introduction: cataract is an opacified lens and senile cataract is a common disorder. it is desirable to reduce intraocular pressure (iop) in order to minimize intra and post operative difficulties and complications. many researches have studied the effects of muscle relaxants on iop. comparison effect of atracurium and pancuronium on iop has been evaluated in one study with a small sample size...

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...

In the title racemic salt, C(6)H(13)N(2)O(+)·C(8)H(11)O(4) (-), formed from the reaction of cis-cyclo-hexane-1,2-dicarb-oxy-lic anhydride with isonipecotamide, the cations are linked into duplex chain substructures through both centrosymmetric cyclic head-to-head 'amide motif' hydrogen-bonding associations [graph set R(2) (2)(8)] and 'side-by-side' R(2) (2)(14) associations. The anions are inco...

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...

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...

The case of Brase v Rees was presented before the US Supreme Court to consider the constitutionality of death by lethal injection as practiced in the state of Kentucky. The 3-drug combination of sodium thiopental, pancuronium bromide, and potassium chloride is a key aspect in question. Capital punishment conflicts with medical and nursing code of ethics preventing providers who are skilled at d...

The haemodynamic effects of 200 micrograms.kg-1 pipecuronium and pancuronium were compared under etomidate/piritramide anaesthesia in 20 patients scheduled for elective coronary artery surgery. Following the completion of the haemodynamic measurements (ten minutes), anaesthesia was maintained by etomidate/sufentanil infusion. The mean changes in cardiac output were approximately -19 and -2 per ...
