The influence of anaesthesia on intraoperative motor evoked potential changes during Neurosurgery

Background: Intraoperative neurophysiologic monitoring has been demonstrated to alert the surgical team to potential injury and can also be used to detect injuries. The purpose of this study was to compare the effects of Sevoflurane and Propofol combined with Remifentanil on Motor Evoked Potentials from cranial nerves and lower limbs during comparable depth of anaesthesia, guided by bispectral index (BIS).
