Headfirst position is called the vertex position.
Feetfirst position is called a breech position.
If your baby is breech but is not too far down into your pelvis, your Health Care Professional might try to turn your baby into the proper position a few weeks before your due date.
OBJECTIVE: This study was undertaken to assess the utility of the nulliparous term singleton vertex cesarean birth (NTSV CB) measure as a quality improvement tool for use at the hospital level.
Vertex/breech. The second best-case scenario for a vaginal birth is the vertex/breech set-up. This means that if Baby A is head-down and in a good position for delivery, your practitioner may be able to manipulate Baby B from the breech position to vertex after Baby A is born.
Vertex: Head first.
Villi: Projection from a mucous membrane. Most important within the placenta in the exchange of nutrients from maternal blood to the placenta and fetus.
Vertex presentation position of the baby in the uterus, in which the baby's head enters the birth canal first. This is the most common and desirable position for birth.
~ ( vertex presentation )
The top of the head just in front of the occipital fontanel. ~ presentation describes a type of cephalic presentation where the top of the fetal head is felt through the cervix on vaginal examination.
Very low birth weight (VLBW) ...
If both babies are vertex and the labor is progressing smoothly, there would be no need for a cesarean. Most obstetricians would agree with this.
At 41 weeks, the baby setttled on a vertex presentation. According to the records (which I disagree with), my labour started around 5:30pm Nov 7th. habitually got contractions at this time of day, easing off at about 11:00pm.
Generally, in twins, if both fetuses are in the vertex (head-down) position and there are no other complications, a vaginal delivery is possible.
ECV is not attempted earlier than 37 weeks because the baby may revert back to the breech position before birth (about 4 percent of fetuses return to a breech position after a successful ECV), most babies rotate to the vertex position on their own by the 37th week, ...
The most common, and preferred, position for a baby to be in during labor is the head down, or vertex position. Babies that are lying in other positions pose challenges during delivery, including longer labor, cord prolapse and an increased need for a cesarean section.
Assess the baby's position, whether head-first (vertex) or bottom-first (breech), and determine how far the baby has moved down the birth canal (station).
Gently push on the baby's head with one finger. If the head can be pushed back, the baby is still floating (ballotable).
Somewhere between 28 and 32 weeks' gestation, a baby should turn head down in the uterus in preparation for birth, called vertex position. When a baby does not turn and has his head up and feet down, it is referred to as "breech position" and can lead to a cesarean section or difficult birth.
The safest way for a baby to be born is head first or in the vertex presentation. If the fetus is breech or transverse, the best way to avoid problems with delivery and prevent cesarean section is to try to turn (or vert) the fetus to vertex presentation (head down).
In the last weeks of pregnancy, the baby typically moves into a vertex or head-down position, where he remains until birth.
One twin is vertex (head down) and one is breech (lower part of the body comes first) about 40% of the time. One (or more) can also be transverse (baby lies across Mom's pelvis). The McCaughey septuplets were in a pyramid configuration.
This simply means that your doctor or midwife will use their hands on the outside of your abdomen to encourage your baby to get into a head down or vertex position.
Presentation refers to the position the fetus takes as your body prepares for delivery, and it could be either vertex (head down) or breech (buttocks down). In the weeks before your due date, the fetus usually drops lower in the uterus.
The majority of babies are now in the birth position, either head down (vertex) or butt down (breech), most will maintain this position until birth. Any movements that they make are more likely to be rolls from side to side.
Cephalic (Ceph) or vertex
The usual position of a baby in later pregnancy - head down.
LABOUR & BIRTH: By around week 32 of pregnancy, two-thirds of babies have adopted the normal head-down position in the uterus (womb), also known as the cephalic or vertex position. By 36 weeks of pregnancy, 95% have adopted this head-first position.
A single trial has assessed the effect of caesarean section for delivery when the second twin was in a non-vertex presentation. As would be expected, maternal febrile morbidity and need for general anaesthesia was increased with caesarean section.
* C or Ceph (cephalic) or Vx (vertex) - head down
* Br (breech) - feet or bottom first ...
If this is your first baby, he will probably settle into a head-down position in your pelvis at about 36 weeks of your pregnancy. By the time labour begins, about 96 per cent of babies are in a head-down (vertex) position (RCOG 2006a).
What if my baby is breech near the end of my pregnancy?
The babies could remain in several different positions including both being head first. However this is very rare and most often one will be in the vertex position and the other in the breach.
Mother's prenatal laboratory studies were blood type B+, VDRL-negative, Hepatitis B surface antigen-negative, rubella-immune and HIV-negative. Her pregnancy was uncomplicated. The presentation was vertex and the route of delivery was by Cesarean section with labor.
is with the baby coming (pardon the expression) butt first, with feet up by the head or folded around the abdomen. There is no increased risk of CP just because the baby is positioned this way, but any vaginal breech delivery has an increased risk of CP and damage to the baby, more so than a vertex ...
no longer automatically plan C-sections in cases of breech birth-something that's been controversial within obstetrics over the years. There's the risk that attempting a vaginal birth might result in having an emergency C-section anyway, but the C-section rate is the same for women
