神经科重症监护病房医院感染的调查分析

目的探讨神经科重症监护病房(NICU)医院感染的发病情况、感染部位、易感因素,以有针对性地进行预防与控制医院感染的发生。方法对2005年3月-2006年2月NICU住院患者进行统计分析,并对471例患者回顾性调查研究。结果调查471例患者,其中90例发生医院感染占19.11%;医院感染部位以呼吸道(46.67%)、泌尿道(44.17%)为主;年龄>60岁、有留置导尿、呼吸道机械通气、留置深静脉导管的患者比普通患者出现医院感染的概率高,并且留置时间越长医院感染的可能性越大;患者住院时间的长短对于医院感染也有明显的差异性;性别对医院感染的相关性不明显。结论NICU医院感染的发生率远高于全院医院感染率,年龄、住院时间、侵入性操作和医用插管留置时间均是医院感染的易感因素。

Nosocomial Infection in Neuro-Intensive Care Unit

OBJECTIVE To explore the status of nosocomial infection,infection sites of patients and susceptible factors of infection in neuro-intensive care unit(NICU) in order to correspondently prevent and control the occurrence of nosocomial infection.METHODS The clinical data of 471 patients admitted to NICU from Mar 2005 to Feb 2006 were investigated retrospectively.RESULTS Out of 471 cases in one year,a total of 90 cases of nosocomial infection were found.The rate of nosocomial infection was 19.11%.Among the nosocomial infection sites,the respiratory tract was the most frequent one(46.67%).The second was urinary tract(44.17%).The patients aged of more than 60 years,or with urethral catheter,mechanical ventilation,vein intubations,or with long medical intubation suffered infection more susceptibly than other patients.The infection rate of nosocomial infection was significantly different from hospitalization group.Sex was not evidently related to nosocomial infection.CONCLUSIONS The rate of nosocomial infection in NICU is largely higher than the total rate of infection.The susceptible factors are age,long-term hospitalization,invasive operations and long medical intubation.
