Which treatment is used to reduce increased intracranial pressure?

• A. Mannitol, hypertonic saline, and osmotherapy
• B. Antidepressants and diuretics
• C. Mannitol, hypertonic saline, and hyperventilation
• D. Sedatives only

Answer: (A)

The key concept is lowering intracranial pressure with osmotic therapy. Mannitol and hypertonic saline are the main osmotic agents used to reduce ICP. They raise the osmolality of the blood, pulling water out of swollen brain tissue and back into the vascular space, which shrinks cerebral edema and lowers pressure inside the skull. The term osmotherapy covers both of these agents, making it the most effective and standard approach for acutely reducing ICP. Hyperventilation can transiently lower ICP by causing cerebral vasoconstriction, but it’s typically a short-term measure with risks if used long term, so it isn’t the primary, sustained treatment. Antidepressants and diuretics don’t directly address increased ICP, and sedatives alone don’t reduce ICP effectively. Therefore, the option describing osmotherapy with mannitol and hypertonic saline best reflects the treatment to reduce increased intracranial pressure.
