The position of the fetus is the stable arrangement of the baby in the uterus, in which he will be born to the light. It is characterized by the ratio of the axis of the fetus to the axis of the uterus. In this case, the axis of the fetus is an imaginary line that runs from the back of the neck to the tailbone on the back of the child.
What does it mean - the position of the fetus is unstable?
The unstable position of the fetus can be said if, after 30 to 32 weeks of gestation, the baby is placed head towards the cervix , and its back lies not clearly longitudinally, but is somewhat inclined.
Talking about the unstable position of the fetus, for example, at 20 weeks, does not make sense. After all, at this time of pregnancy the child is surrounded by enough free space so that he can constantly change the position of his body. Special mobility is different for children whose mothers have polyhydramnios and, as a consequence, overgrowth of the uterus.
The unstable position of the fetus, as a rule, is determined during the ultrasound. Often, at the conclusion of an ultrasound scan conducted in the 2nd trimester of pregnancy, the doctor indicates the unstable position of the fetus, which causes concern for future mothers about what this means. Such a phenomenon is not a pathology on the given dates and it is not necessary to indicate it in the conclusion.
Unstable position of the fetus - what to do?
If this position of the fetus is observed at week 32, then it can be dangerous that the baby will remain in the "oblique" position, or settle across the uterus, which will lead to the need for a cesarean section. In such situations, gynecologists advise women to perform special exercises, so that the unstable position of the baby has changed to the right one.
It is best to do exercises in prone position. First you need to lie for 10 minutes on one side, and then gently turn over on the other side. Exercise should be repeated 2-3 times. It is not necessary to perform exercises in the presence of detachment of the placenta , scar on the uterus, decompensated heart defects in the fetus. When the child takes the right position, to secure from changing his posture, a woman is recommended to wear a bandage.
The reasons for taking a transverse pelvic or oblique position by the baby are very diverse. Usually, it is impossible to establish precisely the factor that influenced the occupation of the wrong position. Similar obstetric pathology is more common in women:
- having anatomical pathologies of the uterus;
- with excess amount of amniotic fluid;
- clinically narrow pelvis;
- the pelvis, narrow in comparison with the size of the fetus;
- low placenta previa;
- at women who give birth not for the first time.
If the baby does not occupy the "classical" position in the uterus during childbirth, then the oblique or transverse presentation of the fetus is spoken, and the woman undergoes a caesarean section before the fights, because at birth, in this presentation, the risk of the fetal and umbilical cord from the uterus falling, water, other severe cases, which may lead to the death of the child and mother and child.
