[Parenteral nutrition "à la carte" in major abdominal surgery with mixtures of Totamine concentrate and Vintène. A clinical study based on nitrogen balance].

The authors present a series of thirty patients who underwent major abdominal surgery. Each patient received preoperative total parenteral nutrition (TPN) during bowel preparation. After the operation the TPN was continued immediately, even if reanimation was necessary. The dosages of nitrogen and calories were individually adapted in function of the daily calculated nitrogen-balances. So the authors were able to administer a TPN "a la carte" using eight solutions mixed in a single bag, containing amino-acids (varying between 6 and 20 g of nitrogen), glucose (ad 150 Kcal/gN) lipids (constituting 40% of the calorie-intake), ions, vitamins and oligoelements. With a follow-up of minimum 10 days, the study proves the possibility of creating positive nitrogen-balances in 87% of the cases and an acceptable deviation in the daily measured glycemia and plasma-ionograms.
