AbstractPostoperative atrial fibrillation following cardiothoracic surgery is common and frequently managed with intravenous (IV) amiodarone. Phlebitis is the most common complication with peripheral infusion of this agent. Current practice guidelines for peripheral IV administration of <2 mg/mL amiodarone were established to reduce the risk of phlebitis. The present study examines the incidence of phlebitis in a postoperative patient population given current dose recommendations. A total of 273 patient charts were reviewed. The incidence of phlebitis in patients given IV amiodarone (n = 36) was 13.9% (95% confidence interval, 2.6-25.2%; p = 0.001). Logistic regression analysis with backward elimination of other therapeutic risk factors suggests that the odds ratio for phlebitis using current dose regimens without IV filters is 19-fold greater than baseline risk in this population. Phlebitis remains a significant complication associated with peripheral infusion of amiodarone within recommended dosing limits.
