慢性咳嗽患者60例病因分析

目的探讨慢性咳嗽的病因诊断及其分布.方法通过询问病史、体格检查、胸部X线、肺功能、食道pH监测等检查,明确病因,并对病因分类,针对病因进行特异性治疗.结果 60例慢性咳嗽病因分析发现,鼻后滴漏综合征为35%(21/60),胃食管反流为30%(2/60),变异型哮喘为26.7%(16/60),嗜酸细胞性支气管炎为3.3%(2/60),双病因为5%(3/60),病因未明者为5%(3/60).经针对病因特异性治疗后,94.7%(54/57)患者咳嗽明显减轻或消失.结论慢性咳嗽病因主要为鼻后滴漏综合征、胃食管反流、变异型哮喘、嗜酸细胞性支气管炎,占总病因的95%;询问病史及行试验性诊断治疗有效是确诊病因的重要环节.

The etiological analysis for 60 cases of chronic cough

Objective To investigate the etiological diagnosis and distribution of chronic cough.Methods The causes of chronic cough was observed by asking disease history,physical examination,X ray test,detecting lung function and pH in esophagus.Results Among the 60 patients,the causes included postnasal drip syndrome(21/60,35%),gastroesophaseal reflux(18/60,30%),cough variant asthma(16/60,26.7%),eosinophilic bronchitis(2/60,3.3%) and two causes(3/60,5%).There were 3 patients whose causes of disease were not found.After active(treatment) based on the diagnosis,cough was improved in 54 patients(94.7%).Conclusion The postnasal drip(syndrome,)gastroesophaseal reflux,cough variant asthma and eosinophiloc bronchitis are major causes of chronic cough.asking disease history and a positive response to the specific therapy is essential to a definite diagnosis.
