[Hypomagnesemia associated with hypokalemia, hyponatremia and metabolic alkalosis. Possible complication of gentamycin therapy].

Hypomagnesemia is a serious abnormality with different causes and usually associated to other disorders of electrolyte metabolism. We report a female patient developing hypomagnesemia after administration of gentamycin. This was associated to severe hypokalemia, hyponatremia and metabolic alkalosis. Possible pathogenetic mechanisms and therapeutic measures are discussed.
