Dogs received an initial dose of rocuronium 0.6 mg\/kg, or cisatracurium 0.15 mg\/kg IV, which produced complete neuromuscular block. Upon return of the first response (T1) of TOF, a third of the initial dose was repeated. The duration of the initial dose and its variability were compared between agents. Duration of subsequent top\u2010up doses was assessed with mixed effect models. Spontaneous (from last return of T1) or neostigmine\u2010enhanced (from administration to complete recovery) recovery times were measured for each agent.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Duration of action of the initial dose was [median (range)] 25 (10\u201360) min with rocuronium and 35 (15\u201345) min with cisatracurium (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.231). The variability of rocuronium was 3.25 times larger than cisatracurium (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.034). Duration of top\u2010up doses did not vary for either agent.
