The residue of medication abortion needs to be removed after 14 days because if the fetal sac is expelled smoothly after medication abortion, the ultrasound will be reviewed 2 weeks after the procedure and the residue in the uterine cavity will be found before considering the clearance procedure, most of the patients do not need clearance because medication abortion is an incomplete abortion and the real clearance needs to be observed for 2 menstrual cycles. Most medication abortions can expel the pregnancy product on the third day of the medication. If the vaginal bleeding is greater than 100ml while waiting for the expulsion of the pregnancy product, emergency evacuation is required. If the complete pregnancy product has been expelled and the vaginal bleeding is low, the patient can leave the hospital and go home for observation. It is recommended to go to the gynecological clinic for a follow-up ultrasound 14 days after the abortion. If the ultrasound reveals large residual tissues in the uterus, the uterus should be cleared. If the residue is small, oral progesterone or traditional Chinese medicine such as motherwort or biochemical soup can be taken to make the residue expel from the vagina with menstrual blood, and there is no need to perform the operation to clear the uterus. If the residue is large and accompanied by vaginal bleeding, surgery should be arranged as soon as possible to avoid heavy bleeding caused by poor contraction of the uterus or adhesion of the residue, which will increase the difficulty and risk of uterine removal. In addition, after the operation, you should rest in bed for 3 days, avoid spicy, oily and other stimulating foods, and change your underwear regularly to avoid infection.
