医疗器械两种清洗消毒方法的质量分析

Quality analysis of two ways for rinsing and disinfecting medical equipment

目的:比较2种不同方法清洗医疗器械的清洗效果。方法:将回收的350件医疗器械随机分为观察组和对照组,观察组175件采用多酶清洗剂浸泡加超声波清洗机清洗,对照组175件采用人工机械清洗。结果:器械清洗洁净度目测观察组为97.71%,对照组为57.71%,光源放大镜观察组为90.85%,对照组为30.28%,差异有统计学意义(P<0.05),观察组的器械表面、关节轴和齿槽的污渍清洗阳性率均低于对照组,差异均有统计学意义(P<0.05)。结论:采用超声波加酶清洗器提高清洗质量,可有效控制医院感染。

Objective：To evaluate the cleaning effect of two different ways on rinsing and disinfecting the medical equipments.Methods：350 pieces of recycled medical equipment were randomized into the observation group and the control group equally.The observation group adopted soak cleaning methods of multi-enzyme detergent together with ultrasonic cleaner,while the control group adopted artificial mechanical cleaning.Results：By eye observation,the cleanliness of the equipment rinsing and disinfecting was 97.71% in the observation group and 57.71% in the control group,while observed by light-source magnifying glasses,the cleanliness of the equipment rinsing and disinfecting was 90.85% in the observation group and 30.28% in the control group,which were of statistical differences（P〈0.05）.The stain cleaning positive rate of the equipment surface,joint axis and cogging was lower than that of the control group,which was of statistical difference（P〈0.05）.Conclusion：The cleaning methods of multi-enzyme detergent together with ultrasonic cleaner can improve the rinsing quality and effectively control the hospital infection.
