Adaptive and intelligent control in anesthesia

The application of advanced control techniques to drug-induced unconsciousness and muscle relaxation in operating theaters is described. A brief survey of other simple control applications to anesthesia is given, and the use of generalized predictive control and fuzzy logic control for muscle relaxation are discussed. Various attempts have been made to control unconsciousness automatically, but an expert system advisory approach based on data fusion for clinical signs and online monitoring is emphasized. Extensions of both adaptive and intelligent control techniques for multivariable anesthesia are described.<>
