It is known that volatile anaesthetics protect myocardial tissue against ischaemic and reperfusion injury in vitro. In this investigation, we have determined the effects of the inhalation anaesthetics, enflurane, isoflurane, sevoflurane and desflurane, administered only during early reperfusion, on myocardial reperfusion injury in vivo. Fifty chloralose-anaesthetized rabbits were subjected to 30 min of occlusion of a major coronary artery followed by 120 min of reperfusion. ⋯ The results show that desflurane and sevoflurane markedly reduced infarct size and therefore can protect myocardium against reperfusion injury in vivo. Enflurane had only a marginal effect and isoflurane offered no protection against reperfusion injury in vivo. These different effects suggest different protective mechanisms at the cellular level.
