Severe hypercalcemia following neonatal liver transplantation.

A 3-week-old infant with liver failure underwent an orthotopic liver transplant. Following a prolonged second surgical procedure in which he received massive amounts of blood products, his serum calcium was 31.3. mg/dl (7.8 mmol/l). This patient represents a case of severe hypercalcemia secondary to intraoperative calcium infusions given in an effort to overcome infusion-related citrate toxicity in a neonate with hepatic dysfunction.
