Pediatric Nutrition Support Flashcards
Premature
<37 weeks gestation
When do you start PN for premature infant?
Started on day of birth
- <1800 g or 33 weeks or less
- used as supplement to enteral feedings during transition to complete enteral feedings
Types of parenteral nutrition
- starter or vanilla
- custom
- protein solution
Starter or vanilla TPN
- used in premature infants until custom TPN can be made
- dextrose and protein only
- may add calcium
Custom TPN
- customized concentrations of dextrose, protein, electrolytes
- contains vitamins and minerals
- intralipids started at this time
protein solution (PN)
- contain protein only
- used to keep lines open
When are fluids initiated in a premature infant?
1st day of life
What line does the starter TPN go into in pediatric?
UVC (umbilical venous catheter)
What line dose the protein solution go into in pediatric?
UAC (umbilical arterial catcher)
Fluid needs for preemie on day 1 of life
80 mL/kg/day
Fluid needs on 2nd day of life
100 mL/kg/day
Fluid needs on 3rd day of life
120 mL/kg/day
Fluid needs on 4th day of life
140 mL/kg/day
Fluid needs on 5th day of life
140 - 160 mL/kg/day
What are parenteral fluids used for in pediatrics?
- maintain hydration
- help stabilize electrolytes
- maintain appropriate glucose level
- aid in A/B balance
- provide adequate nutrition for proper growth and development
What component of PN is carbohydrates?
Dextrose
What is the CHO rate in PN?
Initiate @ 4-6 mg/kg/min and increase by 2-3 mg/kg/min daily
GOAL: 8-12 mg/kg/min
(Needed to maintain cals.)
What are the parenteral calorie requirements for a neonate?
90-110 kcal/kg/day
What is the goal protein level for a neonate?
4 gm/kg/day
- Blend of AAs (trophamine)
- Add L-cysteine for neonates
- Always start at goal
What is the goal lipid level for a neonate?
Initiate @ 1-2 gm/kg/day toward goal of ~3 gm/kg/day
- No less than 0.5 g/kg/day to prevent EFA deficiency
- Add L-carnitine
- Monitor TG level if hyperglycemic
What are PN additives?
- Daily vitamin/minetals
- Adjust Na, K, Mg prn
- Acetate/Chloride for Acid:Base
* 4. Goal to Max. Ca and P content for bone mineralization*
What is the most optimal source of of nutrition in a premature infant?
ENTERAL
-initiate as soon as stable @ 30 mL/kg/day and increase as tolerated
What are the goals of pediatric nutrition support?
- Provide appropriate nutrition for growth
- Preserve existing tissue stores
- Provide catch-up growth for malnourished patients and rehab of nutritionally depleted patients
- Preserve oral motor skills
What are the steps taken before PN in pediatrics?
- Oral intake
- Supplements (formulas0
- Modulars (add CHO, proteins, fats)
- Tube feedings
- PN
What are indications for TF in pediatrics?
- Neure/NM disorders with impaired swallowing/oral motor skills
- Congenital anomalies
- Increased metabolic needs
- Altered absorption/metabolism
- Growth failure
Why is EN better than PN?
- More physiologic
- Maintains GI integrity
- Decreased potential for bacterial translocation
- Decreased hepatobilliary complications
- Less expensive
- Fewer technical/infectious complications
What are contraindications of TF?
- Severe shock state
- Severe peritonitis
- Non-functional gut-ischemia, anatomic disruption, post-surg ileus
- High output fistula
- Diarrhea exacerbated by EN
