Venous perioperative nutritional therapy (PONT) has been proposed in order to reduce the catabolism caused by surgical trauma and prolonged fasting, mainly after important digestive tract surgery. Up to now it cannot be said that the criteria and real effects of this method have been completely determined. In order to identify the best composition of diets for PONT and evaluate the clinico-metabolic effects, we formulated four isoproteic, isoelectrolytic diets of different caloric composition, administered from the 2nd to the 7th post-operative day to 64 patients subjected to major digestive tract surgery. Two groups of operated patients (10 + 10) were treated with saline infusions and with Protein Sparing Nutrition. On the 7th day after the operation the patients following the four diets achieved a saving of nitrogen significantly higher than that obtained with either Protein Sparing Nutrition or saline infusions (p <0.001). This improvement in the use of nitrogen does not appear to depend on the increased caloric contribution. On the 7th postoperative day, body weight reduction in the PONT-treated patients was been to be less than in the two control groups and the fat mass showed greater saving. PONT significantly reduces catabolism caused by surgical stress in the immediate post-operative period.
