Abstract:
Myocardial oxygen supply and demand in the normal dog were evaluated as the concentration of halothane, enflurane or isoflurane was increased. Although coronary blood flow decreased as the anaesthetic gas concentration increased, the O2 supply-to-demand ratio remained stable owing to a decrease in the myocardial O2 consumption.
