stillbirth

After 20 weeks of pregnancy, a pregnant woman is called a stillbirth in the fetal death palace, about one out of every two hundred pregnancy cases. (The fetus who died during childbirth is called stillbirth, which is also a type of stillbirth.) Since about half of stillbirth cases have no signs at all during pregnancy that indicate a problem, most parents lose without realizing it. fetus. Pregnant women may suspect something when the fetal movement stops suddenly. More than half of stillbirths are caused by fetal hypoxia. The reasons for hypoxia are placental factors such as placenta previa, early placental dissection, umbilical cord prolapse, umbilical cord knots, and umbilical cord around the neck to affect blood supply; fetal factors such as multiple births, intrauterine growth retardation, Teratosis; maternal factors such as pregnancy-induced hypertension syndrome, diabetes, expired pregnancy; uterine local factors such as excessive uterine tension or contractility, uterine rupture, etc. After fetal death, pregnant women consciously stop fetal movement, breast bloating disappears, check the uterus no longer continues to increase, weight loss, fetal heart disappear, you can consider the possibility of stillbirth. B-mode ultrasonography showed fetal movement and fetal heart disappearance, and sometimes the fetal head was deformed to confirm the diagnosis. Most stillbirths can be discharged on their own. If they are not discharged 3 weeks after death, the degenerated placenta and amniotic fluid release thromboplastin into the mother's blood circulation, causing disseminated intravascular coagulation (DIC).
