Abstract
Background: We studied the incidence of magnesium (Mg) disturbances in patients admitted to a multidisciplinary intensive care unit (ICU) and correlated serum magnesium levels with clinical outcomes. Materials and methods: The study was conducted on 280 critically ill patients aged above 18 years and admitted to the ICU. Serum magnesium levels at admission were correlated with mortality, need for and duration of mechanical ventilation, duration of ICU stay, presence of comorbid conditions, and electrolyte disturbances. Result: = 0.001 and 0.005 respectively) were associated with hypermagnesemia. Conclusion: Our study highlights the role of Mg monitoring in critically ill patients admitted to the ICU and its value for a favorable outcome. We found that hypomagnesemia was significantly associated with adverse outcomes and higher mortality in critically ill patients. Intensivists should maintain a high index of suspicion for Mg disturbances and evaluate patients appropriately. How to cite this article: Gonuguntla V, Talwar V, Krishna B, Srinivasan G.
