Effect of Ambroxol Hydrochloride Combined with Pulmonary Rehabilitation on Elderly Patients with COPD and Pulmonary Infection

Objective: To analyze the effect of ambroxol hydrochloride combined with pulmonary rehabilitation in elderly patients with chronic obstructive pulmonary disease (COPD) and pulmonary infection. Methods: A total of 80 elderly patients with COPD combined with pulmonary infection, admitted between January 2022 and December 2023, were randomly divided into an observation group and a control group. The observation group received ambroxol hydrochloride combined with pulmonary rehabilitation, while the control group was treated with ambroxol hydrochloride alone. The efficacy of the two treatments was evaluated. Results: The observation group exhibited a shorter clinical symptom resolution time (P < 0.05). Following treatment, the observation group demonstrated higher oxygen saturation levels and lower levels of inflammatory factors, including interleukin-6 (P < 0.05). Additionally, the lung function index in the observation group improved significantly (P < 0.05). Conclusion: For elderly patients with COPD and pulmonary infection, pulmonary rehabilitation training effectively enhances the resolution rate of clinical symptoms, reduces inflammatory factor levels, improves oxygen saturation, and facilitates pulmonary function recovery.
