intubation, chronic pain patients using high doses of opioids, ASA physical status IV or V, limited hemodynamic reserve).

2. Determine other potential risk factors. (Cardiac surgery, C-section, trauma surgery, emergency surgery, reduced anesthetic doses in the presence of paralysis, planned use of muscle relaxants during the maintenance phase of general anesthesia, planned use of nitrous oxide-opioid anesthesia).

3. Patients considered to be at increased risk of intraoperative awareness should be informed of the possibility when circumstances permit.

4. Preinduction checklist protocol for anesthesia machines and equipment to assure that the desired anesthetic drugs and doses will be delivered.  Verify IV access, infusion pumps, and their connections.

5. The decision to administer a benzodiazepine prophylactically should be made on a case-by-case basis for selected patients.

6. Intraoperative monitoring of depth of anesthesia, for the purpose of minimizing the occurrence of awareness, should rely on multiple modalities, including clinical techniques (e.g., ECG, blood pressure, HR, end-tidal anesthetic gas analyzer, and capnography)…. Brain function monitoring is not routinely indicated for patients undergoing general anesthesia, either to reduce the frequency of intraoperative awareness or to monitor depth of anesthesia…. The decision to use a brain function monitor should be made on a case-by-case basis by the individual practitioner of selected patients (e.g. light anesthesia).

Published suggestions for the prevention of awareness include:

1. Premedication with an amnestic agent.

2. Giving adequate doses of induction agents.

3. Avoiding muscle paralysis unless totally necessary.

4. Supplementing nitrous/narcotic anesthesia with 0.6% MAC of a volatile agent.

5. Administering 0.8 – 1.0 MAC when volatile agent is used alone.

6. Confirming delivery of anesthetic agents to the patient

In 2006, the California Society of Anesthesiologists released the following Statement on Intraoperative Awareness:

“ . . . Anesthesiologists are trained to minimize the occurrence of awareness under general anesthesia.  It is recognized that on rare occasions, usually associated with a patient’s critical condition, this may be unavoidable.  Furthermore, it is commonplace in contemporary anesthetic practice to employ a variety of techniques using regional nerve blocks and varying degrees of sedation.  Patients often do not make an distinction between these techniques and general anesthesia, yet awareness is often expected and anticipated with the former.  This may have led to a misunderstanding of ‘awareness’ during surgery by many patients.”

In 2011, the New England Journal of Medicine, arguably the most prestigious medical journal in the world, published a study looking at using the BIS monitor for the prevention of intraoperative awareness. Prevention of intraoperative awareness in a high-risk surgical population). The researchers tested the hypothesis that a protocol incorporating the electroencephalogram-derived bispectral index (BIS) was superior to a protocol incorporating standard monitoring of end-tidal anesthetic-agent concentration (ETAC) for the prevention of awareness. They randomly assigned 6041 patients at high risk for awareness to either BIS-guided anesthesia or ETAC-guided anesthesia. Results showed that a total of 7 of 2861 patients (0.24%) in the BIS group, as compared with 2 of 2852 (0.07%) in the ETAC group, had definite intraoperative awareness.  The superiority of the BIS protocol was not established.  Contrary to expectations, fewer patients in the ETAC group than in the BIS group experienced awareness.

To conclude, intraoperative awareness is a real but rare occurrence, with certain patient populations at higher risk. The BIS monitor is no panacea. Specific pharmacologic strategies can minimize the incidence of awareness. If you are a healthy patient undergoing a routine procedure, intraoperative awareness should be very rare.

The best defense against intraoperative awareness will always be the presence of a well-trained and vigilant physician anesthesiologist.

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too. Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?” The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

ROBOT ANESTHESIA

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Will robots replace anesthesiologists? I am the Medical Director of a surgery center in California that does 5,000 gastroenterology endoscopies per year.  In 2013 a national marketing firm contacted me to seek my opinion regarding an automated device to infuse propofol. The device was envisioned as a tool for gastroenterologist/nursing teams to use to administer propofol safely for endoscopy procedures on ASA class I – II patients.

The marketing firm could not reveal the name of the device, but I believe it was probably the SEDASYS®-Computer-Assisted Personalized Sedation System, developed by the Ethicon Endo-Surgery, Inc., a division of Johnson and Johnson.  The SEDASYS System is a computer-assisted personalized sedation system integrating propofol delivery with patient monitoring. The system incorporates standard ASA monitors, including end-tidal CO2, into an automated propofol infusion device.

The SEDASYS system is marketed as a device to provide conscious sedation.  It will not provide deep sedation or general anesthesia.

Based on pharmacokinetic algorithms, the SEDASYS infuses an initial dose of propofol (typically 30- 50 mg in young patients, or a smaller dose in older patients) over 3 minutes, and then begins a maintenance infusion of propofol at a pre-programmed rate (usually 50 mcg/kg/min).  If the monitors detect signs of over- sedation, e.g. falling oxygen saturation, depressed respiratory rate, or a failure of the end-tidal CO2 curve, the propofol infusion is stopped automatically.  In addition, the machine talks to the patient, and at intervals asks the patient to squeeze a hand-held gripper device.  If the patient is non-responsive and does not squeeze, the propofol infusion is automatically stopped.

As of February, 2013, the SEDASYS system was not FDA approved. On May 3, 2013, Ethicon Endo-Surgery, Inc. announced that the Food and Drug Administration (FDA) granted Premarket Approval for the SEDASYS® system, a computer-assisted personalized sedation system.  SEDASYS® is indicated “for the intravenous administration of 1 percent (10 milligrams/milliliters) propofol injectable emulsion for the initiation and maintenance of minimal to moderate sedation, as identified by the American Society of Anesthesiologists Continuum of Depth of Sedation, in adult patients (American Society of Anesthesiologists physical status I or II) undergoing colonoscopy and esophagoduodenoscopy procedures.”  News reports indicate that SEDASYS® is expected to be introduced on a limited basis beginning in 2014.

Steve Shaffer, M.D., Ph.D., Stanford Adjunct Professor, editor-in-chief of Anesthesia & Analgesia, and Professor of Anesthesiology at Columbia University, worked with Ethicon since 2003 on the design, development and testing of the SEDASYS System both as an investigator and as chair of the company’s anesthesia advisory panel.

Dr. Shafer has been quoted as saying, “The SEDASYS provides an opportunity for anesthesiologists to set up ultra-high throughput gastrointestinal endoscopy services, improve patient safety, patient satisfaction, endoscopist satisfaction and reduce the cost per procedure.” (Gastroenterology and Endoscopy News, November 2010, 61:11)

In Ethicon’s pivotal study supporting SEDASYS, 1,000 ASA class I to III adults had routine colonoscopy or esophagogastroduodenoscopy, and were randomized to either sedation with the SEDASYS System (SED) or sedation with each site’s current standard of care (CSC) i.e. benzodiazepine/opioid combination.  The reference for this study is Gastrointest Endosc. 2011 Apr;73(4):765-72. Computer-assisted personalized sedation for upper endoscopy and colonoscopy: a comparative, multicenter randomized study. Pambianco DJ, Vargo JJ, Pruitt RE, Hardi R, Martin JF.

In this study, 496 patients were randomized to SED and 504 were randomized to CSC. The area under the curve of oxygen desaturation was significantly lower for SED (23.6 s·%) than for CSC (88.0 s·%; P = .028), providing evidence that SEDASYS provided less over-sedation than current standard of care with benzodiazepine/opioid.  SEDASYS patients were significantly more satisfied than CSC patients (P = .007). Clinician satisfaction was greater with SED than with CSC (P < .001). SED patients recovered faster than CSC patients (P < .001). The incidence of adverse events was 5.8% in the SED group and 8.7% in the CSC group.

Donald E. Martin, MD, associate dean for administration at Pennsylvania State Hershey College of Medicine and chair of the Section on Clinical Care at the American Society of Anesthesiologists (ASA), expressed concerns about the safety of the device.  Dr. Martin (Gastroenterology and Endoscopy News, November 2010, 61:11) was quoted as saying, “SEDASYS is requested to provide minimal to moderate sedation and yet the device is designed to administer propofol in doses known to produce general anesthesia.”

Dr. Martin added that studies to date have shown that some patients who had  propofol administered by SEDASYS experienced unconsciousness or respiratory depression (Digestion 2010;82:127-129, Maurer WG, Philip BK.). In the largest prospective, randomized trial evaluating the safety of the device compared with the current standard of care, five patients (1%) experienced general anesthesia with SEDASYS. The ASA also voiced concern that SEDASYS could be used in conditions that do not comply with the black box warning in the propofol label, namely that propofol “should be administered only by persons trained in the administration of general anesthesia and not involved in the conduct of the surgical/diagnostic procedure.”

Anesthetists, emergency room doctors, and trauma helicopter nurses are trained in the administration of general anesthesia. Gastroenterologists and endoscopy nurses are almost never experts in airway management.  For this reason, propofol anesthetics for endoscopy are currently the domain of anesthesiologists and nurse anesthetists.

In my phone conversation regarding the automated propofol-infusion system, I told the marketing company’s representative that in my opinion a machine that infused propofol without an airway expert present could be unsafe.  The marketing consultant responded that in parts of the Northeastern United States, including New York City, many GI endoscopies are done with the assistance of an anesthesia provider administering propofol.  If SEDASYS were to be approved, the devices could replace anesthesiologists.

In the current fee-for-service model of anesthesia billing, anesthesiologists and CRNA’s bill insurance companies or Medicare for their professional time.  If machines replace anesthesiologists and CRNA’s, the anesthesia team cannot send a fee-for-service bill for professional time.  The marketing consultant foresaw that with the advent of ObamaCare and Accountable Care Organizations, if a health care organization is paid a global fee to take care of a population rather than being paid a fee-for-service sum, then perhaps the cheapest way to administer propofol sedation for GI endoscopy would be to replace anesthesia providers with SEDASYS machines.

A planned strategy is to have gastroenterologists complete an educational course that would educate them on several issues.  Key elements of the course would be: 1) anesthesiologists are required if deep sedation is required, 2) SEDASYS is not appropriate if the patient is ASA 3 or 4 or has severe medical problems, 3) SEDASYS is not appropriate if the patient has risk factors such as morbid obesity, difficult airway, or sleep apnea, and 4) airway skills are to be taught in the simulation portion of the training.  Specific skills are chin life, jaw thrust, oral airway use, nasal airway use, and bag-mask ventilation.  Endotracheal intubation and LMA insertion are not to be part of the class.  If the endoscopist cannot complete the procedure with moderate sedation, the procedure is to be cancelled and rescheduled with an anesthesia provider giving deep IV sedation.

