Summary

Researchers are comparing the ease of use and repeatability of the force vs electrical activity produced by a muscle after it has undergone nerve stimulation during a surgical procedure in which the patients' arm movement is restricted (placed under surgical drapes) in laparoscopic or robotic procedures.

Conditions

• Residual Neuromuscular Blockade

Interventions

Type	Name	Description
DEVICE	Tetragraph	FDA approved neuromuscular transmission monitor capable of measuring the depth of neuromuscular block in anesthetized patients who received neuromuscular blocking agents. TetraGraph uses EMG to measure the muscle action potentials that are generated in response to electrical neurostimulation via skin electrodes.
DEVICE	ToFscan	ToFscan is a nerve stimulator module used for the measurement of neuromuscular transmission via accelerometry. ToFscan was developed by Drager Technologies, Canada, and it uses a three-dimensional piezoelectric sensor that attaches to the thumb via a hand adapter to measure acceleration in multiple planes (Murphy et al, 2018). Following simultaneous ulnar nerve stimulation on each arm, the response of the adductor pollicis will be measured
