Induced abortion refers to the use of artificial methods to terminate pregnancy due to unintended pregnancy, disease and other reasons, and is a remedy for contraceptive failure. Induced abortion has certain effects on women’s reproductive health, and the real purpose of family planning work is to do a good job of contraception and avoid or reduce unintended pregnancy. Surgical abortion is the use of surgical methods to terminate pregnancy, including negative pressure aspiration and curettage. Negative pressure aspiration is the use of the principle of negative pressure suction to extract the pregnancy from the uterine cavity. At present, the drugs used clinically are mifepristone and misoprostol, both of which are used in combination to terminate early pregnancy with a complete abortion rate of more than 90%. Misoprostol has uterine excitement and cervical softening effects, and mifepristone is a drug with anti-progestin and anti-glucocorticoid effects. Complications of abortion include intra- and post-operative bleeding, uterine perforation, abortion syndrome, missed or empty suction, incomplete suction, infection, amniotic fluid embolism, and long-term complications including cervical adhesions, uterine adhesions, chronic pelvic inflammatory disease, menstrual disorders, and secondary infertility. Abortion is both harmful to the body and the uterus, and good contraception is a task that we cannot ignore. Informed choice of contraceptive methods is an important element of quality family planning services, and women of childbearing age can choose appropriate safe and effective contraceptive methods according to their own characteristics and at different times.
