摘　　要：目的:了解儿童感染菌和呼吸机相关性肺炎(VAP)的病原菌谱及致病相关因素。方法:对我院2002年各类送检的培养标本和31例机械通气患儿资料进行总结分析。结果:全院儿童感染细菌的构成比中G+球菌所占比例45.5%,G-杆菌占53.0%,PICU病房感染菌分布G-杆菌明显增加,占88.5%,G+球菌仅占7.4%,VAP感染菌分别以铜绿假单胞菌,鲍曼不动杆菌,真菌占前3位。结论:G-杆菌已成为ICU和VAP的优势菌群,对临床常用抗生素均有多重耐药现象。Objective. To investigate the bacterial spectrum of ventilator- associated pneumonia and children bacterial infection. Methods ：Specimens cultured for bacteria isolated from in patients with sucpectail bacterial infection and 31 cases with mechanical ventilator during 2002 were analysed. Results ：Gram positive cocci counted for 45.5 %, and gram negative bacilli counted for 53 %, while gram positive cocci counted for 7.4%, and gram negative bacilli counted for 88.5 % in PICU. The main organisms with VAP were Pseudomonas aeruginosa, Acinetobacter baumannii and fungus. Conclusion ：Gram negative bacilli have become the major pathogens in PICU and caused VAP, which put up multi - resistance to most commonly used antibiotics.
