How do we test for Rh incompatibility?
Indirect Coombs - detects antibodies in Mom against Rh - fetus
Direct Coombs - detects antibodies against Rh+, performed with PUBS
First Trimester Ultrasound
Ask mom to drink 3-4 glasses of water and to not urinate
of fetuses
presence of fetal cardiac movement/rhythm
uterine abnormalities
gestational age
Chorionic Villi Sampling
Performed at 10-12 weeks gestation
Evaluates DNA, bleeding, infection or miscarriage risk
Biochemical analysis
Tay Sachs
1st Trimester
Rh Incompatibility
AKA isoimmunization
When mom is Rh- and baby is Rh+, it has inherited this gene from the Dad, mom will create antibodies against the fetus, typically the first pregnancy is not affected, but antibodies grow with future pregnancies
If not treated, then fetus can become anemic or jaundiced with immature RBC production
No impact if mom is + and baby is -
Complication: Hydrops Fetalis
Non-Stress Test
Evaluates fetal oxygenation
Reactive=normal; 2 accels (15x15) in 10-20min
If nonreactive, then will need biophysical profile (in utero) and apgar (out of utero)
Early Decelerations: What are they? Interventions?
Before peak of contraction
Associated with head compression resulting in vagus stimulation and slowing of HR
NO interventions, baby is coming
Variable Decelerations: What are they? Interventions?
Resemble U, V, W
Associated with cord compression cutting O2 at random times
Nursing Interventions:
- change maternal position
- drink juice
- stop pitocin
- administer O2
- vaginal exam for cord prolapse
- Severe - amniocentesis
What are normal contraction rates?
Every 3-5 minutes
Last 45-90 seconds
Uterus is soft and relaxed between contractions
Variable Fetal Heart Tones
Normal is 6 to 25 beats
IF <5, fetus may be sleeping
VEAL CHOP
Variable Cord Compression
Early Head Compression
Accelerations OK
Late Placenta issue
Abortion: Types, S/Sx
Elective or spontaneous
No fetal viability before 20weeks
S/sx:
Uterine Cramping
Vaginal Bleeding - bright red
Pelvic Pressure
Backache
Ecotopic Pregnancy: What it is, S/Sx, Treatment
Fertilized ovum outside uterus in fallopian tube
S/Sx:
UNILATERAL, sharp abdominal pain
Normal pregnancy symptoms
positive pregnancy test
If suspected you can perform gentile uterine palpitation
Treatment:
NPO if surgery (sometimes sent home on methotrexate)
VS
Monitor for signs of bleeding, including Cullen Sign
Type and Crossmatch blood
Molar Pregnancy
Degenerative placenta, fertilized egg without embryo but incorrect chromosomes
Characterized by grape-like clusters
S/Sx:
Preeclampsia prior to 20 weeks
NO FHT or skeleton
hCG continues to rise when it should decline
Abnormal uterine bleeding
Uterus larger than dates
Anemia from blood loss
Excessive vomiting
Abdominal cramping
Treatment:
- Prep for D&C
- Monitor hCG levels for 1-year: monthly for first 6-months then every 2 months for 6-months
-No pregnancy for 12-months as pregnancy can mask symptoms of chorioncarcinoma
- Possible prophylactic chemo
Gestational Diabetes: What’s happening, risks?
Hormonal changes increase maternal insulin resistance to ensure baby has enough glucose
Insulin resistance due to placental hormones (insulinase and cortisol)
Moms are more prone to preeclampsia, hemorrhage, infection, hydroaminos and macofetus
Macroscopic Fetus
> 4000g
May cause prolonged 2nd labor stage, head injury or shoulder dystocia
If C-section, then baby may have respiratory distress due to absence of vaginal squeeze
Baby may experience hypoglycemia - if >5000g may last for 1 week
Very large babies need to be vented or receive supplemental O2
Respiratory Distress in GDM
Caused by decreased surfactant
Increased risk ventilation or supplemental oxygen
In GDM, what happens in 3rd stage of labor to mom?
Insulin requirements drop substantially in first 24-hours, recommended to discontinue long acting insulin before delivery.
Mom recommended to breast feed for better glucose control
Hospital Care:
5% glucose infusion
Monitor ketones
monitor hemorrhage
Neonatal Hyperproliferation of Pancreas
Enlarged pancreas due to high maternal glucose which causes increased insulin needs in fetus, but when umbilical cord is cut then no constant source of glucose but pancreas continues to put out high levels of insulin
Resolves in 4hrs, but if baby is >5000g then it can take a week
Fetal Lung Maturity
Based on LS - lecithin:sphingomyelin ratio
Accounts for AFV changes
Tested via amniocentesis before induction
Considered mature if ratio >2.2 or if PG (phosphatidyglycerol) is present in surfactant past 36 weeks
Preeclampsia: S/Sx, medication, complications
HTN after 20-weeks gestation with no history of HTN
S/Sx: (acronym = pre)
Proteinuria
Rise in BP (>140/90 on 2 occasions) or >160/90 on shorter occasions
Edema
Rapid weight gain >2lbs/week
Decrease UOP
Hyperrefelxia 2+ Clonus
Medication:
Labetaol
Hydrazine hydrochloride
Complications: eclapsia, HELLP syndrome, DIC
Eclampsia: S/Sx, treatment

ABSENT DTR
Decrease RR
Diaphoresis/flushing
Warmth
EKG Changes
Decreased UOP but increase in mag level
Antidote: calcium gluconate
Fetal Movement
Evaluate fetal oxygenation
Fetal Kick Counts
Fetal movement evaluates fetal oxygenation
Emergency: No kick counts of <10 in 12 hours
Contraction Stress Test
Evaluates fetal oxygenation and ability to tolerate contractions w/o placental insufficiency
negative contraction test is desired
positive indicates late DHR decelerations
Biophysical Profile
IN UTERO
Looks for signs of distress
Assessment of fetal well-being based on 5 factors
1) fetal breathing movement
2) Fetal movement
3) fetal tone
4) Reactivity of FHR/ reactive NST
5) AFV
Score of 2 or 0 can be assigned, fetal well-being 8-10 is healthy
Amniocentesis: What is it, when is it performed, what does it determine, complications
Performed at 20 weeks
Anatomy or DNA for high-risk moms (>35 or MSAFP elevated or decreased)
Determines:
karotype
biochemical analysis
AFV
Fetal lung maturity
Fetal well-being
Complications: infection, miscarriage, bleeding
Fetal heart Echo

Stage 1
Early/latent 0-5cm
Active 6-10cm with cervical dilation
Stage 2 labor
Pushing and birth of neonate
Ends with delivery of baby’s feet
Stage 3 Labor
Delivery of placenta
Must not exceed 20 minutes due to dilated uterine veins and increased hemorrhage risk
