医院感染的部位及常见致病菌

Pathogenic bacteria of nosocomial infection

目的了解我院医院感染部位分布、常见致病茵及耐药情况，为控制医院感染提供理论依据。方法采用回顾性调查方法对2005-2007年全院医院感染病例进行分析。结果2005-2007年监测病人总计26970人，发生医院感染病例191例，患病率0．71％；感染部位分布，呼吸道：72．39％、泌尿道：11．98％、手术切口：10．42％；常见致病茵中白色念珠茵最多见，其次为革兰氏阴性杆菌；革兰氏阴性杆菌主要对氨苄西林、庆大霉素、头孢唑啉耐药。结论院内感染以呼吸道感染为主，主要为白色念珠菌。

Objective To observe the location and pathogenic bacteria o~ nosocomial infection and their drug resistant. Method The hospital infection cases between 2005-2007 were retrospectively analyzed. Result Of 26970 cases,there were 191 cases of hospital infection with an incidence of O. 71 %, the distribution of locations were respiratory tract （72. 390%）, urinary tract （11. 98%） and operative incision （10.42%）. The most frequent pathogenic bacteria was Blasto-myees albicans and followed by Gram-Negative bacillus. The Gram-Negative bacillus was mainly resistant to ampicillin,cidomycin and cephazoline. Conclusion The respiratory infection is most frequent in nosocomial.
