1 Pediatric Nutrition Care as a strategy to prevent hospital malnutrition Div Pediatric Nutrition and Metabolic Diseases Dept of Child Health

2 Child is not a miniature adult Specific for child growth and development Child & Adolescent Pediatric stages development Infancy (<1 yr) Toddlerhood (1-2 yr) Preschool (3-5 yr) School age (6-9 yr) Adolescent (10-20 yr) Early adolescence (10-13 yr) Middle adolescence (14-16yr) Late adolescence (17-20 yr)

3 Patient care Medical care Drugs or surgery Nursing care Intensive care? Nutrition care goal? Healthy child optimal growth & development Outpatient child prevention of failure to thrive Hospitalized child prevention of hospital malnutrition

4 Why is nutrition important? Energy of daily living Maintenance of all body functions Vital to growth and development (infant, children & adolescent) Therapeutic benefits Healing Prevention

6 Problem? Hospital malnutrition: malnutrition during hospital admission Hospitalized children up to 54% are malnourished, globally Pediatric Ward RSCM (Ginting & Nasar, 2000) 53% of of them experiencing decreased BW hospitalized children was malnourished 15,4% of them experiencing decreased BW 35,8% only consumed < 2/3 of hospital food served Pediatric surgical ward RSCM (2004) 52.4% were malnourished 3.9% of them experiencing decreased BW

8 Factors that cause malnutrition Nutrition care? Unawareness of malnutrition by physician Inadequate skill, knowledge and management strategies of nutrition therapy High cost of nutrition support Complication associated with nutrition support, etc

9 How to solve the problem? To organize nutrition care team Physician Nurse Dietitian Pharmacist To perform nutrition care activities Nutritional assessment Nutritional requirements Routes of delivery Formula/IVF selection Monitoring

10 Nutritional assessment

11 Levels of assessment of nutritional status in clinic Dietary assessment Laboratory assessment Anthropometric assessment Clinical assessment Inadequate intake Malabsorption Increased requirements Increased excretion Increased destruction Depletion of reserves Physiologic and metabolic alterations Wasting or decreased growth Spesific anatomic lesions

12 Nutritional status interpretation If all 4 modalities can be performed more accurate diagnosis can be determined The fact : very difficult clinically + simple anthropometry

13 Assessment anthropometrics for individual nutritional status Weight for height (BMI for Age - CDC 2000) parameter overweight & obesity <5 th percentile underweight 5 th - <85 th percentile normal variation 85 th - <95 th percentile overweight 95 th percentile obese Percent ideal body weight (Olsen et al, 2003)

14 Body mass index for age percentiles {Weight(kg)/Height(m) 2 }

15 Assessment anthropometrics for individual nutritional status Weight for height (BMI for Age - CDC 2000) parameter overweight & obesity <5 th percentile underweight 5 th - <85 th percentile normal variation 85 th - <95 th percentile overweight 95 th percentile obese Percent ideal body weight (Olsen et al, 2003)

16 Standard Growth Chart The NCHS (2000) standards have been recommended for worldwide use by the WHO regardless of racial or ethnic origin Infants with a history of premature birth should have their chronological age corrected by gestational age until age 24 months for weight measurements, 40 months for length, and 18 months for head circumference

17 Percent of Ideal Body Weight (IBW) Percentage of the child s actual weight compared to ideal weight for actual height (Goldbloom, 1997) Percent of IBW the best index & reflect nutritional status better (McLaren & Read, 1972) IBW is determined from the CDC growth chart (Olsen et al, 2003) Plotting the child s height for age Extending the line horizontally to the 50 th percentile height-forage line Extending the vertical line from the 50 th percentile height for age to the corresponding 50 th percentile weight, noting this as IBW Percent IBW is calculated as (actual weight divided by IBW) X 100%

18

19 Nutrition status as percentage of Ideal Weight Weight for Height the best index & reflect nutritional status better (Waterlow, 1972) 120% obesity % overweight % normal 80-90% mild malnutrition 70-80% moderate malnutrition 70% severe malnutrition.

