Why is sedation used in the management of traumatic brain injury?

• A. Increase blood pressure.
• B. Treat infection.
• C. Slow healing.
• D. Manage agitation and discomfort in patients with TBI.

Answer: (D)

Sedation is used in traumatic brain injury to control agitation and discomfort. When a patient is anxious, in pain, or moves ramptly, sympathetic activation raises heart rate and blood pressure and increases metabolic demand and ICP, which can worsen brain injury. By calming the patient, reducing pain, and minimizing movement, sedation lowers metabolic demand, helps protect cerebral perfusion and intracranial pressure, and makes it safer to manage ventilation and perform neuromonitoring. It’s not about increasing blood pressure, treating infection, or slowing healing—the goal is to keep the brain in a more stable, protected state by reducing agitation and discomfort.
