Abstract:Objective To observe the efficacy of bi-level positive airway pressure ventilator (BiPAP) and oxygendriven aerosol inhalation of budesonide in patients with acute exacerbation of chronic obstructive pulmonary diseases (AECOPD) and type 2 diabetes mellitus (T2DM). Methods A total of 110 AECOPD patients with T2DM were randomly treated with BiPAP (control group) or BiPAP plus oxygen-driven budesonide nebulization (observation group) for 7 days. Clinical efficacy, adverse reactions, blood gas, vital signs, inflammatory response, stress response, glucose metabolism, and pulmonary function indexes were compared between two groups. Results Compared with control group, PaCO2, heart rate, respiration, hs-CRP, WBC, MDA, DI were significantly decreased, while PaO2, SOD, FEV1% and FEV1/FVC increased in observation group (P < 0.01 or 0.05). The curative effect was better in observation group than in control group (P < 0.05). Conclusion BiPAP combined with oxygen-driven budesonide nebulization can improve the curative effect as well as blood gas, vital signs, inflammatory response, stress response and pulmonary function in patients with AECOPD and T2DM.
