AbstractInjury and stress are accompanied by a characteristic hormonal response and altered energy utilisation. Hyperglycaemia and negative nitrogen (N) balance are the leading symptoms of the metabolic changes in the post-operative state. In a prospective, randomised study the efficacy and metabolic effects of glucose-xylitol (GX) 35% (1:1) versus glucose (G) 40% were investigated in patients undergoing major surgery. METHOD. Twenty-four patients undergoing abdomino-thoracic oesophageal cancer surgery were treated in a standardised manner. Total parenteral nutrition was administered over 6 days (kg body wt.-1/day): day of surgery 1-1.25 g carbohydrate (CH); 1st postoperative day (POD) 1.5 g CH, 1 g amino acids (AA); 2nd POD 3 g CH, 1.5 g AA, 1.0 g fat; from 3rd POD 3 g CH, 1.5 g AA, 1.5 g fat (CH GX35% (n = 12) or G40% (n = 12), AA Intrafusin 15%, fat Intralipid 20%). Daily and cumulative N balances, blood-G profiles, blood chemistry, and physical parameters were determined. Glucagon and insulin profiles, CH losses, and oxalic acid secretion were measured. RESULTS. Both groups were comparable for age, body mass index, clinical and physical parameters, and blood chemistry. Mean cumulative N balances after 6 days were -12.0 +/- 16.3 g N for GX35% and -5.6 +/- 19.4 g N for G40% (n.s.; Wilcoxon, P < 0.05). Blood G was similar for both groups with values ranging from 130 to 240 mg/dl on the day of surgery and below 150 mg/dl on the consecutive days. In each group 1 patient needed additional insulin therapy. Glucagon and insulin levels did not show a significant difference between the groups. CONCLUSION. No difference in tolerance and efficacy of nutritional support by GX versus G at a dose of 3 g.kg body wt.-1.d in oesophagectomised patients could be observed. Similar blood G profiles were in accordance with comparable glucagon and insulin levels. Because of the high standard deviations of N balances, differences in efficacy could not be proven. A significantly lower level of pseudocholinesterase (PCHE) for G40% on day 7 might indicate enhanced hepatic protein synthesis in the GX group.
