What is op in obstetrics?

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. (See “Occiput transverse position”.)

What does op mean during labor?

Occiput Posterior (OP) It is safe to deliver a baby facing this way. But it is harder for the baby to get through the pelvis. If a baby is in this position, sometimes it will rotate around during labor so that the head stays down and the body faces the mother’s back (OA position).

What is pregnancy malpresentation?

Fetal malpresentation and fetal malposition are frequently interchanged; however, fetal malpresentation refers to a fetus with a fetal part other than the head engaging the maternal pelvis. Fetal malposition in labor includes occiput posterior and occiput transverse positions.

What is an op baby position?

The technical term is occiput posterior (OP) position. This term refers to the fact that the back of your baby’s skull (the occipital bone) is in the back (or posterior) of your pelvis. You may also hear this position referred to as “face-up” or “sunny-side up.”

What is persistent op position?

Persistent occiput posterior (OP) is associated with increased rates of maternal and newborn morbidity. Its diagnosis by physical examination is challenging but is improved with bedside ultrasonography. Occiput posterior discovered in the active phase or early second stage of labor usually resolves spontaneously.

How common is op birth?

The prevalence of the OP position is 15 to 32% at the onset of labour [15-18], 10 to 20% early in the second stage of labour and 5 to 8% at delivery [2,17,19,20].

What is the difference between Malpresentation and malposition?

Malpositions are abnormal positions of the vertex of the fetal head (with the occiput as the reference point) relative to the maternal pelvis. Malpresentations are all presentations of the fetus other than vertex. The fetus is in an abnormal position or presentation that may result in prolonged or obstructed labour.

What is the most common Malpresentation?

Breech presentation is the most common malpresentation, with the majority discovered before labour. Breech presentation is much more common in premature labour. Approximately one third are diagnosed during labour when the fetus can be directly palpated through the cervix.

Is Sunny Side Up delivery more painful?

The sunny side up, or posterior position, puts baby’s head where it is more likely to get wedged against the pubic bone. When this happens, pressure is placed on your spine and sacrum and can cause a longer and more painful delivery.

What are the causes of malpresentations and malpositions?

Malposition: occipito-posterior. Malpresentations: anything except vertex as face, brow, breech, shoulder, cord and complex presentations. Causes of Malpresentations and Malpositions Defects in the powers: Pendulous abdomen: laxity of the abdominal muscles.

What is the difference between fetal malpresentation and malposition?

fetal malpresentation occurs when the part of the fetus which is closest to the pelvic inlet is not the vertex of the fetal head, whereas fetal malposition occurs when the occiput of fetuses who are in vertex presentation is rotated so that it is not oriented anteriorly in the maternal pelvis

Is it possible to have a normal labour with malpresentation?

The management of malpresentation is dependent on the presentation. If the chin is anterior (mento-anterior) a normal labour is possible; however, it is likely to be prolonged and there is an increased risk of a C-section being required 90% of malpositions spontaneously rotate to occipito-anterior as labour progresses.

When is breech presentation the most common malpresentation?

Breech presentation is the most common malpresentation, with the majority discovered before labour. Breech presentation is much more common in premature labour. Approximately one third are diagnosed during labour when the fetus can be directly palpated through the cervix.
