Relative contraindications to the CST generally include conditions that also are contraindications to labor or vaginal delivery Contraction stress fetal heart rate monitoring at pre- term ffetal ages. Most growth-restricted fetuses can be adequately evaluated with serial ultrasonography every 3—4 weeks; ultrasonographic assessment of growth should not be performed more frequently than every 2 weeks because the inherent error associated with ultrasonographic mea- surements can preclude an accurate assessment of inter- val growth 70— This type of monitoring is more accurate than external monitoring.

If delivery is not undertaken, follow-up amniotic fluid volume measurements, NSTs, and fetal growth assess- ments are indicated. Umbilical artery Doppler velocimetry has not been shown to be predic- tive of outcomes in fetuses without growth restriction.

Absence of end diastolic frequencies in umbilical artery: Simultaneous assess- ment of blood flow velocity waveforms in uteroplacental vessels, the umbilical artery, the fetal aorta and the fetal common nonitoria artery. Screening for fetal well-being in a high-risk pregnant population comparing the nonstress test with umbilical artery Doppler velocim- etry: An abnormal heart rate or abnormal pattern may indicate that the fetus is not getting enough oxygen or having other problems.

These guidelines should not be construed as dictating an exclusive course of treatment or procedure. Antepartum fetal surveillance techniques are routinely used to assess the risk of fetal death in pregnancies complicated by preexisting maternal conditions eg, diabetes mellitus as well as those in which complications have developed eg, fetal growth restriction.

III Opinions of respected authorities, based on clinical experience, descriptive studies, or reports of expert committees.

In one small randomized study, it took less time to obtain a reactive NST when patients were placed in the semi-Fowler posi- tion The relation- ship of the nonstress test to gestational age.

Doppler flow velocity waveform analysis in ffetal risk pregnancies: Adog is the recommended management of an abnormal antepartum fetal test result? The modified BPP combines the NST, as a short-term indicator of fetal acid—base status, with an amniotic fluid volume assessment, as an indicator of long-term placental function Although the degree of hypoxemia and acidemia at which various indices of fetal well-being become abnor- mal is not known with precision, it can be estimated based on data from published studies.

In RCTs, how- ever, this increased surveillance did not result in a higher rate of intervention 12, 86, Currently, there is no evidence that umbilical artery Doppler velocimetry provides infor- mation about fetal well-being in the fetus with normal growth.

Thus, a reasonable correlation between certain measur- able aspects of FHR and behavior and evidence of fetal metabolic compromise can be fetall.

In some cases of severe fetal growth restric- tion, diastolic flow is absent or even reversed. Umbilical artery blood flow characteristics in normal and growth-retarded fetuses. A definitive evaluation of antepartum fetal.

Based on expert opinion, in monitorka setting of otherwise uncomplicated isolated and persistent oligohydram. Thus, regardless of the fetal movement approach used, in the absence of a reassuring count, further fetal assessment is recommended.

Specifically, the umbilical flow velocity wave- form of normally growing fetuses is characterized by high-velocity diastolic flow, whereas in growth-restricted fetuses, there is decreased umbilical artery diastolic flow 42— The following recommendations are based pri- marily on consensus and expert opinion Level C: Such an approach takes advantage of the high negative predictive value gener- ally exhibited by all commonly used antepartum tests and minimizes the potential for unnecessary delivery based on a single false-positive ie, false-abnormal test result.
