多酶清洗剂对器械清洗效果的观察

Cleaning Effect of Multi-enzyme Agent

目的了解多酶清洗剂对器械的清洗效果及细菌清除效果。方法将229件中等污染待洗器械随机分为对照组和实验组,分别采用常规清水浸泡清洗和加酶清洗(手工、机械),清洗后观察效果,并采样做细菌学检测。结果实验组清洗后干净的比例为96.0%,对照组为35.0%,说明加酶清洗效果优于清水浸泡清洗;实验组中手工加酶清洗后的血管钳和镊子带菌率分别为33.7%和25.5%,而清洗机加酶清洗后的血管钳和镊子带菌率均为0,说明清洗机加酶清洗剂清洗医疗器械的细菌清除率优于手工加酶清洗剂。结论清洗机加多酶清洗剂进行器械清洗,可取得满意效果。

OBJECTIVE To evaluate the medical instrument＇s cleaning effect and bacterial elimination result by using multi-enzyme cleaning agent. METHODS The total 229 pieces of moderate contaminated medical instrument were randomly divided into 2 groups： control group and experiment group. The effects after routine water immersion and processing of multi-enzyme cleaning （including hand cleaning and machineone were observed and the bacteriological examination in the sample was checked. RESULTS 96% of the medical instruments in experiment group were cleaned, while only 35% of them in control group were cleaned. It was showed the cleaning effect of multi-enzyme was better than routine water immersion. In the experiment group, the contaminated rates of blood pincers and tweezers after hand cleaning with multi-enzyme were 33.7% and 25.5%, respectively, while the contaminated rates of blood pincers and tweezers after machine cleaning with multi-enzyme were 0. It indicated that the bacterial eliminate rate of machine cleaning with multi-enzyme was higher than hand cleaning with multi-enzyme. CONCLUSIONS Multi-enzyme agents are better for medical instrument cleaning.
