Objective： To observe the clinical effect of Qingre Pingchuan tang combined with western medicine for patients with bronchial asthma in acute attack stage with heat-wheezing syndrome.MethodsDivided 84 cases of patients with bronchial asthma in acute attack stage with heat-wheezing syndrome into the control group and the observation group according to random number table method，42 cases in each group.Both groups receivedroutine western medicine，while the observation group additionally received Qingre Pingchuan tang，and the treatment of both groups lasted for 2 weeks.Observed and compared the clinical effect，onset time，lung function and adverse reactions in two groups.Results：The total effective rate was 95.24%in the observation group and was 73.81%in the control group，the difference being significant(P＜0.01).The onset time of controlling cough，expectoration，wheezing and wheezing rale in the observation group was all shorter than that in the control group，difference being significant(P＜0.01).The forced expiratory volume in one second(FEV1)in both groups was increased when compared with that before treatment(P＜0.01).FEV1value in the observation group was higher than that in the control group，the difference being significant(P＜0.05).The liver and kidney function of both groups was normal before and after treatment，and only 1 case of patient in the control group had hoarseness.ConclusionThe therapy of additional Qingre Pingchuan tang based on routine western medicine for bronchial asthma in acute attack stage with heat-wheezing syndrome can effectively improve the lung function of patients and control the main symptoms quickly and effectively with good drug safety.
