Transfusion
-
Massive transfusion practices have undergone several recent developments. We sought to examine institutional practices guiding hemostatic resuscitation in the setting of massive hemorrhage. ⋯ Most institutions regularly activate recently implemented MTPs for trauma and nontrauma indications; however, few use validated scoring systems for MTP activation. MTP content is highly variable. Few institutions use TEG, while most have incorporated tranexamic acid into their protocol. The lack of consistent practices underscores the need for outcome-based studies to guide transfusion practices.
