摘要
目的了解综合性重症监护病房医院感染的情况，调查感染的相关因素。方法采用前瞻性监测方法，对2008年1—6月该医院重症监护病房所有住院患者的医院感染进行监测及感染相关因素的调查。结果在6个月时间内，共监测重症监护病房入住患者175例，发生医院感染41例，46例次，感染发病率为23．43％，感染例次率为26．29％。平均病情严重程度ASIS评分为4．34分，调整病人日医院感染发病率为5．53％0。重症监护病房医院感染与气管切开关系最密切，相关感染率为51．06％；其次是动静脉插管，相关感染率为41．67％。重症监护病房病人医院感染部位以下呼吸道感染为主，病原菌分布以革兰阴性杆菌感染为主。结论医院重症监护病房住院病人是医院感染高发人群，感染部位以呼吸道为主，气管切开是重要诱发因素。
Objective To study the characteristics of nosocomial infections （NI） and investigate its related factors in integrated ICU. Methods Prospective investigation method was used to monitored NI and survey its related factors in all patients in ICU from January to June 2008. Results Of the 175 patients monitored in 6 months, 41 suffered from NI on 46 occasions, with infection rate of 23.43% and infection case -rate of 26.29%. Average severity of illness score （ASIS） was 4.34, adjusted day infection rate was 5.53‰. Tracheotomy was most closely related to NI in ICU, secondly was vascular catheter. The NI rates associated with tracheotomy and vacular catheter were 51.06% and 41.67% respectively. The main infection sites were lower respiratory tract. The bacteria detected mostly was Gram negative bacilli. Conclusions Patients in ICU are high risk group of NI, the respiratory tract was the main site, and tracheotomy was important predisposing factor.
