Summary
Accelerating sensory evoked potentials (EPs) recording in neurosurgery is crucial for effective intraoperative neuromonitoring (IONM). Personalized adjustments to recording parameters can significantly reduce EP acquisition time, improving patient safety.
Area of Science:
- Neurosurgery
- Neurophysiology
- Medical Technology
Background:
- Sensory evoked potentials (EPs) monitor neurological function during surgery to prevent complications.
- Current EP recording methods are lengthy, potentially limiting intraoperative neuromonitoring (IONM) effectiveness.
- Early detection of reversible functional deficits via EPs can guide surgical decisions.
Purpose of the Study:
- To review personalized approaches for accelerating sensory EP recording during IONM.
- To discuss challenges and solutions for implementing faster EP acquisition.
- To explore future developments in optimizing IONM procedures.
Main Methods:
- Review of personalized parameter selection in IONM for somatosensory, visual, and brainstem acoustic EPs.
- Analysis of differences between IONM and clinical neurophysiology (CN) to optimize EP recording.
- Focus on improving signal-to-noise ratio (SNR) for faster EP acquisition.
Main Results:
- Personalized adjustments to electrode placement, filters, and stimulation rates can significantly speed up EP recording.
- Optimizing parameters can improve the signal-to-noise ratio (SNR) for EPs.
- This personalized approach offers a substantial acceleration of EP acquisition, potentially several times faster.
Conclusions:
- Personalized EP recording strategies are vital for efficient IONM.
- Overcoming implementation barriers is key to wider adoption of accelerated EP techniques.
- Future developments may further enhance the speed and efficacy of intraoperative neurophysiological monitoring.
