目的:探讨慢性咳嗽患者气道反应性检查的临床价值。方法:对2007-09/2008-09在本院就诊的103例慢性咳嗽患者,用支气管激发试验检查其气道反应性,进一步分析慢性咳嗽与气道高反应性之间的相关性。结果:43例患者支气管激发试验阳性,阳性率41.75%。结论:对于慢性、顽固性咳嗽患者,肺部体征及检查无阳性发现、而临床常规治疗效果差的患者,气道反应性检查是确诊或排除哮喘的有力依据。
Objective: To investigate the clinical value of airway reactivity test in patients with chronic cough. Methods: A total of 103 patients with chronic cough treated in our hospital from September 2007 to September 2008 were tested for bronchial airway responsiveness by bronchial provocation test. The correlation between chronic cough and airway hyperresponsiveness was further analyzed. Results: The bronchial provocation test was positive in 43 patients, the positive rate was 41.75%. CONCLUSIONS: In patients with chronic, refractory cough, no signs and tests of lung findings were found, whereas patients with poor clinical routine treatment and airway reactivity were strong predictors of asthma.
