title: [Caloric and nitrogen intake during pre- and post-operative periods. method and duration].
abstract: Preoperative nutritional support is analysed from 7 prospective studies. Clinical benefits from nutrient intake and duration are not demonstrable. In one study, preoperative long-chain triglycerides infusions are associated with more postoperative complications. Postoperative nutrition is analysed from 20 articles. No one considers the clinical benefit with regard to quantitative and qualitative intakes.
