Evaluation of the Impact of Rotating Posterior and Transverse Presentations At 2 Hours of Full Dilation

During labor, 20% of fetuses present in a posterior or transverse position. Among them, 90% rotate spontaneously during labor. For the remaining 10%, maintaining a posterior or transverse position leads to longer labor, increased instrumental deliveries, more cesarean sections, and more severe perineal tears. Obstetricians can intervene by manually rotating the fetus to an anterior position. Several studies have shown the benefits of this technique, but they were all conducted at full dilation or one hour after full dilation. This timing does not allow enough time for the fetus to rotate spontaneously. Additionally, manual rotation can be poorly tolerated by the patient, especially if pain management is insufficient.

Our study aims to demonstrate the benefits of manual rotation two hours after full dilation. This delay allows 90% of fetuses to rotate spontaneously, and it could help harmonize obstetrical practices.

Treatment and study plan

Mode of delivery

Device

Retrieval of delivery data, typically recorded by midwives - retrieval of data per delivery and post-delivery - Consultation of medical data on labor duration, labor onset method, estimated fetal weight, etc.

Data collected for each delivery, identical in both groups.

Primary outcomes

  1. Rate of eutocic deliveries

    Time frame: Collected at the time of delivery.

    Collection of delivery data recorded by the midwife: eutocic delivery, instrumental extraction by vacuum, instrumental extraction by forceps, instrumental extraction by spatula, emergency cesarean section (green, orange, or red code).
