Objective To discuss clinical effect of bronchodilator treatment on patients with chronic obstruc-tive pulmonary disease.Methods According to the exclusion criteria,106 patients were selected and randomly divid-ed into two groups,the control group were given glucocorticoid therapy,the study group was given glucocorticoid +bronchodilator treatment;lung index,including forced expiratory volume in one second,forced vital capacity,and the percentage of forced expiratory volume in one second of forced vital capacity of the two groups were compared,and the patientˊs clinical curative effect was observed.Results The patients of the study group of three indicators:forced expiratory volume in one second,forced vital capacity,forced expiratory volume in one second of forced vital capacity percentage were (1.6 ±0.8)L,(3.4 ±0.4)L,(48.6 ±2.3)%,which were higher than those of the control group, the differences were statistically significant (P <0.05);The total effective rate of the study group was 96.3%,which was higher than 81.2% of the control group,the difference was statistically significant (P <0.05).Conclusion The clinical effect of glucocorticoid +bronchodilator on patients with chronic obstructive pulmonary disease is good,which can effectively improve patient forced expiratory volume in one second,forced vital capacity,forced expiratory volume in one second percentage of forced vital capacity,and can avoid illness development,significantly improve the treat-ment efficiency.
