title: Acute peritoneal dialysis as both cause and treatment of hypernatremia in an infant.
abstract: This report describes a 4-month-old infant with multisystem organ failure who developed severe hypernatremia (sodium 168 mEq/l) due to rapid free water removal associated with acute peritoneal dialysis instituted for fluid overload. The current report describes the pathophysiology of the hypernatremia, and its correction by low-sodium hypertonic peritoneal dialysis without compromising ultrafiltration or supplementing with free water. Although peritoneal dialysis can cause hypernatremia, a modified solute concentration in the dialysate can treat the hypernatremia successfully.
