Abstract [en]

Background: The effects of immediate postoperative enteral nutrition on postoperative nitrogen balance and insulin resistance were studied in patients subjected to an enhanced-recovery protocol.

Methods: Eighteen patients undergoing major colorectal surgery in an enhanced-recovery protocol were randomized to immediate postoperative enteral feeding for 4 days with either complete or hypocaloric nutrition. Nitrogen balance and changes in glucose kinetics, substrate utilization (indirect calorimetry) and insulin sensitivity (hyperinsulinaemic-euglycaemic clamp) were measured. Values are mean(s.e.m.).

Results: Mean postoperative urinary nitrogen losses were low (10.7(1.0) versus 10.5(0.7) g per day for complete versus hypocaloric nutrition) and insulin resistance was insignificant (-20(7) versus -27(11) per cent), with no difference between groups. Complete enteral feeding was given without hyperglycaemia (blood glucose concentration 5.8(0.4) versus 5.0(0.4) mmol/l) and resulted in nitrogen balance (+0.1(0.8) versus -12.6(0.6) g nitrogen per day; P < 0.001).

Conclusion: This enhanced-recovery protocol was associated with minimal postoperative insulin resistance and nitrogen losses after surgery. Immediate postoperative enteral nutrition was provided without hyperglycaemia and resulted in nitrogen balance.
