Stays the same (initially decreases then increases)

21
Q

Stays the same

22
Q

What drug to use for hyperthyroidism in the 1st trimester

23
Q

Adverse effect of PTU

Study These Flashcards
A

Liver toxicity/agranulocytosis (maternal)

24
Q

What drug to use for hyperthyroidism in the 2nd trimester?

25
Adverse effect of methimazole if used before the 2nd trimester
Aplasia cutis
26
What drug to use for hyperthyroidism in the third trimester?
Methimazole
27
What is the limiting dimension for delivery?
Ischial spines
28
What is the average bispinous diameter (ischial spines)?
10.5cm
29
What is the diagonal conjugate?
Distance from the sacral promontory to the symphysis pubis
30
Why do we measure the diagonal conjugate instead of the true/obstetric conjugate?
The true/obstetric conjugate cannot be reached | While the diagonal can be clinically assessed
31
Calculation for the obstetric conjugate
Diagonal conjugate - 1.5
32
A contracted obstetric conjugate =
<10.5cm
33
What is the measurement of the biparietal diameter at term?
9.3cm
34
What is the measurement of the femur length at term?
7.4cm
35
How can you use CRL to estimate weeks of gestation?
CRL (cm) + 6.5cm [ex 3.5cm + 6.5cm = 10 weeks]
36
Definition of Engagement
BPD passed the plane of the inlet, presenting part at ischial spines
37
Pelvic class that is round
Gynecoid
38
Pelvic class that is considered a "good delivery shape" and prognostically good
Gynecoid
39
Pelvic class that is an anterior-posterior egg shape
Anthropoid
40
Pelvic class that is associated with an increased OP delivery
Anthropoid (it is the only one w OP in the name and increased OP deliveries)
41
What population has increased anthropoid pelvises (OP deliveries) ?
African American (common blunted ischial spines and medium pubic arch)
42
Pelvic class that has an anterior-posterior diamond shape
Android
43
Pelvis shape that is the most limited in the transverse plane for flexed fetal head
Android
44
Pelvic class that is considered a "bad delivery shape"
Android; it has the least transverse diameter of outlet, also only prominent ischial spines and only narrow suprapubic arch
45
Pelvic class that has the shape of a flat oval
Platypelloid
46
Pelvic class that is persistent transverse (very wide)
Platypelloid
47
What population is a platypelloid pelvic increased in?
Korean women
