BackgroundEfficacy and safety of sugammadex in reversing neuromuscular block induced by rocuronium or vecuronium were investgated in Japanese patients.MethodsWe studied 98 Japanese patients undergoing surgery requiring general anesthesia. Patients were allocated randomly to receive intubation dose of rocuronium or vecuronium. During surgery, patients received additional doses of rocuronium or vecuronium for maintenance of moderate block. At T2 reappearance sugammadex 0-4.0 mg . kg-1 was administered. The neuromuscular block was monitored with acceleromyography using TOF stimuli. Sevoflurane was administered to all treatment groups after intubation.ResultsFor the rocuronium-induced neuromuscular block, the mean recovery time of the T4/T1 ratio to 0.9 decreased from 82.1 min in the placebo group to 1.8 min in the 4.0 mg . kg-1 sugammadex group. For the vecuronium-induced neuromuscular block, it decreased from 83.2 min in the placebo group to 2.1 min in the sugammadex 4.0 mg . kg-1 group. Plasma concentrations of sugammadex were approximately dose proportional over the dose range of 0.5 to 4.0 mg . kg-1 and independent of the neuromuscular blocking agents used. No clinical evidence of recurarization or residual curarization was observed.ConclusionsThe efficacy and safety of sugammadex were confirmed in Japanese surgical patients.
