社区获得性肺炎患儿年龄与感染病原菌情况差异分析

Analysis of the difference between the age and the infection pathogens in sick children with community acquired pneumonia

目的了解我院社区获得性肺炎患儿中不同年龄段患儿易感的病原菌种类及其药物敏感情况。方法针对我院近3年社区获得性肺炎住院患儿痰培养常见病原菌,统计分析患儿各年龄阶段感染的病原菌种类的差异。结果 430例患儿痰培养结果中,大肠埃希菌占32.3%,肺炎克雷伯菌占20.2%,肺炎链球菌占14.8%,流感嗜血杆菌占13.2%,金黄色葡萄球菌占13%,阴沟肠杆菌占7.2%。各年龄组患儿感染率的高低及感染病原菌的百分比因年龄不同而异。结论在痰培养及药敏结果出来之前,可根据不同年龄段患儿易患病原菌的百分比,有针对性地选择敏感抗生素治疗。

Objective To understand the situation of the various types of pathogens and the drug sensitivity in different ages of children who were infected with community acquired pneumonia in our hospital. Methods According to the study on the sputum culture of common pathogenic bacteria in children who sufferred from community acquired pneumonia in our hospital in recent three years, the percentage of infection pathogens in the children in every age grade was analyzed statistically. Results Among the 430 sputum culture cases of sick children, the pathogenic bacteria infec- tion rate of Escherichia coli , KlebsieUa pneumoniae , Streptococcus pneumoniae , Haemophilus influenzae , Staphylococ- cus aureus and Enterobacter cloacae was 32. 3% ,20. 2% ,14. 8% ,13.2% ,13% ,7. 2% respectively. The infection rate and the percentage of infection pathogen were different between each age group because of the ages. Conclusion Be-fore the results of the sputum culture and drug sensitivity come out, the sensitive antibiotics treatment could be closen based on the age.
