【摘要】 目的对医院重症监护室(ICU)物体表面进行采样培养,了解物体表面细菌的污染情况。方法取ICU物体表面(常规消毒前),如医务人员手表面、床头柜物体表面、门把手等共80个标本,作培养、革兰染色、生化编码鉴定,以了解ICU物体表面菌群分布。结果 80个物体表面标本,共分离出带菌件数27件,污染率33.75%,分离出细菌27株共9种,其中凝固酶阴性葡萄球菌占37.04%,金黄色葡萄球菌占3.70%,微球菌占11.11%,枯草杆菌占18.52%,洋葱伯克霍尔德菌占7.41%,鲍曼不动杆菌占3.70%,铜绿假单胞菌占3.70%,肺炎克雷伯菌占7.41%,大肠埃希菌占7.41%。结论物体表面污染是医院感染潜的不可忽视的危险因素,应提高医护人员对物体表面污染的认识度,制定好预防对策以减少和避免各种感染的发生,更好地控制医院感染。更多还原

【Abstract】 Objective To investigate bacterial contamination on ICU surface.Methods Total 80 samples were taken from ICU surface(before routine disinfection),such as hand surface of medical staff,bedside cabinet surface,door handles surface etc.Then bacterial culture,gram stain,biochemical identification code were tested for understanding the distribution of ICU surface flora.Results 27 infected samples were isolated from 80 samples,the contamination rate was 33.75%.A total of 9 kinds of bacteria,Which accounted for 37.04% of Staphylococcus epidermidis,Staphylococcus aureus accounted for 3.70%,Micrococcus accounted for 11.11%,Bacillus subtilis accounted for 18.52%,Pseudomonas cepacia accounted for 7.41%,A.baumannii accounted for 3.70%,P.aeruginosa accounted for 3.70%,K.pneumoniae accounted for 7.41%,E.coli accounted for 7.41%.Conclusion Surface contamination is a potential hospital infection risk factors these can not be ignored.Medical staff should increase awareness of surface contamination.The prevention counter measures can be taken to reduce and avoid each kind of infection,and also to control the nosocomial infection better.更多还原
