Many women use abortion due to lack of knowledge of contraception, or lack of self-protection and unplanned pregnancy, and a small number of women have multiple abortions, taking abortion as “contraception”, while in practice we should promote the use of contraceptive methods to reduce the physical damage caused by abortion to terminate pregnancy. The following abortion complications: intraoperative: 1, abortion syndrome: due to the clamp pulling the cervix, dilating the cervical canal caused by the vagus nerve reflex, appear pale, cold sweat, heart rate drop, blood pressure drop. 2. Uterine perforation: High risk factors include hyperflexion of the uterus, multiple abortions, lactation, and uterine scarring. Perforation may result in hemorrhage, damage to the intestinal canal, etc., requiring surgical exploration and repair if necessary. 3.Leakage of aspiration: Mostly seen in small gestational sacs, uterine malformation (longitudinal uterus, double uterus), abnormal position of gestational sacs (partial uterine angle, uterine scar of cesarean delivery), uterus overflexion due to cesarean delivery, curvature, etc., which cannot be reached by suction tube. 4, haemorrhage: mostly seen in large gestational sacs, poor uterine contraction, abnormal coagulation, uterine perforation, uterine scar pregnancy, etc. Post-operative: 1. Residual: common cause is that the gestational sac is partial to the uterine horn and the uterus is too flexed for the suction tube to reach; the residual site is mostly found at the bottom of the uterus partial to the uterine horn. No surgeon can guarantee the absence of residuals because it is impossible to operate under direct visualization of the naked eye. 2, cavity adhesions: may have a serious impact on the re-pregnancy, some people have serious cavity adhesions and loss of fertility after an abortion, so whether to terminate the pregnancy should be careful. 3.Infection: It mostly leads to endometritis, tubal effusion, acute pelvic inflammatory disease, and sequelae of pelvic inflammatory disease (chronic pelvic inflammatory disease). 4. Infertility or ectopic pregnancy. Finally, we advise fertile women with childbearing requirements not to easily abort early pregnancies, especially those with multiple abortions, each of which may have lifelong regrets about the impact on future pregnancies. “Once I was pregnant, I miscarried then and never got pregnant again, if only I hadn’t miscarried then”, cherish each pregnancy and hope that such words and stories will never be repeated. The appearance of a fetus is a kind of fate with you, please give him/her a chance to survive.
