Excerpt
Monitoring of motor evoked potentials (MEPs) can provide information about the functional integrity of a motor pathway and, therefore, has been widely used during surgery in which a motor pathway is at risk of injury, including craniotomy, spine/spinal surgery, and thoracic or thoracoabdominal aortic aneurysm (TAA or TAAA) surgery [

2]. Because myogenic MEPs are very sensitive to suppression by anesthetic agents and neuromuscular blockade, careful attention should be paid to anesthetic management during monitoring of MEPs. In general, total intravenous anesthesia with propofol and opioids is used, although ketamine-based anesthesia may be applied in cases in which recording of myogenic MEPs is not reliable because of suppression by anesthetic agents or influence by preoperative motor dysfunction. …
