What’s the most critical technical skill for an anesthesiologist? I ask this question when I’m teaching anesthesia residents and medical students. Their most frequent answer is . . . the ability to place an endotracheal tube. This is the wrong answer. The most critical technical skill for an anesthesiologist is . . . facemask ventilation. Why?

m_1407858832

All acute medical care follows the sequence of A-B-C, or Airway, Breathing, Circulation. Control of the airway is the most important clinical priority in anesthesia care. Placement of an endotracheal tube to establish an airway is an essential skill, but at times it’s difficult or near impossible to intubate the trachea on the first attempt.

The American Society of Anesthesiologists  Difficult Airway Algorithm addresses this issue. The Algorithm recommends, “Actively pursue opportunities to deliver supplemental oxygen throughout the process of difficult airway management. Opportunities for supplemental oxygen administration include (but are not limited to) oxygen delivery by nasal cannulae, facemask, or LMA, insufflation; and oxygen delivery by facemask, blow-by, or nasal cannulae after extubation of the trachea.”

In emergency situations, maintenance of oxygen delivery by facemask can be critical.

The INTUBATION AFTER INDUCTION OF GENERAL ANESTHESIA section of the Difficult Airway Algorithm is bifurcated into two pathways. The left side is labeled FACE MASK VENTILATION ADEQUATE. The right side is labeled FACE MASK VENTILATION NOT ADEQUATE.

The left side FACE MASK VENTILATION ADEQUATE leads to a NONEMERGENCY PATHWAY algorithm. The right side FACE MASK VENTILATION NOT ADEQUATE begins with CONSIDER/ATTEMPT SGA (Supraglottic Airway), but if SGA placement is unsuccessful, the right side FACE MASK VENTILATION NOT ADEQUATE pathway leads directly to an EMERGENCY PATHWAY algorithm subtitled “Ventilation not adequate, intubation unsuccessful.”

“Ventilation not adequate, intubation unsuccessful” is a circumstance every anesthesiologist dreads, and every anesthesiologist hopes to avoid. Failure to keep a patient oxygenated can lead to hypoxia and brain death in as short a time as three minutes.

One way to spend less time on the right side of the ASA Difficult Airway Algorithm is to be expert and proficient in facemask ventilation.

In my practice, I’d estimate 1 – 2 patients out of every 100 patients, or 7 – 10 patients per year, present an unexpected difficult intubation. In my preoperative assessment I believe their intubation will be routine or only moderately difficult. After I induce general anesthesia and paralyze the patient, I find their larynx is anterior and difficult to visualize by direct laryngoscopy. In these patients in which my initial attempt(s) are unsuccessful, repeat laryngoscopies are required, and facemask ventilation between laryngoscopies to maintain oxygenation and ventilation is critical.

A second intubation attempt may involve a change in head and neck positioning, oropharangeal suctioning, or a different laryngoscope. If these modifications are unsuccessful, video laryngoscopy is indicated. A recent study in Anesthesiology showed video laryngoscopy to be the most successful technique to achieve successful tracheal intubation after failed direct laryngoscopy, with a 92% rescue rate. Video laryngoscopy is known to be associated with improved visualization of the larynx , although placement of the tube into the trachea may still require repeated attempts, requiring alteration in curve of the stylet or repositioning of the laryngoscope.

Some might argue that the use of video laryngoscopy for the first attempt at endotracheal intubation will eliminate this problem. But as described above, for difficult airways or obese patients, even video laryngoscopy can require repeated attempts because of difficulty advancing the tube into the trachea. No data exists to support that initial video laryngoscopy is safer or more effective than direct laryngoscopy when used by anesthesiologists in operating rooms.

Airway and Breathing must be maintained by facemask ventilation until an endotracheal airway or supraglottic airway is established. The manual skill of maintaining a seal between the mask and the patient’s face requires strength. The four fingers hold the caudal aspect of the mask firmly against the chin, and also serve to extend the patient’s neck. The thumb presses down on the cephalad aspect of the mask against the bridge of the nose. The right hand squeezes the ventilation bag on the anesthesia machine.

An anesthesiologist with an injured or impaired left hand is unable to safely ventilate a patient via facemask, especially an overweight patient or a patient with a beard or abnormal facial anatomy. Because of this, an anesthesiologist with an injured or impaired left hand should not be administering general anesthesia. Anesthesiologists would be wise to avoid hand or wrist injuries which could make them unemployable. Anesthesiologists would be wise to avoid falling on their outstretched hands. The pastimes of bicycle riding, skateboarding, rollerblading, climbing ladders, and rock climbing are all fraught with hand-injury danger. Should anesthesiologists avoid these activities? At the very least, anesthesiologists need to be overly careful with these activities.

Operating room practice requires anesthesiologists to perform multiple additional technical procedures, including the placement of IVs, arterial lines, central venous catheters, spinal blocks, epidural blocks, and ultrasound-guided regional nerve blocks. Each of these skills is important, but none of them are as critical as the ability to keep a patient oxygenated, first with a facemask, and second by placing an airway tube.

In a previous column, I described a case in which an anesthesiologist lost the airway on a pregnant woman following induction of general anesthesia for Cesarean section. The acute situation led to the anesthesiologist’s unrelenting focus on repeat laryngoscopies, at the expense of the facemask ventilation needed to return the oxygen saturation to a level greater than 90%. Failure to keep the patient oxygenated through repeated intubation attempts can lead to hypoxia and brain death.

The full list of the intellectual, technical, and personal qualities necessary to succeed in the profession of anesthesiology are summarized in my column On Becoming an Anesthesiologist – What Personal Characteristics are Essential.

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” 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.
