“…Sevoflurane undergoes dose-dependent, limited hepatic biotransformation, principally by cytochrome P450 2E1, as evidenced by increases in organic and inorganic fluoride levels (18,19). Some drugs, such as acetaminophen, used for anesthesia and/or analgesia, may participate in hepatic failure following anesthesia with sevoflurane (20,21). Thiopental may induce cytochrome P450, which in a glutathionedepleted patient leads to a increased acetaminophen metabolite, which is hepatotoxic (22).…”
