摘要
为更有效地清洗内镜管道,本研究采用一种新型双头内镜清洗刷。收集2019年6月—2020年8月在上海交通大学医学院附属瑞金医院消化内镜中心使用后的肠镜130件,以肠镜使用结束后清洗顺序标记为单双号,单号为常规组(n=65),采用常规单头内镜清洗刷往返式清洗;双号为实验组(n=65),采用新型双头内镜清洗刷单向式清洗,其头端为尼龙刷头,尾端为致密无纺布刷头。两组清洗方法均按照《软式内镜清洗消毒技术规范WS507—2016》进行,采用三磷酸腺苷(ATP)生物荧光检测法和细菌定量检测法对两种方法清洗软式内镜管道的效果做出评价。结果显示实验组、常规组清洗刷清洗内镜管道前后ATP相对光单位值(relative light unit,RLU)水平均有所下降[530.63 RLU(26~3559 RLU)比270.87 RLU(20~1415 RLU)],2组间比较差异有统计学意义(Z=-2.894,P<0.05)。刷洗后新型双头刷的无纺布刷头带出细菌阳性率为86.2%(56/65),尼龙刷头带出细菌阳性率为46.2%(30/65),常规单头刷的尼龙刷头带出细菌阳性率为32.3%(21/65),3组间比较差异有统计学意义(χ^(2)=41.046,P<0.05)。使用新型双头内镜清洗刷对软式内镜的清洗效果比常规单头内镜清洗刷的清洗效果更佳,无纺布刷头带出细菌效果明显优于尼龙刷头。
In order to clean the endoscopic tube more effectively,a new double-headed endoscopic cleaning brush was used in this study.A total of 130 colonoscopies were selected from the Digestive Endoscopy Center of Ruijin Hospital,Shanghai Jiao Tong University School of Medicine from June 2019 to August 2020.The colonoscopy cleaning sequence was marked with odd and even number.Colonoscopies marked with the odd number were assigned to the conventional group(n=65)which received back and forth cleaning with the single-headed endoscope cleaning brush.Colonoscopies marked with the even number were assigned to the experimental group(n=65)which received one-way cleaning with a nylon brush at the head and a dense non-woven brush at the tail.The cleaning methods for endoscopes were in accordance with Flexible Endoscopic Cleaning and Disinfection Technical Specification WS507—2016.ATP bioluminescence tests and bacterial quantitative cultures were applied to evaluate the cleaning effects of the two methods.The results showed that ATP relative light unit(RLU)decreased in both the experimental group and the conventional group[530.63 RLU(26-3559 RLU)VS 270.87 RLU(20-1415 RLU)]before and after cleaning the endoscope tube,showing significant difference between the two groups(Z=-2.894,P<0.05).After scrubbing,the positive rate of bacterial culture on the brush head was 86.2%(56/65)for the double-headed non-woven brush head,46.2%(30/65)for the double-headed nylon brush head and 32.3%(21/65)for the single-headed nylon brush head with significant differences among the three groups(χ^(2)=41.046,P<0.05).The cleaning effect of the new double-headed endoscopic cleaning brush is better than that of the conventional single-headed endoscopic cleaning brush for soft endoscope cleaning.Non-woven brush is better than nylon brush in eliminating bacteria.
