The difference between painless abortion and medical abortion is the difference in abortion method, safety, effect and cost. Painless abortion is performed in a hospital within 10 weeks of pregnancy, where the embryo is removed from the uterus through intravenous general anesthesia and negative pressure suction. Medical abortion is a method of abortion in which the patient’s pregnancy is not more than 49 days old and the uterus is stimulated to contract by taking medication to induce the shedding of the uterine lining, thus achieving the purpose of abortion. Painless abortion has a high success rate, the patient does not feel pain during the abortion process, the doctor can operate conveniently, the broken embryonic tissue can be removed to the maximum extent, reduce post-operative cervical adhesions, bleeding and other complications, higher safety, better abortion results, the procedure can generally be completed in 0.5-1 hours. Patients can obviously feel abdominal pain, and the whole period of medication is 3 days. The possibility of incomplete abortion is higher, and the embryonic residue will also cause uterine bleeding and cervical adhesions, which will require the operation to clear the uterus, which is less safe and less effective, but the operation is simpler and easily accepted by the crowd. Painless abortion is relatively more expensive because it requires anesthesia and surgical operation, while medical abortion is a simpler and cheaper process. Whether it is a painless abortion or a medical abortion, patients need to take adequate rest after the abortion, avoid heavy physical labor, observe vaginal bleeding at all times, and seek medical attention in a timely manner if bleeding is severe and persistent.
