Painless abortion is relatively more effective. Painless abortion is more suitable for women who are more nervous or have a tighter cervical opening after cesarean section, the cervical opening relaxes better during painless abortion, and the surgical treatment can be completed faster, while painful abortion will prolong the surgical operation due to mental tension and pain. Whether you are doing painless abortion or painful abortion, you need to do ultrasound before the operation to diagnose the size of the gestational sac and its position in the uterine cavity, if the gestational sac is too small, it will easily lead to leakage of suction, and you need to pay attention to the careful operation during the operation to prevent complications, and after the operation you need to give proper rest, increase nutrition and anti-infection drug treatment.
