酸性氧化电位水现场消毒效果试验研究

Disinfection Effect of Acidity Electrolyzed Oxidizing Water:An Experimental Study

目的验证酸性氧化电位水的现场消毒效果。方法参照国家卫生部有关消毒规范方法对医务人员手、一般物体表面、医疗器械、消化内镜分消毒组与阳性对照组进行现场消毒试验。结果对30人次手消毒作用1 min,自然菌平均杀灭对数值为2.72;对物体表面作用5 min,自然菌平均杀灭对数值〉1.00;对使用后一般医疗器械常规清洗后浸泡消毒10 min,器械表面细菌的总平均杀灭对数值〉1.00;对使用后胃镜、肠镜常规清洗和酶洗处理后消毒3 min,各内镜细菌总数范围为0- 2 CFU/件,且均未检出致病菌;试验各组均消毒合格。结论酸性氧化电位水的现场消毒效果良好。

OBJECTIVE To confirm the clinical disinfection effect of acidity electrolyzed oxidizing water （AEOW）. METHODS According to the standards of disinfection techniques supplied by Health Ministry of China, the disinfection effect of health care worker, object surfaces and medical apparatus and instrument were investigated. RESULTS The log reduction of the bacteria on the hands, object surfaces and medical instruments were more than 1.00. The number of the bacteria on the endoscopes were 0-2 CFU per piece on average. No pathogenic bacteria were detected out. The disinfection effect of each experimental group was qualified. CONCLUSIONS The field disinfection effect of AEOW is accepted.
