Sevoflurane or Isoflurane Which One to Use and Why
This is considerably lower than the MAC of sevoflurane at approximately 2.4 in both species When you consider that surgical anaesthesia is normally achieved at 1.5 times MAC it becomes clear that a considerably higher vaporiser setting will be required when using sevoflurane compared to if the same patient were anaesthetised using isoflurane.

Anesthesia Induced Oxidative Stress Are There Differences
Sevoflurane appears to induce the least cerebral vasodilation among the modern agents and in fact it has been shown that at 1 MAC minimum alveolar concentration cerebral autoregulation and CO 2 reactivity are preserved thus making sevoflurane the preferred volatile agent for neurosurgical patients with increased intracranial pressure 20
