The Big Chill.

The article focuses on the effort of clinical researchers in the U.S. to understand how mild hypothermia therapy improves survival of people experiencing cardiac arrest and other types of trauma. With the growing use of hypothermia therapy and the number of high profile failures and some safety concerns associated with therapy, several researchers are conducting studies on the technique using animal models. Among the remarkable studies on hypothermia's beneficial effect was led by emergency medicine doctor Fritz Sterz, and a 2005 study that applied mild hypothermia therapy in babies deprived of oxygen before birth. Meanwhile, the study on hypothermia's application in head injury led by neurosurgeon Guy Clifton suggests that early cooling is the key to effective hypothermia therapy.