20 Nutritional requirement

21 Calculation of energy requirement Indirect calorimetry the most accurate method Harris-Benedict equation (BEE) Schofield equation (BEE) RDA simplest method Age (year) RDA (kcal/kg Wt) M : F : M : F : 40-50

22 Indication Calculation of Catch-Up Growth requirement in the Infant and Child Children who are below normal growth parameters due to chronic undernutrition or illness affecting their nutritional intake and status require additional calories and protein to achieve catch-up growth. Kcal = RDA (kcal/kg) for height age* x Ideal weight (kg)** * Age at which actual height is at the 50th %-ile ** Ideal weight for actual height

23 Nutritional status & requirement A, 2 y old boy Wt : 10 kg (< P 3 ) Ht : 85 cm (=P 25 ) Nutritional status W/H :10/12.2 (82%) H 50 th percentile age 21 mos RDA 100 kcal/kg Requirement 12.2 x 100 kcal/kg = 1220 kcal

24 Determining Calorie and Protein Needs in Critically Ill Children Estimate basal energy needs (BEE) WHO equations Schofield equations Harris Benedict equations (not recommended for use in pediatrics derived from adult measurements) Determine Stress Factor - Total Calories = BEE X Stress Factor Estimate patient's protein requirements Total Protein = Protein RDAs X Stress Factor Continue to evaluate and adjust recommendations based on nutrition monitoring.

25 Table 2. Determining Stress Factor Clinical Condition Stress Factor Maintenance minus stress Fever Routine/elective surgery, minor sepsis Cardiac failure Major surgery Sepsis Catch-up Growth Trauma or head injury % per degree > 37 C

26 Route of delivery and type of food/formula/iv fluids

27 Nutrition Support A variety of techniques available for use when a patient is not able to meet his or her nutrient needs by normal ingestion of food Options: Nutritional supplement to oral diet Formula fed by tube into GI tract (enteral feeding) Nutrients into venous system (total parenteral nutrition - TPN)

28

29 What you should know about enteral feeding? Benefit of enteral feeding compare to parenteral feeding When child need tube feeding How to choose route of delivery Nasogastric, orogastric, gastrostomy, transpyloric Continuous or intermittent feeding Types of enteral formula Polymeric, oligomeric (elemental), modular Guidelines of formula selection Patient factor or formula factor Monitoring Efficiency & Complications

30 Feeding routes of delivery

31

32 Gastrostomy

33 What you should know about parenteral nutrition? Indication of parenteral feeding Types of parenteral feeding Composition of parenteral nutrition for infant and children compared to adult Monitoring : Efficiency & Complications

35 Pediatric parenteral amino acid solution Cysteine, taurine, tyrosine, histidine are conditionally essential in neonates and infants Infant Primene 5% (Baxter ) Aminosteril Infant (Fresenius ) Pediatric Aminofusin Paed (Baxter ) Aminosteril (Fresenius )]

36 Complication of nutritional support

37 Refeeding Syndrome metabolic complication associated with giving nutritional support (enteral or parenteral) to the severely malnourished Starved cells take up energy substrates rapid fluxes in insulin production in response to CHO load hypophosphotemia and hypokalemia. Control by giving formula meeting 50-75% of need and advance gradually and monitoring electrolytes

38

39 Practice Guidelines for Pediatric Nutrition Care Detect actual or potential malnutrition at an early stage Patients considered malnourished or at risk if they have inadequate intake for 7 days or if they have loss 10% of their pre-illness body weight Prevent or slow malnutrition by giving nutrition counseling and diets Patients who cannot maintain adequate oral intake and are candidates for nutrition support should be considered for tube feeding first

40 Practice Guidelines for Pediatric nutrition care Enteral feeding and parenteral nutrition should be combined when enteral feeding alone is not possible Parenteral nutrition should be used alone when enteral feeding has failed or when enteral feeding is contraindicated Malnutrition should be corrected at a judicious rate and overfeeding avoided
