Methods A total of 109 infants with bronchiolitis in our hospital were randomly divided into treatment group and control group. The treatment group was treated by using epinephrine to dissolve in 3% hypertonic saline as inhalation therapy,and the control group by using salbutamol sulphate aerosol to dissolve in 0.9% saline as inhalation therapy. The symptom improvement,duration of hospitalization and changes in pulmonary function in the two groups before and after treatment were compared. Results After treatment,clinical symptoms and signs improved in the two groups,improvement in the treatment group being more significant,with shorter average hospital stay and better improvement in the average lung functions compared with the control group.
