At what level of maturity will natural childbirth occur

The environment in which the fetus develops in the mother's uterus is very important. Along with the growth and development of the fetus, there is also the embryo. The embryo is a safe channel for the fetus and the pregnant mother to exchange nutrients. As the pregnancy progresses, the maturity of the placenta is also changing. The growth and development stage of the fetus can be seen from the maturity of the placenta. So, at what level of placental maturity can birth be possible?

How mature is the placenta before giving birth?

Generally, natural delivery can be carried out smoothly when the placenta maturity is level 1 or 2. Placental maturity level 1 indicates that the embryo is almost complete, and level 2 indicates that the embryo is already complete. It is normal for pregnant women to give birth at this time. However, if the placental maturity has reached level 3, it means that the embryo has begun to weaken, which may cause harm to the fetus. At this time, pregnant women should follow the doctor's instructions and take appropriate measures.

Placenta thickness

1. The normal B-ultrasound placental thickness is 3.6-3.8 cm, generally not exceeding 5 cm.

2. The characteristic of a film-like embryo is that the total area of ​​the embryo is large and thin, and it is easy to bleed in the middle and late stages of pregnancy. If the embryo is small, it may cause delayed language development in the fetus and low birth weight at full term.

In fact, simply looking at the thickness of the placenta does not have much practical significance. If there are no other problems during the prenatal check-up, there is basically no need to worry.

In addition, placental thickness and placental maturity are two different concepts. If the placenta is too mature, it should be a cause of alarm.

The nutrients needed for the baby's development are all obtained through the embryo, so the quality of the placenta's function directly affects the health of the fetus. Pregnant mothers should be alert to problems such as placental insufficiency to avoid fetal malnutrition or fetal hypoxia.

What does placental maturity mean?

The embryo will gradually mature as the pregnancy progresses. When it matures to a certain level, its function will immediately decrease, just like aging, and it will not be able to provide nutrients and oxygen to the fetus normally. The placental maturity level classification is a standard used to measure the maturity of the placenta, which is generally divided into 4 levels, as follows:

There are four levels of placental maturity: 0, 1, 2, and 3.

Grade 0 indicates that the embryo is not yet complete: usually in the middle and late stages of pregnancy, around 12-28 weeks of pregnancy.

Level 1 indicates the early stage of placental maturity: 30-32 weeks of pregnancy, the early stage of placental maturity, can deliver nutrients to the fetus.

Level 2 indicates that the embryo is already complete: generally after 36 weeks of pregnancy, the embryo is close to the uterus.

Level 3 indicates that the embryo has declined. Due to the thickening and cellulose accumulation, the embryo's ability to transport oxygen and nutrients is reduced, and the fetus is at risk at any time.

The maturity of each person's placenta is different: in the middle and late stages of pregnancy (12-28 weeks) - placenta level 0; in the late stages of pregnancy (30-32 weeks) - embryonic level 1; after 36 weeks - embryonic level 2 (more complete). If the embryo is found to be grade 3 before 37 weeks and combined with the value of the biparietal diameter and the estimated baby weight is 2500 grams, the embryo maturity should be considered and the possibility of intrauterine growth and development delay of the fetus should be alerted. At 38 weeks, the embryo reaches stage 3, indicating that the placenta is mature.
