Halogenated inhalational anesthetics have been implicated in hepatotoxicity. Halothane hepatitis results from the biotransformation of the drug to a metabolite that binds to liver proteins, which creates a hapten, which, in turn, causes an immunologic response in the liver. Case reports of hepatic injury resulting from isoflurane, which has a decreased biotransformation compared with that of halothane, have received much criticism. We describe a patient who had elevated liver enzymes and a positive trifluoroacetyl antibody titer following an anesthetic regimen that included isoflurane.
