Causes of stillbirth at eight months of pregnancy

A woman who is eight months pregnant is considered to be in the late stage of pregnancy. She should pay more attention at this time because the fetus is particularly fragile at this time. Various situations may occur if one is not careful. The mother can feel it when something happens. Therefore, if the expectant mother feels abnormal, she should go to the hospital for a check-up. Stillbirth is particularly easy to occur. So what is the cause of stillbirth in eight months of pregnancy?

When a fetus dies in the womb after 20 weeks of pregnancy, it is called stillbirth. If the fetus dies during delivery, it is called stillbirth, which is also a type of stillbirth.

In about half of stillbirth cases, there are no signs during pregnancy that there is a problem with the fetus, so most parents lose their fetus without realizing it. Fetal death can usually be delivered naturally within two weeks, and choosing to wait for natural delivery does not pose much risk to the health of the expectant mother. like

  Symptoms : 1. Fetal movement stops, fetal heart rate disappears, and the uterus stops expanding.

2. The fundus of the uterus and abdominal circumference shrink, and the feeling of breast distension disappears and shrinks.

3. If the fetus remains still for too long, it may cause the expectant mother to feel general fatigue, loss of appetite, abdominal distension, postpartum hemorrhage or disseminated intravascular coagulation. About 80% of fetal death are delivered naturally within 2-3 weeks. If the fetus is still not expelled 3 weeks after death, the degenerative placental tissue releases thromboplastin into the maternal blood circulation, activating coagulation factors in the blood vessels and easily causing disseminated intravascular coagulation (DIC). If the fetus dies in utero for more than 4 weeks, the chance of DIC increases, which can cause severe bleeding during delivery.

  Causes : 1. Placental and umbilical cord factors: such as placenta previa, placental abruption, vasa previa, acute chorioamnionitis, velamentous adhesion of the umbilical cord, umbilical cord knotting, umbilical cord prolapse, umbilical cord around the neck, etc., massive placental bleeding or umbilical cord abnormalities, leading to fetal hypoxia.

  2. Fetal factors: such as severe fetal malformation, fetal growth restriction, twin-twin transfusion syndrome, fetal infection, serious genetic diseases, maternal-fetal blood type incompatibility, etc.

  3. Factors related to pregnant women: severe pregnancy complications, such as gestational hypertension, antiphospholipid antibody syndrome, diabetes, cardiovascular disease, shock caused by various reasons, etc. Local factors in the uterus, such as excessive uterine tension or strong contraction, uterine malformation, uterine rupture, etc., can cause local ischemia and affect the placenta and fetus.
