The hazards of visual ultrasound painless abortion can be divided into immediate and long-term hazards. The immediate hazards mainly include pelvic inflammation, even endometritis, adnexitis, pelvic inflammatory disease, and if the infection intensifies, it may even show symptoms of generalized poisoning and fever, as well as continuous vaginal bleeding and poor uterine contraction. Long-term risks include abnormal menstruation, constant vaginal bleeding, and even uterine adhesions, amenorrhea and infertility. The so-called visual ultrasound-guided painless abortion is based on the use of external anesthetic drugs to put the patient to sleep, reduce the occurrence of abortion syndrome, and reduce the physical and psychological damage to the patient during the abortion. The abortion can affect the patient’s life if not handled properly.
