Can a simple score or ultrasound better predict labor success?
NCT ID NCT07208552
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 88 first-time mothers to see which method—a doctor's exam (Bishop score) or an ultrasound—better predicts if labor induction will lead to a vaginal birth within 24 hours. Participants are full-term pregnant women with a single baby in head-down position. The goal is to improve how doctors decide on the best way to start labor.

Who is studied
Participants include 88 primigravida women at ≥37 weeks of gestation, each with a singleton pregnancy in cephalic presentation. All participants present with medical or obstetric indications for induction of labor, such as post-dates, oligohydramnios, mild preeclampsia, or premature rupture of membranes. Exclusion criteria include prior uterine surgery, multiple pregnancies, malpresentation, placenta previa, vasa previa, non-reassuring fetal status at admission, or maternal infections such as active genital herpes and HIV. A carefully designed sample size calculation ensures adequate power, with a final cohort of 44 women per study arm.
