What are the positions of the fetus?

The location of the baby in the mother's tummy is an important factor in pregnancy. After all, it depends on the position of the fetus that the degree of severity of the births, their course and the end result depends. If the crumb is normal, then problems should not arise. In this case the delivery is natural. If the position of the child is not the same as what nature intended it, then a cesarean section can not be avoided. Most likely, this option will be offered to a woman after ultrasound, conducted in the last weeks of pregnancy. On the screen of the apparatus of ultrasound diagnostics, the small body of the baby, its position, position is well seen. The kind of fruit will tell both the doctors and the woman the right decision.

Position and presentation: what is the difference?

Many future mothers often confuse the terms. Therefore, before talking about the specific positions of the fetus in the womb, it is necessary to explain the meaning of these words. So, about everything in order. The position of the fetus is the ratio of the axes of the uterus itself and the position of the crumbs. At its definition physicians are guided on a conditional line that passes from a head to a basin of the kid. If the axes coincide, then we can talk about the longitudinal position. When they are perpendicular to each other, the carapace lies in the transverse position. The middle variant between the two above described points to a slanting position.

Preposition is determined by the part of the body that is in the immediate vicinity of the cervix. Accordingly, it is the head or pelvic. In the oblique or transverse arrangement of crumbs, the presentation can not be fixed. In addition, the position of the baby is determined based on the reversal of the child's back against the sides of the uterus. If it is facing the left wall, talk about the first of its variety. The second position is called the pose on the contrary. Sometimes the back is facing the front or back of the uterus. In this case, we are talking about the form of the fetus. The species of the fetus are named respectively: front and back. By the way, up to the 34th week of pregnancy the baby can change his position in the womb. After this period, the situation remains stable, since in a tight space the crumb can no longer "roam".

Head presentation

It dominates in general statistics, since it is characteristic for approximately 95% of cases. Ideally, if the baby is nape to the cervix. In this case, his chin is pressed to his chest, and the head is tilted. The first point that goes through the birth canal is a small fontanel located at the junction of the parietal and posterior bones of the skull. In this case, two types of crumb position are distinguished. So, 1 position of the fetus is called anterior occipital presentation. It is characterized by the fact that the baby's face is turned back (in relation to the mother's body). The posture is observed in 90% of cases of pregnancy. It is the most optimal for successful delivery.

There is also a 2 position of the fetus, called the posterior occipital presentation. In this case, with respect to the body of the parent, the person is turned forward. This greatly complicates the process. During childbirth the baby can take the right position, but this often takes a long time. The process can be delayed.

Varieties of head presentation

This is not all forms of head presentation. Among other things, it is divided into so-called extensor species, when the head of the carapace is elevated to a certain degree:

• Anterior preposition. He has a small degree of extension. The leading point is a large fontanel, which is located at the junction of the frontal and parietal bones. To give birth naturally in this case is possible, but the process is much more difficult and longer. The thing is that the head of the fetus enters the mother's pelvis the largest part of it. In fact, such a pose of crumbs is an indication for cesarean section.
• The frontal position. It occurs in 0.5% of cases. If the child's size is normal or large, passing through the birth canal is impossible. An operative intervention is prescribed.
• Face preface - the maximum degree of extension of the fetal head. This situation is fixed only in 0.05% of births. A natural appearance of a baby is possible, but it can become traumatic for both the mother and the child.

The extensor presentation of crumbs is diagnosed by the obstetrician directly during labor with the help of vaginal examination.

Head presentation and fetal position

The front view of the occipital presentation at the first position of the baby is the most convenient option for normal delivery. And fortunately, the most common. As already mentioned, at the first position the kid is turned with the back to the left side of the uterus. In this situation, he moves "to the exit" with the smallest diameter of the head. That is, it can easily transform, stretch and narrow to make it easier and faster to pass through the birth canal.

If the back of the crumb is turned to the right side of the uterus, this is already the occipital presentation in the second position. The situation is not so exemplary. In this case, the chances of a so-called syndrome of a clinically narrow pelvis increase. The woman has strong, but unproductive labor, which slows down or stops altogether. To the baby took a comfortable position - the first position, a woman needs to relax. So the crumb will be easier to sink down without facing the placenta, if it is on the left or on the top wall. The doctor will prompt correct postures that will help the baby to rise in the womb, turning the head and face to the right, and the backrest to the left.

