摘要
目的评价暖箱日常清洁消毒方法的效果,并提出可行的改进办法。方法选择某院2013年12月—2014年6月新生儿重症监护病房(NICU)30台使用中暖箱,随机分为基线组、对照组和试验组,每组10台。基线组和对照组使用常规消毒法处理,即清水和含氯消毒剂分别擦拭暖箱内外壁,试验组在日常消毒法的基础上加用强化消毒法(乙醇擦拭暖箱内壁)1次,比较各组消毒效果。结果基线组于试验第4天首次检出不合格暖箱,至第7天所有暖箱均发生了不同程度的污染,不合格标本检出率为31.43%(88/280)。对照组首次检出不合格暖箱的时间中位数为第5天,试验组首次检出不合格暖箱的中位数为第7天,两组比较,差异有统计学意义(χ2=12.38,P<0.05);试验组标本不合格率为15.36%(43/280),低于对照组的32.86%(92/280),两组比较,差异有统计学意义(χ2=23.43,P<0.05)。结论在常规消毒法的基础上,加用乙醇强化消毒能够有效提高暖箱表面消毒效果,加之其方便实用、经济安全的特点,可以作为暖箱日常消毒方法在基层医疗机构推广使用。
Objective To evaluate efficacy of routine cleaning and disinfection methods for incubators,and put forward a feasible improvement solution.Methods 30 incubators used in a neonatal intensive care unit of a hospital between December 2013 and June 2014 were chosen and randomly divided into baseline,control,and trial groups（10 incubators in each group）.Baseline group and control group were disinfected by routing disinfection method（wiping internal and external surfaces of incubators with water and chlorine-containing disinfectant）,trial group adopted intensified disinfection method（wiping internal surfaces of incubators with alcohol）on the basis of routine disinfection,disinfectant efficacy of three groups were compared.Results In baseline group,unqualified incubators were initially detected on the fourth day of monitoring,all incubators were contaminated in varying degrees on the seventh day of monitoring,the detection rate of unqualified specimens was 31.43%（88/280）.The median time for the initial detection of unqualified incubators in control group and trial group were on the fifth day and seventh day respectively,there was significant difference between two groups（χ2=12.38,P〈0.05）;The unqualified rate of trial group was significantly lower than control group（15.36%[43/280]vs 32.86%[92/280],χ2=23.43,P〈0.05）.Conclusion Intensified disinfection with alcohol on the basis of routine disinfection method can effectively improve the disinfectant efficacy of the surface of incubators,it is convenient,inexpensive and safe,and worth to be popularized in primary hospitals.
