Abstract:Objective To explore and analyze the effect of self-made Qingfeikuanxiongliqi decoction on patients with acute exacerbation of chronic obstructive pulmonary disease. Methods A total of 91 patients with acute exacerbation of chronic obstructive pulmonary disease admitted from April 2015 to May 2018 were randomly divided into western medicine group (45 cases) and combination group (46 cases). Western medicine group was treated by western medicine, while the combination group was treated by western medicine combined with self-made Qingfeikuanxiongliqi decoction. The changes of TCM syndrome scores, lung function, blood gas analysis indexes, clinical efficacy and adverse reactions before and after treatment were compared. Results After treatment, while the scores of TCM syndromes and PaCO2 in the two groups decreased (P < 0.05), those in the combined group were lower than those in the western medicine group (P < 0.05). After treatment, FEV1, FVC, FEV1/FVC, PaO2 and pH value of the two groups increased (P < 0.05), and those of the combined group were higher than those of the western medicine group (P < 0.05). The total effective rate of the combined group was higher than that of the western medicine group (P < 0.05). There was no significant difference in the incidences of adverse reactions between the combined group and the western medicine group (P > 0.05). Conclusion On the basis of western medicine treatment, self-made Qingfeikuanxiongliqi decoction can significantly control symptoms, improve pulmonary function and blood gas analysis indexes, enhance the therapeutic effect of western medicine, and will not significantly increase adverse reactions.
