OBGYN Flashcards
adenomyosis
cyclic pelvic pain with menstruation, heavy bleeding
typically in parous 40+ woman
- PE; soft, boggy, uniformly enlarged uterus
breast lump found on PE, now what?
> 30- mammaography +/- US
<30 - US+/- mammography
epidural anesthesia AE
- ) leakage of CSF into dura- symptoms: postural headache
- ) total spinal/high spinal: when anesthesia ascends to head and depresses brainstem- causes bradycardia, hypotension, and respiratory difficulty
- ) hypotension caused by sympathetic Ns involvement leads to venous pooling, decreased preload, decreased contractility
stroke/other thrombotic event + recurrent pregnancy loss
Antiphospholipid syndrome
for labor to be arrested, what needs to be met?
- > 4 hrs of no cervical change with ADEQUATE contractions
- >6 hrs of no cervical change WITHOUT adequate contractions
treatment for arrested labor vs protraction of labor?
arrest- c section
protraction- oxytocin
whats adequate contraction
> 200 MVUs
how do you work up decreased fetal movement in a fetus WITH heart beat
- do a non-stress test for >40min to assess if the fetus is just in regular sleep cycle or if something is wrong. Reactive= 2+ acc and is normal and can rule out fetal acidemia
- if nonreactive, you can do either a BPP (biophysical profile) or CST (contraction stress test). dont do CST if there are contraindications to labor, like placental previa or prior mymectomy!
what is BPP
a test to assess fetal oxygenation, a score less than 8/10 suggests placental dysfunction. Each category gets either 0 or 2
- NST
- amniotic volume: single pocket >/=2 cm or index>5
- fetal movement>/=3
- > /=1 flex or ex
- > /=1 breathing in 30 sec
in a fetus without doppler heart beat whats next?
transabdominal US to find heart beat. if not there, it confirms fetal demise.
define pre-ecclampsia
BP > 140/90 on 2 occasion with proteinuria prot:creat>0.3 at greater than 20 wk
define pre-ecclampsia w severe features
either severe htt > 160/110
creat>1.1, elevated transaminases, plt <100,000, headache or visual changes
pt w nonviable fetus in breech position
- do vaginal delivery not csection
how can you figure out cause of FGR?
- if symmetric (aka head and body are smaller by same amt) its most likely a 1st tri prob such as chromosomal abnormality
- if asymmetric (aka head and body smaller by diff amounts) most likely a 2nd/3rd tri prob like htt
what is intertrigo
red beefy plaques in skin folds usually due to candida
when to stop PAP
age 65 with no history of CIN 2+ and 3 consecutive neg paps
how can you tell normal pregnancy vomitting from hyperemesis gravidum
get a urine ketones
how do you treat a pt with confirmed chlamydia by NAAT
just azithromycin or doxy
what are causes of maternal virilization in pregnancy
- placental aromatase def
- luteoma - bilat solid mass on ovaries
- theca lutein cyst - bilat cystic (low risk of fetal vir)
- sertoli leydig tumor - solid unilat ovarian mass
lichen sclerosis on genitals treatment
high dose corticosteroid ointment, clobetasol
what do you do if uterus prolapses during placental traction
- 2 large bore IVs with crystalline fluids and blood products
- replace the uterus, LEAVE THE PLACENTA ON THE UTERUS to prevent massive hemorrhage
ovarian cyst with hyperechoic calcifications?
dermoid
loss of fetal station (fetus goes from station 0 to -3)
pathognomonic for uterine rupture
what is tachysystole?
increased rate of uterine contractions, More than 5 in 10 mins, for over 30 mins
what is the pathophys of gestational diabetes mellitus?
increased insulin resistance because of HPL to help shunt more glucose to fetus. If the insulin resistance overpowers the pancreatic B cell insulin production, this leads to GDM

(not mastitis, not abscess).
peau dorange
physiologic changes during pregnancy for mom?
- hypercoag. state: increase in fibrinogen, decrease prot C/s
- gestation thrombocytopenia
- dilutional anemia
- renal: increased GFR and RBF causes decreased BUN and creat, BM more permeable so more urine protein
variable deceleration
- “Intermittent”nadir does not correspond to contraction peak >50%
- “recurrent” nadir does correspond to peak, BUT are sharper and steeper, must be <15 sec from onset to nadir
causes: cord compression, cord prolapse,oligohydramnios
early contraction
- nadir occurs at same time as contraction peak, must be >30 sec from onset to nadir
causes: fetal head compression, or can be normal
late contraction
nadir occurs after contraction; must be >30 sec from onset to nadir
causes: placental insufficiency
what is the treatment for variable decelerations?
- if intermittent, risk of fetal acidemia is low, and treatment not needed
- if “recurrent” risk of fetal acidemia is greater, and treatment needed. 1st line is maternal repositioning. 2nd line amnioinfusion
how to manage endometriosis
- NSAIDs, hormonal contraceptives
- if these fail do a laparoscopy
what is a main side effect of endometriosis
infertility
how do you manage pre-term labor?
if <34 wks try nifedipine or indomethacin which are tocolytics
>34 wks, deliver. if in breech or contraindication to labor do c-section

what are the different ABO incompatibility
if a mom is O, she most likely has ab preformed to A and B which can cross the placenta. fetus might experience mild hemolytic disease
if mom is A or B, the antigens on the RBC are too large IgM pentamers and will not cross the placenta
