“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!

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:

Comment: A & A (as this journal is referred to in our profession) is an outstanding publication, second only to Anesthesiology.

ONE: ANESTHESIOLOGY. Per their website, “ANESTHESIOLOGY leads the world in publishing and disseminating the highest quality work to inform daily clinical practice and transform the practice of medicine in the specialty. . . . Founded in 1940, ANESTHESIOLOGY is the official journal of the American Society of Anesthesiologists but operates with complete editorial autonomy, with an independent and internationally recognized Editorial Board.” Comment: Anesthesiology is the blueprint for what a 21st century journal should  be, mixing breakthrough science and clinical studies with the all-important American Society of Anesthesiologist standards, guidelines, and practice parameters which define our profession.

My advice? Be intellectually curious about all things related to anesthesiology. Use PubMed and Google to look up questions you want answered. You’ll be directed to many of the publications above, and you’ll be a smarter clinician as a result.

In addition:  There are dozens of anesthesia textbooks. I’ve ranked the Top 11 Anesthesia Textbooks in a previous column.

THE ANESTHESIA CONSULTANT

In 1997 the IBM computer Deep Blue beat world chess champion Gary Kasparov head to head.  Is it feasible that CHATGPT, this decades artificial intelligence wunderkind, can equal or better a physician anesthesiologist? I entered three anesthesia consultations into CHATGPT, one preoperative, one intraoperative, and one postoperative. Is CHATGPT as good as an MD? Let’s look at what the computer answered:

PREOPERATIVE QUESTION

An 80-year-old woman with congestive heart failure gets short of breath walking up one flight of stairs. She needs to have her gallbladder removed. What sort of preoperative tests or therapies should this patient have before surgery?

 

CHATGPT: For an 80-year-old woman with congestive heart failure (CHF) who needs to undergo gallbladder removal surgery, it is essential to conduct a thorough preoperative evaluation to assess her overall health status and identify any potential risks. The specific evaluation required may vary depending on the patient’s medical history, the severity of the CHF, and the recommendations of the healthcare team involved. However, here are some general aspects that may be considered:

  1. Cardiac Evaluation: Given the patient’s CHF and symptoms of shortness of breath, it’s important to assess her cardiac function comprehensively. This may involve an electrocardiogram (ECG) to evaluate heart rhythm, an echocardiogram to assess heart structure and function, and possibly additional tests such as stress testing or cardiac catheterization, depending on the severity of her symptoms and the presence of any known cardiac conditions.
  2. Pulmonary Evaluation: Since the patient experiences shortness of breath, it may be necessary to evaluate her lung function. Pulmonary function tests, such as spirometry, may be conducted to assess lung capacity and function.
  3. Lab Tests: Routine blood tests may be performed to assess the patient’s overall health and check for any abnormalities that could impact surgery. This may include a complete blood count (CBC), comprehensive metabolic panel (CMP), coagulation profile, and other specific tests as deemed necessary.
  4. Imaging Studies: Depending on the patient’s medical history and symptoms, imaging studies like an abdominal ultrasound or a computed tomography (CT) scan may be ordered to confirm the diagnosis of gallbladder disease and assess its severity.
  5. Medication Review: A review of the patient’s current medications, including those used to manage her CHF, is crucial to ensure they are optimized for the surgery. Medications may need to be adjusted or temporarily stopped to minimize potential risks during the procedure.
  6. Anesthesia Evaluation: An evaluation by an anesthesiologist is important to assess the patient’s readiness for anesthesia and determine the most appropriate anesthesia plan for her, taking into account her cardiac condition and any other medical considerations.

It’s important to note that this is a general outline, and the specific preoperative evaluation for the patient should be determined by her healthcare team, including her primary care physician, surgeon, cardiologist, and anesthesiologist. They will consider her individual medical history and unique circumstances to ensure a safe and successful surgery.

 

INTRAOPERATIVE DECISION

A 60-year-old man with a history of hypertension is having a knee arthroscopy surgery under general anesthesia. In the middle of the anesthetic, his heart rate drops to 20 beats per minute, his blood pressure drops to unmeasurable, and he no longer has peripheral pulses. What do you think is going wrong, and what should be done do to save this man?

CHATGPT: I’m not a doctor, but the symptoms you described during the anesthetic suggest a severe and potentially life-threatening condition. This could indicate a cardiac event or a complication related to the anesthesia. One possible explanation for the sudden drop in heart rate, blood pressure, and loss of peripheral pulses is a condition called “bradycardia with hypotension” or “bradycardia-induced hypotension.”

In this situation, it’s crucial for the medical professionals involved to take immediate action. Here are some general steps that might be considered:

  1. Alert the medical team: The anesthesiologist or healthcare providers in the operating room need to be notified immediately about the patient’s deteriorating condition. The surgeon and additional medical personnel may also be called upon for assistance.
  2. Assess the airway, breathing, and circulation (ABCs): Ensure that the patient’s airway is clear and breathing is supported. Provide supplemental oxygen if necessary. Assess circulation and check for the presence of a pulse. If the patient is unresponsive or there is no pulse, initiate cardiopulmonary resuscitation (CPR) immediately.
  3. Notify the code team: If the patient remains unresponsive and pulseless, it may be necessary to activate a “code blue” or similar emergency response to involve a specialized team experienced in resuscitation procedures.
  4. Perform advanced cardiac life support (ACLS): Healthcare providers trained in ACLS protocols will initiate resuscitation measures, including chest compressions, defibrillation (if indicated for certain types of cardiac rhythms), and administration of medications such as epinephrine to help restore circulation.
  5. Identify and address potential causes: Once the patient’s vital signs have stabilized or as the resuscitation efforts continue, the medical team will work to identify the underlying cause of the cardiac event. This may involve evaluating the patient’s medical history, reviewing medications, and conducting further diagnostic tests such as an electrocardiogram (ECG) or blood tests.

It’s important to note that the above steps are general guidelines and the specific actions taken may vary depending on the patient’s condition, the resources available, and the expertise of the medical team on-site. In such a critical situation, the immediate focus will be on stabilizing the patient and providing appropriate resuscitation efforts to restore circulation and address any life-threatening issues.

 

POST ANESTHESIA EMERGENCY

In the recovery room after a tonsillectomy, a 5-year-old child coughs up blood, becomes short of breath, and becomes unconscious. What is probably going on, and what should be done to save this child?

CHATGPT: I’m not a doctor, but the symptoms you described following a tonsillectomy can be indicative of a serious complication known as postoperative hemorrhage. In this situation, it’s crucial to seek immediate medical attention. Here are some general steps that might be considered:

  1. Activate the emergency response: Alert the medical staff immediately about the child’s deteriorating condition. Nurses and physicians in the recovery room should be notified, and additional assistance may be needed, such as calling a code or emergency response team.
  2. Ensure a patent airway and support breathing: Assess the child’s airway and breathing. If the child is experiencing difficulty breathing or is unresponsive, the healthcare providers should take steps to establish and maintain a clear airway. They may administer oxygen and provide respiratory support if necessary.
  3. Control bleeding: Postoperative hemorrhage can cause significant blood loss, leading to the symptoms you described. The doctors should perform a thorough examination to identify the source of bleeding and take appropriate measures to control it. This may involve suctioning the blood from the child’s mouth, using medications to constrict blood vessels (such as topical epinephrine), or applying direct pressure to the bleeding site.
  4. Administer fluids and blood products: If the child is experiencing significant blood loss, intravenous fluids and blood products may be necessary to stabilize their condition and restore blood volume.
  5. Provide immediate resuscitation measures: If the child becomes unconscious or experiences cardiac arrest, cardiopulmonary resuscitation (CPR) should be initiated immediately. Healthcare providers trained in pediatric resuscitation will perform chest compressions, provide assisted ventilation, and administer medications as required.
  6. Prepare for surgical intervention: Depending on the severity of the bleeding and the child’s condition, emergency surgical intervention may be necessary to control the bleeding. The surgical team will be assembled, and the child will be transferred to the operating room for further assessment and management.

It’s important to note that the above steps are general guidelines, and the specific actions taken may vary depending on the child’s condition, the resources available, and the expertise of the medical team on-site. In such a critical situation, the immediate focus will be on stabilizing the child, controlling the bleeding, and providing any necessary resuscitation efforts.

 

ANALYSIS: 

Note that CHATGPT preceded two of its three answers with the words, “I’m not a doctor, but,” which likely removes the possibility that CHATGPT creator OpenAI will be sued for medical malpractice. From the answers above, I’ll attest that if you’re an inexperienced anesthesiologist or certified registered nurse anesthetist (CRNA) working alone, there is value having a resource like CHATGPT immediately available. Are there any notable errors in the CHATGPT answers? No, not really. As a written reply to the questions posed, the artificial intelligence of CHATGPT gives a reasonable outline regarding how to proceed.

Anesthesia is an acute care specialty, and often there will be no time to consult CHATGPT regarding what to do next because the patient is trying to die right in front of you, for example in the second and third scenarios above. Expect artificial intelligence in medicine to be most applicable in specialties like radiology, pathology, and dermatology, where digital images are analyzed. In radiology, this would be the evaluation of digital X-rays, MRIs, or CT scansIn pathology, this would be the evaluations of digital images of microscopic biopsies, and in dermatology, this would be the evaluation of digital images of skin lesion photographs. The model for the machine learning of digital images will be similar to the process in which a human child learns. When a child sees an animal, 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.

CHATGPT relays information developed by algorithms. Is the practice of medicine destined to be directed by computer algorithms? Yes. We’re already guided by algorithms/cognitive aides such as the decision trees of Advanced Cardiac Life Support (ACLS) or the Stanford Emergency Manual. These flow charts are useful to direct acute care, and to assure no aspect of emergency treatment is overlooked. Expanded use of algorithms is inevitable as more data is accumulated on the management of large populations of medical patients. Current electronic medical records (EMR) systems exist in every hospital, and the EMRs are generating the sort of Big Data that algorithms will be built on.

I’ve had an interest in AI and robots in medicine for years. All Things That Matter Press published my novel Doctor Vita in 2019, several years before CHAPGPT became reality. Doctor Vita described the introduction of artificial intelligence in medicine machines in a Silicon Valley university hospital. A significant and anticipated advance in Doctor Vita is the ability to interact with patients and doctors by voice input and auditory output. In short, the artificial intelligence in medicine of the future will converse with us, just as Alexa and Siri already do.

The World Health Organization projects there will be a shortage of ten million healthcare workers worldwide by the year 2030. Contemplate the following:

  1. All medical knowledge is available on the Internet. Doctors don’t know everything or remember everything, so we routinely look up facts, evidence, and data on the Internet. A computer can recall all of these facts.
  2. Most every medical diagnosis and treatment can eventually be written as a decision tree algorithm;
  3. Voice interaction software is excellent and improving every year;
  4. The physical exam is of less diagnostic importance than scans and lab tests which can be digitalized; and
  5. A computer is far cheaper than the seven-year post-college education required to train a physician.

Will artificial intelligence assist MDs or replace MDs?Replacement of medical personnel with computers will not be welcomed by patients, doctors, or nurses, but there’s a need for cheaper healthcare, and the concept of automating physician tasks is no longer the domain of science fiction. It’s inevitable that AI will change current medical practice. A bold prediction: AI will change medicine more than any development since the invention of anesthesia in 1849.

 

Will the evolution of artificial intelligence in medicine lead to improved healthcare outcomes? In 2018 and 2019 autopilots drove two Boeing 737 Max airplanes to crashes despite the best efforts of human pilots to correct their course. Eleven people were killed in crashes involving vehicles using automated driving systems in the United States during a four-month period in 2022. Will we see improved outcomes or worsening outcomes when AI intersects with medicine, and machines are directing medical care? We don’t know yet. 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, will be the coming of artificial intelligence in medicine.

MY ANESTHESIOLOGIST ADMINISTERED FENTANYL TO ME. IS THAT OK?

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.

INCREASED DOLLAR COSTS ASSOCIATED WITH DIFFICULT INTUBATION

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 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

 

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 RISK OF ANESTHESIA PATIENT TRANSPORT

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.

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.

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.

THE ANESTHESIA CONSULTANT

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
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.

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

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 NEW 2022 ASA DIFFICULT AIRWAY ALGORITHM

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.

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.

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

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.

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.

13 MAJOR CHANGES IN ANESTHESIOLOGY IN THE LAST TEN 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

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.

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.

KIRKUS REVIEW

In this debut thriller, tragedies strike an anesthesiologist as he tries to start a new life with his son.

By the end, Nico has rolled with a great many punches.

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.

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.

THE JULY EFFECT AND THE NOVEMBER EFFECT: In American teaching hospitals, newly minted doctors begin internships each July. The term “July Effect” was coined to describe this shift change in academic hospitals each July, when the arrival of inexperienced doctors may increase the risks of medical care. In the United Kingdom, newly minted doctors begin their internships each August. In Britain, August has been referred to as the “Killing Season,” because of a perceived increased risk of medical complications, morbidity, and mortality with new doctors during their first month on duty.

In American teaching hospitals, newly minted doctors begin internships each July. The term “July Effect” was coined to describe this shift change in academic hospitals each July, when the arrival of inexperienced doctors may increase the risks of medical care. In the United Kingdom, newly minted doctors begin their internships each August. In Britain, August has been referred to as the “Killing Season,” because of a perceived increased risk of medical complications, morbidity, and mortality with new doctors during their first month on duty.

Phillips found medication errors increased 10% during the month of July at American teaching hospitals, but not at neighboring community hospitals (1). In England, an Imperial College London study of records for 300,000 patients at 170 hospitals from 2000 and 2008 found death rates were 6% higher on the first Wednesday in August than on the previous Wednesday (2).

Multiple other studies have shown no change in mortality in American teaching hospitals in July, but the July Effect has real elements. There’s no way the competence of an academic hospital’s physician staff on July 1st can compare with that same hospital’s staff on June 30th. In the specialty of internal medicine, a residency is three years long (the first year of residency is also referred to as an internship). Each July 1st, third-year residents graduate and new medical school graduates replace one-third of the internal medicine team.

Imagine if a corporation like Google, Apple, Facebook, or General Electric dismissed one-third of their workforce once a year. There ‘s no way a company could be as productive after the change.

An anesthesia residency is three years long, preceded by one year of internship. One year after medical school, the same graduate who just completed twelve months of internship now reaches perhaps an even more difficult transition—the first months of anesthesia residency. Instead of writing histories, examining patients, making diagnoses, and prescribing medications as interns and internal medicine doctors do, anesthesia residents are rendering their patients unconscious, applying acute pharmacology, and inserting tubes and needles into patients in operating rooms at all hours of the day and night.

On July 1st of the first day of my anesthesia residency I reported at 0630 hours to the San Jose, California county hospital where I was assigned. I walked into the operating room and stared at the collection of anesthesia apparatus with complete bewilderment. I had no idea how the patient would even be connected to the anesthesia machine. As it turned out, the hoses that exited the machine weren’t installed yet, because I’d arrived before the anesthesia technicians who stocked the operating rooms. When it was time to begin the first anesthetic, the attending faculty anesthesiologist said to me, “I don’t think the operating room is a good place to learn in the beginning.” He injected sodium pentothal into the patient’s IV, placed the breathing tube into the patient’s windpipe, and hooked the patient up to the anesthesia machine. After ten minutes, he left to pursue other duties. I was alone, under-informed, and full of dread. I was on call that same night, and spent twenty-four hours in the hospital enduring case after case until six the next morning. When I left the hospital I had some rudimentary knowledge of how an anesthetic was done, but I’d failed to successfully place a breathing tube into any patient’s windpipe myself—a faculty member had to do every procedure for me. At the conclusion of the last anesthetic, I turned off the isoflurane (the predominant gas anesthetic at the time), switched off the ventilator, and waited, wondering why the patient wasn’t waking up. Many days later I learned that the isoflurane had no way to escape the patient’s lungs or brain unless I kept the ventilator on and continued ventilation of the patient’s lungs.

Anesthesia education today has improved since the 1980’s when I was a first-year resident, but the same themes persist. First-month trainees are very inexperienced. A supervising attending must teach them, mentor them, and lecture them—case by case—until each resident learns the basic skills.

