[Place of neuroleptics in neurosurgical anesthesia-resuscitation]

The interest of neuroleptics in neurosurgery should be examined in the light of physiopathological and pharmacological data concerning cerebral circulatory autoregulation and intracranial pressure. The fairly favourable conclusions permit one to consider their wide use justified, especially, by the feeble hypnogenic effects, without any marked disturbance of the E.E.G., associated with an anticatecholaminergic and stabilizing effect on the autonomic nervous system. They therefore occupy a place of choice, in particular during induction of anesthesia in high risk patients, during operations requiring neurological or continuous E.E.G. investigations, in surgery of intracranial aneurysm and, finally, to obtain sedation and post-operative autonomic control.
