儿童社区获得性支原体肺炎病原学与影像学特征分析

目的:回顾性分析我院儿童社区获得性肺炎(Community-acquired pneumonia,CAP)患儿病原学检测结果,为本地区CAP患儿的临床治疗提供参考依据。方法:选取2014年5月-2018年5月812例符合中华医学会儿科学分会制定的儿童社区获得性肺炎(2013修订)诊断标准的CAP患儿,分析患儿的临床特征及影像学检查结果,并进行分析。结果:非重症CAP患儿812例,CAP占10.2%;感染病原体例数481例,阳性检出率为59.2%;1月-1岁龄组与1-5岁龄组比较差异无统计学意义(P0.05);5-14岁龄组发热发生率明显高于前两组,差异均有统计学意义(P0.05)。咳嗽、喘息、固定湿啰音发生率集中在1月-1岁龄组与1-5岁龄组,且高于5-14岁龄组发生率(P0.0);肺部影像学改变的患儿共657例,占80.9%。三个年龄组;肺部影像学改变差异有统计学意义(P0.05)。结论:不同年龄段CAP患儿病原体检出率不同;不同年龄和不同病原学感染的儿童CAP的影像学表现各有特点,对于临床医生早发现、早诊断、早治疗具有一点的指导性意义。

Community Acquired Mycoplasma Pneumonia in Children and Its Imaging Analysis

ABSTRACT Objective: The results of pathogen of children with Community-acquired pneumonia (CAP) in our hospital were analyzed retrospectively, so as to provide reference for the clinical treatment of children with CAP in the local area. Methods: 812 children with children''s community acquired pneumonia (2013 Revised) diagnosed as CAP were selected from May 2014 to May 2018. The clinical features and imaging findings of children were analyzed and analyzed. Results: There were 812 cases of non-severe CAP, CAP accounted for 10.2%; 481 cases of infectious pathogens, positive detection rate was 59.2%; there was no significant difference between 1-1 year-old group and 1-5 year-old group (P > 0.05); the incidence of fever in 5-14 year-old group was significantly higher than that in the first two groups (P < 0.05). The incidence of cough, wheezing and fixed moist rales was higher in 1-1 year-old group and 1-5 year-old group than that in 5-14 year-old group (P < 0.0); 657 cases (80.9%) had lung imaging changes. There were significant differences in pulmonary imaging between the three age groups (P<0.05). Conclusion: the pathogeny rate of CAP in children of different age groups is different, and the imaging manifestations of CAP in children with different age and pathogenic infection have their own characteristics. It has a guiding significance for the early detection, early diagnosis and early treatment of the clinicians.
