For the first time in history, doctors from the United States managed to plunge a person into controlled suspended animation

A team of doctors at the University of Maryland School of Medicine (USA) performed the first operation to put a person into a state of short-term suspended animation. This term is conditional, occurring to the patient can also be described as a state of controlled clinical death. At this time, the human body is extremely cold, and the brain actually stops working.

The details of the experiment are classified, and you should not wait for any information about its successes or failures until the end of 2020. Partly because the test subjects are not volunteers, but people in a dying state. More precisely, the team has official permission from the US authorities to apply the technique in critical cases without the consent of the patient. But how everything is organized is a mystery.

This choice of participants is quite justified, and the technique itself was developed not for hypothetical long flights into space or increasing life expectancy, but to help resuscitators. It is assumed that in a state of suspended animation, the destructive processes in the human body are greatly slowed down. And doctors have a few extra hours of time to take action, even if the patient's injuries are serious.

The main task of doctors for introducing a person into suspended animation was to stop the blood flow, for which the blood is extremely quickly pumped out of the body, simultaneously replacing it with a salt solution. It is already cooled down to 10-15 ℃ and lowers the temperature of all tissues, including the brain. There is no oxygen in the solution, the production of energy in the human body stops, the activity of organs stops, the body actually loses its vital functions. But the method is called controlled because scientists know how to then start the heart and bring a person back to life.
