[Behavior of the metabolism in gastric patients during a 4-day-long postoperative complete parenteral feeding with amino acids and a glucose-levulose-xylitol combination solution].

In a clinical study we tested the following parameters: free fatty acids, beta-hydroxybutyrate, acid-base-balance, lactate, bilirubin, uric-acid, fructose, xylitole, glucose in blood and urine. The tests were executed in 9 patients who were undergoing stomac operations. The cardio pulmonary system of all patients was normal, and there was a homeostasis in water and electrolytes preoperatively. In combination with the amino-acids we received a ratio of 1:1:1 for glucose, levulose and xylitole. Totally, the patients received 0.36 g per kg body weight and per hour of carbohydrates. Beta-hydroxybutyrate, aceto-acetat, and free fatty acids show normal values under conditions of parenteral nutrition as well as lactate, uric acid, and acid-base-balance. The ratio of the different carbohydrates in serum and urine prove that the infusion time and volume were extremely favourable. The loss of carbohydrates in urine was very low.
