Clinical effect of spray and swab of andoful used for skin disinfection:a comparative trial

OBJECTIVE To explore disinfection efficacy of swab and spray on skin disinfection with andoful.METHODS A total of 35 subject hands were randomly divided into swab group and spray group.The samples of before and after use in each group were collected separately and observed their disinfection effect.RESULTS The number of bacteria was(21.94±11.93) CFU/cm2 in spray group and(20.60±10.22)CFU/cm2 in swab group before disinfection,were(0.20±0.47) CFU/cm2 in spray group and(0.11±0.32)CFU/cm2 in swab group after disinfection.There was no significant difference between the two groups(all P0.05).The time of disinfection in spray group was significantly less than that in swab group(2.34±0.48)s vs(11.17±1.20)s,P0.05),however,the drying time in spray group was significantly longer than that in swab group(55.17±1.85)s vs(30.31±1.60)s,P0.05).A subject hand disinfection was used 0.5ml andoful in spray group,and was used 0.77ml andoful and two cotton buds in swab group.CONCLUSION There is equal disinfection efficacy in both spray group and swab group.Spray disinfection has short operating time,less use of disinfectant,and without use of cotton buds and so on.It will be able to replace swab disinfection,and play an important role in reducing medical waste and health care costs.
