The cardiovascular effects of sevoflurane are similar to those of isofluran
e with some minor exceptions. In contrast to isoflurane and particularly to
desflurane, sevoflurane has not been associated with increases in heart ra
te in healthy volunteers and in patients. The coronary vasodilatory potency
of sevoflurane appears to be lower than that of isoflurane and it has not
been associated with a reduction of blood flow to collateral myocardium in
dogs with steal-prone anatomy. In several multi-center studies of patients
with coronary artery disease or at high risk for coronary artery disease re
ceiving either sevoflurane or isoflurane far either cardiac or non-cardiac
surgery, the incidence of myocardial ischemia and infarction did not differ
between treatment groups. In both human and animal models,sevoflurane pres
erves cerebral blood flow and reduces cerebral metabolic rate, much like is
oflurane.