Every month during anesthesia residency, the calendar turns to a new page and a new set of challenges. New rotations include specialty services in obstetrical anesthesia, pediatric anesthesia, trauma anesthesia, cardiac anesthesia, or regional block anesthesia. The most complex cases are saved for the second and third years of residency, but first-year residents will rotate through perhaps 80% of the array of cases during their first twelve months. During the earliest months of training, first-year anesthesia residents gain skills in the basic tasks of placing breathing tubes, intravenous lines, spinal blocks, epidural blocks, and arterial lines. They begin to feel confidence, and the anxiety of July fades.

It’s best if the jitters never fade away completely.

In my fifth year as an anesthesiologist, I was an attending at Stanford University, and I greeted one of my senior colleagues outside the locker room one morning. I asked him how he was doing, and he said, “I’m OK except for the customary pre-anesthesia anxiety.”

“What do you mean?” I said.

“Every morning I have to cope with the reality of what I do. I’m taking patients’ lives into my hands, and I can’t screw up.”

Think about that. Those workers at Google, Apple, Facebook, or General Electric have work pressures, but none of them has anxiety that they could harm a patient’s life forever.

Beyond the July Effect is the “November Effect.” The November Effect is the time when a physician feels confidence—even cockiness—and senses that they are well trained, experienced, in control, and can handle almost anything. The path to the November Effect is circuitous and the timing is variable. When I was an anesthesia resident, several of my colleagues never got there. One colleague succumbed to the stress of late night emergency anesthesia induction. He described to me the ordeal of trying to place a breathing tube urgently into a surgical patient who had a belly full of pizza and beer. I still remember the anesthesiologist’s face as he told the story. His eyes bugged out, his cheeks were pale, and he said, “I underestimated this specialty. I can’t do this for a whole career.” He quit. A second colleague had a near-disaster during the induction of anesthesia for an emergency Cesarean section. His anesthesia machine had no oxygen flow, so he blew into the mother’s breathing tube with his own mouth to keep the patient oxygenated. The patient and her baby survived, but his assessment was, “I can’t do this as a career. I need something less stressful.” He quit, too.

In November of my second year as an anesthesia resident I had 16 months of anesthesia training under my belt. I’d gained the swagger that comes with accomplishment, and lost some of the respect for the dangers of my specialty. I was on call in the hospital for obstetrics one night, and I tried to handle an emergency Cesarean section surgery at 1 a.m. by myself before my anesthesia faculty member arrived to assist me. I’ve chronicled the tale in a previous column (http://theanesthesiaconsultant.com/2012/07/15/an-anesthesia-anecdote-an-inept-anesthesia-provider-can-kill-a-patient-in-less-than-two-minutes). I was unable to place the patient’s breathing tube, she ran out of oxygen, and I thought I’d killed both her and her baby. My attending arrived in the nick of time, entered the operating room donned in his street clothes, and saved the day for all of us.

It was November, not July. I didn’t think I was a novice, but I was. It takes years, maybe a lifetime, to become an expert at anesthesia. Per Malcolm Gladwell’s book Outliers it takes 10,000 hours to become an expert at anything. For the specialty of anesthesia, even if one works 60 hours a week—which translates to about 3000 hours a year—it will take more than three years time to become an expert.

Even after those 10,000 hours, every patient presents a unique opportunity for events to stray from routine. Any case could go awry—there could be an unanticipated allergic reaction, an unexpected surgical bleed, an airway emergency or a mistaken diagnosis. Safe anesthesia practice demands a respectful level of anxiety at all times. Like a Boy Scout, an anesthesiologist needs to be prepared at all times.

Physician overconfidence is a current area of study. Meyer looked at 118 physicians who were each given 4 cases to diagnose (3). Two cases were easy and two were difficult, and the physicians were also asked how confident they were that they’d made the correct diagnosis. The physicians got 55% of the diagnoses correct for the two easier cases, and only 5% of the diagnoses correct for the more difficult cases. On a scale of 0-10, physicians rated their confidence as 7.2 on average for the easier cases, but as 6.4 on average for the more difficult cases. Physicians still had a very high level of confidence, even though their diagnostic accuracy dropped to a mere 5%. This was a striking statistic. Even physicians who are fully trained can be overconfident and can make misdiagnoses. Further data regarding physician overconfidence and how to correct it are welcomed.

An anesthesiologist’s work requires rapid, complex decisions that can be very susceptible to decision errors. Anesthesiologists work in a complex environment in the operating room, a setting where there is little room for mistakes. In acute care medicine, be it in the operating room, the emergency room, a battlefield, or an intensive care unit, the correct management of Airway-Breathing-Circulation is imperative to keep patients alive and well. Errors, be they caused by inexperience or overconfidence, can result in dire complications.

What does this mean for you?

If you’re a patient be wary of inexperienced doctors at a teaching hospital, especially in July and August. You might bring a friend or family member as a patient advocate to assure that more senior and experienced attending physicians are involved in your case. If you’re a patient and dealing with a confident doctor, be aware that confidence is not always well founded. Be skeptical of overconfidence and ask questions.

If you’re an anesthesiologist, look inward and assess whether you’re inexperienced or whether you tend toward overconfidence. Know yourself and better yourself. If you are inexperienced, then gain experience. If you tend to be overconfident, then humble yourself before the practice of medicine humbles you.

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.

ROBOT ANESTHESIA II

THE ANESTHESIA CONSULTANT

Are anesthesiologists on the verge of being replaced by a new robot? In a word, “No.” The new device being discussed is the iControl-RP anesthesia robot.

THE iCONTROL-RP ANESTHESIA ROBOT

On May 15, 2015, the Washington Post published a story titled, “We Are Convinced the Machine Can Do Better Than Human Anesthesiologists.”

In recent years there have been significant advances in the automated delivery of the intravenous anesthetic drugs propofol and remifentanil. (Orliaguet GA, Feasibility of closed-loop titration of propofol and remifentanil guided by the bispectral monitor in pediatric and adolescent patients: a prospective randomized study, Anesthesiology 2015 Apr;122(4):759-67). Propofol is an ultra-short-acting hypnotic drug that causes sleep. Remifentanil is an ultra-short-acting narcotic that relieves pain. Administered together, these drugs induce what is referred to as Total Intravenous Anesthesia, or TIVA. Total Intravenous Anesthesia is a technique anesthesiologists use when they choose to avoid using inhaled gases such as sevoflurane and nitrous oxide. Anesthesiologists administer TIVA by adjusting the flow rates on two separate infusion pumps, one infusion pump containing each drug.

A closed-loop system is a machine that infuses these drugs automatically. These systems include several essential items: The first is a processed electroencephalogram (EEG) such as a bi-spectral monitor (BIS monitor) attached to the patient’s forehead which records a neurologic measure of how asleep the patient is. The 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. The second and third essential items of a closed-loop automated system are two automated infusion pumps containing propofol and remifentanil. A computer controls the infusion rate of a higher or lower amount of these drugs, depending on whether the measured BIS score is higher or lower than the 40- 60 range.

Researchers in Canada have expanded this technology into a device they call the iControl-RP, which is in clinical trials at the University of British Columbia. The iControl-RP is a closed-loop system which makes its own decisions. The initials RP stand for the two drugs being titrated: remifentanil and propofol. In addition to monitoring the patient’s EEG level of consciousness (via a BIS monitor device called NeuroSENSE), this new device monitors traditional vital signs such as blood oxygen levels, heart rate, respiratory rate, and blood pressure, to determine how much anesthesia to deliver.

Per published information on their research protocol, the iControl-RP allows either remifentanil or propofol to be operated in any of three modes: (1) closed-loop control based on feedback from the EEG as measured by the NeuroSENSE; (2) target-controlled infusion (TCI), based on previously-described pharmacokinetic and pharmacodynamic models; and (3) conventional manual infusion, which requires a weight-based dose setting. (Reference: Closed-loop Control of Anesthesia: Controlled Delivery of Remifentanil and Propofol Dates, Status, Enrollment Verified by: Fraser Health, August 2014, First Received: January 15, 2013, Last Updated: March 5, 2015, Phase: N/A, Start Date: February 2013, Overall Status: Recruiting, Estimated Enrollment: 150).

In Phase 1 of the iControl-RP testing involving 50 study subjects, propofol will be administered in closed-loop mode and a remifentanil infusion will be administered based on a target-controlled infusion. In phase 2 involving 100 study subjects, both propofol and remifentanil will be administered in closed-loop mode. The investigators aim to demonstrate that closed-loop control of anesthesia and analgesia based on EEG feedback is clinically feasible.

In both phases, an anesthesiologist will monitor the patient as per routine practice and have the ability to modify the anesthetic or analgesic drugs being administered. That is, he or she will be able to adjust the target depth of hypnosis, adjust the target effect site concentration for remifentanil, immediately switch to manual control of either infusion, administer a bolus dose, or immediately stop the infusion of either drug. iControl-RP is connected to the NeuroSENSE EEG monitor, the two infusion pumps for separately controlled propofol and remifentanil administration, and the operating room patient vital signs monitor. A user interface allows the anesthesiologist to set the target EEG depth level, switch between modes of operation (manual, target-controlled infusion, or closed-loop), and set manual infusion rates or target effect-site concentrations for either drug as required.

Per the article in the Washington Post. (Todd C. Frankel, Washington Post, May 15, 2015), one of the machine’s co-developers Mark Ansermino, MD said, “We are convinced the machine can do better than human anesthesiologists.” The iControl-RP has been used to induce deep sedation in adults and children undergoing general surgery. The device had been used on 250 patients so far.

Why is this robotic device only a small step toward replacing anesthesiologists?

A critical realization is that anesthetizing patients requires far more skill than merely titrating two drug levels. Every patient requires (1) preoperative assessment of all medical problems from the history, physical exam, and laboratory evaluation of each individual patient, so that the anesthesiologist can plan and prescribe the appropriate anesthesia type; (2) placement of an intravenous line through which the TIVA drugs may be administered; (3) mask ventilation of an unconscious patient (in most cases), followed by placement of an airway tube to control the delivery of oxygen and ventilation in and out of the patient’s lungs; (4) observation of all vital monitors during surgery, with the aim of directing the diagnosis and treatment of any complication that occurs as a result of anesthesia or the surgical procedure; (5) removal of the airway tube at the conclusion of most surgeries, and (6) the diagnosis and treatment of any complication in the newly awake patient following the anesthetic.

In the future, closed-loop titration of drugs may lessen an anesthesiologist’s workload and free him or her for other activities. In the distant future, closed-loop titration of drugs may free a solitary anesthesiologist to initiate and monitor multiple anesthetics simultaneously from a control booth via multiple video screens and interface displays. But the handling of all tasks (1) – (6) by an automated robotic device is still the stuff of science fiction. The Washington Post article said an early role for the machine could be in war zones or remote areas where an anesthesiologist is unavailable. One could conjecture that a closed-loop anesthesia system may be used to facilitate surgery in outer space some day as well.

In either case, an anesthesiologist or some other highly-trained medical professional will still be required on site to achieve tasks (1) – (6).

The iControl-RP has not been approved by the U.S. Food and Drug Administration.

The iControl-RP team has struggled to find a corporate backer for its project. Dr. Ansermino, the anesthesiologist inventor in Vancouver, told the Washington Post, “Most big companies view this as too risky,” but he believed a device like this was inevitable. “I think eventually this will happen,” Ansermino told the Washington Post, “whether we like it or not.”

That may be, but I suspect companies are risk averse regarding the iControl-RP because investment is guided by analysts and physicians who must consider the practical applications and risks of any new medical device. The issues of leaving (1) – (6) up to a robotic device are impractical at best, and dangerous to the patient at worse.

BLOOD PRESSURE DROPS TO 85/45 FOLLOWING THE INDUCTION OF ANESTHESIA: WHAT DO YOU DO?

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

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.

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:

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.

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.

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.

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?

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.
emailrjnov@yahoo.com
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.

HOW LONG WILL IT TAKE ME TO WAKE UP FROM GENERAL ANESTHESIA?

emailrjnov@yahoo.com
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 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

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?

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.

SHOULD PHYSICIANS BE TESTED FOR DRUGS AND ALCOHOL?

An 60-year-old man has a heart attack in the middle of an emergency abdominal surgery at 11:00 pm and dies two hours later. Should the anesthesiologist submit to a drug test to seek out alcohol or drug ingestion that could have made her performance impaired?

Discussion: In the 2012 movie Flight, Denzel Washington stars as a commercial airline pilot addicted to alcohol and cocaine, who crashes his airplane while he is intoxicated. Analogies between aviation and anesthesia are commonplace. Both involve takeoffs, landings, and varying cruising times between the two. Both are generally quite safe, but on occasion disastrous accidents occur.

Pilots are required to submit to random drug testing and to testing following accidents. The Federal Aviation Administration (FAA) mandated drug and alcohol testing of safety-sensitive aviation employees in the Omnibus Transportation Employees Testing Act of 1991 to help protect the public and keep the skies safe.

Proposition 46 was a 2014 California legal initiative that proposed similar random drug testing of physicians and drug testing following critical sentinel events. Prop 46 was on the ballot for the November 2014 general election, and was soundly defeated. This proposition was noteworthy for bundling the drug-testing proposal with an additional proposal that would increase the maximum pain and suffering malpractice reward from $250,000 per case to $1,100,000 per case. Prop 46 was funded and supported by trial lawyers who sought to raise the ceiling on pain and suffering awards they could win in medical malpractice suits in California.

This malpractice award increase proposed by trial lawyers was viewed as a money grab, and was unpopular with voters. Because of concerns with increasing malpractice costs and health care costs, Prop 46 was defeated.

But what if Prop 46 had solely been about drug-testing physicians? Would it have a better chance of passing? I have no crystal ball, but my guess is that yes, it would have had a better chance of passing. According to the September 13, 2014 edition of the Los Angeles Times, the component of Prop 46 that required random drug and alcohol testing of doctors was popular among those surveyed: 68% of likely voters were in favor of it, while 25% were opposed.

In the August 1, 2014 issue of the New York Times, Adam Nagourney wrote “At a time when random drug testing is part of the job for pilots, train operators, police officers and firefighters—to name a few—one high-profile line of work has managed to remain exempt: doctors. That may be about to change. California would become the first state to require doctors to submit to random drug and alcohol tests under a measure to appear on the ballot this November. The proposal, which drew approval in early focus groups, was inserted as a sweetener in a broad initiative pushed by trial lawyers that also includes an unrelated measure to raise the state’s financial cap on medical malpractice awards for the first time since 1975, to $1.1 million from $250,000.”

The same New York Times article states, “Backers of Proposition 46 have begun putting out a steady stream of news releases about cases involving doctors with a history of drug and alcohol abuse…. ‘It’s crucial: I can’t believe we haven’t done this already,’ said Arthur L. Caplan, a medical ethicist at New York University. ‘But the idea that we wouldn’t be screening our surgeon, our anesthesiologist or our oncologist when we are going to screen our bus drivers and our airline pilots strikes me as ethically indefensible.’” In the same article, Daniel R. Levinson, the inspector general for the Department of Health and Human Services, opines that there should be random drug testing across the medical profession, given the access in hospitals to controlled substances. “I don’t think that a carve-out when it comes to the medical field is sensible public policy,” he said. “No one should be above suspicion or below suspicion. I think we all need to play by similar rules.”

In a recent commentary published in the Journal of the American Medical Association (JAMA), Dr. Julius Pham of Johns Hopkins wrote, “Patients and their family members have a right to be protected from impaired physicians…. Why is there such a difference among high-risk industries, which all pledge to keep the public safe? First, medicine is underregulated compared with other industries. The fiduciary patient-physician relationship is generally considered to be governed by the profession, not to be tampered with by regulatory bodies. While some state and individual health system regulations exist, they tend to be weak. Second, self-monitoring is the essence of medical professionalism. Peer review is the accepted modality to identify physicians with impaired performance. Most states now have a designated physician health program to detect and assist potentially impaired physicians before those physicians cause patients harm. However, these programs vary in their mandate, authority, reporting requirements, and activities. For instance, California has the largest number of US physicians, but its physician health program was recently discontinued. In states without proactive programs, it seems, by default, that patient harm has to occur before a review process occurs. In many cases, an overwhelming amount of data (i.e., harmed patients) must be available before a hospital or state initiates an investigation.”

