Survival of trauma patients after massive red blood cell transfusion using a high or low red blood cell to plasma transfusion ratio*

OBJECTIVE: Early and aggressive treatment of trauma-associated coagulopathy through transfusion of high plasma to packed red blood cell ratios is gaining favor. Whether this strategy is associated with improved survival is unclear. We performed a systematic review to determine whether higher plasma to packed red blood cell ratios compared with lower plasma to packed red blood cell ratios were associated with a survival advantage.
