Infectious complications of extra-peritoneal pelvic packing in emergency room.

The Extra-Peritoneal Pelvic Packing (EPP) is a procedure used in emergency conditions to control pelvic hemorrhage. This procedure can be performed in Emergency Room (ER) if the patient is too unstable to be transported into the operating room (OR), with a possible increased risk of infections linked to a less sterile environment. All patients who underwent EPP from 2009 to 2018 were selected from the trauma registry. The patients were divided into two groups according to where EPP was performed (ER or OR). A Propensity Score Matching was realized. EPP was removed in all patients in the OR after obtaining hemodynamic stabilization within 24-48 h and surgical pads were sent to the laboratory for microbiological analysis. Eighty-four patients underwent EPP during the period of the study. After PSM, 26 couples of patients were selected. No differences were observed between the two groups in the development of pelvic infection. Patients managed in OR showed a higher rate of associated abdominal injuries (p = 0.027) and an increasing need for external fixation (p = 0,005) as well as an increased proportion of laparotomies (p = 0.023), orthopedic interventions (p = 0.005) and a higher systolic blood pressure on admission (p = 0.003). The EPP is a safe procedure, even when performed out of OR. The EPP in ER allows an earlier control of bleeding in patients in extremis. To minimize the risk of infection, EPP should be removed early, as soon as hemodynamics have been stabilized.