Dr. Pham goes on to say, “What might a model of physician impairment regulation look like? First, mandatory physical examination, drug testing, or both may be considered before a medical staff appointment. This already occurs in some hospitals and has been successful in other industries. Second, a program of random alcohol-drug testing could be implemented. Random testing is required for most federal employees and has been successfully implemented in several medical settings. Random testing in the military has resulted in a decrease in illicit drug use. Third, a policy for routine drug-alcohol testing could be initiated for all physicians involved with a sentinel event leading to patient death. Fourth, a national hospital regulatory/accrediting body could establish these standards to maintain consistency across states.”

It’s estimated that approximately 10% to 15% of all healthcare professionals misuse drugs or alcohol at some time during their career. Although rates of substance abuse and dependence are no different than those in the general population, the stakes are higher because healthcare professionals are caregivers responsible for the general health and well-being of our population. It’s known that specialties such as anesthesiology, emergency medicine, and psychiatry have higher rates of drug abuse, possible due to the stress level associated with these specialties, the baseline personalities of these healthcare providers, and easy access to drugs in these specialties.

As physicians, do we have any compelling arguments to deflect the notion of MD’s being drug tested? Physicians decry the intrusion into their privacy. There is the ethical question whether the risk of patient injury by the 10% of physicians who use drugs and/or alcohol merits that the other 90% of physicians should be subjected to drug testing. There is also the specter of false-positive tests, which could wreak havoc with a doctor’s reputation. The details of any proposed drug and alcohol screening programs will be crucial, and any screening program will require careful consideration of a physician’s rights and privacy.

Two prominent hospitals—Massachusetts General Hospital in Boston and the Cleveland Clinic in Ohio—implemented random urine drug testing in their anesthesia residency teaching departments. A 2005 survey by the Cleveland Clinic estimated that 80 percent of anesthesiology residency training programs reported problems with drug-impaired doctors, and an additional 19 percent reported a death from overdose. “The problem is that we are exposed to, and we have the use of, very highly addictive and potent medications,” said Dr. Michael G. Fitzsimons, administrator for the substance abuse program of the department of anesthesia and critical care at Massachusetts General Hospital in Boston. Dr. Gregory B. Collins, section head of the Alcohol and Drug Recovery Center, at the Cleveland Clinic Foundation, said, “The first thing you often realize in these cases, it’s a kid dead in the bathroom with a needle in his arm.” Dr. Arnold Berry, an anesthesiologist and a member of the Committee on Occupational Health of the American Society of Anesthesiologists, said estimates of anesthesiologists who are addicted to medication range from only 1 to 2 percent. “The most recent study in training programs suggests the (addiction) rate has stayed the same for 20 years,” he said. Dr. Berry said the American Society of Anesthesiologists (ASA) has decided to use other tactics to stave off addiction, rather than recommending urine testing. The ASA is implemented a “wellness initiative” to help anesthesiologists deal with stressors in their lives.

While doctors and organized medicine may delay the notion of drug testing for themselves, public opinion and lawmakers may lead the way toward making physicians “pee in the cup.” Citizens don’t want their airline pilots, firemen, and police officers under the influence of alcohol or drugs, and patients don’t want their doctors under the influence of alcohol or drugs either.

Our patients always come first. It will be an arduous task for MD’s to forever oppose a mandate for clean and sober physicians. Hugh Laurie was a fascinating character as the opiate-popping junkie doctor in “House,” but what patient wants the TV persona of Dr. Gregory House at their bedside?

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.

DO YOU NEED AN ANESTHESIOLOGIST FOR ENDOSCOPY OF YOUR ESOPHAGUS, STOMACH, AND UPPER GASTROENTEROLOGIC TRACT?

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 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.

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.

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.

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.
emailrjnov@yahoo.com
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

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).

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.

OBAMACARE 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

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.

HOW DOES A HEROIN OVERDOSE KILL? AN ANESTHESIOLOGIST’S VIEW

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.

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.

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.

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.

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

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.

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 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?

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.

Good luck!

USEFUL PEDIATRIC ANESTHESIA EQUATIONS

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 are driving to the hospital, en route to doing a pediatric anesthetic on a 2-year-old that will require an endotracheal tube. You are thinking through the case in advance. What can you do to plan your anesthetic? There are some useful pediatric anesthesia equations you can use to prepare yourself.

 

intubated anesthetized child

 

During my anesthesia training at Stanford, Dr. Stanley Samuels, the co-author of Anesthesiologist’s Manual of Surgical Procedures, by Jaffe and Samuels, (Fourth Edition, 2009, Lippincott Williams and Wilkins), taught me a series of equations regarding pediatric anesthetics. These equations are listed below, and provide time-tested guidelines to help the anesthesiologist select the correct endotracheal tube size, the correct intravenous infusion rate, and to estimate a child’s weight and dosing requirements of intravenous drugs.

As Dr. Samuels told me, “You can be driving in toward the hospital, knowing that your patient is 2 years old, and plan details of  your anesthetic in advance.” The equations are as follows:

  • The endotracheal tube size = age/4 + 4
  • Estimating a child’s weight:

Newborn = 3 kg

1-year-old = 10 kg

Add 2 kg per year up until the age of 6 years.

  • The IV rate per hour = 40 ml/hr (first 10 kg) + 20 ml/hr (second 10 kg) plus 10 ml/hr for every extra 10 kg
  • Dosing of IV medications:

A 7-year-old takes ½ of adult dose

A 1-year-old takes ¼ of adult dose

A newborn takes 1/10 of adult dose

For your 2-year-old patient, you will prepare a 4.5 ID endotracheal tube, expect the patient to weigh about 12 kilograms, plan a maintenance IV rate of 45 ml/hour, and expect that all drug doses (including emergency resuscitation drug doses) will be in a range of slightly more than ¼ of typical adult doses.

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.

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.

KEEPING ANESTHESIA SIMPLE: THE KISS PRINCIPLE

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

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.

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

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.

WILL YOU HAVE AN ANESTHESIOLOGIST FOR YOUR WISDOM TEETH EXTRACTION SURGERY?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

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.

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.

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

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.

THE OBESE PATIENT AND ANESTHESIA

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.

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.

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.

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

Our anesthesia group routinely performs 8-hour outpatient pediatric anesthetics for combined atresia-microtia ear reconstruction surgeries. As of 2021, we are the only surgical/anesthetic practice in the world performing this surgery in high volume, and we are proud to have restored hearing and a cosmetic ear to hundreds of children from North America, Asia, Europe, Australia, and South America.

 SUCCESSFUL EIGHT-HOUR OUTPATIENT PEDIATRIC GENERAL ANESTHETICS FOR EAR COMBINED ATRESIA-MICROTIA RECONSTRUCTION

Introduction

The surgical team of Joseph Roberson, M.D. and John Reinisch, M.D. regularly performs Combined Atresia-Microtia (CAM) ear reconstruction surgery on children born without normal ear anatomy.  The total anesthetic time for these surgeries regularly totals 7-8 hours.  These children, who are generally in good health other than their undeveloped ear, are observed in the recovery room for 1 – 1 ½ hours, and are then discharged home with their parents.  As of 2021, the total number of CAM reconstructions have totaled over 350 cases.  Surgeries are performed at the California Ear Institute in East Palo Alto, CA, and Waverley Surgery Center in Palo Alto, CA.  The text below describes a the anesthetic care for a typical CAM reconstruction.

Case Report

A 5-year-old male was with congenital atresia and microtia of the left ear was scheduled for combined atresia repair and microtia reconstruction under general anesthesia. The estimated duration of the surgery was 9 hours, and the case was scheduled as outpatient surgery with no overnight stay planned.  The child was healthy.  A previous general anesthetic for adenoidectomy at the age of 2 was unremarkable.  The child weighed 17 kg, and the physical exam was normal except for the deformed ear.  One anesthesiologist administered the anesthetic care.

Premedication was oral midazolam 0.75 mg/kg.  The well-sedated child was brought into the operating room 20 minutes later.  Standard non-invasive monitors were applied, and a mask induction with 8% inspired sevoflurane was carried out.  A 20-gauge IV was inserted into the left arm, and the trachea was intubated.   Maintenance anesthesia was sevoflurane 1 – 1.5% end-tidal, nitrous oxide 50%, propofol infusion at 25 – 50 mcg/kg/min, and incremental doses of fentanyl as needed. Prophylactic antiemetics included ondansetron 2 mg, dexamethasone 4 mg,  and metoclopramide 4 mg.

The operating room table was turned 180 degrees, the circulating nurse inserted a Foley catheter, and a Bair Hugger warming blanket was applied to the patient’s torso.

The surgical procedure was carried out by the otologist and plastic surgeon as previously described (1).   Local anesthesia of bupivicaine 0.5% with 1/200,000 epinephrine was injected into the scalp and ear by the surgeons as indicated.  The surgical procedure was  combined atresia repair of the middle ear, reconstruction of the external auditory canal, and Medpor microtia reconstruction of an external ear.  Total surgical time was 8 ½ hours.

A total of 160 mcg of fentanyl was administered.  Total fluids for the case were 1000 ml of Lactated Ringers intravenously, and the estimated blood loss was 20 ml.  Vital signs were stable throughout, and there was minimal physiologic perturbation. Esophageal temperature was maintained as normal.

In addition to two surgical attendings and one anesthesiologist, staffing included two R.N.’s and one scrub tech.  The surgery concluded and the surgical dressing was applied 7 ½ hours after the induction of general anesthesia.  The Foley catheter was removed.  The anesthetics were discontinued, and the trachea was extubated when the patient opened his eyes.  Post-operative pain was treated by incremental 5 mcg doses of intravenous fentanyl until the patient was comfortable and calm, and the patient was transferred to the recovery room.  The parents were allowed into the recovery room 15 minutes after extubation.  The patient was discharged from the facility 70 minutes after extubation.  At the time of discharge, the patient was alert, pain-free, nausea-free, and tolerating oral fluids, and his Aldrete Score was 9.

Discussion

This combined atresia and microtia repair, requiring a total anesthetic time approaching ten hours, is a new procedure being carried out by our surgical team.   The atresia surgery involves a post-auricular incision, drilling through the mastoid to access the middle ear, and ossiculoplasty, tympanoplasty, creation and skin grafting of an external auditory canal as necessary to reconstruct the atresia.  The microtia repair involves the implantation of the Medpor synthetic auricular prosthesis, and covering the prosthesis with skin grafts obtained from the patient’s abdomen. The surgical-anesthetic team to date has successfully performed the combined procedure on 55 patients, 90% of who were of the ages between 2 and 5 years old.  All patients are ASA I – II, without significant medical comorbidity.  Every procedure to date has been performed as an outpatient.  Patients are discharged when their post-anesthesia care unit Aldrete Score reaches 8/10, and the family and physicians agree that the patient was stable to leave the facility. The discharge times vary between 70 – 100 minutes post-extubation for the 55 patients in our series, with a mean time of 91 minutes.  Post-operative pain is well-controlled by the bupivicaine injected into the operative sites, and because of the minimal post-operative pain, it has been possible to discharge the patients home despite the very long duration of their endotracheal anesthetic.

None of the combined surgeries were performed in a hospital.  The first 20 patients were operated on at a freestanding surgery center, 2 miles distant from the nearest hospital.  The majority of the following 330 patients had their surgery in an operating room in the surgeon’s California Ear Institute office. To date there have been no complications from the anesthetic management, and no admissions to a hospital or an emergency room following the combined procedures.

This case, one of 350+ in a series of similar cases, is noteworthy in that it markedly expands the boundaries of what is possible to safely accomplish with pediatric outpatient general anesthesia performed in a freestanding surgery center or in a surgeon’s office.

Outpatient pediatric surgery is increasingly common.  In 2006, an estimated 2.3 million ambulatory anesthetics were provided in the United States to children younger than 15 years.  Only 14,200 of these 2.3 million pediatric ambulatory anesthetics patients were admitted to the hospital postoperatively, a rate of 6 per 1000 ambulatory anesthesia episodes.  In 1996, 26 per 1000 children under the age of 15 experienced ambulatory pediatric surgery, while in 2006 that statistic increased to 38 per 1000 children.

Parents are often more satisfied with outpatient surgery over post-operative hospitalization. (3) The advantages of outpatient surgery are significant: reduced costs, lower rate of infection, avoidance of hospitalization with the inherent psychological stress, and timely return of the patients to their familiar home environment. (4)

This case report is evidence that pediatric patients can be discharged safely following a prolonged outpatient anesthetic.  Our current experience with such CAM reconstructions, exceeding 350 such cases without serious complication or adverse outcome, demonstrates that this combined procedure can be successfully carried out as an outpatient.  The duration of an anesthetic is not in itself an indication for overnight hospitalization post-operatively.  As well, selected pediatric ambulatory anesthetics of long duration can be safely performed in well-staffed operating rooms in a surgeon’s office, in addition to using a freestanding surgery center..

IS ANESTHESIA 99% BOREDOM AND 1% PANIC?

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.

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.

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 YOU NEED AN ANESTHESIOLOGIST FOR A COLONOSCOPY?

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.

PEDIATRIC ANESTHESIA: WHO IS ANESTHETIZING YOUR CHILD?

Physician anesthesiologist at Stanford at Associated Anesthesiologists Medical Group

THE ANESTHESIA CONSULTANT

Your 4-year-old son Jake is scheduled for a tonsillectomy next Friday morning.  Who will do Jake’s anesthesia, and how will the anesthesia care be done?

Jake may or may not be diagnosed with Obstructive Sleep Apnea (OSA), based on his history of snoring.  Most children who snore and have enlarged tonsils are not subjected to a formal sleep study.  In a formal sleep study, doctors attach monitors such as pulse oximeters and apnea monitors to the child during a night’s sleep, to determine how often the child stops breathing during sleep and how low the oxygen level in his or her arterial blood drops during disordered sleep.  A sleep study is commonly done for adults with suspected OSA, but  not commonly ordered in children.

The decision to excise tonsils in pediatric patients is a clinical decision, based on the judgment of the pediatrician and ENT surgeon.  The surgery can be scheduled at a community hospital, a university hospital, a pediatric hospital, an ambulatory surgery center, or a freestanding ambulatory surgery center.  The nature of the anesthesia personnel can vary significantly depending on which type of facility the surgery is scheduled at.

In a community hospital, the anesthesia staff will be medical doctors (anesthesiologists), and/or nurse anesthetists (CRNA’s).  The anesthesiologists may or may not be pediatric specialists, but all anesthesiologists receive training in anesthetizing children.  Most likely, the ENT surgeon operates with an anesthesia team he or she is comfortable with, and this anesthesia team is comfortable anesthetizing children for a routine, elective surgery like tonsillectomy.  At a community hospital, it is possible but unlikely that the anesthesiologist will have completed extra years of training in pediatric anesthesia called a pediatric anesthesia fellowship.

In a university hospital, the anesthesia staff will include anesthesiologist faculty and also anesthesiologist residents and fellows who are in training.  The anesthesia care is directed or performed by a faculty member.  The actual hands-on anesthesia care, such as the placement of breathing tubes and IV catheters, is usually done by the residents and fellows, who are in the midst of their training.  An advantage of university hospitals is that pediatric anesthesia specialists are plentiful.  A disadvantage is that the anesthesia care is usually done by the trainee anesthesiologists who are supervised by these specialists.  At times, one faculty anesthesiologist may be supervising trainee anesthesiologists in two separate operating rooms for two separate surgeries concurrently.

In a pediatric hospital, the anesthesia care will be done by specialty pediatric anesthesiologists.  However, if the pediatric hospital is a university pediatric hospital, all the analysis in the preceding paragraph pertaining to university hospitals will apply.

An ambulatory surgery center (ASC) is a set of surgical suites that is designed to take care of outpatient surgeries, and designed to send the patient home directly from the ASC after recovery from surgery and anesthesia.  Most tonsillectomies are done as outpatient surgeries, and therefore many tonsillectomy patients are operated on in an ASC.  If the ASC is located inside a hospital, the anesthesia care will follow the analysis of community, university, and pediatric hospitals as discussed in the paragraphs above.  Many ASC’s are freestanding–that is, they are not on site in a hospital.  Many are located miles away from hospitals.  It is commonplace in the United States for tonsillectomies to be safely done in freestanding ASC’s.  The anesthesia care in most freestanding ASC’s will be anesthesiologists and/or nurse anesthetists, and once again the ENT surgeon will select an anesthesia provider he or she feels will provide safe care for his patient.

