Conception d'une interface cerveau-ordinateur pour une meilleure surveillance des réveils peropératoires au cours d'une anesthésie générale

Sébastien Rimbert 1, 2
Abstract : Each year, several million of general anesthesia are realized in France. A recent study shows that, between 0.1-0.2 % of patients are victims of intraoperative awareness. This kind of awakening could cause post-traumatic syndromes for the patient. Unfortunately, today, no monitoring system is able to avoid the intraoperative awareness phenomenon. Interestingly, if there are no subject's movement due to curare, an electroencephalographical study of the motor cortex can help to detect an intention of movement. The dynamic study of motor cerebral activity during general anesthesia is essential if we want to create a brain-computer interface adapted to the detection of intraoperative awareness. The goal of this thesis is first, to realize a feasibility study. To this end, a clinical protocol is built to allow EEG data recording during general anesthesia with propofol. Then, the development of temporal analysis specific methods allows to quantify patterns of desynchronization and synchronization phases observed in delta, alpha and beta frequency bands. This will result in the creation of this interface.
