Somatosensory Evoked Potential Algorithm for Detection of Intraoperative Positional Neuropraxia

London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's115 enrolled

Overview

This study hypothesizes that an automated device using small electronic impulses can detect nerve impairment in unconscious patients.

Application of SSEP probes to bilateral ulnar and popliteal nerve areas with sensors at (1) bilateral brachial plexus (clavicles), (2) Erb's point (posterior C8 cervical spine) and (3) on forehead will permit microvolt current to to be detected and analyzed against a proprietary algorithm. Neuropraxia will be detected based on abnormalities developing in received SSEP signals.
