Variations in fetal presentations include face, brow, breech, and shoulder. Occiput posterior position (facing forward, toward the mother's pubic bone) is less common than occiput anterior position (facing backward, toward the mother's spine).
If a fetus is in the occiput posterior position, operative vaginal delivery or cesarean delivery is often required. In breech presentation, the presenting part is a poor dilating wedge, which can cause the head to be trapped during delivery, often compressing the umbilical cord.
15 Αυγ 2023 · Head down, face up. When a baby is head down, face up, the medical term for it is the cephalic occiput posterior position. In this position, it might be harder for a baby's head to go under the pubic bone during delivery. That can make labor take longer.
Occiput posterior positions, including direct OP, LOP (Left Occiput Posterior) and ROP (Right Occiput Posterior) are positions favored by certain internal pelvic shapes. This position has some obstetrical significance.
Right Occiput Transverse (ROT) is a common starting position in which the baby has a bit more likelihood of rotating to the posterior during labor than to the anterior. Right Occiput Posterior usually involves a straight back with a lifted chin (in the first-time mother).
26 Ιουν 2024 · 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 forceps- or vacuum-assisted vaginal birth or cesarean birth.
24 Φεβ 2010 · The purpose of this paper is to describe nine prevailing concepts that guide labor and birth management with an occiput posterior fetus, and summarize evidence to clarify the state of the science. Methods: A search was conducted of the databases of PubMed and the Cochrane Library.
