[Safeguarding the postoperative protein balance. Clinical studies on intravenous feeding]

In a randomized controlled study the influence of a low concentrated amino acid-carbohydrate solution (PE 900 with 25 g x 1(-1) amino acids and 50 g x 1(-1) Polyols) on the nitrogen support is investigated in the postoperative metabolism. The solution has a low osmolality of approximately 600 mosm x kg-1 and is, therefore, applicable during longer time via peripheral veins. Nitrogen retention was with 68% rather good. The effect of the regimen on protein and amino acid status is measured and discussed in detail.