Pelvic presentation

It occurs in 5% of cases. The position of the fetus in this case does not affect the process of birth. Pelvic presentation is different:

• The first position of the fetus is the legs forward. In this case, the first are born limbs. To avoid this, the obstetrician detains the appearance of crumbs in light: he prevents his hand from moving freely. The extremities do not drop out. The karapuz has the opportunity to turn the buttocks forward. If this happens, the birth will be less dangerous.
• The second position of the fetus with pelvic presentation is gluteal. It is more favorable for the baby, and for his mother. Despite this, the pelvic presentation alone is unnatural. In this case, many future mothers doctor recommends cesarean section in order to protect the mother and her baby from unnecessary injuries and painful sensations.

Is it necessary to have a cesarean?

Pelvic presentation is not a direct indication for an operative intervention. Fetal positions in this case are an additional, not the main factor, influencing the decision of medical personnel. Doctors consider the situation in the complex, taking into account other points:

1. The age of the future mother, the size of her pelvis.
2. The course of previous pregnancies of a woman, the features of childbirth.
3. The size of the crumbs. With pelvic presentation, a fruit weighing more than 3.5 kilograms is already large. With conventional, this figure is 4 000 kg.
4. The sex of the baby. Strangely enough, but it is very important. It turns out that for girls the pelvic presentation is not dangerous. But the boys at birth can be injured genitals.

What to do in this situation?

If the ultrasound showed a pelvic presentation, before the 34th week the woman is able to change the situation. Learning about the wrong position of the fetus, she must perform some exercises:

• It is necessary to lie on the right side and hold in this position for about 10 minutes, then quickly turn to the left side. Exercise should be repeated 4 times in a row. Do it several times a day before eating.
• It is recommended to stand in the knee-elbow position once a day for 15 minutes.

Coupling in the womb is facilitated by swimming in the pool. Therefore, if you can buy a subscription, you need to use it. When the crumb will turn over on the head, be sure to wear a bandage for several weeks to fix its position. If this did not happen, two weeks before the birth the future mother is sent to a hospital. There, doctors decide how the process will go. By the way, before physicians were tortured manually turn the baby, massaging the pregnant abdomen. But then this method was abandoned because of the high risk of complications: premature birth, placental abruption, impaired cranial condition.

Slanting or transverse location

In this situation, it is impossible to determine the presentation of the fetus. The position is a direct indication of caesarean section. The oblique or transverse position of the baby in the womb occurs in 0.4% of cases. And if earlier during the birth the doctors tried to grab the crumb by the foot and flip it, today this method is not applied. The technique was quite traumatic for the baby, and for his mother. Sometimes a coup is performed with a twins giving birth. But only in the case when the first child was born, and the second one suddenly took a transverse position.

The reasons for the oblique or transverse position of the fetus may be different. Among the main factors - tumors in the uterus, fibroids. Education prevents the baby from lying in a natural posture. Sometimes this happens when the child is very large or his neck is encircled by a short umbilical cord: it restricts its movement. Another reason is the numerous births in a woman, when her uterus has suffered from numerous sprains. At an oblique or transverse position the woman needs to perform all those exercises, as with pelvic presentation. In this case, it is also recommended to lie more time on the side, towards which the back of the crumb is turned. A woman is hospitalized 3 weeks before the expected delivery. And if the situation has not changed, it is being prepared for prompt intervention.

Fruit position in double

The position and type of the fetus are established during routine ultrasound diagnosis. Sometimes during this research, future parents will learn about the surprise that nature has prepared for them: they will have twins! After euphoria, they begin to wonder whether natural delivery is possible in this situation. Of course, this is quite realistic, but only in two cases: if both babies occupy the head previa, or the baby that is closer to the cervix, has this position, and the other is located with the buttocks forward. When the leading baby has a "pelvic pose," cesarean is recommended. The thing is that at the time of the birth of the buttocks of the first-born, children in the womb can catch heads, which is fraught with trauma. It is clear that in the oblique or transverse position of the surgical intervention can not be avoided. And even if the twins in the womb are in the right position, the decision on the method of delivery is made by the medical staff, taking into account many factors.
