Hypocalcemic tetany due to sodium phosphate ingestion in acute renal failure

Abstract

The ingestion of a sodium phosphate laxative preparation (Phosphosoda, Fleed) in a patient who had acute renal failure resulted in hypocalcemic tetany primarily due to severe hyperphosphatemia. Hypernatremia and a marked anion gap were present and attributable in part to the sodium phosphate ingestion of this preparation in the presence of renal failure.
