A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether prophylactic magnesium reduces the incidence of atrial fibrillation post cardiac surgery. Altogether 113 papers were found using the reported search, of which 21 represented the best evidence on this topic. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses were tabulated. We conclude that prophylactic magnesium reduces the incidence of arrhythmias post cardiac surgery with a number needed to treat of only 13 to prevent an episode of supraventricular arrhythmia.
根据结构化方案撰写了一篇心脏外科的最佳证据主题文章。探讨的问题是预防性使用镁是否能降低心脏手术后房颤的发生率。通过报告的检索共找到113篇论文，其中21篇代表了该主题的最佳证据。将作者、期刊、出版日期和国家、研究的患者组、研究类型、相关结局、结果及研究不足制成表格。我们得出结论，预防性使用镁可降低心脏手术后心律失常的发生率，预防一次室上性心律失常发作的所需治疗人数仅为13人。
