Diffuse brain swelling on imaging implies which treatment considerations?

• A. Increased risk of intracranial hypertension; requires measures to lower ICP (positioning, sedation, osmotherapy, ventilation adjustments)
• B. Decreased intracranial pressure; no intervention needed
• C. No effect on treatment plan
• D. Spontaneous resolution without change in management

Answer: (A)

Diffuse swelling signals that the brain is at risk for intracranial hypertension, which can compromise blood flow and brain tissue. The treatment focus is to prevent and reduce high ICP while preserving adequate cerebral perfusion. Practical steps include elevating the head of the bed about 30 degrees with the neck in a neutral position to aid venous drainage, ensuring adequate oxygenation and blood pressure, and providing sedation and analgesia to lower metabolic demand. Ongoing osmotherapy with hypertonic saline or mannitol helps draw fluid out of swollen brain tissue. Ventilation should maintain normal or slightly reduced PaCO2 to optimize cerebral blood flow, with cautious hyperventilation used only temporarily if there is acute herniation risk. If ICP remains high despite these measures, invasive options such as CSF drainage via a drain may be considered. Maintaining overall physiological stability—temperature, glucose, and body fluids—is also important.
