Why should ICP be monitored in TBI patients?

• A. Identify signs of cerebral edema and prevent further brain injury.
• B. Reduce blood glucose.
• C. Measure liver enzymes.
• D. Assess kidney function.

Answer: (A)

Monitoring intracranial pressure in severe TBI serves to detect rising pressure from cerebral edema or other mass effects and to guide timely interventions that prevent secondary brain injury. When ICP is elevated, cerebral perfusion pressure can drop, risking ischemia and herniation. Real-time ICP data allow clinicians to implement measures to lower pressure and maintain adequate cerebral blood flow, such as appropriate positioning, ventilation and oxygenation, osmotic therapy, sedation, and, if needed, CSF drainage or surgical decompression. This purpose is distinct from assessing metabolic or organ function, such as blood glucose, liver enzymes, or kidney function, which are not the primary reasons for ICP monitoring.
