Notes:
In a randomised prospective cross-over study, we compared the effects of desflurane and isoflurane on arterial oxygenation, heart rate and mean arterial pressure during one-lung anaesthesia. Thirty patients scheduled for oesophagogastrectomy were randomly assigned to one of two groups. One group of 15 patients received desflurane to an end-tidal concentration of 6% in oxygen from induction until the end of 30 min of open chest one-lung ventilation in the lateral position. This was followed by isoflurane to an end-tidal concentration of 1.1% in oxygen for the next 30 min of one-lung ventilation. The other group of 15 patients received the two anaesthetic agents in the reverse order. We found no significant difference in arterial oxygenation, heart rate or mean arterial pressure between the two inhalational agents. In the subgroup of 10 patients with pulmonary artery catheters, we found no significant differences in mixed venous saturation, derived shunt or cardiac output. We conclude that during one-lung ventilation, the choice between desflurane and isoflurane does not significantly influence arterial oxygenation.
