[Glucose, fructose and xylitol as energy carriers in postoperative parenteral nutrition (comparative studies) (author's transl)].

The effects of fructose, glucose and xylitol, as well as their mixture in a proportion of 2:1:1 were measured and compared in the postoperative phase in a uniform group of patients receiving these substances during a 6-hour infusion. Carbohydrate balance, carbohydrate blood levels, changes in acid-base equilibrium and rises of lactate and uric acid were used as criteria for assessing the various substrates and their mixtures. Using these criteria, a carbohydrate mixture consisting of fructose, glucose and xylitol (2: 1: 1) proved to be better than the various substrates by themselves in equivalent amounts.
