The low placenta position is always bleeding, the bleeding may be able to be preserved with little bleeding, and it is more difficult to preserve the bleeding with much bleeding. During pregnancy the placenta is in a low position, the low lying placenta is close to the cervical opening, as the uterus grows, the placenta peels away from its attachment and there is a small capillary rupture that can cause bleeding. Pregnancy is less than 34 weeks, the fetus survives in the uterus, the amount of vaginal bleeding is not large, you can expect treatment, usually take the lateral position to go to bed rest, during which sexual intercourse, vaginal examination, anal examination is prohibited, daily intermittent oxygen, stop bleeding with tranexamic acid, inhibit uterine contraction with magnesium sulfate, ritodrine hydrochloride, may be able to save the fetus. The low position of the placenta causes prolonged and heavy bleeding, which may cause shock, and termination of pregnancy is recommended regardless of whether the fetus is mature or not. Whether or not it can be saved depends on the number of weeks of pregnancy and the development of the fetus. For example, the fetus is not well developed in all aspects before 26 weeks of pregnancy, and it is very difficult for the fetus to survive repeated heavy bleeding. Pregnant women who bleed all the time due to the low position of the placenta should go to the hospital in time for treatment, otherwise prolonged vaginal bleeding will be harmful to both the pregnant woman and the fetus.
