[Hypocaloric nutrition in the early postoperative phase in patients following colorectal surgery].

In patients with colorectal tumors of stages T4 N0-N1 and M0 the effectiveness of hypocaloric nutrition in the early postoperative period was monitored. Only patients without a disturbed nutrition state in the preoperative period were selected for this procedure, in which Schmoz' 6-point-system (Hb, albumin, transferrin, anthropometries and immune state) was used for this distinction. The nutrition solution used was Infesol (40.0 g amino acids to 100.0 g sorbitol in 11). The postoperative control of protein values showed that all values were normal; only albumin decreased from the norm on the second postoperative day. Nitrogen losses in 24-h urine were on average 15 g N, with an N intake of 9.5 g daily. All patients were fed by the peripheral-venous way. Complications were minor and were favorable compared to those observed in a group given hypercaloric nutrition.
