What is prolonged pregnancy

summary

The occurrence of prolonged pregnancy is very unfortunate, which not only affects the safety of the fetus, but also threatens the life safety of pregnant women. Let's take a look at what is an overdue pregnancy.

What is prolonged pregnancy

First: pregnancy reaches or exceeds 42 weeks, which 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.

Secondly, 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.

Finally: the cause of the late pregnancy is not clear. Because there are many possible factors leading to childbirth, including progesterone block, oxytocin stimulation and fetal adrenal cortical hormone secretion, any factor causing these hormone imbalance can lead to prolonged pregnancy. It is very important to understand the cause of the disease and avoid this serious situation.

matters needing attention

Some pregnant women think that they are mature and unwilling to accept the method of artificial termination of pregnancy. They should actively do the work of pregnant women, do not have any illusions, and terminate the delivery as soon as possible to prevent accidents.
