Objective. This study intended to systematically evaluate the effectiveness and safety of modified Dachengqi Decoction (MDD) combined with conventional treatment for treating acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Method. An extensive search was performed within 6 English and Chinese electronic databases from inception to April 2012. Methodological quality was assessed according to Cochrane risk of bias assessment. Data were analyzed using Review Manager 5.1. Results. A total of 16 studies (involving 1112 patients) were included. The result showed that MDD and its modification combined with routine treatment were more effective in improving FEV1%pred, enhancing the significant effectiveness, reducing PCO2, and shortening duration of mechanical ventilation. Adverse events were reported in two trials with symptom of diarrhea, while no serious adverse effect was reported. Conclusion. Modified Dachengqi Decoction appears to be effective for treating AECOPD. However, more regular designed RCTs are needed because of insufficient methodological problems.
