WASHINGTON D.C. (WUSA9) -- There is always a medical tent near the finish line of the Boston Marathon to help take care of those runners who fall ill during the grueling 26-point-2 mile run.
This year, the doctors and nurses staffing it witnessed shocking carnage and human suffering.
Today, the New England Journal of Medicine published an account called "Under the Medical Tent at the Boston Marathon" by Dr. Sushrut Jangi.
Here's his recount of what he remembers after the bombs exploded:
"Suddenly, there was a loud sickening blast. My ears were ringing, and then, a long pause. John Anderson, a medical coordinator, took the microphone. 'Everybody stay with your patients,' he said, 'and stay calm.' Then we smelled smoke, a dense stench of sulfur- and heard a second explosion, farther off but no less frightening."
"At the tent, I stood in a crowd of doctors, awaiting victims, feeling choked by the smoke drifting along Boylston. Through the haze, the stretchers arrived; when I saw the first of the wounded, I was overwhelmed with nausea.
An injured woman- I couldn't tell if she was conscious- lay on the stretcher, her legs entirely blown off. Blood poured out of the arteries of her torso; I saw shredded arteries, veins, ragged tissue and muscle."
"Nothing had prepared me for the raw physicality of such unnatural violence. During residency, I had seen misery, but until that moment I hadn't understood how deeply a human being could suffer; I'd always been shielded from the severe anguish that is all to common in many parts of the world."
