Monitoring of intracranial pressure (ICP) is indicated in selected patients with: • Severe head injury • Subarachnoid hemorrhage graded III, IV, or V preoperatively • Reye’s syndrome or similar encephalopathies • Hydrocephalus • Intracranial hemorrhage • Miscellaneous problems when drainage is to be used as a therapeutic maneuver Monitoring can also be used to evaluate the status pre- and postoperatively for space-occupying lesions.
