Clinical Pregnancy Flashcards
How does gestational diabetes lead to macrosomia
sugar crosses placenta at 12 wk
- fetus makes insulin –> GH spike to compensate
- macrosomia spike
How does gestational diabetes lead to macrosomia

Screening for DM in normal moms
glucose tolerance test at 24-28 wk
Positive glucose tolerance test
130 mg/dL one hour after 1 hr 50 g sugar
+ screening –> do 3 hour confirmatory test
Definition of preterm labor
less than 37 wk
Screening for DM in normal moms
glucose tolerance test at 24-28 wk
Fetal fibronectin assay
utility
adhesive of fetal membranes do decidua
good negative predictive value
-> if negative, low risk of progressing to labor
Post -partum management of moms who had gestational diabetes
50% of T2D in 5-10 yr
screen at 3 yr intervals
Speculum in preterm labor
culture and fetal fibronectin screening
Cerclage
stitch in cervix
Fetal fibronectin assay
utility
adhesive of fetal membranes do decidua
good negative predictive value
-> if negative, low risk of progressing to labor
Cerclage: what is that
stitch put in cervix
trying to push off the delivery
HIV Tx in pregnancy
same as other times
Chlamydia Tx in pregnancy
erythromycin or
azithromycin or
amoxicillin
Infection with this disease during pregnancy can lead to sensorineuronal hearing loss, cardiac defects, etc
rubella
First step in management of antepartum bleeding
ultrasound
don’t do a bimanual exam right away because you might damage the placenta if it’s placenta previa
Common causes of:
painLESS bleeding
painFUL bleeding
painless: placenta previa
painful: placental abruption
Which direction does a baby normally come out
ie which way is it facing
facing down
so occiput anterior
Bishop’s score for induction based on
position consistence effacement dilation fetal station
ACE inhibitors in pregnancy
nope
renal tissues in baby, oligohydramnios and neonatal renal failure
Gestational HTN definition
HTN w/o proteinuria after 20 wk
These two drugs may reduce risk of pre-eclampsia occuring
Ca2+ supplementation
ASA
Nonstress test
monitors baby movements
tracks fetal heart tones to make sure they accelerate when the baby kicks
Bishop’s score for induction based on
position consistence effacement dilation fetal station
