Enteral Nutrition in Paediatric EN in PAEDIATRICS Lecture objectives Nutritional support in children EN: Indications & contraindications How to choose site & route Selection of formula Complications Nutritional Support in Sick Children GOALS To provide energy & nutrients to support: optimal growth neuromotor development minimize gastrointestinal symptoms promote normal feeding habits & skills To treat a disease (food allergy in infants, Crohns disease......) Nutritional Interventions in Sick Children Depend on: Age Clinical picture Possibility of oral intake Absorptive & digestive capacity Dietary habits Costs Management strategy: nutritional counselling Get children eat more without unnecessary restrictions simplest, cheapest & safest nutritional support Provide oral nutritional supplement 1. - whole protein based, pediatric formula, nicely flavored, with fibers 2. - energy enriched ( kcal/ml) if more energy required Enteral Nutrition DEFINITION Feeding directly into stomach or duodenum / jejunum over tube or stoma Oral provision of dietary foods for special medical purposes EN vs. PN: Rule of Thumb improves GUT function limits bacterial translocation & sepsis decreases incidence of multiorgan failure less expensive ENTERAL INTAKE Use GUT whenever possible & as much as possible EN in Paediatrics W H E N??

Formula administration is initiated at 100 to 150 mL per feeding aspiration Continuous enteral feeding Continuous drip infusion of formula requires a pump.
