Chorionic Villus Sampling(CVS)

10-13 weeks diagnostics for fetal abnormalities

screens for Nerol Tube Defect at 16-18 weeks

HCG, AFP, Estriol ,Inhibin A screening

Purpose of doppler ultrasound

determine maternal-fetal blood flow

Abdominal Ultrasound to visualize fetus physically and physiologically

contraction Stress Test

at least 3 contractions in 10 min. lasting 35 seconds-CST

Percutaneous Umbilical Blood Sampling

preterm labor, umbilical cord laceration risk

What is the purpose of an standard ultrasound?

Locate a figure of a fetus or find placental location

Chorionic Villus Sampling(CVS)
low risk for spontaneous abortion or limb loss if < 9 weeks
10-13 weeks diagnostics for fetal abnormalities
empty bladder
Full bowel
3
Multiple Marker Results
Low AFP : cardiac defect
High AFP: Downs Risk
Noninvasive lab
High AFP: NEURO Tube Defect
4
Maternal Serum AFP
High AFP results-Downs
low results AFP -NTD
screens for Nerol Tube Defect at 16-18 weeks
urine sample
5
Amniocentesis
non-invasive
empty bladder after 20 weeks
10 weeks; sterile needle aspiration into amniotic fluid
full bladder in 3rd trimester
6
Quad Marker
blood sample at 10 weeks
Multiple Permanent Marker
urine sample at 16-18 weeks
HCG, AFP, Estriol ,Inhibin A screening
7
Purpose of doppler ultrasound
assess fetal position
determine maternal-fetal blood flow
assess fundal height
invasive diagnostic
8

12
contraction Stress Test
standardized
non-invasive
at least 3 contractions in 10 min. lasting 35 seconds-CST
kidney-stimulated contraction test or tocolytic stimulants
13
Percutaneous Umbilical Blood Sampling
preterm labor, umbilical cord laceration risk
Maternal blood sampling
clean procedure
no complications
14
What is the purpose of an standard ultrasound?
Locate a figure of a fetus or find placental location
confirm pulmonary blood flow
diagnose chromosomal defects
assess cranial abnormalities
15
Non-Stress Test
nonreactive NST best results
reports fetal heart rate accelerations up 15 beats/15 sec. 2x in 20 minutes
FHR decelerations
1st trimester procedure for GDM
