ABSTRACT
Intraoperative neuromonitoring is a critical tool for prevention and detection of neurological compromise during spinal surgeries. We report a case of a 14-year-old female who experienced an intraoperative loss of motor evoked potentials (MEPs) on the left lower limb during corrective scoliosis surgery. The MEPs recovered following the administration of intravenous norepinephrine. This case highlights the importance of prompt intervention and vigilant neuromonitoring to optimize patient outcomes.
