Hypokalemia due to barium carbonate intoxication / 대한내과학회지

ABSTRACT

Barium carbonate is commonly used rodenticidally and industrially, but intoxication has been uncommonly reported. Muscle weakness and hypokalemia are the characteristic features of barium carbonate intoxication. Barium-induced hypokalemia is due to a rapid and large transfer of potassium from the extracellular space into the intracellular space resulting from blocking potassium channels by barium ions. We report 35 cases of barium carbonate intoxication which developed after accidental ingestion of barium poisoned noodle. All patients developed severe hypokalemic paralysis and some degree of vomiting and diarrhea. We managed these patients with aggressive potassium supplementation and all patients were discharged without any sequelae.
