An abortion should be performed immediately after the discovery of fetal abruption and is most suitable for painless abortion if the embryo is not more than 70 days gestational age at the time of abruption. An abortion should be performed immediately after the discovery of embryonic arrest to remove the embryonic tissue from the uterine cavity. This is to prevent the dead embryonic tissue from releasing anticoagulant substances in the uterus, which can lead to clotting abnormalities in pregnant women. Dead embryos that have been in the uterine cavity for a long time also tend to mechanize, making them more difficult to remove. If the embryo has developed for less than 70 days, a painless abortion can be performed. After the occurrence of fetal arrest, it is necessary to go to the hospital for examination in a timely manner, according to the results of the examination, under the guidance of the doctor. After the abortion, you should strengthen the nutrition, pay attention to rest, prohibit sexual life for 2 weeks, and also pay attention to personal hygiene, change underwear and wash underwear, keep the vulva dry and clean.
