Sucking reflex
Newborn sucks in response to a nipple in the mouth; observed by 14 wks
Rooting reflex
Head turns to the side of a facial stimulus, present by 28 wks
Traction response
The infant is pulled by the arms to a sitting position. Initially, the head lags, then with active flexion, comes to midline briefly before falling forward
Palmar grasp
Placement of examiners finger in newborn’s palm; develops by 28 wks and disappears by 4 months
Deep tendon reflex’s in newborns
A few beats of ankle clonus and an upgoing Babinski reflex may be normal
Moro (startle) reflex
Holding infant supine, allow head to drop suddenly and the arms will abduct and extend followed by adduction. this develops by 28 wks and disappears by 3 months
Tonic neck reflex
Turn infants head to one side; the arm and leg on that side will extend while the opposite arm and leg flex. Disappears by 8 months
Contraindications to early newborn discharge
- Jaundice at 24 hrs
- High risk for infection
- Known or suspected narcotic addiction or withdrawl
- Physical defects requiring eval
- Oral defects (clefts for ex)
Define “physiologic jaundice”
Visible jaundice appearing after 24 hrs of age.
Total bilirubin rises by < 5 mg/dL/day and peaks around 3-5 days of age (doesn’t usually exceed 15 mg/dL
When does physiologic jaundice usually resolve? (in full-term and pre-term)
Full-term: 1 week
Pre-term: 2 weeks
Why does physiologic jaundice peak in 3-5 days?
The liver isn’t conjugating well in the first few days of infancy.
Sepsis, trauma, etc causes increased hemolysis too
Infant needs to be eating!
Causes of pathologic unconjugated hyperbilirubinemia
- Hemolytic causes (immune mediated, non-immune mediated, sepsis)
- Non-hemolytic causes (extravascular hemorrhage, polycythemia, bowel obstruction, functional ileus, breast-feeding associated (inadequate intake of breast milk)
- Decreased rate of conjugation –> Crigler-Najjar syndrome, Gilbert syndrome, hypothyroidism
Presentation of Acute Bilirubin Encephalopathy
- Lethargy, poor feeding
- Irritability, high-pitched cry
- Arching of neck (retrocollis) and trunk (opisthotonos)
- Apnea, seizures, coma
Presentation of Chronic Bilirubin Encephalopathy
- Gaze abnormality, especially limitation of upward gaze
- Auditory disturbances
- Dysplasia of the enamel of deciduous teeth
Tx for Jaundice (2 things)
- Phototherapy
- -> Pre-term infants are at higher risk but pretty much every infant that levels greater than 20 get phototherapy - Exchange Transfusion
- -> Done once levels get above 25 after 5 days
_______ is a NEVER EVENT
Kernicterus
Hypoglycemia in infants
- Definition
- Reason why it often occurs in diabetic mothers
Definition: Blood glucose < 45 mg/dL
Diabetic mothers have high glucose –> gets passed to infant –> they become large and their insulin is working at a higher rate. When born and umbilical cord gets cut off, insulin cells don’t know to turn off and are “working overtime” creating hypoglycemia
Tx for hypoglycemia in infants
20-45 mg/dL, no symptoms = feed and frequent monitoring, if unable to feed give IV glucose
< 45 mg/dL w/ symptoms = provide glucose bolus followed by IV
< 20 mg/dL w/ or w/o symptoms = bolus followed by IV
