In surgical patients, sugammadex produces dose-dependent reversal of NMB induced by rocuronium or vecuronium.20-22 In comparative studies, sugammadex has demonstrated effectiveness superior to cholinesterase inhibitors for NMB reversal at several time points after the administration of rocuronium or vecuronium. This includes routine reversal of deep or moderate NMB and immediate reversal of NMB.23-25 For example, in the routine reversal of deep NMB, sugammadex was associated with a 15-fold shorter median time to recovery of the T4/T1 ratio to 0.9 compared with neostigmine under sevoflurane anesthesia.
