What are the causes of fetal hypoxia in late pregnancy?

People need to breathe oxygen in their environment. Many fetuses die in the mother's body due to lack of oxygen. Hypoxia has a great impact on the fetus. The smallest consequence is that the fetus will have poor quality in the future. Although there are many devices that can detect whether the fetus is hypoxic, many mothers do not know the reasons for hypoxia in their children. Let's take a look at some of the introductions made in the article:

What are the causes of fetal hypoxia in late pregnancy?

Fetal movement changes:

Fetal movement is a normal physiological activity of the fetus. Generally speaking, pregnant women can feel it between 18 and 20 weeks of pregnancy. The fetal movement varies for different fetuses. If a originally active fetus suddenly becomes quiet, or a originally quiet fetus suddenly becomes restless, and the fetal movement is less than 10 times/12 hours or more than 40 times/12 hours, there is a possibility of fetal intrauterine hypoxia. This is because the fetus is trying to reduce oxygen consumption or because hypoxia affects the central nervous system.

Pregnant women can take a sitting or lying position to count fetal movements, counting for one hour each in the morning, noon and evening (at a fixed time) every day, and multiply the sum of the three times by 4, which is the number of fetal movements in 12 hours.

Abnormal fetal heart rate:

Under normal circumstances, the fetal heart rate is regular and strong, ranging from 120 to 160 beats per minute. The husband can use simple instruments to listen to the fetal heart rate, and he should listen on the left or right side of the pregnant woman's lower abdomen, which is the side where the fetal back is located. Before the fetal movement decreases, the fetal heart rate becomes too frequent. If it exceeds 160 beats/minute, it is a sign of early fetal hypoxia. If the fetal movement decreases or stops, and the fetal heart rate is less than 120 beats/minute, it is a sign of late fetal hypoxia.

The husband should grasp the position and time to listen to the fetal heart rate and should listen at the place designated by the doctor. What needs to be noted in terms of time is that if the fetal heart rate is abnormal, it should be listened to again after 20 minutes; if the fetal heart rate is fast, it should be listened to again when there is no fetal movement.

Growth arrest:

Fetal growth becomes slowed when the fetus is deprived of oxygen. The growth of the fetus can be known by measuring the height of the uterine fundus. Pregnant women can measure it regularly at home or in the hospital. Under normal circumstances, the pregnancy should increase by about 1 cm per week after the 28th week. If there is no growth for two weeks, further examination should be carried out.

The above are the "signals" sent by fetal hypoxia. Once a pregnant woman receives an abnormal signal, she should go to the hospital for examination immediately to clearly diagnose whether the fetus is suffering from hypoxia in the uterus. Do not take it lightly or ignore it. If the fetus is confirmed to be hypoxic, the doctor will correct the cause to ensure the smooth and healthy growth of the fetus.

The above is the article's introduction to the causes of fetal hypoxia in the late pregnancy. When the fetus is hypoxic, parents must take their children to the hospital for examination in time. Only by doing a good job of the examination can the fetus be safe and grow healthily, and it can also make parents feel more at ease.
