NCT05175040

Brief Summary

This is a randomized controlled trial to determine whether prophylactic manual rotation for fetuses identified to have persistent occiput posterior or occiput transverse presentation (POP/OTP) at the initiation of the second stage of labor in nulliparous individuals reduces rates of operative delivery, second stage of labor duration, and resultant adverse clinical outcomes compared to standard management of the second stage of labor.

Outcome Measures

Primary Outcomes (1)

  • Number of participants in each group who undergo operative delivery

    Number of participants in each group who undergo a cesarean section or an instrumental delivery (vacuum or forceps) as a composite outcome

    From randomization until delivery, up to 5 hours

Secondary Outcomes (18)

  • Number of participants in each group who undergo operative vaginal delivery

    From randomization until delivery, up to 5 hours

  • Number of participants in each group who undergo cesarean delivery

    From randomization until delivery, up to 5 hours

  • Number of minutes in the second stage of labor in each group

    From randomization until delivery, up to 300 minutes

  • Number of participants in each group with composite maternal morbidity

    From randomization until hospital discharge, an expected average of 3 days

    From randomization until delivery, up to 5 hours

  • +13 more secondary outcomes

Study Arms (2)

Prophylactic manual rotation

EXPERIMENTAL

Prophylactic manual rotation involves a vaginal examination performed with an obstetric provider's hands to turn the baby from a position in which the baby's face is looking up in the direction of the ceiling (occiput posterior) or to the side (occiput transverse) to a position in which the baby's face is looking down in the direction of the mother's spine (occiput anterior). Prophylactic manual rotation will occur at the initiation of pushing once the individual achieves complete cervical dilation.

Procedure: Prophylactic manual rotation

Sham rotation

SHAM COMPARATOR

Sham rotation involves a vaginal exam that obstetric providers commonly do with their hands to assess cervical dilation and fetal position during routine labor, and will occur at the initiation of pushing once the individual achieves complete cervical dilation.

Procedure: Sham rotation

Interventions

Prophylactic manual rotation, performed in the experimental arm, involves a vaginal examination performed with an obstetric provider's hands to turn the baby from a position in which the baby's face is looking up in the direction of the ceiling (occiput posterior) or to the side (occiput transverse) to a position in which the baby's face is looking down in the direction of the mother's spine (occiput anterior). Prophylactic manual rotation will occur at the initiation of pushing once the individual achieves complete cervical dilation, performed by a trained study investigator (M.D. or midwife) to maintain blinding of the patient's primary obstetrician.

Prophylactic manual rotation
Sham rotationPROCEDURE

Sham rotation, performed in the comparator arm, involves a vaginal exam that obstetric providers commonly do with their hands to assess cervical dilation and fetal position during routine labor, and will occur at the initiation of pushing once the individual achieves complete cervical dilation. Duration of the vaginal exam for sham rotation will be consistent with that used for prophylactic manual rotation and will be performed by a trained study investigator (M.D. or midwife) to maintain blinding of the patient's primary obstetrician.

Masking Details
Both the study participant and her primary obstetrician will be blinded to the assigned randomization arm prior to delivery, as involvement in this research study should not change their care. Clinical management will be left to the discretion of each participant's primary obstetrician managing her labor, according to standard obstetrical care, who again will not be involved in the research-related study procedures.
