A Course on Endovascular Training for Resuscitative Endovascular Balloon Occlusion of the Aorta (ET-REBOA): A Pilot Study for Residents and Specialists
Abstract Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has emerged as a salvage technique changing the paradigm in the management of non-compressible torso hemorrhage. However, training for the REBOA procedure is rarely performed. The endovascular training for REBOA (ET-REBOA) course was conducted to develop the endovascular skills of participants. Methods: Sixteen residents and 12 specialists participated in this educational course. All participants were provided with pre-course learning materials that consisted of a lecture on the introduction of REBOA and a demonstration video clip a week before the course. The ET-REBOA course consisted of two sections: an ultrasound-guided sheath insertion on the puncture model, and a balloon manipulation on the vascular circuit model. A 13-item procedure checklist and the time required to perform the procedure were examined. Pre/post self-reported confidence score and course satisfaction questionnaire was obtained. Results: Twenty-eight participants performed the 56 REBOA procedures. Seven of 16 residents failed their first attempt. On the first attempt, the median total time for REBOA from ultrasound-guided vascular access to balloon inflation was 1139 ± 250 s in the resident group and 828 ± 280 s in the specialist group. The median shortened time for completion was 273 s in the resident group and 290 s in the specialist group. A significant decrease in procedure task time was observed between first and second attempt in the resident group (p = 0.016), specialist group (p = 0.004), and in total amongst all participants (p < 0.001). Conclusion: The ET-REBOA course significantly decreased the time taken to perform the REBOA procedure with high satisfaction of the participants. The course could be an effective curriculum for the development of endovascular skills for performing REBOA.
