If the abortion is incomplete, i.e., there is an incomplete abortion, once the diagnosis is confirmed, the residual tissue in the uterine cavity should be removed as soon as possible by purging or forceps surgery. The removal of the uterus may cause bleeding, perforation of the uterus, infection and other complications, if the operation is not appropriate, repeated scraping may cause endometritis or uterine adhesions. The removal of uterus, i.e. scraping, bleeding, uterine perforation and infection are the main complications of scraping. Preoperative preparations such as infusion and blood preparation should be made, and strict aseptic operation must be carried out during the operation. Operators worry about incomplete removal during operation, repeated scraping, which not only injures the basal layer of the endometrium, and even scrapes out the myofibrous tissue, resulting in endometritis or uterine adhesions, which can lead to amenorrhea. Bleeding time is long, bleeding is the main side effect of drug abortion, a very small number of people can bleed a lot and need emergency scraping to terminate pregnancy. Therefore, both medication abortion and purging must be carried out in regular medical institutions to avoid accidents. If there is a slight bleeding after the removal of the uterus, which is not relieved by proper rest and shows a trend of continuous aggravation and is accompanied by abdominal pain, you should consult a doctor as soon as possible, and after a clear diagnosis of the causes, you will be guided by a doctor for symptomatic treatment and conditioning.
