Motor threshold-tracking transcranial electrical stimulation with double and single train stimulation under sevoflurane anesthesia.
Introduction and goals: Intraoperative motor evoked potentials (MEP) are commonly used in spinal surgery, including scoliosis correction. Inhaled anesthetics cause significant depression of the MEP, especially in the presence of an initial neurological deficit, as a result of that the search for optimal stimulation parameters to reduce this problem is an important issue. The aim of the study was to compare the effectiveness and the threshold of the transcranial electrical MEP obtained by automatic tracking with single and double train stimulation.
