Neurophysiologic monitoring is a diverse group of instruments that are used to monitor the central and peripheral nervous system during surgical procedures. Some are used to monitor anesthetic depth, whereas others are used by neurologists to monitor the integrity of the nervous system during surgical procedure. The goal of neurophysiologic monitoring is to have reliable, reproducible, and predictive monitors that can identify impending compromise to the neurologic system (or anesthetic) with minimal false predictive value and high positive predictive value. This allows for the identification of neurologic tissues by location and type that are at risk of compromise by vascular and/or mechanical injury. This review contains 3 figures, 8 tables, and  34 references.

ABSTRACT:Despite advances in instrumentation and the use of microsurgical techniques, neurosurgical procedures involving extensive areas of skull base or other critical areas of brain still carry significant risk for neurological injury. The use of intraoperative recording of sensory evoked potentials (SEP) has been advocated to monitor neurologic function during these major neurosurgical procedures to reduce the risk of injury to neural structures.This report summarizes our experience with intraoperative monitoring of SEP in over 200 patients, and details our findings in a group of 12 patients with skull base and posterior fossa tumours. Somatosensory evoked potentials (SSEP) were monitored in all patients, and brain stem auditory evoked potentials (BAEP) in five. While minor changes in BAEP and SSEP parameters were noted in most patients, significant changes occurred in five. Irreversible loss of BAEP in one patient was associated with complete hearing loss postoperatively. Marked, persistent alteration of both BAEP and SSEP was associated with postoperative brainstem dysfunction. No patient with stable BAEP and SSEP at the end of the procedure suffered additional neurological deficit.We conclude that intraoperative SEP monitoring may be valuable in minimizing neural injury during major neurosurgical procedures.

AbstractIntraoperative neurophysiological monitoring has achieved importance due to complexity of cranio-spinal surgical procedures being performed frequently these days. Many studies have proven a decreased neurological complication rate after its introduction. It is broadly of two types: Sensory evoked potentials and motor evoked potentials which are further sub-divided. Its use during surgery requires a controlled anaesthesia technique with no or minimal influence on its recording. Its success depends upon three way communication among the surgeon the neurophysiologist and the anaesthesiologist.
