title: Role of dialysis in the treatment of severe hypercalcemia: report of two cases successfully treated with hemodialysis and review of the literature.
abstract: The role of dialysis in the treatment of patients with severe hypercalcemia is uncertain. The fourteen previously reported cases of hypercalcemia treated with either peritoneal or hemodialysis have been reviewed. Two additional patients treated with hemodialysis are described in this report. Because the use of large volumes of intravenous fluids was contraindicated, each of the patients received a low calcium bath (0-1 mEq calcium per liter) hemodialysis for three and a half hours. After dialysis, the serum calcium fell to normal in both and remained normal thereafter with treatment of the underlying disease (multiple myeloma in one and vitamin D intoxication in the other). Hemodialysis can clear up to 682 mg of calcium per hour as compared to 124 mg per hour for peritoneal dialysis and 82 mg per hour with forced saline diuresis. Low calcium bath hemodialysis is indicated when the presence of renal and/or cardiac failure prevents the administration of large volumes of intravenous fluids to hypercalcemic patients.
