Endocervical length 
L:S ratio
PG
16
Q

What is fetal heart rate testing?

A

Non stress test used for at risk women such as diabetes, hypertension, decrease fetal movement, multiple gestation
Criteria: 2 accelerations of 15 bpm X 15 sec in 20 min

17
Q

What is a CST?

A

Contraction stress test
Determines if fetus will tolerate labor

Contraction:

  • 3 moderate contractions in 10 minutes to determine how fetus will respond
  • nipple stimulation: pill roll 2 min, stop 2 min then switch nipples
  • oxytocin: low levels
18
Q

What are the different gestational hypertensive disorders?

A

Preeclampsia
Eclampsia
Prevalence

19
Q

What is the etiology of gestational hypertensive disorders?

No cause
Some sort of immunological problem
Only cure is delivery

Hypertension
Proteinuria
After 20 weeks

A

Vasodpasm and organ perfusion
Intra vascular coagulation.
Increased permeability & capillary leakage

24
Q

What is mild preeclampsia?

A

Blood pressure >140/90
Proteinuria:
- 1+ to 2+ on urine sample
> 300 mcg in 24 hour urine

30/15 increase from baseline blood pressure

Seizures
Stroke
27
Q

What is treatment of mild eclampsia?

A

Goals: prevent progression to eclampsia
Limit activity
Environment
Delivery: induce when feel fetus in mature is 36 or 37 do amniocentesis to see if lungs mature

28
Q

What is treatment of severe eclampsia?

A

Hospitalization
Bed rest
Quiet environment, side rails up, restrict visitors, less stimulation, always auction & oxygen in room
Seizure precautions
Medications: bethamethazone to enhance fetal lung development
Delivery: by 34 weeks or if it worsens

29
Q

What are medications for preeclampsia?
