How does placenta previa do

summary

Placenta previa is very easy to cause massive hemorrhage in pregnant women. Therefore, once placenta previa occurs, pregnant women should pay enough attention to it. Otherwise, it may lead to their own physical problems or problems in the fetus due to placenta previa. Once placenta previa occurs, not only doctors need to help treat it, Also need to through self-control and other aspects, effectively alleviate their own physical symptoms, to avoid their own placenta previa problems.

How does placenta previa do

Method 1: absolute bed rest, correct anemia and use antibiotics to prevent infection. If the gestational age is less than 34 weeks, inhibit uterine contraction and give fetal lung maturation. At the same time, closely observe the condition and carry out relevant auxiliary examination. If repeated massive bleeding, pregnancy should be terminated as appropriate.

Method 2: after the discovery of placenta previa, the treatment can also be used to terminate pregnancy. At present, the more commonly used methods are cesarean section and vaginal delivery. Cesarean section is the main way to terminate pregnancy with placenta previa. Before operation, we should actively correct shock, infuse and transfuse blood to supplement blood volume, pay attention to the position of uterine incision during operation, and try to avoid the placenta as much as possible. The delivery of the fetus through a hole in the placenta will often cause massive hemorrhage, unless we have to.

Method 3: vaginal delivery, vaginal delivery is the use of fetal presentation to compress the placenta to achieve the purpose of hemostasis, this method is only applicable to marginal placenta previa and the fetus is the head position. In labor after bleeding, but not much blood, maternal general condition is good, labor progress smoothly, it is estimated that in a short period of time can end the delivery. However, it should be noted that the marginal placenta previa with placenta attached to the posterior wall of uterus is prone to placental blood pressure and fetal hypoxia due to the compression of placental receptive head and sacral bone organs in the process of fetal head descending. Therefore, close monitoring is needed in the process of labor.

matters needing attention
