The best time to correct malposition of the fetus

I believe everyone is familiar with the symptoms of malposition of the fetus. Many pregnant women may experience symptoms of malposition of the fetus. The occurrence of malposition of the fetus not only affects prevention but also affects the development of the fetus. Therefore, we recommend that pregnant women should pay attention to symptoms such as malposition of the fetus. Once the symptoms of malposition of the fetus are found during the examination, they must be dealt with in time. Below we introduce the best time to correct malposition of the fetus.

The position of the fetus in the uterus is called the fetal position. The normal fetal position should be that the longitudinal axis of the fetus is parallel to the longitudinal axis of the mother, the fetal head is at the entrance of the pelvis and is flexed, the chin is close to the chest wall, the spine is slightly bent forward, the limbs are flexed and crossed in front of the chest and abdomen, and the entire fetal body is oval, which is called occipital anterior position. Apart from this, all other fetal positions are abnormal fetal positions. In the second trimester, the fetal position may be abnormal, and will later automatically turn into an occiput anterior position. If the fetal position is still abnormal in the late pregnancy, it is called abnormal fetal position, also known as "malposition of the fetus". Common malpositions include the arm position with the fetal buttocks at the entrance of the pelvis, the horizontal position with the longitudinal axis of the fetus perpendicular to the longitudinal axis of the mother, or the oblique position. The causes of malposition of the fetus include uterine hypoplasia, uterine malformation, narrow pelvis, pelvic tumors, fetal malformation, polyhydramnios and other factors. Abnormal fetal position during delivery can cause dystocia, which often requires surgical intervention. If not handled properly, it may even endanger the lives of the mother and fetus.

1. After 28 weeks of pregnancy, abdominal, vaginal and B-ultrasound examinations confirm abnormal fetal position.

2. Breech presentation

Abdominal examination shows that the uterus is longitudinally oval, and a round, hard fetal head that feels like a floating ball when pressed can be felt at the bottom of the uterus. A soft, wide, irregular fetal buttocks can be felt above the pubic symphysis. The fetal heartbeat is most clearly heard to the left or right side above the navel. B-ultrasound examination showed that the fetal head was below the rib margin. Above the pubic symphysis is the arm or the foot.

3. Horizontal position

The uterus is transversely oval, the fetal head can be felt on one side of the mother's abdomen, and there is a relatively empty space above the pubic symphysis. The fetal heart sounds are clearest on both sides of the umbilicus. B-ultrasound examination shows that the fetal head is on one side of the mother's abdomen.

Before 28 weeks of pregnancy, because there is relatively more amniotic fluid and the fetus is relatively small, it has a larger range of movement in the uterus, so its position is not easy to fix. After 32 weeks of pregnancy, the baby grows rapidly and the amniotic fluid decreases relatively. At this time, the posture and position of the fetus are relatively fixed. Therefore, after 32 weeks of pregnancy, if the baby is still in an "abnormal fetal position", it is basically confirmed. Of course, it does not rule out the possibility that a very small number of babies will have "unexpected actions". Therefore, the most appropriate time to correct malposition of the fetus is between 30 and 32 weeks of pregnancy. Before 7 months of pregnancy, malposition of the fetus may be corrected. If the fetal position has not corrected after 8 months of pregnancy, it needs to be corrected.

In the above article, we introduced a common symptom, that is, malposition of the fetus. We know that malposition of the fetus will affect the development of the fetus, so pregnant women should pay attention to this symptom. The above article introduces in detail the best time to correct malposition of the fetus.
