重症监护病房鲍氏不动杆菌感染流行病学调查及控制

Epidemiology of acinetobacter baumanniiinfection in ICU and control measures

目的探讨重症监护病房(ICU)鲍氏不动杆菌肺部感染暴发流行的原因及控制措施,以减少类似医院感染事件的发生。方法采用前瞻和回顾性调查相结合的方法,对2010年10月15-31日陆续发生鲍氏不动杆菌肺部感染的7例患者,进行流行病学调查和ICU环境卫生学监测,并采取干预措施控制感染。结果 ICU泛耐药鲍氏不动杆菌感染罹患率28.0%;ICU环境存在污染,痰培养鲍氏不动杆菌与环境中分离鲍氏不动杆菌药敏试验耐药谱相似。结论 ICU环境污染导致该次鲍氏不动杆菌肺部感染暴发,环境清洁能够控制鲍氏不动杆菌的暴发流行。

OBJECTIVE To study the reason and control measures of Acinetobacter baumannii pulmonary infection outbreak in ICU,to reduce the incidence of hospital infection.METHODS Epidemiological investigations were performed for 7 patients from 15th to 31st Oct.2010,have been A.baumannii pulmonary infection and monitoring of ICU environmental Health by prospective and retrospective investigations.RESULTS The prevalence of pan-resistant A.baumannii infection in ICU was 28.0%,ICU environment were polluted,resistance spectrum from Sputum culture and environment of A.baumannii were similar.CONCLUSION The environmental pollution caused ICU A.baumannii pulmonary infection outbreaks.Clean environment to control outbreaks of A.baumannii epidemic.
