Definition: Relationship between the longitudinal axis of fetus and mother: longitudinal (resulting in either cephalic or breech presentation) oblique (unstable, will eventually become either transverse or longitudinal) transverse (resulting in shoulder presentation) back up; back down (indication for vertical uterine incision during cesarean ...
In obstetrics, position is the orientation of the fetus in the womb, identified by the location of the presenting part of the fetus relative to the pelvis of the mother. . Conventionally, it is the position assumed by the fetus before the process of birth, as the fetus assumes various positions and postures during the course of chil
The increase of this probability is gradual and identical for breech and cephalic presentations during this period. In the third period, from the 36th gestational week onward, the incidence of cephalic and breech presentations remain stable, i.e. breech presentation around 3–4% and cephalic presentation approximately 95%.
External cephalic version (ECV) is a process by which a breech baby can sometimes be turned from buttocks or foot first to head first. It is a manual procedure that is recommended by national guidelines for breech presentation of a pregnancy with a single baby, in order to enable vaginal delivery.
A breech birth is the birth of a baby from a breech presentation, in which the baby exits the pelvis with the buttocks or feet first as opposed to the normal head-first presentation. In breech presentation, fetal heart sounds are heard just above the umbilicus. Babies are usually born head first. If the baby is in another position the birth may ...
There are two types of locked twins: breech/vertex and vertex/vertex. In breech/vertex presentations, which are much more common, the first twin is in the breech position, presenting feet-first, and the second is in the cephalic (vertex) position, presenting in the normal head-first manner. [2]
In the brow presentation, the head is slightly extended, but less than in the face presentation. The chin presentation is a variant of the face presentation with maximum extension of the head. Non-cephalic presentations are the breech presentation (3.5%) and the shoulder presentation (0.5%). [1]
A spontaneous rupture that occurs early in labor may actually be related to other complications resulting in delayed labor. These complications may include a contracted pelvis, breech presentation, or occipito-posterior position. PROM: premature rupture of membranes. This term describes a rupture of the membranes that occurs before the onset of ...
