What should be done if correction of dysnatremia is too rapid?
As the onset of symptoms of osmotic demyelination occurs days after over-rapid correction, preemptive administration of electrolyte-free water with or without desmopressin (synthetic vasopressin) to block further urinary electrolyte-free water loss is warranted to re-lower the serum sodium to the target increase level even in the absence of ODS symptoms.
