The effect of acutely administered phenytoin on vecuronium-induced neuromuscular blockade. 1989

Department of Anaesthetics, Manchester Royal Infirmary.

Phenytoin was administered intravenously in a dose of 10 mg kg to a group of patients in whom steady state neuromuscular blockade had been established with an infusion of vecuronium. A control group of patients were given 0.9% saline instead of phenytoin. Administration of phenytoin produced significant augmentation of neuromuscular blockade (p less than 0.001). The possible mechanism of this effect is discussed.

D010672	Phenytoin	An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.

D014673	Vecuronium Bromide	Monoquaternary homolog of PANCURONIUM. A non-depolarizing neuromuscular blocking agent with shorter duration of action than pancuronium. Its lack of significant cardiovascular effects and lack of dependence on good kidney function for elimination as well as its short duration of action and easy reversibility provide advantages over, or alternatives to, other established neuromuscular blocking agents.
