What happens if the fetus is born without oxygen?

Some pregnant women often experience unexpected situations during the critical period of delivery. During delivery, fetal hypoxia is a very serious condition. Severe cases can lead to life-threatening situations, so pregnant women should always pay attention to changes in their bodies. Pay attention to the changes of the fetus in the body, and prenatal check-ups actually need to be done in a timely manner. In addition, in the later stages of pregnancy, you should pay attention to regularly measuring the fetal heart rate. What happens if the fetus is deprived of oxygen after birth?

What happens if the fetus is born without oxygen?

The brain is an organ that is most sensitive to ischemia and acidosis. There are many factors that cause brain damage, and fetal hypoxia is one of them. Ischemic and hypoxic encephalopathy is the most serious complication of fetal distress. There are two types of brain tissue damage caused by fetal hypoxia: the first is functional damage. Long-term follow-up of fetuses with mild or chronic fetal distress and fetal growth restriction shows that their subsequent intellectual development is lower than that of normal fetuses. The second is organic damage. In severe brain hypoxia, it is easy to cause complications such as cerebral edema, brain cell necrosis, and cerebral hemorrhage, which is called ischemic and hypoxic encephalopathy. If fetal hypoxia is treated promptly and recovered, and only temporary damage is caused to the fetal brain, the fetus will recover in about a week of treatment. If the fetus is deprived of oxygen for a long time, the brain cells in the fetus will be deformed and necrotic, and it will be difficult to recover in the short term. In more serious cases, permanent brain damage will occur.

How pregnant women can prevent their babies from lack of oxygen

Regular electronic fetal heart rate monitoring, B-ultrasound examinations, and fetal-placental function testing can help detect fetal intrauterine hypoxia in a timely manner and ensure timely delivery. Around 36 weeks of pregnancy is a high incidence period of intrauterine growth retardation and fetal death, so monitoring should be strengthened; in addition, pregnant women should not sit for too long. Because the sitting posture will compress the uterus and is not conducive to the movement of the fetus in the abdomen. Over time it will affect the blood circulation of the placenta, and then cause fetal hypoxia. Pregnant women should walk more appropriately, which is not only good for the fetus, but also helps to raise the head and lower it, which will be more conducive to normal delivery during delivery; being overweight or exposed to secondhand smoke in pregnant women can also reduce the amount of oxygen supplied to the fetus during pregnancy.
