Overview

Brief Summary

The purpose of the trial is to demonstrate a faster recovery from neuromuscular block induced by 1.2 mg/kg rocuronium after reversal at 3 minutes by 16.0 mg/kg of sugammadex compared with recovery after a neuromuscular block induced by 1.0 mg/kg succinylcholine.

Eligibility Criteria

Inclusion Criteria

  • American Society of Anesthesiologists (ASA) Class 1 or 2 physical status;
  • 18 to 65 years of age (inclusive);
  • Scheduled for elective surgical procedure under general anesthesia requiring a short duration of neuromuscular block with the use of rocuronium or succinylcholine and requiring endotracheal intubation;
  • Scheduled for surgery in supine position;
  • Body mass index (BMI) \< 30;
  • Given written informed consent.

Exclusion Criteria

  • Has ischemic heart disease or history of myocardial infarction within the last year;
  • May experience difficult intubation due to anatomical malformations;
  • Known or suspected to have neuromuscular disorders impairing neuromuscular blockade and/or significant renal dysfunction;
  • Known or suspected family history of malignant hyperthermia;
  • Known or suspected allergy to narcotics, muscle relaxants, midazolam, anesthetics or other medications used during surgery;
  • Is receiving medication known to interfere with neuromuscular blocking agents such as anticonvulsants, antibiotics and Mg2+;
  • Individuals in whom the use of neostigmine and/or glycopyrrolate may be contraindicated;
  • Females who are pregnant or breast-feeding;
  • Females of childbearing potential who are not using an acceptable method of birth control \[condom or diaphragm with spermicide, vasectomized partner (\> 6 months), IUD, abstinence\];
  • Has already participated in a sugammadex trial including Protocol 19.4.303.

Arms & Interventions

Rocuronium + Sugammadex

Participants were to receive a single bolus dose of 1.2 mg/kg rocuronium. Three minutes after the start of the rocuronium administration, they were to receive a single bolus dose of 16.0 mg/kg sugammadex.

Intervention: Sugammadex

Rocuronium + Sugammadex

Participants were to receive a single bolus dose of 1.2 mg/kg rocuronium. Three minutes after the start of the rocuronium administration, they were to receive a single bolus dose of 16.0 mg/kg sugammadex.

Intervention: Rocuronium

Succinylcholine

Participants were to receive a single bolus dose of 1.0 mg/kg succinylcholine and allowed to recovery spontaneously from neuromuscular blockade.

Intervention: Succinylcholine

Outcomes

Primary Outcomes

Time to Recovery of T1 to 10% of Baseline Value From Start of Rocuronium + Sugammadex or Succinylcholine Administration

Time Frame: Up to 15 minutes after administration of rocuronium + sugammadex or succinylcholine

Neuromuscular functioning was monitored by applying repetitive Train-Of-Four (TOF) electrical stimulations to the ulnar nerve every 15 seconds and assessing twitch response at the adductor pollicis muscle. T1 refers to the amplitude (height) of the first twitch after TOF nerve stimulation.

Secondary Outcomes

  • Time to Recovery of T1 to 90% of Baseline Value From Start of Rocuronium + Sugammadex or Succinylcholine Administration(Up to 20 minutes after administration of rocuronium + sugammadex or succinylcholine)
  • Number of Participants Experiencing General Muscle Weakness(Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine)
  • Level of Consciousness: Number of Participants Awake and Oriented(Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine)
  • Level of Consciousness: Number of Participants Arousable With Minimal Stimulation(Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine)
  • Level of Consciousness: Number of Participants Responsive Only to Tactile Stimulation(Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine)
  • Number of Participants Able to Perform 5-Second Head Lift(Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine)
