综合重症监护病房医院感染调查分析

目的探讨综合医院综合ICU感染的流行病学、病原菌分布及耐药情况，为医院感染的防治提供依据。方法采用回顾性调查方式，对2002～2003年综合ICU收治的355例患进行调查。结果医院感染发生率为29．86％(106／355)，发生2例次以上感染占33．96％(36／106)，与留置尿管相关泌尿道感染率为37．5％(6／16)，与气管切开／气管插管相关的肺部感染率84．78％(39／46)。结论综合ICU医院内感染发生率较高，与患基础疾病严重、侵入性操作多有关，而且细菌耐药性高，应合理使用抗菌药物。

Analysis of Nosocomial Infection in Collegiate Intensive Care Unit

Objective To investigate the prevalence of nosocomial infection(NI), and antibiotic resistance of pathogens in collegiate ICU. Method A retrospective study was carried out to investigate nosocomial infection in ICU during the period from 2002 to 2003. Results The overall incidence of NI was 29.86%. 33.96%of NI patients had more than one time of infection.Incidence rates of urinary catheters associated urinary tract infections and tracheotomy or tracheo spile associated pneumonias were 37 5%and 84 78%, respectively. Conclusions The patients in ICU had a high incidence rate of nosocomial infection is because these patients were seriously ill and had gone through invasive operations. Many bacteria spread in ICU are drug resistant, so appropriate antibiotics should be used carefully.
