Placental previa is the main cause of severe prenatal bleeding, and if not handled properly, major unexpected situations can occur. So for pregnant women with placenta previa, it is necessary to reduce outdoor activities appropriately in the middle and late stages of pregnancy, and if necessary, they can rest in bed more. So can placental previa, massive bleeding, and premature birth be preserved in terms of size? Let's all learn about it together!
If premature delivery is caused by placenta previa and massive bleeding, both sizes can be preserved in mid to late pregnancy. However, if bleeding occurs in early pregnancy, it can only protect adults. Therefore, pregnant women with placenta previa are very dangerous during pregnancy. Women need to develop good lifestyle habits during pregnancy preparation. If pregnant women have a habit of smoking, it can increase the risk of placenta previa. This is because smoking may lead to hypoxemia, making the placenta even larger and increasing the risk of placenta previa.
In addition, if the amount of bleeding from placenta previa is not significant, it generally does not have a significant impact on the fetus. But if the amount of bleeding is large, it can lead to maternal hemorrhagic shock, and the fetus may also experience oxygen pumping and die in the uterus. Placental previa in late pregnancy can affect the growth and development of the fetus. On the one hand, it may lead to reduced blood flow exchange, resulting in insufficient nutrition supply to the fetus. On the other hand, it may cause chronic hypoxia in the uterus.
