title: [Use of controlled hyperventilation in the treatment of comatose patients with cranial injuries].
abstract: Controlled hyperventilation is a recognized method by which it is possible to reduce the intracerebral blood volume and thus the intracranial pressure (ICP). In the review, the physiological conditions involved in the regulation of ICP are illustrated, particularly in connection with acute cranial traumata and effect of controlled hyperventilation in these situations is discussed. Controlled hyperventilation is recommended in the hyperacute phase for all patients with cranial trauma prolonged impairment of consciousness (Glasgow Coma Scale less than 7 for more than 30 minutes) and other clinical evidence of expanding space-occupying intracranial process. Prolonged hyperventilation is recommended for younger patients as these have most frequently hyperaemia and retained CO2 reactivity and for patients with predominantly cortical lesions as assessed by CT scanning. Caution in the employment of hyperventilation is advised in elderly patients, severely traumatized patients and late in the course of cerebral trauma.
