摘要
目的探讨不同病区床头柜表面消毒前后细菌学监测结果与医院感染的关系及其相关分析。方法采用"棉试子倾注法"分别在消化病区、CCU病区(冠心病监护病房)及传染病区床头柜表面进行消毒前后采样,计算菌落数及进行致病菌检测。结果消毒前不同病区床头柜表面细菌总数占比:传染病区>消化病区>CCU病区;微生物占比:革兰阳性(G+)球菌(占41.41%)>革兰阳性(G+)杆菌(占33.84%)>革兰阴性(G-)杆菌(占14.14%)>真菌(占6.57%)>革兰阴性(G-)球菌(占4.04%);致病菌以金黄色葡萄球菌、大肠埃希氏菌、肺炎克雷伯氏菌、铜绿假单胞菌等为主。结论在不同病区床头柜表面消毒前后分离出的菌株与医院感染病原菌存在有同源性。因此,加强医院各个区域环境的清洁消毒,可有效预防和控制因环境污染所造成的医院感染发生。
Objective To explore the relationship between the bacteriological monitoring results and hospital infection and its related analysis to different chests＇ surface before and after disinfection. Methods The ＂cotton sub-test law＂ was adopted to get sample from chests＇ surface in Digestion ward, CCU ward and Infectious disease ward before and after disinfection. Then we calculated the number of colonies and detected pathogens. Results The total number of surface bacteria proportion before disinfection： Infectious Diseases ward was the highest of these wards. The Digestion ward was higher than the CCU ward. Microbial proportion： Gram-positive （ G ^＋ ） cocci （ accounting for 41.41 percent） 〉 Gram positive （ G^＋ ） bacteria （ accounting for 33.84 percent） 〉 Gram-negative （G-） bacilli （accounting for 14. 14 percent） 〉 Fungi （accounting for 6. 57 percent） higher 〉 Gram-negative （G-） cocci （accounting for 4. 04% ）. Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and so on were the mainly Pathogens. Conclusions It is homology between the hospital Infection strains and the strains being isolated from the cupboard in different wards after and before disinfection. Therefore, to enhance the disinfection to the hospital environment in all re- gions can effectively prevent and control environmental pollution that caused the hospital infection.
