简要总结
This study administers sugammadex sodium to pediatric patients under general anesthesia with rocuronium. Pharmacokinetic and pharmacodynamic analysis are performed based on plasma concentration of sugammadex sodium and monitoring of neuromuscular blockade.
详细描述
This study enrolls pediatric patients undergoing surgery under general anesthesia with need for reversal of neuromuscular blockade, aged between 2 and 18 years old.
After routine anesthetic induction with 1% propofol and 0.6mg/kg of rocuronium, maintenance of anesthesia with total intravenous anesthesia is commenced. For neuromuscular monitoring, train-of-four (TOF) count and T4/T1 ratio are monitored, with recording of the time to recovery of the T4/T1 ratio to 0.7, 0.8 and 0.9.
On reappearance of T2 after rocuronium administration , 2 or 4 or 8mg/kg of sugammadex sodium or conventional neuromuscular reversal agent is administered according to randomization table.
For pharmacokinetic analysis, patient blood sample is obtained before / 2 min after rocuronium administration, before / 2min / 5min / 15min / 60min / 120min / 240min / 480min after sugammadex administration. Plasma concentration of rocuronium and sugammadex sodium are analyzed via high-performance liquid chromatography with mass spectrometric detection.
