It is appropriate to review the abortion after 7-10 days because most of the blood in the uterine cavity has been drained and the bleeding has stopped by 7-10 days. A vaginal ultrasound or abdominal ultrasound can be performed to understand the recovery of the uterus and whether there is residue or blood in the uterine cavity. If there is residue or blood accumulation in the uterine cavity, timely removal of the uterus should be performed, because residual tissue can cause mechanization if it is prolonged, which can affect the woman’s menstruation and even have an impact on future fertility, and can make removal difficult. Therefore, you can choose to perform the cleaning operation under ultrasound monitoring. After the cleaning operation, you can give anti-inflammatory and hemostatic drugs orally, and keep the vulva clean and hygienic after the operation, and forbid intercourse and tub bath for 1 month.
