Objective To find out the risk factors in the nosocomial infections of Pseudomonas in order to reduce its occurence. Methods By a case contol epidemiologial study including 51 cases of Pseudomonas infection and 107 cases of controls during 1995~1996. Monovariate and logistic regression analyses among all variables known as risk factors during hospitalization were used, too. Results Among all 51 infections, there were 41 Ps. aeruginosa (80.4%). They were more resistant to the first and third generations of cephalosporins, but sensitive to piperacillian and norfloxacin.Microbiological surveilance of the hospital environment demonstrated that severe contamination of the connectors of oxygen inhalaters attached on the wall. Among the risk factors were : the duration of the treatment with broad spectrum antibiotics; long duration of hospitalization; sex; and pro longed application of drainage. Conclusion The nosocomial infections of Pseudomonas could be controlled and prevented. Following necessary measures were suggested: proper use of antibiotics; shortening the duration of hospitalization; proper care on using drainage; making frequent and regular microbiological surveilance of hospital environment, etc.

目的本文旨在研究影响假单胞菌院内感染发生的危险因素及防治对策,降低院内感染率。方法分析1995~1996年发生假单胞菌感染51例,对照组107例在住院期间接受检查治疗的各项资料进行监测研究,通过单因素分析和Logistic回归分析筛选。结果使用广谱抗生素时间、住院天数、性别、引流管的应用是有显著联系的因素。51例假单胞菌、铜绿假单胞菌占80.4%,并对第1代和第3头孢菌素耐药率明显增高,对氧哌嗪青霉素和氟哌酸敏感。从医院环境微生物学监测发现墙式氧气吸入器连接口污染严重也是危险因素之一。结论严格遵守抗生素使用原则,坚持环境微生物学监测,缩短住院天数,假单胞菌所引起的院内感染是可以预防的。
