Bispectraalanalyse van het elektro-encefalogram: een nieuwe methode van bewustzijnsregistratie tijdens anesthesie

- Until recently, no measure was available that provided objective and reproducible information on the level of consciousness in patients under general anaesthesia.

- Several decades of research to find a reliable measure for determining the depth of anaesthesia has now led to the clinical introduction of the bispectral index scale (BIS), a parameter derived from the electroencephalogram.

- Implementation of the BIS-monitor in anaesthetic practice leads to a reduced use of hypnotic agents, a more rapid recovery phase and possibly a reduced incidence of awareness.
