1913年Pravdish-Nemisky发现用电刺激狗的坐骨神经可以在皮层脑电图中记录到一个尖锐的波。1947年Dawsons首先设计了诱发电位的检测方法,1958～1960年一些作者报告健康人和病人诱发电位的检测结果。随微电脑技术发展,通过大量动物实验及临床研究,发现它对临床麻醉、脊柱及神经外科手术监测、判断脑外伤及缺O_2性昏迷病人的预后均有重要作用。本文仅就这一方面的近况作一概述。 1913 Pravdish-Nemisky found that electrical stimulation of the dog’s sciatic nerve can record a sharp wave in the cortical EEG. In 1947 Dawsons first designed the detection method of evoked potentials. From 1958 to 1960, some authors reported the detection results of the evoked potentials in healthy people and patients. With the development of microcomputer technology, through a large number of animal experiments and clinical studies, it found that it plays an important role in clinical anesthesia, spine and neurosurgery monitoring, judging the prognosis of patients with traumatic brain injury and O_2 -based unconsciousness. This article only summarizes the current situation in this area.
