脑电图分析方法在麻醉监测中应用的发展现状

A Review of the Application of Electroencephalogram In Detecting Depth of Anesthesia

麻醉可以抑制病人对伤害刺激的反应,是外科手术不可缺少的步骤,但是麻醉同样会给病人造成严重后果。目前临床上迫切需要一种能保证高质量麻醉的麻醉监护技术,科学工作者们也纷纷展开研究,希望从各种医学信号中找到表征麻醉深度(Depthofanesthesia,DOA)的参数。脑电图(Electroencephalogram,EEG)信号作为检测大脑皮层活动的最主要信号,在目前麻醉深度监测研究中处于主导地位。本文中,我们系统地回顾了EEG应用于麻醉深度监测所取得的成就,并对今后可能的发展方向作了一些展望。

Anesthesia as a necessary procedure in the process of surgical operation could restrain the response of patients to the damage stimulation; However, improper anesthesia could also result in severe misfortune for patients. At the present time, one kind of monitor technology assuring highly effectual anesthesia is exigently required in clinical practice and many researchers have actively undertaken investigations to seek the parameters predicting the depth of anesthesia （DOA）. Electroencephalogram （EEG） assumes a dominant position in the current researches on detecting the depth of anesthesia. In this paper, the achievements of detecting the depth of anesthesia by means of EEG are systematically reviewed and the potentials are anticipated.
