Introduction: Sudden oxygen supply failure (OSF) is a life-threatening consequence that may be triggered by natural disasters. Anesthesiologists are required to manage OSF promptly in such catastrophic situations. However, the current evidence regarding the efficacy of anesthesia training for sudden OSF is insufficient. This preliminary study aimed to introduce our in-situ simulation training utilizing evaluation checklists for a sudden OSF situation during general anesthesia and to evaluate the efficacy of the training program for anesthesia providers. Methods: This is a preliminary single-center, prospective study. We developed an OSF simulation scenario utilizing evaluation checklists with key actions to manage OSF. The training session comprised four components: orientation, benchmark evaluation (pre-test) according to the checklists, a short didactic lecture, and post-lecture evaluation (post-test). The scenario comprised two steps wherein the participants were supposed to utilize different oxygen supply sources immediately after OSF (Step 1) and minimize the amount of oxygen consumption (Step 2). Results: Fifteen anesthesia providers were enrolled. The score for all anesthesia providers in the post-test was significantly higher than that in the pre-test (median 8 [IQR: 8, 8], 3 [IQR: 3, 4], P < 0.001, respectively). The successful performance rates of all anesthesia providers in one key action of all the four in Step 1 and four of all the six in Step 2 were significantly higher in the post-test than in the pre-test. Conclusions: Our in-situ training method utilizing evaluation checklists for a sudden OSF situation improved overall performance of anesthesia providers.
