[Improvement of parenteral feeding through the additional administration of a serum protein solution]

On 7 days - 5 postoperative - patients undergoing Billroth I or Billroth II were continuously infused apparatively witn an amino acid mixture of 100% and a glucose-xylitol-solution of 25% (group I). One group (group II) additionally received a serum protein solution. From the first preoperative day to the fifth day of the postoperative period we determined individual parameters in blood and urine. A decrease of serum phosphate level beginning on the first day after starting parenteral nutrition was observed. In the nitrogen balances, in total protein and albumin concentration there were no differences, but serum gamma-globulin concentration of group II was very low at the end of the parenteral nutrition period, a point which at present cannot be explained.
