Serum Magnesium Levels in Aortic and Mitral Valve Replacement Surgeries

Abstract

BACKGROUND:The purpose of the study was to analyze serum magnesium concentration in patients undergoing Aortic and Mitral Valve replacement surgeries. METHODS: This prospective study was conducted in 60 patients who underwent elective Aortic and Mitral valve replacement surgeries. Blood samples from radial artery were collected just before induction of anesthesia and three days post-operatively for estimation of serum magnesium. RESULTS: Magnesium level was 2.02mg/dl at baseline, 2.28mg/dl, 2.08mg/dl and 1.90mg/dl respectively on three consecutive days post-operatively. CONCLUSION: The lowering of serum magnesium in Aortic and Mitral valve replacement surgeries postoperatively recommends the use of routine serum magnesium determination and administration to prevent post-operative arrhythmias.
