摘要
目的通过对90例支气管舒张试验阳性的哮喘患者的临床资料和支气管舒张试验结果进行总结分析,以了解影响支气管舒张试验结果的因素。方法对90例哮喘患者进行肺通气功能及支气管舒张试验,然后分析其检查结果。结果 1.哮喘患者病程、吸烟指数与支气管舒张试验中FEV1改善率有线性回归关系;2.基础肺功能、既往用药情况与FEV1改善率无线性回归关系;3.不同病程组哮喘患者支气管舒张试验FEV1改善率有明显不同,呈现为中病程组>短病程组>长病程组的变化趋势。结论支气管舒张试验是测定哮喘患者气道气流受限可逆性的可靠方法 ,但其结果受到患者的病程、吸烟指数、基础肺功能、用药等因素影响,其中以病程因素影响最为明显,表现为病程越长,FEV1改善率越低。
Objective To find out the influencing factors of bronchodilation test by analyzing the clinical data and lung function characteristics of 90 asthma patients.Methods Ninety patients with asthma were performed lung function examination and bronchodilation test,and then the test results were analyzed.Results There was a linear regression relationship between the course of the disease,smoking index of asthma patients and the improvement rate of FEV1.There was no linear regression relationship between the basal lung function,previous drug use of asthma patients and the improvement rate of FEV1.There were clear differences in the improvement rate of FEV1 in different courses of the disease.Conclusion The bronchodilation test is a reliable method to determine the airflow limitation reversibility of asthma patients,which is affected by the course of the disease,smoking index,basal lung function,previous drug use of asthma patients,and the course of the disease has the most obvious impact on bronchodilation test.
