The hazards of hemostasis by curettage are multifaceted, including near-term hazards such as organ damage and long-term hazards such as infection. 1. Immediate hazards: (1) Organ damage: such as improper operation will cause perforation of the uterus and uterine peripheral organ damage such as bladder, rectum perforation. (2) Bleeding: there will be bleeding during the scraping process. 2. Long-term hazards: (1) Infection: endometritis, salpingitis and pelvic inflammatory disease may be caused by scraping, so it will cause tubal obstruction resulting in infertility. (2) Endometrial adhesion: as scraping will seriously damage the endometrium, when it causes damage to the basement membrane, it will be irreversible and will cause thinning of the endometrium, uterine adhesion, amenorrhea and infertility. When women need to scrape the uterus to stop bleeding, it needs to be completed by a professional doctor, and if there is any discomfort after the operation, they need to consult a doctor in time.