Some anesthesia teams prefer to meet and interview their patients days before surgery.  For a routine surgery such as tonsillectomy, it is common for the family to not meet the anesthesiologist until the day of surgery shortly before the procedure.  Some anesthesiologists will telephone the parent(s) the night before surgery to interview them and provide a preview of what to expect on the day of surgery.

The actual anesthesia care will typically follow this scenario:  Most practitioners will premedicate the child with oral midazolam (Versed) 20 minutes before the surgery.  This medication will make the child sleepy and relaxed, and calm the patient through the time when they separate from their parent(s).  Most facilities in the United States will not allow parents into the operating room.  Inside the operating room, the anesthesiologist will apply standard monitors of oxygen level, pulse, and blood pressure, and induce anesthesia by having the child breath the anesthesia gas sevoflurane through a mask.  Once the child is asleep, the anesthesiologist will place an IV in the child’s arm and a breathing tube in the child’s airway.  After the surgery is completed, the anesthesiologist will discontinue the anesthetics, awaken the child, and remove the breathing tube.  He or she will accompany the child to the Post Anesthesia Care Unit (PACU) and turn over the care of the child to a nurse there.

Is it safer if your child has a pediatric anesthesiologist, rather than a general practitioner anesthesiologist who takes care of both adults and children?  It depends.  It’s important to ask how often the practitioner anesthetizes children.  Someone who rarely anesthetizes a child under 6 years of age will be less comfortable with such a case, and may be less skillful in dealing with a complication or emergency should one occur.

Is it safer if your child has a fully-trained anesthesiologist rather than an anesthesia trainee/faculty team such as at a university hospital program?  Once again, it depends.  It depends on how much of the care is done by the trainee, and how intensive the faculty supervision is, as compared to an alternative facility where a fully-trained anesthesiologist stays present throughout the entire surgery.

At a community hospital or ASC, it is uncommon to have multiple specialist anesthesiologists on call each day, e.g. one for pediatrics, one for cardiac cases, one for trauma, one for obstetrics, and others for the general operating rooms.  Instead, general anesthesia practitioners cover many or all specialties.  If an anesthesiologist is not comfortable with an individual case, they can seek out a better trained anesthesiologist to cover the case, if such an anesthesiologist is available.  The trend for having a specialist anesthesiologist for every type of case is a difficult one to staff.  The goal at a community hospital is to assure that the standard of anesthesia care can be met with the physicians who are on staff and available.

In my opinion, neonates and  young infants should be cared for by  anesthesiologists with specialized pediatric training.  Whether specialized training should be mandated for children older than infants is debatable.  Policies to define a minimum age limit for patients of general anesthesiologists may be a hot topic in the future.

In the meantime, I recommend you ask your child’s anesthetist:  1) who is doing the actual anesthesia care today, a fully-trained anesthesia doctor, a doctor-in-training, or a nurse anesthetist?  2) how much training does the anesthetist have with children Jake’s age? and 3) how many children of Jake’s age have they anesthetized for a similar surgery in the past 12 months?  If you are uncomfortable with any of the answers, find another place for Jake to have his 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.

A PREOPERATIVE ANESTHESIA CLINIC: DO YOU NEED ONE?

THE ANESTHESIA CONSULTANT

Do you need a Preoperative Anesthesia Clinic? You’ve just graduated from your anesthesia training program.  The night before your first day in community practice, your operating room surgery list reads: 7:30 a.m. = 68-year-old male for a thyroidectomy, 11 a.m. = 42-year-old male for laparoscopic cholecystectomy, and 1 p.m. = 56-year-old female for a vaginal hysterectomy.

Who, if anyone, has done the preoperative evaluations for these patients?  How can anesthesiologists and surgeons function without a preoperative clinic and its employees to evaluate patients prior to surgery?

Discussion:  In the academic teaching setting, the Preoperative Anesthesia Clinic is useful.  University surgical patients are complex, not all residents in anesthesia and surgery are experienced in preoperative evaluation, and many patients do not have an internist or a primary care provider.

In most community practice models, a Preoperative Anesthesia Clinic is impractical.  As community anesthesiologists in private practice, we distribute guidelines to surgeon’s offices regarding the indications for preoperative lab tests, consultations, and medication management.  Surgeons or their nurse practitioners do the preoperative evaluations for healthy patients, and surgeons refer more complex patients to internists preoperatively as indicated.  When the surgeon wants an anesthesia consult (or else risk a cancellation on the day of surgery), he or she will call the attending anesthesiologist who is responsible for preoperative phone consultations.  The surgeon or the surgeon’s nurse practitioner will present the case, and the anesthesiologist will advise whether further diagnostic tests or medicine consultations are necessary prior to scheduling the surgery.

The night before the surgery, each attending anesthesiologist in our practice usually telephones their patients.  The anesthesiologist asks medical history questions that are pertinent, and answers the patient’s questions.  Patients are advised as to eating and drinking restrictions before surgery, and whether the patient should take or hold any usual oral medications in the day prior to surgery.

On the day of surgery, pertinent labs, ECG’s and consults are on the chart.  Any omissions can be supplemented, e.g. bedside ECG or fingerstick blood glucose.

This method works in community private practice of anesthesia, because all the involved M.D.’s are fully trained and they have incentive to complete the surgical cases, not to cancel them.  Key advantages of this method are

(1) Patients like it.  Patients like talking to their attending anesthesiologist the night before, instead of waiting at an anesthesia clinic to be evaluated by a third party.

(2 ) There is no expense to rent clinic space and pay clinic employees.

(3) Community private practice anesthesiologists do not want to staff a clinic, where there is no financial incentive to be there.

(4) For pediatric surgery, parents prefer to talk to the attending surgeon the night before surgery from the comfort of their own home, rather than bringing their child to the hospital twice.

(5) This system works.  Our practice averages averages 1-2 cancellations on the day of surgery per anesthesiologist per year.  Example cancellations may occur for patients who have fever the day of surgery, chest symptoms the day of surgery, or elevated blood pressure the day of surgery.  Very few patients are cancelled because of incomplete laboratory workup, as current anesthesia standards show that many preoperative lab tests are either not indicated or do not change the management of the anesthetic. See the American Society of Anesthesiologists (ASA) Practice Advisory for Preanesthesia Evaluation.

Instead of staffing a Preoperative Anesthesia Clinic, your preoperative homework is three telephone calls the night before surgery.  Because it is your first day at a new practice, you choose to telephone a senior member of your anesthesia group the night before surgery as well, so he or she can give you advice on what to expect from each surgeon the next day.  Time = 25 minutes.  Cost = 0.

An occasional patient may need to be evaluated prior to the day of surgery. The American Society of Anesthesiologists (ASA) Practice Advisory for Preanesthesia Evaluation addresses the issue of the timing of preanesthesia evaluation. For cases of high surgical invasiveness, 59% of ASA members recommended that the preoperative anesthesia history and physical take place prior to the day of surgery.

For patients with a high severity of disease, 89% of ASA members recommended that that the preoperative anesthesia history and physical take place prior to the day of surgery.

In these instances, arrangements can be made for a member of the anesthesia group to meet and evaluate the patient prior to the day of surgery.

ANESTHESIOLOGISTS GET NERVOUS, TOO

Clinical Case for Discussion:  Anesthesiologists have anxiety at times. Let’s say you are an attending anesthesiologist in private practice, in your first year out of residency.  Your schedule for the next morning includes a 60-year-old, 350-pound male with ankylosing spondylitis and congestive cardiomyopathy for cholecystectomy.  You turn off the lights the night before at 10 p.m., and cannot fall asleep, as you are worried about the case.  What do you do?

Discussion:  During my first year in private practice, one of my senior anesthesia colleagues, ripe with gray hair and receding hairline, stood outside of his operating room at 7 a.m.  I bid him good morning and he said, “It is a good morning, despite the usual anxieties that come with what I’m about to do.”  I asked him to explain, and he said, “Every day I come to work knowing that something could go wrong, and my patient could be harmed, and it could change my life forever.  That gives me anxiety, which I have to cope with every day.”

Anesthesia textbooks are thick with information on how to assess patients preoperatively, how to perform anesthetics, and how to manage postoperative medical problems.  You won’t find much guidance on how to handle your own anxieties as an anesthesia provider.

What are chances that you will have a perioperative death during your career in anesthesia?  In a recent published survey, 84% of anesthesiologist respondents had an unexpected perioperative death or serious injury of a perioperative patient during their career. A majority of these respondents indicated that they experienced guilt, depression, anxiety, sleeplessness, fear of litigation, fear of judgment by colleagues, anger, and reliving of the event. Five percent experienced use of drugs or alcohol and 12% considered a career change after the event.

During my 32-year career as an attending anesthesiologist in private practice, I’ve had two unanticipated patient deaths.  Both events had me reeling for some time.  The first was a male in his 70s for an open abdominal aortic aneurysm repair.  The case occurred at a local community hospital, six months after completing my Stanford training.  As the vascular surgeon closed the abdominal incision, the patient went into pulmonary edema, dropped his cardiac output and arrested.  The resulting unsuccessful CPR, followed by the conversations with the surgeon and the patient’s family, were gut-wrenching experiences.  Because I was new at the hospital, I’m sure there were individuals who doubted my abilities and competence.  The post-mortem diagnosis was myocardial infarction.  The case went through peer review, my management was not challenged, and no one blamed the anesthesiologist.  But I remember that one day after this patient died, my first patient was a sickly 90-year-old.  If my hands weren’t shaking that morning, my confidence was.

The second death was an elderly insulin-dependent diabetic end-stage-renal-disease patient who was having an upper extremity arterial-venous fistula revision for dialysis access.  At the conclusion of the case, I administered protamine to reverse the heparin, and the patient’s oximeter stopped beeping.  Her automated blood pressure cuff readings became unobtainable.  It took me several moments to figure out that she had no discernible pulse either.  Her only working monitor was the sinus rhythm on the ECG, and that soon deteriorated into ventricular fibrillation.  We could not resuscitate her. The post-mortem assessment was anaphylaxis to protamine.  This case occurred in the third year of my private practice career, and again it shook my confidence for a while.

Anesthesia practice can be lonely.  During university training, each anesthesia resident has an attending to back them up and emotionally hold their hand through both easy and difficult cases.  When you finish training and enter the next phase of your career, you have to work alone.  In the middle of the night, you may be presented with an extraordinarily sick patient and you may be the only anesthesiologist for miles around.  In some practices you will work in freestanding facilities, and again you will be the only anesthesiologist for miles around.

What about the Clinical Case above, where you are the first-year attending anesthesiologist who can’t sleep because you’re worried about the difficult airway, the morbid obesity, and the congestive cardiomyopathy in your patient for the next day?  What are solutions to the anxieties an anesthesiologist experiences?  I’m no psychiatrist, but here’s my advice after having toiled in the anesthesia arena for 25 years:

1) You’re often going to feel anxious, and that’s normal.  Expect it.

2) Learn as much as you can during your residency, so you emerge from your training with confidence.  Not cockiness–“Man’s got to know his limitations,” as Dirty Harry famously said in Magnum Force–but you need to be confident.

3) If you’re truly worried or in over your head, remember how reassuring it was in residency to have an ally. Call another attending the night before for their opinion on a difficult case for the next day. Call for help before you start a challenging case regarding a difficult intubation or a complex anesthetic induction.

4) Cultivate a strong emotional support team of people, inside and outside of the hospital.  You’ll need them.

4) If you run into ongoing insomnia, depression, or fear, seek professional help.  It’s well known that anesthesiologists are vulnerable to chemical dependence.  Treating your own insomnia or anxiety with fentanyl or Versed or propofol will be a dead end.

The same anesthesia attending I referred to in the first paragraph once told me, “There are three ways an anesthesiologist can end his career.  He can: 1) die in mid-career, 2) quit because he can’t handle the stresses of the job any more, or 3) walk away and retire on their own terms when they choose to.”

Let’s hope each of us gets to choice number 3!

ANAPHYLACTIC REACTION UNDER GENERAL ANESTHESIA

THE ANESTHESIA CONSULTANT

Clinical Case For Discussion:    Anaphylaxis during anesthesia can be a difficult diagnosis. A 59-year-old male is undergoing a sigmoid colectomy.  Twenty minutes after surgery begins, the peak inspiratory pressure on the ventilator  rises to 50 cm H2O, and the systolic blood pressure reading on your vital signs monitor drops to 70.  What do you do?

 

Discussion:     You begin by rechecking the ABC’s of Airway, Breathing, and Circulation.   You suction the  endotracheal tube to be sure it is patent.  It is.  You squeeze the bag and listen to the lungs to make sure both lungs are ventilated.  They are, but there are diffuse wheezes.  You recheck the blood pressure device in the stat mode.  The repeat blood pressure is unchanged.  You feel for peripheral pulses, and they are not palpable.  Heart tones are present, but the rate is 140 beats per minute.  The oxygen saturation is 70%.  There are no acute ST changes on the ECG.  The exposed skin is normal.

You need a diagnosis to make the appropriate therapy.  This is the acute onset of a multi-system disorder, with bronchospasm and hypotension, in a previously healthy patient.  There are not many conditions that cause both acutely, and I want you to think of anaphylaxis early on.  A differential diagnosis includes:

(1)  an acute myocardial infarction, with left heart failure and pulmonary edema,

(2) acute septic shock, or

(3)  airway occlusion or acute asthma with decreased ventilation and cardiac dysfunction.

The absence of ST changes, arrhythmias, rales, or gallop make the first unlikely,  the second is very uncommon, and respiratory dysfunction is not likely to cause hypotension.

At the beginning of any surgery, multiple drugs including anesthetics, muscle relaxants, narcotics, and antibiotics are given in a short time period.  The identity of which drug is causing the allergic reaction is often impossible to determine.   Anaphylaxis secondary to latex exposure from  surgeon’s gloves has also been reported.

Regardless of the cause of the anaphylaxis, the treatment will be the same.

Anesthetic drugs are stopped, 100% oxygen is administered, and a bolus of intravenous fluid is given.   Treatment must include intravenous epinephrine.  Other causes of hypotension can be treated with  dopamine or phenylephrine, but anaphylaxis will not respond to these drugs.   Bronchospasm can be treated with  inhaled bronchodilators such as albuterol, but this  will have little effect in anaphylaxis.

Prompt epinephrine therapy is crucial.  The dose of epinephrine is important.  The 1 mg.  ampule of epinephrine needs to be diluted.  Treatment  is begun in 10 to 100 microgram increments,  and increased as needed.    The response should be immediate, with increase in systemic vascular resistance, blood pressure, and improvement in bronchospasm and oxygen saturation.  An epinephrine infusion may be needed to maintain vital signs.  An arterial line and central venous catheter are inserted.  Adjunct drugs such as steroids, diphenhydramine, and an H-2 blocker are given intraveously.

The surgery is quickly ended.  The patient is transferred to the ICU, with the trachea still intubated.

An excellent textbook reference on the treatment of anaphylaxis is the Stanford Cognitive Aid Emergency Manual, available for free download on the Internet.

In 27 years of anesthesia, I have had 4 cases of anaphylaxis.  In these 4 episodes the offending drugs were  (1) protamine,  (2) intravenous contrast dye, (3) vecuronium, and (4) atracurium.

If you were to ask graduating anesthesia residents what is likely to be the case of their career, most would probably say some big heart/thoracic/neuro/zebra type of case.  This case shows that it may be some typical case, where something bad happened when they were least expecting it.

MANAGEMENT OF STROKE IMMEDIATELY FOLLOWING CAROTID ARTERY SURGERY

THE ANESTHESIA CONSULTANT

Clinical Case for Discussion:  A 74-year-old man is scheduled for a left carotid endarterectomy.  At the conclusion of the anesthetic, his blood pressure rises to a Mean Arterial Pressure (MAP) of 110, and he is unable to move the right side of his body.  What do you do?

 

Discussion:   In 19 years of doing vascular anesthesia, I  had this happen to my patient two times.   The first time it occurred, I wasn’t sure what to do, if anything, about the new neurologic deficits.

