This study investigated the effects of perioperative inhaled tiotropium on patients with COPD undergoing esophagectomy, focusing on pneumonia risk and pulmonary function.
32 patients were randomly assigned to either a control group with conventional management or an intervention group receiving tiotropium inhalation before and after their surgery.
While the incidence of pneumonia was similar in both groups, the patients using tiotropium showed improved pulmonary function and exercise capacity, leading to less deterioration post-surgery.
