Abstract

The postoperative changes in serum aspartate aminotransferase (SGOT), serum alanine aminotransferase (SGPT), and lactate dehydrogenase (LDH) levels after major lung operations were studied in patients some of whom received halothane and some of whom did not. There were no differences between the two groups of cases. It seemed possible that the rises in SGOT and LDH which occurred quite frequently were an indication that tissue autolysis was occurring in the body.
