Halothane, isoflurane and desflurane are metabolized to hepatotoxic trifluoroacetyl proteins. But sevoflurane is metabolized to hexafluoroisopropanol. Hexafluoroisopropanol has a low binding affinity for liver protein and is therefore rapidly converted to glucuronidate that are excreted in the urine. Thus sevoflurane has been considered to have a very low potential for hepatotoxicity. We report a case of a 67 years old woman who developed acute hepatic dysfunction after sevoflurane anesthesia.
