Objective: To analyze the effect of combined inhalation of budesonide formoterol and tiotropium bromide
on arterial blood gas and pulmonary function indexes in patients with chronic obstructive pulmonary disease (COPD). Methods: 100 patients with COPD treated from January to December 2022 were selected as observation objects, and were divided into a control group (n = 50, in which budesonide and formoterol were administered) and an experimental group (n = 50, the treatment drug was budesonide formoterol combined with tiotropium bromide) according to the computer grouping method, and compared the treatment results. Results: (i) Before treatment, there was no difference in the partial pressure of carbon dioxide and partial pressure of oxygen between the control group and the experimental group (P > 0.05); after treatment, the partial pressure of carbon dioxide and partial pressure of oxygen in the experimental group were higher than those in the control group, with significant differences (P < 0.05). (ii) Before treatment, there was no difference in forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC between the control group and the experimental group (P > 0.05); after treatment, the FVC, FEV1, and FEV1 /FVC in the experimental group were
significantly higher than those in the control group (P < 0.05). (iii) There was no difference in the levels of CRP, IL-6, and TNF-α between the control group and the experimental group (P > 0.05); after treatment, the levels of CRP, IL-6, and TNF-α in the experimental group were lower than those in the control group, with significant differences (P <0.05). (iv) Compared to the total incidence of adverse reactions in the control group (28.00%), the incidence of total adverse reactions in the experimental group was lower at 10.00%, and the difference was significant (P < 0.05). Conclusion: The combined inhalation of budesonide and formoterol with tiotropium bromide has demonstrated a clear therapeutic efficacy and safety in treating chronic obstructive pulmonary disease. This treatment approach effectively enhances arterial blood gas levels and lung function, showing promising potential for widespread application.
