If the pregnancy is more than 70 days, that is, more than 10 weeks of pregnancy, within 14 weeks, you can choose drug abortion plus uterine clearance or artificial abortion scraping; more than 14 weeks, the fetus has basically formed, the bones are relatively hard, usually perform induction of labor. 1. 10-14 weeks of pregnancy: 1. Medical abortion plus curettage: usually the combined application of mifepristone and misoprostol interferes with the pregnancy, causing necrosis of the meconium, promoting uterine contraction and cervical softening and dilatation, and finally expelling the inactive blastocyst. However, because the fetus is larger at 10-14 weeks, the placenta has formed, resulting in a greater risk of intraoperative injury, bleeding and incomplete abortion, so on the basis of drug abortion often need to be supplemented by clearance; 2, abortion clamp scraping: clamp scraping is suitable for voluntary termination of pregnancy without contraindication or a disease (including genetic diseases) can not continue to pregnancy or other abortion failure. The method uses a combination of clamping and negative pressure suction, first using the oval clamp to clip out the embryonic tissue, and then using the suction to remove the fetus and embryonic tissue. Usually, in order to ensure that the forceps scraping is carried out smoothly, the cervix should be prepared for dilatation first, such as using seaweed sticks or prostaglandin drugs to dilate the cervix; for pregnant women with poor abortion pain tolerance, they can choose to use intravenous anesthetic drugs, which is usually called painless abortion. Second, more than 14 weeks of pregnancy: induction of labor is mostly suitable for those who need to terminate pregnancy as soon as possible for maternal or fetal reasons and have no contraindications to induction of labor. The procedure is mainly performed through abdominal amniotic puncture and the induction drug such as Levanox is injected into the amniotic fluid, usually 24 hours later, the pregnant woman can have regular contractions and the uterine opening is gradually opened under the stimulation of contractions and the pregnancy products can be discharged eventually.
