The practice of postoperative artificial nutrition (PAN) in elective surgery was covered by a consensus conference in France (December 16,1994). Artificial nutrition was defined as the intake of at least two macronutrients (protein, lipid, and carbohydrate) through an artificial pathway (enteral/parenteral). The guidelines resulting from the conference (2) recommended prescribing artificial nutrition for only malnourished patients, patients with insufficient postoperative nutrient intake lasting 7 or more days, and patients with severe postoperative complications. These were similar to American guidelines produced in 1993 (1).
