A team of physicians at the University of Maryland School of Medicine for the first time placed people in "suspended animation" as part of a trial that could allow healthcare professionals to identify traumatic injuries, such as a gunshot or puncture wound that would otherwise the case ends in death, according to New Scientist exceptional.
Suspended animation – or "emergency resuscitation," in medical language – involves rapidly cooling the patient's body to ten to 15 degrees Celsius (50 to 59 Fahrenheit) by replacing their blood with an ice cold salt solution.  This slows down brain activity enough to buy surgeons time – several hours ̵
This is because oxygen is no longer transported to the brain, thus stopping the production of energy. Without cooling, even five minutes without brain function can cause permanent damage.
After surgery, the patient's body warms up again and the heart is restarted.
The team was approved by the US Food and Drug Administration (FDA) to conduct the trial even without the patient's consent, as there was no alternative treatment.
Warning note: the team has not yet announced the test results – or if one of the patients has even survived the test.
Leading researcher Samuel Tisherman told New Scientist that he hopes to announce the results by the end of 2020.
"Once we can prove that it works here, we can extend the usefulness of this technique. to help patients survive that they might not otherwise, "Tisherman said.
