Abstract: AIM: To investigate the clinical values about budesonide of inhaled corticosteroids in the treatment of children with cough variant asthma.METHODS: The 94 cases of cough variant asthma children admitted to hospital from March 2007 to March 2011 were randomly divided into two groups, control group (n=47) and treatment group (n=47). The control group was treated with montelukast tablets and salbutamol aerosol, but the treatment group was also given budesonide dry powder inhaler. The clinical effects, the scores of asthma symptom, the time of cough symptom disappeared, and the level of lung function in 2 groups was observed and compared.RESULTS: The total effective rate in the treatment group was significantly higher than the control group (P<0.05); the symptom scores in the treatment group was significantly lower than the control group (P<0.05); the time of cough symptoms disappeared in the treatment group was significantly shorter than the control group (P<0.05); the index value of lung function in the treatment group were significantly better than the control group (P<0.05).CONCLUSION: There is a significant clinical efficacy about budesonide of inhaled corticosteroids for the treatment of children with cough variant asthma.
