Study summary

This study is a randomized, controlled, observational study. 150 nulliparous women with estimated fetal weight ≥3500g at 39-40 weeks of gestation will be enrolled as subjects in the two groups is 1:1. In the experimental group, vaginal examination will be performed at 39 to 40 weeks to assess cervical conditions. If the bishop score \<6, the balloon catheter combined with oxytocin induction will be planned at 40 weeks ±3 days. In the control group, one week to 41 weeks ±3 days will be expected. Vaginal examination will be performed again to evaluate cervical conditions. If the bishop score \<6 points, and balloon catheter combined with oxytocin induction will be performed. After 96h, their final delivery mode will be recorded. In the following 42 days postpartum, their complications and the neonatal outcome will be followed up.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 19, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
