When a pregnant woman is six months pregnant, the fetus has already taken on a human form and the best time to have an abortion has been missed at six months of pregnancy. If the fetus develops abnormally or is stillborn during this period, it can often only be delivered by induction of labor. There are five ways to induce labor: first, intra-amniotic injection of Levanox; second, induction of labor by placing a water bladder between the uterine wall and the fetal membranes; third, induction of labor by intravenous drip of indocin; fourth, induction of labor by misoprostol and other drugs; fifth, if all of the above methods fail, a cesarean section will be required in severe cases. Usually 6 months of pregnancy requires full dilatation of the cervix because the placenta has formed, the fetus is large and the bones have hardened. The difficulty of midterm induction of labor is almost similar to that of a normal full-term fetus. Therefore, induction of labor is like a normal birth, with the same pain, severe postpartum bleeding and perineal lacerations. After a successful induction of labor, the patient is usually kept in the hospital for 3 days for observation before being discharged. During the hospital stay, the doctor will choose the appropriate induction method according to the patient’s specific situation. As mentioned above, there are various methods to induce labor in the sixth month of pregnancy, and the specific method needs to be chosen according to the specific condition of the pregnant woman.
