Intubation conditions and time-course of action of low-dose rocuronium bromide in day-case dental surgery.

A relatively small dose of rocuronium (0.45 mg kg-1) was compared with equipotent doses of atracurium (0.35 mg kg-1) and vecuronium (0.075 mg kg-1) for ease of intubation at 60 s. All patients could be intubated but the proportion with excellent or good conditions was much greater with rocuronium. Mean clinical duration of effect of this dose was 22.2 min. There was no correlation between intubating conditions and the degree of block of the adductor policis.
