For expectant mothers during pregnancy, sometimes there may be bleeding after a certain period of time. Moreover, sometimes the frequency is quite frequent and there is a lot of bleeding. This is sometimes a symptom of complete placenta previa. So, what is complete placenta previa? Let's take a look at the content that the editor has compiled for you about what complete placenta previa is.
The normal placenta attaches to the posterior, anterior, or lateral walls of the uterine body. If the placenta attaches to the lower segment of the uterus, or even the lower edge of the placenta reaches or covers the cervical opening, and its position is lower than the fetal presentation, it is called placenta previa. Complete placenta previa, also known as central placenta previa, is a type of placenta previa. The cervical opening is completely covered by placental tissue, and the clinical characteristic of placenta previa is painless and uninitiated recurrent vaginal bleeding.
When complete placenta previa occurs, the initial bleeding time is early, usually at 28 weeks of pregnancy, repeated frequently and in large amounts. Sometimes a single major bleeding can cause the pregnant woman to fall into a state of shock. B-ultrasound examination can clearly indicate the relationship between the placenta and the cervical opening with high accuracy. But if the gestational age is early and there is no vaginal bleeding during the examination, expectant therapy can be adopted, that is, regular B-ultrasound follow-up. If there is excessive vaginal bleeding, or if the pregnancy has reached 37 weeks and the examination shows that the fetus is mature, the pregnancy should be terminated by cesarean section.
The cause of placenta previa is currently unclear. The treatment principles for placenta previa are to control bleeding, correct anemia, prevent infection, and choose the right time and method to end delivery. In principle, maternal safety should be the top priority, and under the premise of maternal safety, efforts should be made to avoid premature birth of the fetus as much as possible to reduce its mortality rate.
So, if a mother planning to get pregnant, she must not have psychological pressure. Moreover, those who do not intend to have children must take protective measures to avoid unintended pregnancies and undergo abortion. Be sure to prepare for eugenics before pregnancy. Try not to let the fetus have any problems. Of course, even if there are problems during the process, we should actively face them. Follow the doctor's advice and seek active treatment.
