呼吸机相关性肺炎11例临床分析

Clinical analysis of 11 Cases of VAP

目的:探讨ICU发生呼吸机相关性肺炎(VAP)的危险因素,病原学的特点。方法:回顾分析2004年1～12月入院ICU11例VAP患者的基础疾病,VAP发生时间,机械通气时间及病原学分布。结果:11例VAP患者痰培养分离出致病菌21株,其中主要病原菌有:铜绿假单胞菌、大肠埃希氏菌、酵母样真菌。结论:VAP的病原菌以Gˉ杆菌为主,经验性早期应用足量广谱抗菌药物可提高VAP患者治疗成功率。

Objective To explore risk factors of VAP taking place in ICU and its etiological characteristics. Method To analyse retrospectively the basic diseases of 11 hospitalized cases of VAP between Jan. and Dec, 2004, the time when VAP took place ,the prolongation of mechanical ventilation and etiological distribution. Results 21 strains of pathogens were cultured and isolated from the sputum of 11 cases of VAP. The main pathogens are verdigris psendomonas ,escherichia coli, yeast-like fungus. Conclusion Mostly G bacillus is the pathogen of VAP. Early empirical application of adequate broad-spectum antibiotics can promote the success rate of the treatment of VAP.
