The effects of anaesthesia with sufentanil 15 micrograms kg-1, air and oxygen on the electroencephalograph were studied in 12 patients before and after cardiopulmonary bypass. The e.e.g. responses were characterized by high voltage, slow delta waves. Although the mean power in the delta band declined with time, the contribution of delta power to total power in the frequency range 0.5-40 Hz remained constant until the onset of cardiopulmonary bypass. Sharp waves of uncertain neurophysiological significance were seen. They were not associated with clinical signs of epileptic activity. The use of the e.e.g. response as a monitor of "depth of anaesthesia" during high-dose opioid anaesthesia may become possible.
在12例患者体外循环前后，研究了15微克/千克舒芬太尼、空气和氧气麻醉对脑电图的影响。脑电图反应的特征是高电压、慢δ波。虽然δ波段的平均功率随时间下降，但在体外循环开始前，δ功率在0.5 - 40赫兹频率范围内对总功率的贡献保持恒定。观察到具有不确定神经生理意义的尖波。它们与癫痫活动的临床体征无关。在高剂量阿片类药物麻醉期间，将脑电图反应用作“麻醉深度”监测指标可能成为可能。
