Painless abortion uses a new, safe and effective intravenous general anesthetic. The patient is given the drug intravenously and can go to sleep in about 30 seconds. After about 3 minutes, the doctor can complete the procedure without the pregnant woman being conscious, and the whole procedure takes only 5-7 minutes. After the procedure, the pregnant woman can fully recover her consciousness and leave the hospital in 30 minutes on her own. Painless abortion is an abortion performed under intravenous anesthesia, which is based on suction abortion with intravenous general anesthesia and no pain during the procedure. A short-acting intravenous anesthetic is used to allow rapid distribution throughout the body after sedation, putting the patient to sleep within 40 seconds. Within 5 to 10 minutes of the drug’s effect, the procedure is successfully completed under ultra-guided visualization. Since the doctor performs the operation under visualization, this objectively ensures a short operation time and a thorough operation, thus avoiding complications such as uterine perforation, incomplete suction, missed suction and abortion syndrome caused by tension, fear, agitation and struggle during the abortion, and allowing the patient to complete the operation easily in a sleep state. The patient can go home immediately after the operation without hospitalization. It is especially suitable for those who are afraid of pain after first pregnancy, cesarean delivery, multiple abortions, mental factors that make it difficult to cooperate with the operation, and those who cannot tolerate painful stimulation due to hypertensive heart disease.
