Bacterial Infection in Patients with Ventilator-associated Pneumonia in ICU:Cause and Strategy

目的研究ICU呼吸机相关性肺炎(VAP)细菌感染原因,总结出行之有效的预防和控制对策,以减少细菌定植与污染。方法对2003年12月1日-2006年7月13日医院ICU VAP获得性细菌感染300例患者进行流行病学研究,并采取了防控对策。结果ICU VAP获得性感染病原菌多为多重耐药菌,其中G-菌占56.3%,G+菌占23.0%,真菌占13.7%。结论采取针对性的技术和方法是控制ICU VAP的重要手段,加强ICU医院感染管理及人员培训是控制ICU VAP的根本保证。

OBJECTIVE To study the cause of bacterial infection of ventilator-associated pneumonia （VAP） in intensive care unit （ICU） and summarize effective methods to prevent and control the infection. METHODS Epidemiologic study on 300 patients with VAP in ICU from Dec 1, 2003 to Jul 13, 2006. Preventing and controlling strategy was as follows. RESULTS Pathogenic bacteria of VAP in ICU mostly were multidrug-resistant ones, of which the G- were 56.3%,G^＋ were 23% and fungi were 13.7%. CONCLUSIONS To control VAP in ICU proper technique and method are important. Management of hospital infection and related training of staff in ICU are the basic way.
