Flashcards in 10 - Obs - Fetal Growth, Compromise and Surveillance - Fetal Surveillance Deck (6):
1

ID of high-risk preg - Prepregnancy - 5

poor past obs hx / v small baby

extremes of reprod age
assisted conception

2

ID of high-risk preg - During preg - 5

HTN/proteinuria
PV bleeding

Prolonged pregnancy
Multiple pregnancy

3

ID of high-risk preg - Ix - 3

cervical scan at 23 weeks
uterine artery doppler
maternal blood tests eg PAPP-A

4

Early Pregnancy Surveillance

Blood tests: ????-A = ?
hormone, level reduced in ?trim w ? abnormalities. Use in ? screening.

Maternal uterine aa Doppler: Uterine circ has v ? resistance in normal preg. Abnormal wave form at ?wks suggest failure of this, and identifies ?% pregs at risk of adverse neonatal outcomes in early ?rd trim, esp early ?, IUGR or ?.

These tests not universal but can be invaluable esp in combination.

Integrated screening for preg risk: Combo of different RFs to incr ?. So factors in Hx and invx can be used to ID more ? ? women

doppler waveforms of fetal circulation
USS - biophysical profile, liquor volume

these tests are not ? in low risk pregs - cornerstone of ID of ? or compromised fetus is serial measurement of ? ? and other aspects of ANC
