Measurement and control of neuromuscular blockade and depth of anaesthesia

The paper considers control problems for neuromuscular blockade and depth of anaesthesia. The control system is intended to be used in controlling the main parts of general anaesthesia. The applied measurement techniques, experimental conditions and control strategies are presented. The results of a study with 31 patients for the control of neuromuscular blockade, and first trials for 6 patients for the control of depth of anaesthesia are listed.