Some anesthesiologists are concerned about being pushed out of their jobs by nurse anesthetists.  It may be that some anesthesiologists will be pushed out of their jobs by machines.

I’ve been told that the marketing plan for SEDASYS is for the manufacturer to give the machine to a busy medical facility, and to only charge for the disposable items needed for each case. The disposable items would cost $50 per case. In our surgery center, where we do 5,000 cases per year, this would be an added cost of $25,000 per year. There would be no significant savings, because we do not use anesthesiologists for most gastroenterology sedation.

There have been other forays into robotic anesthesia, including:

1) The Kepler Intubation System (KIS) intubating robot, designed to utilized video laryngoscopy and a robotic arm to place an endotracheal tube (Curr Opin Anaesthesiol. 2012 Oct 25. Robotic anesthesia: not the realm of science fiction any more. Hemmerling TM, Terrasini N. Departments of Anesthesia, McGill University),

2) The McSleepy intravenous sedation machine, designed to administer propofol, narcotic, and muscle relaxant to patients to control hypnosis, analgesia, and muscle relaxation. (Curr Opin Anaesthesiol. 2012 Dec;25(6):736-42. Robotic anesthesia: not the realm of science fiction any more. Hemmerling TM, Terrasini N.)

3) The use of the DaVinci surgical robot to perform regional anesthetic blockade. (Anesth Analg. 2010 Sep;111(3):813-6. Epub 2010 Jun 25. Technical communication: robot-assisted regional anesthesia: a simulated demonstration. Tighe PJ, Badiyan SJ, Luria I, Boezaart AP, Parekattil S.).

4) The use of the Magellan robot to place peripheral nerve blocks (Anesthesiology News, 2012, 38:8)

Each of these applications may someday lead to the performance of anesthesia by an anesthesiologist at geographical distance from the patient.  In an era where 17% of the Gross National Product of the United States is already being spent on health care, one can question the logic of building expensive technology to perform routine tasks like I.V. sedation, endotracheal intubation, or regional block placement.  The new inventions are futuristic and interesting, but a DaVinci surgical robot costs $1.8 million, and who knows what any of these anesthesia robots would sell for?  The devices seem more inflationary than helpful at this point.

Will robots replace anesthesiologists?  Inventors are edging in that direction.  I would watch the peer-reviewed anesthesia journals for data that validates the utility and safety of any of these futuristic advances.

It will be a long time before anyone invents a machine or a robot that can perform mask ventilation.  SEDASYS is designed for conscious sedation, not deep sedation or general anesthesia.  Anyone or anything that administers general anesthesia without expertise in mask ventilation and all facets of airway management is courting disaster.

NOTE: In March of 2016, Johnson & Johnson announced that they were going to stop selling the SEDASYS system due to slow sales and company-wide cost cutting. The concept of Robot Anesthesia will have to wait for some future development, if ever, if it is to ever become an important part of the marketplace.

ANESTHESIOLOGISTS KNOW WHO THE BEST SURGEONS ARE

THE ANESTHESIA CONSULTANT

You’re a patient.  Is your surgeon a wonderful doctor, superb under pressure, or is he or she a self-absorbed nervous individual who can’t operate their way out of a paper bag? You don’t know.  Your anesthesiologist does. Anesthesiologists watch surgeons for a living.

 

Yes, we happen to give anesthetics to patients at the same time, but we anesthesiologists are always watching surgeons work.  If you want to know who the best surgeons are, ask an anesthesiologist, an operating room nurse, or an operating room scrub tech.  We see the surgeons on the front line, and we see their strengths and weaknesses.

Most surgeons spend the majority of their professional time in clinics, meeting patients in preoperative surgical consultations or in postoperative surgical follow up.  Most surgeons operate 1 – 2 days per week.  In contrast, most anesthesiologists have no clinic, and work 90-100% of their time in operating rooms.  In a typical week, an anesthesiologist may do 20-25 anesthetics with 10 – 15 different surgeons.  In a typical year, a busy anesthesiologist may work with 100 – 150 different surgeons.

In an operating room, the anesthesiologist stands 2 to 6 feet away from the surgeon, and has a clear view of the surgeon’s technique and an excellent opportunity to establish rapport with the surgical team.  Anesthesiologists and surgeons know each other very well.

As a patient, you may form your impressions of your surgeon based on encounters in the office or in your hospital room.  Favorable surgeons cast an air of confidence, intelligence, leadership and experience.  You may trust the look in their eye, the tenor of their voice, the firmness of their handshake.  You may like or dislike their necktie, their suit, their haircut or their bedside manner.

You have no idea how competent they are once they don sterile gown and gloves in the operating room, but anesthesiologists know.

The surgeon with the firm handshake may have hands that genuinely shake when they are in surgery.  The slick-appearing surgeon may operate in low gear, their fingers moving as slowly as a twig winding downstream in a muddy river.  In the operating room, the surgeon may be a benevolent professional or a moody tyrant who screams and swears at nurses and techs.  The surgeon with the killer smile may cling to outdated techniques or equipment.  Alternately, the surgeon may be world-class technician who knows his or her anatomy cold, handles tissue with exacting precision, and treats everyone on the surgical team like gold.

What can you, the patient, do about accessing information about your surgeon?

You can Google the surgeon’s name to seek information on their professional background, as well as any Yelp comments on other patient’s experiences with that doctor.  If you know anyone who works at that hospital or surgery center, it’s worth your while to query them and get their insider’s impression about the choice of surgeons that work there.  If you can talk to an anesthesiologist, operating room nurse, or operating scrub tech, they will be your best source of information as to which surgeon to consult.

Good luck.  All surgeons are different.  And remember: tonight when you are watching television, thousands of anesthesiologists are watching thousands of surgeons all over the United States.

BLINK: WHEN AN EXPERIENCED ANESTHESIOLOGIST MEETS THEIR PATIENT

THE ANESTHESIA CONSULTANT

I urge you to use Malcolm Gladwell’s book Blink to become a better anesthesiologist. Clinical Case for Discussion:  As an anesthesia resident, how does your preoperative interview with a patient differ from that of an anesthesiologist with 20 years of experience?

Discussion:  In my second year of residency, I had the pleasure of working with Stanford anesthesia attending C. Philip Larson, M.D., a Past-Chairman of the Department and a Past Editor-In-Chief of our specialty’s leading publication, Anesthesiology.  My rotation was neuroanesthesia, and each evening prior to surgery Dr. Larson and I would make rounds on the wards to meet the surgical patients for the next day. (In the 1980’s almost all patients were hospitalized one night prior to surgery.)

I was surprised and taken aback by the experience, and I never forgot what those patient encounters were like.  Although Dr. Larson always let me do the anesthesia procedures in the operating room, he presented himself at the pre-op interview as the primary physician in charge of the anesthesia care.  When Dr. Larson entered a patient’s room, he sat down on the bed and played a role that was part Santa Claus and part all-knowing, all-loving deity.

Dr. Larson greeted the patient kindly, introduced both of us, and then launched into a comfortable dialogue about any variety of topics, none of them remotely related to the surgery or the anesthesia.  I kept waiting to hear him say, “can you walk up two flights of stairs?” or “do you ever have chest pain?”

These questions were never asked or answered at the bedside.  They’d already been asked and answered and were present in the patient’s chart.  Dr. Larson valued the preoperative interview as a time to connect with his patient, and to establish rapport and comfort between them.  After perhaps ten minutes of such banter, he would switch gears and state that we would be doing the anesthesia care the next day, that we would keep him or her asleep and safe, and give a modicum of detail about what to expect.  He did not perform any detailed physical exam.

Despite the fact that Dr. Larson was a renowned expert witness in the specialty of anesthesia, he did not recite a litany of informed consent risks.  A particular pet peeve of his was the suggestion that an informed consent discussion should include telling a patient of the risk of death.  His opinion on this issue always was, “If you tell the patient that they can die, and then you do something negligent and they do die, your informed consent protects you not one bit from the fact that you practiced below the standard of care.”

In his best-selling book, Blink, Malcolm Gladwell writes that the risk of a doctor ever being sued has very little to do with how many errors they make.  He explains that there’s an overwhelming number of patients who’ve been harmed by shoddy medical care yet never have filed a malpractice claim.  What was the common denominator of the people who do choose to sue?  According to Gladwell, they feel they were treated badly by their doctor.  That even when injured by clear negligence, most people won’t sue a doctor they like.

Dr. Bruce Halperin, a member of the Associated Anesthesiologists Medical Group in Palo Alto and a member of the Stanford clinical faculty, was renowned for his bedside manner.  In the preoperative area, I often heard Dr. Halperin telling joke after joke, and the intermittent bursts of laughter from his patients sometimes made it difficult for me to even hear the conversation with my own patient.  One of our busiest cosmetic surgeons often had Dr. Halperin telephone patients early in the consultative process to discuss anesthesia issues.  A patient later told this surgeon, “I’m not sure if I want to have the plastic surgery, but I sure do want to have the anesthesia!”

As an anesthesiologist, you have 10-15 minutes to complete your medical interview with your patient, and to get them to respect you, to have confidence in you, and yes . . . to like you.

As a resident-in-training, your preoperative interviews may be thick with questions about active medical problems, particularly cardiac, pulmonary, and neurologic questions.  You may perform a rigorous and detailed exam of the airway, lungs, and heart.  And you likely spend ample time explaining the anesthetic technique, alternatives, and risks.

You are trained to do all these things.  Twenty years from now, your interview may not be as conversational and sparse on medical questions as Dr. Larson’s was, but your technique will evolve.

Most pertinent questions have already been asked and answered in the patient’s medical records.  Tailor your interview as appropriate for the patient’s medical co-morbidities and the invasiveness of the surgery.  For a 68-year-old with diabetes and hypertension who is about to have a cholecystectomy, it will be relevant to ask them whether they can walk up two flights of stairs and whether they ever have chest pain.  For a 24-year-old with a negative history who is about to have a knee arthroscopy, a simple “Are you in excellent health?” may suffice.

