Nutrition périopératoire : protocoles de soins

Based on texts written by experts, the objective of this paper is to propose a practical approach to nutrition for clinicians, according to the nutritional status of patients and the evaluation of surgical risk. Any patient with a nutritional grade greater than or equal to 2 should benefit from nutritional support. Indeed, current data confirm that preoperative and early nutritional support in surgery at risk can reduce significantly postoperative morbidity for patients with non-malnourished (immunonutrition in cancer surgery GI), and the morbidity and mortality in malnourished patients (enteral nutrition when possible). A preoperative oral intake is recommended 2 to 3 hours before elective surgery for clear fluids and 6 hours for a light meal. Moreover, a preoperative oral intake of carbohydrates (maltodextrin 12.5%) is recommended (except in diabetic patients). Postoperatively, early oral feeding (within 24 hours) is recommended in the absence of cons to surgery. Glutamine is recommended in case of postoperative complications.
