Abstract:

A current research project at the Automatic Control Laboratory is developing an autonomous anaesthesia system. In recent years the introduction in the clinical practice of new non-invasive monitoring techniques as well as computer controlled drug delivery devices changed radically the way anaesthetic drugs are administered. Feedback controllers might take over some of the routine tasks of anaesthesia, providing optimal drug administration profiles and leaving the anaesthetist more time to concentrate on more critical issues during surgery. In collaboration with the University Hospital in Bern and profiting from solid collaboration with industrial partners like Draeger and Aspect Medical Systems, feedback controllers were developed to regulate gas concentrations in breathing system. Subsequently, closed loop controllers to regulate blood pressure were developed and tested, which guarantee haemodynamic stability during surgical manipulation. Recently, closed loop controllers of hypnosis were designed and tested to ensure unconsciousness and absence of recall without overdosing of hypnotic drugs. In this talk the challenges and the results achieved during the project will be discussed, with special emphasis on the procedures required to cope with safety issues in Operating Theatre.
