Week 11 Examining NB Flashcards
Prep for discharge: Eyes & Thighs
- eye prophylaxis first hour of life (erythromycin or tetracycline) to prevent chlamydia / gonorrhea conjunctivitis
- NB immature hepatic systems → bleeding risk
- thighs; vitamin K & hepatitis B vaccine
- vit K w/in 1-6 hrs after birth
- hep b: first 24 hrs
Gonorrhea conjunctivitis can lead to
blindness
chlamydia conjunctivitis can lead to
pneumonia
single vitamin K injection lasts
til 6months until solid foods
vitamin K doesn’t cross placenta and not in breastmilk/formula
For Infants Born to Hepatitis B NEGATIVE mother
- give vaccine if > 2000 grams within the first 24 hours
- if < 2000 grams- (4lbs 4 oz)
- administer at 1 month of age or at hospital discharge, whichever comes first
- 1 kg = 2.2 lbs
- 1000 g = 1 kg = 2.2 lb
- **many women asymptomatic that have hep B
For Infants Born to Hepatitis B POSITIVE mother
- Administer Hepatitis B vaccine to all infants within the first 24 hours regardless of weight
AND
- Administer Hepatitis B immunoglobulin
discharge screening:
newborn metabolic disorder screening
- Metabolic, hormonal, hematologic, infectious
- Recommended Uniform Screening Panel (RUSP) aka Newborn Screen (NBS) has 35 core conditions, 26 secondary conditions
- Simple heel prick between 24-48 hrs after birth. Drops of blood are blotted on a special absorbent filter card
- Air dry for 4 hours → state’s Newborn Screening lab- takes 10-14 days for results
Factors that can affect Newborn metabolic screening (NBS) results
- obtaining too early
- Before 24 hrs of life
- antibiotics
- blood transfusion
- failure to wipe away first drop of blood
- not enough feeding
- inadequate sample
NBS result treatments
- Institute immediate treatment for a positive screen for:
- Galactosemia
- Rare auto recessive met disorder, can’t metabolise sugar galactose
- Galactosemia
- Maple Syrup Urine Disease (MSUD)
- Rare auto rec metabolic disorder
- Can’t metabolize amino acids causing sweet ordor or newborn urine
- Maple Syrup Urine Disease (MSUD)
- Excluding these 2; this is SCREENING test. All other +’s need more testing to confirm
- Otherwise no treatment for any other + screening results until further testing confirms diagnosis
Discharge screening:
Glucose screening
- Glucose tends to drop 25 mg within the first 1-2 hours after birth
- after 4 hrs, 25-35g is threshold, then > 45g
- Screening NOT rec for healthy full term infants
- At risk infants need screening if:
- Diabetic or GD- baby used to increased glucose so has increased insulin levels at birth
- Preeclampsia/HTN
- Substance abuse
- Exposure to medications (tocolytics, glucose)
Neonate
- Prematurity- esp late preterm 34-37 weeks
- LGA or SGA
- HIE event or birth injury
- Sepsis
- Congenital cardiac, endocrine, inborn errors of metabolism disorders
- if infant is showing signs/sx’s of hypoglycemia..?
- what if there are no sx’s but low blood sugars?
- give IV glucose!
- if not showing sx’s, recommend feeding
s/sx hypoglycemia in neonates
- Most Common:
- Irritability
- Tremors
- Severe: Lethargy, changes in LOC
- Can also be seen:
- Seizures
- Hypotonia
- Feeding difficulty
- Respiratory distress
- High pitched cry
discharge screening:
jaundice screening
- using transcutaneous hyperbilirubinemia or jaundice monitor or blood draw
- If discharged sooner than 72 hours→ do at primary care office
- F/u in 1 -2 day
- High levels of unconjugated bilirubin lead to jaundice from immature hepatic system and lack of PO
- Screen if “too high too soon” or shows up w/in first 24 hrs → pathologic cause than physiologic
- Jaundice goes head to toes
- further down body = higher the level of bilirubin
ALWAYS get family history! Did mom have a previous child that had hyperbilirubinemia?
- If yes, that’s a huge risk factor for future pregnancies
discharge screening:
hearing loss
- Otoacoustic Emission Test (OAE) [top pic]: using probe in ear measures ciliary hair movement
- Automated Auditory Brainstem Response (AABR) [bottom pic]:
- Measures acoustic nerve and brain respond to sound. Tones are played through headphones and electrodes measure brain’s response to sound.
- If no pass initial hearing screen → repeat testing within 3 months
- Goal: screen by 1 month, identify deficit by 3 months, be receiving services and/or treatment by 6 months of age
discharge screening:
when to do congenital heart disease screening
- Clamp umbilical cord → the transition from fetal circulation to neonatal circulation
- Arteries and veins constrict and systemic blood pressure increases
- When systemic vascular resistance > pulmonary vascular resistance the 3 major fetal shunts close
- Ductus Venosus
- Foramen Ovale
- Ductus Arteriosus
- Screening is performed after 24 hours of life to detect any potential congenital cardiac anomalies
how to screen for congenital heart disease
- screen AFTER 24 hours of birth, before discharge
- Pre and postductal pulse oximetry screening
- Right hand and Left foot test both at the same time
- Normal results: both hand and foot 95% > and < 3% difference between them
-
Discrepancies should receive urgent referral to pediatric cardiology
- If < 95% or difference hand/foot sat > 3%
Newborn Discharge Criteria
- Stable vital signs
- Axillary temp 36.5-37.4 C
- RR <60
- No signs of distress
- HR 80-180 bpm
- Established Feeding
- At least 2+ feedings
- Established Elimination pattern
- At least 1 void and 1 stool
- Screening and therapies completed
- Parent education completed
Rooting lasts until
4 months
