On-site test of effect of acidic electrolyzed-oxidizing water on disinfection of hands and skin

OBJECTIVE To verify the effect of acidic electrolyzed-oxidizing water(AEOW) on the disinfection of hands and skin through the on-site test so as to provide the basis for selecting good hand antiseptic agent and skin disinfectant.METHODS Totally 30 subjects were randomly selected from the health care workers,the nurses,and the patients families.Their hands and forearm ulnar skin were disinfected by acidic electrolyzed-oxidizing water,then the hands and skin were sampled 1 minute after the action and were finally cultured to count the bacterial colony counts so as to evaluate the disinfection outcomes.At the same time,the disinfection effect was compared with the 75% ethanol′s,and the skin reactions were observed.RESULTS In the test of antiseptic handrubbing,the logarithm values of bacterial content of positive control group of AEOW and 75% ethanol were 1.95~3.83 and 1.85~3.62,respectively,and after the disinfection,the average killing logarithm values were 2.50 and 2.65,respectively.In the test of skin disinfection,the logarithm value of bacterial content of the positive control group was 1.90~4.30,and after the disinfection,the average killing logarithm values were 2.38 and 2.42,respectively.So,AEOW was qualified for the clinical disinfection,and there was no significant difference between the acidic electrolyzed oxidizing water and 75% ethanol.At the same time,the total bacterial colony counts on the hands was far less than 10 CFU/cm2 after the disinfection;the AEOW didn′t cause skin allergic reactions,while there was one case with skin allergic reactions against 75% ethanol.CONCLUSION AEOW shows good effect of disinfection of hands and skin without allergic reactions occurring,thus it is worthy to be promoted in the clinical disinfection.
