title: [Interaction of midazolam and vecuronium in anesthetized patients].
abstract: The interaction between midazolam and vecuronium was investigated in 60 patients during isoflurane-nitrous oxide-oxygen anesthesia. Neuromuscular function was evaluated by recording the single twitch of the abductor pollicis muscle. Anesthesia was induced with thiamylal 4 mg.kg-1 or midazolam 0.2 mg.kg-1 followed by injection of vecuronium 0.1 mg.kg-1. Observed values after midazolam were compared with those observed in patients with thiamylal. the onset time and the duration of action until 25% recovery were similar with both groups. Midazolam caused no significant potentiation of neuromuscular blocking agents in comparison with the control. Therefore, there was no evidence of any interaction between midazolam and vecuronium during isoflurane-nitrous oxide-oxygen anesthesia.
