Randomized Controlled Trial Comparative Study[Effects of volatile anesthetics on cortical somatosensory evoked potential and Bispectral index].
To improve the anesthetic environment in monitoring short-latency somatosensory evoked potentials (SSEP) during operation, we compared the effects of different anesthetics on SSEP and Bispectral index (BIS), which aim to select suitable anesthetics and their doses used intraoperatively. ⋯ The effects of three volatile anesthetics on SSEP and BIS are significant in dose-dependent manner. Anesthetic regimen of 0.75 MAC isoflurane for intraoperative cortical SSEP monitoring may be optimal. It seemed that the correlation between BIS and short-latency SSEP was poor, although both are associated with the effects of anesthetics on cerebral cortex.
