[Amino acid metabolism in post-stress metabolism].

During the first four days after cholecystectomy 5 patients were nourished totally parenterally with the amino acid solution INFESOL 40 and carbohydrates. The utilization of the applied amino acids were observed by nitrogen balances, amino acid pattern in plasma and urine and other data. It was achieved a positive nitrogen balance at the 3rd postoperative day. The utilization of the amino acids typically was influenced by postaggression metabolism. For the application of INFESOL 40 in the postoperative period (posttraumatic period) some modifications of the amino acid pattern were recommended.
