title: [Evoked potential monitoring in an operation of neurosurgery].
abstract: In the neurosurgical field, the evoked potential is employed for the monitoring of intraoperative nerve function. During evoked potential monitoring, surgical manipulation-related nerve dysfunction is detected, and functional localization/nerves in the cerebral cortex are identified to prevent postoperative neurological complications. It is important to reduce the contact resistance to 2 kOmega or less on the application of plate electrodes used for recording and prevent noise by bundling electrode leads, to ensure a stable evoked potential during surgery. In our laboratory, intraoperative monitoring, such as ABR to prevent auditory disturbance, SEP to detect cerebral ischemia, cortical SEP and MEP to prevent motor paralysis, and evoked electromyography to identify/maintain the cranial nerves including the facial, trigeminal, oculomotor, and abducens nerves, is performed based on requests from the Department of Neurosurgery.
