Stillbirth

　　1. Factors related to placenta and umbilical cord

　　Such as placenta previa, abruption placenta, anterior placental insertion of umbilical cord vessels, acute chorioamnionitis, umbilical cord knotting, twisting, prolapse, and umbilical cord around the neck.

　　2. Factors related to the fetus

　　Such as severe fetal malformation, intrauterine growth retardation, intrauterine infection, genetic diseases, incompatibility of maternal and fetal blood types, etc.

　　3. Factors related to pregnant women

　　Hypertension, prolonged pregnancy, diabetes, chronic nephritis, cardiovascular disease, systemic and abdominal infections, shock caused by various reasons, etc.

　　4. Local uterine factors in pregnant women

　　Overly large uterine tension or strong contractions, uterine fibroids, uterine malformations, uterine rupture, etc., can cause local ischemia affecting the placenta and fetus.

　　5. Issues related to the birthing process

　　Fetal distress or fetal asphyxia, etc.

　　6. Environmental issues

　　Environmental toxins, drugs, etc.

　　If the stillbirth remains in the uterine cavity for too long, it can cause maternal coagulation dysfunction. If the fetus has not been delivered three weeks after death, the degenerative placental tissue releases thrombin into the maternal blood circulation, activates intravascular coagulation factors, causing disseminated intravascular coagulation (DIC), consuming fibrinogen and platelets in the blood, and other coagulation factors. The chance of DIC occurring more than four weeks after death increases significantly, which can cause severe bleeding during delivery. In addition, secondary infections and secondary infertility may also occur.

　　1. The pregnant woman feels the disappearance of fetal movement, the abdomen no longer increases in size, and the breasts become soft and smaller.

　　2. Abdominal examination shows the fundus of the uterus is smaller than the gestational age, with no fetal movement or heartbeat.

　　80% of fetal deaths occur naturally within 2-3 weeks after death

　　If the fetus has not been delivered three weeks after death, the degenerative placental tissue releases thrombin into the maternal blood circulation, activates intravascular coagulation factors, causing disseminated intravascular coagulation (DIC), consuming fibrinogen and platelets in the blood, and other coagulation factors. The chance of DIC occurring more than four weeks after death increases significantly, which can cause severe bleeding during delivery.

　　Start taking folic acid when planning to get pregnant

　　According to large-scale medical research, taking 0.4 milligrams of folic acid daily from three months before pregnancy to three months into pregnancy can reduce the risk of fetal neural tube defects (including anencephaly, encephalocele, and spina bifida) by 40% to 80%. This is one of the few preventable congenital malformations, including a method to prevent fetal death.

　　Treat the mother's diseases

　　Many chronic diseases of the mother, such as hypertension, diabetes, or thyroid abnormalities, can increase the chance of fetal death in the womb, so relevant checks should be carried out before pregnancy. If such problems are found, they should be treated first before pregnancy.

　　Avoid toxins in the environment

　　Toxins in the environment can increase the likelihood of fetal death. A report in the past indicated that in the United States, over 4,000 fetal deaths occur each year due to pregnant women smoking. Pregnant women should also avoid taking any medication without a doctor's prescription. Drugs such as heroin can also lead to fetal death. Pollutants or toxins in the environment, such as polychlorinated biphenyls and dioxins, may also cause fetal death. These situations should be avoided as much as possible. In addition, pregnant women should quit smoking and drinking, and avoid strong tea and coffee during pregnancy and before pregnancy. Pregnant women engaged in chemical production or exposure to toxic chemicals should try to change their jobs. Rural pregnant women should not spray pesticides.

　　4. Adjust work and rest, maintain a balanced diet, enhance nutrition, and keep a good mental state.

　　5. Regular prenatal examinations

　　Pregnant women should have regular prenatal examinations according to schedule, which can help identify problems early, such as gestational diabetes or gestational hypertension, and deal with them in time. This not only reduces the chance of stillbirth in the womb but also ensures the safety of the mother.

　　6. Pay attention to prenatal education.

　　1. Symptoms:According to the disappearance of spontaneous fetal movement, the abdomen no longer increases in size, the breasts become soft and shrink, if the fetal heart sound cannot be heard during examination, the uterus is smaller than the gestational age, it can be considered as stillbirth.

　　2. Examination:B-ultrasound examination, the disappearance of fetal heart and movement is a reliable basis for diagnosing stillbirth. If the death time is too long, the cranial plate may collapse, the skull may overlap, and present bag-like deformation, which can be diagnosed as stillbirth; Doppler fetal heart sound can assist in diagnosis if the fetal heart sound is not heard.

　　Differential diagnosis Ultrasound or color Doppler ultrasound examination can make an accurate diagnosis, and misdiagnosis usually does not occur.

　　In addition to those pregnant women with especially weak physique who need to eat tonics under the guidance of a doctor, pregnant women with relatively healthy physique should not eat tonics at will. Products like longan, lychee, red ginseng, deer antler, deer placenta glue, deer horn glue, and walnut meat are all tonics that help to warm the body and invigorate Yang. Excessive intake can have adverse effects on the fetus, especially in the hot summer. If it is necessary to take them, iron and ginseng can be taken in moderation to achieve a cooling blood effect.

　　Once a stillbirth is confirmed, it should be induced, and the success rate is very high. If the fetus has not been expelled three weeks after death, relevant tests of coagulation function should be performed, such as fibrinogen, platelet count, prothrombin time, etc. If the coagulation function is abnormal, medication treatment should be given, and then induce labor, and prepare fresh blood. Pay attention to prevent postpartum hemorrhage and infection, and carefully examine the placenta, umbilical cord, and fetus after delivery to find the cause of the stillbirth.
