Hypernatremia

Hypernatremia

  • Same sign and symptoms of TBW depletion
  • Causes: dehydration, decreased water intake, osmotic diuresis, diabetes insipidus
  • Replace the deficit over 48-72 hours with solution hypotonic to patient’s serum
    • Don’t try to correct too quickly or it can lead to cerebral edema/death
    • Replace half of the calculated deficit with hypotonic solutions over 12-24 hours
