Abstract:
Objective: To study the effects of halothane and sevoflurane on myocardial function and energy metabolism. Method:The model of Langendorff perfused isolated rat heart was used to investigate the effects of halothane and sevoflurane on HR,LVEDP,LVDP,+dp/dt,-dp/dt and coronary flow(CF)before and after ischemia. and the myocardial ATP content were measured with HPLC before ischemia and 10 min after ischemia and at the end of reperfusion. Result: 1.5 MAC sevoflurane significantly increased CF in normal isolated rat hearts. Both halothane and sevoflurane differently depressed myocardial contratile function,increased normal myocardial energy storage. At 10th min of ischemia the decrease of myocardial ATP content was delayed by halothane and sevoflurane. At the end of reperfusion,the both anesthetics improved the recovery of myocardial function and matebolism,especially sevoflurane. Conclusion: Both anesthetics can protect myocardium from ischemic reperfusion injury through improving post-ischemic myocardial energy recovery.
