Pharmacokinetics and Pharmacodynamics of Sugammadex in Reversal of Vecuronium-induced Neuromuscular Blockade in Anesthesia Obese Patients Undergoing Bariatric Surgery
Pharmacokinetics and Pharmacodynamics of Sugammadex in Reversal of Vecuronium-induced Neuromuscular Blockade in Anesthesia Obese Patients Undergoing Bariatric Surgery
The purpose of this study is to illustrate pharmacokinetics and pharmacodynamics of sugammadex in reversal of vecuronium-induced neuromuscular blockade in anesthesia obese patients undergoing bariatric surgery.
16 obese patients undergoing bariatric surgery were divided into 2 groups according to body mass index (BMI), including obese group (O group, n=8, 25≤BMI≤39.9kg/m²) and morbidly obese group (M group, n=8, BMI≥40kg/m²).
Vecuronium was continuous infusing to maintain moderate neuromuscular blockade during the laparoscopic surgery and stopped infusing after the laparoscopic procedure. A single dose administration of sugammadex (Sug) 2.0mg/kg according to ideal body weight (IBW) was given at the reappearance of the second twitch of the train-of-four (TOF) response.
On one hand, venous blood samples were obtained before administration of Sug and at 2, 3, 5, 10, 15, 20, 30, 60 minutes and 2, 4, 6, 8 hours after administration of Sug to determine plasma concentration of Sug using HPLC-MS. On the other hand, time from start of administration of Sug to recovery of TOF ratio to 0.9 and other clinical indicators were also recorded.
