What the study is about

The goal of this randomized trial is to test if changing a person's position in labor can increase the chances of delivering their baby vaginally.

Specifically, it aims to answer the questions:

  • In fetuses who are facing upwards (occiput posterior, OP) or sideways (occiput transverse, OT) during labor, does changing the patient's position during active labor to a side-lying posture with a peanut ball increase the chances of them having a successful, spontaneous vaginal delivery?
  • Does changing the patient's position in active labor affect the position of the baby at the time of delivery?
  • Do intentional position changes in labor impact patient-perceived autonomy during their labor and delivery experience?

Participants will

  • Receive an ultrasound during labor to determine the position of their baby
  • Be asked to adopt a specific position in labor (side-lying with peanut ball) if they are randomized to the study group
  • Receive additional ultrasounds during labor to assess their baby's position
  • Fill out a questionnaire about their labor experience following the delivery of their baby

Being studied: Maternal position change to side-lying lateral with peanut ball; Free maternal position

Conditions: Cesarean Delivery Affecting Fetus; Labor Dystocia; Labor Complication
