Comparison of mortality among hemorrhage-control methods performed for hemodynamically unstable patients with traumatic pelvic fractures: A multi-center study

Background: /Objective: We aimed to analyze the effects of hemorrhage control methods on the mor-tality of patients with hemodynamic instability due to pelvic fracture and investigate independent mortality risk factors in these patients.Methods: Ninety-seven pelvic bone fracture patients with hemodynamic instability who visited the emergency departments of two university hospitals over 5 years were enrolled. These patients were categorized based on 28-day mortality (survival group) and acute hemorrhage mortality (non-survival group). Forty-seven patients (48.5%) underwent pelvic angiography; 45 (46.4%), pre-peritoneal pelvic packing; and 19 (19.6%), external fixation.Results: Differences in hemorrhage control methods did not significantly affect mortality. However, there was a significant difference in mortality between the groups with and without hemorrhage control methods. Multivariate logistic regression analysis revealed that patient age, trauma and injury severity score (probability of survival), and blood transfusion amount within 24 h were independent risk factors for 28-day mortality. Meanwhile, patient age, Glasgow coma scale (GCS) score, systolic blood pressure (SBP), and blood transfusion amount within 24 h were independent risk factors for mortality due to acute hemorrhage.Conclusion: Rapid and appropriate application of hemorrhage control methods can reduce acute hemorrhage-related mortality in hemodynamically unstable patients with pelvic fractures. Moreover, none of the hemorrhage control methods were superior for the decreasing mortality rate in these patients.(c) 2022 Asian Surgical Association and Taiwan Robotic Surgery Association.

Automated summary

The study aimed to analyze the effects of hemorrhage control methods on mortality in patients with hemodynamic instability due to pelvic fracture and identify independent risk factors. The results showed that the rapid and appropriate application of hemorrhage control methods can reduce acute hemorrhage-related mortality in these patients. Additionally, none of the hemorrhage control methods were superior in reducing mortality rate.
