简介:摘要目的探讨儿童慢性咳嗽的病因分布,发病年龄和临床特点。方法对2007年至2011年在本院病房住院诊治的29例慢性咳嗽患儿的临床资料进行总结和分析。结果29例中明确诊断28例,确诊率96.6%,确诊疾病中,反复呼吸道感染18例,咳嗽变异性哮喘2例,鼻后滴流综合征8例,支原体(MP)感染3例。确诊病例中单一病因25例,双重病因3例,,分别是咳嗽变异性哮喘合并鼻后滴流综合征2例,咳嗽变异性哮喘合并支原体(MP)感染1例。儿童慢性咳嗽最常见病因为反复呼吸道感染,其次为咳嗽变异性哮喘,鼻后滴流综合征。另外过敏性咳嗽,支原体(MP)感染,胃食道返流性咳嗽,肺结核也可导致慢性咳嗽。结论诊治慢性咳嗽患儿首先要根据不同年龄特点和不同病史特点行相关相应检查,查明病因,然后针对病因进行综合治疗。
