To prevent cervical adhesion after abortion, it is mainly recommended to do the following: 1, take oral antibiotics for about 3 days after the operation to prevent pathogenic bacterial infections. 2, do not have sex after the operation, so as not to cause infections. 3, pay attention to do not sit in the bath within 1 month after the operation, to keep the vulva locally clean, which will also reduce the symptoms of infections and reduce the chances of adhesion. 4, the localization of cervical adhesion is related to inflammation, which is also related to the local damage to the cervical mucosa caused by the operation process. There is a relationship with the surgical process that leads to localized damage to the cervical mucosa, it is recommended that anti-inflammatory treatment be given after the abortion. If you have lower abdominal pain about 1 month after the abortion, you should suspect that it is due to the cervical adhesion that causes the lower abdominal pain when menstruation, the menstrual blood is not able to be discharged, and it is recommended to go to the hospital as soon as possible to do a checkup. If there is fluid in the uterine cavity as detected by ultrasound, cervical dilatation should be performed to allow the menstrual blood to drain smoothly, and anti-infective treatment should be given after the operation to prevent the adhesion from recurring.
