In the pregnancy examination, obstetric ultrasound is a must-do item for obstetric examination, which will prompt the fetus, placenta, amniotic fluid and other conditions. Some pregnant mothers' report sheets sometimes show the "placenta low" state, for such a prompt, some doctors say that it is okay, do not have a big move on the line; and some doctors say that they can not give birth smoothly, but also be careful that there will be "heavy bleeding", so what is the "placenta low" what is going on? Now the obstetricians will explain it to you.
01. Normal placental position
Normally, the position of the placenta should be 7 cm above the cervical opening, or 3-7 cm, such a position will not affect childbirth and activity.
02. Low placenta position
The medical criterion for placental hypothesis is that the distance between the placenta and the inner cervical opening is less than 2 cm. The placenta is located so close to the inner opening of the cervix can cause the placenta and uterus to be unstable and misaligned as the woman moves. Activities such as squats, striding, and climbing stairs can easily cause bleeding.
03. Placenta previa position
In order to obtain a better blood supply, the position of the placenta gradually moves upwards as the gestational age increases, so most low placentas are already far away from the inside of the cervix after 28 weeks. Only a very small number of placentas still attach to the inner opening of the cervix, or even cover the inner opening of the cervix, a situation called placenta previa. It is a common cause of vaginal bleeding in the third trimester and one of the serious complications of pregnancy.
Pregnant women with low placenta and placenta previa, if repeated bleeding during pregnancy is easy to cause miscarriage, premature birth, infection, if the placenta is implanted in the uterus, the risk of postpartum bleeding is significantly higher than that of normal pregnant women, and the risk of postpartum anemia and puerperal infection is also significantly increased.
Pregnant women with multiple pregnancies, advanced maternal age, multiple miscarriages, and a history of uterine cavity manipulation are significantly more likely to have low placenta and placenta previa than normal pregnant women. Once ultrasound B has diagnosed placenta low or placenta previa, it is important to prevent bleeding during pregnancy. The key to preventing bleeding during pregnancy lies in the strict self-management of daily life.
Try to avoid the following actions:
1. Strenuous activities: such as jumping, climbing stairs, etc.;
2. Stand for a long time;
3. Squat;
4. Increase abdominal pressure activities, such as lifting/lifting heavy objects, exerting force to defecate, etc.;
5. Activities that are easy to induce contractions: such as diarrhea, sexual life, etc.
Obstetricians remind that although pregnant mothers should be extra careful during pregnancy, it does not mean that they must stay in bed throughout pregnancy, and it is okay to walk around daily and take short walks. Pregnant mothers should pay more attention to the fact that they must have regular obstetric examinations to monitor the position of the placenta and fetal development, and look forward to the arrival of the little angel in the professional company of the doctor.
