Median nerve EMG to monitor neuromuscular function during surgery
Official title: Comparative Examination of Ulnar and Median Nerve Electromyography Examinations to Monitor Intraoperative Neuromuscular Function
Run by University of Debrecen · NCT07571395 · Data updated 2026-11-12
This study tests whether measuring the median nerve’s muscle response can help track the effect of muscle relaxants during elective surgeries.

Is this trial a fit for you?
✓Likely a good fit
Adults (ASA I–III) undergoing elective surgery requiring muscle relaxation with both arms accessible for monitoring.
✕Probably not a fit
Patients with neuromuscular disorders, arm innervation problems, musculoskeletal deformities, or other exclusion criteria may not benefit from this approach.

What this trial studies
This observational study explores using electromyography of the median nerve at the wrist to monitor neuromuscular function during anesthesia. It compares this approach with the standard ulnar nerve monitor to see if the median nerve provides reliable information across different surgeries. Eligible participants are adults undergoing elective procedures who require muscle relaxation and can have both arms accessible for monitoring. Data will be collected on the feasibility and usefulness of the median nerve monitor in guiding anesthesia and recovery.
Why it matters
Potential benefit: If successful, the median nerve monitor could offer an additional or alternative method to ensure adequate reversal of muscle relaxants and safer emergence from anesthesia.
How similar studies have gone: Some studies support neuromuscular monitoring methods, but using the median nerve is less established and thus represents a relatively novel approach.
