Flashcards in 10 - Obs - Fetal Growth, Compromise and Surveillance - Fetal Surveillance Deck (6):
ID of high-risk preg - Prepregnancy - 5
poor past obs hx / v small baby
heavy smoking/drug use
extremes of reprod age
ID of high-risk preg - During preg - 5
ID of high-risk preg - Ix - 3
cervical scan at 23 weeks
uterine artery doppler
maternal blood tests eg PAPP-A
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
6 methods of fetal surveillance
USS - fetal growth
Doppler umb a waveforms
doppler waveforms of fetal circulation
USS - biophysical profile, liquor volume
