Abstract

Magnesium is gaining recognition as a clinically important electrolyte. Hypomagnesemia has been associated with a variety of disorders including seizures, malignant ventricular dysrhythmias, and sudden death. The emergency department patients who are most likely to be magnesium deficient include alcoholics, patients who take diuretics, and those in diabetic ketoacidosis. Hypokalemia and hypocalcemia may represent unrecognized hypomagnesemia. Clinical trials and case reports also document increasing interest in magnesium as an effective therapeutic agent for potentially life-threatening problems such as torsade de pointes, digitalis toxicity, bronchospasm, and alcohol withdrawal. We present an overview of hypomagnesemia, review the current literature, and focus on the role of magnesium in the acute care setting and the implications for the emergency physician.
