Does a prehospital applied pelvic binder improve patient survival?

Abstract

Introduction: Pelvic fractures are serious and oftentimes require immediate medical attention. Pelvic binders have become a critical tool in the management of pelvic injuries, especially in the prehospital setting. Proper application of the pelvic binder is essential to achieve the desired result. This study evaluates the effectiveness of prehospitally applied pelvic binders in improving outcomes for patients with pelvic fractures.

Methods: This retrospective cohort study analyzed 66 patients with unstable pelvic ring fracture classified as AO61B or 61C, who were treated at a Level I hospital in the emergency room between January 2014 and December 2018. The ideal position for a pelvic binder was determined, and patients were divided into three sub-groups based on whether they received a pelvic binder in the ideal position, outside the optimal range, or not at all. The primary outcome measure was the survival rate of the patients.

Results: 66 trauma patients with unstable pelvic fractures were enrolled, with a mean age of 53.8 years, who presented to our ER between 2014 and 2018. The mean ISS score was 21.9, with 60.3 % of patients having a moderate to severe injury (ISS > 16 points). Pelvic binder usage did not differ significantly between patients with an ISS < or ≥ 16 points. A total of 9 patients (13.6 %) died during hospitalization, with a mean survival time of 8.1 days. The survival rate did not differ significantly between patients with or without a pelvic binder, or between those with an ideally placed pelvic binder versus those with a binder outside the ideal range. The ISS score, heart rate, blood pressure at admission, and hemoglobin level were significantly different between the group of patients who died and those who survived, indicating their importance in predicting outcomes.

Conclusion: Our study found that prehospital pelvic binders did not significantly impact patient outcomes for unstable pelvic fractures, with injury severity score (ISS) being the strongest predictor of survival. Assessing injury severity and managing blood loss remain crucial for these patients. While pelvic binders may not impact survival significantly, they still play a role in stabilizing pelvic fractures and managing blood loss.
