Abstract 【Objective】 To explore the effect of Shufeng Liyan Decoction in the treatment of intractable laryngeal cough and its effect on airway resistance. 【Methods】A total of 102 patients with intractable laryngeal cough diagnosed and treated in the Department of Otorhinolaryngology of the Shaanxi Traditional Chinese Medicine Hospital from January 2017 to June 2020 were randomly divided into observation group and control group, with 51 cases in each group. The patients in the control group were treated with conventional western medicine, and the patients in the observation group were treated with Shufeng Liyan Decoction on the basis of the control group. The clinical efficacy, TCM syndrome score, immunoglobulin A (IGA), immunoglobulin G (IgG), immunoglobulin M (IgM), proximal pharyngeal viscous resistance (R35), central airway viscous resistance (R20), and total respiratory tract impedance (Zrs) levels were compared between the two groups before and after treatment. 【Results】The total effective rate of the observation group was 92.16%, significantly higher than 72.55% of the control group (P<0.05); The TCM syndrome scores of the two groups after treatment were significantly lower than those before treatment, and the observation group was significantly lower than that of the control group (P<0.05); IgA, IgG and IgM in the two groups after treatment were significantly higher than those before treatment, and those in the observation group were significantly higher than those in the control group (P<0.05); R35, R20 and Zrs in the two groups after treatment were significantly lower than those before treatment, and those in the observation group were significantly lower than those in the control group (P<0.05). 【Conclusion】 The Shufeng Liyan decoction is effective in the treatment of intractable laryngeal cough. It can improve the clinical symptoms, immune function and airway resistance of patients, which is worthy of clinical application.
