1. THE PROBLEM OF EXTREME COMPLEXITY
Some time ago I read a case report in the Annals of Thoracic Surgery. It was, in the dry prose of a medical journal article, the story of a nightmare. In a small Austrian town in the Alps, a mother and father had been out on a walk in the woods with their three- year-old daughter. The parents lost sight of the girl for a moment and that was all it took. She fell into an icy fishpond. The parents frantically jumped in after her. But she was lost beneath the surface for thirty minutes before they finally found her on the pond bottom. They pulled her to the surface and got her to the shore. Following instructions from an emergency response team reached on their cell phone, they began cardiopulmonary resuscitation.
Rescue personnel arrived eight minutes later and took the first recordings of the girl’s condition. She was unresponsive. She had no blood pressure or pulse or sign of breathing. Her body temperature was just 66 degrees. Her pupils were dilated and unreactive to light, indicating cessation of brain function. She was gone.
But the emergency technicians continued CPR anyway. A helicopter took her to the nearest hospital, where she was wheeled directly into an operating room, a member of the emergency crewstraddling her on the gurney, pumping her chest. A surgical team got her onto a heart- lung bypass machine as rapidly as it could. The surgeon had to cut down through the skin of the child’s right groin and sew one of the desk- size machine’s silicone rubber tubes into her femoral artery to take the blood out of her, then another into her femoral vein to send the blood back. A perfusionist turned the pump on, and as he adjusted the oxygen and temperature and flow through the system, the clear tubing turned maroon with her blood. Only then did they stop the girl’s chest compressions.
Between the transport time and the time it took to plug the machine into her, she had been lifeless for an hour and a half. By the two- hour mark, however, her body temperature had risen almost ten degrees, and her heart began to beat. It was her first organ to come back.
After six hours, the girl’s core reached 98.6 degrees, normal body temperature. The team tried to shift her from the bypass machine to a mechanical ventilator, but the pond water and debris had damaged her lungs too severely for the oxygen pumped in through the breathing tube to reach her blood. So they switched her instead to an artificial- lung system known as ECMO— extracorporeal membrane oxygenation. To do this, the surgeons had to open her chest down the middle with a power saw and sew the lines to and from the portable ECMO unit directly into her aorta and her beating heart.
The ECMO machine now took over. The surgeons removed the heart- lung bypass machine tubing. They repaired the vessels and closed her groin incision. The surgical team moved the girl into intensive care, with her chest still open and covered with sterile plastic foil. Through the day and night, the intensive care unit team worked on suctioning the water and debris from her lungs with a fiberoptic bronchoscope. By the next day, her lungs had recovered sufficiently for the team to switch her from ECMO to a mechanical ventilator, which required taking her back to the operating room to unplug the tubing, repair the holes, and close her chest.
Over the next two days, all the girl’s organs recovered— her liver, her kidneys, her intestines, everything except her brain. A CT scan showed global brain swelling, which is a sign of diffuse damage, but no actual dead zones. So the team escalated the care one step further. It drilled a hole into the girl’s skull, threaded a probe into the brain to monitor the pressure, and kept that pressure tightly controlled through constant adjustments in her fluids and medications. For more than a week, she lay comatose. Then, slowly, she came back to life.
First, her pupils started to react to light. Next, she began to breathe on her own. And, one day, she simply awoke. Two weeks after her accident, she went home. Her right leg and left arm were partially paralyzed. Her speech was thick and slurry. But she underwent extensive outpatient therapy. By age five, she had recovered her faculties completely. Physical and neurological examinations were normal. She was like any little girl again.
What makes this recovery astounding isn’t just the idea that someone could be brought back after two hours in a state that would once have been considered death. It’s also the idea that a group of people in a random hospital could manage to pull off something so enormously complicated. Rescuing a drowning victim is nothing like it looks on television shows, where a few chest compressions and some mouth- to- mouth resuscitation always seem to bring someone with waterlogged lungs and a stilled heart coughing and sputtering back to life. To save this one child, scores of people had to carry out thousands of steps correctly: placing the heart- pump tubing into her without letting in air bubbles; maintaining the sterility of her lines, her open chest, the exposed fluid in her brain; keeping a temperamental battery of machines up and running. The degree of difficulty in any one of these steps is substantial. Then you must add the difficulties of orchestrating them in the right sequence, with nothing dropped, leaving some room for improvisation, but not too much.
For every drowned and pulseless child rescued, there are scores more who don’t make it— and not just because their bodies are too far gone. Machines break down; a team can’t get moving fast enough; someone fails to wash his hands and an infection takes hold. Such cases don’t get written up in the Annals of Thoracic Surgery, but they are the norm, though people may not realize it.
I think we have been fooled about what we can expect from medicine—fooled, one could say, by penicillin. Alexander Fleming’s 1928 discovery held out a beguiling vision of health care and how it would treat illness or injury in the future: a simple pill or injection would be capable of curing not just one condition but perhaps many. Penicillin, after all, seemed to be effective against an astonishing variety of previously untreatable infectious diseases. So why not a similar cure- all for the different kinds of cancer? And why not something equally simple to melt away skin burns or to reverse cardiovascular disease and strokes?
Medicine didn’t turn out this way, though. After a century of incredible discovery, most diseases have proved to be far more particular and difficult to treat. This is true even for the infections doctors once treated with penicillin: not all bacterial strains were susceptible and those that were soon developed resistance. Infections today require highly individualized treatment, sometimes with multiple therapies, based on a given strain’s pattern of anti biotic susceptibility, the condition of the patient, and which organ systems are affected. The model of medicine in the modern age seems less and less like penicillin and more and more like what was required for the girl who nearly drowned. Medicine has become the art of managing extreme complexity— and a test of whether such complexity can, in fact, be humanly mastered.
The ninth edition of the World Health Organization’s international classification of diseases has grown to distinguish more than thirteen thousand different diseases, syndromes, and types of injury— more than thirteen thousand different ways, in other words, that the body can fail. And, for nearly all of them, science has given us things we can do to help. If we cannot cure the disease, then we can usually reduce the harm and misery it causes. But for each condition
