Which is higher in premature babies, ECF or ICF?
ECF
-50% in premature babies, while ICF is 35% in premature babies
What is the calculation for % of dehydration in peds pts?
% Dehydration = (Normal wt - Actual wt)/Normal wt
What are the 3 stages of dehydration?
1) Mild
2) Moderate
3) Severe
What is the % dehydration that is mild dehydration?
<5%
What are the s/s of mild dehydration?
Normal to dry mucous membranes Slight thirst Tears present Normal skin Flat anterior fontanel Slightly increased urine specific gravity
What is the % dehydration that is moderate dehydration?
6-9%
What are the s/s of of moderate dehydration?
Irritable Moderate thirst Dry mucous membranes With or without tears Anterior fontanel may or may not be sunken in Skin +/- Increased urine specific gravity
What is the % dehydration that is severe dehydration?
10-15%
What are the s/s of severe dehydration?
Hyperirritable to lethargic Intense thirst Parched mucous membranes Absent tears Sunken anterior fontanel Tenting skin Significantly increased urine specific gravity
T/F: Clear liquids are always super helpful.
FALSE
-Misconception that they are helpful
Why are clear liquids not always helpful?
B/C they are hyper-osmolar and lack electrolytes
What should be used instead of clear liquids in dehydration?
Glucose-Sodium coupled transport mechanism
-Ration of 1 - 2:1 (glucose:Na)
What is the concern with more osmolar liquids?
DIARRHEA
When do you refer to MD for dehydration?
Young age (<6 months, <8kg) High risk - DM Fever >38 C for infants <3 months or >39 C for infants 3-36 months Visible blood in stool, high output Persistent vomiting Change in mental status
When does mild to moderate dehydration begin?
AT HOME
What is the ORS dosage for rehydration in mild to moderate dehydration?
50-100 mL/kg over 4 hours
Over how many hours should ORS be given in mild to moderate dehydration?
OVER 4 HOURS
How many mL per kg of body weight or ORS should be given in mild to moderate dehydration?
50-100 mL/kg body weight
In mild to moderate replacement of losses, how many mL should pts weighing <10 kg receive?
60-120 mL ORS for each diarrheal stool or vomiting episode
How many oz is 60-120 mL ORS?
2-4 oz
In mild to moderate replacement of losses, how many mL should pts weighing >10 kg receive?
120-240 mL ORS for each diarrheal stool or vomiting episode
How many oz is 120-240 mL ORS?

T/F: During oral rehydration you can consume lactose.
FALSE
-Avoid lactose
During oral rehydration, what foods should older children avoid?
Foods high in simple sugars
- Soft drinks
- Undiluted apple juice
- Jell-o
- Presweetened cereal
Why is the BRAT diet not recommended for prolonged use?
Inadequate energy and protein content
What are the must use IV rehydration conditions?
Bloody diarrhea
Severe dehydration (shock or near shock, >10% fluid deficit)
If pt has an intestinal ileus
Intractable vomiting
High stool output (>10 mL/kg/hr) associated with lower rate of success with ORS
Who has the most maintenance caloric requirements?
Premature neonates
-The younger you are the more you get
What are the advantages of enteral over parenteral nutrition?
- Maintenance of structural and functional GI integrity
- Decreased potential for bacterial translocation
- Enhanced utilization of nutrients; improved glucose tolerance and decreased hyperinsulinemia
- Greater ease and safety of administration
- Decreased hepatobiliary complications associated with TPN
- Decreased cost
Name the indications for Enteral Nutrition.
Diminished ability to ingest nutrients
Failure to meet full nutritional needs orally
Altered absorption or metabolism of nutrients (chronic diarrhea, short bowel syndrome, inflammatory bowel disease, GERD)
Name the contraindications to Enteral Nutrition.
Necrotizing enterocolitis GI obstruction Intestinal atresia Severe inflammatory bowel disease Acute pancreatitis
What macronutrient do you consider most important for the development of an infant?
PROTEIN
What minerals and vitamins become exceedingly important for a premature infant?
Ca
Vitamin D
Phosphorus
What is the gold standard feeding for babies?
Breast milk
T/F: Breast milk provides immunologic protection.
TRUE
How long does the American Academy of Pediatrics recommend breast feeding?
For the first 6 months of life and continuation for the second 6 months as optimum nutrition in infancy
Name the benefits of breast milk.
- Optimum nutrient for term and near term infants
- Anti-infective properties reduce instances of bacterial and viral illnesses
- Suggested to lower the risk of immune-mediated dx (Crohn’s disease, DM, Eczema, Asthma, Allergic gastroenteritis)
- Psychological and long-term cognitive advantages
Name the contraindications to breast feeding.
- Contagious lesions on the breast (syphillis or herpes)

- Pertussis
- Cytomegalovirus
- TB
- HIV
- Hep B if untreated
