summary

For a family, having a baby is a happy thing, but the process of giving birth to a baby is difficult, and it is easy to have an overdue pregnancy. I would like to share the relevant knowledge of overdue pregnancy with you.

What is prolonged pregnancy

First of all, when the pregnancy reaches or exceeds 42 weeks, it is called overdue pregnancy. Its incidence rate is 5% - 12% of the total number of pregnancies. The perinatal morbidity and mortality of the fetus with prolonged pregnancy increased, and increased with the prolongation of pregnancy. The perinatal mortality was three times of the normal at 43 weeks of pregnancy.

Then it was 5 times normal at 44 weeks. The risk of premature pregnancy is higher than that of multipara. The harm to fetus and mother is fetal distress, decrease of amniotic fluid volume, difficult delivery and injury.

When the last pregnancy is overdue, it has a great influence on mother and infant. Because of the pathological changes of placenta, fetal distress or fetal macrosomia cause dystocia, both of them increase the perinatal mortality and neonatal asphyxia. For the mother, because of fetal distress, cephalopelvic disproportion and prolonged labor, the operation rate increased significantly. Because of the lack of oxygen, the fetus excretes meconium, amniotic fluid, fetal skin, amniotic membrane and umbilical cord. Few children can be born smoothly. Basically, they are stillborn. The expectant mother must have more snacks.
