Reversal of pipecuronium bromide with pyridostigmine.
Pipecuronium Bromide (Arduan, Organon, Inc, West Orange) is a long-acting, nondepolarizing neuromuscular blocking agent. The efficacy of pyridostigmine 170 micrograms/kg intravenously (approximately 10 mg/70 kg) for reversing pipecuronium has not been reported. This study was performed to determine the time required to obtain a train-of-four (TOF) ratio of 0.7 after administration of pyridostigmine 140 micrograms/kg at 25% recovery of T1 after pipecuronium-induced neuromuscular blockade. Sixteen, American Society of Anesthesiology (ASA) I or II patients undergoing surgical procedures of at least 90 minutes, requiring intubation and muscle relaxation were included. Neuromuscular blockade was assessed using the Puritan-Bennett/Datex NMT 221 placed for ulnar nerve stimulation. Anesthesia was maintained with a nitrous oxide/narcotic technique and the use of potent inhalational anesthetics was avoided. The mean reversal time was found to be 16.14 minutes, with a minimum of 10.3 minutes and a maximum of 24.3 minutes. The standard error was +/- 1.05 minutes with a variance of 17.68 minutes.
