门诊慢性咳嗽病因及治疗分析

目的：探讨慢性咳嗽的主要病因及其诊断标准，分析针对病因治疗的效果。方法：采用《咳嗽的诊断与治疗指南》诊断程序，对226例慢性咳嗽的病因进行诊断并通过分析治疗效果而确认。结果：226例慢性咳嗽中确诊216例（95．6％），其中咳嗽变异型哮喘（CVA）73例，鼻后滴流综合征（PNDs）52例，胃食管反流性咳嗽（GERC）40例，感染后咳嗽（PIC）31例，血管紧张素转换酶抑制剂（ACEI）诱发的咳嗽17例，嗜酸粒细胞性支气管炎（EB）3例；病因未明10例（4．4％）。确诊的216例针对性治疗后，201例咳嗽得到控制（93．1％），15例显效（6．9％）。结论：CVA、PNDs、GERC、PIC、ACEI诱发的咳嗽是慢性咳嗽的主要病因，针对病因的特异性治疗效果良好，并可作为确诊的重要依据。

The analysis of the pathogeny and treatment of chronic cough for outpatients

Objective：To investigate the main cause and the diagnostic criteria of chronic cough and analyse the effect of etiological treatment. Methods：Two hundred and twenty-six patients with chronic cough were diagnosed according to the Guideline for diagnosis and therapy of cough, and were confirmed by therapeutic effect. Results：Among 226 cases, 216 cases were confirmed, including 73 CVA, 52 PNDs, 40 GERC, 31 PIC, 17 drug-induced cough by ACEI , 3 EB and 10 etiologically unknown cases （4.4%）. After proper treatment, 93.1%（201/216） patients were cured, and the symptoms of 6.9% （15/216） patients were alleviated. Conclusion ：The main induced-chronic-cough causes are CVA, PNDs, GERC, PIC and ACEI drugs, and special treatment effectiveness targeting etiology can be regarded as an important basis for diagnosis of chronic cough.
