How to check fetal intrauterine hypoxia?

We know that a normal person needs to live in an aerobic state, that is, a person needs to have certain biological reactions such as gas exchange with the outside world. For the unborn fetus, it is equally important to exchange gas with the outside world, that is, oxygen is indispensable in the uterus. So, how to check the fetal intrauterine hypoxia?

There are many things that need to be paid attention to when checking fetal hypoxia after pregnancy, so expectant mothers must pay more attention to it in peacetime, so how to judge fetal hypoxia? If these phenomena occur, it is that your baby sent you a distress signal!

How to check fetal hypoxia? Fetal hypoxia, that is, fetal (intrauterine) distress, is one of the highest perinatal mortality factors and one of the indications of cesarean section. Fetal hypoxia is so harmful to people's body and mind, so how to judge whether the fetus is hypoxic in clinic? What inspection should fetal hypoxia do? You can check by the following methods:

1. Listen to the fetal heart rate.

In the case of insufficient oxygen, the fetal heart contracts more violently, and more blood needs to be "pumped" to extract the necessary oxygen. After 0/8-20 weeks of pregnancy, the fetal heart beats at the rate of 140- 160HR per minute.

2. Electrocardiogram (CTG)

The contraction frequency of uterus and the heart rate of fetus can be measured simultaneously.

3. Doppler (that is, ultrasonic examination)

The diagnosis is made by examining the blood circulation of uterine wall and fetal blood vessels.

Causes of fetal intrauterine hypoxia When the fetus is in the mother's stomach, the mother can directly observe the baby's condition, so sometimes the mother doesn't know about the baby's abnormal situation, so what will happen to the baby's hypoxia? First of all, we can look at the abnormal fetal movement, second, the situation of fetal heart, and third, the situation that the fetus stops developing. There are several reasons that may lead to intrauterine hypoxia:

1, parent factor

The oxygen needed by the fetus comes from the mother and is exchanged through the placental villus space. Lack of oxygen in the mother's blood can lead to fetal hypoxia. High-risk pregnancy, maternal acute blood loss and severe anemia, fever caused by acute infection, excessive use of anesthetics and sedatives by pregnant women to suppress breathing, excessive uterine contraction caused by improper use of oxytocin, prolonged labor, premature rupture of membranes, smoking and passive smoking. Excessive mental stress of pregnant women leads to sympathetic nerve excitation, vasoconstriction, insufficient blood supply to placenta, and long-term supine position, which easily leads to insufficient oxygen content in maternal blood.

2. Obstacles in blood oxygen transport and exchange between mother and fetus.

Placental dysfunction, such as overdue pregnancy, placenta previa, placental abruption, placenta oversize or undersize, membranous placenta, contour placenta, etc. Umbilical cord abnormalities, such as umbilical cord around the neck, umbilical cord knotting, umbilical cord torsion, umbilical cord prolapse, umbilical cord hematoma, umbilical cord too long or too short, umbilical cord attached to fetal membranes, etc.; Excessive expansion and contraction of uterus can easily lead to fetal hypoxia.

3. Fetal factors

Fetal cardiovascular system dysfunction, such as severe congenital cardiovascular disease and intracranial hemorrhage, fetal malformation, maternal and infant blood group incompatibility, intrauterine infection, craniocerebral injury and other reasons will lead to fetal hypoxia.
