Fetus Flashcards
What is associated with increased AFP
RAIN
Renal (nephrosis, renal agenesis, polycystic kidney)
Abdominal wall defect
Incorrect dating/ multiple gestation
Neuro (anencephaly and spina bífida)
Why does the non stress test measure
Fetal autonomic nervous system integrity
What does the stress test measure
Uteroplacental insufficiency and tolerance of labor
Components of the biophysical profile
Fetal movement Reactive HR Breathing Tone Volume of amniotic fluid
The risk of RDS is increased with
Infants of diabetic mother
C section delivery
Birth asphyxia
The risk of RDS is decreased with
Prolonged rupture of membranes
Prenatally administered steroids
Weight for LGA and SGA babies
LGA > 3900g
SGA< 2500g
Exam findings on a post term baby
2 wks past 40 is post term
Dry skin that is peeling, long fingernails, decreased lanugo on the back, ears have strong recoil.
Long term complication of NEC
Intestinal strictures
What reduces the incidence of neonatal jaundice
Maternal heroin use
Smoking, alcohol
Phenobarbital and phenytoin
When does breast milk jaundice vs breastfeeding jaundice present
Breast milk - 6th to 14th day and can persist for 1-3 months
Breastfeeding - first days of life.
When does physiologic jaundice present
Day 2-5 peaks day 3. May last 1 week.
Factors that worsen neonatal jaundice
Sulfonamides because they bind albumin so less bili bound to albumin, severe acidosis for same reason.
PDA because blood shunted away fro liver resulting in decreased metabolism
Causes of indirect hyperbili
LIE and GLOW
Lysed blood cells (hemolysis, defect of red cell metabolism, isoimmunization)
Increased
Enterohepatic circulation (obstruction, pyloric stenosis, meconium ileus, ileus, hirshsprung) / endocrine (hypothyroid, hypopituitarism)
GIlbert disease
Lucy Driscoll syndrome
bOth direct and indirect (galactosemia, tyrosinosis, hypermethioninemia, CF)
Wasted blood (petechia, hematomas, hemorrhage, cephalohematoma, swallowed maternal blood)
Normal fetal scalp pH
> 7.25
