简易腹腔镜模拟器在腹腔镜模拟培训中的应用研究

Application of the original laparoscopic simulator in the laparoscopy simulation training

目的本研究拟利用自主开发的腹腔镜模拟器进行实证研究,检验简易模拟器能否在腹腔镜技能教学中起到好的效果。方法招募陆军军医大学2018级、2019级临床五年制本科学员24名,随机分为研究组与对照组,进行4周的模拟培训,每周3次,每次1学时。培训内容为基本的腹腔镜技能(fundamental laparoscopic skills,FLSs),培训前、后分别进行考核并记录成绩和完成时间,培训结束后对所有参训学员进行满意度问卷调查。采用SPSS 22.0软件进行统计学分析。结果训练前两组的完成时间与考核成绩差异无统计学意义(P>0.05)。经过4周培训后,研究组完成时间缩短10.03%,训练成绩提高35.17%;对照组完成时间缩短2.09%,训练成绩提高12.34%。组间对比研究组优于对照组;两组训练后成绩均有提升,优于训练前。问卷反馈中大部分参训者认可该模拟器,并愿意向其他学员推广。结论原创性腹腔镜模拟器用于模拟培训比传统学徒式教学起到更好的培训效果,对于腹腔镜技能教学的推广和优化有十分重要的意义。

Objective To make an empirical study on verifying whether the self-developed simple laparoscopic simulator can play a good role in the training of laparoscopic skills.Methods Twenty-four Batch 2018 and Batch 2019 undergraduates of five-year clinical medicine of the Army Medical University were recruited in this study,and they were randomly divided into a research group and a control group for 4 weeks of simulation training,3 times a week,1 class hour each time.The training content was fundamental laparoscopic skills(FLSs).Before and after the training,the assessment was performed and the results and completion time were recorded.After the training,a satisfaction questionnaire was conducted among all trainees.SPSS 22.0 was used for data statistical analysis.Results There was no statistical difference between the completion time and assessment results of the two groups before training(P>0.05).After four weeks of training,the completion time of the research group was shortened by 10.03%and the training performance increased by 35.17%;the completion time of the control group was shortened by 2.09%,and the training performance improved 12.34%.The comparison between groups found that the research group was superior than the control group,and the performance of the two groups were all improved after training.Most trainees recognized the simulator and were willing to promote it to other trainees according to the questionnaire feedback.Conclusion The original laparoscopic simulator has a better training effect on simulation training than the traditional apprenticeship teaching has,which is of great significance for the promotion and optimization of laparoscopic skills teaching.
