Critical care management of patients with barium poisoning

Potassium infusion is used clinically to reverse the toxic effects of barium. The highest rate of KCl supplementation in the representative case was 20.0 mmol/h, with a total dose of about 160 mmol (11.2 g) in 8 h. It was remarkable that barium-poisoned people tolerate potassium supplementation and recover quickly upon potassium restoration.

Barium Sulfate

Barium sulfate is a soft crystalline solid. It is a rhombic crystal. The pure salt is white but the color of the mineral "barite" can vary between red, yellow, gray or green, depending on impurities. Its density is 4.50 g/cm 3 and its refractive index is 1.64. It melts around 1580 °C but decomposes above 1600 °C.
