In post-mortem donation, healthy organs are removed from a deceased person and transplanted to a person in need. It is important that the family of the deceased, who gives permission to do so, is sure of the death of their loved one.
Relying on doctors helps people make an informed decision about whether to allow organ removal after death, according to doctors, writes zdrave.to.
After a circulatory arrest, there is a medical possibility of postmortem donation for a short period of time between death and organ harvesting.
At the same time, it is widely believed that people often come back to life within minutes of being officially declared dead. There is relatively little scientific information on how long after cardiac arrest this is irreversible.
“We understand that there are stories of people coming back to life and they are spreading throughout the medical community.
So we really want to provide scientific evidence of the death process to dispel possible myths about humans, “said Sonny Danani of the Research Institute for Children’s Hospitals in Eastern Ontario, a co-author of the study in a comment to Gizmodo.
FIVE MINUTES AND 14 PERCENT
Since 2014, an international team of scientists has been collecting data on the signs of life the human body gives after doctors artificially stop supporting life. The study was carried out in the United States, the Czech Republic and Canada. It includes only the dying whose family members have given permission for posthumous organ donation.
In the study, the scientists tested how correct the current recommendations are: in different countries, after the death of a person, before the removal of organs, you need to wait 2-10 minutes.
There were no cases of incorrect time of death in this study. However, it turns out that the straight line of the cardiogram after death may not be completely straight.
In about 14% of the patients, the researchers found moments of electrical activity in the heart that lasted no more than a few seconds. These bursts of activity last less than four minutes and do not lead to cardiac recovery.
“Doctors and families need to be aware that this happens at 14%. But they must be prepared for the fact that this does not mean that one will come back to life,” Danani said.
The researchers concluded that their data supported the current generalized standard of waiting five minutes after death.
