Adjunct techniques used to control bleeding include use of aortic cross clamping, application of a pelvic binder, rapidly expanding hemostatic sponges, and extra-peritoneal packing. Additionally, Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) can provide life-saving proximal control for patients with massive internal hemorrhage.
