Fetal arrest can occur at any stage of pregnancy, if suspected of embryonic arrest it is recommended to terminate the pregnancy under the guidance of a doctor, follow the doctor’s instructions to use mifepristone combined with misoprostol medication for treatment, and if necessary, at the judgment of the doctor to perform surgical abortion and induced abortion and other methods of treatment. If a pregnant woman has an abortion, it is recommended to go to a regular hospital for a relevant examination in a timely manner, under the judgment of the doctor to carry out targeted treatment, so as not to cause serious impact.
