Feedback control of anaesthesia.
Feedback control of anaesthesia can improve the quality of patient care while reducing the administration and cost of anaesthetic drugs. Systems have been available for several years to control blood pressure and neuromuscular blockade. Control of anaesthetic depth has been reported using the median frequency of the electroencephalogram. Recently, the monitoring of anaesthetic depth using the bispectral index or auditory evoked potentials has greatly improved feedback control of the depth of anaesthesia.
