Placenta previa cesarean section for several months

Placenta previa cesarean section for several months

Placenta previa refers to a growth and development site of the embryo. Generally speaking, the possibility of a normal birth for embryos in this area is relatively small. Once placenta previa occurs, many symptoms that are unfavorable for choosing natural delivery will appear, and many abnormal conditions of the human body will occur. So, at how many months should a caesarean section be performed for placenta previa?

36~37 weeks.

Pregnant women with placenta previa are generally considered to have given birth after a cesarean section. For placenta previa without vaginal bleeding, the gestational age should be increased as much as possible until the pregnancy is terminated after full term. If there is a small amount of vaginal bleeding, a complete placenta previa can be delivered by cesarean section after 36 weeks of pregnancy, and a partial placenta previa can be delivered by cesarean section after 37 weeks of pregnancy. For those with heavy vaginal bleeding and immature fetal lungs, the pregnancy can be terminated after promoting lung development in a short period of time.

Once placenta previa causes severe bleeding and seriously endangers the life safety of the pregnant woman, a caesarean section should be performed immediately regardless of the gestational age.

Why is cesarean section used for placenta previa

Due to placenta previa, there is a risk of internal bleeding as soon as the cervix is ​​opened through natural delivery. Caesarean section will be safer and can immediately complete the delivery of the pregnant woman, achieve the purpose of rapid blood circulation, reduce trauma to the fetus, reduce perinatal morbidity, and solve postpartum hemorrhage under supervision. Cesarean section is the safest and most effective way to solve placenta previa, and it is also the emergency treatment method for severe bleeding caused by placenta previa.

How to treat placenta previa

Hope Therapy

If placenta previa occurs, the pregnancy is less than 34 weeks and the weight of the fetus is less than 2.3kg. If the pregnant mother has little vaginal bleeding and is in good general condition, she can use hopeful treatment to inhibit uterine contractions and promote fetal lung development. During this period, pregnant mothers need to stay in bed and rest, and the actual treatment method should follow the doctor's treatment plan.

Termination of pregnancy

If the placenta previa is severe and there is internal bleeding shock during hospitalization, or repeated bleeding in the near-delivery period, or heavy bleeding after delivery, active measures must be taken to terminate the pregnancy.

What are the harms of placenta previa

1. Bleeding during and after delivery. After delivery, the muscles in the lower uterus are weak, and the attached embryo is not easy to separate. Even after separation, postpartum bleeding is more likely to occur because the open blood sinuses are not easy to close.

2. Anemia and infection. Most pregnant women suffer from anemia due to repeated bleeding, have a weak constitution, and the placenta previa detaches from the internal os of the cervix, so they are very prone to infection during the confinement period.

3. Implanted embryo. Placenta previa can sometimes be combined with placenta accreta, resulting in incomplete placental separation and internal bleeding, and sometimes the uterus needs to be removed in order to save the life of the pregnant woman.

4. Poor perinatal prognosis. Excessive bleeding can cause fetal distress or even death from lack of oxygen. Sometimes, in order to save the life of the pregnant woman or the fetus, the pregnancy must be terminated early, resulting in an increase in the rate of premature birth.
