Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique that uses internal clamping of the aorta to control abdominal, pelvic, or junctional bleeding. We created a course to train military physicians in both civilian prehospital use and battlefield use. To determine the effectiveness of this training, we conducted REBOA training for French military emergency physicians. Methods: We trained 15 military physicians, organizing the training as follows: a half-day of theoretical training, a half-day of training on mannequins, a half-day on human corpses, and a half-day on a living pig. The primary endpoint was the success rate after training. We defined success as the balloon being inflated in zone 1 of a PryTime mannequin. The secondary endpoints were the progression of each trainee during the training, the difference between the median completion duration before and after training, the median post-training duration, and the median duration for the placement of the sheath introducer before and after training. Results: Fourteen of the physicians (93%) correctly placed the balloon in the mannequin at the end of the training period. During the training, the success rate increased from 73% to 93% (p = .33). The median time for REBOA after training was only 222 seconds (interquartile range [IQR] 194-278), significantly faster than before training (330 seconds, IQR 260-360.5; p = .0033). We also found significantly faster sheath introducer placement (148 seconds, IQR 126-203 versus 145 seconds, IQR 115.5 &emdash; 192.5; p = .426). Conclusion: The training can be performed successfully and paves the way for the use of REBOA by emergency physicians in austere conditions.