What about the physical exam?  For experienced anesthesiologists, the assessment of whether the airway may be difficult can usually accomplished in seconds, with examination of the mouth opening and the neck extension.  You will listen to the lungs and the heart, but in the absence of symptoms, it is rare to uncover any information with your stethoscope that changes your anesthetic.

Patients are nervous before surgery.  They welcome both your expertise in medicine and your skills in making them relax.  Experienced anesthesiologists can explain the anesthetic plan and risks in a fashion that will gain the patient’s trust and confidence.

The only procedure most of us do while the patient is awake and unsedated is the insertion of an I.V. catheter.  This is a time when you have the luxury of talking about any topic that is calming to the patient.  Conversations about the patient’s hobbies, work, hometown, or family are all pleasant diversions to enter the realm of Dr. C. Philip Larson, and connect with the patient without talking any further about anesthesia.

In my previous career, I was an internal medicine doctor.  In medicine clinic there are dozens of questions to be asked and answered:  “Where is the pain?  How long has it been there?  What makes it better?  What makes it worse?  Does it move anywhere? . . .”  With a waiting room full of patients, there was little time to ask each patient where they had dinner last night or where their child was going to college.

In contrast, anesthesia practice can provide a wonderful opportunity to relax your patient with well-spun conversation.  My advice to you is to be as much like C. Philip Larson, M.D. as your practice allows.  Try not to be a walking, talking EPIC-checklist when it’s time to connect with your patients.

THE ANESTHESIA CONSULTANT

When you have surgery, do you care who administers your anesthetic? You should. An oft-repeated medical adage states:“anesthesia is 99% boredom and 1% panic.

36164768-a-depiction-of-the-pearly-gates-of-heaven-open-with-the-bright-side-of-heaven-contrasting-with-the-d

GOALIES AT THE PEARLY GATES

As an anesthesiologist who’s delivered over 50,000 hours of operating room care over 25 years, I can attest that the adage is true.  Ninety-nine percent of the time, the anesthesia provider’s job requires vigilance during a patient’s stable progression of metronome heartbeats and regular breathing, but 1% of the time requires clear thinking and prompt action during moments of sheer panic. These stress-filled episodes of panic are unknown to the general public, yet represent ordeals that every anesthesia provider must rise above to protect their patients.

Webster’s Dictionary defines panic as “ an overwhelming feeling of fear and anxiety.”  If you were to observe an anesthesiologist at work, you would see little or no evidence of overwhelming fear or anxiety.  Even under dire emergencies, most anesthesia providers remain outwardly composed and efficient while they make the necessary diagnoses and apply the appropriate treatments.  But anesthesiologists are human–no human can watch another human trying to die without feeling intense emotions.  These emotions are fear and anxiety.

No field of medicine provides the stunning variety of anesthesia.  Patients vary from neonates to centenarians, from laboring women to motor vehicle accident victims at three a.m., while surgeries vary from repair of a broken finger to the transplantation of a heart or a liver.  Technologic advances have led surgeons to operate on older and sicker patients, and to attempt more complex surgeries than decades ago.

The operating room is an intense environment.  Operating room medicine is pressure-packed for four reasons:

  1. Anesthetic drugs change the physiology of patients in profound ways.
  2. Surgeons do dangerous things to patients.
  3. Surgical patients have diseases.  Some of these diseases are urgent or severe.
  4. Human beings make errors.  This includes both surgeons and anesthesia providers.

Unbelievable events occur at unexpected times in operating rooms, and your anesthesia provider must keep you safe.  He or she is in control of your airway, breathing, and circulation at every moment.  Your anesthesia provider is your insurance policy against medical complications during surgery.  Your anesthesia provider’s job is to play Goalie at the Pearly Gates, and keep you alive.

The individual administering your anesthesia can vary–your anesthesia provider may be:

  1. a medical doctor (an anesthesiologist),
  2. a certified registered nurse anesthetist (CRNA) or anesthesia assistant (AA) supervised by an anesthesiologist, or
  3. a CRNA working without anesthesiologist supervision.

In the United States, anesthesiologists personally administer 35% of the anesthetics.  Anesthesia care teams, in which an anesthesiologist medically directs a team of AA’s or CRNA’s, administer 55% of the anesthetics.  CRNA’s, working unsupervised, administer 10% of the anesthetics.

There are people who perceive anesthesia care to be so safe that it can be taken for granted.  They are wrong.  Anesthesia care is safest when a physician, a board-certified anesthesiologist, directs the anesthetic care.  Published data shows that:

  1. Mortality rates after surgery are significantly lower when anesthesiologists direct anesthesia care.
  2. Failure-to-rescue rates (the rate of death after a complication) are significantly lower when anesthesiologists direct anesthesia care.
  3. Death rates and failure-to-rescue rates are significantly lower when board-certified anesthesiologists supervise anesthesia care, compared to when mid-career anesthesiologists who are not board-certified supervise anesthesia care.

“Failure-to-rescue” implies that the anesthesia provider wasn’t successful in preventing a 1% panic moment from turning into a death statistic. The phrase “failure-to-rescue” is a key theme of this book.   Or more precisely, the phrase “successful rescue” is a key theme of this book.  When unexpected events occur during surgery–the 1% panic moments–your anesthesia provider needs to make the correct diagnosis and apply the correct therapeutic intervention to successfully rescue you.

When you meet your anesthesia provider prior to surgery, you’re about to trust your life to a stranger.  It matters who that stranger is.  As a patient, do you have any control over who your anesthesia provider will be?  If your surgery is an emergency at 2 a.m. when only one anesthesia provider is available, you will not.  But for most surgeries, and all elective surgeries, this book will teach you what to expect in anesthesia care, and what you can do to receive the best in anesthesia care.

Anesthesiologists must finish a minimum of 12 years of post-high school education–four years of college, four years of medical school, and four years of anesthesia internship and residency.  Nurse anesthetists must finish a minimum of 7 or 8 years of post-high school education –four years of college, a minimum of one year of critical care nursing experience, and two to three years of anesthetist training.  Anesthesia assistants must finish a minimum of 6 years of post-high school education–four years of college, and a 24-month program to obtain a Master’s degree as an anesthesia assistant.

Why would an individual choose to become an anesthesia provider?  It’s rare for teenagers or college students to dream of themselves as anesthetists.  Most popular television, movies, and fiction portray physicians in more conventional careers as surgeons, emergency room doctors, or in clinics.  Only 4% of medical school graduates choose anesthesiology.

I believe that individuals who choose anesthesia for their medical career are individuals who love the adrenaline rush of acute medical care.  Operating room anesthesia is a 180-degree turn from outpatient clinics, where practitioners take histories, order lab tests, write prescriptions for pills, and make appointments to see their patient weeks into the future.  Instead of  experiencing clinic visits over months or years, the anesthetic encounter is immediate care with immediate results.  Instead of a clinic patient returning weeks later for a recheck, the anesthetic patient wakes up from their anesthetic, and is discharged to their home or their hospital bed within hours.

I had already completed a three-year residency in internal medicine before I began my years of anesthesia training.  The diagnosis and treatment of complex medical patients appealed to me during internal medicine training, but I found the glacial pace of outpatient clinic care boring.  When I worked along side anesthesiologists in the intensive care unit, I was wooed by their skills in placing breathing tubes, intravenous and intra-arterial catheters, and their apparent calmness no matter how ill any patient was.  The world of acute care medicine is the world of airway, breathing, and circulation.  No specialty mastered all three as completely as anesthesiologists did.

The beginning of specialty training in anesthesia brings both intimidating power and overwhelming challenge.  For the first time in your life, your profession is to inject powerful medications into patients and watch them lose consciousness in seconds.  Administering your first anesthetic is an unforgettable experience.  One minute you are chatting with a patient, telling them to picture themselves relaxing on a beach in Hawaii, and the next minute you’ve rendered them unconscious and totally dependent on you to manage their airway, breathing, and circulation.

Moving from novice anesthesiologist trainee to experienced specialist requires hard work and patience.  On the first day of my anesthesia residency, I was so green I didn’t even know which hoses connected my anesthesia gas machine to the patient.  While learning the anesthesia profession, trainees must learn to endure the 99% boredom factor and glean their most valuable lessons during the 1% panic time.  During my first week of training, after my patient was asleep with the breathing tube inserted and the anesthesia gases flowing, my faculty member, Dr. Gregory Ingham, said to me, “This procedure will take four hours.”  He stood next to me for a minute or two in silence, then he said, “I hope you’re of a contemplative nature.”

Why would he say such a thing to a first-week trainee?  I believe he said it because much of operating room anesthesia care is tedious vigilance over a stable situation.  The anesthetist needs to cope with this fact, and hopefully even appreciate and enjoy the stability.

One week after my first exposure to Dr. Ingham, I was on call overnight in the hospital with him again.  We had four consecutive emergency cases, all young healthy men with injuries suffered in motor vehicle or motorcycle accidents.  Prior to the fourth case, at 2 a.m., I evaluated the patient and proposed my anesthetic plan.  “Our patient is a healthy 25-year-old male except for his open femur fracture,” I said.  “I thought we could do the anesthetic the same way we did the last three.”

Dr. Ingham nodded at me and sighed, “Richard, the patients are all different, but the anesthetics are all the same.”

Is this true?  Why would he make a statement like this to an impressionable young trainee?  There is a great deal of cynicism and battle fatigue in his comment, but a grain of truth.  Patients are all different, and many anesthetics are similar, but not every anesthetic is identical.  There are always choices for the anesthetist to make–crucial, life threatening decisions–every day, and on every case.  Decisions are made before the surgery, during the stable phases of the anesthetic, and during the 1% of moments when the anesthetist’s mind is reeling.

Patients see none of this.  Patients typically have ten minutes or less to meet their anesthesia provider.  In the internal medicine clinic, patients are awake for 100% of their face-to-face time with their doctor, but before a surgery the anesthesiologist has only a brief encounter to gain their patient’s trust.  In the internal medicine clinic, a large number of patients had chronic complaints that were difficult to cure:  chronic pains, high blood pressure, obesity, or diabetes.  The treatments usually involved a prescription for pills.  At the next office visit, the patient might feel better, but there was a significant chance that the patient would feel the same or feel no better, or perhaps they would have a new side-effect symptom from the pill you prescribed for them.

