Complicated Pregnancy Flashcards
What is abruptio placentae
- Premature separation of the placenta from the uterine wall
- Presents as heavy painful vaginal bleeding in the 3rd trimester
tx for breech presentation
external cephalic version
(@ or near term)
tx for cord prolapse
- Immediate c-section
- manual elevation of the presenting fetal part
- repositioning of the mother to knee chest position
what is dystocia
Failure of cervical dilation and fetal descent (difficult labor)
3 causes of dystocia
- Small pelvis
- Poor contractions
- Tx: IV Pitocin
- Macrosomia
tx for dystocia
Forceps, vacuum, C-section
tx for shoulder dystocia
- McRoberts maneuver (1’st line) – increase pelvic opening by elevating the maternal thighs against the abdomen
- Woods corkscrew maneuver: 180 shoulder rotation; if no success then emergent C section
What is the turtle sign and what does it indicate
retraction of the delivered head against the maternal perineum
= shoulder dystocia
Medications used for induced abortions
< 9 wks: Mifepristone –> Misoprostal (1-3d later)
< 7 weeks: Methotrexate–> Misoprostal (3-7d later)
4-12wks: D&C
>12wks: dilation and evacuation
What is the difference b/w mild and severe pre-eclampsia?
- Mild
- BP >140/90
- > +1 proteinuria
- Severe
- BP >160/110
- > +3 proteinuria
- thrombocytopenia
- oliguria
- HELLP
Tx for MILD pre-eclampsia
- deliver at 37 wks
- if < 34wks:
- BP + dipstick weekly, bedrest
- Steroids to mature lungs
Tx for severe pre-eclampsia
(>160/110, > 3+ protein)
- PROMPT DELIVERY
- Hospitalize–> give MAG
- _Hydralazine*_, labetolol, Nifedipine
Tx for eclampsia
ABCDs
Mag (for seizures)
Delivery (once stabilized)
Hydralazine, labetolol
what is the TOC for moderate/severe pre-existing HTN
(meds if BP >150/100)
Methyldopa
(labetolol, hydralazine, Nifedipine)
PAINLESS vaginal bleeding in 3rd trimester
placenta previa
tx for placenta previa (painless vag bleed 3rd tri)
- Hospitalize. bed rest
- Mag (inhibits uterine contraction/preterm labor)
- Steroids (if 24-34wks, lung maturity)
- Deliver when stable (if >36w, blood loss >500mL)- Vag or CD
PAINFUL vag bleed (dark red), continuous
Abruptio placentae
Tx for Abruptio placentae
Hospitalize
IMMEDIATE C-SECTION
may lead to DIC
what is a complication of Abruptio placentae
DIC (10%)
MCC Abruptio placentae?
(9 causes)
- MCC- Maternal HTN
- smoking, ETOH, cocaine
- folate deficiency
- high parity
- increased age
- trauma
- chorioamnionitis
What is Vasa previa
tx?
- fetal vessels travers the fetal membranes over the cervical os
- ROM–> PAINLESS vag bleed
- TX= immediate CD
Screening for GDM: BS > ____ after 50g GTT
> 140
What is a positive 3hr GTT
fasting >95
1hr >180
2hr >155
3hr >140
TOC for GDM
insulin (doesn’t cross the placenta)- indications= fasting >105, pp>120
Glyburide, metformin
INDUCE AT 38WKS IF UNCONTROLLED/MACROSOMIA
Difference b/w complete and partial molar pregnancies
complete= egg w/o DNA + 1-2 sperm= all paternal chrom, 46XX
partial= egg + 2 sperm
“SNOWSTORM” appearance on ultrasound
molar preg
tx for molar preg if METS
methotrexate
which Coombs test do you use to screen forRh type/alloimmunizations
INDIRECT coombs
1st line tx for morning sickness and hyperemesis gravidarum
Pyridoxine (vitB6) + Doxylamine
PP hemorrhage= >____ml if vaginal or >____ if CD
>500ml vaginal
>1000ml CD
MCC PP hemorrhage
uterine atony
tx for PP hemorrhage
- _Bimanual uterine massage***_
- only if uterus soft and boggy: oxytocin, Methylergonovine, Carboprost, Tromethamine, Misoprostol
what 2 tests are used for PROM
- Nitrazine paper test (turns blue if pH >6.5= PROM)
- Fern test (amniotic fluid fern pattern
- ultrasound
tx for preterm labor
- steroids (betamethasone)
- Tocolytics (prevent uterine contraction)
- Indomethacin (24-32wks)
- Nifedapine (32-34wks or 2nd line 24-32wks)
- Mag sulfate (must be admitted, not used w/ nifedipine)
- Terbutaline (2nd line 32-34wks)
antibiotic prophylaxis for GBS?
Ampicillin –> PO amox + azithro
PRN allergic= Cephazolin–> PO cephalexin + azithro
Dystocia:
What are the 3 categories of abnormal labor progression?
- Power
- Passenger
- Passage
Two treatment options for shoulder dystocia
1st line= McRoberts maneuver
Wood “Corkscrew” maneuver
How to induce labor
- unfavorable cervix= Cervidil (prostaglandin gel on cervix)
- Pitocin
- Amniotomy (rupturing membranes w/ hook)
