through gastrointestinal by oral use,nasogastric tube,nasointestinal tube,jejunum stoma tube,which consistent with physiology status and economic way to prove and retain energy.39Advantage Prove and retain the structural integrity of intestinal mucosa,keep the barrier function of intestinal mucosa,prevent bacterial translocdtion from intestineAdvantageous for liver to synthesis visceral proteinSurpass parenteral nutrition in keep and increase body weight with same enery and nitrogen condition40Low request for equipage and technology,more economic than parenteral nutritionPromote excrete of digestive juice and gastrointestinal hormone,and gallbladder contraction,decrease complication Promote recover of enterokinesiaAdvantage 41Principle Intestinal tract especial for small bowel have function,can absorb all kinds of nutrient;tolerance for enteral nutrition;use EN as far as possible 42Indication Dysphagia and dysmasesiaConscious disturbance and coma Alimentary tract leak:lower output fistula and later periodShort gun syndromeInflammatory bowel disease 43Pancreatitis:after intestinal function recover of acute pancreatitis,chronic pancreatic insufficiencymalnutritionHigh atabolism statusChronic wasting diseaseObstruction or operation of upper alimentary tractIndication 44Contraindication Complete mechanical ileus,bleeding of gastiointestinal,serve abdominal infectionEarly state serve stringent,shock,paralytic ileusEarly period of short gut syndrome45High output fistula of jejunalRefractoriness vomit,refractoriness diarrhea,serve enteritis,colonitisGastrointestinal function disturbance,gastrointestinal need restEarly stage of acute pancreantitisContraindication 46When to use Earlier enteral nutrition:in 24h postoperation littlemore slow fast low densitynormal densityTheory:postoperation alimentary tract parlysis main for gastric colon,small bowel recover function in 12h47Type of nutrientElemental diet:various kinds of nutrient in nature food made artifically,no need to digest,absorb directly nitrogen from amino acid serve digestive function disturbance(elental)nitrogen from aminopeptodrate light,middle digestive function disturbance(Ensure powder)nitrogen from casein normal digestive function48Homogenate diet:suitable for normal gastrointestinal function(Anso、Nutrison Fibre)Mixing Type of nutrient49Fluid choiceNormal gastrointestianl function complete protein,eg Ensure、Nutrison Fibre、homogenateLow gastrointestinal function elemental diet,eg Ensure Powder、ElentalInfusion to small bowel direct isoosmiaHypermetabolism high energy50Liver function failure less AAA,more BCARenal function failure only provide EAA,limit non-EAA,reduce accumulation of urea nitrogenFluid choice51Respiratory failure redude glucose content,vocate enteral nutrient with high fat content Strengthen immunity abound with peptide,Gln-glutamine,Arg,nucleotide,unsaturated fatty acid,vitamin C,E,A Diabetic(GLucema)Fluid choice52Infusion pathwayNasogastric tube advantage:suitable all kinds of nutrient disadvantage:back flow aspirationJejunum stoma advantage:less aspiration、long term、diet meanwhile、gastrointestinal decompression meanwhile disadvantage:need operation53Method Fractionation bolusFractionation infusionContinuous infusionInfusion pump54Notice Speed 20ml/h 100ml/hDensity
