Hypertonic solution

More solutes than intracellular fluid, fluid shifts OUT of cells, used for hypovolemia/vascular expansion, increase urine output (post op), DKA. higher solute concentration causes the osmotic pressure gradient to draw water out of cells, increasing extracellular volume. These fluids are often used as volume expanders and may be prescribed for hyponatremia (low sodium). They may also benefit patients with cerebral edema.
