A first-year medical student is climbing limestone cliffs in rural Mexico when someone comes running toward the wall: somebody is hurt. The locals know Noah Kaufman is in medical school, which apparently makes him the closest thing they have to a doctor. The patient is a teenage boy, pale with pain, his shoulder visibly out of place. Kaufman has taken gross anatomy. He has never reduced a shoulder. The nearest hospital is in Monterrey, and the boy’s family doesn’t want to go. So Kaufman lays him facedown on the tailgate of his Toyota Tundra, lets the injured arm hang over the edge, begins pulling—and feels the shoulder pop back into place. It becomes one of the first of many times Kaufman finds himself practicing medicine outside the walls of a hospital. Soon he’s answering “Is there a doctor?” during a seizure in a movie theater; years later, he’s putting IVs into passengers on transatlantic flights and walking into highway accidents before EMS arrives. In this episode of Kaufman Chronicles, Kaufman goes back to the years when he was still learning medicine but already discovering the instinct that would define his career: when something goes terribly wrong and everyone else is looking for the doctor, he steps forward.
