Objective To study the curative effect and pulmonary function impact of budesonide combined terbutaline aerosol inhalation for children with bronchial asthma. Methods 48 children with bronchial asthma admitted in pediatrics department of our hospital were selected as study objects, which were divided into observation group and control group according to the distribution method (24 cases in each group). Children in control group were treated by conventional methods, and children in observation group treated by budesonide combined terbutaline aerosol inhalation, the clinical effect and the changes of lung function were observed and compared. Results The clinical total effective rate of observation group (95.83%) was higher than that of control group (70.83%). After treatment, the blood gas indexes were better in both groups, moreover, the blood gas indexes of observation group was better than that of control group, the difference was statistically significant (P<0.05). Conclusion Budesonide and terbutaline aerosol inhalation has certain effect for children with bronchial asthma, which can improve their life quality. Thus, it’s worthy of clinic application.
