Additionally, nearly one in four trauma patients is coagulopathic upon arrival, making appropriate and expedient delivery of blood products and adjuncts paramount to their survival. As a result, most trauma centers have developed and maintain massive transfusion protocols (MTPs) that specify preset volumes and ratios of blood products to be rapidly available when needed. These protocols also contain standardized, efficient lines of communication between the emergency department, operating room, and blood bank. In this chapter, we will discuss the etiology of trauma-induced coagulopathy (TIC), blood typing and the implications of uncrossmatched blood transfusions, currently accepted ratios of blood products for transfusion, and possible adjuncts to blood products during massive transfusion.
