93例小儿急性下呼吸道感染病原学及药敏试验结果分析

目的 为了解小儿急性下呼吸道感染病原学构成及药物敏感情况，以指导临床用药。方法 对93例急性下呼吸道感染痰培养阳性者应用K．B法进行药敏试验。结果 痰培养阳性菌中革兰阴性杆菌61株，革兰阳性球菌32株；阳性率前3位致病菌分别为大肠埃希菌（15株）、肺炎克雷伯杆菌（12株）、中间，葡萄球菌（11株）；大肠埃希菌对头孢哌酮／舒巴坦、亚胺培南、环丙沙星、头孢他啶、庆大霉素、头孢吡肟、头孢噻肟、阿莫西林／棒酸、氨曲南、头孢呋辛、氨苄西林／舒巴坦等药物的敏感率均〉70％；而肺炎克雷伯杆菌对亚胺培南、头孢哌酮／舒巴坦的敏感率高；中间葡萄球菌对头孢呋辛、亚胺培南、头孢唑林的敏感率也〉70％。结论 小儿急性下呼吸道感染病原体构成以革兰阴性杆菌为主，治疗前的痰培养值得临床重视。

Etiology and drug-Sensitivity study on 93 pediatric patients with lower respiratory tract infection

Objective To understand the etiology and drug-sensitivity in pediatric patients with acute lower respiratory tract infection,ninety-three sputum specimens were tested.Methods The drug-sensitivity testing was performed by the method of K-B.Results Gram-negative bacteria were found in 61 samples and 32 samples of gram-positive.The bacteria ranking the first three are colibacillus(15),Pneumonia Klebsiella bacterium(12)and Staphylococcus(11)respectively.The sensitive ratio of colibacillus to Cefoperazone/Sulbac...
