目的评价电子听诊器辅助肺部听诊课堂教学及床旁示教的效果.方法通过对医学生进行考核以评价课堂教学效果,将38名医学生随机分为学生实验组(n=17)和学生对照组(n=21),学生实验组应用课堂授课联合电子听诊器进行培训,学生对照组仅采用课堂授课,培训前后分别应用电子听诊器进行考核,并填写调查问卷.通过对患者进行问卷调查以评价床旁示教效果,将30名住院患者按照入组顺序平均分为患者对照组及患者实验组,患者对照组用传统听诊器实时听诊呼吸音;患者实验组使用电子听诊器存储并回放呼吸音,示教结束后记录床旁示教所用时间,并由患者填写调查问卷.结果课堂教学培训后学生实验组及学生对照组考核成绩均有显著提高,培训前两组学生考核总成绩的差异无统计学意义,培训后学生实验组考核总成绩显著优于学生对照组,其差异具有统计学意义.两组患者参与教学查房的意愿及对查房的认知差异无统计学意义,患者对照组对查房及查体时间的满意度低于患者实验组.使用电子听诊器进行床旁示教可显著缩短示教时间.结论传统听诊器在真实性方面优于电子听诊器,而后者在听诊学习、模拟考试应用方面性能更佳,应用电子听诊器辅助教学可以提高学生对肺部听诊音的辨别能力,缩短床旁示教时间,值得在临床教学中推广应用.

Objective 2 independent studies were undertaken to assess the value of electronic stethoscopes in the training of pulmonary auscultation in the setting of classroom or bedside respectively.Methods 38 medical students without clinical experience were randomized into 2 groups in the classroom training section.17 students participated in a seminar on lung sounds during which electronic stethoscopes were used to play recorded lung sounds,and others received conventional formal teaching on chest auscultation as control group.Chest auscultation skills were evaluated before and after training,and questionnaires were done to evaluate the performance of electronic stethoscope compared with traditional stethoscope.In the bedside training session,30 patients participated in bedside training using electronic or traditional stethoscopes.Time of bedside training was recorded and questionnaires were done.Results Chest auscultation skills of students in both groups were increased after training.No differences in the examination score were observed between the two groups in the preliminary test(P =0.660).However,in the post-intervention assessment,the examination score of the students who had followed the electronic stethoscope training seminar was significantly greater than that of the controls (P =0.002).The answers to a feedback questionnaire indicated that electronic stethoscope was more useful for learning and examination compared with the traditional stethoscope.Time of bedside training was shortened and patients felt more comfortable with the use of electronic stethoscopes compared with the traditional stethoscopes.Conclusions Short time training of inexperienced medical students with electronic stethoscope significantly promoted their discrimination ability of lung sounds compared to students receiving only conventional teaching.The use of electronic stethoscope could also convenience bedside training by shortening training time.
