We Japanese anesthesiologists can now use rocuronium as well as vecuronium. Although the onset of rocuronium is more rapid, the non-depolarizing neuromuscular blocking (NMB) agent has similar characteristics of duration and recovery compared to vecuronium. Reversal of NMB is therefore essential to recover patients safely. ⋯ Sugammadex is a novel and unique compound designed as an antagonist of rocuronium and possibly other steroid NMB agents. Sugammadex exerts its effect by forming very tight water-soluble complexes at a 1 : 1 ratio with steroid NMB agents (rocuronium>vecuronium>pancuronium). PhaseIII trials in Japan as well as Europe and the US have just been finished, and it is expected to be used clinically in the near future.

Neuromuscular blocking agents are used to facilitate tracheal intubation and surgical procedure in ambulatory anesthesia. However, the ideal neuromuscular blocking agents for ambulatory anesthesia are not yet available. The only depolarizing neuromuscular blocking agent, suxamethonium, is still widely used by its rapid onset and short duration of action producing excellent intubating conditions, in spite of its numerous adverse effects. ⋯ The use of neostigmine for reversal and the measurement of the TOF ratio during recovery are recommended after intermediate-acting neuromuscular blocking agents. Some studies have shown that tracheal intubation without neuromuscular agents may be associated with postoperative hoarseness and vocal cord injuries. Sugammadex will resolve many issues in using nondepolarizing neuromuscular agents in ambulatory anesthesia.
