What causes fetal hypoxia, and how is fetal hypoxia caused?

Fetal intrauterine hypoxia may lead to fetal growth retardation, that is, fetal intrauterine growth restriction, and severe fetal intrauterine hypoxia may also lead to fetal death in utero or fetal intrauterine distress. Fetal intrauterine hypoxia is mainly related to insufficient oxygen content in maternal blood, impaired blood oxygen transport or exchange between mother and fetus, and abnormal fetal factors. Fetal intrauterine hypoxia is divided into acute hypoxia and chronic hypoxia, and acute hypoxia is often caused by blood circulation disorders in the uterus and placenta, obstruction of gas exchange or disorders of blood circulation in the umbilical cord.

For example, placenta previa, placental abruption, excessive contractions or excessive twisting of the umbilical cord, true umbilical cord knot, or umbilical cord prolapse. Chronic fetal hypoxia is often related to insufficient blood oxygen content of the fetus and vascular lesions of the uterus and placenta. ”

Every pregnant mother hopes that her baby can come to the world safely, but many factors in life will affect the healthy growth of the fetus. Especially in the third trimester, some of the living habits of the pregnant mother are closely related to the fetus, and if you do not pay attention, it may lead to the "lack of oxygen" of the fetus, which seriously threatens his life. Therefore, the four elements mentioned in the article must be paid attention to by expectant mothers.

What are the symptoms of fetal hypoxia?

How about fetal hypoxia**?

The cause of fetal hypoxia is that the oxygen content in the mother's blood is insufficient, resulting in a disorder of blood oxygen exchange between the pregnant woman and the fetus, and the fetus's own factors may lead to fetal hypoxia.

There are many causes of fetal hypoxia, such as maternal factors, blood oxygen transport and exchange disorders between the mother and fetus, placental hypofunction, such as placenta previa, placental abruption, placenta too large or too small, umbilical cord abnormalities and fetal factors can cause fetal hypoxia. If there is a lack of oxygen in the fetus, the mother must pay attention to the observation at ordinary times, and the abnormal situation should be treated in the hospital as soon as possible.

Fetal hypoxia is mainly caused by the umbilical cord around the neck, resulting in fetal respiratory distress and insufficient oxygen uptake, which is very dangerous.

"The main causes of fetal hypoxia are the low oxygen content of the mother's blood, the impaired blood oxygen exchange between the mothers, and some of the fetus's own factors. These causes can lead to fetal hypoxia manifestations, which are divided into acute and chronic hypoxia. If it is an acute hypoxia.

Causes include placental abruption, compression of umbilical cord prolapse, and frequent contractions due to inappropriate oxytocin use. Overdose of anesthetic and sedative drugs can also lead to acute hypoxia. In the case of chronic hypoxia, it occurs in the third trimester.

It may be that the maternal anemia leads to insufficient oxygen content, or the pregnant woman has gestational hypertension, or the fetus has severe cardiovascular malformations, placental necrosis, vascular degeneration and other problems. ”

There are many cases of fetal hypoxia in utero**, the most common is the placenta, followed by the umbilical cord**, and it may also be the woman's own ** during pregnancy**, insufficient oxygen content in the maternal blood, blood oxygen exchange disorders between the mother and fetus, and fetal factors can lead to fetal hypoxia.

The cause of fetal hypoxia is caused by the congenital development factors of the fetus itself, such as the abnormal function of the fetal congenital organs, or the problem of umbilical cord around the neck, the abnormal growth of the placenta or the problem of amniotic fluid volume, which is the maternal factor, on the other hand, the mother suffers from some serious complications will also easily lead to fetal hypoxia, the oxygen required by the fetus is obtained from the mother, when the blood oxygen content of the pregnant woman is insufficient, or there is a problem with the blood exchange between the fetus, This will cause the fetus to be deprived of oxygen. For example, pregnant women have bad smoking and drinking habits, severe anemia, low blood pressure, gestational diabetes, etc., which will lead to hypoxia.
