Randomized Controlled Trial Clinical TrialMagnesium in addition to sotalol does not influence the incidence of postoperative atrial tachyarrhythmias after coronary artery bypass surgery.
Postoperative atrial tachyarrhythmias (POATs) after coronary artery bypass grafting (CABG) are reported in 11% to 40% of patients. Several etiologic factors are mentioned. Prophylactic intervention with sotalol is reported to reduce the incidence of POAT. The authors studied the effect of magnesium chloride (MgCl2) in addition to sotalol in the prevention of POAT. ⋯ These results show that MgCl(2), in addition to sotalol, is not more effective than sotalol alone in the prevention of tachyarrhythmias after CABG. The data showed that this combination may also induce serious bradyarrhythmias.
