Q

discharge screening:

newborn metabolic disorder screening

A
  • 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

Q

NBS result treatments

A
  • Institute immediate treatment for a positive screen for:
      • Galactosemia
        • Rare auto recessive met disorder, can’t metabolise sugar galactose
      • Maple Syrup Urine Disease (MSUD)
        • Rare auto rec metabolic disorder
        • Can’t metabolize amino acids causing sweet ordor or newborn urine
    • 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

Q

Discharge screening:

Glucose screening

A
  • 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

Q

discharge screening:

jaundice screening

A
  • 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

Q

ALWAYS get family history! Did mom have a previous child that had hyperbilirubinemia?

A

Q

discharge screening:

hearing loss

A
  • 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

Q

discharge screening:

when to do congenital heart disease screening

A
  • 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

Q

how to screen for congenital heart disease

A
  • 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%

truncal incurvation/galant reflex resolves by
4 months
26
babinski reflex
* occurs after the sole of the foot has been firmly stroked. The big toe then moves upward or toward the top surface of the foot * Positive babinski is normal up to 2 years of age, diminishes after 1 yr
27
CN 1
CN 1 = alcohol pad to nose = grimace/make a face
28
CN II
blink in response to bright light (optic blink reflex) recognition of objects introduced into visual fields
29
CN III, IV (4), VI
pupillary response to light, extra ocular movements tracking, ptosis vestibulo-ocular reflex (doll’s eyes maneuver). When the head is turned, there is conjugate eye movement in the opposite direction.
30
CN VII
Crying - symmetry of facial expressions
31
CN V
light facial touch and assess response
32
CN IX, X
quality and strength of crying symmetrical rise of soft palate, gag reflex
33
CN V, VII, IX, X
Feeding - sucking and swallowing
34
CN VIII
response to sound made outside of visual fields clap → blink → hearing intact
35
Common NB skin findings
* acrocyanosis * harlequin sign (unilateral color change (LBW)) * erythema toxic * milia * mongolian spots * **\*\*strawberry hemangioma (refer orbital/large hemangioma or in airway)** * nevus simplex * **\*\*cafe au last spots( \> 6 greater than1 cm = w/u for neurofibromatosis)** * port wine stain * stork bites * lanugo (premie) * linea nigra * vernix caseosa * neonatal acne
36
abnormal skin findings immediate referral for workup
* **Petechiae** * Normal on presenting parts * Resolve 24-48 hrs * If head down from vaginal delivery, expect petechiae on head but if breech or c section, see petechiae on butt * But if see it ANYWHERE else = sx’ of infection * Doesn’t grow; don’t get new sites * rule out sepsis and TORCH * **Vesicular rash** * HSV and varicella → clustered vesicles a few days after birth * if high suspicion → start IV acyclovir ASAP! (dont need culture first) * Bacterial infections like staph and strep
37
still's murmur
* most common innocent heart murmur, vibratory and musical in nature, along left sternal border, louder when supine
38
pathologic murmur red flags
**holosystolic, diastolic, grade 3 or higher, harsh** * **PDA**: continuous machine-like murmur, * Heard best at left sternal upper Sternal Border * **ASD**: grade 2 or 3 systolic ejection murmur, ULSB, split S2 * **VSD**: harsh holosystolic, LLSB, sometimes can palpate thrill * If can palpate thrill, the intensity is at least grade 4 / 6
39
cephalohematoma is a risk factor for
jaundice and sepsis
40
ear pits/tags evaluate
* hearing and renal system * Assess placement of ear by drawing Imaginary line to inner campus to outer campus of the eye to occipitus * If top of pinna ear touches imaginary line = ear is correctly placed
41
light spot /leukocoria can indicate
retinoblastoma - refer!
42
diastasis recti
1 cm gap, bulges when cries, resolves in 1 week
43
* Cryptorchidism
failure to descend is associated with increased risk of testicular cancers and reduced fertility (should descend by 3-6 months- orchiopexy if not descended by 1 yr)
44
* If patient has bilateral undescended testes with micropenis, or bifid scrotum * or fused labia / clitoromegaly
prompt eval for ambiguous genitalia
45
torticollis
* twisting of neck * most common in Multiple sclerosis anomaly * Assess for torticollis by parent “does the infant only look 1 way , sleep 1 side, feed 1 direction, or holding head like that? * Birth trauma of sternocleidomastoid, can lead to plagiocephaly (flat head from toricollis = misalignment of ear) and ear misalignment * Send to PT for correction
46
maneuvers for hip dysplasia
* Barlow → dislocate * ortolani → relocate * symmetry of skin folds (gluteal/ femur) * feet: size, shape, positioning
47
parental discharge education
* **General care of infant**- bathing, diapering, cord care, circ care, temperature * **Infection control-** handwashing, caregiver vaccinations * **Feeding-** breast/bottle, schedule, burping, storage, concerning patterns * **Elimination-** voiding/stooling with each feed, concerning patterns * **Sleep-** positioning, location * **Safety-** car seat, fall prevention, siblings, pets, CPR, Emergency Services contact information
48
dialysis recti and umbilical hernias are more common in
premature infants
49
Most formula-fed infants will feed at least
8x a day on average, FF infants take 2.5 oz formula for every lb of body weight
