摘要： 目的探讨慢性孤立性咳嗽的病因诊断及其程序。 方法从首都医科大学附属北京儿童医院2003年10月至2004年8月在门诊就诊的58例慢性咳嗽患儿中，首先筛选慢性孤立性咳嗽病例，进一步根据咳嗽特征、辅助检查、治疗反应等确定慢性孤立性咳嗽的病因。 结果在58例慢性咳嗽的患儿中，筛选出慢性孤立性咳嗽50例，其中鼻后滴流综合征20例(8例慢性副鼻窦炎，6例慢性过敏性鼻炎，6例感染后鼻炎)、咳嗽变异性哮喘17例、感染后咳嗽5例、心理性咳嗽4例、原发性胃食道反流1例、嗜酸粒细胞性支气管炎2例、未明原因1例。 结论儿童慢性孤立性咳嗽的病因有鼻后滴流综合征、咳嗽变异性哮喘、感染后咳嗽、心理性咳嗽等。根据咳嗽特征、辅助检查、治疗反应等能确定绝大多数慢性孤立性咳嗽的病因。
