Painless abortions tend not to cause pain. Because painless abortion is usually performed after intravenous anesthesia, which has the advantages of fast onset and good anesthesia effect, patients usually do not feel pain during the procedure. However, after the procedure, the patient will have a slight pain, can feel the small abdominal cramps and lumbosacral pain, which is usually normal, no need to worry too much, it is recommended to go to the regular hospital for painless abortion surgery. Before having a painless abortion, the doctor must confirm the diagnosis of intrauterine pregnancy through HCG and ultrasound test results before the procedure can be performed. In addition, it should be noted that there is a time requirement for painless abortion, i.e. it is usually most appropriate to do it within 10 weeks of pregnancy. The reason is that the uterus is smaller within 10 weeks, so it is easy to suck out the pregnancy tissues and the reaction during the operation is lighter. Therefore, the earlier the procedure is performed, the easier and safer it is. After the painless abortion, you should pay attention to rest, prohibit sexual intercourse for one month, pay attention to keep the vulva clean and hygienic, diligently change underwear and underwear, and prohibit vaginal irrigation and sitz bath for those who have vaginal bleeding, so as not to cause episodic infection.
