ABSTRACT
Objective:To observe the clinical efficacy and safety of modified Erchentang (Juhong Tanke liquid) on children bronchitis with syndrome of sputum, cough, dys-expectoration, wheezing and pulmonary function. Method:A total of 200 children patients aged below 24 months were randomly divided into control group and observation group by random number table, with 100 cases in each group. Children in each group received basic clinical treatment, while children in treatment group was also given modified Erchentang (Juhong Tanke liquid), 2-5 mL each time, 3 times a day. Both groups were treated for 15 days. Clinical respiratory tract symptom and sign scores, cough, sputum, dys-expectoration and wheezing were evaluated and compared. Pulmonary function was detected before and after treatment for 15 days. Analysis parameters were respiratory rate (RR), tidal volume per kilogram (VT/kg), inspiratory/expiratory (TI/TE), peak time of expiratory flow (TPTEF), time to peak ratio (TPTEF/TE), peak expiratory flow (PEF), volume in peak time of expiratory flow (VPTEF), volume ratio in peak flow (PFV), terminal flows per peak expiratory flow (25/PF), rate of mid-expiratory to mid-inspiratory flow (ME/MI), respiratory resistance (Rrs), functional residual capacity per kilogram (FRC/kg) and compliance per kilogram (Crs/kg). Result:After treatment for 5 days, both groups have obviously alleviation in sputum, cough, dys-expectoration wheezing and airway function. After treatment for 5 days, sputum, cough, dys-expiratory and wheezing in treatment group were all alleviated comparing with those of control group (PConclusion:Modified Erchentang (Juhong Tanke liquid) has shown marked efficacy in children bronchitis to alleviate clinical symptoms and improve pulmonary function, with no adverse reaction, and thus is worth further promotion and application in clinic.
