4P Trial Summary

This trial will compare the effects of two different techniques for delivering the baby's head during vaginal birth.

Who is the study for?
This trial is for first-time mothers with a single, non-anomalous baby in the correct head-down position at full term who are planning to give birth vaginally. Women who've given birth before, have had genital surgeries or malformations, multiple babies at once, or any fetal conditions that make labor risky can't join.Check my eligibility
What is being tested?
The study is looking into whether hip extension during childbirth (as opposed to the common practice of hip flexion) reduces severe perineal tears when the baby's head appears. It compares this new method against the standard care given during delivery.See study design
What are the potential side effects?
Since this trial involves birthing positions rather than medications, side effects may include discomfort from positioning and potential differences in perineal trauma outcomes compared to usual birthing practices.
