A new NMT module from Mindray (Mindray Co. Shenzhen, People's Republic of China.) claims to
measure 3 directional accelerography. The aim of the study is to compare the neuromuscular
block of rocuronium 0.6 mg/kg (twice the 95% effective dose, ED95) monitored by the NMT
versus that monitored by the Relaxometer Mechanomyograph on the other hand in Group 1, and
versus the TOF-Watch on the other hand in Group 2 to clinically evaluate the new system for
its diagnostic accuracy.
