After an embryonic arrest occurs, it is necessary to terminate the pregnancy promptly, and a painless abortion surgery can be chosen. During the abortion surgery, anesthetic drugs are administered, usually intravenous anesthesia. During the procedure, the patient is in a sleeping state, completely unconscious, and therefore does not feel any pain. Generally, a few minutes after the surgery, the effect of the anesthetic wears off quickly and the patient will wake up. Therefore, patients can rest assured, especially for women who are particularly sensitive to pain, using painless abortion can reduce their fear and alleviate some of the pain during the procedure.
