A Rare Presentation of Motor-Evoked Potential Stimulation-Induced Intraoperative Seizure in a Pediatric Patient

Intraoperative neurophysiological monitoring (IONM) is routinely used to prevent neurological morbidity during spine and spinal cord surgeries. Among all IONM techniques, transcranial motor-evoked potential (MEP) stimulation is commonly utilized. Lip and tongue bite injuries, cardiac arrhythmias, seizures and bleeding, hematoma, and minor scalp burns at the stimulation site are widely reported complications associated with MEP stimulation.[1] The incidence of intraoperative seizures following transcranial MEP stimulation is rare, ranging from 0.03 to 0.8% for spine surgery.[2] [3]
