NEONATOLOGY Flashcards
The rationale of this intervention in the Essential Newborn Care is to prevent neonatal hypothermia and to increase colonization with protective family bacteria
Uninterrupted skin-to-skin contact
ESSENTIAL NEWBORN CARE
• Immediate drying → prevents hypothermia
standard
• Uninterrupted skin-to-skin contact → 60 - 90 mins; prevents hypothermia, increases colonization with protective family bacteria and improves breastfeeding initiation and exclusivity.
• Delayed cord clamping after 1 to 3 minutes → decreases anemia in 1 out of 3 premature babies and prevents brain hemorrhage in 1 out of 2; prevents anemia in 1 out of 7 term babies.
• Breastfeeding within first hour of life prevents 19.1% of all neonatal deaths.
The target temperature for newborns is?
36.5 - 37.5°C
Mechanisms of heat loss in a newborn
(1) Convection of heat energy to the cooler surrounding air
(2) Conduction of heat to the colder materials touching the infant
(3) Heat radiation from the infant to other nearby cooler objects
(4) Evaporation from skin and lungs
Optimal method for maintaining temperature in a stable neonate?
Skin-skin contact
Low birth weight
<2,500 grams
Very low birth weight
<1,500 grams
Extremely low birth weight
<1,000 grams
Late preterm birth
Equal/>34 and <37 weeks
Very preterm birth
<32 weeks
Extremely preterm birth
<28 weeks
also known as intra-uterine growth retardation (IUGR)
SMALL FOR GESTATIONAL AGE
BW is < 3 rd percentile for calculated gestational age
SMALL FOR GESTATIONAL AGE
differentiate Symmetric from Asymmetric IUGR
LARGE FOR GESTATIONAL AGE
Birth weight of >90 th percentile for gestational age
The most important component of the APGAR score is the:
Respiration
The best description of the APGAR score is that it
. Assesses neonates in need of resuscitation
EINC TIME-BOUND INTERVENTIONS
IMMEDIATE NEWBORN CARE
APGAR scoring system
Remember when given the word “grimace” the score for that is 1
Expanded NBS covers how many diseases?
28 diseases
On what day of life is NBS done?
24 - 48 hrs of life
- Ideally done at 48 hours of life
- If blood was collected <24 hours old, repeat at 2 weeks old.
- For preterm: ideal time for NBS should be at 5-7 days old
- Can be done until 1 month old (for sick babies)
NEWBORN SCREENING TEST RA #
RA #9288
enzyme defect in MAPLE SYRUP URINE DISEASE
defective activity of the enzyme branched chain alpha-keto acid dehydrogenase complex
has a potent mineralocorticoticoid activity
11-Deoxycorticosterone
enzyme deficient in classic galactosemia
Galactose-1-phosphate uridyltransferase (GALT) deficiency
CNS + more abrupt presentation + maple syrup odor
MSUD
Galactosemia that presents with cataracts
Galactokinase deficiency (GALK)
What is the enzyme that is deficient in phenylketonuria?
Phenylalanine hydroxylase
present with unpleasant musty odor
PHENYLKETONURIA
Slate blue, well demarcated areas of pigmentation over the buttocks and back
Mongolian Spots
CNS + kidney + liver affected
Galactosemia
CNS + delayed presentation + musty odor
PKU
Cysts appearing on the hard palate which is composed of accumulations of epithelial cells.
The cheese-like material that covers the normal term infant in varying amounts:
. Vernix caseosa
The purplish reticulated pattern noted on the skin of a neonate when exposed to cold:
Cutis marmorata
Small, white occasionally vesiculopustular papules on an erythematous base develop after 1-3 days. Contains eosinophils.
Erythema toxicum
Vesiculopustular eruption over a dark macular base around the chin, neck, back, and soles. Contains neutrophils.
Pustular melanosis
Pearly white papules seen mostly on the chins and around the cheeks
Milia
Open and closed comedones or inflammatory pustules and papules on the cheeks of the baby usually after a week from delivery
Neonatal acne
Pink macular lesions on the nape, glabella, upper eyelids, or nasolabial region
Nevus simplex
Hair that covers the skin of preterm infants. Seen on term infants around the shoulders.
Lanugo
Thick, white creamy material usually absent in post term infants
Vernix caseosa
Mottling of the skin with venous prominence. Cobblestone, lacy appearance
Cutis marmorata
ABSENT MORO REFLEX
- Abnormal crepitus palpated around the clavicle
- Clavicle not clearly delineated in the skin
Clavicular fracture
ABSENT MORO REFLEX
- Arm abducted
- Pronated
- Internally rotated
- History of excessive traction on the head
- Intact hand grasp reflex
Brachial plexopathy
