The biophysical profile discussed in the ACOG bulletin is a nonstress test plus four observations made by real-time ultrasonography. The nonstress test of the neurologically healthy preterm fetus is frequently nonreactive-from 24 to 28 weeks of gestation, up to 50 percent of nonstress tests may not be reactive, and from 28 to 32 weeks of gestation, 15 percent of nonstress tests are not reactive. The nonreactive stress test lacks sufficient fetal heart rate accelerations over a 40-minute period. Most commonly, the nonstress test is considered reactive, or normal, if there are two or more fetal heart rate accelerations within a 20-minute period, with or without fetal movement discernible by the woman, according to ACOG. Various definitions of reactivity have been used. Results of nonstress tests are classified as reactive or nonreactive. Loss of reactivity is commonly associated with a fetal sleep cycle but may result from any cause of central nervous system depression, including fetal acidosis. Heart rate reactivity is believed to be a good indicator of normal fetal autonomic function. In the nonstress test, the heart rate of the fetus that is not acidotic or neurologically depressed will temporarily accelerate with fetal movement. History of extensive uterine surgery or classic cesarean delivery. Preterm labor or certain patients at high risk of preterm labor. According to ACOG, these conditions include the following: Relative contraindications to the contraction stress test usually include conditions that are associated with an increased risk of preterm labor and delivery, uterine rupture or uterine bleeding. Fewer than three contractions in 10 minutes or a tracing that is not interpretable. Fetal heart rate decelerations that occur in the presence of contractions that are more frequent than every two minutes or last longer than 90 seconds. Intermittent late decelerations or significant variable decelerations.Įquivocal- hyperstimulatory. Late decelerations following 50 percent or more of contractions (even if the contraction frequency is fewer than three in 10 minutes).Įquivocal- suspicious. No late or significant variable decelerations. The results of the contraction stress test are categorized in the ACOG bulletin as follows: The contraction stress test is interpreted by the presence or absence of late fetal heart rate decelerations, which are defined as decelerations that reach their nadir after the peak of the contraction and that usually persist beyond the end of the contraction. Uterine contractions also may provoke or accentuate a pattern of variable decelerations caused by fetal umbilical cord compression, which in some cases is associated with oligohydramnios.

In the fetus with suboptimal oxygenation, the resulting intermittent worsening in oxygenation will, in turn, lead to the fetal heart rate pattern of late decelerations. It is believed that fetal oxygenation will be transiently worsened by uterine contractions. The contraction stress test is based on the response of the fetal heart rate to uterine contractions. The optimal number of movements and the ideal duration for counting movements have not been determined however, numerous protocols have been reported and appear to be acceptable.

The mother counts fetal “kicks” as a means of antepartum fetal surveillance. FETAL MOVEMENT ASSESSMENTįetal movement assessment occurs when the mother perceives a diminution in fetal movement. These include fetal movement assessment, nonstress test, contraction stress test, fetal biophysical profile, modified biophysical profile and umbilical artery Doppler velocimetry. Several techniques for antepartum fetal surveillance currently in use are discussed in the ACOG bulletin. Techniques of Antepartum Fetal Surveillance
