The harm of placental aging at 35 gestational weeks?

summary

A few days ago, I went to the pregnancy check-up. It's already a week past the expected delivery date. I went to the hospital to have a check-up. The doctor suggested that I should be hospitalized. It's aging and too much. But my mother-in-law always said that it's OK to go again when she has severe stomachache. I've been waiting for her to go as early as possible. I also understand that, but if the child has any problems, who should I blame? The harm of placental aging at 35 gestational weeks?

The harm of placental aging at 35 gestational weeks?

To measure whether the function of a placenta is decreased, which is often called "placenta aging", mainly depends on whether the development maturity of the placenta exceeds the month of pregnancy. Usually, when most pregnant women are near term, the placenta maturity is in grade II and III, which is very normal. However, if the gestational age is about 20 weeks, the placental maturity will reach grade II, or about 35 weeks, the placental maturity will reach grade III, which indicates that the placental function is decreased. Due to the decrease of oxygen and nutrients from the mother to the fetus, the placenta may cause intrauterine hypoxia, which not only affects the growth and development of the fetus, but also is life-threatening.

The so-called placental aging refers to the decline of the role of the placenta, which results in fetal hypoxia, malnutrition, growth retardation and fetal distress, even stillbirth, stillbirth, neonatal asphyxia, etc. its long-term consequence is to cause fetal brain cell necrosis, dysplasia, and eventually into mentally retarded children.

In fact, prolonged pregnancy is the most common cause of placental aging. At this time, placental dysfunction, its material exchange capacity, far from meeting the needs of the fetus has increased, will lead to fetal distress and endanger the fetus. The causes of placental aging are: pregnant women with previous pregnancy, chronic nephritis, diabetes or hypertension; Pregnant women have cardiopulmonary disease and severe albumin oxygen deficiency; Because of improper. In addition, maternal diseases, congenital placental dysplasia and fetal malformations can also cause placental dysfunction and premature aging.

matters needing attention

When the function of placenta is low, it will affect the material exchange capacity of placenta, directly affect the oxygen supply of fetus, easily lead to fetal distress, and endanger the health and safety of fetus. Therefore, if placental aging is found, close monitoring should be paid attention to, and if necessary, induction of labor or cesarean section should be taken to terminate pregnancy.
