The main reason is that although the specific operation of painless abortion is the same as that of painful abortion, it is necessary to inject anesthesia before the operation, and the patient will complete the operation in a sleeping state, so there will be no pain during the whole operation, and the anesthesia will be metabolized in about 5 minutes after the operation, and the patient will be awake, so the use of painless abortion is relatively less harmful to the body. The damage to the body is relatively small. In addition, after the painless abortion, it is necessary to strengthen nutrition and pay attention to rest in order to make the body recover as soon as possible. 10 days after the abortion, you should go to the hospital for a corresponding examination to find out whether there are residual tissues in the uterus and whether the contraction of the uterus is normal.
