Objective To observe the curative effect of pulmicort aerosol combined with terbutaline aerosol in the treatment of infants with mycoplasma pneumonia (MP).Methods 240 children with MP were selected and according to the different treatment method,they were divided into the observation group and control group.120 cases in the observation group were treated with pulmicort combined with terbutaline inhalation therapy.120 cases in the control group received budesonide inhalation therapy.Immunological parameters of IgG,IgE and TNF-α level,the main clinical symptoms and clinical efficacy were compared between the two groups.Results Compared with before treatment,IgG significantly increased,IgE and TNF-α level significantly decreased after treatment in the two groups,the differences were statistically significant (t =19.965,10.780,3.468,6.002,5.440,4.885,all P ＜ 0.05).And those in the observation group were better than the control group (t =13.920,4.523,2.729,all P ＜ 0.05).The remis sion time of clinical symptoms such as body temperature,wheezing,cyanosis,cough and pulmonary rales in the observation group were significantly shorter than those of the control group (t =2.991,6.034,4.623,8.562,7.113,all P ＜ 0.05).The obvious effective rate of the observation group was 93.3％,which was higher than 79.2％ of the control group (x2 =8.140,P ＜ 0.05).There were no significant adverse reactions in two groups.Conclusion Budesonide combined with terbutaline atomization inhalation in the treatment of infants with mycoplasma pneumonia has short remission time of clinical symptoms,good efficacy and less adverse reactions,it is worthy of promotion.
