Motor evoked potential（MEP）monitoring is more affected by anesthetics than any other form of neurophysiologic intraoperative monitoring. Anesthetics attenuate MEP responses in a dose-dependent manner. Anesthesiologists need to be familiar with anesthetic management in MEP monitoring. Total intravenous anesthesia using propofol and opioids（e.g., remifentanil and fentanyl）may be the optimal anesthetic regimen for MEP monitoring. Inhaled anesthetics（e.g., sevoflurane and desflurane）may also be used if initial baseline MEP can be measured with high reproducibility. The depth of anesthesia should be kept at a constant level based on EEG monitoring and a neuromuscular monitor.
