In authors' opinion, the more precise methods for controlling the depth and efficiency of general anesthesia are those which are based on the direct control over the intraoperative status of the central nervous system which reflects the time course of the status in question. Whether monitoring of the early components of somatosensory evoked potentials could be used for multimodality anesthesia was analysed. As high as 50% or lower decreases in the amplitude of the complex N19-P23 were typical of adequate defense, irrespective of anesthesias. The authors provide evidence for the efficiency of their procedure for controlling the depth and efficiency of general anesthesia. Some electroencephalographic phenomena of anesthesia were analysed with computed monitoring. The authors showed that there was a relative value of such signs of inadequate anesthesia as interhemispheric asymmetry by the leading spectral frequency and the power index of deep rhythms. Despite the procedure used (neuroleptic analgesia, ataralgesia, inhalation anesthesia, etc.), the effective anesthesia exhibited pronounced power peaks, otherwise there was a chaotic activity of the central nervous system. The physiological and clinical values of the phenomena detected are discussed in the paper.
作者认为，更精确控制全身麻醉深度和效果的方法是基于对反映相关状态时间进程的中枢神经系统术中状态进行直接控制。分析了体感诱发电位早期成分监测是否可用于多模式麻醉。无论麻醉方式如何，复合波N19 - P23波幅降低50%或更低是充分麻醉的典型表现。作者提供了其控制全身麻醉深度和效果程序有效性的证据。通过计算机监测分析了一些麻醉的脑电图现象。作者表明，以主导频谱频率和深度节律功率指数表示的半球间不对称等麻醉不足迹象具有相对价值。无论采用何种程序（神经安定镇痛、无痛麻醉、吸入麻醉等），有效麻醉均表现出明显的功率峰值，否则中枢神经系统会出现混乱活动。本文讨论了所检测现象的生理和临床价值。
