两种洗手方法对手消毒的效果分析

The disinfection effect analysis for two kinds of hands washing methods.

目的:探讨传统的外科洗手方法与改良后的外科洗手方法对手消毒的效果影响。方法:在2009年1～6月,对参加手术的医护人员200人次分为对照组和实验组各100人次,其中每组医师、护士各50人次。传统的洗手方法设为对照组,改进后的洗手方法设为实验组,两组在手消毒后均取样培养。并对同期1060例妇科手术患者的切口感染及愈合不良率进行分析,其中属于对照组患者500例,属于实验组患者560例。结果:对照组和实验组的医护人员手细菌培养结果均为无菌生长,对照组切口感染21例,感染率4.2%,实验组切口感染25例,感染率4.46%,两组切口感染率无明显差异,且比国内及国外的医院感染率均低。结论:传统的洗手方法与改良后的洗手方法对手的消毒均能达到无菌要求,而且能缩短洗手时间,更有利于急症手术。

Objective：Discussing the different disinfection effect between the traditional and improved methods of hands washing. Methonds：From January to June,2009,taking 200 person-times medical staffs who participate in gynaecological operations as samples,100 person-times as experimental group,the other 100 person-time as contrast group. Each group includes 50 doctors and 50 nurses. The experimental group uses the traditional method to wash their hands and the contrast group uses improved method to wash their hands. Both groups take samples for bacteria culture after disinfecting their hands. And taking 1060 patients at the same term who have gynaecological operations as samples to analyze the rate of surgical incision infections and badness wound healings,500 patients of them as experimental group and other 560 patients as contrast group.Results：The bacteria culture from the medical staffs hands in both experimental group and contrast group are axenic growth. There are 23 infected cases in contrast group,with the rate 4.6%,while there are 26 infected cases in experimental group,with the rate 4.64%. There are no obvious differences between two groups for the rate of surgical incision infections,and the rate is lower than the level required by domestic and international hospital.Conclusion：Both the traditional and improved methods of hands washing can meet the requirement of sterilization,and can save the time of hand washing. It has much more advantages for emergency operations.
