LOGO Hemorrhage in Pelvic Fractures…Where To Go Dr. Dora Tai

Introduction

Bleeding from Pelvic Fractures  Three bleeding sources: 1.Arteries (10-15%) 2.Low-pressure venous plexus (80-90%) 3.Fractured cancellous bone surfaces Giannoudis PV, Pape HC.

External Pelvic Stabilization 1 Reduce pelvic volume ↓ ↓ blood loss promotes tamponade effect 2 Return bony pelvic components back into apposition ↓ Haemostatic pathways to control venous bleeding 3 ↓ clot dislodgement ↓ elimination of thrombotic process ↓ consumption of clotting factors Miller PR, Moore PS, Mansell E, Meredith W, Chang MC.

CROSS-ROAD SITUATION: ANGIO or PACKING

Angiography +/- embolisation External fixationPelvic Packing Advantages Less invasive High success rate Can stop arterial bleeding Quick to perform Does not limit access to abdomen Can be placed in the AED Quick to perform Does not require special technology Stabilize patient for angiography Disadvantages/ Complications Time consuming Requires interventional radiologist Haematoma Pin site infection Nerve and vascular injuries (C-clamp) Invasive Intrapelvic infection May not be effective for treatment of arterial bleeding Removal required Suzuki T, Smith WR, Moore EE.
