Official Title: A Multi-center, Open Label Trial, to Show Efficacy and Safety of 4.0 mg.Kg-1 Sugammadex Administered at a Depth of Neuromuscular Blockade of 1-2 PTC Induced by Rocuronium in Chinese and European ASA I-III Subjects Undergoing Elective Surgery Under Propofol Anesthesia

Primary Outcome Measures:
  • Time From Start of Administration of Sugammadex to Recovery of the T4/T1 Ratio to 0.9 [ Time Frame: Start of administration of sugammadex to recovery from neuromuscular blockade ] [ Designated as safety issue: No ]

    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. Nerve stimulation continued until the ratio of the magnitude of the fourth twitch (T4) to first twitch (T1) reached at least 0.9. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade, with a value of 1.0 representing full recovery.

    Analysis of recovery in Chinese subjects was the primary objective; Caucasian subjects and between-group analyses were secondary.



Secondary Outcome Measures:
  • Time From Start of Administration of Sugammadex to Recovery of the T4/T1 Ratio to 0.7 [ Time Frame: Start of administration of sugammadex to recovery from neuromuscular blockade ] [ Designated as safety issue: No ]
    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. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade.

  • Time From Start of Administration of Sugammadex to Recovery of the T4/T1 Ratio to 0.8 [ Time Frame: Start of administration of sugammadex to recovery from neuromuscular blockade ] [ Designated as safety issue: No ]
    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. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade.

Arms Assigned Interventions
Experimental: Sugammadex in Caucasian Subjects
At 1-2 post-tetanic counts (PTC) after the last dose of rocuronium, 4.0 mg.kg-1 sugammadex was to be administered. Caucasian subjects living in Europe.
Drug: Sugammadex
After induction of anesthesia an intubation dose of 0.6 mg/kg rocuronium was to be administered. Maintenance doses of 0.1-0.2 mg/kg rocuronium intravenous (IV) could have been administered if necessary. At 1-2 PTC after the last administration of rocuronium, an IV single bolus dose of 4.0 mg/kg sugammadex was to be administered.

Experimental: Sugammadex in Chinese Subjects
At 1-2 post-tetanic counts (PTC) after the last dose of rocuronium, 4.0 mg.kg-1 sugammadex was to be administered. Chinese subjects living in China.
Drug: Sugammadex
After induction of anesthesia an intubation dose of 0.6 mg/kg rocuronium was to be administered. Maintenance doses of 0.1-0.2 mg/kg rocuronium intravenous (IV) could have been administered if necessary. At 1-2 PTC after the last administration of rocuronium, an IV single bolus dose of 4.0 mg/kg sugammadex was to be administered.

Criteria

Inclusion Criteria:

-Subjects who are willing to provide informed consent; be between 18 and 64 years old; are American Society of Anaesthesiology (ASA) class 1-3 (extremes included); scheduled for elective surgery under general anesthesia, allowing stable neuromuscular monitoring, which requires neuromuscular blockade using

rocuronium; be compliant with the dose/visit schedules, and use an accepted method of contraception (if applicable).

For China only: Subjects of Chinese descent born in China, never emigrated out of China and have a Chinese home address. For Europe only: Subjects of Caucasian descent born in Europe, never emigrated out of Europe and have a European home address.

Exclusion Criteria:

-Subjects with expected difficult intubation, neuromuscular disorders affecting neuromuscular blockade, significant renal/hepatic dysfunction, use of a tourniquet, (family) history of malignant hyperthermia, allergy to general anesthesia medications, contraindication to study drugs, breast feeding, pregnant, participation in previous or new trials, a clinically significant condition that may interfere with the trial, or membership in the

(family of) study/sponsor staff.
