Abstract

Intraoperative electroencephalography (EEG) is increasingly used to monitor the depth of anesthesia and a range of other perioperative indications. While processed EEG indices offer a convenient numerical representation, exclusive reliance on these values can obscure clinically significant findings. Discordance between the numerical index and the raw EEG or density spectral array (DSA) may arise due to artifacts, patient-specific neurophysiology, or pharmacologic effects. This article highlights common sources of such discordance, illustrated through clinical examples, and emphasizes the importance of integrating raw EEG interpretation and DSA analysis into routine intraoperative monitoring.

解读术中脑电图：超越原始脑电图和密度谱阵列的重要作用。

术中脑电图（EEG）越来越多地用于监测麻醉深度和一系列其他围手术期指征。虽然经过处理的脑电图指数提供了方便的数值表示，但完全依赖这些值可能会模糊临床重要的发现。数字指数与原始脑电图或密度谱阵列（DSA）之间的不一致可能是由于伪影、患者特定的神经生理学或药理作用引起的。本文通过临床实例强调了这种不一致的常见原因，并强调了将原始脑电图解释和DSA分析整合到常规术中监测中的重要性。
