Immediate management for open-book pelvic fracture with shock?

• A. Apply pelvic binder and stabilize pelvis; consult orthopedics
• B. Start diuretics and Trendelenburg
• C. Administer high-dose IV contrast and CT
• D. Start heparin anticoagulation and discharge

Answer: (C)

Rapid localization of bleeding sources in a hemodynamically unstable pelvic fracture enables targeted hemorrhage control. Open-book pelvic injuries often bleed from pelvic vessels, so knowing exactly where the bleed is allows for precise, definitive treatment, such as embolization or prompt surgical planning. Administering contrast-enhanced CT (CT angiography) is the fastest, most informative way to visualize pelvic vasculature and identify arterial sources of bleeding and other injuries, guiding the next lifesaving intervention. While external stabilization (like a pelvic binder) remains important to reduce pelvic volume and ongoing bleeding, the imaging step provides actionable information that directly directs how to achieve rapid hemostasis. The other options don’t address the bleeding source or hemostasis: diuretics and position changes don’t control hemorrhage; delaying imaging for treatment decisions risks ongoing blood loss; anticoagulation would worsen bleeding and discharge is inappropriate in shock.
