What Flight Paramedicine Actually Taught Me About Anesthesia

The patient is on a ventilator in a rural emergency department, or about to be. The room has one physician, two nurses, and a portable monitor that alarms every time the cuff cycles. The flight crew walks in with a bag, a video laryngoscope, and the knowledge that nobody else is coming. Whatever happens to this patient's blood pressure in the next ten minutes belongs to the crew.

I did versions of that for fifteen years as a flight and critical care paramedic. Some of them were ECMO transports, where the patient's circulation ran through a pump at the foot of the stretcher. Now I am a medical student, and the operating room is where I get to watch the same drugs and the same airway done under the best conditions medicine can arrange. The overlap is bigger than I expected. So is the gap.

The tube is the easy part

Flight programs drill the mechanics of intubation hard, and for good reason. But the first thing the job teaches you is that placing the tube is rarely what hurts the patient. The induction drug blunts the sympathetic drive that was holding the pressure up. Positive pressure ventilation cuts venous return. A patient who was compensating at the door stops compensating on the stretcher.

The data agree with the folklore. The INTUBE study followed 2,964 critically ill patients intubated in ICUs, emergency departments, and wards across 29 countries. Within 30 minutes of starting the procedure, 45.2% had at least one major adverse event. The most common was cardiovascular instability, in 42.6% of patients. Severe hypoxemia occurred in 9.3%, and cardiac arrest in 3.1%.¹ Those numbers come from hospitals with every resource. In the back of an aircraft, or in a small emergency department at two in the morning, the margin is thinner.

So the flight version of airway management starts well before the laryngoscope. Is the patient as oxygenated as they are going to get? Is there a pressor drawn up or already running? Has the volume status been addressed? Does this patient need a tube in the next five minutes, or in the next twenty, after the pressure is better? The phrase crews repeat to each other is "resuscitate before you intubate." It sounds like a slogan until you watch someone arrest on induction because nobody asked those questions.

One look, one pass

The second lesson is that every extra attempt costs something. In a four-year review of 1,828 emergency department intubations, adverse events occurred in 14.2% of patients intubated on the first attempt and in 47.2% of patients who needed two. By three attempts it was 63.6%.² In the field you feel those numbers before you can quote them: the saturation that drifts on the second look, the bradycardia that starts on the third.

That is why so much of my teaching time went into the procedures nobody gets to practice on real patients often enough. I ran skills fairs and simulation labs for years: surgical airways, pericardiocentesis, chest tubes. The point was never that every crew member would do a cricothyrotomy every month. The point was that the one time it mattered, the first attempt would be a rehearsed one.

What the operating room adds

Anesthesiology runs the same physiology on purpose. The patient is usually fasted, monitored, and optimized days in advance. Preoxygenation is done properly because there is time to do it properly. The induction is titrated against a pressure that is measured continuously, often through an arterial line placed before anything is pushed. The airway plan has a second and third option written down before the first is attempted.

Watching that from the head of the bed, I recognize the same priorities the flight crew had, carried out with more time, more monitoring, and deeper pharmacology. What I did not have in the field is what the OR teaches next: how an anesthetic is maintained for hours, how the ventilator is used as a treatment rather than a bridge, how fluids and pressors are managed against a surgical field that is losing blood in real time. Prehospital medicine taught me how to get a sick patient through the first ten minutes. The operating room is teaching me what comes after them.

What carries over

Three habits came with me from the aircraft, and so far none of them has needed unlearning.

Say the plan out loud before the drugs go in. Flight crews do a verbal checklist because a two-person team cannot afford a silent assumption. Good anesthesia teams do the same thing with different words.

Know what the blood pressure will do before it does it. The shock index on arrival, the trend over the last ten minutes, the drug you are about to give: those predict the next five minutes better than any single reading.

Decide where the patient ends up before you start. In the field that means the receiving hospital. In the OR it means the recovery room or the ICU. The plan for the end changes what you do at the beginning.

The patient in that rural emergency department eventually reaches an ICU, and somebody there takes the handoff. For fifteen years that handoff was the end of my part. In medical school I am finally following patients past it.
