[Place of preperitoneal pelvic packing in severe pelvic traumatisms: 20 cases in a French level 1 trauma center].

Background: The overall mortality of hemodynamically unstable patients with pelvic trauma is high. Their management is controversial concerning places of arterioembolization and pelvic packing associated with pelvic stabilization. The aim of this study was to collect the pre-peritoneal pelvic packing (PPP) performed in our institution over 10years in order to propose a management algorithm.

Method: From January 2010 to December 2020, all patients with a hemodynamically unstable pelvic fracture who had PPP combined with pelvic stabilization were included. Data were collected prospectively and analyzed retrospectively. The main judgement criteria were early hemorrhage-induced mortality (<24h) and overall mortality (<30d).

Results: Twenty patients had PPP out of 287 polytrauma patients with pelvic fracture. The first-line PPP proposed in our algorithm significantly reduced the number of red blood cells (RBCs) (P=0.0231) and improved systolic blood pressure (SBP) (P<0.001) within 24hours of first-line PPP (compared with preoperative). Six patients (30%) were embolized postoperatively for active bleeding not necessarily pelvic. The overall mortality at 30days was 50% (10/20).

Conclusion: PPP is a fast, easy, effective and safe procedure for venous, bone and sometimes arterial bleeding. PPP is part of damage control surgery and we propose it as a first-line procedure. AE remains complementary in a second step.
