A quick ultrasound during labor may predict perineal tears and C-Section risk
NCT ID NCT07736183
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This study tests whether measuring the distance between the baby's head and the mother's perineum using ultrasound early in active labor can predict delivery-related injuries, such as perineal tears, and whether a C-section is needed. Researchers will compare this ultrasound measurement with standard vaginal exams in 70 first-time mothers with full-term, single-baby pregnancies. The goal is to see if this non-invasive technique offers a better way to anticipate maternal outcomes during childbirth.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If head-perineum distance proves reliable, it could give doctors a non-invasive way to predict perineal tears and the need for a C-section early in labor.
- What could go wrong
- This is a small, observational study with 70 participants. The measurement may not be accurate enough to replace standard exams, and results may not apply to all women.
