Hypernatremic dehydration due to concentrated infant formula: report of two cases. Aim to replace deficit plus maintenance and ongoing losses. However in the acute resuscitation phase, it doesn't matter whether the patient is hyponatremic, normonatremic or hypernatremic, because the initial IV fluid indicated for resuscitation bolus infusions is NS or LR. Lethargy, weakness, irritability, coma, altered mental status, seizures, severe oliguria, thrombosis, brain hemorrhage, tachypnea, respiratory failure, and doughy skin texture are the signs of severe dehydration (≥ 15%). If hypernatremia is corrected too quickly in the setting of chronic hypernatremia, the lowering of the serum osmolality can lead to water movement into the brain cells causing brain edema. Estimate deficits of volume, sodium and potassium and write IV therapy orders for patients with hyponatremic or hypernatremic dehydration. Found insideHypernatremic, hypovolemic dehydration. • Calculation of freewater deficit, solute fluid deficit, solute sodium deficit, solute potassium deficit, ... In response to hypernatremia-induced hypertonicity in the extracellular compartment, brain cells produce osmoles using amino acids and organic solutes. Rapid fall in extracellular tonicity causes movement of water in brain cells causing brain edema and morbid neurological complications. In cases of hypernatremia caused by sodium overload, sodium-free intravenous fluid (eg, 5% dextrose in water) may be used, and a loop diuretic may be added. Dehydration can be classified according to serum sodium concentration into hypernatremic, hyponatremic, or isonatremic dehydration.