Let us assume that you already carried out the textbook approach to  anesthesia for carotid thromboendarterectomy (TEA) for this patient.   All appropriate diagnostic and therapeutic measures were done to prepare the patient for surgery.   His preoperative MAP was 100.  During the general anesthetic the MAP was maintained between  90 and 110.   The surgeon used a carotid shunt, and during clamping and shunting no hypotension occurred.  (These were the circumstances  in both the post operative strokes in my patients.)   At the conclusion of surgery, you discontinued the anesthetics, and the  blood pressure increased as the anesthetic depth lightened.  The MAP increased to 110.  You extubated the patient awake.  Then you noticed that the right leg and arm were not moving.  The surgeon returned to the bedside, and said, “I need him back asleep, as fast as possible!”

What do you do at this point?   You give additional doses of anesthetic and relaxant, and reintubate the trachea.  You may be feeling guilty, wondering if this paralysis is an anesthetic complication.    What the surgeon is thinking is, “do I have a diagnosis that I can treat, such as a dissection, a flap, or a clotted  carotid artery?”  The surgeon may ask you to give a repeat dose of heparin to the patient.  After a quick prep and drape, he  reopens the  skin incision.   The surgeon assesses the pulse in the carotid, and may do a Doppler ultrasound exam.  Next is an on-the-table angiogram, which shows that both the common and internal carotid arteries are 100% occluded.

The surgeon closes the wound.  You discuss the plan with the surgeon.  The plan is to  keep the trachea intubated to protect the airway.  You discontinue the general anesthesia, and substitute a propofol infusion for  transport to the ICU.

Per Miller’s Anesthesia, 5th edition, 2000, p 1878, “for carotid endarterectomy, most centers report a perioperative stroke rate of between 3 and 5 per cent.  The incidence of perioperative stroke is highest for patients with stroke, lower for patients with transient ischemic attack, and lowest in asymptomatic patients.  Neurologic deficits occur most commonly in patients with poorly controlled preoperative hypertension or in those with hypertension or hypotension postoperatively.  More than half of these deficits occur more than 4 hours postoperatively.”

If you do hundreds of carotid TEA’s during your career,  a non-zero number of patients will have postoperative strokes.  As the anesthesiologist, you have control of the patient’s blood pressure and heart rate.   Extremes of blood pressure that are outside the range of autoregulation of cerebral perfusion can contribute to cerebral ischemia.   But most strokes will be surgical complications.   Per Sabiston,  (Textbook of Surgery, 2001, p 1348), “neurologic deficits within  the first 12 hours of operation are almost always the result of thromboembolic phenomena stemming from the endarterectomy site or damaged internal, common, or external carotid arteries.”

I learned from my experiences not to extubate the carotid TEA patient until he proves he is awake and can move the contralateral extremities.  If there is a stroke, you need only to give more drugs to resume anesthesia, instead of the risks of repeat laryngoscopy and intubation as in the case above.

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.

PEDIATRIC ANESTHESIA: DO YOU NEED A SPECIALIST PEDIATRIC ANESTHESIOLOGIST TO ANESTHETIZE CHILDREN?

THE ANESTHESIA CONSULTANT

Clinical Case for Discussion: 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  an open eye injury, and is taken to the nearest hospital.  You are on call for the  repair.  You are an experienced practitioner, but not a pediatric anesthesia specialist.  What do you do?

Discussion:  There are two issues.  One is how to do the open-eye, full stomach anesthetic, and the other is 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).   The list of things which increase IOP, and risk further eye damage, includes crying, coughing,  the Valsalva manuver, laryngoscopy, and endotracheal intubation.   Ketamine and succinylcholine may also increase IOP.   Trying to start an IV without causing crying in a 3 year old can be  difficult.

No single approach to this patient is ideal, but a proposed approach to this patient is:   (1)  Apply EMLA cream, with occlusive dressing, over several potential IV sites 45 – 60 minutes before the IV attempt.  Next, give the child an oral midazolam premedication (.75 mg/kg), and wait until he becomes sedated enough to start the IV.

(2)  Once the IV is in place, a modified rapid sequence induction is done with cricoid pressure, using  rocuronium  as the muscle relaxant.  Either a priming dose of the relaxant, or a dosage of 2 X the normal intubating dose is used to speed the pace of neuromuscular blockade.  A nerve stimulator is used to  confirm that depth of muscle blockade is adequate, to avoid 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 (4 – 6 minute) increase in IOP of 10 to 20 mm Hg, although there have been no clinical case reports of further eye damage or other complications in open eye surgery following succinylcholine.  (Miller, Anesthesia, 2000, 2176-79).

(3)  If the child is chubby, and you are not able to place the IV despite adequate oral sedation, you may proceed with an inhalation induction 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)  At the conclusion of surgery, the patient is extubated awake.  The approach to this type of patient is well summarized in Gregory, Pediatric Anesthesia, 1994, p 683.

The second issue in this case is that you are not a pediatric anesthesiologist.   Los Angeles Times  articles on February 24,  and March 6, 2003, described  an infant death and a near-death at a Southern California Kaiser hospital, when pediatric anesthesia care was given by a general anesthesiologist.  This Kaiser hospital has adopted  an interim policy to  limit anesthesia care for patients under the age of  2 years to anesthesiologists with specialized pediatric training.

At Stanford University Medical Center and Packard Children’s Hospital, the University service has a team of pediatric anesthesiologists with specialized training who attend to each pediatric anesthetic.  When private or University attendings reapply for medical staff privileges at Stanford every 2 years, we are required to tally the number of children we have anesthetized in the following age groups:  (a) newborn to 6 months,  and (b)  6 months to 6 years.  A minimum number of cases is needed to maintain privileges.

Things are different at a community hospital, where a  smaller team of anesthesiologists shares night call.  Unless the hospital is very large, it is uncommon to have multiple specialist anesthesiologists on call each day, e.g. one for pediatrics, one for cardiac cases, one for trauma, one for obstetrics, and one for the general OR.  It is common for general anesthesia practitioners to cover many or all specialties when they are on call.  If they are not comfortable with an individual case, they can seek out a better trained anesthesiologist, if one is available.  The trend for having 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 a patient at  a community hospital is a judgment as to whether standards of care can be met with the physicians who are available.

In my opinion, neonates and  young infants should be cared for by  anesthesiologists with specialized pediatric training.  Whether specialized training should be mandated for older children is debatable.  Policies to define a minimum age limit for patients of general anesthesiologists may be a hot topic for the future.

HOW DOES A SURGERY CENTER INVESTIGATE IF A SURGEON IS PRACTICING BELOW THE STANDARD OF CARE?

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

Clinical Case for Discussion:    You are the Medical Director of a freestanding surgery center.  A surgeon at the facility has a serious perioperative complication which leads to a bad outcome.  You believe that his management was below the standard of care.  What do you do?

Discussion:    You put on your best Dirty Harry sneer and say, “Punk, we don’t want your kind in these parts no more.”  Then you wake up from your daydream, and deal with the reality of an unpleasant responsibility.  Playing policeman with your surgical colleague’s privileges is not on any anesthesiologist’s Top Ten list.

There is a growing trend of surgical cases moving away from hospitals to freestanding facilities.   Each of these outposts must have medical leadership.  Anesthesiologists are ideally suited for Medical Director jobs, because of their training and expertise in perioperative patient care.  In addition, duties include quality assurance (QA) monitoring, setting policies and procedures, preoperative consultation regarding appropriateness of particular patients for the facility, and medical staff credentialing.

The phrase “Standard of Care” is defined as “the level at which an ordinary, prudent professional having the same training and experience in good standing in a same or similar community would practice under the same or similar circumstances.”  When a physician is suspected of practicing below the standard of care, the facility he or she is practicing at may initiate an investigation of his or her clinical practice.  In addition, if there was an adverse patient outcome, the medical malpractice system may initiate legal action to investigate the physician’s role in the adverse outcome.

This column will discuss only the investigation of the physician by the medical facility, and will not address the workings of the medical malpractice system.

When an adverse patient outcome occurs, the QA system at a surgery center begins with telephone calls to the Medical Director to inform him or her of the event, followed by written incident reports to document the details of what occurred.  The Medical Director is responsible for screening for:

(1) errors in the system which contributed to the patient’s outcome,

(2) errors in judgment, or

(3) practice below the standard of care.

Goals are to:

a)  improve any system problem which lead to the complication,

b)  identify  educational opportunities to prevent future incidents, and

c) identify if an individual may have practiced below the standard of care.  The medical-legal system defines standard of care as what a reasonably competent practitioner of that specialty would do in the same setting.

What will you do as Medical Director if after careful review of the medical records and incident reports, you believe the surgeon’s management was below the standard of care?   Each facility you work at, including a hospital or any surgery center, has a document called the Medical Staff Bylaws.  Most physicians throw their copy into a file cabinet and never read it.  In a case like we are examining today, the Bylaws are the road map for what to do next.  A typical Bylaw pathway might be as follows:   (Reference:  Bylaws of the Waverley Surgery Center in Palo Alto, California.)

(1) Investigation.  The QA committee, with representatives of all specialties, reviews the case.   (At  different institutions, this committee may have  a different name,  such as the Medical Advisory Committee, or the Medical Care Evaluation Committee.)   They may appoint an Ad Hoc Investigation Committee of relevant specialties to gather facts and circumstances.  The Investigation Committee will report back to the QA committee with their consensus.

(2) Interview.  The physician is interviewed by the QA committee.

(3) Actions.  The QA committee may:   a) take no action,  b) issue a warning,  c) recommend a term of probation,  d) recommend a reduction or suspension of privileges, or  e) recommend suspension or revoking of medical staff membership.

(4) Request for a hearing.  The physician may appeal and request a hearing following suspension or revoking of privileges.  An Ad Hoc Hearing Committee composed of unbiased members of the medical staff not previously involved in the investigation is chosen.  The physician is physically present for the hearing, and may have an attorney present.  The meeting is tape recorded, and all evidence is heard.  The majority decision of the Hearing Committee is usually final.  A system for appeals exists.

(5) Any suspension or revocation of privileges must be reported to the Medical Board of California, and the National Practitioner Data Bank.  Being reported to these two is a very big deal.  In the surgeon’s future, every application to every hospital or surgery center, and every medical license renewal would have to include this information.

Despite the obvious perks of stretch limousines, penthouse suites, and groupies,  the Medical Director job comes with some serious responsibilities.  Investigating another physician’s practice is difficult, time-consuming, and can be emotionally taxing for everyone involved.  Ignoring potentially substandard care is a mistake, however, that can result in further mishaps and the possibility of further patient harm in the future.

Dirty Harry exists for doctors too, but it is a system, not an individual, that does the dirty work. The Quality Assurance investigative system is a chore and and obligation for a Medical Director, but it’s an important and essential chore.

THE ANESTHESIA CONSULTANT

Clinical Case for Discussion: It is the conclusion of a craniotomy for a tumor resection on a 50-year-old, 80 kg woman.  The operating room table is turned 180 degrees, you are the sole anesthesiologist. and you are at the patient’s feet.   The nurse and scrub tech are applying the head dressing.  The patient coughs, turns her head, and the endotracheal tube comes out above the vocal cords.  What do you do?

Discussion:    You have been peering intently at the monitors and the patient for the past 4 uneventful hours, seeking the perfect anesthetic, but now you have some urgent work to do.

The approach to acute medical care is always:  Airway, Breathing, and Circulation.

In this case, the airway is distant from you and your equipment, because the surgeon needed full access to the head for the surgery.  Your first move is to go to the head of the table, and attempt to push the endotracheal tube (ETT)  back into the trachea.  This is not successful.  The oxygen saturation is 100%, so the patient is in no immediate danger.  You unlock the OR table, and and rotate it back so that the patient’s head is next to the anesthesia equipment again.  You  remove the ETT, apply a mask to the patient, and manage the airway as the patient awakens from anesthesia.

What if the oxygen saturation had dropped below 90% when the ETT fell out?

The answer is the same.  You take the time to turn the table so that the patient’s head is back adjacent to your airway equipment and anesthesia machine, and then you use mask ventilation to return the patient’s oxygenation to a safe level.  To deliver continuous positive airway pressure (CPAP) or positive pressure ventilation to your patient, you need to be able to reach both the ventilation bag and hold the mask over the patient’s face.  You can not do this if the table is turned 180 degrees.  If the patient develops laryngospasm that you can not break with CPAP, a small dose of succinylcholine (10 – 20 mg) is recommended.

Any attempt to manage the airway problem with the table still turned 180 degrees, but relying on the surgeon or the circulating nurse to hand you drugs and equipment, or to squeeze the bag on the circle system, is not recommended by this author.  Their skill level may not be what you were used to in  your residency training, when you were sharing the responsibility with a second anesthesiologist.

What if, in a parallel universe, at the onset of this same scenario a different anesthesia provider inserted the laryngoscope into the patient’s mouth to attempt to replace the ETT.    The patient bit down on the blade, and the anesthesiologist wrestled with a forceful laryngoscopy.  The oxygen saturation dropped below 90%.  He decided to inject succinylcholine to paralyze the patient, but his drugs and syringes were at the foot of the operating room table, six feet away and out of reach.  He instructed the nurse to draw up and inject the drug for him, but this took over 60 seconds of valuable time, during which the patient was hypoxic.  He finally inserted the ETT into the trachea, and was able to ventilate the lungs to increase the oxygen saturation to 100% again. But the blood pressure was now 180/110, the heart rate was 140 beats per minute, and the intracranial pressure was higher than the surgeon’s temper at this point.

Make a different choice:  turn the head end of the operating room table back to where your equipment is.

Regarding the possibility of the ETT coming out during surgery, I anticipate comments like:   “How could this happen?  Why didn’t you use Benzoin to hold the ETT tape to the skin overlying the maxilla?  Why did you tape the tube to the mandible instead of the mandible? You should hold the ETT yourself when you are awakening a patient and they are applying a head dressing.  You should keep the patient anesthetized until the dressing is done,” etc.

Alas, despite experience and planning, unexpected events do occur.  Your worth as a clinician will be proven and tested by how you handle the unexpected.

In sum:  If you are working alone, and an airway problem occurs with the airway six feet away from your anesthesia equipment, I advise you to bring the airway back to your equipment.

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.

ANESTHESIOLOGIST TRAINING:

Anesthesiologists are Medical Doctors.  In the United States, anesthesiologists are required to have the following minimum training following high school:

1.  College degree = 4 years

2.  Medical school degree (M.D. or D.O.) = 4 years

3.  Internship = 1 year

4   Residency in Anesthesiology = 3 years

This minimum timeline adds up to 12 years after high school.  Most anesthesiologists are 30 years old or older before they are finished training.

BOARD CERTIFICATION by the American Board of Anesthesiology requires passage of both a written and an oral examination.  Neither exam is administered until all training is concluded, and most anesthesiologists are 31 years old or older before they are are board certified.

ANESTHESIA FACTS FOR LAYPEOPLE: CHILDBIRTH, CARDIAC SURGERY, AND BRAIN 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

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.

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.

THE ANESTHESIA CONSULTANT

INTRAVENOUS MEDICATIONS:

1.  PROPOFOL.  Propofol is an intravenous sedative-hypnotic, and the most commonly used general anesthetic medication in the United States.  Because propofol can cause the patient to stop breathing, its use is restricted to physicians who are expert in the management of airway and breathing.  Propofol has ultra-fast onset and offset times, usually causing sleep within seconds of injection.  Because the drug is short-acting, it is often administered by a continuous intravenous drip or infusion When propofol is administered without other anesthetic drugs, the patient usually awakens within minutes of discontinuing the drug.  Propofol does not relieve pain, and most painful surgeries require additional medication(s).

2.  MIDAZOLAM (Brand name VERSED).  Midazolam is a short-acting anxiety-reducing drug of the Valium or benzodiazepine class.  Midazolam is commonly injected as the first drug to begin an anesthetic, because it gives patients a sense of calm, and often gives them amnesia for a period of minutes afterward.  Midazolam is a common drug given during sedation for colonoscopy procedures, because most patients have no awareness during the procedure, even though they are usually awake.

3.  NARCOTICS.  Most surgical procedures cause pain, and narcotic drugs are intravenous pain-relievers.  Commonly used narcotics are morphine, meperidine (brand name Demerol), fentanyl, and remifentanil.  Narcotics have the desired effect of dulling the brain’s perception of pain.  Narcotics cause sleepiness in higher doses, and have the common side-effect of nausea in some patients.  Morphine and Demerol are slower-onset, longer-lasting narcotics, while fentanyl and remifentanil are faster-onset, shorter-acting narcotics.

