Abstract
OBJECTIVES
Recent reports have shown that intraoperative infusions of glucose and amino acids exert anticatabolic effects. The appropriate dosages of these amino acids and glucose during general anesthesia remain unknown.
METHODS
Patients who underwent esophagectomy for thoracic esophageal cancer were infused with acetated Ringer's solution that contained glucose and amino acids (B1 group [10 patients]: glucose, 3 g/h; amino acids, 1.2 g/h; B2 group [12 patients]: glucose, 4.5 g/h; amino acids, 1.8 g/h) or did not contain glucose and amino acids (C group, 10 patients). The measured energy expenditure was measured by indirect calorimetry. Nitrogen balance was measured during the anesthesia, and the lengths of the hospital stay were recorded.
RESULTS
Resting energy expenditure (B1: 1230 ± 228; B2: 1317 ± 282; C: 1012 ± 153 kcal/h; B2 vs C, P < 0.05) and nitrogen balance (B1: -1.78 ± 0.78 g; B2: -0.85 ± 0.98 g; C: -2.94 ± 2.4 g; B2 vs C, P < 0.05) differed significantly between the B2 and C groups. The lengths of the hospital stay differed between the B2 and C groups (B1: 29 ± 15 d; B2: 18 ± 6 d; C: 37 ± 27 d; B2 vs C, P = 0.06).
CONCLUSIONS
The administration of amino acids and glucose increased measured energy expenditure, alleviated nitrogen balance, and may decrease the length of the hospital stay.
