What are the most common cases of bleeding after abortion in early pregnancy?

In the early pregnancy, the amount of bleeding during vacuum aspiration surgery rarely exceeds 50 ml. If the amount of bleeding during surgery exceeds 200 ml, and the amount of bleeding during forceps curettage exceeds 400 ml, it is called artificial abortion bleeding. The reasons for more bleeding during surgery may be:

① When the gestational age is too long, the uterus is lactating, or there are multiple pregnancies, the uterus will be large, soft, and have poor contraction.

② When suctioning the uterus, the negative pressure is insufficient or the suction tube is too small, so the embryonic sac and decidua cannot be sucked out, the blood sinuses open, and bleeding occurs.

③ Coagulation dysfunction

④Uterine damage.

⑤ The placenta is located lower, and more bleeding may occur when the cervix dilates.
