Abstract
In experiments on isolated rat heart lung preparation, the effects of sevoflurane on myocardial metabolism during postischemic reperfusion were evaluated with intramyocardial high energy phosphates, lactate and glycogen. Hearts were perfused for 10 min initially and made globally ischemic for 8 min. Afterwards, they were reperfused for 12 min. Sevoflurane was administered from 5 min after the start of perfusion to the end of reperfusion. There was no significant difference in myocardial lactate levels between the sevoflurane (S) and control groups. However, the myocardial ATP level in Group S was significantly higher than that in control (17.45 +/- 1.51 vs 15.50 +/- 0.87 : P < 0.01). The administration of sevoflurane to the isolated rat heart during pre- and post-ischemia enhanced metabolic recovery in the postischemic state.
