Most of the injections given for abortion are anti-inflammatory, including injections to contract the uterus, including injections to invigorate the blood flow and help the uterus to return to normal quickly. The anti-inflammatory injections can be given before the abortion to avoid infection due to the surgical operation. After the abortion, you can take levofloxacin plus ornidazole sodium chloride injection for intravenous drip as much as possible, and if there is more bleeding, you can add the uterotonin for intravenous drip, and the uterus can be restored to the normal shape in 5 consecutive days. In general, the injection of drugs as far as possible not more than 7 days, so as not to cause the vaginal flora environment imbalance, but more likely to cause fungal infections occur. After the miscarriage, the resistance is lowered, which makes it easier to be attacked by viruses. If possible, you should go for a follow-up ultrasound about 10 days after the miscarriage to make sure that the uterine cavity is normal and that there is no residual or accumulated blood.
