Abstract
The electroencephalographic signatures of anesthetic drugs relate to a specific set of action mechanisms within the neural circuits. During intraoperative care, the recognition and correct interpretation of the EEG spectrogram can be used as a tool to guide anesthetic administration. For example, loss of alpha power during propofol anesthesia may be a sign of lighter level of hypnosis and/or of an increase in nociceptive inputs. We describe a case report of inadvertent interruption of propofol delivery that was first detected by changes in the electroencephalogram spectrogram.
摘要
麻醉药物的脑电图特征与神经回路中特定的一组作用机制有关。在术中护理期间，可将 EEG 频谱图的识别和正确解释用作指导麻醉给药的工具。例如，异丙酚麻醉期间α波功率的丧失可能是催眠程度较轻和/或伤害性输入增加的迹象。我们描述了一个异丙酚输注意外中断的病例报告，该中断首先通过脑电图频谱图的变化检测到。
