[Various metabolic effects in total parenteral feeding using a carbohydrate combination and amino-acid solution in the pre- and postoperative phase].

Ten metabolically healthy patients who had undergone gastric resection were fed intravenously from the preoperative to the 5th postoperative day. After the 24-hour preoperative infusion period the concentration of cholesterol, free fatty acids and alkaline phosphatase dropped significantly. So did the concentration of uric acid. During the postoperative period cholesterol and uric acid continued to fall. The concentration of free fatty acids remained low all the postoperative days. From the second postoperative day on the triglycerides rose continuously. Serum glutamic oxalacetic transaminase and serum lactic dehydrogenase reached their highest level on the first postoperative day. On the same day the alkaline phosphatase dropped to the lowest level. Five patients had a rise of total bilirubin up to 1.1 mg/100 at the end of the infusion period.
