Many living things are able to fall under unfavorable conditions for living in a near-death state, but that's not it. At the same time, breathing, heart palpitations and other vital processes are so slow that they can only be detected with special equipment. This condition is called a suspended animation. And a group of scientists from the US began artificially introducing people to this state to save their lives.
To enter a person in a suspended animation
Not so long ago, a new, innovative technology was tested in the US that quickly cools patients with serious injuries to gain more time for the surgery. Physicians at the University of Maryland in Baltimore initially put people in a state of suspended animation that The Guardian reported recently at a symposium at the New York Academy of Sciences.
The process itself involves slowing the brain down to a temperature of less than 10 degrees Celsius by replacing the patient's blood with ice-cold saline. Typically, the solution is pumped directly into the aorta, the main artery that carries the blood from the heart to the rest of the body. Officially known as "Emergency Preservation and Resuscitation," this procedure is being tested on people who suffer such catastrophic injuries, threatened with deadly bleeding, and on people who have a serious heart attack and simply can not receive medical attention as quickly as possible ,
Patients who are often victims of puncture wounds, shootings or massive heart attacks usually have a chance of survival of less than 5%, says dr. Samuel Tisherman from the University of Maryland in Baltimore, one of the authors of the work. At least one patient has already completed this procedure.
Rapid cooling of the victims is said to reduce brain activity until the brain almost completely stops and slows the patient's physiology. This is sufficient to give the surgeon valuable minutes to perform an operation. One of the goals of the American study is to reduce the damage to the brain that patients often suffer from severe injuries due to blood loss or internal organ damage.

One of the complications of this procedure, however, is that the patient's cells may be damaged during warm-up after surgery to end the condition of the interrupted animation. Further experiments compare the results of 20 men and women, some of whom receive standard emergency care and some who are immersed in a suspended animation state. The test should be completed before the end of the year, but conclusions are not expected until 2020.

It is worth noting that the new technology is fundamentally different from the usual anesthetic and artificial coma. The fact is that the last two manipulations are usually done with the help of medication. Of course, there are ways to introduce artificial coma by cooling, but in this case the so-called "general cooling" of the body is applied from the outside, rather than the introduction of frozen plasma by American scientists.
Scientists have also raised the issue of interstellar travel, as the suspended animation is a near-ideal "candidate" for the immersion of astronauts for the duration of the flight. However, NASA experts believe that complete hibernation for interstellar travel is a long way off. Instead, the US Space Agency is looking for ways to put astronauts into a state of sleep rather than freeze them, slowing their metabolism as well.
