Clinical Trial Summary

Ultrasound Doppler studies are used during pregnancy to help manage pregnancies complicated by fetal growth restriction. The cerebroplacental ratio may predict adverse outcomes in low risk pregnancies. In a prospective study, the investigators will examine whether fetuses with an abnormal CPR at or near term are at increased risk for being delivered by cesarean,


Description:

This is a multicenter prospective study of low-risk nulliparous women who will be recruited if they are having an ultrasound at 36 weeks of estimated gestational age or greater. As part of the study, women will have umbilical and middle cerebral artery Doppler studies and the CPR will be calculated by dividing the middle cerebral artery PI by the umbilical artery PI. Providers caring for study subjects will be blinded to this result. Pregnancy outcomes in women with CPR values less than the 10th percentile for gestational age will be compared to those with CPR values above the 10th percentile. A secondary aim of the study is to analyze CPR as a continuous variable.

Outcome

Type Measure Description Time frame Safety issue
Primary Cesarean delivery Cesarean delivery rate for non reassuring fetal heart tracings From labor to delivery
Secondary Total cesarean section rate Cesarean delivery rate for other indications other than non reassuring fetal heart tracings From labor to delivery
Secondary Cord blood gases If obtained by the provider, umbilical (arterial or venous) cord pH At the time of delivery
Secondary Cases of small for gestational age undetected prenatally Neonates that were small for gestational age at time of delivery but were not detected prenatally At time of delivery
Secondary Birthweight/ birthweight percentile Neonate birth weight and percentiles according to established weight charts will be recorded At time of delivery
Secondary Incidence of category 2 or 3 tracings As defined by the National Institutes of Health-National Institute of Child Health and Human Development Fetal Heart Tracings definitions and classifications During labor
Secondary Distribution of CPR by estimated fetal weight We will assess whether there is an association between the CPR and sonographic estimation of fetal weight. Measured during ultrasound between 36 weeks gestational age and delivery of the pregnancy.
Secondary Rate of operative vaginal delivery Vaginal deliveries needing forceps or vacuum assistance At time of delivery
Secondary Neonatal Intensive Care Unit admission Percentage of neonates admitted to the neonatal intensive care unit Up to 28 days from delivery of the pregnancy
Secondary Apgar scores at 1 and 5 minute Standard assessment tool applied to all neonates in participating centers by clinical staff Scores assigned at 1 and 5 minutes of life by clinical staff.
Secondary Composite neonatal outcome The investigators will record a composite neonatal outcome including-respiratory distress, apnea, infection, hypoglycemia, hyperbilirubinemia, hypothermia, neurologic complication and neonatal death. Up to 28 days from delivery of the pregnancy.
