Early unplanned pregnancy requires the choice of termination of pregnancy, which often makes it difficult for patients to make a decision, I make the following analysis for the reference of those who need it. Medication abortion: As the name suggests, it is a way to terminate pregnancy by using medication, such as oral mifepristone tablets and misoprostol tablets to expel the pregnancy capsule tissue by itself. The success rate is about 90%, and about 10% of patients need to be scraped. It is suitable for early pregnancies within 49 days of menopause with a gestational sac less than 2.5 cm, especially for postpartum lactation, within 1 year of cesarean delivery, and within 6 months of a history of abortion. The advantages are that there is no uterine manipulation and the risk of injury associated with uterine manipulation is reduced; the disadvantages are that it is not suitable for patients with impaired liver and kidney function, mifepristone and misoprostol allergy; significant gastrointestinal side effects (nausea/vomiting) occur with oral mifepristone. Induced abortion: It is a form of termination of pregnancy mainly through negative pressure suction to remove the pregnancy sac, with a success rate of about 99%. It is suitable for 70 days of menopause and the top rump diameter of the gestational sac is 2.8cm or less, while abortion of gestational sacs of 50-60 days of menopause is better. The advantages are high success rate and relatively short time needed for termination. The disadvantages are mechanical damage caused by uterine operation such as perforation and uterine adhesions.
