LSCA fetal position

The first part of the fetus to be exposed is the fetal part: during pregnancy or delivery, the part of the fetal body in the mother's abdomen is closest to the mother's uterine entrance (cervix), which is called the first exposed part of the fetus. It is called fetal position. So, what does fetal position LSCA mean? What should be done if fetal position LSCA occurs? Let’s have a simple understanding and knowledge of this issue. I hope the following points will be of some help to everyone!

Normally, the fetus continues to grow until 28 weeks and floats freely in the amniotic fluid of the pregnant woman; but after 8 months, the body becomes larger, the fetal head position gradually becomes heavier and faces down, and most of them are fixed in the head-down position when the pregnant woman is about to give birth. .

Therefore, during childbirth, about 96% of fetuses come from the head, so it is called the normal fetal position-the head position. The head is the largest part of the fetus' body. As the saying goes: "The head has been through", so the head is smooth and natural for delivery.

The normal fetal position, "front occipital position" is the most effective position. In order to complete a smooth and natural delivery on the mother's pelvic center line, the head should be kept away from the chest as much as possible, which can open up the occipital bone of the fetus and enable it to pass through the birth canal quickly. It is called "occipital anterior position". The occipital bone of the fetal head is close to the upper part of the mother's pelvis. It is the normal position of the head and can be transferred smoothly.

Abnormal fetal position is one of the common causes of dystocia in pregnant women. During childbirth, the occipital position (normal fetal position) accounts for about 90%, while the abnormal fetal position accounts for about 10%. Among them, the abnormal position of the fetal head is mostly, and due to the rotation of the fetal head in the pelvis, there are persistent occipital transverse position and long occipital position. The later part. And because the fetus's head is not flexed and extended well, the first contact, the first contact, etc., the face is exposed, accumulating about 6% to 7%. Fetal abnormalities occur in about 3% to 4%, and shoulder abnormalities are very rare. In addition, a type of polymer was exposed for the first time.
