What is the primary goal in managing intracranial pressure?

• A. Increase metabolic demands
• B. Decrease metabolic demands
• C. Increase cerebral perfusion pressure
• D. Decrease oxygen delivery to the brain

Answer: (B)

When intracranial pressure is a concern, the most effective first move is to reduce the brain’s metabolic needs. The brain’s metabolic activity drives blood flow to supply oxygen and glucose. If metabolism is high, cerebral blood flow increases, adding more volume inside the rigid skull and raising ICP. By lowering metabolic demand—through adequate analgesia and sedation, temperature control, seizure prevention, and minimizing agitation—you reduce cerebral blood flow and volume, which helps lower ICP and stabilizes cerebral perfusion.

Increasing metabolic demands would worsen ICP, and increasing cerebral perfusion pressure without addressing the elevated pressure can worsen brain edema. Reducing oxygen delivery would harm brain tissue, not help it.
