支气管镜模拟诊疗训练系统在呼吸内镜医师培训中的应用探索

Application of bronchoscope simulation diagnosis and treatment training system in the training of respiratory endoscopists

目的探讨支气管镜模拟诊疗训练系统在呼吸内镜医生培训中的可行性。方法随机招募2022年3月至2022年9月期间在浙江大学医学院附属邵逸夫医院呼吸内镜中心参与PCCM培训的一年级学员作为研究对象,随机分成直接实践组、常规训练组和强化训练组三组。所有对象在入组前均接受1.5 h的理论学习。直接实践组在不接受模拟培训情况下直接进行支气管镜实践操作;常规训练组接受5次模拟培训后进行支气管镜实践操作;强化训练组接受10次模拟培训后进行支气管镜实践操作。评价研究对象准确抵达定位病灶所在的亚段支气管定位准确率,以及独立操作支气管镜抵达定位病灶所在亚段支气管需耗费的时间。结果直接实践组、常规训练组及强化训练组的定位准确率分别为33.33%,66.67%,83.33%,三组定位准确率比较,差异无统计学意义(χ^(2)=3.27,P>0.05),三组操作时间比较,差异有统计学意义(F=23.65,P<0.05),强化训练组操作时间明显短于常规训练组,差异有统计学意义(t=3.75,P<0.05)。结论支气管镜模拟诊疗训练系统可提高初学者对支气管镜学习的效率,相对目前常规培训手段,能缩短培训周期,提高培训成效。

Objective To explore the feasibility of bronchial simulation diagnosis and treatment training system in the training of respiratory endoscopists.Methods The grade one students who participated in the PCCM training at the cen⁃ter of respiratory endoscopy,Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine from March 2022 to September 2022 were randomly recruited as the research objects and randomly divided into direct practice group,routine training group and intensive training group.All subjects received 1.5 hours of theoretical learning before practice.The direct practice group performed tracheoscopy practice without receiving simulation training.The routine train⁃ing group received 5 times of simulated training and then performed tracheoscopy practice.The intensive training group re⁃ceived 10 times of simulated training and then performed tracheoscopy practice.The positioning accuracy of target arrival location and the time required for tracheal endoscopy were evaluated.Results The positioning accuracy of direct prac⁃tice group,routine training group and intensive training group were 33.33%,66.67%and 83.33%,respectively.There was no statistically significant difference in positioning accuracy among the three groups(χ^(2)=3.27,P>0.05).The difference in operating time among the three groups was statistically significant(F=23.65,P<0.05).The operating time of the inten⁃sive training group was significantly shorter than that of the routine training group,and the difference was statistically sig⁃nificant(t=3.75,P<0.05).Conclusion The bronchial simulation diagnosis and treatment training system can improve the efficiency of learning bronchoscopy for beginners.Compared with the current conventional training means,it can shorten the training period and im⁃prove the effectiveness of training.