4.  PARALYZING DRUGS.  Some surgeries and anesthetics require the patient to be paralyzed, i.e. muscles must be rendered flaccid so that the patient can not move.  It is imperative that the patient be given adequate intravenous or inhaled anesthetic drugs first, so that the patient has no awareness that they can not move.  Commone paralyzing drugs are vecuronium, rocuronium, pancuronium, and succinylcholine.  Because paralyzing drugs cause the patient to stop breathing, their use is restricted to physicians who are expert in the management of airway and breathing.  Paralyzing drugs are used by anesthesia providers prior to the placement a breathing tube (endotracheal tube) into the patient’s windpipe (trachea).  Paralyzing drugs are used during certain surgical procedures in which the surgeon requires the patient’s muscles to be relaxed, for example, abdominal surgeries, some throat surgeries, and some surgeries inside the chest.

INHALED ANESTHETICS:

1.  POTENT INHALED ANESTHETICS.  Potent inhaled anesthetics include sevoflurane, isoflurane, and desflurane.  These drugs are liquids, administered via anesthesia vaporizers than turn them into inhaled gases.  They are usually administered in low concentrations (1% to 4% for sevoflurane, 1% to 2% for isoflurane, and 3% to 6% for desflurane), because sustained higher concentrations fo these drugs cause life-threatening depression of heart and breathing functions.  Because potent inhaled anesthetics can cause patients to stop breathing, their use is restricted to physicians who are expert in the management of airway and breathing.

2.  NITROUS OXIDE.  Nitrous oxide is a relatively weak inhaled anesthetic drug, usually administered in concentrations of 50% to 70%.  At these doses, nitrous oxide does cause significant sleepiness, but will not render the patient unconscious.  Nitrous oxide has the advantage of being a quick-onset, quick-offset drug, and it is non-expensive.  Because every patient must inhale a minimum of 21% oxygen, the maximum dose of nitrous oxide is 100 – 21, or 79%.  As a measure of safety, oxygen is usually administered at concentration of at least 30%, which is the reason why administered nitrous oxide concentrations rarely exceed 70%.

LOCAL ANESTHETICS:

1.  LIDOCAINE.  Lidocaine is injected into tissue to block pain at that site.  The onset of local anesthesia occurs within seconds, and the duration is short, usually less than one hour.  Lidocaine can be injected into the back during either a spinal anesthetic or an epidural anesthetic, to numb part of the patient’s body without causing unconsciousness.  Lidocaine can also be injected near major nerves, in what is called a nerve block.  Nerve blocks include injections to numb one arm, one leg, the hand, or the foot.

2. PROCAINE (Brand name Novocaine).  Although the term Novocaine is commonly heard, use of this drug has been largely abandoned, replaced by lidocaine instead.

3. BUPIVICAINE (Brand name Marcaine).  Bupivicaine is injected into tissue to block pain at that site.  The onset of local anesthesia occurs within minutes, and the duration is longer than lidocaine, usually from 2 – 6 hours, depending on the location of the injection.  Bupivicaine can be injected into the back during either a spinal anesthetic or an epidural anesthetic, to numb part of the patient’s body without causing unconsciousness.  Bupivicaine can also be injected near major nerves, in what is called a nerve block.  Nerve blocks include injections to numb one arm, one leg, the hand, or the foot.

ANESTHESIA FACTS FOR LAYPEOPLE: HOW SAFE IS ANESTHESIA?

THE ANESTHESIA CONSULTANT

Deep down, every surgical patient has the same worry:  How safe is anesthesia and surgery? 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.  These statistics reflected the frequency of all patients, healthy or ill, who died in the operating room.

However, this conclusion that anesthesia mortality has plummeted is not universal.  When mortality is defined as any patient who dies 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, which challenged the Institute of Medicine report.

Lagasse presented data on surgical mortality from two academic New York hospitals between the years 1992 and 1999.  When mortality was defined as anydeath 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.

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.   However, 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.  Five percent 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. The authors of this data wrote, “Death during the first year after surgery is primarily associated with the natural history of preexisting conditions. However, cumulative deep hypnotic time and intraoperative hypotension were also significant, independent predictors of increased mortality. These associations suggest that intraoperative anesthetic management may affect outcomes over longer time periods than previously appreciated.”

In a recent update, Dr. Jeana Havidich, an associate professor of anesthesiology at Dartmouth-Hitchcock Medical Center in New Hampshire, presented the following preliminary data at the October 2014 American Society of Anesthesiologist convention:

  1. From more than 3.2 million cases of anesthesia use between 2010 and 2013, the rate of complications decreased from 11.8 percent to 4.8 percent. The most common minor complication was nausea and vomiting (nearly 36 percent) and the most common major complication was medication error (nearly 12 percent).
  2. The death rate remained at three deaths per 10,000 surgeries/procedures involving anesthesia.
  3. Among the other findings: complication rates were not higher among patients who had evening or holiday procedures; patients older than 50 had the highest rates of serious complications; and healthier patients having elective daytime surgery had the highest rates of minor complications.

Data published in 2015, in a study of mortality in surgical cases from 2010 to 2014 (Whitlock EL, Feiner, JR, Chen LI, Perioperative Mortality, 2010 to 2014 A Retrospective Cohort Study Using the National Anesthesia Clinical Outcomes Registry. Anesthesiology, V 123, No 6, Dec 2015, 1312-1321) showed the following:

  1. The authors analyzed 2,866,141 cases and 944 deaths (crude mortality rate, 33 per 100,000)
  2. Independent risk factors for higher mortality were: emergency case status, surgical cases beginning between 4 p.m. and 6:59 a.m., patient age less than one year or greater than or equal to 65 years, and sicker patients with an increased American Society of Anesthesiologists physical status score.

Anesthesia is safer than it has ever been, but risk factors such as emergencies, very young or old patients, or sicker patients, do increase the risk. The new finding in this 2015 publication was that surgeries which began late in the day or night (after 4 p.m. until 6:59 a.m.) had increased mortality.

Clinical Case for Discussion:   A 44-year-old man is scheduled for a knee arthroscopy.  He takes Prilosec for Gastro Esophageal Reflux Disease (GERD).  He is six feet tall, weighs 70 kg, and refuses regional anesthesia.   Regarding airway management for general anesthesia, you may choose a Laryngeal Mask Airway (LMA) or an endotracheal tube.  What do you do?

Discussion:   The symptoms of esophageal reflux and heartburn are exceedingly common in our society.  For years the histamine-2 blockers such as cimetidine and ranitidine were among the top money-making prescription drugs in America, before they became the over-the-counter bestsellers they are today.  Open any weekly magazine such as Newsweek or Sports Illustrated and you may find full page ads for Nexium and Protonix today.   People hurt, and they want these pills.

This is relevant in an anesthesia practice because a large percentage of patients will answer “yes” to the question of heartburn or GERD in a pre-operative questionnaire.   Thus GERD goes on their chart as a diagnosis.  How important is this?  Are they an ASA I or an ASA II, based on GERD?  Do they need endotracheal intubation for general anesthesia to prevent the dreaded complication of pulmonary aspiration of gastric contents?

Miller’s Anesthesia, a leading textbook, says,”The incidence of aspiration of gastric contents is infrequent in fasted elective surgical patients. Despite improvements in several surrogate measures, insufficient evidence exists of clinical benefit (i.e., a reduction in morbidity or mortality from aspiration) to recommend the routine use of antacids, metoclopramide, H 2 -receptor antagonists, or proton pump inhibitors before elective ambulatory surgery. Patients who are receiving these medications chronically should take them before surgery. Patients who regularly suffer from significant acid reflux in the fasted state will also benefit from the head-up tilt position during induction of anesthesia.” (Smith I. Ambulatory(Outpatient)Anesthesia, Miller’s Anesthesia.10e,Chapter 89.2015; 2612-2645)

The same textbook says, “Many ambulatory surgical patients can be managed with an LMA, which results in a significantly less frequent incidence of sore throat, hoarseness, coughing, and laryngospasm compared to inserting a tracheal tube. The LMA can occasionally cause pressure trauma to a variety of cranial nerves, in particular the recurrent laryngeal nerve, whereas hoarseness and vocal cord injuries are common after the use of endotracheal intubation during short-term anesthesia. The LMA is relatively easy to insert with patients in the prone position, 230 making it a simple way of managing procedures such as pilonidal sinus repair or surgery to the short saphenous vein.”

In 2010 I submitted the Clinical Case above to the twenty-plus attending anesthesiologists in private practice in Palo Alto who are members of the Palo Alto Medical Foundation/Sutter or the Associated Anesthesiologists Medical Group. What follows is a consensus of what the majority do, every day, in operating rooms in the heart of Silicon Valley:

If the patient had GERD which was well-treated on medication, and had no symptoms at present, my colleagues said they would use an LMA for airway management, rather than intubate the patient’s trachea. If the patient had active symptoms of GE reflux that were not under control or had gastric paresis, then they would use an endotracheal tube following cricoid pressure.

One could be dogmatic and say this:  If a patient has GERD, then intubate the trachea with a rapid sequence intubation each time, or you run the risk of aspiration pneumonitis. However, no data exist to support this practice. There is no prospective, randomized trial that documents an endotracheal tube is more safe than an LMA in an NPO GERD patient for routine outpatient minor surgery.

The ProSeal LMA has a larger cuff, and a drain tube inside the cuff, which allows the insertion of a gastric tube to drain the stomach.  There is a case report in which an anesthetized patient with a ProSeal regurgitated 25 ml of brown fluid into the drain tube.  The conclusion was that the ProSeal protected the airway by allowing the regurgitated fluid to pass up the drainage tube without leaking into the glottis.  (Evans NR, Can J Anaesth. 2002 Apr;49(4);413-6).   The ProSeal may have a role in the GERD patient population, but to date there is little data to compare it to a classic LMA in this setting.

No physician anesthesiologist would use an LMA in a patient who was not NPO. No one would use an LMA in a patient for emergency surgery, or for a patient with a bowel obstruction. No one, or very few, would use an LMA in a patient who was morbidly obese, or a patient who was having a laparoscopy.

But for a routine outpatient surgery on an NPO patient with controlled GERD, most anesthesia professionals feel safe using an LMA rather than an endotracheal tube. There are anesthesiologists — well trained graduates of the Stanford anesthesia residency program — who use an LMA in this situation. The good news is that the prevalence of clinically important aspiration in otherwise healthy NPO patients is negligible.  I believe that is why most of my colleagues choose the LMA in this case.

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.

PRODUCTION PRESSURE IN THE OPERATING ROOM

THE ANESTHESIA CONSULTANT

Clinical Case of the Month:  The head of your anesthesia group tells you that both the surgeons and the fellow anesthesiologists in your group want you to work faster, and if you do not, you will not make partner in that group.  You are worried about succumbing to “production pressure.”  You don’t want to work faster.  What do you do?

Discussion:   At the end of your day in the operating room, the most important issue is the safe medical care of each patient you were asked to consult on.  Patients don’t care if you were a racehorse or a turtle; they only care about their results.  Your malpractice insurance company doesn’t care if you were a racehorse or a turtle; they want you to practice at or above the standard of care, and not get sued.

I refer you to the article “Production Pressure in the Work Environment, California Anesthesiologists’ Attitudes and Experiences,” by David Gaba and Steve Howard of the Stanford faculty (Anesth, 1994 Aug;81(2):488-500).   The authors mailed a survey to California anesthesiologists, seeking their responses to questions pertaining to production pressure.  The authors noted that “Every modern industrial activity involves a balance between production efficiency and safety.”  They defined production pressure as “overt or covert pressures and incentives on personnel to place production, not safety, as their primary priority.”

Fifty-four per-cent of respondents agreed they had made an error attributable to fatigue, and 63% suggested that they had made errors because of the work load within a case.  Most respondents believed they had a duty to cancel cases if necessary, but 35% indicated that it was possible they would lose their job if they canceled too many cases.

The types of pressure were divided into two categories:  internal pressures (pressures anesthesiologists put on themselves), and external pressures (pressures from surgeons, family, colleagues, or administrators).  The greatest internal pressures were:  a) to avoid delaying surgery, b) to get along with surgeons, and c) to avoid litigation.  The greatest external pressures were:  a) from the surgeon, to proceed with a case instead of canceling, b) from the surgeon, to hasten anesthesia procedures, and c) from administrators, to reduce turnover time.

Fee-for-service respondents reported more internal pressure than did salaried practitioners to:  maximize cases (P=0.0007), accrue income from high paying cases (P=0.0001), and avoid litigation (P=.0002).

I worked a short stint in a salaried anesthesia job with Kaiser in 1986, before I began working in my current arrangement of fee-for-service (FFS) practice.  Production pressure exists, and I can attest that it is more apparent in FFS practice.  In FFS practice, you have incentives to proceed with cases rather than cancel them, to turn over rooms quickly rather than take a 30-minute lunch break, and to keep your surgeon-customers happy rather than fight with them over cancellations.

I discussed today’s question with other anesthesiologists in top Bay Area FFS practices.  Among their expectations for new hires is that the individual will possess The Three A’s, of Ability, Availability, and Amiability.  Part of the Ability ingredient is the talent to multi-task, that is, the ability to work with your hands, do paperwork, think, plan anesthetics, and monitor your patient simultaneously.

Some anesthesiologists are racehorses, and some anesthesiologists are turtles.  Consider this:  All else being equal, the turtles will not last in FFS job opportunities.

Surgeons in private practice in are faster than surgeons in residency.  When you graduate and enter the private practice of anesthesia, you will have to speed up to succeed.  The message here is a wake-up call:  Don’t stand in the middle of the operating room and complain about production pressure.  Work as efficiently as you can.  Do not take short-cuts that endanger your patient, but get the job done.

If it sounds like I am applying production pressure with my comments, you may be right.  Safety is the number one goal, but high production is an expectation, and not an unreasonable one.

The years of residency and fellowship are the time to hone your skills.  Attempting to work at an efficient pace during the first weeks of your first FFS job will be impossible if you haven’t valued efficiency in your training.  If you are a turtle, will you lose your job?  I know of several anecdotes where private FFS anesthesia groups washed out promising candidates because they were too slow for the private world.  The candidates spent too much time starting IV’s and other lines, getting their patients to sleep, placing regional anesthetics, waking their patients up, taking longer-than-expected breaks between cases, and arguing with surgeons instead of getting patients anesthetized.

Some surgeons are better than others.  Anesthesiologists, nurses, and OR techs all know which surgeons possess excellent judgment and are skilled with their hands.   In the same light, surgeons, nurses, and OR techs all know which anesthesiologists possess excellent judgment and are skilled with their hands.

You want to be one of the anesthesiologists they admire.

If the pace of the FFS world feels unsafe to you, I would advise you to find a different job model, perhaps a salaried job at a more languid tempo.  In a FFS practice, you need to be both safe and efficient.

HOW MANY SYRINGES DOES IT TAKE TO GIVE A GENERAL ANESTHETIC?

THE ANESTHESIA CONSULTANT

Clinical Case of the Month:   You’re setting up to give anesthesia for a laparoscopic cholecystectomy.  How many syringes and labels do you draw up and prepare?  For a D & C?  For an open abdominal aortic aneurysm repair?

Discussion:  Try something new.  When  preparing for a cholecystectomy, open two syringes, both unlabelled, and don’t open any ampules until the patient is in the OR.  More on that later.

Let’s examine two questions:  Why do we label syringes, and why do we load syringes with drugs ahead of time?  The answer to the first question is easy — we label syringes because we want to know what’s inside of them.  The Institute of Medicine’s report from 1999, entitled, To Err is Human:  Building a Safer Health Care System, reported that 98,000 patients died in U.S. hospitals each year due to medical errors.  Administering the wrong drug is a known anesthesia risk which we all try to avoid.

