Hemolytic markers following the transfusion of uncrossmatched, cold‐stored, low‐titer, group O+ whole blood in civilian trauma patients

BACKGROUND Low‐titer group O whole blood (LTOWB) is increasingly being used in the civilian trauma setting, although there is a risk of hemolysis. This study evaluated the impact on hemolytic markers following the transfusion of 4 or more units of uncrossmatched LTOWB. METHODS Civilian adult trauma patients who received four or more units of leukoreduced group O+, low‐titer (<50 anti‐A and anti‐B), platelet‐replete uncrossmatched whole blood...
