Efficacy of intraperitoneal calcium for hungry bone syndrome following parathyroidectomy: A case report

A man with hyperparathyroidism secondary to kidney failure on peritoneal dialysis underwent a parathyroidectomy with half-gland reimplantation complicated by severe hungry bone syndrome resulting in severe hypocalcaemia, hypotension and QT prolongation on ECG. He was initially managed with oral calcium and intravenous (IV) calcium chloride. Despite standard supportive treatment, attempts to wean IV therapy were unsuccessful. We report the novel use of intraperitoneal calcium to facilitate the weaning of IV calcium and discharge from hospital. A subsequent peritoneal membrane adequacy study did not demonstrate loss of peritoneal membrane adequacy.
