Abstract

Since one of the earliest systematic observations of the physiologic effects of anaesthetic agents of John Snow in 1847 our interest of measures of the level of anaesthesia has persisted and a variety of approaches and technologies have meanwhile been introduced and utilized. Today, the practice of anaesthesia remains one of the safest and most effective in medicine. So why monitor the central nervous system (CNS)? Like all new technologies, CNS monitoring devices will certainly add something to the cost of delivering anaesthesia. On the other hand, there is no doubt that significant unpredictability and uncertainty still exists in the delivery of anaesthetic drugs. This is reflected in the variety of suggested dosing regimens, especially in intravenous anaesthesia. Some patients still suffer intra-operative awareness and may consecutively develop posttraumatic stress disorder,1 whereas others still have prolonged recovery due to relative overdosing even with otherwise short-acting drugs.
