Controlling pelvic bleeding in an unstable fracture starts with rapid external stabilization. A pelvic binder or external stabilization device compresses the pelvic ring, reduces pelvic volume, and tamponades venous bleeding, which often leads to a quick improvement in hemodynamics. This quick measure buys time for resuscitation and definitive hemostasis, such as angiography with embolization or surgical control if needed. Urgent laparotomy targets intraperitoneal bleeding, not pelvic bleeding, so it isn’t the immediate step here. Observing with bed rest does nothing to stop active hemorrhage in an unstable patient, making it unsafe. Internal fixation with screws is a later, definitive procedure requiring a stable patient and an operating room, not the first move to control active pelvic hemorrhage. Therefore, applying a pelvic binder/external stabilization is the best immediate action.
