About placental maturity

　　placental maturity

　　There are four levels of placental maturity: Level O, Level 1, Level 2 and Level 3. Level 1 sign means the placenta is basically mature ； Grade 2 lateness marks placental maturation ； Grade 3 late indicates that the placenta has aged. Due to calcification and cellulose deposition, the placenta’s ability to transport oxygen and nutrients is reduced. fetus There is always danger.

　　The placenta is different for everyone: second trimester (12-28 weeks) - placenta grade 0； Third trimester of pregnancy (30-32 weeks)—placenta level 1 ； After 36 weeks - placenta grade 2 (relatively mature). If placenta grade 3 is found before 37 weeks combined with the value of biparietal diameter and an estimated fetal weight of 2500 grams, this may be premature placenta, and you need to be alert to the possibility of intrauterine growth retardation. The placenta enters level 3 at 38 weeks, indicating that the placenta is mature.

　　Doctors use ultrasound to determine the maturity of the placenta, mainly through the calcification spots on the placenta. If the calcification points are scattered, it will be diagnosed as level 2, and if the calcification points are connected into pieces, it will be diagnosed as level III. This will be affected to some extent by subjective factors. Some doctors may think it is level 3, but some doctors can only reach level 2.
