Cerebrovascular Carbon Dioxide Reactivity During General Anesthesia: A Comparison Between Sevoflurane and Isoflurane

Abstract

Changes in cerebral blood flow caused by the changes of carbon dioxide tension are greater during the administration of isoflurane anesthesia compared with sevoflurane anesthesia. Attempts to decrease intracranial pressure by decreasing carbon dioxide tension may be more successful during isoflurane than sevoflurane anesthesia administration.
