A casualty with traumatic brain injury should have secondary brain injury prevented by maintaining adequate:

• A. Oxygenation
• B. Hydration
• C. Temperature
• D. Pain Control

Answer: (A)

Secondary brain injury comes from harm to brain tissue after the initial trauma, driven most directly by a lack of oxygen. The brain is highly sensitive to hypoxia, and when oxygen delivery falls, energy fails, cells die, and swelling and further injury can escalate. Because of this, keeping oxygenation adequate is the most effective way to prevent additional brain damage in a casualty with brain injury—usually by ensuring the airway is clear and providing supplemental oxygen to maintain normal oxygen saturation. Hydration and fluid status matter for sustaining cerebral perfusion, but they don’t address the immediate risk of hypoxia as directly as ensuring sufficient oxygen delivery. Temperature management helps limit metabolic demands, and pain control reduces stress responses that can worsen brain injury, but neither tackles the critical need for oxygen to the brain as directly as maintaining adequate oxygenation.
