Retrospective study of post-anesthetic mild liver disorder associated with inhalation anesthetics, halothane and enflurane.
The incidence of post-anesthetic mild liver disorder (PAMLD) was compared between 928 patients administered halothane and 1766 patients administered enflurane. They were selected from 19 504 surgical patients administered general anesthesia at Kyushu University Hospital over the past 6 years and 4 months. They had had normal liver function before operation and had no history of blood transfusion. Alanine aminotransferase (ALT) levels exceeding 70 IU. l(-1) within 180 days after operation were found in 226 patients in the halothane group (24.4%), and in 250 patients in the enflurane group (14.2%) ( P < 0.01). Both maximum ALT levels and duration of ALT elevation were higher and longer in the halothane group ( P < 0.01). These results suggest that, not only in the development of fulminant hepatitis but also in PAMLD, enflurane is less hepatotoxic than halothane.
