Surgeons put near-death people into suspended animation for the primary time

Suspended animation has been a longtime science-fiction dream (and typically nightmare) featured in every thing from Alien to Futurama. Now, it’s been achieved for actual by medics on the College of Maryland College of Drugs, claims a report by New Scientist.

In response to the publication, the method — which is formally referred to as emergency preservation and resuscitation (EPR) — could possibly be used on sufferers with traumatic accidents.

The EPR course of entails cooling an individual to temperatures between 50- and 59-degrees Fahrenheit, changing their blood with an ice-cold saline resolution. This halts nearly the entire affected person’s mind exercise, primarily rendering them useless. Whereas the mind can usually survive for under round 5 minutes earlier than irreversible mind injury units in, cooling the physique on this manner stops the oxygen-guzzling mobile chemical reactions. The affected person can then be moved to an working theater the place a surgical group has a few hours to patch up accidents that might in any other case show deadly. After this, the affected person may be warmed up and their coronary heart restarted.

In response to New Scientist, a affected person has already been positioned in suspended animation as a part of a trial. The outcomes of this trial will likely be introduced on the finish of 2020. No info has but been made public in regards to the variety of individuals positioned in suspended animation, or the success price of the method. The trial has the backing of the U.S. Meals and Drug Administration. The human trial went forward after the method was proven to be efficient in pigs with acute trauma.

“We felt it was time to take it to our sufferers,” Professor Samuel Tisherman mentioned. “Now, we’re doing it and we’re studying loads as we transfer ahead with the trial. As soon as we are able to show it really works right here, we are able to increase the utility of this method to assist sufferers survive that in any other case wouldn’t.”
