Therapeutic hypothermia is commonly understood to cool the body down, slow its functioning, and give doctors more time to perform repairs.
But researchers at the Pittsburgh Medical Center plan to use hypothermia in a new and novel way -- on patients with life-threatening injuries with high blood loss, such as stabbing and gunshot wounds. The treatment involves injecting icy-cold salty water directly into the patient's heart, in an attempt to give doctors more time to do their work.
To discuss the trials, the ethical questions surrounding them, and the history of hypothermia in a medical setting, we were joined by three guests:
Do you have ethical concerns about the trials?
