Keppler - 2 Flashcards
fetal biometry first trimester
crown-rump length
fetal biometry second/third trimester
biparietal diameter
head circumference
abd circumference
femur length
4 tests of well being
non stress test (NST)
biophysical profile (bpp)
doppler evaluation of umbilical arteries/MCA
intrapartum continuous fetal monitoring
biophysical profile factors in (4)
movement
tone
breathing
amniotic fluid
normal NST/findings
baseline 120-160
2 or more accelerations
absent decelerations
moderate variability
at least 20 min
4 elements of NST
baseline frequency
accelerations
decelerations
variability
invasive fetal testing
amniocentesis
almost never done
what does a reactive NST demonstrate
99.8% likelihood fetus will not die w.in next week from hypoxia
what is continuous fetal monitoring (CFS)
similar to NST but intrapartum
how is CFS different from NST
real time assessment of fetus at a single point in time
4 things US evaluates
anatomy
fetal growth
fetal well being (biophysical profile/BPP)
umbilical/fetal vessel blood flow
why may amniocentesis be performed
genetic evaluation of fetus
assess fetal lung maturity
anemia in fetus
infxn in fetus
