Early arterial access for REBOA is related to survival outcome in trauma

Introduction Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been employed in refractory hemorrhagic shock patients. Since the optimal timing of arterial access remains unclear, we evaluated the pre-occlusion status of patients and elapsed time from the arrival to the hospital are associated with the survival outcomes in the REBOA patients. Methods From August 2011-December 2016, The DIRECT-IABO investigators registered refractory hemorrhagic shock patients undergoing REBOA from 23 hospitals in Japan. Patient characteristics, mechanism of injury, injury severity score (ISS), pre- and post-occlusion systolic blood pressure (SBP), duration of aortic occlusion, clinical time course, and survival outcome were recorded and analyzed. Binary logistic regression analysis was used with mortality and Kaplan-Meier survival analysis was conducted to demonstrate the difference between early and delayed access groups. Results Among the enrolled 207 cases, the following patients were excluded from the analysis: five since they were
