Clinical Impact of a Dedicated Trauma Hybrid Operating Room

Abstract

BACKGROUND: Early hemorrhage control is essential to optimal trauma care. Hybrid operating rooms offer early, concomitant performance of advanced angiographic and operative hemostasis techniques, but their clinical impact is unclear. Herein, we present our initial experience with a dedicated, trauma hybrid operating room. STUDY DESIGN: This retrospective cohort analysis of 292 adult trauma patients undergoing immediate surgery at a Level I trauma center compared patients managed after implementation of a dedicated, trauma hybrid operating room (n = 186) with historic controls (n = 106). The primary outcomes were time to hemorrhage control (systolic blood pressure >= 100 mmHg without ongoing vasopressor or transfusion requirements), early blood product administration, and complication. RESULTS: Patient characteristics were similar between cohorts (age 41 years, 25% female, 38% penetrating trauma). The hybrid cohort had lower initial hemoglobin (10.2 vs 11.1 g/dL, p = 0.001) and a greater proportion of patients undergoing resuscitative endovascular balloon occlusion of the aorta (9% vs 1%, p = 0.007). Cohorts had similar case mixes and intraoperative consultation with cardiothoracic or vascular surgery (13%). Twenty-one percent of all hybrid cases included angiography. The interval between operating room arrival and hemorrhage control was shorter in the hybrid cohort (49 vs 60 minutes, p = 0.005). From 4 to 24 hours after arrival, the hybrid cohort had fewer red cell (0.0 vs 1.0, p = 0.001) and plasma transfusions (0.0 vs 1.0, p < 0.001). The hybrid cohort had fewer infectious complications (15% vs 27%, p = 0.009) and ventilator days (2.0 vs 3.0, p = 0.011), and similar in-hospital mortality (13% vs 10%, p = 0.579). CONCLUSIONS: Implementation of a dedicated, trauma hybrid operating room was associated with earlier hemorrhage control and fewer early blood transfusions, infectious complications, and ventilator days.
