Emergency Preservation and Resuscitation (EPR) is an experimental medical procedure where an emergency department patient is cooled into suspended animation for an hour to prevent incipient death from ischemia, such as the blood loss following a shooting or stabbing.
That page doesn’t say this is a net win or worked well at all, but it’s a difficult line of research. Not only are the first patients almost dead at the start of the process (as is always the case with high-risk of death experimental procedures), but there also is no way to know when a patient will show up.
Deep hypothermic circulatory arrest (DHCA) is a surgical technique that induces deep medical hypothermia. It involves cooling the body to temperatures between 20 °C (68 °F) to 25 °C (77 °F), and stopping blood circulation and brain function for up to one hour.
I think that’s a proven winner for some patients, but only at relatively high temperatures (“Profound hypothermia (< 14 °C) usually isn't used clinically. It is a subject of research in animals and human clinical trials”)
