Pelvic hemorrhage is potentially lethal despite homeostatic interventions such as pre-peritoneal packing (PP), resuscitative endovascular balloon occlusion of the aorta (REBOA), surgery, and/or angioembolization. REBOA may be used as an alternative/adjunct to PP for temporizing bleeding in patients with pelvic fractures. Our study aimed to compare the outcomes of REBOA and/or PP, as temporizing measures, in blunt pelvic fracture patients. We hypothesized that REBOA is associated with worsened outcomes.
