Abstract
Objective: To explore the feasibility of tiotropium bromide therapy and its effect on the lung function of patients with asthma-COPD overlap syndrome (ACOS). Method: The 58 subjects selected in this study were all ACOS patients admitted to our hospital (Hohhot First Hospital) from October 2020 to October 2022. They were grouped according to the random number table method and divided into a control group (29 cases) and an observation group (29 cases). The control group received routine treatment plus salmeterol-fluticasone powder inhalation treatment, and the observation group received tiotropium bromide treatment. The relevant indicators of the two groups were compared. Results: The total clinical effective rate of the observation group was significantly higher than that of the control group. Besides, the forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) levels, and ACT scores of the two groups increased after treatment, with the observation group having better results than the control group. The residual volume-total lung capacity ratio (RV/TLC), acute exacerbation frequency, and CAT scores all decreased, with the observation group showing smaller values than the control group. The difference between the results of both groups were significant (P < 0.05) Conclusion: Tiotropium bromide has a significant clinical effect in the treatment of ACOS patients and can effectively improve the lung function of patients.
