咳嗽变异性哮喘患者诊断中肺功能检查的应用价值评析

Evaluation of the Value of Pulmonary Function Tests in the Diagnosis of Cough Variant Asthma

目的分析肺功能检查在咳嗽变异性哮喘患者诊断中的价值。方法方便选取2016年3月—2017年3月在该院进行诊治的反复咳嗽60例,对所有患者进行肺通气功能以及气道反应性的测定。结果针对60例反复咳嗽的患者进行肺功能检测后,发现有48.33%(29/60)患者其肺功能存在异常;进行支气管舒张舒张试验的阳性患者有36.67%(22/60),男女患者的阳性率差异无统计学意义(χ2=0.06,P>0.05);反复性咳嗽病患在进行支气管舒张试验、临床诊治后,诊断有33.33%(20/60)患者为咳嗽变异型哮喘。结论对反复咳嗽患者予以肺通气功能以及气道反应性的测定,可确诊咳嗽变异性哮喘(CVA),有助于早期诊断反复咳嗽的病因。

Objective To analyze the value of lung function tests in the diagnosis of cough variant asthma. Methods A total of 60 patients with recurrent cough in the hospital from March 2016 to March 2017 were convenient selected. All patients were tested for pulmonary ventilation and airway responsiveness. Results After pulmonary function tests were performed on60 patients with repeated cough, 48.33%（29/60） patients were found to have abnormal lung function; 36.67%（22/60） of the positive patients had bronchodilator relaxation test. There was not statistically significant in the positive rate of patients（χ^2=0.06, P〉0.05）. After repeated bronchodilation tests and clinical diagnosis and treatment in patients with recurrent cough,33.33%（20/60） of patients were diagnosed as cough variant asthma. Conclusion The determination of pulmonary ventilation and airway responsiveness in patients with recurrent cough can be used to confirm the diagnosis of cough variant asthma（CVA）, which is helpful in the early diagnosis of recurrent cough.
