RESUMO
Objective To explore clinical effect of small dose of glucocorticoid in the treatment of AECOPD patients with severe disease associated with low levels of cortisol.Methods72 patients with AECOPD in our hospital were randomly divided into control group and treatment group.The control group was treated with conventional AECOPD method,the treatment group was treated on the base of the treatment group with a small dose of corticosteroids,CRP, IL-6, TNF-α, FEV1, PCT and other indicators, as well as patients with ventilation, shock and mortality were compared after the end of treatment.ResultsThe time of non mechanical ventilation, the time of non-mechanical ventilation, and the time of non-shock were increased, the shock and the mortality was lower in the treatment group,(P<0.05);The CRP level of patients in the treatment group was lower(P<0.05);IL-6, TNF-α, PCT levels of patients in the treatment group was lower (P<0.05);FEV1, FVC and FEV1/FVC level in the treatment group were higher(P<0.05).ConclusionSmall dose glucocorticoid can improve the pulmonary function of patients with AECOPD complicated by severe disease, and alleviate the disease, significantly reduce the levels of inflammatory factors, promote the improvement of the lung function.
