The medication for inducing labor is usually mifepristone with misoprostol, which is taken orally. Abdominal pain occurs 2-3 hours after taking the misoprostol, and vaginal bleeding accompanies the abdominal pain. However, each woman reacts differently, and some may experience abdominal pain even 1 hour after taking the medication. As the abdominal pain progressively worsens, the fetus as well as placental tissue will be expelled. If there is a lot of bleeding, it is necessary to give intramuscular injection of hysteronin in time to promote uterine contraction and discharge of residual tissue in the uterine cavity, and if necessary, to carry out a purging operation to remove the blood and residual tissue in the uterine cavity to facilitate uterine contraction. In the postoperative period, anti-inflammatory and uterine contraction drugs should be given routinely for treatment, and ultrasound should be conducted routinely in the hospital for 7-10 days after the operation to find out how the uterus is recovering.
