What does the transverse position of fetus mean?

I believe everyone knows something about the fetal transverse position, but do you know what he really means? Generally speaking, fetal transverse position rarely occurs during delivery, accounting for only 0.25% of the total number of deliveries. From a medical point of view, it is the angle at right angles between the longitudinal axis of the carcass and the longitudinal axis of the mother. In many cases, it does not represent pathological fetal position. Let's take a closer look: what does the transverse position of the fetus mean?

What does the transverse position of fetus mean? Fetal transverse position is a kind of fetal position, which refers to the posture of the fetus lying in the uterus. When the transverse fetus gives birth naturally, it is easy to give birth to the shoulder first and then the fetal head, which is easy to dystocia and even cause intrauterine asphyxia and even death. It is a dangerous fetal position. Therefore, for the safety of pregnant women and fetuses, caesarean section is generally recommended.

Reason:

Most of the findings of transverse position are related to the asymmetry between the head and pelvis, which makes it difficult for the head to enter the pelvis. Postpartum abdominal wall relaxation, polyhydramnios or twins can also occur transverse delivery. A few may be placenta previa or tumor that prevents the baby's head from entering the pelvic cavity.

symptom

(1) Fetal heart is usually heard below the navel of the mother, but it has no special diagnostic value.

(2) When doing abdominal examination, it can be found that the mother's abdomen is asymmetrical, and the fundus height is less than the estimated number of weeks of pregnancy. The fetal head can't be touched up and down the uterus, but it can be touched on the mother's side.

(3) When doing internal diagnosis, you can feel that the exposed part is relatively high, neither the fetal head nor the buttocks.

(4) Ultrasound can show that the fetal head is on the side of the mother's uterus.

(5) X-ray pelvic photography can also show that the fetus is supine.

diagnose

(1) Abdominal examination showed a transverse oval shape with a low uterine base and a cavity above the pubic symphysis. On one side of the abdomen, you can feel a big and hard fetal head, the opposite side is the buttocks, and the fetal heart on both sides of the navel is the clearest.

(2) In the early stage of labor, the exposed part is high and difficult to touch, and the cervix has expanded. Because the exposed part can't be close to the pelvic entrance, the amniotic fluid can communicate back and forth. When the uterus contracts, the fetal membrane pressure at the cervix is very high, which is easy to rupture the fetal membrane and make the umbilical cord or fetal arm prolapse.

What about the lateral position of the fetus? 1. Knee-chest position If pregnant women find that the fetus is horizontal before 37 weeks of pregnancy, they can correct the fetal position to normal through knee-chest position. Specific methods: pregnant women urinate, wear loose and elastic clothes, kneel on the bed, and keep their legs shoulder-width apart. Then put your arms on the bed, with your breasts and shoulders as close as possible to the bed surface, your knees twisted, your calves and thighs at a right angle of 90 degrees, your knees and calves attached to the bed surface, and your hips raised as much as possible. Support your whole body with the strength of your breasts and knees, and don't clamp or drag your abdomen with your thighs. Hold this position for 10 ~ 15 minutes. 2~3 times a day, 1 week.

2. Expectant mothers before moxibustion can also help correct normal fetal position through moxibustion. Specific methods: pregnant women lie flat or take a sitting position and loosen their belts. The doctor shall apply moxibustion on bilateral acupoints to the yin (outside the toes), 1-2 times a day, each time 15 minutes, 5 times as a course of treatment, and review after one week.

3. Fetal position valgus If neither of the above two methods can correct the fetal position to normal, it can be corrected by fetal position valgus at 37-39 weeks of pregnancy. Specific methods: First, pregnant women are given drugs to relax uterine muscles to prevent miscarriage. Under the monitoring of ultrasound, after the doctor touches the fetal head, he exerts force on the expectant mother's stomach with his hand, gradually turning the fetal head into the pelvic cavity and pushing the buttocks upward.

4. Cesarean section has no effect on fetal development, but it will make expectant mothers more dangerous to give birth. Therefore, in order to avoid this situation, expectant mothers can choose caesarean section, which is safer.
