Page-!-sur-!-resumé-introduction, Le but de cette étude a été de comparer le pouvoir de discrimination du BIS ® et du qCON ® dans leur capacité à détecter les périodes d'anesthésie insuffisamment ou trop profonde durant la période d'entretien d'une anesthésie balancée comprenant un agent halogéné. Par ailleurs, nous avons analysé l'évolution de l'indice qNOX

, 2 ± 0,1% des cas, la discordance majeure. Lorsque la valeur du qNOX était élevée, la probabilité d'avoir un qCON très supérieur au BIS (> 25) était élevée.
