AbstractWe examined the use of neostigmine for reversing shallow (defined as train-of-four ratio of 0.5), cisatracurium- and rocuronium-induced neuromuscular block in 112 patients, by use of 0 μg.kg(-1) , 10 μg.kg(-1) , 20 μg.kg(-1) or 40 μg.kg(-1) dose of neostigmine for reversal. The times from neostigmine administration to train-of-four ratios of 0.7, 0.9 and 1.0 were evaluated. Analysis of variance showed that the duration of action was significantly longer after cisatracurium compared with rocuronium. The time to reach a train-of-four ratio of 1.0 was significantly shorter with neostigmine 40 μg.kg(-1) compared with lower neostigmine doses, and at this dose the time did not differ between cisatracurium and rocuronium. The recovery time from a train-of-four ratio of 0.5-1.0 did not differ between cisatracurium and rocuronium, and was significantly shortened by the administration of neostigmine. We conclude that a neostigmine dose of 40 μg.kg(-1) was the most effective at reducing recovery time after neuromuscular blockade. © 2016 The Association of Anaesthetists of Great Britain and Ireland.
