OBJECTIVE To assess the effect of preoperative dexamethasone on the occurrence of postoperative atrial fibrillation. METHODS Random controlled trails were gathered though searches of PubMed (1966 - 2009.11), EMBASE (1974 - 2009.11), Cochrane Library (issue 4, 2009), Chinese Biomedical Literature Database (1978 - 2009.11), China Journal Full-text Database (1994 - 2009.11), Chinese Scientific Journals Full-text Database (1989 - 2009.11). Two reviewers independently assessed eligibility and quality of trials, then extracted data. Data were synthesized using RevMan5.0 software provided by the Cochrane Collaboration. RESULTS A total of four randomized controlled trials (667 participants) were included for systematic review. Meta-analysis showed that there were statistical differences between dexamethasone and placebo in postoperative atrial fibrillation (RR = 0.6, 95%CI: 0.40 to 0.92, P = 0.02), dexamethasone did not reduce post-operative mortality (RR = 0.79, 95%CI: 0.28 to 2.22, P = 0.66). CONCLUSIONS The current evidence shows that dexamethasone could reduce the incidence of atrial fibrillation after cardiac surgery, not decrease mortality. There were few limitations in our study may lead to weaken reliability of the conclusions, such as small simple size, different operation types, or the dosage, time and frequency of dexamethasone were unclear. Its effectiveness was needed to further validate in future clinical studies.

D001281	Atrial Fibrillation	Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
