Resuscitative endovascular balloon occlusion of the aorta has stormed into EM literature in the past year. REBOA is a technique used in trauma for patients that are rapidly bleeding to death from injuries to their chest, abdomen or pelvis. This technique involves rapidly placing a flexible catheter into the femoral artery, maneuvering it into the aorta and inflating a balloon at its tip. This stops blood flow beyond the balloon, essentially halting any bleeding, while also stopping all blood flow distal to the balloon. Although temporizing for severe injuries, it does provide a bridge to the operating room or the angiography suite. Join the speaker in looking the controversy and the intrigue in including REBOA into your skills in the ED.
