Fetal distress is called fetal distress when there are signs of hypoxia in the fetus, which endanger the health and life of the fetus. Once pregnant women find that the fetus has hypoxia symptoms such as abnormal fetal heart rate, fetal movement change and growth stagnation, they should go to the hospital in time to make a clear diagnosis of intrauterine hypoxia, so as to correct the cause and ensure the smooth and healthy growth of the fetus.
The causes of fetal distress can be summarized into three categories:
1, maternal factors and maternal oxygen deficiency are important reasons. For example, the mother suffers from pregnancy-induced hypertension, severe anemia, carbon monoxide poisoning, shock caused by various reasons, acute infection and fever.
2, placenta, umbilical cord factors, umbilical cord transportation is blocked, such as umbilical cord is too long, too short, umbilical cord winding, knotting, kinking, placental function is low.
3, fetal factors, the fetus suffers from serious congenital cardiovascular disease, intracranial hemorrhage, fetal malformation and so on. Fetal distress mainly occurs during labor, but also in the third trimester of pregnancy. If the fetal movement decreases at the 37th week of pregnancy, there will be chronic fetal distress, which often lasts until labor and gets worse. Such patients should do the following tests: placental function determination, fetal heart monitoring, fetal biological score, fetal movement count. If the fetal condition is acceptable, we should take a rest in the left lateral position and take regular oxygen inhalation to improve the placental blood supply. If the fetal hypoxia is difficult to improve and close to full term, it is estimated that there is a great chance of fetal delivery, and cesarean section can be considered to terminate pregnancy.
