入选标准
- •Participants of American Society of Anesthesiologists (ASA) class 1 - 3;
- •Participants at least 20 years but under 65 years of age;
- •Japanese participants;
- •Participants scheduled for elective surgery in supine position and under sevoflurane anesthesia, in need of administration of a neuromuscular blocking agent (NMBA), with an anticipated duration of about 1.5-3 hours;
- •Participants who had given written informed consent. This was obtained before the investigator or the sub-investigator performed any procedures or assessments for the screening, and after the participant was informed about the nature and purpose of the study, the study procedures, and the risks and restrictions of the study.
排除标准
- •Participants in whom a difficult intubation because of anatomical malformations was expected;
- •Participants known or suspected to have neuromuscular disorders impairing neuromuscular blockade (NMB) and/or significant renal dysfunction (for example a creatinine level > 1.6 mg/dl) and/or severe hepatic dysfunction.
- •Participants known or suspected to have a (family) history of malignant hyperthermia;
- •Participants known or suspected to have an allergy to narcotics, muscle relaxants or other medication used during general anesthesia;
- •Participants receiving medication expected to interfere with the rocuronium or vecuronium given in this trial, based on the dose and time of administration;
- •Female participants who were pregnant;
- •Female participants of childbearing potential not using birth control or using only oral contraception as birth control;
- •Participants who were breast-feeding;
- •Participants who had already participated in study CT 19.4.209A, or in another trial with sugammadex;
- •Participants who had participated in another clinical trial within 6 months of entering into study CT 19.4.209A.
研究组 & 干预措施
Sugammadex 0.5 mg/kg (Rocuronium)
After induction of anesthesia an intubation dose of 0.9 mg/kg rocuronium was administered intravenously (IV), followed by maintenance doses of 0.1-0.2 mg/kg rocuronium IV if necessary. At reappearance of the second twitch (T2) response to Train-of-four (TOF) stimulation, a single dose of 0.5 mg/kg sugammadex was administered IV.

结局指标
主要结局
Time From Start of Sugammadex Administration to Recovery of the Neuromuscular Response to a Ratio of 0.9 for Train-Of-Four (TOF) Stimulation
时间窗: Up to 269:45 (min:sec)
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 and T4 refer to the amplitudes (heights) of the first and fourth twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (expressed as a decimal of up to 1.0) indicates the extent of recovery from neuromuscular blockade (NMB). In this study, twitch responses were recorded until the T4/T1 Ratio reached \>= 0.9, the minimum acceptable ratio that indicated recovery from NMB. A faster time to recovery of the T4/T1 Ratio to 0.9 indicates a faster recovery from NMB.