The anesthetic patient encounter is markedly different.  Prior to the surgery, most patients are anxious but they treat their anesthesiologist with soaring respect.  After the surgery, I find my patients are often gushing in their gratitude for the fact that I had delivered them safely back to consciousness.  In contrast to my sometimes-disappointed medicine clinic patients, the anesthetic patients are so upbeat that they make me feel wonderful.

When I describe the elation of interacting with anesthesia patients, my best friend offers a simple explanation:  “Of course your patients respect you before the surgery.  You’re about to knock them unconscious.  They’ll have no control and they’re completely dependent on you.  They want you to like them.  They want you to keep them alive.”

I believe that assessment is accurate.  Every patient wants the same thing from their anesthesia provider.  A successful, complication-free experience.  And that’s what happens . . . almost every time.

AN ANESTHESIA ANECDOTE: AN INEPT ANESTHESIA PROVIDER CAN KILL A PATIENT IN LESS THAN TEN MINUTES

THE ANESTHESIA CONSULTANT

An inept anesthesia provider can lose a patient’s life in less than ten minutes.

NEWSPAPER HEADLINE:  “ANESTHESIOLOGIST KILLS PREGNANT MOTHER DURING EMERGENCY SURGERY”

 

What follows is a true story, with the names changed to protect the identities of the individuals…

THE CASE:  At 1:30 a.m. during the 14th month of his anesthesia training, Dr. Tony Andrews had been on duty inside the hospital since 7:00 a.m. the previous day–a total of 19 hours already.  He’d spent most of that time inserting epidural anesthetics into the lower backs of laboring women on the obstetrics ward.  He went to sleep in his on-call room shortly after midnight, exhausted and hopeful that he’d sleep until dawn.

No such luck.  The telephone woke him up–the caller was Jennifer Rogers, an obstetrician with a busy private practice.  “I need you,” she said.  “I have a patient named Naomi Jordan who’s in labor with new onset of vaginal bleeding and late decels.  I need to do a stat C-section.”

A layman’s translation of Jennifer’s sentence was this:  Naomi Jordan was a laboring mother who was bleeding from her vagina.  Her baby’s heart rate was dropping to dangerously low levels (known as decelerations, or decels) during the late phase of each uterine contraction.  Dr. Rogers needed to do an emergency cesarean section, that is, she needed to cut open the lower abdomen of the mother, cut open the uterus (the medical term for the womb), and deliver the baby before the mother’s bleeding endangered the baby’s health.  An emergency cesarean section meant Dr. Andrews wouldn’t get back to sleep for three hours, minimum.

“How much blood has she lost?” he mumbled, trying not to fall back asleep.

“No more than a cup so far, but the bleeding could accelerate within minutes.”

“I’ll be there in a minute.”  Every cesarean section required an anesthetic–that’s why Dr. Rogers called Dr. Andrews.  He was sleeping in the hospital to be immediately available for urgent obstetric anesthetics.  He turned on the room light and rubbed my eyes.  His wrinkled blue scrubs served as both pajamas and surgical attire.  He put his sneakers back on and set out down the hallway to find his new patient.

Once Dr. Andrews was on his feet, the prospect of emergency surgery jolted him like a double espresso.  By the time he reached Naomi Jordan’s room, his head was clear and he’d forgotten what time of night it was.

Naomi Jordan was a round-faced black woman in her 20’s.  She was sitting up in bed and panting her way through a labor contraction.  She flared her lips and bared her teeth to endure the pain and grunted out, “Ow, ow, ow,” with each exhaled breath.  Naomi did little to hide her suffering, and paid no attention to Andrews when he entered the room.  A gray-haired labor and delivery nurse stood at the bedside.  The nurse held one hand on Naomi’s shoulder and focused her eyes on the fetal monitor screen that traced the baby’s heart rate.

Dr. Andrews opened the patient’s chart to skim through the pertinent details.  Naomi was 25 years old and healthy.  She was 9 months pregnant with her first child.  Her current weight was 185 pounds, and she was 5 feet 4 inches tall.  She’d been in labor for four hours, and her progress had been unremarkable until the last thirty minutes.

He sat down on the bed next to the patient, and said, “Hi, Ms. Jordon, I’m Dr. Andrews, one of the anesthesiologists who will be with you during your cesarean section.”  What he didn’t say was, “I’m a partially-trained anesthesiologist.”  It was his objective to appear confident and competent–she didn’t have to know he still had almost a year before he finished his training.  She didn’t have to know that his calm appearance was a guise that hid any uncertainty due to his inexperience.

Sweat dripped down Naomi’s cheeks and forehead.  Her eyes were dilated and wild.  She replied, “My baby girl.  I just want my baby to be all right.”

“We’ll do everything we can,” he said.  “You’re going to need be asleep for the surgery.  For most cesarean sections, anesthesiologists give an injection in the lady’s back–a spinal anesthetic–to numb you from your chest down.  But because you’re bleeding from below, that’s not a safe option.”

“I can see my baby as soon as I wake up, right?”

“Yes you can.  I’ll give you medicine into your I.V., and you’ll fall asleep in seconds.  When you wake up, the surgery will be finished.”  Dr. Andrews rattled through a brief explanation of the common risks, which included post-operative pain, nausea, and a sore throat from the breathing tube that I would place after she lost consciousness.  “It’s common for the bleeding to stop once you’ve delivered your baby.  It’s not likely that you’ll receive a blood transfusion, but if I need to give you blood to keep you safe, I will.”

She nodded her head and shivered.  “I’m scared to death,” she said.

“I’m not.  I’ll take good care of you.” He touched the back of her hand, and said, “I’ll be right back.”

He stepped out of her room to find a telephone.  This was his second and final year of anesthesia residency training, and he was the sole anesthesiologist on the obstetrics ward at 1:40 in the morning.   He had a faculty backup, Dr. Luke Harrington, who was at his home, presumably asleep.  It was time to end Dr. Harrington’s slumbers.

Dr. Andrews called Dr. Harrington and explained the urgent clinical situation.  Dr. Harrington said, “If she’s bleeding, she’ll need a general anesthetic.  I’ll be right in.”

When patients have significant bleeding, the volume of blood in their arteries and veins is depleted.  For most cesarean sections, anesthesiologists prefer to give a regional anesthetic (either a spinal anesthetic or an epidural anesthetic), that leaves the patient awake but numb from the nipples down.  Neither a spinal nor an epidural can be safely administered in a patient who is actively bleeding.  Spinal and epidural anesthetics relax the sympathetic nervous system and dilate both arteries and veins, lowering the blood pressure further.  Dilating arteries that are already emptied because of bleeding is dangerous, and can lead to cardiac arrest or death.

Dr. Andrews hung up the phone and returned to Naomi’s bedside.  The nurse was disconnecting the fetal monitors and readying the bed for transport to the operating room.  Together they rolled the gurney down the hallway, and into the operating room.  A surgical scrub technician and an operating room nurse were waiting for them inside the OR.  The nurses and Dr. Andrews pulled surgical masks over their faces.  Only Naomi Jordan stayed unmasked.  Her hands shook and her voice cracked.  “Is my baby still all right?  She’s going to be O.K., isn’t she?”

“We’re going to move ahead and deliver her as soon as we can,” Dr. Andrews said.  He hung her I.V. bottle on a pole next to the anesthesia machine and said, “Can you please move over from your bed to the operating room table?”

With a loud grunt and a louder moan, Naomi wiggled herself to her right from the hospital bed onto the narrow O.R. table.  She left behind a two-foot-wide circular stain of blood on the sheets of her bed–evidence of ongoing vaginal bleeding.  The sight of the pool of blood fed Dr. Andrews’ sense of urgency.  It looked like more than a cup had spilled onto the sheets.  How much blood had she lost?

He used his stethoscope to listen to Naomi’s chest, and confirmed that her heart tones and breath sounds were normal.  He asked her to open her mouth, and assessed how easy it would be to insert a breathing tube after he anesthetized her.  She had a short neck and a thick tongue, but otherwise he didn’t note anything exceptional about her mouth or airway.  Dr. Andrews went about his routine and attached a blood pressure cuff to her arm, electrocardiogram stickers to her chest, and an oximeter probe to her finger.

Her heart rate was fast at 120 beats per minute.  The elevated heart rate could be secondary to her anxiety, but it could be because her bleeding was ongoing and her heart was working hard to pump a depleted blood volume to her vital organs.

Her blood pressure was 100/55, a lower value than the last reading of 115/60 ten minutes earlier.  The low blood pressure worried him–it could be further evidence that her blood vessels were emptying as she continued to bleed.  The pulse oximeter on her finger gave a reading of 100%, indicating that her arterial blood was 100% saturated with oxygen–a good sign.

Naomi looked like she was ready to sit up and run out of the room.  “It’s freezing in here,” she said, glancing around the room at the anesthesia machines and the array stainless steel surgical tools laid out on the scrub table.  “I’m so scared.  Can’t my mom be in here with me?”

“No,” Dr. Andrews said as he loaded my syringes with anesthetic drugs.  “When patients are going to be asleep, it’s not safe for family to be in here observing.  You’re going to be all right.”

The operating room nurse pulled up Naomi’s gown and began painting the bulbous abdomen with Betadine, an iodine disinfectant soap.  Dr. Rogers entered the room. She was a trim, attractive woman in her thirties.  She grabbed Naomi’s left hand and wiped away the tears from her patient’s eyes. “We’ll take great care of you,” she said.  Naomi blinked hard and closed her eyes.

A female scrub tech unfolded a large blue sterile paper drape, and set it down over Naomi’s abdomen to cover the Betadine-painted skin.  The scrub tech’s job was to hang the drapes to isolate the surgical field, and after that to hand sterile instruments to the surgeon during the surgery. She handed one edge of the drape to Andrews, and he applied clamps to secure the drape to two tall metal poles to the left and right of the patient’s shoulders.  This configuration formed a wall of blue paper with Naomi’s head and the anesthesiologist on one side of the barrier, and the sterile surgical field on the opposite side.  Dr. Rogers reentered the operating room.  She’d left to scrub her hands, and now she donned the sterile gown and gloves of her trade.  She took her position on the left side of the patient’s abdomen, and looked Dr. Andrews in the eye.  “Are you ready to get her asleep?” she asked him.

“I’m still waiting for Dr. Harrington,” he said. “Otherwise I’m ready to go.”  He turned to the nurse and said, “Call the general O.R. and the ICU.  Find out if any other anesthesiologists are available to assist me.”

