Which posture is used to manage intracranial pressure?

• A. Fowler's Position
• B. Trendelenburg
• C. Left Lateral Position
• D. Reverse Trendelenburg's Position

Answer: (D)

Elevating the head reduces intracranial pressure by boosting venous drainage from the brain. In a reverse Trendelenburg posture, the head is higher than the feet, using gravity to help blood flow away from the cranial vault through the jugular veins. This lowers cerebral blood volume in the skull and thus lowers ICP, while helping preserve cerebral perfusion if blood pressure is maintained. Tilting the head down (Trendelenburg) would push more blood toward the brain and raise ICP, and the other positions don’t optimize venous outflow from the brain to the same extent. So, the posture that best helps manage intracranial pressure is head-up with the feet lower—the reverse Trendelenburg position.
