Abstract

The design and application of a closed-loop controller for the infusion of the muscle relaxant atracurium are described. The controller uses a processed electromyography system for the feedback signal and a new control algorithm, for which a flowchart is given. Initial clinical testing in the operating room demonstrated excellent control characteristics. The algorithm settled within 15 min with very little variation in the state of relaxation. Each person had his or her own settling point, but this was always within 7-12% of control, which produced acceptable clinical relaxation
