The central type of placenta praevia is detected in the 6th month of pregnancy, and when there are no abnormal symptoms, bed rest can be expected to be treated, and painless recurrent vaginal bleeding can be treated with fertility preservation or termination of pregnancy can be dealt with. After 28 weeks of pregnancy, the lower edge of the placenta completely covers the opening of the cervix as central placenta previa, which is one of the more serious types of placenta previa. The central placenta previa is detected in the sixth month of pregnancy, when the placenta still has the possibility to grow up. Normally, you should mainly rest in bed and reduce some actions that increase the pressure on the abdomen, such as avoiding coughing, constipation, lifting heavy objects and other behaviors. Review the position of the placenta at 28 weeks of pregnancy. The central placenta previa in the sixth month of pregnancy causes repeated vaginal bleeding, the amount of vaginal bleeding is relatively small, you can go to the hospital to keep the baby in the hospital for treatment, you can follow the doctor’s orders of static magnesium sulfate to inhibit contractions and other fertility preservation treatments, and dynamically monitor the changes in the position of the placenta. If there is heavy bleeding during the period of fetal preservation, the pregnancy should be terminated in time to reduce the harm to the woman’s body. If the central placenta previa is detected in the 6th month of pregnancy, you should consult a doctor in time for the next step.
