Traumatic brain injury patients require what type of fluid resuscitation to maintain cerebral perfusion compared with other patients?

• A. Less aggressive
• B. Same as others
• C. Moderate
• D. More aggressive

Answer: (D)

Maintaining cerebral perfusion pressure is essential in traumatic brain injury because the brain’s blood supply must be kept adequate to prevent secondary damage. CPP depends on mean arterial pressure minus intracranial pressure, and after TBI the ICP can rise and autoregulation may be impaired, making the brain more vulnerable to drops in blood flow. To protect brain tissue, clinicians often push resuscitation more aggressively to sustain a higher MAP and thus adequate CPP, especially in the early phase, while still balancing the risk of fluid overload. This approach contrasts with being less aggressive, which could allow dangerous hypotension, or with moderating too much, which might fail to maintain perfusion.
