Abstract

Intraoperative monitoring of motor evoked potential (MEP) is a modality for preventing spinal cord injury during spinal surgery. However, inhalation anesthetics and muscle relaxants depressing MEP responses, must be restricted for monitoring MEP. Therefore, anesthetic management needs careful attention for preventing recall and unintentional movements during surgery and special techniques for monitoring adequate MEP. We report here on 7 cases of successful intraoperative monitoring of MEP with total intravenous anesthesia using propofol and remifentanil for scoliosis surgery in adolescent patients.
