A team of physicians at the University of Maryland School of Medicine has placed people in "off animation" for the first time as part of a lawsuit that may allow health care professionals to fix traumatic injuries such as a gunshot or stab wound Which would otherwise end in death, according to an exclusive New Scientist .
Suspended animation – or "resuscitation of distress," in medical care – involves quickly cooling a patient's body down to ten to 15 degrees Celsius (50 to 59 Fahrenheit) by replacing its blood with an ice-cold saline solution.  This slows the brain activity down enough to buy the surgeons time – a few hours ̵
This is because oxygen is no longer transported to the brain and thus stops energy production. Without cooling, even five minutes without brain functions can cause irreversible damage.
After the operation, the patient's body is heated again and the heart is restarted.
The team was authorized by the US Food and Drug Administration (FDA) to conduct the trial even without the patient's consent, as no alternative treatment is available.
One warning: the team has not yet announced the results of the trial – or whether any of the patients even survived the trial.
Leading Scientist Samuel Tisherman told New Scientist that he hopes to announce the results by the end of 2020.
"When we can prove that it works here, we can expand the utility of this technology to help patients to survive that otherwise would not, "Tisherman said.
