Clinical manifestations of uterine rupture

Uterine rupture can cause very serious harm to female friends, so once the symptoms of uterine rupture appear, female friends should actively seek treatment to prevent the uterine rupture from worsening and eventually becoming untreatable. So what are the clinical manifestations of uterine rupture? We should understand some clinical manifestations of uterine rupture so that we can discover the symptoms of uterine rupture in time.

We must also know the causes of uterine rupture, because it is these factors that lead to uterine rupture in female friends. Female friends should know that the abuse of uterotonics, uterine scar rupture and obstructive dystocia are the causes of uterine rupture.

1. Bleeding Uterine rupture usually manifests as heavy bleeding, which can be divided into internal bleeding, external bleeding or mixed bleeding. Internal bleeding refers to the accumulation of blood in the broad ligament or in the abdominal cavity, resulting in broad ligament hematoma or hemoperitoneum; external bleeding refers to the discharge of blood from the vagina. The bleeding sites of uterine rupture usually include the rupture of the uterus and soft birth canal and the placental detachment surface. Bleeding from the uterus and soft birth canal usually requires damage to the large blood vessels in the area. If the soft birth canal injury does not damage the large blood vessels, it usually does not manifest as heavy bleeding or active bleeding. Bleeding on the placental detachment surface is related to the degree of placental detachment and the intensity of uterine contraction. If the placenta is not completely detached or is not discharged from the uterine cavity after detachment, it will affect uterine contraction and manifest as heavy bleeding. On the contrary, if the placenta is completely detached and has been discharged from the uterine cavity and the uterus contracts very well, there will be a small amount of active bleeding on the placental detachment surface. The above-mentioned bleeding refers to preoperative bleeding, but bleeding may also occur after surgery. The main causes are wound bleeding after removal of broad ligament hematoma or DIC bleeding, or conservative treatment of uterine bleeding. In addition to causing hemorrhagic shock, bleeding can also lead to DIC due to the maternal hypercoagulable state, excessive bleeding, and prolonged shock.

2. Infection: The most common sites of infection after uterine rupture are the pelvic cavity, abdominal cavity, pelvic retroperitoneum and soft birth canal. . The main causes of infection are: the pelvic and abdominal cavity or broad ligament are connected with the uterine cavity and vagina, through which bacteria enter; heavy bleeding after uterine rupture, severe anemia or DIC, decreased resistance and easy infection; blood accumulation in the abdominal or pelvic cavity or extraperitoneal blood, easy infection; hysterectomy or repair after uterine rupture is performed under bacterial conditions; there may be more vaginal operations during the diagnosis period after uterine rupture; long-term uterine rupture is more likely to lead to various infections in multiple parts. Another infection worth mentioning is respiratory tract infection. There are many factors that cause infection. Prolonged shock time is related to the damage of normal respiratory tract sputum discharge and defense mechanism. At the same time, factors such as aspiration cannot be ruled out.

3. Injuries that lead to damage to the birth canal and other abdominal and pelvic organ tissues and uterine rupture include injuries before and after surgical intervention. Injuries before surgical intervention include various injuries to the uterine body, lower uterine segment, cervix and vagina, and there may also be primary bladder injuries caused by fetal head compression. The injuries in the diagnostic and surgical treatment of patients with uterine rupture are many, sometimes even greater than the primary injury. Too many unnecessary vaginal operations or examinations during the diagnosis process can lead to worsening birth canal damage; improper laparotomy to clear blood or clean the fetus, placenta and fetal membranes can lead to intestinal or omentum damage; cleaning of broad ligament hematomas can cause damage to the pelvic floor blood vessels, ureters and bladder; uterine rupture lasts too long, causing more serious damage to abdominal organs.

4. Impact on the fetus The impact of uterine rupture on the fetus is mainly damage caused by bleeding at different times and to different degrees, and most fetuses die. The perinatal morbidity and mortality rates of surviving fetuses increased significantly, and long-term complications also increased significantly.

In the above article, we have introduced in detail what uterine rupture is. We know that uterine rupture is a very dangerous symptom, so uterine rupture must be treated in a timely manner. The above article introduces the causes of uterine rupture and the clinical manifestations of uterine rupture. I hope the above introduction is helpful to everyone.
