Clinical Trial Controlled Clinical TrialArrhythmia prophylaxis after coronary artery bypass grafting: regimens of magnesium sulfate administration.
Arrhythmias are common after open heart surgery and may be related to hypomagnesaemia due to cardiopulmonary bypass. Although perioperative prophylactic Mg2+ administration may prevent arrhythmias after coronary artery bypass grafting (CABG), clear indications as well as the timing of Mg2+ substitution and dose regimen need to be clarified. Aim of this study was to evaluate the antiarrhythmic effects of Mg2+ infusion in patients who underwent elective CABG. ⋯ Our results demonstrate that Mg2+ sulfate administration regimens used in Group B and C reduce postoperative arrhythmic events in patients undergoing CABG.
