Abstract: This disclosure relates to a system that comprises means for obtaining a signal representative of the electrocortical activity of the patient, means for analyzing this signal in order to derive from it a signal of depth of anaesthesia, means for monitoring the value and development over time of this signal of depth of anaesthesia, these means being associated with means for calculation of control commands of the injection means, in order to automatically bring the signal of depth of anaesthesia to below a predetermined value during at least one predetermined period of time, in that the means for injection of anaesthetics comprise first means for injection of a hypnotic and second means for injection of a morphinomimetic, in that the means for calculation of the control commands of the injection means comprise means allowing an operator to input a type of induction of anaesthesia chosen from a group of types of induction that differ in terms of the initial concentration of hypnotic, and in that the means for i

Abstract: A system comprising means for obtaining a signal representative of the electrocortical activity of the patient, means for analyzing this signal in order to derive from it a signal of depth of anaesthesia, means for monitoring the value and development over time of this signal of depth of anaesthesia, these means being associated with means for calculation of control commands of the injection means, in order to regulate automatically in closed loop the signal of depth of anaesthesia in a predetermined range around a target value, and in that the means for injection of anaesthetics comprise first means for injection of a hypnotic that receive control commands at a first frequency, and second means for injection of a morphinomimetic that receive control commands at a second frequency higher than the first frequency.

Abstract: This system is characterized in that it includes means (2) for acquiring a signal representative of the electrocortical activity of the patient (1), means (3) for analyzing this signal in order to extract therefrom an anesthetic depth signal, means (4, 5, 6) for tracking the value and the time-dependent evolution of this anesthetic depth signal, associated with means (4, 5, 6) for computing control signals for controlling the injection means, in order to automatically bring the anesthetic depth signal to below a predetermined value during at least one predetermined period of time, in that the means for injecting anesthesia agents comprise first means (7) for injecting a hypnotic agent, and second means (8) for injecting a morphinomimetic agent, in that the means for computing control signals for controlling the injection means comprise means for inputting by an operator a type of anesthesia induction selected from a set of induction types which differ by the initial concentration of hypnotic agent and in that
