Time From Start of Administration of Investigational Medicinal Product (IMP, Sugammadex or Placebo) to Recovery of the Fourth Twitch/First Twitch (T4/T1) Ratio to 0.9 [ Time Frame: From Start of IMP Administration to Recovery of the T4/T1 Ratio to 0.9 (estimated from ~2 minutes up to ~90 minutes) ]
Neuromuscular functioning was monitored by applying repetitive Train-Of-Four (TOF) electrical stimulations to the ulnar nerve every 15 seconds & assessing twitch response at the adductor pollicis muscle. T1 and T4 refer to the magnitudes (height) of the first and fourth twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (a percentage that is expressed as a decimal of up to 1.0) indicates the extent of recovery from neuromuscular blockade (NMB), with a higher ratio indicating a greater recovery from NMB. In this study, twitch responses were recorded until the T4/T1 Ratio reached >=0.9, the minimum acceptable ratio that indicated complete recovery from NMB. A shorter time to recovery of the T4/T1 Ratio >=0.9 indicates a faster recovery from NMB.
Time from start of administration of IMP to recovery of the T4/T1 ratio to 0.9 [ Time Frame: During anesthesia ]

Comparing 4.0 mg.Kg-1 Sugammadex With Placebo in the Reversal of Profound Neuromuscular Blockade (P05767)
A Randomized, Safety-assessor Blinded Trial Comparing 4.0 mg.Kg-1 Sugammadex With Placebo in Adult Subjects Scheduled for Surgery Requiring Profound Neuromuscular Blockade
The current trial was designed to demonstrate faster recovery in participants undergoing elective surgeries requiring profound neuromuscular blockade induced by rocuronium to a fourth twitch/first twitch (T4/T1) ratio of 0.9, after reversal of a target depth of neuromuscular blockade (NMB) of 1-2 Post Tetanic Count (PTC) by 4.0 mg.kg-1 Sugammadex compared to Placebo, to evaluate the safety of 4.0 mg.kg-1 Sugammadex and to evaluate the Operating Room (OR) and Post Anesthetic Care Unit (PACU) length of stay for these participants.

    • Bridion®
  • Drug: 0.9% sodium chloride (NaCl)
    At a target depth of NMB of 1-2 PTC after the last dose of rocuronium, a bolus dose of placebo (0.9% NaCl, volume based on the actual body weight of the participant) will be administered, within 10 seconds into a fast running venous infusion.
    Other Name: Placebo
  • Experimental: sugammadex
    Participants receiving 4.0 mg.kg-1 Sugammadex at a target depth of NMB of 1-2 PTC after the last dose of rocuronium
    Intervention: Drug: Sugammadex
  • Placebo Comparator: Placebo
