Abstract：Objective：To observe the clinical effect of Chinese medicine external therapy combined with pulmonary rehabilitation training on chronic obstructive pulmonary disease (COPD) in stable stage. Methods：A total of 106 COPD patients in stable stage were randomly divided into the control group and the study group， with 53 patients in each group. The control group was treated with routine pulmonary rehabilitation training， and the study group was additionally treated with Chinese medicine fumigation， auricular point bean- embedding， point application and other external treatment methods based on the treatment of the control group. Both groups were treated for 15 days. The traditional Chinese medicine (TCM) syndrome scores， blood gas analysis indexes， including arterial partial oxygen pressure (PaO 2 )， partial pressure of carbon dioxide (PaCO 2 ) and blood oxygen saturation (SaO 2 )，dyspnea grade and exercise endurance in the two groups were compared before and after treatment. Results：After treatment，the TCM syndrome scores of cough， sputum， panting and shortness of breath in the two groups were decreased when compared with those before treatment (P＜0.05)，and the above scores in the study group were lower than those in the control group (P＜0.05). After treatment，the PaO 2 and SaO 2 levels in the study group were increased when compared with those before treatment and with those in the control group (P＜0.05)， and the PaCO 2 level was respectively decreased when compared with that before treatment and that in the control group (P＜0.05). There was no significant difference in the comparison of the levels of PaO 2 ， PaCO 2 and SaO 2 before and after treatment in the control group (P＞0.05). After treatment，the dyspnea grade in both groups was improved when compared with that before treatment (P＜0.05)，and the dyspnea grade in the study group was better than that in the control group (P＜0.05). After treatment，the exercise endurance in the two groups was improved when compared with that before treatment (P＜0.05)，and the improvement of exercise endurance in the study group was better than that in the control group (P＜0.05). Conclusion：The Chinese medicine external therapy combined with pulmonary rehabilitation training can improve clinical symptoms，pulmonary ventilation function and oxygenation of COPD patients in stable stage.
