Which head position is recommended to help manage cerebral edema in a patient with traumatic brain injury?

• A. Keep neck in neutral alignment
• B. Elevate head to 30 degrees
• C. Place in Trendelenburg
• D. Extend the neck

Answer: (B)

Head position influences cerebral venous drainage and intracranial pressure. In cerebral edema from traumatic brain injury, elevating the head helps gravity drain venous blood from the brain, reducing intracranial pressure. Keeping the head of the bed about 30 degrees while keeping the neck in a neutral, midline position optimizes venous outflow and avoids kinking of vessels. Placing a patient in Trendelenburg (head down) increases cerebral blood volume and ICP, making it worse. Extending the neck can also impede venous return and raise ICP, whereas neutral alignment supports drainage. So elevating the head to 30 degrees is the recommended approach.
