Abstract

Nineteen elective surgical patients were prospectively studied for the first five postoperative days. Each patient received a nutritional regimen of 30 n.p. Kcal and 2 g amino acids (Aa) kg-1 day-1 and was assigned to one of three groups whose only difference was the content in branched chain aminoacids (BCAA), (LBCAA received 0.18, MBCAA 0.54 and HBCAA 0.66 g BCAA kg-1 day-1). Every day 3-methyl-histidine (3-Me-His) excretion and nitrogen balance (NB) were calculated. No difference in mean NB and 3-Me-His excretion was found between LBCAA and MBCAA groups (+0.007±0.12 vs +0.034±0.09 g N kg-1 day-1 and 3.7±1.7 vs 4.6±2.2 μMol kg-1 day-1). Mean NB was better in HBCAA (+0.106±0.08 g N kg-1 day-1; P-1 day-1; P-1 day-1). During the first three postoperative days 3-Me-His excretion was the same in all groups, but in HBCAA it was significantly lower (2.8±0.7 vs 4.7±2.2 and 8.0±7.5 μMol kg-1 day-1; P
