Symptoms of hypoxia in late pregnancy

summary

During pregnancy, a series of changes have taken place in pregnant women's body, not only the diet increases, the nutritional needs are more, and the oxygen consumption of the body is about twice that of ordinary people. Therefore, the poor physical quality of pregnant women, or the long-term stuffy air environment will produce symptoms of hypoxia, such as anemia of pregnant women, long-time shopping in supermarkets, crowded bus and so on. Late pregnancy symptoms of hypoxia to talk to you.

Symptoms of hypoxia in late pregnancy

Anemia is also an important factor of hypoxia in pregnant women. With the increase of gestational age, the blood volume of pregnant women increases, and the blood is relatively diluted; The growth and development of the fetus, such as the growth of muscle and bone, need to absorb a lot of iron, which undoubtedly needs to be obtained from the mother. It needs to consume a lot of hemoglobin from the mother, and the lack of oxygen carried by the mother leads to fetal hypoxia.

Timely and regular oxygen supplement can not only prevent various symptoms of hypoxia, but also help to stabilize the fetus, protect the fetus, and effectively improve the infant's intelligence and development ability. Maternal hypoxia will directly affect the fetal body, brain, mental retardation, premature delivery and even stillbirth. Pregnant mothers must be paid attention to.

Symptoms of fetal hypoxia: change of fetal movement, abnormal fetal heart sound, growth retardation, sudden acceleration of fetal movement, or sudden deceleration of fetal movement, if the fetal movement is less than 10 times / 12 hours or more than 40 times / 12 hours, it indicates that fetal intrauterine hypoxia is possible.

matters needing attention

Pregnant women take sitting or lying position, pay attention, put paper and pen beside them to record, and press hands on abdomen to experience fetal activities. The time from the beginning of fetal activity to the end of fetal movement is one time, three times a day, one time in the morning, one time in the middle and one time in the evening, one hour each time. The time is relatively fixed. The cumulative number of fetal movements in a day is three hours, and then multiplied by four to get the number of fetal movements in 12 hours. If the number of fetal movements in one hour is less than 3 times, the number of fetal movements in 12 hours is less than 10 times, or the number of fetal movements is increased or decreased by more than 50% compared with the previous days, it indicates that the fetal intrauterine condition is poor, so we should go to the hospital immediately.