“Will do,” she said, and she picked up a phone.

It was 1:55 a.m.  Dr. Andrews had checked the necessary anesthesia equipment, and it was all present and in order: breathing tubes, laryngoscopes needed for inserting a breathing tube, multiple syringes loaded with anesthetic drugs, and the anesthesia machine capable of delivering mixtures of oxygen, nitrous oxide, and the potent anesthetic vapor called isoflurane.

He looked down at the spheres of sweat beading up on Naomi’s forehead.  She was breathing oxygen through a clear plastic mask.  Each time she exhaled, water vapor fogged the clear plastic of the mask in front of her mouth.

The surgeon looked at the clock and said, “I don’t have any monitor of the fetal heart tones at this point, so I have no idea if the baby’s all right.  The patient is still bleeding.  We need to get the kid out.”

Dr. Andrews’ head was spinning.  Where was Dr. Harrington?  Tony Andrews was 31 years old and had been an M.D. for over five years, but he’d never been in this exact situation without a faculty anesthesiologist before.  He was confident– he had plenty of medical experience. This was his second year of anesthesia residency training, and he’d administered about eight hundred anesthetics in the preceding thirteen months.  He’d done dozens of general anesthetics for cesarean sections just like this one, but he’d never done one alone.  He was nervous as hell, but was he certain that he could handle starting this case without Dr. Harrington in attendance?  The problem was . . . it was too risky to wait any longer.  The baby’s life was at stake.  The mother’s life was at stake.

The nurse interrupted his train of thoughts.  “The main O.R. has two fresh trauma patients,” she said.  “They don’t have any extra anesthesiologists to come up and help you.  And the ICU phone is busy.”

Dr. Andrews inhaled a big breath and blew it out through pursed lips.  He could think of no other alternative.  “O.K., I’m going ahead,” he said to the surgeon.  She nodded in affirmation.

“I need you to give the patient cricoid pressure as she goes to sleep,” Dr. Andrews said to the operating room nurse.  Cricoid pressure is a medical maneuver whereby an assistant presses down firmly on a specific spot on the patient’s anterior neck, called the cricoid cartilage.  This action compresses the patient’s esophagus below.  Compressing the esophagus prevents regurgitation of stomach contents into the throat and mouth.  The stomach of a pregnant woman empties slowly, and the anesthesiologist must assume the stomach is full of undigested food.  Regurgitated vomit in the patient’s airway and lungs can be lethal.

The letters A-B-C, abbreviations for the words Airway-Breathing-Circulation, summarize the management of every acute medical situation.  As soon as Naomi went to sleep and couldn’t breathe on her own, she needed an airway tube.  That’s the anesthesiologist’s job–Dr. Andrews was the only one in the operating room with the training and ability to insert the endotracheal tube.

He injected 20 milliliters of the hypnotic drug sodium pentothal into her I.V. over a three-second span of time, and then injected 4 milliliters of the muscle-paralyzing drug succinylcholine.

“You’re doing great.  Everything’s going to be all right,” he said to Naomi, a wish as much as a promise.  The nurse located the cricoid cartilage on Naomi’s neck, and pressed downward.

Sodium pentothal is a rapid-acting drug that induces unconsciousness.  Naomi’s eyes closed ten seconds after the injection.  The second drug, succinylcholine, also known as “sux,” is an ultra fast-acting muscle relaxant.  Intravenous sux renders all the muscles in the body flaccid within a minute.  This paralysis makes it possible for the anesthesiologist to insert a lighted instrument called a laryngoscope into a patient’s mouth, visualize the vocal cords in the patient’s larynx (the medical name for the voice box), and place a hollow breathing tube through the vocal cords into the trachea (the medical name for the windpipe).  The paralysis also makes it impossible for the patient to breathe on her own.

The operating room was quiet except for the beeping of Naomi’s pulse on my monitoring equipment.  Everyone was waiting for Dr. Andrews.  Surgery could not begin until he inserted the breathing tube.

Thirty seconds after he injected the sux, every muscle of Naomi’s body began to shiver in involuntary paroxysms.  The widespread contraction-then-paralysis of every skeletal muscle of Naomi’s body is a phenomenon known as fasciculation, a well-known and expected side effect of sux.  Watching an otherwise motionless patient fasciculate is a creepy experience–the patient’s body moves as if demon forces were tunneling beneath the surface of the skin.

Once the fasciculation ceased, Dr. Andrews knew his patient was paralyzed.  His heart thundered as he removed her oxygen mask.  He turned on the light on my laryngoscope and gripped the metal handle in his left fist.  After she fell asleep, Naomi’s lips and tongue collapsed against each other, obstructing any view of her teeth or inside her mouth.  Dr. Andrews first job was to pry the mouth open and insert the lighted metal laryngoscope blade between her incisors.  He followed the light as it illuminated her mouth and throat.  He was looking for the pearly white vocal cords that guarded the windpipe.  His initial search was futile–all he could see were the flabby pink tissues of her tongue and throat.  He pulled harder the laryngoscope handle in an effort to lever open the airway, but he still saw nothing but pink flesh.  He began to breathe faster, and sweat poured from his underarms.

At that moment, Dr. Andrews heard the sound that strikes terror into every anesthesiologist’s heart–a descending musical scale keeping time with every one of Naomi’s heartbeats.

The descending musical notes came from the medical monitoring device known as a pulse oximeter.  The pulse oximeter is the most vital and important monitor in any acute care medical setting.  The pulse oximeter records its signal from a clip placed across the tip of a patient’s finger.  One side of the clip is a red light emitting diode (LED), and the other side of the clip is a receptor that quantifies the amount of red light that passes through the patient’s fingertip.  A computer in the pulse oximeter filters out all the signals except for red light that pulsates.  The only source for pulsating red light in the fingertip is blood in the small arteries.  The pulse oximeter converts red hue of the pulsating arterial blood to a percentage of oxygen saturation in the blood, based on how red the blood is:

More oxygen in the blood => redder blood => an increased oxygen saturation of 90% or greater => the patient is safe.

Less oxygen => darker purple blood => an oxygen saturation lower than 90% => the patient’s life is in danger.

The pulse oximeter emits a beep tone with every measured heartbeat.  As Naomi’s oxygen saturation declined below 90%, the beeping note decreased in pitch.  As her lips turned blue before his eyes, the descending chromatic scale of the pulse oximeter announced that the blood in her fingertip contained less oxygen.  This also meant her heart and brain were receiving less oxygen.

At the same time, the rate of the oximeter beeps increased to over 130 beats per minute. Dr. Andrews’ own heart rate was higher than Naomi’s.  Naomi Jordon and her baby were dying in his hands, and it was up to him to step it up and save her.  It was up to Dr. Andrews to insert the breathing tube.

Instead, he panicked.

He repeated the same futile attempts to visualize her vocal cords.  He reinserted the same metal laryngoscope into her mouth and followed the illuminated trail of its flashlight bulb.  He was still looking for the two pearly white vocal cords and the blackness of the tracheal lumen between them.

Instead, all he saw were folds of pink tissues.

The menacing notes of the oximeter beeps descended further.  The patient was out of oxygen.  Dr. Andrews pushed the metal laryngoscope deeper into her throat in a desperation move to find the trachea.

“Can’t you intubate her?” Dr. Rogers asked.

Dr. Andrews was too stuck in his predicament to answer.  The pulse oximeter tone was deeper than he’d ever heard it.  He glanced up at the machine, and saw that the oxygen saturation was in the 50’s.

Incompatible with life.

I’ve killed her, he thought, and the vivid image of a newspaper headline filled his head: “ANESTHESIOLOGIST KILLS PREGNANT MOTHER DURING EMERGENCY SURGERY.”  At that second, Dr. Tony Andrews would have given anything to escape from that mess with Naomi Jordon alive and well.

Stupefied by failure, he didn’t know what else to do except to keep trying over and over to put the tube in.

THE RESCUE:  At that moment, Dr, Tony Andrews’ luck turned.  The outer door to the operating room opened, and Dr. Luke Harrington ran in, wearing the non-surgical attire of blue jeans and a faded blue polo shirt.  Street clothes were never allowed in the sterile confines of an operating room.  Dr. Harrington observed the chaotic scene through the operating room window that faced in from the outside hallway, and figured out there was no time for a wardrobe change.

Instead of screaming at me or asking questions, Dr. Harrington said, “Take the laryngoscope out of her mouth NOW.  Let’s put the anesthesia mask back over her face.”

Dr. Andrews complied.

“Hold the mask with two hands,” he said.  “Fit it in a good seal over her face, and I’ll squeeze the ventilation bag.”

Dr. Andrews pressed the clear plastic mask over her mouth and nose and held it in an airtight fashion, with one hand at 3 o’clock and one hand at 9 o’clock over each of her cheeks.  Dr. Harrington squeezed the ventilation bag, and by this technique they were able to force 100% oxygen through her upper airway into her lungs via bag-mask ventilation.

Of course, Dr. Andrews thought.  She was dying and turning blue.  I was supposed to stop the futile attempts to put in a breathing tube, and just do this.  Pump in oxygen via the facemask.

Dr. Andrews held his breath and looked up at the vital sign monitors.  Her oxygen saturation hung low, still in the 60’s.  Dangerously low.

His mouth was so dry that he couldn’t swallow.

Dr. Harrington remained impassive.  If he was worried, he wasn’t showing it.  He fixed his eyes on the oximeter numerical readout.

For the next sixty seconds Dr. Andrews’ mind echoed, God, please, God please. . . .  A full minute went by, and then note-by-note the beep tone of the oximeter rose in pitch, and the numeric readout climbed in parallel.  From 60%, the oxygen saturation rose to 66%, . . . 72%, . . . 83%, then 93%.

They’d done it!  With an oxygen saturation greater than 90%, her brain and heart were now receiving an adequate supply of oxygen.  The surgeon peered over the drapes at us.  She was still holding her scalpel dormant.  She couldn’t start the cesarean section until the anesthesiologists had safely placed the endotracheal tube.

Dr. Harrington asked Dr. Andrews, “What happened when you tried to intubate her?”

“I couldn’t see anything but pink tissues.”

Dr. Harrington lifted the mask away from her face, and opened her mouth to look inside.  He frowned and nodded.  “Let’s change her head position.  Get me two white towels.”

