During the maternity check-up, we saw the words “anterior wall of placenta” and “placenta previa” on the maternity check-list. Literally, it seems almost the same, but what is the difference between the two?

Mothers-to-be who are more exploratory will go online to check the relevant meanings on their own, and the results show that they are frightened, because the placenta previa is so dangerous, what should we do? Then I looked up a lot of solutions and marked them up for implementation. Result Look at the production inspection list again, the original Oolong ah, the placenta anterior wall and placenta anterior confusion.

Serious popular science: what is anterior placenta and placenta previa

The anterior wall of the placenta: When the placenta attaches to the anterior wall of the uterus, it is called the anterior wall of the placenta when it is near the belly.

Placenta previa: The normal attachment of the placenta is on the posterior, anterior or lateral wall of the uterine body. If the placenta attaches to the lower part of the uterus or covers the cervical orifice, it is lower than the fetus’s anterior part, which is called placenta previa. Placenta previa is one of the main causes of bleeding in the third trimester of pregnancy. It is a serious complication during pregnancy. It is often seen in multipartum women, especially in multipartum women.

After pregnancy, the local blood supply is poor. In order to get more nutrition, the placenta will automatically enlarge the area, thus covering the uterine mouth, forming the placenta previa.

Although it is easy to confuse literally, the former is normal and the latter is very dangerous. Therefore, expectant mothers should carefully check the birth check list. If placenta previa occurs, expectant mothers should pay attention to it. They should do a good job of nursing during the whole pregnancy to ensure the safety of their babies.

The harm of placenta previa

The placenta previa can be divided into three types:

Complete placenta previa or central placenta previa: all cervical internal orifices are covered by placental tissue;

Partial placenta previa: The inner cervical orifice is covered by placenta tissue.

Marginal placenta previa: The placenta attaches to the lower part of the uterus, reaching the edge of the cervical internal orifice, not beyond the cervical internal orifice. The placenta is very close to the uterine mouth, which can easily lead to abortion, and the fetus is at risk of life at any time.

Once the mother-to-be is diagnosed with placenta previa after 28 weeks of pregnancy, it will be considered as a “high-risk pregnancy”, especially central placenta previa (placenta completely covering the uterine orifice), which has a higher risk of premature delivery and massive bleeding after 34 weeks of pregnancy.

How to treat placenta previa?

1. Expectation therapy

Pregnancy less than 36 weeks, fetal weight less than 2300g, vaginal bleeding volume is not much, pregnant women in good condition, fetal survivors, can take anticipated therapy.

Supplementary nutrition: In fact, whether it is placenta previa or placenta anterior wall, expectant mothers should be properly supplemented during pregnancy, in order to ensure the good development of the fetus.

Periodic obstetric examination: closely observe the condition, and carry out relevant auxiliary examinations, such as B-mode ultrasonography, fetal maturity examination, such as massive bleeding, repeated bleeding, termination of pregnancy as appropriate.

Prohibited Sexual Life: Although AA can be used during the second trimester of pregnancy, prospective mothers with placenta previa can not have sexual intercourse, so beware of premature birth.

2. Termination of pregnancy

Positive measures should be taken to terminate pregnancy, such as massive hemorrhagic shock at admission, massive hemorrhagic shock in placenta previa anticipation therapy, recurrent hemorrhage near the expected stage of delivery, or more postpartum hemorrhage. Cesarean section is the main way to terminate pregnancy with placenta previa.
