Blood transfusion: the fresher the better

Victims of traffic accidents and other patients with serious injuries sometimes can not do without blood transfusion. In the study, it was found that people who poured on the "fresh" blood (not older than 28 days), the chances of survival is almost two times higher than in those who received blood from old stocks.

In the sphere of attention of researchers were 202 cases of severe injuries, the victims of which took five or more blood transfusions . Researchers found that even one unit of blood older than 28 days, doubling the number of cases of formation in patients deep venous thrombosis, and increases the possibility of death due to multiple organ failure.

Moreover, the risk of death remains up to six months after the transfusion of "old" blood. The results of this study were published on the website of the journal Critical Care. Scientists emphasize that doctors would have seriously reduced the mortality from severe injuries if transfused patients such "fresh" blood.

"Critically ill patients should be transfused" fresh "red blood cells, so this increases the chances of a favorable outcome, - says specialist intensive care pediatrician Philip Spinella of Children's Medical Center in Hartford, Conn. - Since the resources of blood, as a rule, are scarce, it is important to develop effective techniques to minimize blood loss during its transfusion.
