The research group medical control at the Universities of Rostock (Germany) and Wismar has developed an assistant system for anesthesia to support anesthetists in controlling and maintaining the state of the patient in the operating theatre. The main objectives during general anesthesia are adequate level of hypnosis, analgesia, relaxation, and stable vital functions. During the last 20 years many controllers for the automatic drug delivery in anesthesia were developed. Starting with controllers for keeping a constant level of neuromuscular blockade, controllers for the hypnosis and analgesia were performed. Our research group developed a control system with an adaptive Generalized Controller for the neuromuscular blockade, a fuzzy controller for the control of the level of hypnosis and a fuzzy-system for analgesia control. The current contribution summarizes two studies, the MIMO control of the neuromuscular blockade and the depth of anesthesia which was done with 22 patients and the MIMO control of the depth of anesthesia and the level of analgesia. A model-based predictor for the level of neuromuscular blockade (NMB), to predict the level of NMB after stopping the drug infusion was integrated as a new feature for improving the clinical benefit .

“…The evoked potentials are indicators for the responsiveness of the central nervous system during anaesthesia. For example, auditory-evoked potentials were used in different applications [58,59]. A new idea to derive parameters from EEG signals was developed by the research group led by Dumont; with the help of wavelet analysis a more robust parameter may be developed perspectively [60,61].…”

The main goals of general anaesthesia should include (not exclusively) adequate hypnosis, analgesia and maintenance of vital functions. In addition, neuromuscular blockade (NMB) may be needed for a number of surgical procedures. Patient safety and cost reductions via the minimization of drug consumption and the shortening of post-operative recovery represent some of the main issues and motivations of automation of anaesthesia.Since the early eighties engineers and physicians joined efforts towards the development of sophisticated closed-loop control systems for drug delivery in the operating theatre and post-operatively.First, this paper should be seen as a review about the automatic drug delivery in anaesthesia. A summary is given about the methods of measurement, modelling and general progress of closed-loop control systems in anaesthesia. In particular, the development of the 'Rostock assistant system for anaesthesia control (RAN)' is also described. This system has been developed during the last 15 years at the University of Rostock and various systems and control-based ideas have been integrated since. With this system the multiple-input-multiple-output (MIMO) control of the depth of hypnosis and NMB has been shown to be possible as well as the closed-loop control of a deep arterial hypotension. Promising results have already been obtained from a first study, which has so far included as many as 22 patients using MIMO control.

Abstract-The main goals of general anesthesia are adequate hypnosis, analgesia and maintenance of vital functions. For some special kinds of operations neuromuscular block is essential.Furthermore the patient safety and cost reduction as a case of minimized drug consumption and shortened postoperative recovery phases are part of the main issues to motivate automation in anesthesia.Since the beginning of the eighties engineers and physician are working together in the field of the development of closed-loop systems for drug delivery. The work gives a short overview about the development of the automation in drug delivery systems over the last years without the claim of completeness and expressed the much more vision.
