alert! 5 major reasons for female uterine rupture

Uterine rupture in women refers to a laceration of the uterine body or lower segment during delivery or pregnancy. It is a serious obstetric complication that threatens the lives of mother and child. The main causes of death were hemorrhage and infectious shock. Uterine rupture mostly occurs after 28 weeks of pregnancy, and is most common during delivery. So, what are the causes of uterine rupture? What are the early warning signs so that it can be prevented in time?

1. Too many abortions

She did not take effective contraceptive measures, and often had unexpected pregnancies, and had to have multiple abortions, which caused the endometrium to become very thin and undergo pathological changes. Especially for those who have experienced uterine perforation, the uterine wall muscles will find it difficult to resist the strong uterine contractions during delivery, resulting in threatened uterine rupture or even uterine rupture.

2. The fetal presenting part is blocked during delivery

If the fetus is too large, the fetal head and pelvis are not proportional, the fetus is in an abnormal position, or the fetus has hydrocephalus, the fetal presenting part may be blocked during delivery, causing strong contraction of the uterine muscles, resulting in pulling, stretching, and thinning of the muscles in the lower uterus, and causing threatened uterine rupture or uterine rupture.

3. Scars or lesions on the uterus

If the time after the cesarean section is too short or the incision heals poorly, or the uterus has undergone a myomectomy, the scar may easily crack during the next pregnancy and delivery, leading to uterine perforation or rupture.

4. Improper use of oxytocin during childbirth

Reasonable use of oxytocin can cause the uterine muscles to contract, the cervix to dilate, and promote delivery. However, the indications must be strictly followed when using it, and abuse must be avoided. For example, it cannot be used when the fetal presenting part has not entered the pelvis, otherwise it may easily lead to threatened uterine rupture or even uterine rupture.

5. Pregnancy with placenta previa

Placenta previa is implanted in the lower part of the uterus, where the muscle tissue is weak. When the cervix is ​​torn and stretched upward, the lower part of the uterus will rupture.

Discomfort and critical symptoms of uterine rupture

Generally speaking, threatened uterine rupture occurs first, which is more common when the labor lasts for a long time and the fetal head has not yet descended. The uterus contracts frequently and very strongly, even showing tonic contractions, causing the mother to feel irritable, severe lower abdominal pain, rapid breathing, increased pulse, and excessive pressure on the bladder, resulting in hematuria. During contractions, the muscles in the lower part of the uterus are stretched very long, thin and bulge, and a ring-shaped depression can be seen at the navel, making the uterus appear gourd-shaped.

When the uterus ruptures, the mother will suddenly feel severe tearing abdominal pain at first. The pain will be temporarily relieved as the uterine contraction stops, but she will soon turn pale, break out in cold sweats, and go into a state of shock. At this time, fetal movement stops, fetal sounds disappear, and the uterus shrinks and shifts to one side of the abdomen. When there is a lot of bleeding in the abdominal cavity, the abdominal wall will become like a board and the entire abdomen will be tender. If the uterus has not completely ruptured and has not shrunk, there will only be obvious tenderness in the lower abdomen.
