Neonatal hyponatremia

[Raeanne Dimick]

Hyponatremia is a serum sodium concentration lt; 135 mEq/L (gt; 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 in adults is discussed elsewhere.)
