How to know fetal intrauterine hypoxia?

summary

Expectant mothers often do prenatal care, because expectant mothers are very concerned about the health of the fetus. Many expectant mothers want to know the symptoms of fetal abnormalities in advance, such as the symptoms of fetal intrauterine hypoxia. Next, let's see how expectant mothers know the manifestations and symptoms of fetal intrauterine hypoxia.

How to know fetal intrauterine hypoxia?

In the early stage of hypoxia, the fetus will send out a signal for help, and their performance is "losing temper", which should be paid attention to by pregnant women. When the fetal movement is less than 4 times / hour, we should pay attention to the possibility of fetal death. Observation of fetal movement, fetal heart rate no acceleration response, or no fetal movement, that is no response type. Sometimes even spontaneous deceleration of fetal heart rate occurs. Contractile stress test can be positive.

After intrauterine hypoxia, fetal growth will be slow, fetal growth can be measured by the height of the uterine fundus (distance from the top of the pubic symphysis to the highest part of the uterine fundus). Under normal circumstances, after 28 weeks of pregnancy should be increased by about 1 cm per week. Pregnant women can be measured regularly at home or in the hospital, if it does not increase for 2 weeks, further examination should be done.

Fetal movement is one of the vital signs of the fetus, which can be used to understand the safety of the fetus in the uterus. It is also a good method for pregnant women to self-monitoring, and its reliability is more than 80%. Under normal circumstances, fetal movements should not be less than 3 times per hour, 12 hours should not be less than 30 times. If the fetal movement increases sharply and becomes frequent and intense after labor, it indicates that the fetus may have acute distress, which is mostly caused by acute hypoxia caused by umbilical cord compression and placental abruption. If the number of fetal movements on the same day is reduced by 30% or more than before, it means that the number of fetal movements is reduced. Once the fetal movement disappears, the fetus may die at any time, and the time of death is mostly 12-72 hours after the disappearance of fetal movement.

matters needing attention

Fetal hypoxia is the main cause of fetal death, maternal abdomen, neonatal infection or premature death and children's mental retardation. Although many modern instruments and equipment can monitor fetal hypoxia, it is difficult for pregnant women to receive medical monitoring from time to time, so some fetal hypoxia can not be detected and corrected in time. Pregnant women should have regular prenatal examination to estimate that the fetal condition is OK. They should be asked to take more lateral position to rest, so as to improve the placental blood supply and prolong the gestational weeks. If the fetal intrauterine hypoxia is difficult to improve and close to full-term pregnancy, it is estimated that there is a great chance for the fetus from bottom to top after delivery. In order to reduce the impact of uterine contraction on the fetus, cesarean section is feasible.
