There is no way to perform a normal abortion in the third month of pregnancy. The reason is that ordinary abortion is usually performed with a suction tube, and in the third month of pregnancy, the fetus has already taken shape and formed bones, and there is already a placenta, so there is no way to perform suction with an ordinary suction tube. In the third month of pregnancy, abortion is mainly induced by the following methods: First, through medical abortion and uterus removal surgery, first take mifepristone and misoprostol to kill the embryo and promote uterine contractions to promote the expulsion of the dead embryo and the placenta, and then use the uterus removal surgery to remove the residual placenta tissue or membranes after the operation will be completed. However, if the patient’s cervical opening is relatively tight, in the use of medication abortion and uterine evacuation at the same time, also need to use a tube or a small water balloon dilatation of the cervix, so as to improve the chances of success of the operation. Second, you can use pincer scraping to induce labor, pincer scraping on the patient’s damage is relatively large, this method is mainly applicable to other methods of treatment after the failure of the backup choice.
