摘要

目的

探讨支气管镜虚拟仿真训练系统在呼吸与危重症医学（pulmonary and critical care medicine，PCCM）专科规范化培训学员临床理论和技能培训中的应用。

方法

选取2018至2021年在空军军医大学西京医院参加过虚拟支气管镜培训的50名PCCM学员作为研究对象。采用自身前后对照研究，分别在培训前、培训1周和培训2周对其进行理论及操作考核，并采取调查问卷形式对培训效果进行评价。应用SPSS 23.0进行配对

检验和卡方检验。

结果

50名PCCM学员均完成了虚拟仿真支气管镜培训，培训结束后理论成绩提升[（80.0±5.2）分 vs. （92.4±3.8）分]，且参训学员在基础性操作总时间[（1 050.9±103.3）s vs.（386.4±47.7）s]、碰壁次数[（88.3±12.7）次 vs.（27.0±5.3）次]等指标方面均减少，肺泡灌洗液回收率[（27.6±7.4）% vs.（58.0±8.2）%]及活检阳性率[（19.2±13.1）% vs.（86.8±10.8）%]提高。最终成绩的学习曲线提示，培训第1周内成绩提升更快，培训第2周成绩提升趋于平缓。培训前后的调查问卷提示，虚拟仿真培训可提升学员对支气管镜检查的信心和熟练度。

结论

参训学员经过虚拟仿真支气管镜系统培训后，理论和操作水平比培训前提高。因此，虚拟仿真支气管镜训练系统对于提高PCCM学员临床支气管镜的整体培训效果具有现实意义，值得推广。

Abstract

Objective

To evaluate the role of virtual bronchoscopy intelligent system in improving the theory and operation level of bronchoscopy in pulmonary and critical care medicine (PCCM) teaching for standardized training specialists.

Methods

A total of 50 PCCM physicians who had participated in virtual bronchoscopy training in Xijing Hospital

Air Force Medical University from 2018 to 2021 were selected as research subjects. In this study

self-controlled method was adopted to evaluate the change of assessment indicators after 1 week and 2 weeks of training. Questionnaire survey was also used to evaluate the training effect. SPSS 23.0 software was used for paired

-test and Chi-square test.

Results

All the 50 PCCM physicians successfully completed the training of virtual bronchoscopy operation. The theoretical score was significantly improved after the training [(80.0±5.2) points vs. (92.4±3.8) points]. The basic operation time [(1 050.9±103.3) s vs. (386.4±47.7) s]

and the number of hitting the bronchial wall [(88.3±12.7) times vs. (27.0±5.3) times] were significantly reduced. The recovery rate of alveolar lavage fluid [(27.6±7.4)% vs. (58.0±8.2)%] and the positive rate of biopsy [(19.2±13.1)% vs. (86.8±10.8)%] were significantly increased. The learning curve of the final score indicated that the score improved more rapidly in the first week of training

and the score improved more slowly in the second week of training. Questionnaires before and after the training indicated that virtual intelligent training could significantly improve the confidence and proficiency of students in bronchoscopy.

Conclusion

Through the systematic training of virtual bronchoscopy intelligent system

the PCCM physicians have significantly improved their theoretical knowledge and operational proficiency. Therefore

the virtual bronchoscopy training system has practical significance for improving the overall training effect of clinical bronchoscopy for PCCM trainees

which is worthy of promotion.
