摘要：

One hundred and thirty patients undergoing elective myocardial revascularisation were randomised to receive an intravenous infusion containing either 50 mmol magnesium chloride or placebo during the first 48 h following surgery. Magnesium was given to 66 patients and a placebo infusion to 64 patients. Postoperative serum magnesium concentrations fell in the placebo group (from 0.83 +/- 0.06 to 0.79 +/- 0.11 mmol/1) but were elevated in the magnesium group (from 0.82 +/- 0.05 to 1.2 +/- 0.25 mmol/1). In total, 35 patients (26.9 %) had a supraventricular arrhythmia, of which 11 were in the magnesium group (16.7 %) and 24 (37.5 %) in the placebo group (P = 0.013). Three patients in the magnesium group had an episode of ventricular fibrillation and three patients in the placebo group had frequent ventricular ectopics. There was one death in the magnesium group associated with a perioperative myocardial infarction. This study shows that intravenous magnesium supplements reduce the incidence of supraventricular arrhythmias following coronary artery surgery.
