Early Diagnosis and Intervention for Fetal Malposition in Active Labor and Its Impact on Mode of Delivery
Early Diagnosis and Intervention for Fetal Malposition in Active Labor and Its Impact on Mode of Delivery: A Randomized Controlled Trial
Women and Infants Hospital of Rhode Island
200 participants
May 1, 2024
INTERVENTIONAL
Conditions
Summary
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

Interventions
Participants will be assisted into a position lying on their side, specifically the same side as the fetal spine diagnosed by ultrasound. An inflated peanut ball will be positioned between the legs to open the pelvis. They will be asked to maintain the position for 60 minutes.
Participants will be asked to adopt any position of their choosing and to maintain it for 60 minutes. They will be asked to not use a peanut ball during the 60 minute study period.
