The biggest difference between normal abortion and painless abortion is that painless abortion adopts general anesthesia technology. Intravenous general anesthesia is a fairly mature technology. After the patient enters the operating room, propofol is given intravenously to keep the patient under general anesthesia, and then the surgeon performs the abortion surgery on the patient. During the whole procedure, the patient is under anesthesia, with no pain and no recollection, and the patient will wake up naturally only after about 5-10 minutes after the procedure. Ordinary abortion, the patient did not receive any general anesthesia drugs during the operation, in the whole process of abortion surgery is completely aware of the operation, need to bear all the pain caused by the operation. Due to the fact that ordinary abortion will bring great pain to the patient’s surgical operation, nowadays the choice of people has been very few. In addition, ordinary abortion will increase the risks and complications associated with the procedure, such as perforation of the uterus and bleeding, as the patient may not be able to cooperate with the surgeon due to the pain during the procedure.
