title: [Postoperative energy requirements and its fulfillment].
abstract: After surgical procedures there are complex and typical changes of the homeostasis, which are summarized as postaggression syndrome. Energy demands in the immediate postoperative period are lower than presumed until recently. After elective surgery the basal energy requirement will increase to about 10 per cent above the preoperative level. Artificial nutrition is used in clinical practice to overcome this. Enteral and/or parenteral nutrition is necessary to meet the energy and nutritional demands in the postoperative period.
