Enteral Nutrition (EN) is a nutritional support for providing nutrients and other various nutrients needed for metabolism via the gastrointestinal tract. Enteral nutrition can be administered orally or by catheter infusion, wherein the catheter infusion includes nasogastric tube, nasoduodenal tube, nasojejunal tube and gastrointestinal fistulation tube. The critical patients can maintain intestinal mucosa barrier and promote intestinal function recovery by implementing early-stage enteral nutrition. At present, early enteral nutrition is more and more applied to clinic, but because the nutrient solution is various in types and high in fat proportion, the nutrient solution is influenced by pH value and osmotic pressure in the supplementing process, and patients are easy to have intolerance symptoms such as nausea and vomiting.
