摘　　要：目的研究情景模拟法在临床医学专业本科生自动体外除颤器(automated external defibrillator,AED)教学中的效果。方法2019年9月选取安徽医科大学临床医学专业本科生148人进行AED教学,按方法不同,随机分为非情景模拟组76人与情景模拟组72人。教学前后对学生进行问卷调查。教学后摄像记录学生一次模拟除颤全过程。分析并比较两组除颤成功率和各步骤正确率、开机时间及除颤时间。结果两组学生在年龄、性别、对AED了解、培训经历和使用理念方面比较无统计学差别。教学后学生对AED了解、遇见心脏骤停(cardiac arrest,CA)想到尽快获取AED及敢于使用AED的比例比教学前均明显增加(100%比68%;99%比45%;93%比30%,均P<0.05),但两组间比较无统计学差别。情景模拟组模拟除颤成功率、AED开机、粘贴电极片以及保持合适距离的正确率要高于非情景模拟组(100%比82%;97%比45%、86%比63%、100%比90%,均P<0.05),连接电极线和按下除颤按钮正确率两组间比较没有统计学差别(100%比99%;94%比93%,均P>0.05)。情景模拟组中开机时间及除颤时间均少于非情景模拟组〔S:10(7.25,11.75)比56(14,82.5)、81.5(75.25,89.75)比104(90.5,119.25),均P<0.05)〕。结论AED教学能增进临床医学专业本科生对AED的了解,显著提升他们在遇见CA想到尽快获取AED的意识和操作自信,其中应用情景模拟法教学的学生模拟除颤表现更为优异。Objective To investigate the effect of simulation scenario in AED teaching for undergraduates in clinical medicine.Methods In September 2019,148 undergraduates in clinical medicine from Anhui Medical University were selected for AED teaching,and according to different methods,76 of them were randomly assigned to non-simulation scenario group and 72 in scenario simulation group.Before and after teaching,the students were surveyed.After teaching,each student completed an AED simulated defibrillation,and the whole process was recorded.The success rates of defibrillation,the accuracies of each step during defibrillation,the time of AED power-on and defibrillation were analyzed and compared between the two groups.Results No significant differences were showed in the aspects of age,gender,AED understanding,training experience and using conception between the two groups.After teaching,the proportion of students who knew AED,thought of getting AED as soon as possible and dared to use AED encountering cardiac arrest(CA)increased significantly compared to before teaching(100%vs.68%;99%vs.45%;93%vs.30%,all P<0.05),but no significant differences between the two groups existed.The success rates of defibrillation,the accuracies of AED power on,electrode pad paste and maintaining an appropriate distance in the simulation scenario group were higher than that of the non-simulation scenario group(100%vs.82%,97%vs.45%,86%vs.63%,100%vs.90%,all P<0.05),the success rates of electrode line connection and pressing on defibrillator button between the two groups showed no significant difference(100%vs.99%;94%vs.93%,both P>0.05).The time of AED power-on and defibrillation in the simulation scenario group were less than the non-simulation scenario group[S:10(7.25,11.75)vs.56(14,82.5),81.5(75.25,89.75)vs.104(90.5,119.25),both P<0.05].Conclusion AED teaching could improve the understanding of AED for undergraduates in clinical medicine,and significantly enhance their awareness to get AED as soon as possible and operational confidence encounte
