What is the initial management step for a patient with suspected elevated intracranial pressure but intact brainstem reflexes?

• A. Aggressive ICP control with medical therapy, head-up positioning, ventilation optimization, and neurosurgical consultation for potential decompression.
• B. Immediate decompression without medical therapy.
• C. Bed rest and observation only.
• D. Hyperventilation with hypotonic fluids.

Answer: (A)

When ICP is suspected, the priority is to prevent secondary brain injury by lowering the pressure and preserving cerebral perfusion. Even with intact brainstem reflexes, the patient is at risk of deterioration, so the initial approach should be comprehensive medical management rather than waiting or jumping straight to surgery. Start with measures that reduce ICP and stabilize the patient: elevate the head of the bed to about 30 degrees to improve venous drainage; ensure the airway and breathing are optimized to achieve normal oxygenation and normocapnia (avoid hypoxia and avoid prolonged hyperventilation unless there is impending herniation); provide appropriate sedation and analgesia to decrease metabolic demand and agitation; initiate osmotic therapy (mannitol or hypertonic saline) if ICP is elevated; maintain euvolemia and adequate blood pressure to support cerebral perfusion. Involve neurosurgery early to plan for possible decompression if ICP remains high despite medical therapy. Hyperventilation with hypotonic fluids is not a routine initial strategy because it can reduce cerebral blood flow and worsen edema; immediate decompression is not indicated without first trying medical ICP control. Bed rest and observation alone would fail to address the warning signs of rising ICP.
