Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

Sugammadex

Drug

After induction of anesthesia an intubation dose of 0.6 mg/kg rocuronium was administered. Maintenance doses of 0.1-0.2 mg/kg rocuronium intravenous (IV) could be administered if necessary. At reappearance of T2 after the last administration of rocuronium, an IV single bolus dose of 2.0 mg/kg sugammadex was administered.

Other names: Org 25969, Bridion®

Neostigmine

Drug

After induction of anesthesia an intubation dose of 0.6 mg/kg rocuronium was administered. Maintenance doses of 0.1-0.2 mg/kg rocuronium IV could be administered if necessary. At reappearance of T2 after the last administration of rocuronium, an IV single bolus dose of 50 µg/kg neostigmine (combined with 10-20 μg.kg-1 atropine, in a ratio ranging from 2.5:1 to 5:1) was administered.

Other names: Neostigmine with atropine

Primary outcomes

Time From Start of Administration of Investigational Medicinal Product (IMP) to Recovery of the T4/T1 Ratio to 0.9.

Time frame: start of administration of sugammadex/neostigmine to recovery from neuromuscular blockade

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 was to continue until the ratio of the magnitude of the fourth twitch (T4) to first twitch (T1) reached >= 0.9. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade, with a value of 1.0 representing full recovery.

The primary analysis was the comparison between sugammadex & neostigmine among Chinese subjects; other comparisons were secondary.

Secondary outcomes

Time From Start of Administration of IMP to Recovery of the T4/T1 Ratio to 0.7 and 0.8.

Time frame: start of administration of sugammadex/neostigmine to recovery from neuromuscular blockade

Neuromuscular functioning was monitored by applying repetitive 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.
