OB GYN Flashcards
dx and treatment for hyperemesis gravidarum
dx: check bhcg and US to r/o molar. evaluate labs
tx: vit B6, doxylamine, promethazine
metoclopramide or ondansetron if severe
Non stress test
FHR- doppler
reactive: 2 accels >15 bmp >15 sex in 20 min
contraction stress test
FHR- doppler during mom contractions
pos: late devels >50% of the contractions
BPP
uses US
assess tone, breathing, movement, amniotic fluid vol, NST
umbilical artery doppler velocimetry used when what suspected
IUGR
DM tested when in pregnancy and how
24-28 weeks
- screen: 1 hr 50 g glucose challenge test
- confirm: oral 3 hr 100 g glucose tolerance test
most common cause of prolonged second stage of labor
fetal malposition
causes and dates of symmetric vs asymmetric fetal growth restriction
symmetric: 1st tri- chromosome abnl, infection
asymmetric: 2nd, 3rd tri- utero-placental abnl (HTN), malnutrition
how to determine whether to do misopristol or suction curettage for inevitable abortion
hemodynamically stable: misopristol
unstable: suction curretage
treatment for asx endometriosis
nothing, observe
lactation suppression managment
NSAIDs, ice packs, avoid nipple stimulation
does toxic shock syndrome include palms and soles?
yes
sudden pelvic pain with known ovarian mass should make you think of
ovarian torsion
braxton hicks contraction characteristics
mild irregular contractions
no cervical change
prognosis of erb palsy from shoulder dystocia
most spontaneously recover in 3 months
most effective way of preventing HIV vertical transmission
triple HAART therapy
when is c-section indicated over oxytocin for arrest of active labor
no cervical change >4 hrs + adequate contractions
no cervical change >6 hrs + inadequate contractions
what is this: normal internal female genitalia, external virilization, undetectable estrogen, high T
aromatase deficiency
how does CAH differ from aromatase deficiency
same normal internal, ambiguous external
but also electrolyte abnormalities- hyponatremia
McCune-Albright syndrome
cafe au lait spots
polyostotic fibrous dysplasia
autonomous endocrine function
precocious puberty
ovarian hyperthecosis
virilization in post-menopausal women
insulin resistance
classic vs nonclassic CAH
classic: newborn girl with ambiguous genitalia and adrenal insufficiency
nonclassic: late onset, androgen excess
21 alpha hydroxyase def characteristcis
increased: 17 hydroxy-progesterone, renin
decreased: K, cortisol
hypotension, virilization
11 beta hydroxylase def labs
decreased: aldosterone, K, renin, cortisol
hypertension, virilization
17 alpha hydrozylase characteristics
hypertension
XY: psuedo hermaphrodite
XX: lack secondary sex dev
decreased: K, cortisol
fetal demise diagnosis confirmed how
US
first step to determine preterm labor
transvaginal US- measure cervical length
treatment for preterm labor with short cervix in people with hx of preterm labor vs without hx
with hx: cerclage
without hx: vaginal progesterone- quiescence
when is quad screen done
15-22 weeks- but not diagnostic!
when is cell free DNA done?
> 10 weeks
maternal complications of abruptio placenta
DIC
hypotension
umbilical cord prolapse associated with
breech/malpresentation
abnl fetal heart rate tracing
