Malnutrition is associated with an increase in morbidity and mortality and therefore a raise in hospitalization's costs. Nevertheless, an early nutritional support can reverse this trend. Gastrointestinal dysfunctions (gastroparesis, abdominal distension, high gastric residues) in patient on enteral nutrition, may appear and very likely generate an increasing risk of regurgitations, pulmonary aspiration and infection. These symptoms represent the main factors limiting dosage in administering enteral nutrition. Prokinectics agents (metoclopramid, cisaprid and erythromycin) which improve gastric motility are often used in order to maintain enteral nutrition and to cover the energetic needs of patients. This revenue shows some way of using prokinectics in case of enteral nutrition intolerance and propose a step-by-step guideline on how to start and increase progressively enteral nutrition.
