What are the causes of fetal death?

Pregnancy is undoubtedly a very happy thing for any couple or a family, but pregnancy does not mean that the baby can come to this world in good health, sometimes the baby dies in the womb, just like Ronaldo's family also has this situation, we will feel sorry. So, what are the causes of fetal death, I summarize the following.

1. Fetal chromosomal abnormalities are the main reason, genetic diseases can cause embryonic gene mutations, chromosomal abnormalities, can cause fetal malformations, miscarriages, and even stillbirths.

2. Genetic aberration, intrauterine infection of the fetus in the first trimester, the use of teratogenic drugs during pregnancy, or exposure to toxic substances and radiation can lead to genetic mutations and chromosomal aberrations of the fetus, resulting in fetal death in utero.

3. Fetal intrauterine hypoxia, which is the most common factor causing fetal death, 50% of stillbirths are caused by fetal intrauterine hypoxia, such as placental dysfunction, umbilical cord knotting, umbilical cord torsion, fetal severe malformations, pregnancy complications and infections, multiple pregnancies, are the causes of stillbirth.

4. Placental factors, such as placental infarction or placental abruption and placental hemorrhage, will affect the blood flow of the placenta, and then lead to fetal death.

5. There may be hypertensive diseases during pregnancy, which seriously affect the blood flow of the fetus, which will lead to intrauterine growth retardation of the fetus, and in severe cases, intrauterine death of the fetus.

6. There may be gestational diabetes, if the blood sugar is not well controlled, it will cause sudden stillbirth.

7. Childbirth process. Special attention should also be paid during the production process, which may also cause fetal distress or suffocation, resulting in stillbirth. This condition generally occurs when the fetus is too large, the delivery time is too long, and it stays in the birth canal for too long, and it has not been able to give birth.

In the production process, a series of situations such as improper force may cause stillbirth.

8. Early water breakage. If the amniotic fluid breaks early due to various reasons, it is easy to cause infection in the uterus, and if the infection is severe, it is likely to lead to stillbirth.

If the death of the fetus in the womb of a pregnant woman does occur, there will be a series of symptoms, the more typical symptoms are:

1.Normally, a pregnant woman's uterus will continue to grow larger, but when the baby is stillborn in the womb, the uterus of the pregnant woman will stop enlarged.

2.A normal-growing fetus will have "movements". However, if the fetus dies in the womb, the fetal movement will stop and the fetal heartbeat will naturally not be heard.

3.After the death of the fetus, the pregnant woman will also feel uncomfortable, such as lack of eating, physical exhaustion, and stomach pain.

Therefore, after pregnancy, you must check on time, once there is a physical disease, it is best to pay attention to conditioning and reduce the impact according to the physical condition, and at the same time try to achieve a balanced nutrition in terms of diet, do not overeat, try not to eat too greasy.

What are the causes of fetal death?

According to the World Health Organization, the number of high-risk pregnancies in women over the age of 35 is increasing, which directly threatens the health of mothers and babies。The older the mother, the higher the chance of developing gestational hypertension, gestational diabetes, postpartum depression, etc. Combined with social, psychological and other factors, the first period of childbirth is 25 to 30 years old, and women are physically and mentally mature at this stage, which is suitable for conceiving babies.

How can neonatal intracranial hemorrhage be prevented?

1. First of all, regular prenatal checkups. If it is a pregnant mother with diabetes, it should be active to prevent the birth of macrosomia or cramps caused by hypoglycemia and cause fetal brain damage.

2. Secondly, at the end of pregnancy, it is necessary to avoid overwork, but also to avoid abdominal trauma to prevent the appearance of premature infants.

3. Thirdly, it is necessary to prevent fetal hypoxia during childbirth, and try not to use oxytocin or drugs that suppress the central nervous system. Finally, premature infants, surgical births, and newborns with asphyxia during childbirth should be given special care and intramuscular vitamin K injection after birth to prevent intracranial hemorrhage. In addition, it should also be noted that if there is a possibility of dystocia in pregnant women, it is also necessary to pay attention to appropriately relaxing the indications for caesarean section to prevent birth injury.

The causes of fetal death can be divided into three aspects: fetal, placental umbilical cord and maternal. 1. Fetal factors: Up to 25 to 40 percent of stillbirths are caused by fetal diseases, such as neural tube malformations or complex congenital heart disease and other fatal structural abnormalities, chromosomal abnormalities such as trisomy 21-45x, intrauterine infection, and intrauterine growth retardation.

2. Placental umbilical cord factors: about 25%-35% of stillbirths are caused by placenta or umbilical cord factors, such as placental abruption, vasa previa, placenta previa, post-term pregnancy, etc., various factors can lead to placental function damage, umbilical cord abnormalities such as umbilical cord knotting or entanglement, umbilical cord prolapse, etc. In addition, twin transfusion syndrome is the leading cause of death in monochorionic twins.

3. Maternal factors: Pregnancy complications and complications, such as pregnancy hypertension syndrome, diabetes mellitus, connective tissue disease, pregnancy intrahepatic cholestasis, antiphospholipid syndrome, hereditary thrombophilia, red blood cell allogeneic immunization and platelet allogic immunization, etc., can lead to stillbirth. In addition, shock or uterine rupture caused by various causes and ischemia can also cause stillbirth.

Pregnant women who are overweight or obese and who are too young or too old at birth can also significantly increase the risk of stillbirth.

Placental umbilical cord factors:

About 25%-35% of stillbirths are caused by placental or umbilical cord factors, such as placental abruption, vasa previa, placenta previa, overdue pregnancy, etc., various factors can lead to placental function damage, umbilical cord knotting or entanglement and other umbilical cord abnormalities, umbilical cord prolapse, etc. In addition, twin transfusion syndrome is the leading cause of death in monochorionic twins. 3. Maternal factors:

Pregnancy complications and complications, such as pregnancy-induced hypertension, diabetes, connective tissue disease, pregnancy intrahepatic cholestasis, antiphospholipid syndrome, hereditary thrombophilia, red blood cell allogeneic immunization and platelet alloginomy, can lead to stillbirth. In addition, shock or uterine rupture caused by various causes and ischemia can also cause stillbirth. Pregnant women who are overweight or obese and who are too young or too old at birth can also significantly increase the risk of stillbirth.
