Hypocalcemia, hypomagnesemia, and hypokalemia following hydrofluoric acid chemical injury.

Dermal exposure to hydrofluoric acid could potentially result in severe serum calcium and magnesium depletion induced by binding with fluoride anion. This report describes the case of a 48-year-old man who developed hypocalcemia and hypomagnesemia accompanied by hypokalemia-an interesting finding-following a chemical injury with exposure to 70% hydrofluoric acid. Successful treatment included administration of calcium gluconate and magnesium both intravenously and topically.
