<unk>  <unk>  is an experimental medical procedure where an<unk>  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.<unk>  uses hypothermia, drugs, and fluids to "buy time" for resuscitative surgery. If successful,<unk>  may someday be deployed in the field so that paramedics can suspend and preserve patients for transport.<unk>  is similar to deep hypothermic circulatory arrest (DHCA) in that hypothermia is induced. However, the purposes and procedures of<unk>  differ from DHCA. DHCA induces hypothermia to aid preplanned surgery, whereas<unk>  is an<unk>  procedure in cases where an<unk>  department patient is rapidly dying from blood loss and will not otherwise survive long enough for the patient's wounds to be stitched up. In<unk> , blood is replaced by a saline solution, and the patient is cooled into a suspended state where metabolism is slowed and brain activity ceases. This gives the surgeon perhaps an hour to close the wounds before a warming and recirculation procedure is applied. Human trials began in the 2010s. The trial procedure involves rapidly inducing profound hypothermia (10 °C) with an aortic flush in trauma victims that have suffered cardiac arrest and failed standard resuscitative efforts.
