Abstract: Objective To explore the teaching effect of a “one-day” training model for basic application of perioperative echocardiography for refresher anesthesiologists based on AR glasses and simulators. Methods The cardiac ultrasound teaching team of the Department of Anesthesiology at Peking Union Medical College Hospital designed a “one-day” teaching course for 60 trainees with no prior experience, based on AR glasses and simulators, covering basic applications of transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE). We collected the scores of theoretical and practical assessments before and after the training and conducted a survey on trainee satisfaction and changes in clinical behavior post-training. Statistical analysis was performed using SPSS 23.0 software. Results The theoretical knowledge scores before and after the training were 52.35±12.33 and 81.20±22.78, respectively (P＜0.05); the practical assessment scores were 30.33±10.65 and 73.96±23.15, respectively (P＜0.05). Overall satisfaction rate was 96.66% (58/60). Conclusions The “one-day” teaching model for basic application of perioperative cardiac ultrasound based on AR glasses and simulators, as an introductory training model, can help beginners quickly master the core content at the entry level and lay a solid foundation for subsequent clinical application.
