As I was en route to the parking lot on a cold autumn night, my pager started beeping. I was a new renal fellow on call, and
this was an all-too-familiar, yet still unnerving, occurrence. The number to call back was one I didn't recognize: the OR.
When I returned the call, I learned that a heart transplant had failed with disastrous complications. The patient was hypotensive
and grossly volume overloaded. The transplant team was requesting intraoperative dialysis. Minutes later, after probing unfamiliar
corridors, I arrived at the scene.
