摘　　要：目的了解临床病区终末消毒前后物表暂居菌的变化情况,为医院感染防控提供依据。方法对该院所有病区终末消毒前后物表进行采样,进行标本细菌培养与鉴定,比较终末消毒前后物表细菌数量及种类的变化,以及常见临床病原菌的分布情况。结果终末消毒后物表菌落数小于10CFU/cm2的物表所占比例为63.54%,与消毒前的56.29%相比,增加了7.25个百分点。物表采样微生物检出数量下降了6.74%。消毒前后不同物表平均带菌量除床支架、被套外,其他物表均有不同程度的下降,其中水龙头是带菌量最大的物表,其次是床头柜。消毒前后病区物表微生物均以环境中常见微生物为主,包括凝固酶阴性葡萄球菌、革兰阳性菌、微球菌、不动杆菌属细菌。临床常见病原菌主要分离自脑外科(9.49%)、肝胆科(8.76%)、皮肤科(8.76%)、儿科(8.03%)、急救部(7.30%)等,病原菌暂居部位主要为床头柜(21.17%)、水龙头(18.25%)、床支架(12.41%)等。结论终末消毒可有效降低病区物表暂居菌的数量,提高病区环境卫生质量,对医院感染预防控制具有重要意义。Objective To understand the change of transient bacteria on surface in clinical ward before and after terminal disin‐fection ,provide the basis for controlling of hospital infection .Methods Surface samples were collected before and after terminal dis‐infection in infected patch of our hospital ,and then bacterial in the samples were cultured and identified .Compared changes about number and type of samples bacterial ,distribution of common clinical pathogenic bacteria before and after of the terminal disinfec‐tion .Results The surface colony number 〈 10 CFU /cm2 accounted for 63 .54% after terminal disinfection ,compared with the dis‐infection before 56 .29% ,increased 7 .25 percentage points .Surface sampling microorganism detecting rate decreased by 6 .74% . Surface average bacteria colony had different degree decreased before and after disinfection ,except the bed frame and quilt cover . Water tap ,which was the largest amount of bacteria surface ,followed by the bedside table .Before and after disinfection ,the mainly common microorganism was environment bacteria in infected patch ,including coagulase negative staphylococcus ,gram positive ba‐cilli ,Micrococcus ,Acinetobacter spp .Clinical common pathogenic bacteria mainly isolated from the department of brain surgery （9 .49% ） ,department of hepatology（8 .76% ） ,department of dermatology （8 .76% ） ,department of pediatrics （8 .03% ） ,emergency department （7 .30% ） .Pathogenic bacteria living areas were mainly the bedside table （21 .17 % ） ,water tap （18 .25% ） ,bed rest （12 .41% ） .Conclusion Terminal disinfection could effectively reduce the number of bacteria in the infected patch ,improve the ward environmental sanitation quality ,it have an important significance in the prevention of hospital infection control .
