Occiput Posterior (OP)
In occiput posterior position,
your baby's head is down, but it is facing the mother's front instead of her back
. It is safe to deliver a baby facing this way. But it is harder for the baby to get through the pelvis.
What is persistent occiput posterior?
DEFINITION. Persistent OP is
when the occiput remains in the posterior quadrants of the pelvis until delivery
, whether that delivery is spontaneous or indicated for a nonreassuring fetal status or arrest of descent in the second stage.
What is persistent occiput posterior position?
Persistent occiput posterior (OP) is
associated with increased rates of maternal and newborn morbidity
. … Nonrotational operative vaginal delivery is appropriate when the maternal pelvis has a narrow anterior segment but ample room posteriorly, like with anthropoid features.
What is persistent Occipito posterior position?
There should be but one definition of persistent occipitoposterior position. It is
the condition that results in skull presentation from the rotation of the occiput backward toward the sacrum.
Why is occiput posterior position bad?
The posterior position at birth is associated with
a higher risk of short-term complications for the baby
, such as lower five-minute Apgar scores, a greater likelihood of needing to be admitted to the neonatal intensive care unit (NICU), and a longer hospital stay.
Is occiput posterior position normal?
Occiput posterior (OP) position is
the most common fetal malposition
. It is important because it is associated with labor abnormalities that may lead to adverse maternal and neonatal consequences, particularly operative vaginal delivery or cesarean delivery.
How can we stop occiput posterior?

Is posterior position bad for baby?

The primary outcome will be
operative delivery
(defined as vacuum, forceps and/or caesarean section deliveries). Secondary outcomes will be caesarean section, significant maternal mortality/morbidity and significant perinatal mortality/morbidity.
What causes Occipito posterior position?
The occipitoposterior position in the main is caused by
the adaptation of the head to a pelvis having a narrow fore pelvis and an ample anteroposterior diameter
and therefore may be considered “physiologic.”
How is Occipito posterior position diagnosed?
Fetal head position during the entire labor. Diagnosis made by transabdominal ultrasound during the first stage, by
transperineal ultrasound during the second stage
, by clinical assessment at time of delivery.
Does posterior placenta mean boy or girl?
