Pregnant mothers who choose natural delivery must first consider whether they have the conditions for natural delivery. The most important are these two conditions: 1. There are no complications between mother and child; 2. The three elements of childbirth are a normal fetus, birth canal and productivity. Regarding the three elements of childbirth, detailed explanation is needed
First of all, the fetus is normal; it cannot be too big. A fetus exceeding 4kg is considered macrosomia. The fetus cannot be deformed, and conjoined twins cannot be delivered naturally.
Secondly, the birth canal must be normal; the pregnant woman\’s pelvis must be normal, neither deformed nor narrow, and able to allow the fetus to pass; if the soft birth canal has scars or deformities, it is not suitable for natural delivery.
Again, normal labor refers to the uterine contractions of pregnant women during delivery. Normal delivery refers to normal uterine contractions, because uterine contractions are the main force that promotes the expulsion of the fetus from the mother\’s body. The uterus contracts and then forces the fetus out of the body; the labor must be neither excessive nor weak. Because too strong uterine contractions will cause the uterus to contract forcefully, it will have a series of effects on the fetus. The most obvious one is the fetus\’ lack of oxygen in the mother\’s body, which is intrauterine distress. In the absence of weakness, the mother is unable to promote cervical dilation or fetal descent.
When there are no complications for the mother and baby and the three factors of delivery are normal, pregnant women are allowed or encouraged to give birth naturally.
A cesarean section should be considered if a pregnant woman has:
1. The pelvis is obviously narrow or deformed.
2. There are special lesions or deformities in the vagina, soft birth canal, pelvis, and cervix.
3. Abnormal fetal position; such as transverse position and breech position.
4. Prepartum hemorrhage; such as placental abruption and placenta previa.
5. Scarred uterus.
6. Elderly primiparous women (over 35 years old).
7. Pregnancy complications or serious complications, such as pregnancy complicated by severe heart disease, diabetes, kidney disease, etc.
8. Those who have undergone genital tract fistula repair or old third-degree perineal tear repair, or have genital deformities.
9. Premonition of uterine rupture.
A caesarean section can be performed if the fetus has the following conditions:
1. The fetus is hypoxic in the womb.
2. Umbilical cord prolapse: The fetal heart rate is still good, and it is estimated that the fetus can survive, but normal delivery will not be possible in a short time.
3. Fetuses are precious.
