Preeclampsia (PE) is a serious and common pregnancy complication, which refers to the clinical occurrence of edema, hypertension, proteinuria, headache, dizziness, vomiting, epigastric discomfort, and visual disturbance after 24 weeks of pregnancy. Or symptoms such as blood pressure and systolic blood pressure above 160 mm Hg (21.3 kPa). Some data show that about 3%-5% of pregnant women will develop pre-eclampsia. If treatment and intervention are not carried out in time, it may develop into pregnancy eclampsia, which is one of the four major causes of death in obstetrics, and will lead to maternal and fetal or neonatal death.
