摘　　要：目的　探讨呼吸机相关性肺炎(VAP)的病原学诊断、菌谱及致病相关因素。方法　对我院 PICU 65 例机械通气患儿资料进行总结分析,其中15例机械通气患儿同时采用两种方法获取痰培养结果比较分析。结果　VAP感染菌分别以铜绿假单胞菌,鲍曼不动杆菌,肺炎克雷伯菌占前3位。两种方法检出的病原菌差异有显著性意义(P<0.05)。结论　G-杆菌已成为机械通气和VAP患儿的优势菌群,对临床常用抗生素均有多重耐药现象。PSB和 BAL技术优于一次性无菌吸痰管从气管插管内深部吸取分泌物方法。Objective To investigate the bacterial spectrum diagnosis of ventilator-associated pneumonia. Methods Specimens cultured for bacterial isolated from 65 cases with mechanical ventilator were analysed. Results The main organisms with VAP were Pseudomonas aeruginosa,Acinetobacter baumannii and fungus. Conclusion Gram negative bacilli have become the major pathogens in cases with mechanical ventilator and causing VAP .Which put up multi-resistance to most commonly used antibiotics.The technique of BAL and PSB surpasses with that of the time has no germ inhale phlegm tube to take from the windpipe the deep department in inside absorbs the secretion method.
