title: Systematic Review and Meta-analysis of Atrial Fibrillation Prophylaxis After Lung Surgery.
abstract: Atrial fibrillation (AF), which increases morbidity and mortality, is a common occurrence after thoracic surgery and pulmonary resection. Despite several investigations on various prophylactic measures for AF prevention, the studies were not uniform and do not use similar controls making it difficult to arrive at a meaningful conclusion. In the present systematic analysis review, we evaluated the efficacy of different prophylactic approaches to prevent AF after lung surgery in randomized trials reported during 1991-2014. A total of 12 trials were identified that met the criteria set for this meta-analysis. Among different trials, amiodarone was found to be most effective in preventing postoperative AF (risk ratio, 0.22; P < 0.0001; 95% confidence interval: 0.09-0.54). There were no significant prophylactic effects by MgSO4 (risk ratio, 1.24; P < 0.007; 95% confidence interval, 0.27-5.68), digoxin, or Ca blockers. Single use of amiodarone was able to lower the incidence of AF from 39.2% to 8.3% and seemed to be safe with no major complications. Although several prophylactic measures have been tried to curtail the incidence of AF in patients after lung surgery, prophylaxis with amiodarone seems to be most effective of treatments studied.