He had Dr. Andrews lift up Naomi’s shoulders, while he stuffed two folded white towels behind her neck.  Naomi Jordan’s head extended backwards and her mouth fell open for the first time.

“Looks better.  Try it again,” Dr. Harrington said. Dr. Andrews was surprised that he’d want him try again, since he’d done nothing right so far.  He wondered why Dr. Harrington didn’t just take over.

The patient’s oxygen saturation was up to 100%.   Dr. Harrington pushed another 10-milliliter bolus of sodium pentothal into the IV to keep Naomi asleep, and Dr. Andrews opened her mouth to try again.  This time, as he advanced the laryngoscope blade and light into her mouth, the anatomical landmarks were more obvious.  Past the base of her tongue, he located the epiglottis, the pink flap of tissue that closed off the windpipe each time she swallowed.  He was elated–he hadn’t seen any recognizable structures my last time in.  The larynx, the gateway to the trachea, lay just beneath the epiglottis.  Since neither light nor vision can travel in a curve, he needed to lift up the epiglottis to see past it.  He pulled hard on the laryngoscope handle toward the ceiling.  To his relief and amazement, he saw the black hole of the tracheal opening.

“I’ve got it,” Dr. Andrews said, his voice cracking.

“Here’s the tube,” Dr. Harrington said, as he handed Dr. Andrews the clear plastic endotracheal tube. Dr. Andrews fed the tube through her mouth, past the epiglottis and into the trachea.  Dr. Harrington injected 8 milliliters of air from an empty syringe into a portal on the tube.  This inflated a balloon near the distal tip of the tube, which formed a seal against the inner walls of Naomi’s trachea.

Dr. Harrington connected the endotracheal tube to the hoses from the anesthesia machine, and squeezed the ventilation bag.  The patient’s chest expanded. Dr. Andrews pressed his stethoscope against her chest and listened.  The breath sounds were prominent and conclusive.  The endotracheal tube was in the correct place.

“You can cut,” Dr. Harrington said to the surgeon.

Dr. Rogers turned her attention to the patient’s lower abdomen, and made a swift horizontal incision above the pubic bone.  Her assistant retracted the tissue layers as Dr. Rogers cut deeper inside the body.  Within five minutes, she’d controlled all the bleeding and exposed the anterior wall of the uterus.  A second incision cleaved the womb, and she reached inside to pull the baby out.  Within 30 seconds, she’d delivered the baby, cut the umbilical cord, and handed the baby off to the team of pediatricians ready to resuscitate her.

The anesthesiologists’ work wasn’t over after they placed the breathing tube.  They turned on a mixture of 50% nitrous oxide in 50% oxygen, and dialed in a 0.6% mixture of the anesthetic gas isoflurane.  These gases would keep Naomi asleep as the surgeon worked to sew her back together.

Across the room the pediatricians ventilated the baby with oxygen by mask.  Within 5 minutes the baby was pink and crying.  “Apgar scores are 2 and 9,” the pediatric resident said.  The Apgar score is a rating from 0 to 10, calculated one minute after birth and again at 5 minutes, used to quantify how healthy and vital the baby is.  The score is a sum of 0 – 2 points each for five different criteria, including Activity, Pulse, Grimace, Appearance, and Respirations.  The baby’s 5 minute Apgar score of 9 was nearly a perfect 10, and a sign that the baby had survived the birthing process without apparent harm.

Dr. Andrews thanked Dr. Harrington for his timely arrival. Dr. Andrews’ hands were still shaking, supercharged with the adrenaline that had poured into his system over the last hectic hour.

Sixty minutes later, the surgeon closed the last surgical incision, concluding the cesarean section. Dr. Andrews turned off the anesthetic gases.  Naomi Jordan opened her eyes, and Dr. Andrews removed the breathing tube.

“Is my baby girl here?” she asked.

“She’s right here,” Dr. Andrews said, and the pediatrician handed the infant to her mother.  Naomi cried tears of joy.  It was all Dr. Andrews could do to keep from crying along with her.

Dr. Harrington had rescued all three of them:  Naomi, her baby daughter, and Tony Andrews.

LESSONS LEARNED:  The Naomi Jordan story highlights three key issues:  1) the crucial importance of airway management, 2) surgery and anesthesia have risk, and(3) the problem of inexperienced anesthesia practitioners performing medical care they are not fully capable to handle.

(1)  The crucial importance of airway management:  Losing control of an unconscious patient’s airway is a hazard that every anesthetist dreads, every day, in every operating room.  Indeed, the most important skill an anesthesia provider learns is not how to administer powerful sleep drugs, but how to keep patients alive and well under the influence of powerful sleep drugs.  All major anesthetic drugs and gases cause profound depression of breathing and/or cardiac function.

Keeping the anesthetized patient’s airway open via a mask or a laryngeal mask airway or a breathing tube is a critical skill for every anesthesia provider.   If the airway closes, the brain is deprived of oxygen.  Irreversible brain damage can occur after as little as four minutes without oxygen.

(2)  The risks involved in surgery and anesthesia:  Deep down, every surgical patient has the same worry:  How safe is surgery and anesthesia?

Methods of evaluating anesthetic mortality are inexact and controversial.  In 1999 the Institute of Medicine published their report entitled To Err is Human: Building a Safer Health Care System.  In this report, the Committee on Quality of Health Care in America stated that, “anesthesia is an area in which very impressive improvements in safety have been made.”  The Committee cited anesthesia mortality rates that decreased from 1 death per 5,000 anesthetics administered during the 1980s, to 1 death per 200,000-300,000 anesthetics administered in 1999.  Keep in mind that this statistic reflects the frequency of all patients, healthy or ill, who die in the operating room.

This conclusion that anesthesia mortality has plummeted is not universal.  When mortality is defined as any death occurring within 48 hours following surgery, the statistics are much different.  In 2002, anesthesiologist Dr. Robert S. Lagasse of the Albert Einstein College of Medicine in New York published a study in Anesthesiology, the specialty’s leading journal, that challenged the Institute of Medicine report.

Lagasse presented data on surgical mortality from two academic New York hospitals between the years 1992 and 1999.  Mortality was defined as any death occurring within 48 hours following surgery.  There were 351 deaths in 184,472 surgeries–an overall surgical mortality rate of 1 death per 532 cases. Keep in mind that these were deaths within 48 hours–not deaths in the operating room.

Deaths related to anesthesia errors were much less–only 14 deaths out of 184,472 surgeries–a rate of 1 death per 13,176 cases.   Lagasse’s anesthesia-related mortality rate of 1 per 13,176 surgeries was significantly different that the Institute of Medicine’s rate of 1 death per 200,000-300,000 surgeries.  Lagasse wrote, “We must dispel the myth that anesthesia-related mortality has improved by an order of magnitude. Science does not support this claim.”

Lagasse compared anesthesia to the aviation industry: “The safety of airline travel, for example, has increased dramatically in this century, but since the 1960s there has been minimal improvement in fatality rates.  This may be due to the effect that improved safety technology has had on air traffic density.  Technology has made it possible to meet production pressures of the commercial airline industry by allowing more takeoffs and landings with less separation between aircraft.  With this increased aircraft density comes increased danger, thereby offsetting potential improvements in safety.  This may be analogous to the practice of anesthesiology in which improvements in medical technology have led to increased anesthetic management of older patients with significantly more concurrent disease.”

Today’s surgery patients are sicker than ever.  About 5% of all surgical patients die within one year of surgery.  For patients over the age of 65 years, 10% of all surgical patients die within one year of surgery.

Naomi Jordan was healthy, and a cesarean section is a common surgical procedure.  But her case was an emergency procedure, and general anesthesia for cesarean section is known to be a high risk for airway problems because pregnant women have narrowed upper airways, decreased oxygen reserves, and stomachs that do not empty normally.  A 2003 study showed that a difficult or failed intubation following induction of general anesthesia for cesarean section was the number-one factor in anesthesia-related maternal complications.

Because of this, the use of general anesthesia for cesarean sections has declined.  In a Harvard study published in 1998, only 3.6% to 7.2% of cesarean sections were done under general anesthesia.  Difficult intubations were frequently unexpected, as was the case for Naomi Jordan, and one failed intubation resulted in the mother’s death.

Whenever possible, the safest anesthetic choice for cesarean section is a spinal or an epidural block, in which the anesthetist injects a local anesthetic drug via a needle inserted in the low back area.  This numbs the mother from her nipples to her toes, and she stays awake and breathes on her own during surgery.

(3) Inexperienced anesthesia practitioners performing medical care they are not fully capable to handle:  During the first twelve months of a physician’s anesthesia residency, each trainee is closely mentored and restricted to easier surgeries if possible.  Each year in July, new residents enter each residency program and existing residents are advanced from first-year residents to second-year residents, while second year residents become third-year residents.  Each July, every anesthesia trainee faces a new tier of responsibilities and more challenging cases.  The Naomi Jordan case occurred in August, when Dr. Tony Andrews was inexperienced and less than two months into the more challenging second year of residency.  In a teaching hospital, July and August are the least desirable months to be a patient.

Within a few years of Dr. Andrews’ incident, the hospital he trained at changed its staffing, and made it mandatory that an anesthesia faculty member stayed in the hospital all night.  Inexperienced residents would never be called on to handle emergencies alone–a good idea that grew out of the Naomi Jordan case and others.  In addition, the American Board of Anesthesiology added an additional year of required training to all anesthesiologist residencies, so every anesthesiologist left their residency with a minimum of three years of training post-internship instead of just two.

Prior to the Naomi Jordan case, Dr. Andrews was both inexperienced and cocky–a bad combination.  He screwed up the management of her airway, but Dr. Harrington rescued him, and the outcome was excellent. If Dr. Andrews had harmed Naomi Jordan, he would have been known as the anesthesiologist that bumped off a healthy patient.  Despite his previous 800 uneventful anesthetics up to that night, he would be remembered for the one that went bad.  The Naomi Jordan case taught Dr. Andrews a lesson he never forgot.  While he never lost control of another patient’s airway in his years of anesthesia practice after the Jordan case, that wasn’t the lesson he learned.  The lesson Dr. Andrews learned was a lesson every anesthesia provider eventually comes to accept:

You’re only as good as your last anesthetic

Published in September 2017:  The second edition of THE DOCTOR AND MR. DYLAN, Dr. Novak’s debut novel, a medical-legal mystery which blends the science and practice of anesthesiology with unforgettable characters, a page-turning plot, and the legacy of Nobel Prize winner Bob Dylan.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

Dr. Nico Antone, an anesthesiologist at Stanford University, is married to Alexandra, a high-powered real estate agent obsessed with money. Their son, Johnny, an 11th-grader with immense potential, struggles to get the grades he’ll need to attend an Ivy League college. After a screaming match with Alexandra, Nico moves himself and Johnny from Palo Alto, California, to his frozen childhood home of Hibbing, Minnesota. The move should help Johnny improve his grades and thus seem more attractive to universities, but Nico loves the freedom from his wife, too.

