两种洗消液对护理人员手消毒效果观察

目的比较护士洗手使用快速手消毒液和洗手液两种不同手消毒剂的消毒效果。方法选取某医院120例护理人员,随机分为2组,每组各60例,1组使用快速手消毒液,另1组使用洗手液,观察2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=23.48,P〈0.01;t=20.37,P〈0.01）;洗手后2组细菌群落数比较,差异无统计学意义（t=0.02,P〉0.05）;2组合格率比较,差异无统计学意义（χ2=0.90,P〉0.05）。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=37.10,P〈0.01;t=41.30,P〈0.01）;洗手后2组细菌群落数比较,差异有统计学意义（t=7.90,P〈0.01）;2组合格率比较,差异有统计学意义（χ2=4.62,P〈0.01）。结论两种手消毒剂的消毒效果显著,但手部污染明显（带菌量≥50cfu/cm2）时,应选用洗手液洗手。

Effect evaluation of hand disinfection methods among doctors and nurses

Objective To compare the effects of two hand disinfectants, the quick hand disinfection solution and the hand sanitizer. Methods 120 medical personnel were selected randomly and divided into two groups, quick hand disinfection solution group and hand sanitizer group, each group have 60 cases. The total numbers of bacteria were observed in the two groups before and after washing hands. Results To hands carried 50cfu/cm2, the numbers of bacterial communities reduced after washing comparing those before washing, there were differences after and before washing in the quick hand disinfection solution group and the hand sanitizer group（t=33.77,P〈0.01; t=30.94,P〈0.01）;The numbers of bacterial communities had no differences in the two groups after washing（t=0.39,P〉0.05））; The qualified rates of two groups had not statistically significant（ χ2=0.90,P〉0.05））.To hands carried ≥ 50cfu/cm2, the numbers of bacterial communities reduced after washing comparing those before washing, there were differences after and before washing between the two groups（t=51.61,P〈0.01; t=54.86,P〈0.01）; The numbers of bacterial communities had differences in the two groups after washing（t=10.73,P〈0.01）; The qualified rates of two groups had statistically significant（ χ2=9.08,P〈0.01）. Conclusion The effects of two hand disinfectants have good efficacy of disinfection.The hand sanitizer should be used when hand contamination was apparent（infected ≥ 50cfu/cm2）.
