What is the reason of baby horizontal position?

summary

It's not strange for pregnant mothers that the fetal position is not correct, which is a very common phenomenon, and tongduo fetal position is not correct in the late pregnancy, so expectant mothers will be relatively worried. There are many kinds of malposition, and there are many forms of malposition, one of which is transverse position. Now let me talk to you about the reason why the baby is horizontal?.

What is the reason of baby horizontal position?

First, pelvic anomalies often occur in male pelvis or ape pelvis. The characteristics of these two types of pelvis are that the front half of pelvic plane is narrow, which is not suitable for the connection of fetal head and occipital part, and the rear half is wide, so the fetal head is easy to be connected by occipital posterior position or occipital transverse position. This kind of pelvis is often accompanied by the stenosis of the middle pelvic plane and pelvic outlet plane, which affects the fetal head to rotate forward in the middle pelvic plane. In order to adapt to the pelvic shape, it becomes persistent occipital posterior position or persistent occipital transverse position. Because the anteroposterior diameter of the flat pelvis is short and small, the diameter lines of the pelvis are small, and the transverse diameter of the pelvis is the longest, the fetal head is often in the occipital transverse position. Because the pelvis is too small, the fetal head is difficult to rotate, so the fetal head will continue in the occipital transverse position.

The second is the poor flexion of the fetal head, if it is connected by occipito posterior position. The anterior fontanel of the fetal head becomes the lowest part of the descent of the fetal head, and the lowest point often turns to the front of the pelvis. When the anterior fontanel turns to the front or side of the pelvis, it is not conducive to the flexion of the fetal head. The occipital part of the fetus turns to the rear or side to form a persistent occipital posterior position or a persistent occipital transverse position.

Third: uterine atony affects the descent, flexion and internal rotation of fetal head, which is easy to cause persistent occipital posterior position or occipital transverse position.

matters needing attention

If the fetal position is not correct, do not worry too much, emotional instability is very harmful to the health of the fetus. In addition, effective measures should be taken to correct the malposition of the fetus to minimize the impact on the fetus.
