Comparaison des effets hémodynamiques du fazadinium, du pancuronium et de l'alcuronium chez l'insuffisant coronaire: Trente observations

Abstract

Cardiovascular effects of neuromuscular blocking agents mainly guide the choice of these relaxants in patients with cardiovascular disease. The purpose of this study was to compare the hemodynamic effects of fazadinium (1 mg · kg −1), pancuronium (0,08 mg · kg −1) and alcuronium (0,2 mg · kg −1) in 30 coronary patients without beta-blocking therapy. No hemodynamic changes were observed after pancuronium. Fazadinium induced at the fifth minute a mean five p. 100 decrease in mean arterial pressure, cardiac index, stroke volume and systemic vascular resistance. At the fifth minute with alcuronium, mean arterial pressure decreased (22 p. 100) (p <0.01) with a decrease in cardiac index (12 p. 100), stroke volume (8 p. 100) and systemic vascular resistance (10 p. 100). This study shows that pancuronium and fazadinium are well tolerated. Alcuronium induces at the fifth minute a significant decrease in arterial pressure. This effect does not seem to be deleterious in normovolemic patient with coronary artery disease without beta-blocking therapy.
