If the rib fracture is thoracic, external fixation with a chest strap can be used before transporting. 3. Wound bleeding. When bleeding, a clean dressing is usually given to stop the bleeding with a pressure dressing. If it is a slightly larger blood vessel, the bleeding cannot be stopped by pressure bandaging, a ligature can be given at the proximal end of the limb to stop the bleeding. 4, burns.
