There are currently 2 types of remedies for contraceptive failure, artificial termination of pregnancy methods are surgical abortion and medication abortion (commonly known as abortion and medication abortion). I. Induced abortion Surgical termination of pregnancy within 14 weeks of gestation for reasons such as unintended pregnancy, eugenics or disease, including negative pressure aspiration and curettage. 1. Negative pressure aspiration The principle of negative pressure suction is used to suck out the pregnancy from the uterine cavity, called negative pressure aspiration. Suitable for people: within 10 weeks of pregnancy. Contraindications: inflammation of the reproductive tract; acute stage of various diseases; physical condition that cannot tolerate the operation; body temperature above 37.5℃ twice (4 hours apart) before the operation. 2.Clamp scraping The cervix is loosened by mechanical or pharmacological methods, and then the fetus and placenta are removed with oval clamp. Suitable for people: 10~14 weeks because the fetus is larger and bones are formed at this time, it is easy to cause complications such as more bleeding, cervical laceration, uterine perforation, etc. Clamp scraping in large months should be avoided as much as possible. After abortion, in addition to good food and drink and good rest, you should pay attention to personal hygiene. Take a shower to clean the vulva in time, disinfect the toilet paper and change it from time to time; absolutely prohibit intercourse within one month to prevent bacterial infection. Second, medical abortion Suitable for: pregnancy ≦ 49 days; age < 40 years old healthy women; confirmed intrauterine pregnancy; not suitable for abortion (scarred uterus, lactation, cervical dysplasia, pelvic deformity). Medical abortion is less damaging to the body, more convenient, does not affect the life and study work on the same day, and its long-term complication rate is lower. However, compared with abortion, the success rate of medical abortion is lower, the vaginal bleeding is longer and cannot be controlled by medication. If the abortion is incomplete, the uterus must be scraped. This is a strong stimulus to the uterus, and with more scraping, the endometrium will suffer serious "visible damage" (the most dangerous being uterine perforation), which will make it easier for the placenta to be inserted and adhered when you get pregnant again, resulting in obstructed labor and retained placenta. The number of abortions the uterus can withstand depends on the time of termination, the number of abortions, the health condition and the technical ability of the surgeon. The more miscarriages you have, the more complications and sequelae you will have. Among women with secondary infertility, 88.2% have had an abortion, and women who have experienced repeated abortions are 2.5 times more likely to have a miscarriage during normal childbirth than those with no history of abortion, and the rate of premature birth is 5.44 times higher than those with one abortion. Data show that as many as 13 million abortions are performed in China each year. Repeat abortions are particularly serious in the abortion problem. Statistics from Guangzhou Women's and Children's Medical Center show that from January to July 2013, the rate of repeat abortions (two or more abortions) for patients at the hospital was 46.62%, and the rate of repeat abortions in just six months was nearly 2%. What is more worrying is that the abortion problem has shown a trend of low age. Data released by the National Population and Family Planning Commission's Institute of Science and Technology shows that women under the age of 25 account for more than half of the total number of abortions in China each year. College students have even become the "main force" of abortion. China's adolescent reproductive health survey report shows that about 60 percent of China's unmarried adolescents have a more tolerant attitude toward premarital sex, and 22.4 percent have had sexual intercourse. A survey in Guangdong Province shows that 48% of college students are in favor of "premarital sex between lovers". However, only 4.4% of unmarried teenagers have correct knowledge of reproductive health. More than half of the unmarried teenagers who had sex did not use any contraceptive method when they had sex for the first time. 21.3% of girls who have had sex have experienced pregnancy, and 4.9% have experienced multiple pregnancies. All the numbers are alarming. Every woman has only one uterus, which gives her the most mysterious power to "conceive life." Love yourself, love your uterus! Expert advice: Schools should promote empowering sex education. Through this mode of education, adolescents can fully grasp the knowledge of safe sex, develop a responsible attitude towards themselves and others, and eventually equip them with rational self-decision making skills on sexual issues. In conclusion, it is important to use scientific contraception and stay away from abortion. If you find an unwanted pregnancy, deal with it in time, and make sure to go to a regular hospital and get operated by an experienced doctor in order to minimize the damage to the uterus!
