摘要 目的 :分析早产儿发生呼吸机相关性肺炎 ( VAP)的高危因素、致病菌及药敏的特点 ,探讨防治早产儿 VAP的措施。方法 :回顾性分析 1997~ 2 0 0 1年机械通气时间≥ 48h的 66例早产儿的临床特点 ,将患儿分为 VAP及非 VAP组 ,比较两组间胎龄、出生体重、机械通气的时间、再插管及预防性抗生素使用的发生率有无差异。所有病原学分析采用气道分泌物培养。结果 :VAP的发生率为 76.8% ,VAP组上机时间明显长于非 VAP组 ,反复插管的发生率高于非 VAP组 ,差异有显著性 ;胎龄≤ 3 2 w、出生体重≤ 150 0 g的早产儿 VAP的发生率高于胎龄 >3 2 w、出生体重 >150 0 g的早产儿 ,但统计学无显著性差异 ;预防性抗生素的使用不能降低 VAP的发生率。致病菌以肺炎克雷伯杆菌、鲍曼氏不动杆菌、铜绿假单胞菌为主。结论
