Hypovolemic shock secondary to hemorrhage is the most frequent indication for massive blood transfusion. Clinical scenarios in which hemorrhagic shock is encountered include trauma, operative misadventure, ruptured aortic aneurysm, massive gastrointestinal hemorrhage, and solid organ transplantation (primarily hepatic), but they are expanding to include angiointerventional and endoscopic procedures. Thus, massive transfusion may occur outside of the operating room and the surgical ICU with increasing frequency.
