Bringing the dead back to life with a dash of suspended animation

A new medical treatment "brings patients back from the dead."  It sounds a lot like science fiction's beloved suspended animation.  When a person is stricken by heart attack or other killing injury, a saline mix is injected into their body, Next,

[c]ooling pads are then wrapped around a patient. The body temperature is normally 98 degrees, but cooling brings it down to 92 degrees. Doctors keep it there for about 24 hours. This process is called intentional hypothermia.
