ARRIVE
A Randomized Trial of Induction versus Expectant Management (ARRIVE)
IRB#: 529843-2, Wake: 529843
This study compares first time moms who are induced at 39 weeks to those who are managed until 41 weeks gestation. The study looks at whether induction at 39 weeks reduces the risk of severe neonatal morbidity and perinatal mortality.
You may be qualified if the following applies to you:
- Women who have had no previous pregnancies beyond the 20 weeks,
- Pregnant with one baby or twins that were reduced to one baby before 14 weeks gestation, and are between 38 weeks and 0 days to 38 weeks and 6 days.
You may not be able to participate if:
- Gestational age greater than 20 weeks and 6 days at first ultrasound
- planned induction prior to 40 weeks and 5 days
- planned cesarean section
- signs of labor as defined as regular uterine contractions with cervical change
- fetal demise or anomalies
- heparin use during pregnancy
- Previa/accreta/vasa Previa
- active vaginal bleeding
- ruptured membranes
- cerclage
- oligo defined as a AFI less than 5
- fetal growth restriction as defined by a EFW of less than the 10th percentile
- HIV
- maternal medical illnesses
- refusal of blood products
- participation in another interventional study
- delivery planned at non-network site
