摘　　要：目的保证新生儿监护室键盘的清洁消毒质量,避免院内交叉感染发生。方法将四川省妇幼保健院·四川省妇女儿童医院新生儿监护室使用的21个键盘分成3组,每组采取不同方式进行清洁消毒,监测消毒后即刻、消毒后1 h、消毒后5 h菌落总数情况。结果在清洁消毒后相同时间段3种不同清洁消毒方法键盘细菌污染情况统计学分析无差异(P>0.05),相同清洁消毒方法清洁消毒后不同时间段细菌污染情况比较差异有统计学意义(P<0.05)。结论清洁消毒后使用中键盘随着使用时间延长细菌污染率增加,增加键盘清洁消毒频次能降低使用中键盘污染率。Objective To ensure the cleaning and disinfection effect of keyboard and to avoid the occurrence of nosocomial cross infection in Neonatal Intensive Care Unit. Methods About 21 keyboards used in Neonatal care unit of our hospital were divided into 3 groups,each group were cleaning and disinfection with a different ways,monitoring the total number of colony within 0 h,1 h,and 5 h after disinfection respectively. Results There were no significant differences in bacterial contamination at the same time period after cleaning and disinfection of the keyboards between the three groups（ P 〉0. 05）. There were statistical significant differences in bacterial contamination at different time points in each group（ P 〈 0. 05）. Conclusion After cleaning and disinfection,the rate of bacterial contamination was increasing with the keyboard’s using time increased,and with the increasing frequencies of clean and disinfection can reduces the contamination ratio.
