摘要
目的 评估自动化软式内镜通道刷洗系统在内镜再处理中的效果。 方法 采用随机对照设计，诊疗后的内镜使用随机数字表法分为自动组和手动组，每组200条。自动组内镜清洗时采用自动化软式内镜通道刷洗系统对每个管道刷洗3次，手动组内镜清洗时洗消人员对每个管道常规手动刷洗3次。主要终点指标为内镜清洗质量合格率，次要终点指标为洗消人员刷洗内镜用时。 结果 内镜整体清洗合格率自动组为90.0%（180/200），手动组为81.0%（162/200），差异有统计学意义（χ2=6.534，P=0.011），其中，胃镜清洗合格率自动组明显高于手动组［92.0%（127/138）比81.6%（120/147），χ2=6.658，P=0.010］，肠镜清洗合格率自动组与手动组比较差异无统计学意义［85.5%（53/62）比79.2%（42/53），χ2=0.774，P=0.379］。自动组5条内镜刷洗用时（5.17±0.42）min，手动组为（9.60±0.53）min，自动组用时明显少于手动组（t=92.644，P<0.001）。 结论 自动化软式内镜通道刷洗系统相比手动刷洗，可以提高内镜的清洗合格率，提高洗消人员的工作效率，值得临床推广应用。 Objective To evaluate the effect of automated flexible endoscope channel brushing system (AFECBS) on endoscope reprocessing. Methods A prospective randomized controlled study was conducted. The used endoscopes were divided into automatic group and manual group by random number table method, 200 in each group. In the automatic group, the AFECBS was used to scrub each tube 3 times during endoscope cleaning and in the manual group, scrubbing and disinfection personnel routinely brushed each pipeline for 3 times. The primary end point was the qualified rate of endoscopic cleaning quality in the two groups, and the secondary end point was the time spent by the scrubbing and disinfection personnel on the two groups. Results The qualified rate of overall cleaning in the automatic group was 90.0% (180/200), and in the manual group was 81.0% (162/200). The qualified rate of the automatic group was higher than that of the manual group (χ2=6.534, P=0.011). The qualified rate of gastroscope cleaning in the automatic group was higher than that in the manual group [92.0% (127/138) VS 81.6% (120/147), χ2=6.658, P=0.010]. There was no significant difference in the qualified rate of colonoscope cleaning between the automatic group and the manual group [85.5% (53/62) VS 79.2% (42/53), χ2=0.774, P=0.379]. When the cleaning personnel scoured 5 endoscopes in each of the two groups, the time of the automatic group (5.17±0.42 min) was shorter than that of the manual group (9.60±0.53 min) (t=92.644, P<0.001). Conclusion Compared with manual scrubbing, AFECBS can improve the qualified rate of endoscope cleaning and the work efficiency of scrubbing and disinfection personnel, which is worthy of clinical application.
