The study was undertaken to determine whether a neuromuscular blockade induced with pancuronium but maintained with atracurium was associated with a shorter time to complete recovery after administration of neostigmine than if the blockade was maintained with pancuronium alone. Anaesthesia consisted of thiopentone, N2O/O2/enflurane and fentanyl, and the neuromuscular blockade, induced by pancur...

Dose-duration relationships for vecuronium were determined and the duration of action produced by vecuronium 0.3 mg kg-1 shown to equal that of pancuronium 0.1 mg kg-1. Using these doses, the neuromuscular blocking properties and cardiovascular effects of the two drugs were compared. With large dose administration of vecuronium (0.3 mg kg-1), both the onset time (mean 81 s) and the 25-75% recov...

The effects of atracurium on intraocular pressure (IOP) were compared with those of pancuronium in 20 patients less than 45 years-of-age requiring surgery for trauma of one eye. After a standard premedication and the application of topical analgesia to the upper airway, anaesthesia was induced with thiopentone i.v. and the trachea was intubated without the use of neuromuscular blockade. Followi...

The effect of atracurium on intraocular pressure was studied by comparing it with pancuronium in a randomised controlled trial. The intraocular pressure was measured in patients undergoing cataract surgery before administration of the muscle relaxant, at 1, 3, and 5 minutes after its administration, and at 1 minute after tracheal intubation. Atracurium was found to decrease intraocular pressure...

There are a number of factors to consider in choosing a muscle relaxant for patients with a phaeochromocytoma. It has been suggested that pancuronium is the muscle relaxant of choice, i-3 This report describes a severe hypertensive response associated with pancuronium in a patient undergoing surgery for the removal ofa phaeochromocytoma.

Cumulative dose-response curves were constructed to determine the comparative potency of pipecuronium and pancuronium. From these, the ED50 and ED95 values were calculated. These were 24.96 micrograms kg-1 and 44.96 micrograms kg-1, respectively, for pipecuronium and 30.42 micrograms kg-1 and 61.12 micrograms kg-1, respectively, for pancuronium.

Intubating conditions were studied in two groups of patients who received either fazadinium 1 mg/kg or pancuronium 0.1 mg/kg (group 1), or either fazadinium 0.5 mg/kg or pancuronium 0.08 mg/kg (group 2). In group 1 intubating conditions were studied at 30, 45, 60 and 75 s after injection of the relaxant drug, and in group 2 at 60 s after injection. Fazadinium provided better intubating conditio...

We report three infants paralysed with pancuronium bromide as an adjunct to mechanical ventilation, who developed multiple joint contractures. In two term infants, gentamicin and phenobarbitone given together with pancuronium may have potentiated its effect, and in one preterm infant contractures, which became more severe after paralysis, were present at birth.
