Summary
Intraoperative neurophysiological monitoring (IOM) uses advanced electrophysiological methods for improved surgical accuracy. This review covers IOM techniques, their limitations, and optimal use during surgery.
Area of Science:
- Neuroscience
- Anesthesiology
- Medical Technology
Background:
- Recent advancements in anesthesiology and device technology have enhanced intraoperative neurophysiological monitoring (IOM).
- IOM plays a crucial role in maintaining neurological function during complex surgeries.
Purpose of the Study:
- To review the fundamental principles of electrophysiological techniques used in intraoperative neurophysiological monitoring (IOM).
- To discuss the optimal application and alarm criteria for various IOM modalities in surgical settings.
Main Methods:
- Review of established electrophysiological methods including motor evoked potentials (MEPs), somatosensory evoked potentials (SSEPs), electroencephalography (EEG), electromyography (EMG), brainstem auditory evoked potentials (BAEPs), and visual evoked potentials (VEPs).
- Analysis of stimulation and recording parameters for each modality.
- Discussion of alarm sign criteria.
Main Results:
- The review details the principles behind MEPs, SSEPs, EEG, EMG, BAEPs, and VEPs.
- Optimal stimulation/recording methods for diverse surgical procedures are discussed.
- Criteria for identifying significant alarm signs are presented.
Conclusions:
- Electrophysiological methods are integral to modern intraoperative neurophysiological monitoring (IOM).
- While IOM techniques have improved, their utility and interpretation require careful consideration of individual surgical contexts and modality-specific limitations.
