What is the overall goal of ICP management in moderate-to-severe TBI?

• A. To prevent secondary brain injury by controlling ICP and maintaining adequate CPP using a stepwise approach of medical and surgical therapies as indicated
• B. To maintain ICP at the highest possible level to ensure perfusion
• C. To avoid any use of osmotic therapies
• D. To eliminate all sedation during management

Answer: (A)

The goal of ICP management in moderate-to-severe TBI is to prevent secondary brain injury by keeping intracranial pressure under control and ensuring adequate cerebral perfusion pressure through a stepwise medical and surgical plan. When ICP rises, cerebral perfusion pressure (CPP = MAP − ICP) falls, which can lead to brain ischemia and further injury. So the priority is to lower or stabilize ICP while maintaining CPP in a range that supports consistent brain blood flow, typically around 60–70 mmHg in adults. Start with less invasive measures—adequate oxygenation and ventilation, appropriate sedation and analgesia, head elevation, and meticulous hemodynamic control—and escalate to medical therapies such as hyperosmolar therapy (hypertonic saline or mannitol) and CSF drainage when indicated. If ICP remains elevated despite these steps, add temporizing measures like controlled hyperventilation and, in refractory cases, consider surgical options such as decompressive craniectomy. The emphasis is on preventing secondary injury by preserving perfusion, not on keeping ICP high. Osmotic therapy and thoughtful sedation are integral parts of this approach, while avoiding them would undermine proper ICP management.
