helps determine vascular
resistance in women with
Diabetes Mellitus and
Hypertension of pregnancy and
whether placental insufficiency
occurred

A

DOPPLER UMBILICAL VELOCIMETRY

A

OLIGOHYDRAMNIOS

33
Q

May be recorded as early as 11th
week of pregnancy

A

ELECTROCARDIOGRAPHY

34
Q

✔ NO harmful effects to the fetus
✔ To diagnose complications like
ectopic pregnancy

A

MAGNETIC RESONANCE IMAGING

35
Q

is produced by
the liver & present in amniotic fluid
and maternal serum.

A

Alpha-Fetoprotein

36
Q

requires only venipuncture of
the mother.

A

TRIPLE SCREENING (15-20
weeks)

37
Q

includes
INHIBIN determination

A

Quadruple screening

38
Q

biopsy & chromosomal analysis of
CV done at

A

10 to 12 weeks of
pregnancy.

39
Q

(transvaginal
aspiration of fluid from the
extraembryonic cavity) is an
alternative method to remove cells
for fetal analysis.

A

Culdocentesis

40
Q

✔ aspiration of AF from the
pregnant uterus for analysis.
✔ ambulatory procedure done at
14th to 16th week.
✔ ask woman to void (to reduce
size of bladder preventing
puncture).
✔ Place her on a supine
position, drape, place folded
towel under her right
buttock.
✔ attach FHR & contraction
monitors, take BP.
✔ explain that Ultrasound will
determine position of fetus

A

AMNIOCENTESIS

41
Q

if bubbly, the ratio is
mature.

A

SHAKE TEST

42
Q

✔ found also in surfactant and
pathways for these compounds
mature at 35 to 36 weeks; thus,
present only in mature lung
function
✔ more reliable than L/S ratio

A

PHOSPHATIDYLGLYCEROL &
DESATURATED PHOSPHATIDYLCHOLINE

43
Q

✔ done is blood incompatibility is
suspected
✔ sample must be free of blood to
avoid false-
positive results

A

BILIRUBIN DETERMINATION

44
Q

is done first to
ensure that the blood is fetal blood
before testing

A

Kleihauer-Betke test

45
Q

✔ visual inspection of the AF through
the cervix & membranes with an
amnio scope (fetoscope)
✔ to detect meconium staining ✔ risk of membrane rupture

A

AMNIOSCOPY

46
Q

✔ Fetus is visualized by a fetoscope (
an extremely narrow, hollow tube
inserted by amniocentesis
technique).
✔ a photograph may be taken of the
fetus.

A

FETOSCOPY

47
Q

✔ 5 parameters: fetal reactivity, fetal
breathing movements, fetal body
movement, fetal tone, amniotic fluid
volume.
✔ fetal heart & breathing record measures
short- term CNS function risk of
membrane rupture.
✔ Amniotic Fluid volume measures
long-term adequacy of placental function.
✔ more accurate in predicting fetal
well-being than any single assessment.
✔ called fetal APGAR
✔ done as often as daily if high risk
pregnancy

A

BIOPHYSICAL PROFILE

48
Q

RESULTS: BIOPHYSICAL PROFILE
fetus is doing
well

 = suspicious
 = denotes a fetus in jeopardy

A

8 to 10 score
6
4

49
Q

may be given to the mother if the
fetus is very active to sedate the fetus

A

Meperidine
