Missed abortion is also called overdue abortion or stillbirth. If the embryo dies and stays in the uterus, the pregnancy products are usually discharged within 1 ~ 2 months after the symptoms appear. Therefore, it is called missed abortion if the embryo has not been naturally discharged 2 months after it stops developing.
Missed abortion is different from other general abortions, and it needs hospitalization, because it needs a doctor's clinical judgment, and then the uterus is cleared according to the situation. The stillbirth is attached to the uterine wall, which is very dangerous if it is not cleaned up. Pregnant women often have threatened abortion in the early pregnancy, and then the uterus no longer grows, but gradually shrinks, and it is not as soft as normal pregnancy. The pregnancy test changed from positive to negative, and the placenta clung to the uterine wall, making it difficult to separate. Or because of the lack of sex hormones, the uterine contractility is reduced, and it is not easy to discharge and the uterine cavity is missed. After the death of the embryo, the placenta dissolves, producing hemolytic enzyme into the maternal blood circulation, causing microvascular coagulation and consuming a lot of coagulation factors. The longer you stay in the uterine cavity, the greater the possibility of coagulation dysfunction and massive bleeding. You are hospitalized for observation and timely treatment. So missed abortion should be hospitalized.
