Fetal position: the longitudinal presentation of the head than characterized
Basically, all pregnant women are trying to learn more about the features of their interesting position. Therefore, quite often during the ultrasound, a lot of talk about the head presentation of the child.
What and how does the headache affect
The position of the fetus longitudinal head indicates that the head in the uterus is facing the inner throat. This arrangement is the most common and desirable for natural childbirth. Because in this case the head, which is the largest part of the body, will be the first to move along the birth canal. This contributes to the rapid and easy birth of the child.
Until 28-30 weeks the position of the child changes very often. This also applies to its presenting part. But by the end of pregnancy, the fetus is head down.In this position, most natural genera flow.
Only 3-4% are cases of pelvic presentation, which is a direct contraindication to the natural delivery.
If the position of the fetus is longitudinal - the prelying fetal head may have a different arrangement: the occipital and the insertion of the head.
The most optimal in obstetrics and gynecology is flexor occipital presentation. In this case, the leading point of movement along the channel is a small spring. With this presentation in the generic process, the child's neck is bent in such a way that it is the back of the head that appears first. This is typical for about 95% of births.
Bending insertion head
The remaining 5% in case of head presentation belong to the insertion of the head. There are 3 degrees of such placement:
Degree 1 - the position of the fetus is longitudinal, but anterior presentation, when the wire point is a large spring. With this placement, the possibility of an independent delivery is not excluded. But there is a slightly increased likelihood that this process may cause injuries to the child or mother. Deliveries are protracted, prophylaxis of hypoxia is required.
2 degree - frontal presentation, when the wire point is the forehead of the child. That he is below all other parts of the head of the fetus. In this case, natural childbirth is contraindicated. In this case, only a caesarean section can complete the pregnancy (the position of the fetus (longitudinal) is abnormal).
3 extreme - the position of the fetus is longitudinal, but there is a presentation of the face. The head in this case will go out of the birth canal back of the head. Ate the woman in labor has a sufficient size of the pelvis, and the size of the fetus is insignificant - independent delivery is not excluded. Despite this, in some cases, the facial presentation of the fetus is an indication for a cesarean section
Causes and Diagnosis
The reasons for all kinds of non-standard postures and presentations of the fetus may include the following:
- narrow pelvis;
- pathological structure of the uterus;
- placental previa;
- laxity of the abdominal wall;
- heredity and others.
The position of the fetus longitudinal head can determine the gynecologist after 28 weeks of pregnancy. This is facilitated by an external obstetric study.During one of them, the doctor places the open palm of his left hand over the symphysis and covers the part of the fetus that is presenting.
If the position of the fetus is longitudinal, the preposition is the head (the photo of which can be seen above), then during palpation a dense round part is felt. It is also very mobile and runs in the amniotic fluid. The data obtained as a result of this examination can confirm or refute vaginal gynecological examination.
When the position of the fetus is longitudinal, the presentation is the head one (an ultrasound photo confirms this), the heartbeat will be felt just below the woman's navel. Ultrasound examination will help determine the position, location of the body members, predlozhanie, the position of the fetus and its appearance.
How to adjust the previa
If your child is in the wrong position, you can try to adjust his placement. This is possible until the generic process has begun. The unstable or incomplete type of head presentation of the fetus in the uterus is subject to adjustment.
To do this, the mother must constantly change the position, often occupy the position that provokes the movement of the baby.If the baby’s head is not located directly to the exit of the uterus, but is slightly displaced, it is often necessary to lie on the side where the fetus is located.
Immediately after the position of the fetus is restored, longitudinal previa will take place - it is necessary to fix it. For this you can use a bandage. It can only be removed in extreme cases, when you need to change clothes or wash.
But the fetus can change its position at the very last moment. This occurs after the outpouring of amniotic fluid. Then the place in the uterus becomes more, and the child has where to carry out a coup.
Prevention of complications
Early hospitalization is required for those women who, after 3 weeks of pregnancy, have been diagnosed with a longitudinal position of the fetus, but an abnormal version of its presentation. This is necessary so that doctors can decide in advance on the tactics of delivery.
The best option for the wrong location of the baby - a cesarean section. In some cases, can be carried out and natural childbirth. But they are a risky option. The presence of any additional risks is fraught with not only complications, but also the death of a child.
Therefore, do not take another risk. In this case, this is unacceptable.It is better to agree to a cesarean section and be firmly convinced that the crumb after birth will be safe and sound. Do not be afraid of this operation, because it will help your child to appear on this world completely healthy and unharmed.
Be vigilant and reasonable. Successful childbirth and healthy babies!
