Abstract

Volatile anaesthetic agents potentiate neuromuscular blocking agents and retard their rate of reversal. We hypothesised that there was a difference in the rate of reversal of rocuronium-induced neuromuscular blockade based on the selection of inhalation agent. Thirty-eight patients undergoing elective surgical procedures received either sevoflurane or isoflurane, by random allocation. Neuromuscular blockade was induced using rocuronium 0.6 mg/kg-1 followed by continuous intravenous infusion to maintain 90% suppression of the single twitch response. Upon completion of surgery, the rocuronium infusion was discontinued, neostigmine 50 μg/kg-1 and glycopyrrolate 10 μg/kg-1 were administered. Times from reversal to T1 = 25, 50 and 60% and train-of-four ratio = 0.6 were recorded. The mean (SD) times to train-of-four ratio = 0.6 in the isoflurane and sevoflurane groups were 327 (132) and 351 (127) s, respectively. The mean (SD) times to single twitch response T1 = 25, 50 and 60% in the isoflurane group were 81 (33), 161 (59) and 245 (84) s, respectively, and in the sevoflurance group were 95 (35), 203 (88) and 252 (127) s, respectively. It is concluded that reversal of rocuronium-induced neuromuscular blockade is similar during isoflurane and sevoflurane anaesthesia.
