摘　　要：目的 麻醉专业住院医师规范化培训期间使用TIE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45 min）.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 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.Objective To assess the impact of simulation-based transthoracic echocardiography （TTE） train- ing 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 resi- dents. 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 ）. Conclusions This prospective randomized study demonstrated that anesthesiologyresidents trained with simulation acquired better skills in TTE image acquisition and anatomy identification on volunteer subjects.
