摘要 目的探讨呈肺实变改变的肺部感染患儿的临床特点。方法将有呼吸道症状、体征和胸部CT呈肺实变改变的患儿按年龄分为3组:≤1岁组、1~3岁组、〉3岁组。分别对其临床表现、实验室及胸部CT结果、治疗与转归进行回顾性分析。结果≤1岁组细菌是主要致病原,以肺炎克雷伯菌占主要地位;全部为节段性肺炎,且往往累及多个段,以左右肺下叶背段及右上叶尖后段多见;患儿病情重,87.93%合并有基础疾病,先天性心脏病最多见,呼吸困难明显、肺部湿罗音多,预后差。〉3岁组患儿主要为肺炎支原体感染,以大叶性肺炎多见,右侧病变居多,病情相对轻,预后好。1~3岁组细菌和肺炎支原体感染混合存在,病情和预后介于前两组之间。总病程平均29 d,多数患儿预后良好,影像学恢复时间平均4周。结论肺实变改变的肺部感染患儿在不同年龄组肺实变的类型、病原体和临床表现有所不同,因此加强本地区一定时期内小儿肺部感染病原学的监测十分必要。
