Serum Magnesium Levels in Off - Pump Coronary Artery Bypass Grafting

Abstract

ABSTRACT:Magnesium plays an essential role in cardiac protection. Magnesium has many beneficial effects like it improves contractility and reduces the number of cardiac arrhythmia episodes. The aim of the study was to analyze the magnesium concentration in patients undergoing off-pump CABG. The study included 110 patients who underwent general anesthesia and coronary artery bypass graft. Magnesium level was 2.0mg/dl at baseline, 2.18 mg/dl, 2.02 mg/dl and 1.94 mg/dl respectively on 3 consecutive days post-operatively. The lowering of magnesium recommends routine serum magnesium determination to prevent complications.

“…In the present study we illustrated that there were no statistically significant differences between groups as regard surgical mortality. This is in agreement with the study of El Amrousy et al (6) in which there was no statistically significant difference between groups as regard postoperative surgical mortality.…”

“…Magnesium is an important regulator of multiple cardiovascular processes, including myocardial conduction and contractility, transmembrane calcium flux, potassium transport, vascular smooth muscle tone, coronary reactivity, and nitric oxide synthesis (5) . Inasmuch as magnesium is an essential cofactor for the maintenance of myocardial transmembrane potential, magnesium deficiency decreases the threshold for arrhythmias (6) .…”
