If it is determined that the fetus has stopped, surgery should be done immediately, and it is best to detect and treat it early. Avoiding the fetus to stay too long in the uterine cavity after death will easily cause inflammation and infection in the uterine cavity, which will seriously affect the health of the pregnant woman. If fetal abortion occurs in the first 3 months of pregnancy, abortion can be done. If the fetus is fully developed after 3 months of pregnancy, it is necessary to do the treatment of induction of labor at this time. The sooner the better, early detection and early treatment, so that the pregnant woman’s body will not cause serious damage, and will also recover faster during the recovery period. If the fetus stops developing and is not cleaned up in time in the uterine cavity, it will cause retrograde infection of the blood, which will easily lead to coagulation dysfunction in the pregnant woman and cause the possibility of sepsis.
