为探讨蒸馏水气道激发试验对 CVA的诊断价值及其安全性 ,应用蒸馏水激发试验对慢性干咳进行了检测。结果显示 ,CVA在慢性干咳人群中的发生率较高 ,对于基础肺功能无阻塞的慢性干咳者蒸馏水激发试验可作为诊断 CVA的一种安全的重要的诊断手段 ;MEF2 5基础值 =5 5可作为决定慢性干咳患者是否进一步行气道激发试验的粗筛界限。
To investigate the diagnostic value and safety of distilled water in airway provocation test for CVA, chronic dry cough was tested by distilled water challenge test. The results showed that the incidence of CVA in chronic dry cough is high, and the distilled water challenge test of chronic dry cough without obstruction of basic pulmonary function can be used as a safe and important diagnostic tool for diagnosing CVA. The basic value of MEF2 5 = 5 5 As a decision to determine whether chronic airway irritation tests in patients with chronic dry cough limits.
