What is the initial management for suspected pelvic fracture with hemodynamic instability?

• A. Activate MTP, apply pelvic binder, prepare for possible surgical management.
• B. Immediate imaging only and no binder.
• C. Manage with fluids alone.
• D. Apply an external fixation device without binder.

Answer: (B)

When a patient has a suspected pelvic fracture with hemodynamic instability, the priority is rapid hemorrhage control and stabilization. The pelvis can bleed heavily, so the quickest, most effective first step is to apply a pelvic binder to compress the pelvis and reduce pelvic volume, helping to tamponade bleeding. At the same time, activate the massive transfusion protocol to rapidly replace lost blood with balanced products (red cells, plasma, platelets) and prepare for definitive control by surgery or interventional radiology if needed. Imaging in this unstable patient would unnecessarily delay critical treatment, so it should wait until the patient is stabilized. An external fixation device may be used subsequently for stabilization, but the immediate action is binder application plus resuscitation to control the bleed and restore perfusion.
