  Purpose

The objective of the trial is to determine the relation within a subject between the time to manual detection of the reappearance of T4 measured using a peripheral nerve stimulator (PNS) and the time to recovery of the T4/T1 ratio to 0.9 measured using a TOF-Watch® SX, of 4.0 mg.kg-1 sugammadex administered at 15 minutes after either a bolus dose of 0.6 mg.kg-1 rocuronium or the last maintenance dose of 0.15 mg.kg-1 rocuronium

Primary Outcome Measures:
  • Time from start administration of 4.0 mg.kg-1 sugammadex to recovery of the T4/T1 ratio to 0.9 (TOF-Watch® SX) [ Time Frame: after surgery ] [ Designated as safety issue: No ]
  • Time from start administration of 4.0 mg.kg-1 sugammadex to reappearance of T4 (Peripheral Nerve Stimulator). [ Time Frame: after surgery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time from start administration of 1.0 mg.kg-1 sugammadex to recovery of the T4/T1 ratio to 0.9 (TOF-Watch® SX) [ Time Frame: after surgery ] [ Designated as safety issue: No ]
  • Time from start administration of 1.0 and 4.0 mg.kg-1 sugammadex to reappearance of T4 (TOF-Watch® SX) [ Time Frame: after surgery ] [ Designated as safety issue: No ]
  • Time from start administration of 1.0 mg.kg-1 sugammadex to reappearance of T4 (Peripheral Nerve Stimulator) [ Time Frame: after surgery ] [ Designated as safety issue: No ]
  • Time from start administration of 1.0 and 4.0 mg.kg-1 sugammadex to recovery of the T4/T1 ratio to 0.7, T4/T1 ratio to 0.8 (TOF-Watch® SX) [ Time Frame: after surgery ] [ Designated as safety issue: No ]

Detailed Description:

So far, the TOF-Watch® SX has been used for neuromuscular monitoring in all clinical trials with sugammadex. In clinical practice however, a PNS is commonly used in many hospitals worldwide. A disadvantage of the use of a PNS is that it is not objective monitoring like the TOF-Watch® SX and that only the number of twitches that are present can be detected with it. In this trial, a correlation between the time to reappearance of T4 using PNS (i.e. Ministim® model MS-IV) and the time to recovery of the T4/T1 ratio to 0.9 using the TOF-Watch® SX will be determined after a dose of 4.0 mg.kg-1 sugammadex administered 15 minutes after the last dose of rocuronium. This correlation enables to provide an advice on when it is safe to extubate a patient after administration of 4.0 mg.kg-1 sugammadex for reversal of neuromuscular block while using a PNS. The time to reappearance of T4 is being assessed by a blinded PNS-assessor. This person will be blinded for the dose of sugammadex used and for the TOF results measured with the TOF-Watch® SX