In a study of 55,426 anesthetics in Norway over 36 months, drug error was reported in 63 cases, or 0.11% of cases. (Fasting S, Can J Anaesth.2004 Oct;51(8):853-4.)  Drug errors included 28 syringe swaps, 9 ampule swaps, 8 ‘other wrong drug’ cases, and 18 cases where the wrong dose of the correct drug was given.  In the second 18 months of their study, they switched to color-coded syringe labels, and found their results unchanged except for a decreased number of ampule swaps (P=.04).  They concluded that drug errors were uncommon, that syringe swaps occurred most often between syringes of equal size, and that drug errors were not eliminated by color-coding of labels.

In a study of 896 drug errors reported in Australia, syringe and drug preparation errors accounted for 452 (50.4%) incidents, including 169 (18.9%) involving syringe swaps where the drug was correctly labeled but given in error, and 187 (20.8%) due to selection of the wrong ampule or drug labeling errors. (Abeysekera A, Anaesthesia. 2005 Mar;60(3):220-7).  Contributing factors included inattention, haste, drug labeling error, communication failure, and fatigue.  Factors minimizing the events included prior experience and training.

According to the first reference, a drug error was reported about once per 1000 cases in Norway.  I’d ask you to consider how many incidents of drug error occur, versus how many are actually reported.  I submit that the real prevalence probably exceeds the amount of cases that anesthesiologists admit to, and the real prevalence is significantly greater than .11%.  And even though labeling syringes is important and mandated, it fails to decrease medication error to zero.  In the future, we may see computerized visual and auditory bar-code verification of ampules and/or labels just before drug administration.

My second question to you was “why do we load syringes with drugs ahead of time?”  Common sense answers might be, “because it makes our work more efficient,” or “we might need them fast, and we don’t want to draw the drugs up at the last moment.”  Opinions regarding the preparation of pre-drawn emergency syringes differ.  In a study from New Zealand, a quarter of respondent anesthesiologists routinely drew up emergency drugs, and a third either never or very infrequently did so(Ducat CM, Anaesth Intensive Care. 2000 Dec;28(6):692-7).  Among the drugs most commonly drawn up were succinylcholine, atropine, and ephedrine.  Pediatric, obstetric, or vascular cases were cited as factors which prompted anesthesiologists to draw up one or more of these drugs.

Drug wastage is a known to be a significant portion of anesthesia drug budgets.  In one fiscal year, the cost of unadministered drugs at Rhode Island Hospital was $165,667 (Gillerman RG, Anesth Analg. 2000 Oct;91(4):921-4).  Efficiency indexes, defined as the percent of a restocked drug that was actually administered to patients, were as follows:  succinylcholine, 33%, propofol, 49%, rocuronium, 61%, and thiopental, 31%.  In a study at UC San Diego, drug wastage was quantitated in 166 cases during  a two week period (Weinger MB, J Clin Anesth. 2001 Nov;13(7):491-7).  Based on hospital drug acquisition costs, $1802 of drugs were wasted in two weeks.  Six drugs accounted for three quarters of the total wastage:  phenylephrine (20.8%), propofol (14.5%), vecuronium (12.2%), midazolam (11.4%), labetolol (9.1%), and ephedrine (8.6%).

Think about it, my colleagues.  Do you really need to draw up atropine and ephedrine before every case?

I queried Fred Hurt from the Stanford OR Pharmacy, and he gave me the following drug ampule acquisition costs:  atropine $.23, ephedrine $.74, phenylephrine $2.47, vecuronium $2.51, rocuronium $18.89, succinylcholine $1.93, propofol 20ml $4.76, and propofol 50 ml $11.91.

I’ll admit, in the scope of the healthcare budget of the United States, these numbers are miniscule, and you may not give a damn if your unused atropine and ephedrine costs Stanford 97 cents.  But let’s go back to the first paragraph, and a technique to avoid drawing up a lot of drugs and labeling them.  Part of the rationale is to avoid drug wastage, but the greater issue is the KISS principle — Keep It Simple Stupid.  In a 20 year career you’ll do 14,000 cases, and any practice that avoids wasted time and energy on each case is of value.

Try this:  For a cholecystectomy, use an unlabelled 5 ml syringe to draw 2 mg of midazolam from its already labeled ampule, and inject it into the patient’s IV.  Minutes later, use the same syringe to draw 100 micrograms of fentanyl from its already labeled ampule, and inject it into the patient’s IV.  Then use a second syringe, a 20 ml syringe, to draw 200 mg of propofol from its already labeled ampule, and inject it into the patient’s IV.  Finally, use the first syringe to draw 10 ml of Lactated Ringers from the IV bag and inject it into an already labeled ampule of vecuronium, mix it up, and inject 0.1mg/kg of vecuronium into the patient’s IV.

Reusing the same syringe on the same patient for several single-patient use ampules is safe.  The ampules are already labeled — why add another intermediate step and store them in a labeled syringe?  The exception to this practice is for drugs that need to be diluted — this would include phenylephrine (for a case you expect you might need it, such as vascular surgery or geriatric surgery), or narcotics such as morphine and meperidine.  These syringes need to be prepared and labelled.  Syringes should not be carried over from one patient to the next.

Like Burger King used to say, “Have it your way!”  You don’t have to agree with or accept the above suggestions, but I’d be interested in hearing if you’ve changed your mind, 14,000 cases from now.

IS IT SAFE TO GIVE BETA-BLOCKERS TO ASTHMATIC PATIENTS?

THE ANESTHESIA CONSULTANT

Clinical Case of the Month:  A 62-year-old asthmatic with obstructive sleep apnea develops a heart rate of 125 and a blood pressure of 160/95 in the Recovery Room, thirty minutes following a UPPP.  His pain is well controlled, and he has no dyspnea or chest pain.  The patient is two years status-post an inferior myocardial infarction, and is known to have 60% occlusions of his left anterior and circumflex coronary arteries.  The nurse asks if you can use a beta blocker in asthma patients.  What do you do?

Chemical formula for propanolol, the first beta blocker

 

Discussion:   By the time you receive the call from the Recovery Room, you’ve already returned to the OR.  You’ve already induced and intubated your next patient.  You give the Recovery Room nurse a verbal order to administer 10 mg of IV labetolol.  The nurse calls back five minutes later, and says that the patient developed severe wheezing, the oxygen saturation dropped to 60%, and he’s complaining of substernal chest pain.  You call one of your partners to take over your anesthetized patient, and you rush to the Recovery Room.  You arrive just in time to witness your cyanotic wheezing patient go into cardiac arrest.

A miserable scenario.  Is it possible?  If your patient died, do you think a plaintiff’s attorney would be willing to sue you for malpractice?  Can you imagine this question at the deposition:  “Doctor, what were you thinking when you treated this patient with known bronchospastic disease with a drug known to reverse beta-mediated bronchodilation?”

There are multiple case reports in the medical literature where non-selective beta-blockers led to exacerbations of bronchospasm in patients with asthma.  As recently as 1995, one could find admonishments like this in the medical literature:  “Worsening or precipitation of asthma by beta-adrenoceptor antagonists is well recognized. Severe bronchoconstriction may be induced even in ‘mild’ asthmatics, and the dose of beta blocker required may be low, as in the case of eye drops of timolol, a nonselective beta blocker used to treat glaucoma. The severity of bronchoconstrictor response is not predictable. Nonselective beta blockers are more likely to precipitate bronchospasms in patients with asthma. The mechanism of beta-blocker-induced asthma is still not certain. Normal subjects develop neither a deterioration in lung function nor an increased bronchial hyperreactivity; therefore, beta blocker drugs should in general be avoided by asthma patients.”  (Im Hof, Schweiz Rundsch Med Prax. 1995 Mar 14;84(11):319-20).

Let’s step back to paragraph one, and think things over again.  Because your tachycardic, hypertensive patient has coronary artery disease, you are concerned about his risk for an acute cardiac event.  You run through a quick benefit-risk analysis.  If you do nothing, the patient may develop angina or a myocardial infarction.  If you treat the hypertension with a vasodilator, you can decrease the blood pressure, but you’re likely to increase heart rate further.  If you give a beta-blocker, you’re aware that there is some risk of inducing bronchospasm.

What about a beta-1 cardioselective beta-blocker?  How safe would a beta-1 blocker be in this situation?  You order the nurse to titrate in 2 mg IV increments of metoprolol.  After 6 mg, the heart rate decreases to 72 beats per minute, and the blood pressure is 110/75.  The patient does not develop wheezing.

In their paper Safety of therapeutic beta-blockade in patients with coexisting bronchospastic airway disease and coronary artery disease (Am J Ther. 2003 Jan-Feb;10(1):48-50), S. Khosla et al prospectively followed 835 consecutive outpatients with symptomatic coronary artery disease at Mt. Sinai Hospital in Chicago.  Thirty of the 835 patients had concurrent bronchospastic disease.  All patients were treated with an oral beta-1 antagonist.  Twenty-nine of the thirty patients attained successful beta blockade (defined as heart rate less than 70) without bronchospasm.  One patient discontinued the beta-1 blocker as a result of lifestyle-limiting bronchospasm.  He had no serious adverse outcome, and did not require hospitalization.  The authors concluded that selective beta-1 blocker usage was safe in this population.

What about intravenous beta-1 blockers in the setting of acute cardiovascular disease?  In their paper, Beta-blocker therapy of cardiovascular diseases in patients with bronchial asthma or COPD: The pro viewpoint, Ashrafian and Violaris reported:  “Extensive randomized clinical trial data support the view that beta-blockers have a significant impact on the prognosis of patients with cardiovascular disease, especially those with coronary artery disease and chronic heart failure. Unfortunately, this essential treatment is often withheld from patients with asthma and from some patients with Chronic Obstructive Pulmonary Disease (COPD). The principal concern, a concern supported by a number of guidelines, is that beta-blockers may precipitate severe and potentially fatal bronchospasm. However, a number of studies, culminating in a recent meta-analysis, show that cardioselective beta-blockers are not only safe but are beneficial in patients with co-existing airways and coronary disease. In this article we review the evidence supporting the position that cardioselective beta-blockers, when introduced with care in both community and hospital settings, are safe in patients with mild airways disease and can significantly improve prognosis.” (Prim Care Respir J. 2005 Oct;14(5):236-41).

Although I was unable to find a prospective, randomized trial documenting the safety of intravenous beta-1 blockers in patients with both bronchospastic disease and coronary artery disease, it’s my impression that the literature supports this practice.

I queried the other private practice anesthesiologists on the faculty at Stanford University Hospital regarding their use of beta-blockers in asthmatic patients, and the results were consistent.  The private attendings favored a risk-benefit analysis, but almost everyone admitted to titrating small doses of beta-1 antagonists, when indicated, in patients with bronchospastic disease.  None of my colleagues reported a complication with this practice.

When I finished my Stanford anesthesia residency in 1986, almost no one dared to give IV beta-blockers to an asthmatic.  Things change. That’s my advice to the residents of today:  keep on reading after residency, because . . . things will keep changing.

THE ANESTHESIA CONSULTANT

Clinical Case of the Month:  A 5-year-old boy is scheduled for general anesthesia for a cochlear implant.  On your pre-operative phone call to the mother, she tells you that after the same surgery on the other ear, the child was severely agitated in the Recovery Room.  The last anesthesiologist told her that agitation was a common side effect for the sevoflurane anesthetic that was used.  What will you do?

Discussion:  How about this plan:  You obtain the old anesthesia record, duplicate the technique exactly, and give earplugs to everyone within ten yards of the Recovery Room?  Don’t buy it?  Read on.

Before you begin, a colleague says,  “Who cares about crying?  As long as the anesthetic care is safe, crying in the PACU is no big deal.  It’s a sign of an adequate airway.”  He continues:  “Why, I went on an Interplast trip fixing cleft palates in South America, and all the kids screamed in the Recovery Room.  They all survived.”

I’ve got news for him — a screaming child in the Recovery Room is a problem for several people:  the nurse, the mother of the child (she’s freaking out herself), the attending anesthesiologist (who, by inference, looks like he doesn’t know how to finish an anesthetic), and every other PACU patient within earshot.  I’d submit that the goals of a 21st Century anesthetic go beyond safety — patients or their families feel entitled to wake up as pain-free, nausea-free, and side-effect-free as possible.

Sevoflurane was introduced in Japan in the late 1980’s and in the United States in the 1990’s (Miller’s Anesthesia, 2005, p. 18).  Because of its low solubility, sevoflurane represented a significant advance over isoflurane, which dominated the inhaled anesthetic market prior to that time.  In addition to its low solubility, sevoflurane was less pungent than isoflurane and could be used instead of halothane for inhalational induction in children.  As well, sevoflurane had a lower incidence of cardiac arrhythmias than halothane.  These properties made sevoflurane the drug of choice for inhalation induction in children (Johannesson GP, Acta Anaesthesiol Scand. 1995 May;39(4):546-50).

Soon after its introduction into clinical practice, reports of sevoflurane and post-operative agitation and delirium in preschool patients began to appear in the anesthesia literature.  The described agitation was unrelated to pain, was inversely related to age, and was most frequent in children 5 years of age or younger.  (Miller’s Anesthesia, 2005, p. 2373).   Emergence delirium with sevoflurane exceeded the rate of emergence delirium with halothane.  Aono reported a 40% incidence of delirium during recovery in preschool boys aged 3 – 5 years old who underwent urologic surgery under sevoflurane, vs. a 10% incidence of delirium for those who were anesthetized with halothane (Anesthesiology, 1997 Dec;87(6):1298-300).

A variety of remedies appeared in the peer-reviewed literature over the ensuing years.  A complete discussion of all reported techniques is beyond the scope of this short column.  I refer you to PubMed with the keywords sevoflurane, agitation, where you’ll find multiple references to support multiple techniques.  Statistical significance was obtained in controlled studies with the following techniques either before or after sevoflurane induction:  use of oral midazolam prior to induction; use of a single dose of fentanyl 1 mcg/kg ten minutes prior to emergence;  conversion to propofol infusion anesthesia after induction;  conversion to isoflurane anesthesia after induction;  conversion to desflurane anesthesia after induction;  use of IV dexmedetomidine 0.3 – 0.5 mcg/kg after induction;  use of PO clonidine premedication 4 mcg/kg before induction;  or use of IV clonidine 2 mcg/kg immediately after induction.

I polled my private practice Stanford Adjunct Clinical Faculty colleagues on their preferred methods to minimize pediatric emergence delirium, and three strategies prevailed:  1) the use of heavy midazolam premedication (up to .8 mg/kg);  2) the use of titrated doses of intravenous fentanyl or meperidine prior to emergence; and 3) discontinuance of sevoflurane after inhalation induction — instead substituting isoflurane or propofol for maintenance anesthesia.  No one used dexmedetomidine or clonidine.

Let’s return to your 5-year-old patient.  You decide to utilize all three options described in the previous paragraph.  You begin with the oral midazolam premedication 20 minutes prior to induction.  (Because the duration of this surgery is estimated to be 90 minutes, you realize that most of the effect of the midazolam premed will be dissipated at the time of emergence.)   After an uneventful sevoflurane mask induction, you place an I.V. and intubate the trachea.  At this point you turn off the sevo and switch to isoflurane.  Cochlear implant surgery involves drilling into the skull, and despite use of local anesthesia by the surgeon, you can anticipate post-operative pain.  It seems prudent to use a narcotic to treat both pain and delirium.  At the conclusion of the anesthetic, you administer doses of 5 mg of meperidine, titrated to the child’s respiratory rate.  After extubation, you supplement with additional narcotic as needed to affect comfort and tranquility.  Because both the surgery and the anesthetic technique may stimulate post-operative nausea or vomiting, you administer doses of I.V. ondansetron and metoclopramide for nausea prophylaxis.  You request the mother sit at the bedside in the PACU as soon as the child begins to reawaken, as a humane non-pharmacologic method of easing the child’s emotional discomfort .

There are no trophies given for rapid wake-ups in the pediatric PACU.  Your technique produces a gradual calm emergence characterized by safe maintenance of the airway and a relaxed, comfortable child.   The 5-year-old’s mother is thrilled with the improvement over the last anesthetic, and the PACU nurses respect that you care about the quality of your patient’s wake-up.

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.

SHOULD YOU CANCEL SURGERY FOR A LOW POTASSIUM LEVEL OF 3.4 mEq/L?

