常用外科手消毒剂消毒效果评价

为了解外科常用手消毒剂的临床消毒效果,采用随机抽样和细菌检验方法进行了现场和实验室观察。结果,用含有效碘5000 mg/L的络合碘消毒液、含42.1 g/L或5000 mg/L的葡萄糖酸盐氯已定外科洗手液或氯己定乙醇洗手液以及含4500 mg/L醋酸氯已定与75%乙醇皮肤消毒剂等3种处理方法,按要求进行外科洗手消毒处理,均可使外科医生手上自然菌数平均减少99%以上。用含40g/L葡萄糖酸盐氯已定的外科洗手液与含5000 mg/L葡萄糖酸盐氯已定的70%乙醇消毒擦手液,按规定处理程序消毒处理后,手上自然菌数平均减少率为95.97%。结论,所用4种外科手消毒剂,进行外科医生手消毒处理,均可使手上自然菌减少率达到消毒要求;但各组消毒所需时间和费用不同。

EVALUATION OF DISINFECTION EFFICACY OF SURGICAL HAND DISINFECTANTS IN COMMON USE

In order to know the disinfection efficacy of surgical hand disinfectants in common use,random sampling and bacterial examination methods were used to carry out field and laboratory observation.Results: Surgical washing and disinfection of hands according to the requirement with 3 disinfectants,i.e.complex iodine disinfection solution containing available iodine 5000 mg/L,surgical hand-washing solution containing chlorhexidine gluconate 42.1 g/L or 5000 mg/L or chlorhexidine in ethanol hand-washing solution and skin disinfectant containing chlorhexidine acetate 4500 mg/L and 75% ethanol,reduced the natural bacterial count on surgeons' hands by over 99%.After disinfection according to specified treatment program with surgical hand-washing solution containing chlorhexidine gluconate 40 g/L and 70% ethanol disinfection hand-wiping solution containing chlorhexidine gluconate 5000 mg/L,the natural bacterial count on hands decreased by 95.97% in average.Conclusions: Disinfection of surgeons' hands with all the 4 surgical hand disinfectants can reduce the natural bacteria on hands to a level fulfilling the disinfection requirement,but the time and cost required were different for different disinfectants.
