Diagnostic test in high-risk preg./prenatal det. Of fetal well being

1. Ultrasound-is a diagnostic technique which uses high-frequency soundwaves to create an image of the internal organs. A screening ultrasound is sometimes done during the course of a pregnancy to monitor normal fetal growth and verify the due date.

12

Page 13: High Risk Pregnancy

PURPOSESIn the first trimester: to establish the dates of a

pregnancy to determine the number of fetuses

and identify placental structures to diagnose an ectopic pregnancy

or miscarriage to examine the uterus and other

pelvic anatomy to detect fetal abnormalities

13

Page 14: High Risk Pregnancy

Mid-trimester: (sometimes called the 18 to 20 week scan)

to confirm pregnancy dates to determine the number of fetuses

and examine the placental structures to assist in prenatal tests such as an

amniocentesis to examine the fetal anatomy for

presence of abnormalities to check the amount of amniotic fluid to examine blood flow patterns

14

Page 15: High Risk Pregnancy

to observe fetal behavior and activity

to examine the placenta to measure the length of the cervix to monitor fetal growth

15

Page 16: High Risk Pregnancy

Third trimester: to monitor fetal growth to check the amount of amniotic fluid as part of other testing such as the

biophysical profile to determine the position of a fetus to assess the placenta

16

Page 17: High Risk Pregnancy

17

NON – STRESS TEST Tocodynamometer records fetal movements and

Doppler ultrasound measures fetal heart rate to assess fetal well-being after 28 weeks.

Nonstress test is basically performed to evaluate on how the baby is doing inside. How often you need the test will depend on your doctor; it can be every week or more often till the baby is born.

Page 18: High Risk Pregnancy

• The test result is considered to be normal or reactive if baby's heart beats faster on two separate occasions during the 20 minute span.

• If baby is resting the result will most likely be non-reactive. However if results persist to be non-reactive even after one hour, it doesn't necessarily mean something is wrong with the baby.

18

Page 19: High Risk Pregnancy

• Results may also be non-reactive due to baby's age; babies below week 32 have not hit the required maturity for reactivity. • The test time may be extended or the mother may have to go for more comprehensive tests like biophysical profile• If your doctor is absolutely sure that baby is not thriving inside, the labor may be induced

Page 21: High Risk Pregnancy

Who needs the nonstress test..• Women with preexisting medical conditions such as

diabetes• Women with pregnancy-induced medical conditions such

as hypertension• Baby is less active than normal• Baby is small for its age• Amniotic fluid is either too much or too little

21

Page 22: High Risk Pregnancy

• Women who have previously lost their babies in the second half of their pregnancies

• Women with pregnancies continuing after week 40 to basically check on the well- being of baby

22

Page 23: High Risk Pregnancy

INTERPRETATION

A. Normal:Reactive- increased FHT (acceleration) greater than 16 bpm /secor more in 10 to 20 min. period w/ fetal movement

B. Abnormal: Non reactive- No FHR ACCELERATION WITH FETAL MOVEMENT

23

Page 24: High Risk Pregnancy

INTERPRETATION

A. Normal : high –risk pregnancy continue

b. Abnormal result: mother needs another test, maybe biophysical profile

24

Page 25: High Risk Pregnancy

OXYTOCIN CHALLENGE TEST(OTC) OR CONTRACTION STRESS TEST (CST)

CST is based on the observation that during contractions, blood flow to the placenta lessens temporarily. An evaluation is done on how the fetus handles this stress. (utero-placental well being)

25

Page 26: High Risk Pregnancy

Interpretation:

a. normal: negative – No late decelerations of FHR w/ each of 3 contractions during a 10 minute interval

b. Abnormal: positive – with late decelerations of FHR with 3 contractions in 10 minutes.

26

Page 27: High Risk Pregnancy

E. BIOPHYSICAL PROFILE

A scoring combining ultrasound assessment of: a. Fetal breathing

b. Fetal movement c. Fetal tone d. Reactivity of the heart rate e. Amniotic fluid volume BPP could

be used to predict fetal well-being in high-risk pregnancy

27

Page 28: High Risk Pregnancy

Purpose

The purpose of the BPP is to assess fetal well-being. It is a tool used near or at term by clinicians to assess the potential risk of fetal compromise or demise due to fetal hypoxia or acidosis. Intervention such as maternal hospitalization, or delivery may follow a BPP score of four or below

28

Greater than or = to 1 episode of 30 sec. or more of fetal breathing movement in 30 min3 or more discreet movements of the body or any limb in 30 minutes

Absence of 30 secs. Or longer of fb movement in 30 min

2 or lesser discreet movement of body or a limb in full extension or absent fetal movementEither slow extension with return to partial flexion or movement of limb in full extension or absent fetal movement

29

Page 30: High Risk Pregnancy

EVALUATION OF FETAL EVALUATION OF FETAL WELL-BEINGWELL-BEING

Surveillance of fetal well-being is based on 5 categories:

• Non-stress test (NST)• Amniotic fluid index• Fetal breathing movements• Fetal tone• Reactive heart rate

Note: each category carries a score of 2 and the summative number interpreted by the physician. A score of 8-10 is reassuring.

