This document discusses pelvic splinting in trauma patients. It notes that pelvic fractures can cause life-threatening bleeding and loss of 6 pints of blood quickly. Existing guidelines recommend using a commercial pelvic splint for prehospital management of suspected pelvic fractures. However, some ambulance services do not have these devices. As a result, clinicians currently use makeshift alternatives like sheets or upside-down backboards, or do nothing. The document questions whether commercial splints are significantly better for managing pelvic bleeding before hospital treatment.
