Abstract

Previous studies have demonstrated that oxidative stress by mediating the excessive production of reactive oxygen species is involved in tissue damage and organ failure during and after surgery. The impact of the preoperative immunonutrition including antioxidants on the postoperative course of patients undergoing hepatic surgery was investigated in this pilot study. Twenty-three living donor liver transplantation (LDLT) donors were randomly assigned to either an experimental (AO) group, received a commercial supplement enriched with antioxidant nutrients for each of the 5 days immediately prior to surgery while maintaining normal food intake, or a control (CT) group, administered no supplement. Antioxidative capacity was measured by spectrophotometry of patient serum using a free-radical analytical system. The antioxidative capacity of 90.9% patients in the AO group increased after immunonutrition. Compared to the CT group, the AO group was found to have higher antioxidant capacity and transferrin levels; lower WBC, lymphocyte, and neutrophil counts; and briefer duration of postoperative fever during the postsurgical period. No significant differences were found between the 2 groups regarding the nutritional parameters; liver functioning parameters; immunological parameters; intraoperative factors; postoperative outcomes. Preoperative immunonutrition including antioxidants might play a beneficial role in improving postsurgical immunological response but the modest biological advantage was not associated with any significant clinical outcome.
