三维解剖投影联合超声多媒体展示教学方法在超声引导区域麻醉教学中的应用

摘要

Objective To evaluate the application of three-dimensional anatomical projection combined with ultrasound multimedia demonstration in the teaching of ultrasound-guided regional anesthesia.Methods The combined use of three-dimensional anatomical projection and ultrasound multimedia demonstration was analyzed using tests before and after teaching and questionnaires.Results With new software and visual techniques,this teaching method can significantly improve the recognition accuracy of ultrasonic anatomical images and widely accepted by learners.Such teaching improvement was designed to increase teaching time and decrease the number of students in a team.Conclusions This new teaching method is effective to meet the requirements of the teaching of ultrasound-guided regional anesthesia.%目的 评估三维解剖投影联合超声多媒体展示教学方法在超声引导区域麻醉教学中的应用与效果. 方法 通过对比授课前后测试结果和采用问卷调查方法对三维解剖投影联合超声多媒体展示教学方法实施效果进行分析. 结果 这种应用了新软件、新视频技术的教学方法能够显著提升超声解剖图像辨识正确率,并得到学习者的普遍认可.按内容分层次授课、增加授课时间、减少小组人数是教学改进的方向. 结论 这种新的教学方法合理、有效,适应了超声引导下区域麻醉教学的迫切性.
