Abstract: Preeclampsia-eclampsia is a common obstetric critical disease and obstetricians have studied it assiduously for hundreds of years. We have attempted to explore the etiology, pathology, prevention, intervention, and treatment of preeclampsia-eclampsia, but we still have not arrived at a thorough understanding of its causes, and it is difficult to find effective prevention and treatment methods. Although the research process has been fraught with difficulties and frustrations, we are nonetheless gradually gaining a better understanding of the disease. Perhaps, in the near future, we will be able to acquire a full understanding of the disease and find better ways to ensure the health and safety of mothers and fetuses.
