Some women in the second trimester of pregnancy, that is, the fifth to seventh month of pregnancy, for some reason, the cervix slowly opens, and the pregnant woman herself has no pain or bleeding except a slight feeling of lower abdominal pressure, until one day, on a sunny day, the amniotic membrane suddenly breaks, and amniotic fluid (the liquid that protects the fetus in the uterus around the fetus) flows out of the body in large quantities, leading to the onset of labor pains, and then the pain begins after several powerful uterine contractions.

As mentioned above, most premature births caused by cervical weakness occur before 7 months of pregnancy. Therefore, children born in a hurry are too immature to adapt to the survival of the uterus and often die young. Moreover, cervical weakness will not heal automatically. If it is not treated, it will continue to exist, so rapid early water breakthrough, premature delivery and premature death will happen again and again, which will make pregnant women consume their physical strength and damage their physical and mental health, but they still get nothing.

Another rare cervical weakness can even cause a series of abortions, that is, the fetus repeatedly miscarried four months ago, leading to habitual abortion.

There are many reasons for cervical weakness, most of which seem to have a causal relationship with the injury during childbirth, the laceration of the cervix and the mechanical injury of the cervix during induced abortion (curettage and abortion), but they are rarely born for the first time by pregnant women unless they are congenital cervical weakness. The reason is congenital cervical muscular dysplasia, or more endocrine and collagen problems.

Second, treatment.

The treatment of cervical weakness is usually to suture the cervix with various surgical methods after 16 weeks of pregnancy (that is, after the fourth month of pregnancy), and then pull out the suture when the fetus reaches the 38th week, so that the fetus can give birth naturally and smoothly. During the operation, you need general anesthesia or hemianesthesia, and stay in hospital for several days to avoid abortion or premature delivery due to surgical stimulation. The commonly used surgical methods are McDonald's operation and Shirodker operation. The former used thick silk thread, while the latter used thick flat thread to suture the internal uterine neck moderately. In addition, there are cases where the cervical epithelium is removed and sutured, or the maternal skin is cut and sutured with dermal strips. The latter operation is complicated and time consuming, but it can be done once and for all. As long as you do it once, you can repeat it after natural pregnancy and natural delivery. However, sometimes due to dystocia, the uterus is almost completely damaged, so it is impossible to suture the cervix with the above method. Therefore, we have to perform laparotomy after 4 months of pregnancy, suture the cervix in the abdominal organs, and then perform laparotomy after the fetus matures.

If it is habitual heavy labor caused by cervical insufficiency, Lacey operation can be done before pregnancy. (Eyelash surgery), through plastic surgery to make the loose cervix become normal caliber, so as to achieve normal pregnancy. But caesarean section is the best way to give birth. The fetus may puncture the surgical site during delivery. In addition, you can also press the internal uterine neck from the vagina with a pessary at the beginning of pregnancy until 16 weeks of pregnancy, then suture the cervix and take out the pessary, which can protect the fetus. When the fetus grows up and the stitches are removed, the fetus can be born naturally. However, its disadvantage is: the pessary must be replaced once a week, otherwise the vaginal part is prone to uterine pressure ulcers, and it is easy to stimulate the uterus and cause abortion when replacing the pessary.

Cervical weakness is a very common obstetric disease, but it is a treatable disease with good therapeutic effect. If you have the above symptoms, you might as well see an obstetrician. Maybe it will solve your long-term troubles!
