No specific anesthesia is recommended, but techniques should be used to increase brain relaxation and minimize brain retraction. Hyperventilation of a pCO2 of 25 to 30 will decrease the vascular compartment. Mannitol infusion will decrease the extracellular space. Spinal drainage is used occasionally in the absence of large tumors or increased intracranial pressure and hydrocephalus.
