摘　　要：目的比较模拟器和传统教学方式在经胸超声心动图(TTE)采集技能培训中的效果差异。方法选取30名2020-07-01—2021-04-30在北京协和医院心内科超声心动图室轮转学习的医师,随机分为传统培训组和模拟器培训组,培训后每人独立完成1例TTE采集操作,比较两组总操作时间和超声心动图切面采集质量的差异。结果模拟器培训组完成1例TTE采集操作总时长显著短于传统培训组[(471±66)s vs(530±60)s](P<0.05)。模拟器培训组切面采集质量总评分显著高于传统培训组(42.7±2.5 vs 38.7±3.0,P<0.01),其中胸骨旁主动脉瓣短轴切面(3.9±0.9 vs 3.2±0.4,P<0.05)、心尖两腔心切面(4.0±0.8 vs 3.2±0.9,P<0.05)和胸骨上窝切面(3.8±0.8 vs 2.6±1.1,P<0.01)组间评分有显著性差异(P<0.05或P<0.01)。模拟器培训组学员满意度显著高于传统培训组(P<0.05)。结论模拟器培训有助于更高效掌握TTE图像获取技术,值得在医师技能培训中推广应用。Objective To compare the effect of simulation training and tradition training methods in the teaching of acquisition skills of transthoracic echocardiography(TTE).Methods From July 1,2020 to April 30,2021,30 doctors receiving TTE training in the department of cardiology of Peking Union Medical College Hospital were recruited and randomly divided into two groups:the tradition training group and the simulation group.After training,the view-specific transthoracic echocardiographic examination scores and the total operation time were compared between the two groups.Results The duration of the examinations on TTE acquisition in the simulation group was significantly shorter than that in the tradition training group[(471±66)s vs(530±60)s](P<0.05).The total score of the view-specific transthoracic echocardiographic examination in the simulation group was significantly higher than that in the tradition training group(42.7±2.5 vs 38.7±3.0,P<0.01),especially in the parasternal aortic short axis view(3.9±0.9 vs 3.2±0.4,P<0.05),apical two chamber view(4.0±0.8 vs 3.2±0.9,P<0.05)and superior sternal fossa view(3.8±0.8 vs 2.6±1.1,P<0.01).The satisfaction of the simulation group wassignificantly higher than that of the tradition training group(P<0.05).Conclusions The application of simulation teaching in TTE training is feasible and useful with acquired better skills in TTE image acquisition and improved student satisfaction.
