The practical value of the electroencephalogram during anaesthesia

  • E. A. Gain


Because of the inadequacy of the conventional signs of anaesthesia during anaesthesia with today’s techniques and agents;, it is suggested that the electroencephalogram is a useful guide in protecting the poor risk patient, particularly the cardiac patient, against overdose. This is especially so during the induction phase because of the “lag-phenomenon.” Several examples of the value of the electroencephalogram during anaesthesia and extracorporeal circulation, and as a prognostic aid following cerebral hypoxia have been presented It is also suggested that the electroencephalogram is a valuable teaching aid and that it is useful as a measure of the efficiency of cardiac massage during the treatment of cardiac arrest

A cause du manque de précision des signes conventionnels ďanesthésie au cours de ľanesthésie qui se pratique aujourďhui avec les agents et les techniques modernes, ľélectroencéphalogramme devient un guide précieux pour protéger les grands malades contre un surdosage éventuel de substances anesthésiques et plus particulièrement les cardiaques. Cette situation se présente surtout au cours de ľinduction à cause du phénomène ďaction à retardement Nous avons donné plusieurs preuves de la valeur de ľélectroencéphalogramme durant ľanesthésie, durant la circulation extra-corporelle et comme moyen de pronostic à la suite ďhypoxie cérébrale. Ľélectroencéphalographie s’avère également ďun précieux secours pour ľenseignement de même que pour déterminer ľefficacité du massage cardiaque durant le traitement de ľarret cardiaque.
