Abstract

Hyponatremic encephalopathy is a potentially lethal condition with numerous reports of death or permanent neurological injury. The optimal treatment for hyponatremic encephalopathy remains controversial. We have introduced a unified approach to the treatment of hyponatremic encephalopathy which uses 3% NaCl (513 mEq/L) bolus therapy. Any patient with suspected hyponatremic encephalopathy should receive a 2 cc/kg bolus of 3% NaCl with a maximum of 100 cc, which could be repeated 1–2 times if symptoms persist. The approach results in a controlled and immediate rise in serum sodium with little risk of inadvertent overcorrection.
