During the obstetric examination, I saw that the obstetric examination form said "anterior wall of the placenta" and "placenta previa". Literally, it seems to be similar, but what is the difference between the two?
More exploratory spirit of the mother-to-be will check the relevant meaning on the Internet, the result of a look, frightened, the original placenta previa is so dangerous, what to do? Then I checked a lot of solutions and marked them up to prepare for implementation. As a result, looking at the birth checklist again, it turned out that there was a oolong, and the placenta anterior wall and the placenta front were confused.
▎ Serious science popularization: what is the anterior placenta and placenta previa
Anterior placental wall: When the placenta attaches to the anterior wall of the uterus, near the side of the belly, it is called the anterior placental wall.
Placenta previa: The normal attachment of the placenta is in the posterior, anterior, or lateral wall of the uterine body. If the placenta attaches to the lower segment of the uterus or covers the inner opening of the cervix, below the fetal first exposed part, it is called placental preposition. Placenta previa is one of the main causes of bleeding in the third trimester of pregnancy and is a serious complication of pregnancy that is more common in menstruating women, especially polymopregnant women.
After pregnancy, the local blood supply is poor, and in order to obtain more nutrition, the placenta will automatically increase the area, thus covering the inner opening of the uterus and forming a placental preposition.
Although, literally, it is easier to confuse, but the former is normal and the latter is very sinister. Therefore, the expectant mother should carefully check the obstetric examination list, if there is a placenta preposition, the expectant mother should pay attention to it, and do a good job of nursing throughout the pregnancy to ensure the safety of the fetus.
▎ Hazards of placenta previa
Placenta previa can be divided into three types:
Complete placenta previa or central placenta previa: the inner cervical orifice is completely covered with placental tissue;
Partial placenta previa: the inner cervical orifice is partially covered with placental tissue;
Marginal placenta previa: the placenta attaches to the lower segment of the uterus, reaching the edge of the inner cervical opening and not beyond the inner cervical opening. The placenta is very close to the uterine orifice, which can easily cause miscarriage, and the fetus is also in danger of life at any time.
Once the intended mother is diagnosed with placenta previa after 28 weeks of pregnancy, it is considered a "high-risk pregnancy", especially the central placental preposition (the placenta completely covers the uterine opening), and the probability of premature birth and heavy bleeding after 34 weeks of pregnancy is higher.
▎How is placenta previa treated?
1. Expectant therapy
Pregnancy is less than 36 weeks, the fetus weighs less than 2300g, the amount of vaginal bleeding is not much, the pregnant woman is in good condition, and the fetus is alive, expectant therapy can be taken.
Supplemental nutrition: In fact, whether it is the placenta previa or the prewal placenta, the mother-to-be must supplement nutrition appropriately during pregnancy to ensure the good development of the fetus.
Regular obstetric examination: closely observe the condition, and at the same time carry out relevant auxiliary examinations, such as ultrasound examination, fetal maturity examination, etc., such as heavy bleeding, repeated bleeding, and terminate pregnancy as appropriate.
Prohibition of sexual life: Although it is said that AA can be performed in the second trimester, expectant mothers with placenta previa cannot have intercourse, beware of premature birth.
2. Termination of pregnancy
Aggressive measures to terminate pregnancy are required for severe hemorrhagic shock at admission, recurrent hemorrhagic shock during placental anticipatory therapy, or repeated bleeding near due date of delivery, or more bleeding after delivery. Caesarean section is the primary method of termination of pregnancy with placenta previa.
