Intravenous (i.v.) calcium chloride is usually given to treat symptomatic hypocalcemia; however, the extravasation of calcium solution may cause soft tissue and skin necrosis. After parathyroidectomy and autotransplantation for secondary hyperparathyroidism associated with end-stage renal failure, i.v. calcium infusion is often necessary to treat severe postoperative hypocalcemia. We reviewed 371 patients who underwent parathyroidectomy for secondary hyperparathyroidism between January 2000 and June 2005, 96 of whom received i.v. calcium postoperatively for symptomatic hypocalcemia. ⋯ Moreover, the calcium solution infusion should be ceased if the patient complains of tenderness over the injection site. If skin necrosis develops, we suggest early debridement and a simple split thickness skin graft to repair the skin defect. We report our experience to remind surgeons of the danger of calcium chloride injection and to discuss ways of preventing and treating this complication.
