IntroductionBetween 2011 and 2014, the Combat Casualty Training Consortium research study sought to evaluate all aspects of combat casualty care, including mortality, with a special focus on the incidence and causes of potentially preventable deaths among American combat fatalities. This study identified a major training gap in critical airway management. Because of the high rate of morbidity and mortality associated with poor or incorrect airway management, an effort to address this training gap was necessary.Materials And MethodsThis experiment compared the training using the Advanced Joint Airway Management System, a novel high-fidelity airway simulator, relative to one of the most utilized simulators for endotracheal intubation (ETI) via a parallel group randomized control trial design. Before training, participants (n = 19) attempted an ETI on a cadaver using direct laryngoscopy. Performance during the attempt was recorded and scored by trained blinded raters. Participants were then randomly allocated to either novel or conventional training. Post-training, participants completed a second ETI under the same parameters. Analysis was completed via 2 × 2 mixed analysis of variance for (1) ETI Score, (2) Errors, (3) Critical Failures, and (4) Duration, across both the pre- and post-training tests and between the two groups.ResultsA priori power analysis required a total sample size of 84 participants in this experimental design. Consequently, this study is under-powered to reach statistical significance. Scores for all trainees did improve with training, yet analyses did not reveal a difference in overall ETI score between the novel and conventional training group, at baseline or at the post-training test (P = .249).ConclusionThe Advanced Joint Airway Management System simulator presents a training effect that is comparable to the conventional training model. However, given this study's small sample size, these results must be considered preliminary and further research is merited to draw firm conclusions about its impact on trainee performance. Future studies engaging larger cohorts of trainees and exploring the other capabilities of the Advanced Joint Airway Management System (cricothyroidotomy, needle chess decompression) are needed to further examine the educational potential of this novel airway management training system.© The Association of Military Surgeons of the United States 2024.
