摘要: 目的 麻醉专业住院医师规范化培训期间使用TTE模拟器行经胸超声心动(TTE)培训是否较传统视频授课效果更好。方法 用两种授课方法进行前瞻性随机对照研究,将42名麻醉专业住院医师(1~3年级)随机分为对照组(视频授课)(n=21)和试验组(TTE模拟器授课)(n=21)。授课前行笔试(时间45min)。效果评估采用课后笔试及志愿者实体TTE操作考核。操作考核包括获取正确图像及质量,解剖结构识别,获取正确图像所需时间。结果 培训前笔试分数无统计学差异。培训后测试结果试验组优于对照组:培训后笔试(43.3%±10.8% VS 52.6%±17.6%,P<0.05),操作考核获取正确图像质量(0~25分)(7.7±5.1 VS 17.1±4.8,P<0.001),解剖结构识别(0~25分)(11.0±7.3 VS 18.2±6.3;P=0.001)。结论 结果表明麻醉专业规范化培训期间TTE培训中,TTE模拟器与传统视频授课相比,前者可以使住院医师更好的掌握实际操作TTE图像获取技术及解剖结构识别。

Abstract: Objective To assess the impact of simulation-based Transthoracic Echocardiography (TTE) training versus traditional lecture-based training on basic TTE skills in anesthesiology residents; Methods In this prospective randomized study, 42 anesthesiology residents (in anesthesia clinical training years 1 to 3)were randomized to either control (n = 21) or simulation groups (n = 21) for TTE training. A standardized pretest was administered before TTE training sessions of 40 minutes each. The training session used a lecture-based video didactic in the control group or a TTE simulator in the simulation group. Comprehension in both groups was then assessed using a written post test and by performing a TTE examination on a volunteer subject. TTE examinations were graded on the ability to acquire the correct image, image quality, anatomy identification, and time required to attain proper imaging ; Results Pretest scores revealed similar knowledge among residents . The simulation group scored higher on all criteria after the training session: written post test (43.3%±10.8% VS 52.6%±17.6%,P<0.05), volunteer subject post test image quality scores (0 to 25 scale) (7.7±5.1 VS 17.1±4.8,P<0.001), anatomy identification scores (0 to 25 scale) (11.0±7.3 VS 18.2±6.3;P=0.001); Conclusion This prospective randomized study demonstrated that anesthesiology residents trained with simulation acquired better skills in TTE image acquisition and anatomy identification on volunteer subjects.
