Abortion is an invasive operation, and vaginal discharge examination is routinely performed before the operation. If inflammation of the reproductive system is found, the vaginal inflammation will be treated and the operation will be performed after the infection is controlled, which can avoid the possibility of bacterial upstream infection triggered during the operation and reduce the risk of endometrial inflammation, uterine adhesions, tubal adhesions and urinary tract infection. Broad-spectrum antibiotics are usually chosen for treatment. After 3 days of medication, the operation can be performed if the inflammation disappears. If the inflammation persists after 3 days of medication, it is usually added to 7 days for re-examination, when most of the infection can be cured. During the medication period, you need to pay attention to maintain a good lifestyle, avoid sex to prevent aggravating the infection; keep the vulva clean, use warm water to scrub, change underwear diligently, dry in the ventilation before re-use; diet pay attention to light, high protein and low fat, strengthen nutrition. If you are taking aspirin, heparin and other drugs that can cause bleeding, you should inform your doctor in advance and stop taking them as prescribed by your doctor. It should be noted that abortion is harmful to women and may lead to permanent damage, so it is recommended to take scientific contraceptive measures such as condoms during intercourse. For those who do not need to have children, ligation is feasible for both parties.
