I. Identification

It is mainly differentiated from overdue pregnancy.

Pregnancy reaches or exceeds 42 weeks, which is called overdue pregnancy. Its incidence rate is about 5 ~ 12% of the total pregnancy. The perinatal morbidity and mortality of overdue pregnancy increased, and intensified with the prolongation of pregnancy. The perinatal mortality rate at 43 weeks of pregnancy was three times that of normal. At 44 weeks, it was 5 times as normal. The risk of primipara with overdue pregnancy is increased compared with that of multiparturient. Harm to fetus and mother: 1. Fetal distress 2. Amniotic fluid volume reduction 3. Delivery difficulty and injury.

Differentiation from polyhydramnios.

Polyhydramnios can be divided into acute and chronic. Most patients' amniotic fluid increases slowly without obvious chief complaint, which is chronic polyhydramnios; If the amniotic fluid volume increases rapidly within a few days, severe abdominal distension, chest tightness, shortness of breath and inability to lie down, it is acute polyhydramnios. The incidence of chronic polyhydramnios is three times that of acute polyhydramnios. Identification points: 1. According to the medical history, whether it is overdue pregnancy. 2. B-ultrasound distinguishes macrosomia from polyhydramnios.
