Comparison of the TOFScan and the WiTOF During Recovery of Neuromuscular Function

Recovery Evaluation of Two Neuromuscular Blockade Monitoring Devices on Abductor Pollicis Muscle, the TOFScan and the Wireless WiTOF

The purpose of this study is to compare two neuromuscular blockade monitors on recovery from an ATRACURIUM intra veinous injection for surgery. The TOFscan, a wired connected monitors and the WiTOF, a wireless connected monitor.

The secondary objective will be to compare the performance of the two monitors on the abductor pollicis muscle with all the curarisation parameters (TOF, PTC, T4/T1R) and to assess interference occuring during the surgery which could limit the usage of a wireless monitor.
