A review is required after a painless abortion procedure. To do painless abortion surgery, the patient does not have special vaginal bleeding and abdominal pain after the operation, it is recommended that the patient 10 days after the review. This is because after the painless abortion, the patient’s bleeding can be cleaned up in 7-10 days, and the follow-up examination in 14 days or so can clearly observe whether there is any residue in the uterine cavity, and can also observe the patient’s uterine recovery. If there is a problem, it is easier to deal with it at this time, and if there is any residue, it can be treated with medication or another evacuation of the uterus. If the patient has abnormal bleeding or abdominal pain after the painless abortion, the patient should not be limited to a certain time for review, but should be reviewed at any time, because this situation should be considered there may be tissue residue, infection, or poor uterine regeneration possibilities.
