摘要
目的了解综合监护室住院患者病原菌分布特点,探讨其易感因素和防治措施。方法以回顾性调查方法,对2002年5月-2004年5月入住医院综合监护室有明确医院感染的患者临床资料进行统计分析。结果综合监护室医院感染以革兰阴性杆菌为主占62.88%,其次是革兰阳性球菌占19.65%,真菌占17.47%;在革兰阴性杆菌中,以铜绿假单胞菌处于第1位,在革兰阳性球菌中绝大部分为金黄色葡萄球菌感染占84.44%,且均为耐甲氧西林葡萄球菌;监护室内医院感染部位多发生在下呼吸道占82.09%,其次为泌尿道感染占11.79%。结论综合监护室内感染的病原菌主要存在呼吸道,病原菌以革兰阴性杆菌为主,革兰阳性球菌均为耐甲氧西林葡萄球菌,医院感染危险因素与患者年龄、基础疾病、入住监护室的时间、呼吸机使用时间及侵入性操作等有一定的关系。
OBJECTIVE To investigate the distribution of bacteria in general ICU then discuss the susceptible factors and the treatment. METHODS A retrospective analysis of clinical information was performed on 123 patients diagnosed infection who stayed in ICU from May 2002 to May 2004. RESULTS Most of bacteria resulted in infection of general ICU were Gram-negative （62. 88 %） and then Gram-positive （ 19.65 %）. Fungal infection accounted for 17.47%. Pseudomonas aeruginosa occupied the highest percentage among Gram-negative bacteria. Most of Gram-positive bacteria were Staphylococcus aureus and all of them were MRS. The infection site in ICU focused on lower respiratory tract （89.09 %）. The second was urinary tract （11.79%）. CONCLUSIONS Most of the bacteria causing infection in general ICU locate in respiratory tract. They are mainly Gram-negative. All of the Gram-positive bacteria are MRS. The risk factors of hospital-acquired infection are related with patient＇s age, underlying disease, intensive care time, ventilation time and invasive operation.
