目的: 探讨赤峰地区小儿肺部感染支气管灌洗液细菌培养结果及药敏结果，为临床合理用药提供参
考。方法: 选取赤峰地区医院2015－01～ 2017－01 期间400 例肺部感染病人，对所有患儿进行支气管灌洗液标本
细菌培养，同时对培养出的病原菌通过全自动细菌鉴定药敏系统进行病菌鉴定及药敏试验等，观察细菌培养及
药敏试验结果。结果: 400 例患儿中，有247 例患儿的支气管灌洗液细菌培养结果显示为阳性，153 例患儿为阴
性; 在247 例患儿中分离出261 株病原菌，包括革兰阴性菌( G^‐) 、革兰阳性菌( G⁺ ) 、真菌及正常咽部菌群等; 药
敏试验显示G－菌对于氨基糖苷类、碳青霉烯类、头霉素类及喹诺酮类等抗生素比较敏感。结论: 本地区大部分
肺部感染患儿支气管灌洗液病原菌主要为革兰阴性菌，可指导临床合理使用抗生素。

Objective: Discussion Chifeng lung infection in children in bronchoalveolar lavage fluid
bacterial culture results and susceptibility results to provide reference for clinical rational drug use．
Methods: Select Chifeng district hospital between january 2015 to january 2017，400 cases of patients
with lung infection．All children with bronchial lavage specimen bacterial culture．At the same time cultivate
pathogens by automated bacteria identification system susceptibility of bacteria identification and
susceptibility tests，observation of bacterial culture and sensitivity test results．Results: 400 cases of children，
there are 247 children with bronchial lavage showed positive bacterial culture 153 patients were
negative，247 patients out of 261 Pathogenic bacteria， including G^－( gram negative bacteria) ，G⁺( grampositive
bacteria) ， fungus and pharynx of normal flora，etc; drug sensitive test showed G^－ bacteria for
aminoglycoside，penicillium carbon alkene，cephamycin and quinolone antibiotics，such as more
sensitive．Conclusion: Most lung infections in children in the region bronchoalveolar lavage fluid pathogens
mainly Gram－negative bacteria， to guide clinical rational use of antibiotics．
