Hepatic enzyme response and hyperpyrexia after severe liver injury

A multi-center experience with 210 severe liver injuries was reviewed to define postoperative changes in hepatic enzyme levels and body temperature profile. The 129 patients who survived initial operation comprised the data base. Serum glutamic oxaloacetic transaminase (SGOT) and lactate dehydrogenase (LDH) peaked within 24 hours (750 +/- 92 IU/L, 870 +/- 120 IU/L) and decreased rapidly during the first 4 days. Serum bilirubin was maximal at 7 days, while alkaline phosphatase rose slowly throughout 14 days. Hepatic enzyme elevations were more dramatic after blunt trauma, reflecting greater hepatocellular disruption. Maximum daily temperatures exceeding 38.0 degrees C and 39.0 degrees C were recorded for the first 3 postoperative days in 82 (64%) patients and 14 (11%) patients, respectively. No infectious source was evident in 13 (93%) of 14 patients with severe hyperpyrexia, implicating release of inflammatory mediators associated with major hepatic trauma. Convalescence from severe hepatic injury is marked by release of SGOT and LDH, as well as fever, which may be anticipated during the first 4 days postinjury.
