In managing head injuries, which parameter should be monitored to prevent secondary brain injury?

• A. Central venous pressure (CVP)
• B. Intracranial pressure (ICP)
• C. Blood pressure (BP)
• D. Heart rate (HR)

Answer: (B)

Monitoring intracranial pressure (ICP) is crucial in the management of head injuries because elevated ICP can lead to secondary brain injury. Secondary brain injury occurs as a consequence of impaired cerebral perfusion, which can result from elevated ICP. By tracking ICP, healthcare providers can identify increases in pressure that might compromise brain function, allowing for timely interventions to reduce the risk of further damage. ICP monitoring aids in assessing the brain's hemodynamics and guiding treatment decisions, such as the need for hyperventilation, osmotherapy, or surgical intervention to relieve pressure. Keeping ICP within acceptable limits is vital for ensuring adequate cerebral perfusion and preserving neurological function, ultimately influencing patient outcomes after a head injury. While blood pressure, heart rate, and central venous pressure also play roles in overall hemodynamic stability, they do not directly reflect the changes in intracranial environment or brain tissue perfusion as accurately as ICP does. Therefore, monitoring ICP is specifically essential for protecting the brain from secondary injury following trauma.
