医护人员不同手卫生方法的效果评价

Evaluation of hand-sterilizing effect with hand disinfectant and hand washing sanitizer among doctors and nurses

目的比较快速手消毒液与洗手液洗手的消毒效果,探讨适合的手卫生方法。方法选取本院100例医护人员,随机将其分为快速手消毒液组和洗手液组等两组,每组各50例。观察两组洗手前后的细菌总数。结果快速手消毒液组和洗手液组对手带菌量≥50cfu/cm2的洗手后细菌群落数均较洗手前减少,差异有统计学意义(t=54.97,P<0.01;t=52.78,P<0.01);洗手后两组细菌群落数比较,差异有统计学意义(t=9.33,P<0.01);两组合格率比较,差异有统计学意义(χ2=8.90,P<0.01)。快速手消毒液组和洗手液组对手带菌量<50 cfu/cm2的洗手后细菌群落数均较洗手前减少,差异有统计学意义(t=38.98,P<0.01;t=36.53,P<0.01);洗手后两组细菌群落数比较,差异无统计学意义(t=0.33,P>0.05);两组合格率比较,差异无统计学意义(χ2=0.10,P>0.05)。结论两种手卫生方法均消毒效果显著,但手部污染明显(带菌量≥50cfu/cm2)时,用快速手消毒液处理的合格率低于洗手液,此时应选用洗手液加流动水洗手。

Objective To compare the sterilizing effects of the hands with quick hand disinfectant and hand sanitizer among medical workers and nurses. Methods A hundred medical personnel selected were randomly divided into quick hand disinfection group and hand sanitizer group, each consisted of 50 cases. The total number of bacteria were detected, were observed in the two groups before and after washing hands. Results The numbers of bacteria on the hands of both groups were significantly reduced after washing and steriliztion （1〉 50cfu/cm2）, （ t=-54.97, P〈 0.01 ; t=-52.78, P〈 0.01 ）.The difference of bacterial colony and qualification rates in both groups after sterilizing and washing hands were all significandy（t=-9.33,P〈 0.01, X2=8.90,P〈0.01） The quantity of bacteria after sterilization and hand washing were significantly reduced （below （50cfu/ cm2, t=38.98, P〈 0.01 ; t=36.53, P〈 0.01 ）,while no significant difference in the number of bacterial colony and qualification rates was observed in both groups after washing hand with sanitizer （P〉 0.05） o .Conclusion The sterilization of methods of hand sterilization and hand sanitizere were all good, but the effect of hand sterilization was apparently better.
