摘要
目的探讨以过氧乙酸为消毒剂的全自动内镜消毒机对纤维支气管镜的消毒效果。方法将本院诊疗后污染的纤支镜380例,随机分为实验组(采用过氧乙酸为消毒剂的汇日牌WAYWIN-2000型医用全自动内镜消毒机对支气管镜消毒)和对照组(以2%戊二醛为消毒剂的传统五槽清洗消毒法),分别从内镜表面清洁度、镜身表面附着物、管道堵塞及细菌菌落检测等方面进行评价。结果实验组在内镜表面清洁度、镜身表面附着物、管道堵塞均较对照组效果好;无论是内腔采样法还是外表采样法,实验组的无菌生长例数均高于对照组;实验组≥20cfu/件的例数明显少于对照组,用内腔采样法,实验组合格率亦明显高于对照组,差异有统计学意义(P<0.05)。结论应用过氧乙酸为消毒剂的全自动内镜消毒机明显提高纤维支气管镜清洗、消毒质量,同时减轻护理人员的劳动强度,提高支气管镜的应用效率,值得推广。
Objective To investigate the disinfection effect of peroxyacetic acid for disinfectant automatic endoscopic disinfection machine to fiber bronchoscope. Methods 380 contaminated fiber bronchoscope were randomly divided into experimental group (Use Huiri WAYWIN-2000 type medical automatic endoscopic disinfection machine of peroxyacetic acid as disinfectant to bronchoscopy disinfec- tion) and control group (Use traditional five tank cleaning and disinfection method of 2% glutaraldehyde as disinfectant), and evaluated the endoscopic surface cleanliness, lens barrel surface attachment, pipe blockage and bacterial colonies detected. Results Experimental group in the endoscopic surface cleanliness, lens barrel surface attachment and pipe blockage were better than those in the control group; aseptic growth number are higher than those in the control group both intracavity sampling and appearance sampling; Colony count ≥20cfu in experimental'group was significantly less than that of the control group, the differences were statistically significant (P〈0.05). Conclusion The application of peracetic acid to automatic endoscopic disinfection machine for disinfectant significantly improve fiberoptic bronchoscopc cleaning and disinfection quality, reduce labor intensity of the nurses, and improve the efficiency of the bronchoscope.
