A study was conducted comparing the incidence with which the N2/P2/N3 was obtained after flash VEP in 3 groups: anterior visual pathway lesions, non-tumor craniotomies and non-cranial surgery. These groups allowed evaluation of the effects of anesthesia, visual pathway lesions and craniotomy on the stability of the flash VEP. It was found that the latency was not significantly affected in the 3 groups, whereas the incidence of obtainable peaks and the amplitudes were adversely affected by anesthesia, cranial surgical manipulation and especially by the presence of a visual pathway lesion. These adverse effects were so marked that the application of flash VEP for intraoperative monitoring seems of little use.
开展了一项研究，比较了3组患者在闪光视觉诱发电位（VEP）后获得N2/P2/N3的发生率：前视觉通路病变组、非肿瘤开颅手术组和非颅脑手术组。这些组有助于评估麻醉、视觉通路病变和开颅手术对闪光VEP稳定性的影响。结果发现，3组患者的潜伏期均未受到显著影响，而可获得峰值的发生率和振幅受到麻醉、颅脑手术操作的不利影响，尤其是视觉通路病变的影响。这些不利影响非常明显，以至于闪光VEP在术中监测中的应用似乎用处不大。
