Most spontaneous abortions occur due to chromosomal abnormalities in the embryo, but can also be caused by maternal or external factors. Pre-eclampsia is the first stage of spontaneous miscarriage. If the fetus is found to be well developed, the pregnancy can be continued after treatment. When a pregnant woman is pregnant, especially in the early stage of pregnancy, she finds a small amount of vaginal bleeding, dark red or bloody discharge, without pregnancy discharge, followed by symptoms such as paroxysmal lower abdominal pain or low back pain, if the abdominal pain can be relieved after rest, she should be alerted to a preterm abortion; at this time, she should seek medical attention in time, if not treated in time, the abdominal pain and vaginal bleeding will increase, and the preterm abortion may develop into inevitable abortion, that is, miscarriage is inevitable. After the examination and diagnosis, the doctor will order the pregnant woman to rest in bed and prohibit sexual intercourse, and give her sedation, hemostasis and suppression of contractions if necessary. If the examination reveals that the luteal function of the pregnant woman is insufficient, progesterone injection or oral dydrogesterone tablets can be given. In addition to the above treatment, it is necessary to identify the cause of preterm abortion and then provide targeted treatment, such as corrective treatment of various maternal systemic and local diseases. If the fetus does not grow well during treatment, the pregnancy should be terminated. In summary, preeclampsia requires first lying down, prompt medical attention, and after examination and evaluation, either fetal preservation treatment or termination of pregnancy.
