What should I check before abortion?

First, there is no inflammation or other contraindications after the relevant preoperative examination. Before the operation, patients need to undergo various examinations, usually including leucorrhea examination, B-ultrasound examination, gynecological examination, electrocardiogram, liver function examination and so on. If necessary, it takes more time to accept more inspection items, but basically it takes 1~2 hours. 1, determine the size of gestational sac, and after painless abortion, determine the size of embryonic tissue to avoid incomplete abortion. You can find out whether the reproductive tract is deformed, so you will make corresponding preparations before doing the operation to avoid some unnecessary injuries. 2, check whether ectopic pregnancy, if it is ectopic pregnancy, you can not do painless abortion surgery. Avoid empty suction. If it is too early, the gestational sac may not have reached the uterine cavity. Is there any abnormal position? After B-ultrasound, we can see its position clearly and avoid aspiration during operation. Second, the subjects' pregnancy days are about 35-50 days. If painless abortion is premature, because the embryo has just begun to develop and is still very small, it is easy to have empty aspiration or missed aspiration, leading to surgical failure or incomplete abortion. If so, it is necessary to clear the palace again. If the abortion is too late, because the days of pregnancy are too long, the gestational sac is already very large, and there will be more relative bleeding, which is very harmful to the body. Therefore, to do painless abortion, we must grasp the best opportunity and try to do it within 35-50 days of pregnancy.
