Which method can be used to directly manage elevated ICP?

Performing a craniectomy is a direct surgical intervention aimed at managing elevated intracranial pressure (ICP). This procedure involves removing a portion of the skull to allow for brain expansion and to relieve pressure. When ICP rises significantly to critical levels, it can cause serious complications, including brain herniation and death. A craniectomy provides immediate space for the swollen brain, which can reduce the pressure and potentially save the patient's life.

Medications that promote hydration and encouraging low sodium intake are more supportive or indirect measures for dealing with elevated ICP. They do not address the underlying cause of the increased pressure directly. Increasing physical therapy is beneficial for rehabilitation but does not impact the management of ICP. In contrast, a craniectomy is a definitive surgical approach that directly alleviates the pressure exerted on the brain.
