A radical procedure that involves replacing a patient's blood with cold salt water could retrieve people from the brink of death, says David Robson.
“When you are at 10C, with no brain activity, no heartbeat, no blood – everyone would agree that you’re dead,” says Peter Rhee at the University of Arizona, Tucson. “But we can still bring you back.”
he isn’t exaggerating. With Samuel Tisherman, at the University of Maryland, College Park, he has shown that it’s possible to keep bodies in ‘suspended animation’ for hours at a time. The procedure, so far tested on animals, is about as radical as any medical procedure comes: it involves draining the body of its blood and cooling it more than 20C below normal body temperature.
Tisherman created headlines around the world earlier this year, when he announced that they were ready to begin human trials of the technique on gunshot victims in Pittsburgh, Pennsylvania. The first patients will have been so badly wounded that their hearts have stopped beating, meaning that this is their last hope. ” “Killing a patient to save his life” was the New York Times’ take.
