Effects on hemodynamics and blood catecholamine levels of pancuronium and vecuronium used during the induction of anesthesia, were studied in patients undergoing coronary artery bypass grafting. Anesthesia was induced out with fentanyl, 70 micrograms.kg-1, and diazepam, 0.2 mg.kg-1, and either pancuronium or vecuronium was administered in a dose of 0.2 mg.kg-1. Control measurements were made before the induction of anesthesia. Hemodynamic parameters and blood levels of norepinephrine (NEP) and epinephrine (EP) were measured three minutes (S1) and ten minutes (S2) after tracheal intubation. The study showed that HR, AP, CI, and coronary perfusing pressure were more stable in the group of patients receiving pancuronium (group P) than in the group receiving vecuronium (group V) during the induction of anesthesia. LVSWI and RVSWI showed a comparable decline in both groups. While NEP was unaffected in group P during the induction of anesthesia, it decreased significantly at S1 and S2, compared with control (S0), in group V. On the other hand, EP decreased significantly at S1 and S2 during the induction of anesthesia in both groups, but group V showed a greater change. The results of this study suggest that pancuronium is more advantageous than vecuronium as a muscle relaxant used during the induction of high-dose fentanyl anesthesia.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009125	Muscle Relaxants, Central	A heterogeneous group of drugs used to produce muscle relaxation, excepting the neuromuscular blocking agents. They have their primary clinical and therapeutic uses in the treatment of muscle spasm and immobility associated with strains, sprains, and injuries of the back and, to a lesser degree, injuries to the neck. They have been used also for the treatment of a variety of clinical conditions that have in common only the presence of skeletal muscle hyperactivity, for example, the muscle spasms that can occur in MULTIPLE SCLEROSIS.

D010197	Pancuronium	A bis-quaternary steroid that is a competitive nicotinic antagonist. As a neuromuscular blocking agent it is more potent than CURARE but has less effect on the circulatory system and on histamine release.

D002395	Catecholamines	A general class of ortho-dihydroxyphenylalkylamines derived from TYROSINE.	Catecholamine,Sympathin,Sympathins
D005283	Fentanyl	A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance.

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.
