[Metabolic behavior in pre, intra, and postoperative total parenteral feeding with a carbohydrate combination and amino acid solution].

Ten metabolically healthy patients who had undergone gastric resection were fed intravenously from the preoperative to the 5th postoperative day. No metabolic alternations were observed by using a low dosis of 0.12 mg/kg.h of glucose, fructose and xylitol in combination with amino acids. We were able to limit the so-called postaggressive syndrome by eliminating the fasting state. These results were proven by evaluating the most important metabolic parameters like triglycerides, free fatty acids, lactate and by measuring the carbohydrate-nitrogen balances.
