The goals of therapy with hypertonic saline can be summarized as 1) first, to remove patients with severe manifestations from immediate danger, 2) to correct the patient to a mildly hy-ponatremic level and 3) maintain this level of serum sodium allowing time for the brain to adjust to the change in serum osmolality.
Pseudohyponatremia may be circumvented by measuring sodium with a direct ion-selective electrode or by measuring serum osmolality (low in hyponatremia and normal in pseudohyponatremia).
With hydration, serum osmolality decrases which results in an osmotic gradient leads to water move from the intravascular to the intracellular space, decreasing intravascular volume.
