A multi-center, randomized, parallel-group, safety assessor-blinded trial comparing efficacy and safety of 4.0 mg.kg-1 Org 25969, administered at T1 3-10% after continuous infusion of rocuronium, and pharmacokinetics of rocuronium, between subjects receiving maintenance anesthesia using propofol and subjects receiving maintenance anesthesia using sevoflurane.

Primary

MeasureTime frame
Main Objective: To show equivalence in recovery from neuromuscular block after a single dose of 4.0 mg.kg-1 Org 25969, administered at T1 3-10% after continuous infusion of rocuronium, between subjects receiving maintenance anesthesia using propofol and subjects receiving sevoflurane.;Secondary Objective: • To investigate the safety of a single dose of 4.0 mg.kg-1 Org 25969, administered at T1 3-10% after continuous infusion of rocuronium, under either propofol or sevoflurane anesthesia. • To compare the plasma levels of rocuronium in subjects after continuous infusion of rocuronium and before the administration of Org 25969, under either propofol or sevoflurane anesthesia. ;Primary end point(s): Time from start administration of Org 25969 to recovery T4/T1 ratio to 0.9.
