Sugammadex, a modified γ-cyclodextrin is a selective relaxant-binding agent that reverses the effects of steroidal neuromuscular blocking agents, rocuronium and vecuronium. It shows its activity by encapsulating these. Likewise, some other steroid hormones and drugs like flucloxacillin, toremifene, fusidic acid can also be effected. Thus, assuming that methylprednisolone would also be encapsulated by sugammadex and decrease its efficiency, in this study we aimed to compare the recovery times from recuronium-induced muscle relaxation after reversal with sugammadex between patients who receive intraoperative methylprednisolone or not.
