Cleaning Effect of Multi-enzyme Agent / 中华医院感染学杂志

ABSTRACT

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 groupscontrol 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.
