Question 1

What are the components of the BPP?

Answer 1

Nonstress test (NST) combined with 4 observations made with ultrasonography:

• fetal breathing
• movement
• tone
• amniotic fluid volume

Question 2

BPP scoring?

Answer 2

For each variable assessed with the BPP, a score of 0 (absent or abnormal) or 2 (present or normal) is given for a total of 10 possible points.

Question 3

BPP score of 6 or less in full term baby. Next step in management?

Answer 3

A score of 6 is considered equivocal, as fetal acidemia and hypoxemia cannot be excluded. At term gestation, a BPP of 6 or less supports prompt delivery.

Question 4

BPP score of 6 or less in preterm baby. Next step in management?

Answer 4

If preterm, a BPP of 6 or less supports repeat testing in 6 to 24 hours (as in the vignette), to minimize iatrogenic premature delivery of a healthy fetus.
