Fetal malposition, either occiput posterior or transverse (OT), leads to greater risk of cesarean delivery, prolonged labor, and increased perinatal morbidity. Historically, there is a known association between epidural use and malposition that was assumed to be due to the increased discomfort of laboring with a fetus in the occiput posterior position. However, evidence now suggests that the epidural itself may contribute to fetal malposition by impacting the probability of internal rotation. Fetal malposition may be impacted by manual rotation. Manual rotation has been associated with greater rates of delivering in the occiput anterior position and lower rates of cesarean delivery.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
