Placental site subinvolution - stony of uterus (give uterotonic)
51
Study this
52
Vasa preview only produces small amount of bleeding, why?
It’s from fetal blood, so it’s minimal. Enough to harm foetus though!

Asphyxia
69
Two types of FGR and the differentials in each
Symmetrical: head and body involved equally. Due to Chr issue or infection

74
Dx?
Active phase arrest
75
Dx
Protracted active phase of labour

Can the FetaL presentation change late on?
Yes! Must keep checking as it can change. Also, can do digital cervical exam to palpate presenting part in labour. If cannot palpate, do trans abdominal US. RECALL USMLE Q

They are the same. Roughly 32cm is 32 weeks
78
If foetus was dated using early first trimester US, is the chance of incorrect dating likely?
No

82
Can women with hep B or C breastfeed
Yes. Child needs to have had the Hep B ig and vx at birth though. And don’t breastfeed if there are visual cracks on nipples
83
Spontaneous abortion. Mx if stable, vs unstable or septic. In simple terms (mx sheets overcomplicates it)

There are few oxytocin receptors in these periods.
85
Recommendations to prevent listeria in pregnant women
Avoid raw meat, cheese stuff, deli, raw veg, wash hands if handle soil
86
Patient has cervical insufficiency. Mx? When do we not do this specific Mx..
Do rescue cerclage. If there is bulging amniotic sac, don’t do cerclage (risk of rupture)
87
How to calculate Montevideo units in a labour
Take difference between baseline uterine tone and peak contraction pressure (mmHg). Add these contraction pressures within 10 mins. 200-250 is good in active phase
