Fetal hypoxia, how will pregnant women react and how to avoid it?

Acute or chronic hypoxia in uterus endangers the health and life of fetus, which is called fetal distress in medicine. Acute hypoxia mostly occurs in the delivery period, and chronic hypoxia mostly occurs in the third trimester of pregnancy. Fetal hypoxia may lead to fetal growth restriction, permanent brain damage, and even fetal death in utero.

Q 1, fetal hypoxia, how does pregnant mother react? Abnormal fetal movement is an important feeling to remind pregnant mothers of intrauterine hypoxia! In acute fetal hypoxia, fetal movement is frequent at first, then weakened, the number of times decreased and finally disappeared; For chronic fetal hypoxia, fetal movement is characterized by reduction or disappearance of fetal movement. Some pregnant mothers, especially new mothers, may be full of questions: What is fetal movement? I can't calculate fetal movements.

Pregnant mothers can generally feel fetal movement around 20 weeks of pregnancy. You can feel it when the baby in the belly reaches out and kicks around in the uterus and impacts the uterine wall. Under normal circumstances, 1 hour fetal movement is not less than 3 ~ 5 times. Generally, fetal movement will be more active after meals, afternoon and evening, and will disappear in a short time due to the influence of fetal sleep cycle, and the disappearance can last for 20~40 minutes. After 28 weeks, if the fetal movement count is less than 10 times /2 hours or 50% lower than usual, it indicates the possibility of fetal hypoxia. Counting fetal movement is a simple, economical and effective method for pregnant mothers to self-evaluate the intrauterine situation. Now some pregnant mothers use some apps on their mobile phones to count fetal movements, which is much more convenient.

Q2。 How to avoid fetal hypoxia? In order to avoid fetal hypoxia, pregnant mothers and medical staff need to work together to prevent this from happening.

For pregnant mothers

1. Routine physical examination can be done before pregnancy, especially for women with congenital heart disease, asthma or family history of such diseases, and whether cardiopulmonary function can tolerate pregnancy can be evaluated in advance; And rule out anemia.

2. For some diseases found before or during pregnancy, such as hypertensive disorder complicating pregnancy, diabetes, chronic nephritis, connective tissue disease, etc. It is necessary to control related diseases before or during pregnancy so as not to affect placental function.

3. Regular examination during pregnancy, especially B-ultrasound, plays an important auxiliary role in evaluating fetal development and umbilical blood flow.

4. Learn to count fetal movements in the third trimester, but fetal movements are subjective and individual after all. If fetal movement is reduced or abnormal, you need to see a hospital in time and be evaluated by an obstetrician.
