Blood transfusions in critically ill patients – ‘freshest’ blood not necessarily the best

Source: HRB

A new clinical trial called TRANSFUSE, has found the age of transfused blood cells did not impact patient survival rates among critically ill adults. The findings end speculation that fresher blood may be superior for critically ill patients. The study, funded in Ireland by the Health Research Board also found fewer transfusion reactions, including fever, with the older blood; and in the most severely ill patients, the transfusion of older blood was associated with fewer deaths’. The trial involved 4,919 patients, at 59 centres in five countries, including Ireland. The findings are published in the New England Journal of Medicine.
