小儿呼吸道感染常见病原菌及药敏结果分析

目的:了解小儿下呼吸道感染的常见病原菌及其对抗菌药物的敏感性.方法:对北京市和平里医院儿科两年来确诊治疗的156例小儿呼吸道感染患儿的痰标本进行培养及药敏试验.结果:156例标本检出致病菌98株,其中G-杆菌71株(72.4％),G+球菌23株(23.5％),真菌4株(4.1％),主要致病菌依次为肺炎克雷伯菌26株,大肠埃希菌20株.流感嗜血杆菌13株,金黄色葡萄球菌7株,肺炎链球菌5株.药敏结果显示,G-杆菌对亚胺培南均敏感,其次为头孢西丁、庆大霉素,G+球菌对万古霉素均敏感,对头孢西丁、庆大霉素、环丙沙星、阿米卡星有较高的敏感性.结论:革兰阴性杆菌为本地区小儿呼吸道感染的主要致病菌,真菌的感染率也呈上升趋势,临床上应及时检测,合理用药.

The Analysis of Pathogenic Bacteria of Pediatric Respiratory Tract Infectionin Children and Their Antibiotic Sensitivity

Objective: To study common pathogenic bacteria of pediatric respiratory tract infection in children and their antibiotic sensitivity.Methods: 156 sputum samples diagnosed as respiratory tract infection from Beijing Hepingli Hospital during two years were cultured and tested on drug sensitivity.Results: There were 98 pathogen strains in 156 samples,including 71 G-bacillus strains(72.4 %),23 G+coccus strains(23.5%) and 4 strains of fungi(4.1%).The main pathogens were Klebsiella pneumonia(26 strains),Escherichia coli(20 strains),Haemophilus influenza(13 strains),Staphylococcus aureus(7 strains) and Streptococcus pneumonia(5 strains).Drug susceptibility results showed that G-bacilli was sensitive to imipenem,followed by cefoxitin,gentamicin while G+bacteria was sensitive to vancomycin but G+bacteria was more sensitive to gentamicin,cefoxitin,ciprofloxacin and amikacin.Conclusion: Gram-negative bacilli are the main pathogens in the pediatric respiratory tract infection and the fungal infection is also an upward trend,which should be timely detected clinically and rationally used.
