The interactions between tubocurarine, pancuronium and alcuronium on neuromuscular transmission have been studied in an isolated neuromuscular preparation (the rat phrenic nerve-hemidiaphragm). Mixtures of tubocurarine and pancuronium, and tubocurarine and alcuronium were found to have a more potent effect than the additive effects of the individual agents when given alone, that is, mixtures we...
Neuromuscular blockade with pancuronium and its antagonism was evaluated in 33 critically ill infants. The evoked contraction of the adductor pollicis from indirect stimulation of the ulnar nerve was measured. The neuromuscular blockade recovered spontaneously from pancuronium in seven infants, 23 required one or more doses of atropine 0.02 ng kg-1 and neostigmine 0.06 mgkg-1. In three infants ...
The effect of pretreatment with suxamethonium, gallamine or pancuronium on suxamethonium-induced fasciculations and myalgia was studied in a controlled, randomized and double-blind clinical trial. Both fasciculations and myalgia were assessed on a four-point rating scale. There was no significant correlation between fasciculations and postoperative muscle pain at 24, 48 or 72 h, and pretreatmen...
Magnesium inhibits the release of acetylcholine from the motor nerve terminal and thus potentiates the action of the non-depolarizing neuromuscular blocking drugs. We have examined the possibility that this effect might enhance the speed of onset of non-depolarizing block with pancuronium. Following the administration of pancuronium 100 micrograms kg-1, 95% depression of thumb twitch occurred i...
BACKGROUND A defasciculating dose of non-depolarizing muscle relaxant administered prior succinylcholine decrease its side effects including fasciculations and postoperative myalgias; however it is believed that the dosage of succinylcholine should be increased when such a pre-treatment is used. OBJECTIVES We hypothesized that a defasciculating dose of pancuronium as a pre-treatment could pro...
Plasma concentrations of pancuronium were measured in nine patients undergoing surgery because of total biliary obstruction. When compared with the averaged model-independent pharmacokinetic parameters obtained for normal patients, the terminal half-life of 270 min was more than twice normal (132 min, P less than 0.001); the plasma clearance of 59 ml min-1 was less than half the normal rate for...
The authors compare the effect of two muscle relaxants, atracurium and pancuronium, on the bradycardia resulting from the oculocardiac reflex during eye surgery for strabismus in children. Two groups, each composed of 15 children, received either pancuronium or atracurium during strabismus operations. Heart rate and rhythm were observed at several points during the operations, and the changes t...
A case of anaphylactic shock to pancuronium bromide is described in which a type I immunological reaction occurred. A 33-yr-old male anaesthetist, with no family or personal history of allergy, collapsed soon after induction of anaesthesia. The drugs used included fentanyl, droperidol, thiopentone and pancuronium. Diffuse erythema occurred, with probable cardiac arrest. The patient was treated ...
The potencies of atracurium, Org NC 45 and pancuronium were determined using cumulative dose-response curves. The effective doses producing 95% twitch depression were 279 microgram kg-1, 56 microgram kg-1 and 64 microgram kg-1 respectively, the relative potency being 1:5.0:4.3. The calculated log-probit dose-response curves showed the steepest slope for pancuronium, although the slopes did not ...
Pancuronium, Org 6368 and gallamine were compared in control cats and in cats with experimental cholestasis. A decrease in the plasma clearance and a prolongation of neuromuscular blockade with Org 6368 and pancuronium were found in the latter; no significant difference was detected in the biotransformation pattern of Org 6368 and pancuronium compared with controls. Inhibition of hepatic uptake...
