Pregnancy CLINICAL Flashcards
Obstetric exam key points
Note obstetric dating is from LMP, meaning conception would have occurred at least 2 weeks after.
Length of pregnancy Parity Social history Previous medical history Current medications Nature of mothers pregnancy( gestational diabetes, preeclampsia) Smoke/drink Type of delivery wanted Age
What scans would you perform?
12 weeks: would do nuchal translucency
20 weeks : anatomy scan
What is part of the fetal welfare assessment?
Closed cervix; babies bladder; placenta (whiter structure); head and abdominal circumference; fetal stomach; fetal blood flow with doppler of umbilical artery. May also do cerebral doppler
What is key with pre-pregnancy planning?
Have good health (obesity is a risk factor), also limit alcohol etc. Take folate, as NT closes at week4/4.5
What factors will someone be bringing into pregnancy?
Parity: if first time, BP so preeclampsia Family history Other medical conditions Mental health Age Partners age/history
What are you trying to detect with fetal scans?
Preeclampsia; fetal growth restriction; gestational diabetes; fetal abnormalities; risk of preterm birth; trisomy 21; congenital abnormalities
What screening tests are there and when do we do them?
1st tri: Serum PAPP-A and BHcg + nuchal translucency
2nd tri: Quad test, uES, alpha FP, bHCG, inhibin A, NIPT aneuploidy
What physiological changes are there in preeclampsia? (high BP)
Normally, feto-placental cells inade deep into the decidua.
In preeclampsia, the trophoblast invades poorly, meaning decreased utero-placental perfusion. Also endothelial dysfunction.
Syncytial knots?
Doppler and preeclampsia
Abnormal placental development- abnormal umbilical doppler, fetal hypoxemia, redistribution of flow, myocardial dysfunction
