目的分析小儿肺炎支原体(MP)感染的临床特点,提高对小儿MP感染的临床认识,以进一步提高MP感染诊治水平。方法对2008年1月至12月本院收治的2193例住院患儿常规进行MP检测,并对MP感染住院患儿的临床资料进行总结分析,统计相关因素。结果MP阳性为351例,阳性率为16.01%。小儿下呼吸道感染1365例,MP阳性327例,阳性率为23.96%;136例婴幼儿中有78例(57.35%)肺部可闻及湿罗音,215例3岁以上患儿中有52例(24.19%),2者之间差异有统计学意义(P<0.01);136例婴幼儿出现肺外并发症者17例(12.50%),215例3岁以上患儿中出现62例(28.84%),2者间差异有统计学意义(P<0.01)。结论住院患儿MP感染临床表现在婴幼儿与3岁以上患儿间差异较大,前者肺部体征明显,后者则不明显,但后者肺外并发症发生率高。红霉素或阿奇霉素治疗效果较好。
Objective To analyze the clinical features of children with Mycoplasma pneumoniae (MP) infection and to improve the clinical knowledge of MP infection in children so as to further improve the diagnosis and treatment of MP infection. Methods 2193 hospitalized children admitted to our hospital from January 2008 to December 2008 were routinely tested for MP. The clinical data of hospitalized children with MP infection were analyzed and statistically analyzed. Results The positive rate of MP was 351 cases, the positive rate was 16.01%. 1365 cases of pediatric lower respiratory tract infection, MP positive 327 cases, the positive rate was 23.96%; 136 infants in 78 cases (57.35%) lungs can be heard and wet rales, 215 cases of children over 3 years of age 52 (24.19%). The difference between the two groups was statistically significant (P <0.01). Thirteen of 136 infants and young children had extrapulmonary complications (12.50% %), The difference between the two was statistically significant (P <0.01). Conclusion The clinical manifestations of MP infection in hospitalized children are quite different between infants and children over 3 years old. The former have obvious pulmonary signs but the latter are not obvious. However, the incidence of extrapulmonary complication in the latter is high. Erythromycin or azithromycin treatment is better.
