NCT06754995

Brief Summary

The goal of this observational study is to investigate the applicability of 100 Hz tetanic stimulation with an electromyography device in the exclusion of postoperative residual neuromuscular block. The aim is to determine whether fatigue develops with 100 Hz tetanic stimulation in anaesthetized, non-relaxed patients with normal or abnormal baseline electroneurographic (ENG) findings.

Outcome Measures

Primary Outcomes (1)

  • 100 Hz tetanic fade response of abductor digiti minimi muscle to ulnar nerve stimulation in patients with normal and abnormal ENG

    Electroneurography response of the abductor digiti minimi muscle to 100 Hz tetanic stimulation (tetanic fade) is examined to find out if there is difference in patients with or without polyneuropathy. Tetanic fade is the decrease of the twitch heights of the compound muscle action potential due to depletion of cetylcholin stores in the nerve terminal during tetanic stimulation.

    From enrollment until end of anesthesia asessed up to 1 hour. No further ENG measurements are performed in the postoperative period.

Secondary Outcomes (1)

  • Diagnostic feasibility of electromyography in the examination of safety margin

    From enrollment until end of anesthesia assessed up to 1 hour. No further ENG measurements are performed in the postoperative period.

Other Outcomes (1)

  • 60 Hz tetanic fade response of abductor digiti minimi muscle to ulnar nerve stimulation in patients with normal and abnormal ENG

    From enrollment until end of anesthesia assessed up to 1 hour. No further ENG measurements are performed in the postoperative period.

Study Arms (2)

Normal ENG

Patients who have normal results at baseline electroneurogrphy examination

Abnormal ENG

Patients who have abnormal results at baseline electroneurogrphy examination due to polyneuropathy