Hibbing also happens to be the hometown of music icon Bob Dylan. Joining the hospital staff, Nico runs afoul of a grouchy nurse anesthetist calling himself Bobby Dylan, who plays Dylan songs twice a week in a bar called Heaven’s Door. As Nico and Johnny settle in, their lives turn around; they even start dating the gorgeous mother/daughter pair of Lena and Echo Johnson. However, when Johnny accidentally impregnates Echo, the lives of the Hibbing transplants start to implode. In true page-turner fashion, first-time novelist Novak gets started by killing soulless Alexandra, which accelerates the downfall of his underdog protagonist now accused of murder. Dialogue is pitch-perfect, and the insults hurled between Nico and his wife are as hilarious as they are hurtful: “Are you my husband, Nico? Or my dependent?”

The author’s medical expertise proves central to the plot, and there are a few grisly moments, as when “dark blood percolated” from a patient’s nostrils “like coffee grounds.” Bob Dylan details add quirkiness to what might otherwise be a chilly revenge tale; we’re told, for instance, that Dylan taught “every singer with a less-than-perfect voice…how to sneer and twist off syllables.” Courtroom scenes toward the end crackle with energy, though one scene involving a snowmobile ties up a certain plot thread too neatly. By the end, Nico has rolled with a great many punches.

Nuanced characterization and crafty details help this debut soar.

HOW TO START AN I.V. CATHETER ON A PATIENT WITH DIFFICULT VEINS

THE ANESTHESIA CONSULTANT

In this column, I’ll describe the best approach to starting a difficult IV in a patient with small, deep, or hidden veins. This information is based on my experience in personally starting IVs on over 25,000 surgical patients in 34+ years as a clinical anesthesia attending.


DSCN0177

Anesthesiologists become experts at inserting an intravenous (I.V.) catheter.  In my career of 20,000+ anesthetics, I’ve started at least one I.V. per patient, and some cases required more than one I.V.  Some I.V’s are easy, and would present no challenge to a first-year nursing student, but some patients have veins that are small, deep, rolling, invisible, or scarred over, and only an expert will succeed.

Almost every adult anesthetic begins with the intravenous injection of sedative drugs, so every anesthesiologist needs to become expert in I. V. insertion.  As a demonstrative case, let’s tackle a world-class difficult situation:

Your patient is obese, weighing in at 300 pounds, and her arms are cylinders of fatty tissue.  She has a past history of surgery for breast cancer, and she had the lymph nodes removed under her left arm.  Therefore, I.V. attempts in her left arm are prohibited.  In addition, she had intravenous chemotherapy for months, which used up every decent vein in her right arm.

Here are my time-tested tips to successfully locate a vein and insert the I.V. on a difficult patient such as this:

  1. Lie the patient down, supine and horizontal.  Blood will pool where gravity takes it.  If a patient is sitting upright, or has their legs dangling, the blood will pool in dependent regions such as the veins of the legs, rather than the veins of the upper extremities where you are looking.
  2. Apply a standard rubber tourniquet to the upper arm.  Then, on top of this tourniquet, apply the blood pressure cuff from an automated blood pressure machine.
  3. Activate the blood pressure cuff in “Stat” mode, or repeatedly inflate the cuff in “Manual” mode.  The pneumatic blood pressure cuff is a superior venous tourniquet, and will be most effective in making even small veins grow prominent.
  4. Examine the arm carefully for the best vein.  Do this by both inspection and palpation.  Sometimes the cord of the vein can be felt, even when it can not be seen.  Rather than sticking the patient’s arm in multiple places, over and over, until she looks like a pin-cushion, be patient and do not start until you’ve found the very best location.
  5. Stimulate the skin over this vein by snapping your forefinger at the site.  This local stimulation makes veins grow, perhaps by releasing a regional veno-dilator, or by blocking a regional veno-constrictor.  All I can tell you is that, whatever the mechanism, this technique definitely works.
  6. Choose a standard I.V. catheter, either a 20-gauge or 22-gauge.  Butterfly needles are NOT preferred, because they require leaving a needle in the small vein, rather than the plastic I.V. catheter.
  7. ALWAYS anchor the skin over the vein by pulling distally with your non-dominant thumb, while you insert the I.V. catheter with your dominant hand.  This anchoring and stretching of the skin distally prevents the vein from rolling or moving during your insertion attempt.DSCN0160
  8. When you first hit the vein, and blood begins to flow into the hub of your catheter, you MUST advance the device an additional 1-3 millimeters before you attempt to advance the catheter forward over the needle into the vein.  And you MUST NOT move the non-dominant thumb away from its task of stretching the skin distally, so that the vein stays stationary. The I.V. catheter device is a catheter-over-a-needle device.  When the needle tip first enters the vein, the catheter tip is not in the lumen of the vein yet.  The  1-3 millimeter advance moves the tip of the plastic catheter into the vein.DSCN0160
  9. Patients have four extremities.  If you are unsuccessful in locating a vein in either arm, you can move to the foot and ankle region to start an I.V. there.  Follow the same steps outlined above.

10. If you can not locate a vein in any extremity, consider the external jugular veins on the side of the patient’s neck.  With the patient positioned slightly head down, these veins are often prominent.  The external jugular vein swells when the patient performs a Valsalva maneuver, such as when you ask them to “bear down as if you are having a bowel movement.”  You do not need to start a central venous catheter (CVC) in the external jugular vein.  A simple 1- ¼ inch, 20-gauge peripheral I.V. catheter will suffice.  Because the size and diameter of the external jugular vein is larger than most arm veins, and because the external jugular vein is usually quite superficial, cannulating this vein can be very easy in skilled hands.  I attach a 3 c.c. syringe onto the hub of the intravenous catheter device before I attempt the insertion, and then I aspirate back with negative pressure as I advance the device.  Once the catheter is inside the external jugular vein, the syringe will fill with blood, and you can advance the catheter into the vein.  I usually fixate the catheter with tape, rather than suturing the catheter in place.

Those are my tips for difficult I.V. inserting.  Follow these steps, and with experience and patience, you will become the intravenous-insertion expert at your hospital.

DO ANESTHESIOLOGISTS HAVE THE HIGHEST MALPRACTICE INSURANCE RATES?

THE ANESTHESIA CONSULTANT

How high are anesthesiology malpractice rates? Do Anesthesiologists pay the highest malpractice insurance rates?

In a word, “No.”

Anesthesia mishaps can lead to critical events such as death or coma, but in recent decades improvements in operating room technology and education have led to fewer such events.

Prior to 1985, anesthesia malpractice claims for death or brain death were most often due to lack of oxygen the patient’s heart or brain.  Two significant breakthroughs arrived in the 1980’s to help anesthesiologists care for you:  1) the pulse oximeter, and 2) the end-tidal carbon dioxide monitor.

The pulse oximeter, developed by Nellcor and Stanford anesthesiologist William New, M.D., is a device that clips to a patient’s fingertip.  A light-emitting diode shines a red light through the finger, and a sensor on the opposite side of the finger measures the degree of redness in the pulsatile blood flow within the finger.  The more red the color of the blood, the more oxygen is present.  A computer in the pulse oximeter calculates a score, called the oxygen saturation, which is a number from 0-100%.  An oxygen saturation equal to or greater that 90% correlates with a safe amount of oxygen in the arterial blood.  A score of 89% or lower correlates with a dangerously low oxygen level in the blood.  The pulse oximeter monitor enables doctors to know, second-to-second, whether a patient is getting sufficient oxygen.  If the oxygen saturation goes below 90%, doctors will act quickly to diagnose and treat the cause of the low oxygen level.  A patient can usually sustain a short period low oxygen saturation, e.g. up to 2 or 3 minutes, without permanent damage to the brain or cardiac arrest by an oxygen-starved heart.

The end-tidal carbon dioxide (CO2) monitor is a device that measures the concentration of CO2 in the gas exhaled by a patient on every breath.  During normal ventilation, every exhaled breath contains CO2.  When no CO2 is measured, there is no ventilation, and the doctor must act quickly to diagnose and treat the cause of the lack of ventilation.

Prior to the invention of these two monitors, it was possible for an anesthesiologist to mistakenly place a breathing tube in a patient’s esophagus, instead of the trachea, and not know of the error until the patient sustained a cardiac arrest.  With the addition of the two monitors, the lack of CO2 (there is no CO2 in the stomach or esophagus) from the end-tidal CO2 monitor immediately indicates that the tube is in the wrong  place.  The anesthesiologist can then remove the tube, resume mask ventilation with oxygen, and attempt to replace the tube into the windpipe.  If the oxygen level to the patient’s blood dips below 90%, this is a second piece of data that indicates that the patient is in danger of brain damage or cardiac arrest.

In addition, in the early 1990’s the American Society of Anesthesiologists created the Difficult Airway Algorithm, which is a step-by-step approach for anesthesiologists to follow when the task of placing a breathing tube for an anesthetic is challenging or difficulty.  This Algorithm dictates a standard of care for practitioners, and this advance in education lowered the number of mismanaged airways.

In the 1980’s, surgical anesthesia claims were 80% of closed malpractice claims against anesthesiologists (American Society of Anesthesiologists Closed Claims database).  By the 2000’s, this number dropped to 65%.   Brain damage represented 9% of claims, and nerve injury accounted for 22% of claims (23% were permanent and disabling, including loss of limb function, or paraplegia or quadriplegia)  Less common claims were airway injury (7% of claims), emotional distress, (5% of claims), eye injuries including blindness (4% of claims), and awareness during general anesthesia (2% of claims).

Decreasing anesthesiologist malpractice premiums reflect the decrease in the number of catastrophic anesthesia claims for esophageal intubation, death, and brain death.

