呼吸机相关性肺炎的致病菌临床分析

Clinical analysis of pathogens in ventilator-associated pneumonia.

目的 分析机械通气的患者呼吸机相关性肺炎(VAP)的致病菌群及药敏结果。方法 对 82 例VAP患者建立人工气道的机械通气采用无菌吸痰管送检痰培养分离的108株进行药敏试验。结果 82 例检查致病菌108株,G-球菌 8 株,真菌 27 株, G- 菌 73 株,分别前 3 位的是铜绿假单胞菌(25 9%),大肠埃希菌属(17 6%),克雷伯杆菌属(8 33%),10株为多种耐药菌。结论 VAP致病菌以革兰氏阴性菌为主,防治 VAP的措施应采用并合理使用抗生素。

Objective To analysis the clinical information and sensitivity of pathogenic bacteria in ventilator associated Pneumonia(VAP).Methods In 82 VAP patients.108 strains of pathogens in ventilator associated pneumonia were classified by sputum culture and drug resistance was analyzed.Results In 82 patients,108 strains of pathogens were gram positive bacilli(8 strains).fungi(27 strains).gram-negative bacilli(73 strains).The predominane pathogens were pseudomonas aeruginosa(25.9%),Bacilluscoli(17.6%) and klebsiella pneumoniae(8.33%).10 strains were predominance of multiresistance bacilli.Conclusions To prevent treatment and reasonable apllication of antibiotics should be emphasized.
