目的:探讨过敏性鼻炎患者的肺功能变化及临床意义。方法:对38例无支气管哮喘症状的过敏性鼻炎患者进行肺通气功能及气道反应性测定。结果:肺通气功能异常18例(47.4%),其中阻塞性通气功能障碍2例,小气道功能异常16例。肺通气功能异常患者支气管激发试验阳性率高于肺通气功能正常患者(P<0.01)。结论:对无哮喘症状的过敏性鼻炎患者进行肺通气功能测定,并对异常者及时进行气道反应性测定,对过敏性鼻炎合并支气管哮喘的早期发现与治疗具有临床意义。
Objective: To investigate the changes of pulmonary function in patients with allergic rhinitis and its clinical significance. Methods: Thirty-eight patients with allergic rhinitis without bronchial asthma were evaluated for pulmonary ventilation and airway responsiveness. Results: There were 18 cases (47.4%) with abnormal lung ventilation, including 2 cases of obstructive ventilatory dysfunction and 16 cases of small airway dysfunction. The positive rate of bronchial provocation test in patients with abnormal pulmonary function was higher than that in patients with normal pulmonary function (P <0.01). Conclusion: It is of clinical significance to detect pulmonary ventilation in patients with allergic rhinitis without asthma symptoms and to evaluate the airway reactivity in time and to detect the early stage of allergic rhinitis with bronchial asthma.
