Progesterone 50mg two capsules per oral dose twice a day is the main treatment for preterm abortion. Other treatments for pre-eclampsia miscarriage include bed rest, prohibition of sexual intercourse, and if necessary, sedation with little risk to the fetus. Luteinizing insufficiency can be treated with intramuscular progesterone injection 10-20mg once a day or every other day and oral vitamin E for fetal preservation. For hypothyroidism, small doses of thyroxine tablets can be given orally. After two weeks of treatment, if vaginal bleeding stops and B-type ultrasonography indicates that the embryo is alive, the pregnancy can be continued. If clinical symptoms worsen, B-type ultrasonography reveals embryonic dysplasia, and HCG continues not to rise or fall, it indicates that miscarriage is inevitable and the pregnancy should be terminated. In addition, psychological treatment should be emphasized to make her emotionally stable and increase her confidence.
