Liver function tests following anaesthesia.

Liver function tests were performed in 41 patients who required repeated anaesthetics for genito-urinary surgery, and who had received multiple halothane anaesthetics in the past, first following anaesthesia using halothane and then following an anaesthetic without halothane. There was a smaller frequency of disturbance of liver function after halothane than after the non-halothane anaesthetic. There was no obvious relationship between the number of anaesthetics, or the total duration of anaesthesia, and the disturbance of liver function tests.
