Hypernatremia is potentially life threatening and is caused by imbalances in water and sodium that occur from either water loss or sodium gain often in the presence of inadequate water intake. Body Weight kg Animal type. Fluid rate with volume deficit corrections.
The resultant hyperosmolarity if acute or severe can result in rapid shifts of water from the intracellular to extracellular space causing intracranial hemorrhage and neurologic changes. This can be incorrect in patients with signfiicant weight gain or loss especially from fluid sources. 1 kg of water 1000 mL.
