【摘要】 ①目的评价气道反性测定的临床应用价值。②方法测定哮喘缓解期、慢性咳嗽、胸闷病人及正常人的气道反应性，并随访支气管扩张剂治疗效果。③结果气道反应性测定诊断哮喘的敏感性为９０．５％，特异性为９３．３％；慢性咳嗽病人中气道高反应性（ＢＨＲ）者占７９．６％，胸闷病人中ＢＨＲ者占６２．７％，其中ＢＨＲ者接受支气管扩张剂治疗，总有效率达９２．４％。④结论气道反应性测定对哮喘，尤其是隐匿型哮喘具有重要诊断价值。更多还原

【Abstract】 Objective To evaluate the clinical application of the bronchial responsiveness test. Methids Bronchial re- sponsiveness was tested in patients with stable asthma, chronic cough, dyspnea and normal controls respectively by using asto- graph TCK-600CV. The post bronchodilator effect in patients with chronic cough and dyspnea was monitared by follow up study. Rerults The sensitivity of bronchial hyperresponsiveness (BHR) in diagnosing asthma was 90.5 %, specificity 93. 3%. BHR was found in 79. 6% patients with chronic cough, 62. 7% with dyspnea, and that the total effective rate was 92. 4% in those under bronchodilator therapy. Conclusion BHR is of important value in diagnosing asthma,especially in diagnosing occult asthma.更多还原
