Abstract
We compared the toxicities of subanaesthetic concentrations of fluroxene, enflurane and nitrous oxide in mice, rats and guinea pigs which were in an active growth phase. Fluroxene produced a greater mortality and decrement in weight gain than enflurane and nitrous oxide despite administration of far lower concentrations. Enflurane, 0.1 MAC, resulted in a detrimental effect on weight and early mortality in mice but not in rats or guinea pigs. Nitrous oxide, 0.1 MAC, resulted in only a minor effect on weight gain in guinea pigs and an increased incidence of focal inflammatory liver changes in mice. No consistent injury to any organs other than liver or kidney were found. Nous avons comparé la toxicité de concentrations sub-anesthésiques de Fluroxène, ďEnflurane et de Protoxyde ďAzote chez des souris, des rats et des cobayes en croissance. La mortalité et le ralentissement de la croissance sont plus marqués chez les animaux exposés au Fluroxène que chez ceux exposés à ľEnflurane ou au Protoxyde ďAzote, même si le Fluroxène est administré à de beaucoup plus basses concentrations. A 0.1 MAC, ľEnflurane amène une perte de poids et augmente la mortalité précoce chez la souris, mais non chez le rat et le cobaye. Le Protoxyde ďAzote à 0.1 MAC modifiait peu la courbe de poids du cobaye, mais chez la souris, il augmentait ľincidence de modifications inflammatoires hépatiques. Aucun autre organe que le rein et le foie n’a semblé touché.This publication has 21 references indexed in Scilit:
