OP sensitivity in the US: Blood altered with saline
It sounds a bit like science fiction, which is what doctors in the United States did for the first time: by freezing saline, they replaced the blood of a seriously injured patient so that he was clinically dead for two hours. So the doctors took the time to surgery him and save his life.
Artificial death: The body cools to 10 to 15 degrees
Professor Samuel Tisherman of the University of Maryland School of Medicine is the first physician to successfully complete this procedure with his team. He told New Scientist magazine: "It was a bit surreal." During treatment, the patient's blood is completely replaced by cold saline.
As a result, his body temperature drops to 10 to 15 degrees Celsius and the patient's "death" sets in – as a result, brain and heart activities cannot be measured. This method promises hope and great benefits especially for severely injured people who have suffered major blood loss, for example, from a gunshot wound or accident. These patients would typically have a "five percent chance of survival during surgery," Tisherman reports. However, with controlled cardiac arrest, doctors are given about two hours to complete a life-sustaining operation.
The patient was quasi-preserved and revived
A method he developed called Tishermann's "Emergency Conservation and Resuscitation" (Emergency Conservation and Resuscitation). The background is to stop the destruction of cells by cold treatment. Under normal circumstances, the first cells die within minutes of lack of oxygen. After about five minutes without oxygen, the brain is irreversibly damaged, or the damage is irreversible. This is precisely what prevented the use of ice-cold salt solution.
After surgery, saline is removed from the patient's body and replaced with blood. The patient's body warms up until the heartbeat continues. So far, this technique has only been tested on pigs. Now she has succeeded for the first time in one person. A sensational and highly promising success that gives hope for a new era of healing for the seriously injured.