•Maternal serum screens for open neural tube defects. Alpha-fetoprotein is a glycoprotein produced by fetal yolk sac, GIT and liver.

•Test is done between 16-18 weeks gestation.

•High levels indicate neural tube defects and anencephaly and spinal bifida; also associated with congenital nephrosis, esophageal atresia, fetal demise.

Page 36: High Risk Pregnancy

EVALUATION OF FETAL EVALUATION OF FETAL WELL-BEINGWELL-BEING

• Uses amniotic fluid to ascertain fetal lung maturity through measurements of presence and amounts of lung surfactants Lecithin and Spingomyelin.

• At 35-36 weeks, ratio is 2:1 indicative of mature levels.

• May be done in laboratory or by “SHAKE” tests.

COMPLICATION OF PREGNANCY Pre-gestational conditions: Pregnancy induced hypertension (PIH)

is a condition of high blood pressure (HYPERTENSION) during pregnancy. Your blood pressure goes up, you retain water (EDEMA), and protein(PROTEINURIA) is found in your urine. It is also called toxemia or preeclampsia. The exact cause of PIH is unknown.

FIGURE 15–4 To elicit clonus, with the knee flexed and the leg supported, sharply dorsiflex the foot, hold it momentarily, and then release it. Normally

the foot returns to its usual position of plantar flexion. Clonus is present if the foot “jerks” or taps against the examiner’s hand. If so, the number of taps or

beats of clonus is recorded.

B. DIABETES MELLITUS

A chronic, metabolic disorder characterized by a deficiency in insulin production by islets of Langerhans resulting in improper metabolic interaction of carbohydrates, fats. Protein and insulin

GDM] is usually diagnosed around 24

to 28 weeks of pregnancy.50

Complication of dm in mother Preeclampsia Urinary tract infections Future diabetes Dystocia Maternal mortality Diabetic retinophaty Diabetic nephropathy

53

Page 54: High Risk Pregnancy

Fetus/ infant Excess growth. Extra glucose will

cross the placenta, which triggers your baby's pancreas to make extra insulin. This can cause your baby to grow too large (macrosomia). Very large babies are more likely to become wedged in the birth canal, sustain birth injuries or require a C-section birth.

54

Page 55: High Risk Pregnancy

Low blood sugar (hypoglycemia). Sometimes babies of mothers with gestational diabetes develop low blood sugar (hypoglycemia) shortly after birth because their own insulin production is high. Severe episodes of this problem may provoke seizures in the baby. Prompt feedings and sometimes an intravenous glucose solution can return the baby's blood sugar level to normal

55

Page 56: High Risk Pregnancy

Respiratory distress syndrome. If your baby is delivered early, respiratory distress syndrome — a condition that makes breathing difficult — is possible. Babies born to women with gestational diabetes have more breathing problems than do those born to women without the problem, even at the same gestational age. Babies who have respiratory distress syndrome might need help breathing until their lungs become stronger. 56

Page 57: High Risk Pregnancy

Jaundice. This yellowish discoloration of the skin and the whites of the eyes may occur if a baby's liver isn't mature enough to break down a substance called bilirubin, which normally forms when the body recycles old or damaged red blood cells. Although jaundice usually isn't a cause for concern, careful monitoring is important.

Type 2 diabetes later in life. Babies of mothers who have gestational diabetes have a higher risk of developing obesity and type 2 diabetes later in life.

57

Page 58: High Risk Pregnancy

Developmental problems. If you have gestational diabetes, your child may have an increased risk of problems with motor skill development, such as walking, jumping, or other activities that require balance and coordination. An increased risk of attention problems or hyperactivity disorders also is a concern.

a. Exhibits a decrease in both systolic and diastolic blood pressure

b. Experiences no seizures

c. States that she feels more relaxed and calm

d. Urinates more frequently, resulting in a decrease in pathologic edema
