Mechanism of action

9% saline is a hypertonic solution containing 9 grams of sodium chloride per 100 mL of water. When administered intravenously, it increases serum osmolality and draws fluid from intracellular and interstitial spaces into the vascular compartment, expanding intravascular volume and restoring electrolyte homeostasis. This mechanism is used to treat severe hyponatremia, cerebral edema, and hypovolemic shock.
