Overview
Medical Therapy
To avoid myelinolysis, the correction of hyponatremia should not exceed 1 mEq/L per hour. [1][2] There is no specific treatment and the syndrome is associated with high mortality and morbidity. This being a potentially avoidable disaster, following recommendations may be adhered to while maintaining sodium levels:
Hyponatremia
The rate of correction of hyponatremia should be 0.5-1.0meq/L/hr, with not more than a 12 meq/l correction in 24 hrs. If the patient has ongoing seizures (or [Na+]<115 meq/li), correction can be attempted at up to 2 meq/L/hr, but only while seizure activity lasts and the [Na+] exceeds 125-130 meq/Li.
Hypernatremia
The rate of correction of hypernatremia should be at 0.5meq/L/hr and should not exceed 12 meq/Li/24hrs.
