Demographic data, duration of anesthesia and surgery for 24 patients scheduled for hysterectomy and 6 volunteers without surgery. Group A = Amino acid infusion but no anesthesia or surgery; Group B = Ringer's solution infusion throughout anesthesia; Group C = Amino acid infusion throughout anesthesia; Group D = Amino acid infusion started 1 h before anesthesia and during 1.5 h of surgery. Values are mean ± SEM.
