肺炎支原体引起小儿上呼吸道感染的临床研究

目的探讨肺炎支原体引起小儿上呼吸道感染的临床特点,以提高其诊断水平。方法选择该院2009年5月-2011年5月收治的上呼吸道感染患儿100例(观察组),采用肺炎支原体培养,就其临床资料与健康小儿100例(对照组)进行比较分析。结果观察组阳性率为32.0%高于对照组的28.0%,差异有统计学意义(P<0.05)。观察组MP阳性患儿中,其中<1岁婴儿阳性率为18.8%显著低于其他年龄段,并显著高于对照组的10.7%,差异均有统计学意义(P<0.05);2组其他年龄段MP阳性率比较差异均无统计学意义(P>0.05)。32例阳性患儿均以发热、刺激性咳嗽为临床表现;胃肠道症状、卡他症状较为少见,均以扁桃体红肿、咽部充血为体征。无鼻窦炎、中耳炎、颈淋巴结炎、皮疹、眼结膜充血、口腔溃疡、疱疹。结论上呼吸道感染患儿临床无法确诊支原体感染或病毒感染时,可做肺炎支原体培养,操作方便,具有一定安全性和有效性,显著提高了诊断质量。

Clinical research of mycoplasma pneumoniae caused by upper respiratory tract infection in pediatric

Objective To investigate the clinical feature of mycoplasma pneumoniae caused by upper respiratory tract infection in pediatric. Methods Chose 100 cases children with upper respiratory tract infection in May 2009 to May 2011 （ observation group）, with myeoplasma pneomoniae culture, compared the clinical data of 100 cases healthy children （control group） and observation group. Results The positive rate of observation group （32.0%） was higher than that of control group （ 28.0% ）, the difference was statistically significant（ P 〈 0.05 ）. In MP positive patients of observation group, 〈 1 year old baby-positive rate （18.8%） was significantly lower than that of other age groups, and was significantly higher than that of control group（ 10.7% ） ,the difference were statistically significant（ P 〈 0.05 ） ;Other ages MP-positive rate of two groups were no sig- nificant difference （P 〉 0. 05 ）. 32 cases positive patients were fever, irritating cough for the clinical manifestations;Gastrointestinal symptoms, catarrhal symptoms were relatively rare, red and swollen were the tonsils,throat congestion for the signs. No sinusitis, otitis media, cervical lymphadenitis, rash, conjunetival hyperemia, oral ulcers, herpes. Conclusion Children with upper respiratory tract infection, the clinical can not be confirmed myeoplasma infection or viral infection, do mycoplasma pneumoniae culture, easy to operate with a certain safety and efficacy, significantly improves the diagnostic quality.
