36 Preterm Nutrition
Validated Screening tools in paediatrics, recommended frequancy
STAMP: 2-17 yr, 5 steps
PYMS: 1-16 yr, 4 steps (widely adopted in UK, BMI)
Weaning PN recommendations (Infants)
Weaning PN recommendations (older children)
Weaning PN for long term HPN patients
Night off PN (may require IV fluids)
NEC Conservative Management
• NBM 5-10 days
• Parenteral nutrition
• Triple antibiotics
What’s the expected small intestinal
length for a 30 week gestation infant?
~175cm
The presence of protein and fat in the duodenum stimulate
production of ....
CCK -> gallbladder contraction
Possible Benefits of recycling stoma losses
• Improved fluid and electrolyte balance
• Faster rate of weight gain (improved capacity for absorption)
• Cessation of PN in 60% of patients
• Liver enzyme and function profiles improved
• Reduction in size discrepancy between proximal and distal bowel
• Reduction in rates of post operative anastomotic strictures and leakage
Managing IFALD
1. SMOF lipid
2. Cycle lipid component (e.g. give lipid on alternate days – 1 day on, 1 day off)
3. 3g/kg/day parenteral fat (10kcal/1g) = 30kcal/kg
Anti-infective factors in human milk
1. lactoferrin
2. immunoglobulins
Non nutritive components of formula
• Nucleotides
• Oligosaccharides
Monogen formula fat content
84% MCT
16% LCT
Trophic feeding maximum rate
12-24 ml/kg/day
Feed advancement recommendations (term vs preterm)
Preterm high risk -> 10-20 ml/kg/day
Term standard risk -> 30 ml/kg/day
Fresh MEBM vs pasteurised DEBM
MEBM higher
- micronutrients
- immunoactivite factors
- trophic factors
DEBM lower
- Microbes
DEBM criteria for eligibility
All babies < 32 weeks and or <1000g
When DEBM supply low only babies will receive it ?
High risk of feed intolerance:
<31 weeks on PN
Abdominal surgery or recovering from NEC
End diastolic flow
Growth restriction below 2nd centile
BMF recommendations
1g to 25 ml of BM
Start hen EN reach 40-100ml/kg/day
Protein hydrolysed 1.3g and 16 kcal
No iron added, provideing vitamines and minerals
Nutriprem 1 content and indications
Whole protein + 9% MCT + lactose = Osmo 310
For preterm infants, < 2Kg
Nutriprem 2 indications
Preterm infants <35 weeks, >2kg
Up to 6 months corrected age
hydrolyzed nutriprem content
EHP+ 7% MCT + lactose = Osmo 410
TPN ratios recommendations
Non-protein energy = 60-75% CHO + 25-40% lipids
AA intake = at least 1.5 g/kg/day
NPE to N : 20-30 kcal / 1g AA
Total energy: 30-40 kcal/ 1gAA
25kcal/1 g AA
AA to protein / 1.12
PN criteria
weight < or = 1.5 kg
Gestation < or = 30 +6 weeks
IUGR between 31-34 weeks or EDF or 31-37 feed not expected
NEC
IF
<37 weeks NBM for 48 hrs
When to start PN
within 6 hrs of birth or admission
Supplementary glucose % and advancement of PN in neonates 25 weeks and over
more than or = 5 days
10% glucose max rate 30 ml/kg/day
Supplementary glucose % and advancement of PN in neonates 24 +6 weeks and under
over > or = 7 days
5% glucose
Lipid rate reduced if TG level is
> or = 2.8 mmol/l
SCAMP
-Two-compartment standardised PN
-Maintenance PN bag= Glucose, protein, electrolytes, trace elements
Rate: 60 -> 75 -> 90 ml/kg/day maximum
-Lipid PN syringe= Fat, water and fat soluble vitamins
6,1 -> 12,2 -> 17ml, 3g/kg/day maximum
+Supplementary infusion of glucose 10% or 5%
+Supplementary infusion of electrolytes
- Primene amino acid course allowing longer shelf life
NEON
- Two-compartment standardised PN
- start up and maintenance bag
Depending on postnatal day of life run at a different rate
- Can use side arms of glucose 5% and 10%
x- Does not use additional electrolytes
Lower starting protein and glucose delivery than SCAMP
- Primene amino acid source- allows longer shelf life
Only licensed three compartment neonatal PN
Amino acid, glucose and lipid separately
NUMETA
Glucose Infusion Guidelines Preterm
Start at 6-9 g/kg/day (4.1–6.3 mg/kg/min)
After 4 days 9–16 g/kg/day
Maximum intake 16 g/kg/day (11 mg/kg/min)
Can you think of a candidate that would be better
on a standardised PN bag than bespoke PN
- A baby meeting nutritional recommendations and growing well on
- A baby that is extremely fluid restricted
- At a weekend or out of hours
