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 improvise with other methods like an upside-down neck brace or wrapping the patient in a sheet, but the effectiveness of these improvised methods is unclear compared to commercial splints. The document questions if appropriate prehospital splinting could minimize catastrophic bleeding from pelvic fractures.
