Electrophysiological Comparison of mAP and mADM Using EMG

Electrophysiological Comparison of mAP and mADM Using EMG

The primary aim of this clinical investigation is to examine a prototype of a quantitative monitoring instrument that will meet most, if not all, of the clinical requirements.

This is a blinded, single-center, prospective study in patients during surgery, requiring use of neuromuscular blockade. Neurostimulation will be used to monitor objective responses, as per current clinical routine. Data collection of Tetragraph EMG responses will be unavailable to the clinician for clinical decision-making, as per current clinical routine, but will be stored on the interfaced SD card.
