目的 评价虚拟支气管镜系统在支气管镜操作考核中的应用效果。方法 采用实验对照方法,将已在广州医科大学附属第一医院完成3个月支气管镜培训的30名学员随机分为实验组和对照组,每组15人。实验组采用虚拟支气管镜系统进行支气管镜操作考核,对照组采用临床患者(事先征得同意)进行支气管镜操作考核。比较两组学员的考核成绩和考核用时。结果 实验组学员考核成绩为(64.8±7.2)分,对照组学员考核成绩为(67.6±8.4)分,其差异无统计学意义(t=-1.39,P=0.16)。实验组学员考核用时为(611.8±43.9)秒,对照组学员考核用时为(602.1±23.3)秒,其差异无统计学意义(t=0.22,P=0.82)。结论 采用虚拟支气管镜系统在支气管镜操作考核成绩和考核用时方面效果可靠,未来可以尝试更多地应用于支气管镜操作考核中,希望能够为其他单位开展支气管镜的操作考核提供参考。
Objective To evaluate the application effect of virtual bronchoscopy in bronchoscopy operation test.Methods This study used experimental control method. Thirty participants who have completed 3 months of basic bronchoscopy training course in The First Affiliated Hospital of Guangzhou Medical University were divided into two groups randomly. Experimental group were tested by virtual bronchoscopy, and control group were tested by clinical patients (with prior consent). The test scores and the time used for test of the two groups were analyzed.Results The test score of the experimental group was (64.8±7.2) points, the test score of the control group was (67.6±8.4) points, and the difference was not statistically significant(t=-1.39,P=0.16). The time used for test in experimental group was (611.8±43.9) seconds, the time used for test in control group was (602.1±23.3) seconds, and the difference was not statistically significant(t=0.22,P=0.82).Conclusions The virtual bronchoscopy is reliable for bronchoscopy operation test in test scores and in the time used for test. In the future, we can try to apply more virtual bronchoscopy in bronchoscopy operation test, and thus provide some references for other institutions to carry out bronchoscopy operation test.
