What is the mechanism of 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.”
What is the meaning of Occipito posterior position?
[ ŏk-sĭp′ĭ-tō-pŏ-stîr′ē-ər, -pō- ] n. A cephalic presentation of the fetus with the occiput turned toward either the right or left rear quarter of the mother’s pelvis.
What is the outcome of Occipito posterior position?
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 does op mean in labor?
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.
Which type of pelvis causes Occipito posterior position?
The shape of the pelvis: anthropoid and android pelvises are the most common cause of occipito-posterior due to narrow fore-pelvis.
What is the mechanism of labor?
Mechanism of labor The mechanisms of labor, also known as the cardinal movements, involve changes in the position of the fetus’s head during its passage in labor. These are described in relation to a vertex presentation.
What is the mechanism of labour?
What is ROP position in pregnancy?
In the right occiput posterior position (ROP), the baby is facing forward and slightly to the right (looking toward the mother’s left thigh). This presentation may slow labor and cause more pain.
What is Occipito anterior position?
Some babies are in the direct occiput anterior position, which means their nose is facing your tailbone. However, many babies are rotated slightly to one side. In the left occiput anterior position, your baby’s head is slightly rotated toward the left.
What is Loveset maneuver?
Løvset’s manoeuvre (luv-setz) n. rotation of the trunk of the fetus during a breech birth to facilitate delivery of the arms and the shoulders. [ J. Løvset (20th century), Norwegian obstetrician] A Dictionary of Nursing.
What is cephalic ROP?
In Right Occiput Posterior (ROP), baby is head down and the back is to the side- the right side. ROP is the most common of the four posterior positions. Attention: The ROP baby may need a longer time for fetal rotation in labor.

What is posterior position of baby?
A baby that is head-down but facing your abdomen is said to be in the posterior position. A small percentage of babies end up in this position at birth. If your baby is in the posterior position, you may be in for a more complicated delivery. The technical term is occiput posterior (OP) position.
What is occipito posterior postion?
OCCIPITO POSTERIOR POSITION “In a vertex presentation where the occiput is placed posteriorly over the sacroiliac joint, sacrum called occipito-posterior postion.” 2.
What is the difference between malposition and occipito posterior?
MALPOSITION “ Malposition refers to any position of the vertex other than the flexed occipito-anterior one.” OCCIPITO POSTERIOR POSITION “In a vertex presentation where the occiput is placed posteriorly over the sacroiliac joint, sacrum called occipito-posterior postion.”
What is the meaning of occipitoposterior?
oc·cip·i·to·pos·te·ri·or po·si·tion. A cephalic presentation of the fetus with its occiput turned toward the right (right occipitoposterior, ROP) or to the left (left occipitoposterior, LOP) sacroiliac joint of the mother.
What is the difference between anterior and posterior rotation of occipital region?
• In majority of cases (90 %), ANTERIOR ROTATION of occiput occurs and follows the course like that of an occipito anterior position and it is favorable position • But as the posterior position occasionaly gives rise to dytocia, it is described along with malpositions 5.
