Description of Antenatal Assessment components, tests and interpretation of Fetal wellbeing

2. Objective is to avoid
fetal death.
• Aims

3. Tests must provide information superior
to that of clinical evaluation .
Test results should be helpful in
management to improve perinatal
outcome
Benefits of tests must outweigh the
potential risks and the costs

4. • METHODS:
• 1.Clinical 2. Biophysical 3.Biochemical

5. • BIOPHYSICAL:

7. 1.Fetal movement count
1.Cardif “count 10” formula:

8. • 2.Daily fetal movement count (DFMC):

9. • Loss of fetal movements-is

10. 2.Non-stress test (NST):

12. 3.Vibroacoustic stimulation (VAS)

13. 4.Fetal Biophysical Profile (BPP)—

15. An abnormal score
of 4 or less is
associated with
fetal acidemia.
Abnormal BPP is
associated with
high risks of
stillbirth and
perinatal mortality.

16. 5.Fetal Cardiotocography (CTG):

17. 6.Ultrasonography:
• AC is the single measurement which best reflects fetal nutrition.

18. 7.Amniotic fluid volume (AFV):

19. 8.Doppler UltrasoundVelocimetry:
(umbilical artery)
• In a normal pregnancy the S/D ratio, PI and RI decreases as the
gestational age advances.

20. • Venous Doppler (DuctusVenosus, UmbilicalVein)

24. 9.Contraction stress test (CST)

25. • Pulmonary maturity:
• 2.Assessment of severity of Rh–isoimmunization
