A group of scientists from the University of Pittsburgh, the University of Maryland and Harvard Medical School conducted a study in which they developed a way to help you survive a long space flight. To do this, experts suggest administering cold saline to the astronauts.

Before testing on humans, specialists tested the new method on pigs and dogs. The development consisted in the fact that the animals were immersed in hibernation, and the blood was replaced with cold saline, as a result of which the body temperature dropped to 10 degrees Celsius. Thus, they slept for 2 hours, after which blood was returned to their bodies. When people woke up, researchers found no brain problems in them. After a successful study with animals, the experts decided to get permission for research with humans. The trial recruited a man who had cardiac arrest and had lost half of his blood.
The experts decided to cool the patient down to 10 degrees Celsius, as a result of which the metabolism slowed down and the cells survived without oxygen. The man, who was diagnosed by doctors with an abdominal injury, had his blood replaced with cold saline and was later operated on. The patient was in a state that resembled clinical death. In 2 hours, the surgeons were able to eliminate the cause of the blood loss, and after that the man was pumped back the blood. The doctors were able to heat the patient's body to the usual temperature and started the heart. The doctors managed to save the person. Thanks to the new method, astronauts have a chance to overcome long space flights without health problems, RIA Novosti reports.