In 1985, the average malpractice insurance premium was $36,224 per year for a $1 Million per claim/$3 Million per year policy.   By 2009, this decreased to $21,480, a striking 40% drop.(Anesthesia in the United States 2009, Anesthesia Quality Institute)

Specialties with the highest risk of facing malpractice claims are neurosurgery (19.1 percent), thoracic and cardiovascular surgery (18.9 percent) and general surgery (15.3 percent). Specialties with the  lowest risks are family medicine (5.2 percent), pediatrics (3.1 percent) and psychiatry (2.6 percent).  Anesthesiologists rank in the middle of the pack, at 7%.  (Malpractice Risk According to Physician Specialty, Jena, et al, N Engl J Med 2011) From 1991 to 2005, this article identified 66 malpractice awards that exceeded $1 million dollars, which accounted for less than 1% of all payments. Obstetrics and gynecology accounted for the most payments (11), followed by pathology (10), anesthesiology (7), and pediatrics (7).

The take-home message is that anesthesia has serious risks, but those risks have decreased significantly in recent years because of improvements in monitoring and education.  Compared to other specialties, the risk of an anesthesiologist being sued is about average among American medical specialties.

DO YOU NEED AN ANESTHESIOLOGIST FOR A COLONOSCOPY?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group
Richard Novak, MD is a Stanford physician board certified in anesthesiology and internal medicine.Dr. Novak is an Adjunct Clinical Professor in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, the Medical Director at Waverley Surgery Center in Palo Alto, California, and a member of the Associated Anesthesiologists Medical Group in Palo Alto, California.

THE ANESTHESIA CONSULTANT

Do you need an anesthesiologist for a colonoscopy?  The answer is:  it depends. It depends on 1) your health, 2) the conscious sedation skills of your gastroenterologist, and 3) the facility you have your colonoscopy at.

 

1)  YOUR HEALTH. The majority of colonoscopies in the United States are performed under conscious sedation.  Conscious sedation is administered by a registered nurse, under specific orders from the gastroenterologist.  The typical drugs are Versed (midazolam) and fentanyl.  Versed is a benzodiazepine, or Valium-like medication, that is superb in reducing anxiety, sleepiness, and producing amnesia.  Fentanyl is a narcotic pain reliever, similar to a short-acting morphine.  The combination of these two types of medications renders a patient sleepy but awake.  Most patients can minimal or no recollection of the colonoscopy procedure when under the influence of these two drugs.  I can speak from personal experience, as I had a colonoscopy myself, with conscious sedation with Versed and fentanyl, and I remembered nothing of the procedure.

If you are a reasonably healthy adult, you should be fine having the procedure under conscious sedation.  Patients with high blood pressure, diabetes, asthma, obesity, mild to moderate sleep apnea, advanced age, or stable cardiac disease are have conscious sedation for colonoscopies in America every day, without significant complications.

Certain patients are not good candidates for conscious sedation, and require an anesthesiologist for sedation or general anesthesia.  Included in this category are a) patients on large doses of chronic narcotics for chronic pain, who are tolerant to the fentanyl and are therefore difficult to sedate, b) certain patients with morbid obesity, c) certain patients with severe sleep apnea, and d) certain patients with severe heart or breathing problems.

2)  THE CONSCIOUS SEDATION SKILLS OF YOUR GASTROENTEROLOGIST.  Most gastroenterologists are comfortable directing registered nurses in the administration of conscious sedation drugs.  Some, however, are not.  These gastroenterologists will disclose this to their patients, and recommend that an anesthesiologist administer general anesthesia for the procedure.

3) THE FACILITY YOU HAVE YOUR COLONOSCOPY AT.  Most endoscopy facilities have nurses and gastroenterologists comfortable with conscious sedation.  Some do not.  The facility you are referred to may have a consistent policy of having an anesthesiologist administer general anesthesia with propofol for all colonoscopies.  If this is true, they should disclose this to you, the patient, before you start your bowel prep for the procedure.  A facility which always utilizes general anesthesia means that you, the patient, will incur one extra physician bill for your procedure, from an anesthesiologist.

I refer you to an article from the New York Times, which summarizes this phenomenon in the New York region:

One last point: If the drugs Versed and fentanyl are used, there exist specific and effective antidotes for each drug if the patient becomes oversedated. The antagonist for Versed is Romazicon (flumazenil), and the antagonist for fentanyl is Narcan (naloxone). If these drugs are injected promptly into the IV of an oversedated patient, the patient will wake up in seconds, before any oxygen deprivation affects the brain or heart.

Propofol, however, has no specific antagonist. Propofol only wears off as it is redistributed out of the blood stream into other tissues, and its blood level declines. A propofol overdose can cause obstruction of breathing, and/or depression of breathing, such that the blood oxygen level is insufficient for the brain and heart. The Food and Drug Administration (FDA) mandates that a Black Box warning be included in the packaging of every box of propofol. That warning states that propofol “should be administered only by persons trained in the administration of general anesthesia and not involved in the conduct of the surgical/diagnostic procedure.”

Anesthesiologists are experts at using propofol. I administer propofol to 99% of my patients who are undergoing general anesthesia for a surgical procedure. Anesthesiologists are experts at managing airways and breathing. Individuals who are not trained to administer general anesthesia should never administer propofol to a patient, in a hospital or in an outpatient surgery center.

I serve as the Medical Director of an outpatient surgery center in Palo Alto, California. We perform a variety of orthopedic, head and neck, plastic, ophthalmic, and general surgery procedures safely each year. In addition, our gastroenterologists perform thousands of endoscopies each year. I review the charts of the endoscopy patients as well as the surgical patients prior to the procedures, and in our center, approximately 99% of endoscopies can be safely performed under Versed and fentanyl conscious sedation, without the need for an anesthesiologist attending to the patient.

If you have an endoscopy, ask questions. Will you receive conscious sedation with drugs like Versed and fentanyl, or will an anesthesiology professional administer propofol? You deserve to know.

THE ANESTHESIA CONSULTANT

The past 25 years brought remarkable advances in clinical anesthesia practice, including pulse oximetry, end-tidal gas monitoring, propofol, and the laryngeal mask airway.  I posed this question to our Stanford anesthesia faculty who specialize in private practice:  In your opinion, what are the most important problems for anesthesia to address in the next 25 years?

Their answers:   “I think medicine as I have known it in my career will be unrecognizable 25 years from now.  There may be a few well-trained anesthesiologists who provide one-on-one anesthesia for the few patients who are willing to pay for it.  Our society has decided that it doesn’t want to pay for this kind of care for everyone.  I think the systems for providing anesthesia care will be unrecognizable to us in 25 years.   Since this change is going to come whether or not we like it, I would like to see our excellent academic Anesthesia Departments lead the way.  It is time for anesthesia leaders to take over the training of all those who provide anesthesia care so that we can maintain and improve the scientific advances that have been made in the last 25 years.   I think we all agree that some practitioners are over-trained and some under-trained for what they do for most of their careers.  I would like to see more sub-specialization earlier in training.  I would like to see our academics come up with possible solutions to providing high quality anesthesia care in a more cost effective way.  I think real team approaches, robotics and advances in information technologies should be tried to accomplish this goal.   If we don’t come up with more cost-effective ways it will be mandated by those who pay the bills, and I don’t think we will like their solutions.”    Lynn Rosenstock, M.D.  Past-President, Santa Clara County Medical Association;  Past-President, Associated Anesthesiologists Medical Group (AAMG), Stanford.

“I think economic pressures are driving academicians to practical efficiency and marketing pressures are driving private practitioners to offer ‘state of the art.’   In terms of tools that we use, the next 25 years will hopefully reveal enough understanding of mechanisms of consciousness, memory, sleep, and pain to allow us to have medications and techniques to more precisely target cells with minimal damage.  Real time 3-D Echo and 4-D MRI will finally get the resolution and size reduction needed for usage.  Robotic and mobile miniaturized anesthesia machines are likely coming down the pipeline too.”  Charles Wang, M.D. Department of Anesthesia, Palo Alto Medical Clinic (PAMC)..

“I hope that major improvements in pain management for the post-op patient come along before we retire.”  Bruce Halperin, M.D. AAMG.

“Problems will be:  1) to continue to increase safety while being pressured to do more for less;  and  2) to continue to train future generations of anesthesiologists when staffing and research needs at university settings don’t allow for significant one-to-one teaching.  Residents often provide manpower first and receive education as a secondary benefit.”  Chris Cartwright, M.D., PAMC.

“My thoughts are that we will find opioids without respiratory depression, and be able to use them to decrease the risk of anesthesia so that anybody can do anesthesia for any patient. That is my guess.” Joe Weber, M.D.  PAMC.

“I think that the biggest problem to be addressed in the next 25 years is finding drugs with specific desirable effects, without the side effects we deal with now, such as respiratory depression and nausea.   I am sure that more receptor-specific drugs will be in use by then.”Mike Cully, Hoag Hospital, Newport Beach.
“First, I would expect the problems of the three ‘R’s’:    Retirement, Recruitment, and Retention of anesthesiologists.  Second, I foresee models of delivering care to maximize physician extenders . . . yes, non-M.D. providers of care.   Third, there will be more delivering of care outside of our traditional settings.   Fourth, there will be more partnerships between physicians and care settings . . . i.e. the foundation model for delivery of care.   Fifth,  I expect the digitalization of information and record keeping, and finally, the impact of totally noninvasive surgery that does not require any anesthesia!”  David Berger, M.D.  Alta Bates Hospital.

“I think the biggest problem our specialty will face in the next two and a half decades is an indirect result of the epoch-changing advances you site prior to your question.   I suggest that our specialty is becoming complacent and apathetic and developing a dangerous attitude of entitlement.  The problem is the preservation of our professional status as physician specialists and our individual professionalism, ethics, and autonomy.  These things are the soul and core of what it means to be a physician, and are being eroded by the increasing power and influence of corporate business in medicine, and the ever tightening choke hold of governmental regulation.  There are a number of reasons why the practice of anesthesiology is particularly vulnerable in a way that our surgical colleagues and other physicians are more insulated.  We can accelerate this process of degradation by making short-sighted choices, or become proactive, patient advocacy oriented participants in the evolution of American medicine.  This must be a specialty-wide movement, however, not just limited to the few who are involved beyond one’s own narrow and immediate self interest, for us to successfully maintain the achievements of which we are so proud.”  Mark Singleton, M.D.,  Good Samaritan Hospital Group, San Jose.
