2-3 days after abortion, the amount of vaginal bleeding is usually equal to the amount of menstruation or slightly more than the amount of menstruation, the bleeding becomes slightly more and can be observed first. If the bleeding is particularly heavy, it may be caused by incomplete abortion, poor uterine contraction, infection or accumulation of blood in the uterine cavity.1. Incomplete abortion: There is embryonic tissue residue in the uterine cavity after abortion, which may lead to continuous intrauterine bleeding. If the residual tissue is small, oral medication can be taken to promote the discharge of the residual tissue; if the residual tissue is more than 2.0 cm in diameter, the uterus is usually cleared. 2. Poor contraction of the uterus: It can easily lead to heavy bleeding or vaginal bleeding dripping. You can take medicine to shrink the uterus and oral antibiotics to prevent infection. If the bleeding is too much after the medication, you need to go to the hospital for examination in time to avoid serious consequences, oxytocin can be given intramuscularly or intravenously. If the bleeding is low, continue to take oral medication to strengthen contractions; give corrective anemia treatment if there is anemia; 3. Infection: if the bleeding increases with obvious abdominal pain, consider that it may be caused by uterine cavity infection, you need to go to the hospital to do gynecological ultrasound to observe the situation in the uterine cavity. If it is caused by infection, use antibiotics for anti-inflammatory treatment, such as amoxicillin, and at the same time take drugs to stop bleeding; 4. Accumulated blood in the uterus: after abortion, the uterus has not fully recovered, there will be a small amount of bleeding accumulation, if the bleeding cannot be discharged in time through the cervical canal, it will accumulate in the uterine cavity to form accumulation of blood in the uterus, which is mainly treated with drugs. If the amount of blood accumulation is not much, you can consider oral treatment with motherwort and regular review; if the amount of blood accumulation is much, you need to go to the hospital to undergo the operation to clear the uterus. After the abortion, you need to change the sanitary napkin in time and pay attention to the cleanliness of the vulva. Try to rest in bed and avoid high-intensity exercise. Stay away from cell phones, TV and other radioactive appliances, and recuperate quietly. Sexual intercourse is prohibited in order to prevent genital infection, which can cause more serious complications, and also to avoid another pregnancy in the near future.