THE ANESTHESIA CONSULTANT

Clinical Case of the Month:  You’re medical director for a busy outpatient surgery center.  An RN routinely does the preoperative screening by telephoning each patient two days prior to surgery.  The RN pages you with this question:  A 48-year-old patient scheduled for anterior cruciate ligament (ACL) reconstruction surgery takes hydrochlorothiazide for hypertension, and has not had electrolytes checked for six months.  His last labs show a low potassium = 3.4 mEq/L.  The patient is asymptomatic except for knee pain. The nurse asks you whether this patient needs to have his potassium rechecked now, before surgery.  What do you do?

Discussion: Pre-op evaluation will never be the topic of a Hollywood thriller — you’ll never see Tom Cruise or Brad Pitt rubbing their temples worrying about whether they need to recheck the electrolytes.  But for you and me, it’s a question worth discussing. How important is it to diagnose hypokalemia in this asymptomatic patient on chronic diuretic therapy?  If the K=3.0 mEq/L, will you cancel the surgery?  What about if the K=2.9 mEq/L?  Experienced anesthesiologists know standards of care for their specialty, and also develop a gut impression about which patients are prepared for surgery, and which ones are not.  Do you sense this patient is at risk for sudden death or a cardiac arrhythmia?  Let’s examine this question.

First off, why didn’t you see this patient in your pre-op clinic?  The answer is because you won’t find the Stanford model of a well-staffed Pre-Anesthesia Clinic in the private practice community.  The Pre-Anesthesia Clinic is important at Stanford because many patients suffer from significant medical comorbidities, and because of the invasive nature of many of the inpatient surgeries.  In a community practice with healthier patients and less invasive procedures, there is neither the money nor the need to physically meet and examine every patient several days prior to surgery.  Adam Smith’s economic dictum of the invisible hand pertains to clinical medicine as well — anesthesiologists are paid to give anesthetics.  Neither insurers nor Medicare will reimburse you for routine pre-operative clinic encounters with patients.

In 2002, the American Society of Anesthesia published Practice Advisory for Preanesthesia Evaluation:  A Report by the American Society of Anesthesiologists Task Force on Preanesthesia Evaluation. Their recommendations for the timing of preanesthesia evaluation differ, depending on the severity of disease and also on the surgical invasiveness.  Our patient’s surgery involves a non-severe comorbidity (well-controlled hypertension) and a non-invasive surgery (knee arthroscopy).  For patients such as this, the ASA Practice Advisory states, “preoperative assessment may be done on or before the day of surgery. “ In our community outpatient practice in Palo Alto, a surgery-center RN calls the patient two days prior to surgery to ask pertinent questions.  This telephone call helps avoid day-of-surgery surprises (e.g. patients still on aspirin, patients with undiagnosed chest pain or dyspnea).  The physical evaluation by the anesthesia attending occurs on the day of surgery.

Outpatient surgery centers rarely have the ability to do lab tests other than blood glucose measurements or a 12-lead ECG.  Tests such as the measurement of electrolyte concentrations need to be done at an outside lab, at least one day prior to surgery.  Regarding preanesthesia serum chemistries (i.e., potassium, glucose, sodium, renal and liver function studies), the ASA Practice Advisory gives no specific recommendation to check preoperative electrolytes during chronic diuretic therapy.  The recommendation on checking pre-op electrolytes states  “Clinical characteristics to consider before ordering such tests include likely perioperative therapies, endocrine disorders, risk of renal and liver dysfunction, and use of certain medications or alternative therapies.”

Might “perioperative therapies” include potassium replacement? Consider this: potassium is predominantly an intracellular ion.  Per Miller’s Anesthesia, “Only 2% of total-body potassium is stored in plasma. . . .  a 20% to 25% change in potassium levels in plasma could represent a change in total-body potassium of 1000 mEq or more if the change were chronic or as little as 10 to 20 mEq if the change were acute. . . . Chronic changes are relatively well tolerated because of the equilibration of serum and intracellular stores that takes place over time to return the resting membrane potential of excitable cells to nearly normal levels.” (Miller’s Anesthesia, 2005, pp.1105-6)

The same textbook states, “Retrospective epidemiologic studies attribute significant risk to the administration of potassium (even chronic oral administration).  In one study, 1910 of 16,048 consecutive hospitalized patients were given oral potassium supplements.  Of these 1910 patients, hyperkalemia contributed to death in 7, and the incidence of complications of potassium therapy was 1 in 250.” (Miller’s Anesthesia, 2005, p. 1107).

Given this information, what should we do?

Here’s the answer: Per Miller’s Anesthesia, p. 1107, “As a rule, all patients undergoing elective surgery should have normal serum potassium levels.  However, we do not recommend delaying surgery if the serum potassium level is above 2.8 mEq/L or below 5.9 mEq/L, if the cause of the potassium imbalance is known, and if the patient is in otherwise optimal condition.”

The same textbook points out an additional problem in ordering lab tests: “the failure to pursue an abnormality appropriately poses a greater risk of medicolegal liability than does failure to detect that abnormality. In this way, extra testing increases the medicolegal risk to physicians.” (Miller’s Anesthesia, 2005, p. 945)

Regarding the timing of lab testing, the ASA Practice Advisory on Preanesthesia Evaluation states “test results obtained from the medical record within 6 months of surgery are generally acceptable if the patient’s medical history has not changed substantially. More recent test results may be desirable when the medical history has changed, or when test results may play a role in the selection of a specific anesthetic technique (e.g., regional anesthesia in the setting of anticoagulation therapy.)”

For all the reasons stated above, you tell the RN that you won’t recheck the potassium lab value for this patient, and you won’t delay or cancel the ACL surgery.  The surgery is completed two days later, without complication.  Your two clients, the patient and the surgeon, are both happy, and you’ve practiced sound, evidence-based medicine.

For further details on the management of hypokalemia and hyperkalemia before, during, and after surgery, see the chapter I wrote entitled Disorders of Potassium Balance, in Complications in Anesthesia, 3rd Edition, 2017, edited by Lee Fleisher and Stanley Rosenbaum, Elsevier Press, Philadelphia.

DOES AN ANESTHESIOLOGIST NEED A STETHOSCOPE?

THE ANESTHESIA CONSULTANT

Clinical Case of the Month:   A 56-year-old internist colleague of yours is scheduled for cholecystectomy.  He has stable hypertension, asthma, and hyperlipidemia.  During your pre-op evaluation, he asks if you will be listening to his breathing and heartbeat continuously during the anesthetic.  What do you say? How do you defend your answer?

Discussion:  What’s more symbolic of the medical profession than a white coat and a stethoscope?  As anesthesiologists strive to become recognized as perioperative physicians in a changing medical world, some of us actually carry stethoscopes around our necks, like those actors on Grey’s Anatomy.

On the first day of my Stanford Anesthesia residency in July 1984, each incoming resident had foam injected in their ears for molds to supply us with custom-made individually-fitted earpieces for our mono-aural stethoscopes.  In 1984, continuous stethoscope monitoring via a precordial or an esophageal stethoscope was a standard of care practiced by residents and attendings alike.  In July 1984, the Santa Clara Valley Medical Center operating rooms had exactly two (2) pulse oximeters.  Anesthesiologists would negotiate with each other daily to determine who had the sickest patients, and therefore most needed to use one of the oximeters that day.  The Stanford University operating rooms had exactly one (1) end-tidal-CO2 monitor, used exclusively by ENT anesthesiologist Dr. Chuck Whitcher.

Pulse oximetry and capnography became widespread in the late 1980’s,  anesthesia safety statistics improved, and unexpected cardiac arrests due to undiagnosed esophageal intubations became rare. The 1999 National Academy of Sciences publication To Err is Human: Building a Safer Health System reported, “Anesthesia is an area in which very impressive improvements in safety have been made.  . . . today, anesthesia mortality rates are about one death per 200,000 to 300,000 anesthetics administered, compared with two deaths per 10,000 anesthetics in the early 1980’s.”

Once OR’s were equipped with oximeters and capnography, most anesthesiologists abandoned routine use of mono-aural stethoscopes.

A prospective single-blind study of 520 consecutive patients in 1995 (Prielipp RC, Use of esophageal or precordial stethoscopes by anesthesia providers: are we listening to our patients? J Clin Anesth. 1995 Aug;7(5):367-72.) found 68% of patients had an esophageal stethoscope placed, 16% had a precordial stethoscope, and 165 of the 520 patients had no stethoscope.  This study documented that many stethoscopes that were placed were not used — overall, providers listened continuously via an anesthetic stethoscope in only 28% of the anesthetics.

In 2001, a study from London utilized questionnaires to document that 35.2% of anaesthetists never used an oesophageal or precordial stethoscope, and the majority of the remaining 64.8% used the devices in less than one-third of their practice. (Watson A, Survey of the use of oesophageal and precordial stethoscopes in current paediatric anaesthetic practice. Paediatric Anaesth. 2001 Jul;11(4):437-42.)

Regarding auscultation, the 2005 American Society of Anesthesiologists Standards for Basic Anesthesia Monitoring says: 1) “every patient receiving general anesthesia shall have the adequacy of ventilation continually evaluated.  Qualitative clinical signs such as chest excursion, observation of the reservoir bag and auscultation of breath sounds are useful.”   2) “every patient receiving general anesthesia shall have, in addition to (ECG and blood pressure monitors) circulatory function continually evaluated by at least one of the following:  palpation of a pulse, auscultation of heart sounds, monitoring of a tracing of intra-arterial pressure, ultrasound peripheral pulse monitoring, or pulse plethysmography or oximetry.”   3) “when an endotracheal tube or LMA is inserted, its correct positioning must be verified by clinical assessment and by the identification of carbon dioxide in the expired gas.”

Are anesthesiologists in private practice in Palo Alto using esophageal or precordial stethoscopes in 2007?  An e-mail survey of the twenty-five private practice attendings on the Stanford anesthesia Adjunct Clinical Faculty revealed:  1) continuous stethoscope monitoring for adult anesthetics is almost extinct, 2) use of precordial stethoscope monitoring during inhalational induction in pediatric anesthesia is standard for most practitioners, 3) in pre-op, stethoscopes are used during cardiac and pulmonary assessment only as indicated by the patient’s history and the planned surgical procedure, and 4) most practitioners, but not all, use a stethoscope to document bilateral breath sounds after every endotracheal intubation.

Dr. Terri Homer is a former cardiac anesthesiologist who has transitioned into a busy private practice of intravenous sedation general anesthetics in dental offices, where no ETCO2 monitoring is available. Terri discussed the gulf in precordial stethoscope use between herself and the current Stanford residents in her e-mail reply.  Terri wrote, “I use a precordial stethoscope on all of my I.V. sedation cases in dental and oral surgery offices for both my pediatric and adult patients. In my opinion, there is no better monitor to assess the quality of the airway under sedation. On my GA cases in the O.R., I use a precordial on every pediatric case on induction and during maintenance. On my adult GA cases I use an esophageal stethoscope on all prone cases but not anymore on other intubated adult patients. I do not check for bilateral breath sounds on my LMA cases but I definitely still do on intubated patients of any age. When I work with a resident on my Adjunct Clinical Faculty days I am astonished that more than 95% of them have never even seen a precordial stethoscope. That’s when I start feeling like a dinosaur. When I explain the value of this monitor, I don’t think they are at all convinced.”

How should we answer our patient in the Clinical Case of the Month question above?  You tell your colleague the truth:  In light of his history of stable asthma, you will listen to his lungs in the pre-operative room and immediately after endotracheal intubation.  You do not plan to  continuously listen to his breath sounds during the cholecystectomy, but you tell him that if any change or adverse trend occurs in the vital signs, oxygenation, ETCO2 tracing, or airway pressures, you’ll have a stethoscope on his chest in a heartbeat.

WHEN HEPATITIS C WAS TRANSMITTED FROM PATIENT TO PATIENT

THE ANESTHESIA CONSULTANT

Clinical Case for Discussion: An anesthesia colleague of yours dilutes a 50-microgram ampoule of sufentanil with 9 cc of normal saline, so the final syringe concentration is 5 micrograms per cc.  He then injects 10 micrograms of sufentanil from this syringe into the clean IV line of three different patients during his OR day.  Is this practice OK?  What do you do?

Discussion:  Your colleague claims this practice is without risk because he injects into an IV port that is six feet proximal to the IV catheter.  He’s done this for twenty years, since his residency training.  He’s “never had a complication” and sees no reason to change.

He needs to change, and here’s the most recent evidence why:  In January 2008, investigators from the Center for Disease Control (CDC) responded to a request from the Southern Nevada Health District to help investigate three persons with acute hepatitis C virus (HCV) infection (MMWR Morb Mortal Wkly Rep. 2008 May 16;57(19):513-7).  All three persons had undergone procedures at a Las Vegas endoscopy clinic. CDC went on to identify a total of six cases of HCV infection among patients who had undergone procedures at the clinic in the 35–90 days prior to onset of symptoms. These patients had no other risks for HCV infection.

On investigation of the clinic, CDC observed practices that had the potential to transmit HCV.  The May 2008 issue of Anesthesiology News reported that “certified registered nurse anesthetists (CRNAs) at the center had been improperly administering anesthesia to patients undergoing routine endoscopic procedures.”  The California Department of Public Health mailed a letter to all California physicians, dated March 27, 2008.  Per this letter, the infected Nevada patients were most likely exposed in the following manner:  “1) A clean syringe and needle were used to draw a sedative medication from a new single-use vial. 2) The sedative was administered to a hepatitis C infected patient, and backflow of blood from the patient into the syringe presumably contaminated the syringe with hepatitis C virus.  3) The needle was replaced on the syringe with a new, sterile needle, but the syringe was reused to draw additional sedative from the same vial for the same patient, presumably contaminating the vial with blood containing hepatitis C virus.  4) A clean needle and syringe were used for subsequent patients, but the contaminated vial was reused, exposing subsequent patients to hepatitis C virus.”

Because these practices had prevailed at this clinic for years, nearly 40,000 Nevada patients had to be notified by letter that they should visit their primary care provider to be tested for hepatitis C, hepatitis B, and HIV.

The same March 27, 2008 letter from the California Department of Health included a list of Safe Injection Practices, drawn from the CDC website (Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings 2007, Standard Precautions (www.cdc.gov/ncidod/dhqp/gl_isolation.html).  These Safe Injection recommendations include the following: “1) Use aseptic technique to avoid contamination of sterile injection equipment.  2) Do not administer medications from a syringe to multiple patients, even if the needle or cannula on the syringe is changed.  3) Use fluid infusion and administration sets for one patient only and dispose appropriately after use.  4) Use single-dose vials for parenteral medications whenever possible.  5) Do not administer medications from single-dose vials or ampoules to multiple patients or combine leftover contents for later use.  6) If multi-dose vials must be used, both the needle or cannula and syringe used to access the multi-dose vial must be sterile.”

Viral infections have been reported secondary to unsafe anesthesia practitioners.  A cluster of four patients with hepatitis C virus (HCV) infection was identified in a single surgery clinic (Germain JM et al, Patient-to-patient transmission of hepatitis C virus through the use of multi-dose vials during general anesthesia. Infect Control Hosp Epidemiol. 2005 Sep;26(9):789-92). Molecular characterization revealed close homology between viruses, and this cluster was deemed to be due to intra-operative unsafe injection practices by anesthesia personnel using multi-dose vials.

From this point forward, your friend’s method of administering sufentanil must be stopped. You show him the above references, and urge him to change his practice for the safety of his patients.  Other verboten procedures include:  1) Using an infusion pump to administer portions of a 60 cc syringe of propofol or remifentanyl to more than one patient, even though you change the tubing;  2) Drawing 250 micrograms of fentanyl into one syringe, and then giving 100 micrograms to one patient, and 150 micrograms to the next patient from the same syringe;  3) Using a single 20 cc vial of labetalol to give repeated and multiple doses to more than one patient, if either the needle or the syringe used to draw any dose from that vial was reused.

We’ve urged our freestanding surgery centers to cease stocking large ampoules of drugs such as 5 cc Decadron, 5 or 10 mg midazolam, 5 cc Robinul, or 20 cc labetalol.  Reuse of larger ampoules gives practitioners the opportunity to spread viral infection to more than one patient if aseptic technique is ignored.  The larger vials may save the institutions money, but the saving of pennies is trivial compared to isolating each patient from the patient(s) that preceded them.

May all your present and future intravenous injection techniques comply with CDC guidelines!

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.
