Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is an unignorable event in the management of chronic obstructive pulmonary disease. It is crucial to seek for effective management strategy. Compound sodium chlolate and aminophylline tablets are one of the most widely used drugs for the treatment of bronchial asthma and chronic bronchitis. Compared with the local bronchodilator recommended by the guidelines, it has the advantages of convenient use and good patient compliance. For the purpose of optimize the management of acute exacerbation of chronic obstructive pulmonary disease and provide more convenient options, we compared the efficacy of combined compound sodium chlolate and aminophylline tablets with nebulized ipratropium bromide inhalation plus systemic glucocorticoids in the treatment of chronic obstructive pulmonary disease ranging from moderate degree to severe degree. We hope this research would benefit patients with chronic obstructive pulmonary, especially those in the grassroots.
