Neuromuscular Blockade
Conditions
Brief summary
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.
Interventions
The variation between arms (dominant or non-dominant) when monitored with the same method on both arms
