[Cerebral Function Monitor and anesthesia].

The Monitor of Cerebral Function was employed in anaesthesia for a double purpose: as a monitor of anaesthesia, of possible complications and of overdosage that might lead to cerebral damage; a bringing up to date of the comparative data on the various anaesthetic protocols. In this manner, we were able to demonstrate the during anaesthesia application of a cerebral monitor that is well designed and easy to handle. A comparative study of hypnotic anaesthetics and those that induce neuroleptanalgesia demonstrated that, in certain cases, the same anaesthetic stability is achieved when there is an early appearance of the electric silences as when the cerebral electrical activity is only slightly modified.
