IntroductionHigh-energy blunt pelvic ring injuries with hemodynamic instability are complicated by a high mortality rate (up to 32%). There is no consensus on the best management strategy for these injuries. The aim of this study was to evaluate the high-energy blunt pelvic ring injury management protocol implemented in the authors' institution.Patients And MethodsThis retrospective cohort study was performed in an academic level I trauma center. The institutional protocol incorporates urgent pelvic mechanical stabilization of hemodynamically unstable patients not responding to a pelvic belt, fluids, and transfusions. If hemodynamic instability persists, angiography ± embolization is performed. Adult patients sustaining a high-energy blunt pelvic ring injury between 2014.01.01 and 2019.12.31 were included in the study. The primary outcome was mortality at 1, 2, 30 and 60 days. The secondary outcomes were the number of packed red blood cell units transfused during the first 24 h, intensive care unit stay, and total hospitalization length of stay.Results192 high-energy blunt pelvic ring injury patients were analyzed. Of these, 71 (37%) were hemodynamically unstable, and 121 (63%) were stable. The overall in-hospital mortality of the hemodynamically unstable and stable groups was 20/71 (28.2%) and 4/121 (3.3%) respectively (p<0.001). Cumulative mortality rates for hemodynamically unstable patients were 15.5% at day 1, 16.9% at day 2, 26.8% at day 30 and 28.2% at day 60, and for hemodynamically stable patients, rates were 0% at day 1 and 2, 2.5% at day 30 and 3.3% at day 60. Unstable patients required a higher number of packed red blood cell units than stable patients during the first 24 h (5.1 vs. 0.1; p<0.001). Intensive care unit length of stay and total hospitalization duration was 11.25 and 37.4 days for unstable patients and 1.9 and 20.9 days for stable patients (p<0.001).ConclusionsFor both hemodynamically unstable and stable patients, the institutional protocol showed favorable mortality rates when compared to available literature. Comparative studies are needed to determine the management strategies with the best clinical outcome and survival.Copyright © 2022 The Author(s). Published by Elsevier Ltd.. All rights reserved.
