Neonatology Flashcards
The significance of having delayed cord clamping is to
Decrease incidence of anemia
This intervention in the EINC is to prevent neonatal hypothermia and to increase colonization with protective family bacteria
Uninterrupted skin to skin contact
Breastfeeding must be done within hour many hours of life?
1 hour
Mechanism of heat loss from the cooler surrounding air
Convection
Mechanism of heat loss from the colder materials touching the newborn
Conduction
Mechanism of heat loss from the infant to other nearby cooler objects
Radiation
Optimal method for maintaining temperature in a stable neonate?
Skin to skin contact
Also known as IUGR
BW is <3rd percentile for calculated gestational gestational age
Small for gestational age
LGA babies are at risk for
Hypoglycemia
Polycythemia
This type of IUGR is associated with genetic and metabolic conditions and seen early in gestation
Symmetric
This type of IUGR is associated with poor maternal nutrition
Weight is more affected
Fetus affected in late gestation
Asymmetric
Most important component of the APGAR score
Respiration
Diseases Included in the basic newborn screening
Congenital hypothyroidism Congenital adrenal hyperplasia Galactosemia Phenylketonuria G6PD Maple Syrup Urine
When is NBS screening done
24-48 hours after feeding
If NBS is done <24 hours, it must be repeated after
2 weeks
What is the ideal time to do NBS in preterms?
5-7 years old
1st physical sign of a suspected congenital hypothyroidism baby
Prolonged jaundice
Most common cause of congenital hypothyroidism
Thyroid dysgenesis
Autosomal recessive disorders of cortisol biosynthesis
Congenital adrenal hyperplasia
Most common enzyme deficiency in congenital adrenal hyperplasia
21-hydroxylase
Newborns with CAH are normal at birth but exhibit sexual and somatic precocity within
The 1st 6 months of life
Elevation in 17- hydroxyprogesterone is seen in how many days of life
2-3 days of life
Dexamethasone given prenatally can supress androgens and prevents virilization in females if given by
6 weeks AOG
Sodium and potassium levels in CAH are
Decreased- Na
Increased-K
This disease detected in newborn screening is an absolute contraindication to breastfeeding
Galactosemia
Classic form of galactosemia
Galactose 1 phosphate uridyltransferase deficiency (GALT)
This enzyme deficiency in galactosemia presents with cataracts
Galactokinase deficiency
Without the enzyme in galactosemia, galactose will accumulate in these organs
Brain
Kidney
Liver
Patients with galactosemia are at increased risk for this bacterial sepsis
E.coli neonatal sepsis
What product of the pentose phosphate pathway counteracts oxidative stress that is lacking in G6PD deficiency?
Reduced glutathione
Enzyme deficiency in phenylketonuria
Phenylalanine hydroxylase
Cheese like material that covers normal term infant in varying amounts
Vernix caseosa
Purplish reticulated pattern noted on the skin of a neonate when exposed to cold
Lacy cobblestone appearance
Cutis marmorata
Slate blue well demaracated areas of pigmentation over the buttocks and back
Mongolian spots
Red, sharply demarcated area 1/2 of body, due to imbalance of cutaneous blood vessel tone, premature hypothalamus
Harlequin color change
Small, white occasionally vesiculopustular papules on an erythematous base that contains eosinophils and develop after 1-3 days
Erythema toxicum
Vesiculopustular eruption over a dark macular base around the chin, neck, back and soles. Contains neutrophils
Pustular melanosis
Cysts appearing on the hard palate which is composed of accumulations of epithelial cells
Epstein pearl
Pearly white papules seen mostly on the chin 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
Common cause of neonatal acne
Maternal estrogen transfer
Hair that covers the skin of preterm infants; seen on term infants around the shoulders
Lanugo
