, there are several maternal- and pregnancy-related indications;3
Maternal
conditions
Pregnancy-Related or Fetal Conditions
Antiphospholipid
syndrome
Pregnancy-induced hypertensive disorders
Cyanotic heart disease
Decreased fetal
movementSystemic lupus erythematosusOligohydramnios and polyhydramniosChronic renal diseaseIntrauterine growth restrictionInsulin-related diabetes mellitusLate term or post-term pregnancyHypertensive disordersAlloimmunizationHyperthyroidismPrevious fetal demiseHemoglobinopathiesMultiple gestation
Slide4Nonstress test (nst
)

Slide5Nst
(continued)5
NST has
the highest false-positive rate and
the highest
risk for
a false-negative test
result among other monitoring tests.
Slide6Nst
(continued)6
Slide7Contraction stress test (CST)
7
CST measures the response of the fetal heart rate to the
stress of a uterine contraction.The result can be considered negative,
positive
,
equivocal
, or
unsatisfactory
.
Slide8Biophysical profile (bpp
)

Slide9BPP (continued)
9
Management based on
the BPP depends not only on the score itself but also on the gestational age of the fetus.
Irrespective of
the score
, more frequent BPP testing or consideration of delivery may
be warranted
when oligohydramnios is present.
Slide10Bpp

Modified BPP combines the use of an NST
and assessment of an amniotic fluid using the deepest vertical pocket sonographically or an amniotic fluid index (AFI).10
