Neonatal Hyponatremia
Introduction
Hyponatremia is a serum sodium concentration<135 mEq/L (<135 mmol/L). Significant hyponatremia may cause seizures or coma. Treatment is cautious sodium replacement with IV 0.9% saline solution; rarely, 3% saline solution is required, particularly if seizures are occurring. ( Hyponatremia is discussed elsewhere.)
