The Precision and Arm-to-Arm Variation of Mechanomyography and Acceleromyography for Monitoring of Neuromuscular Block

Rigshospitalet

Status: Completed

Conditions: Neuromuscular Blockade

Treatments: Device: TOF-Watch SX (neuromuscular monitor)

Study type: Observational

About

The purpose of the study is the examine the precision of acceleromyography and mechanomyography during recovery from a neuromuscular blocking agent and to examine whether there is any difference in monitoring block at the dominant or non-dominant arm. Our hypothesis is that there is no significant difference in neither the precision nor the level of block in the contralateral arms.
