They were sent to Beijing overnight for medical treatment. After the test results came out one after another, the initial judgment was once again confirmed: HELLP syndrome and severe pre-eclampsia were undoubtedly diagnosed, and the dangerous condition could endanger the life of mother and child at any time. The whole medical staff was immediately organized for relevant discussions, and after full communication with the patient and her family, surgery was immediately prepared to terminate the pregnancy. After intense and adequate preoperative preparations, the surgery began. The obstetrics, anesthesiology and neonatology departments worked closely together and quickly formed a strong rescue team. After more than an hour of efforts on the operating table, a healthy baby girl was finally delivered successfully after a series of dangerous situations such as maternal convulsions and neonatal resuscitation. Pre-eclampsia refers to the occurrence of hypertension, massive proteinuria and edema during pregnancy. If not controlled in time, it may develop into eclampsia, with life-threatening convulsions for both mother and child. And preeclampsia is the most serious kind of gestational hypertension, which is very common during pregnancy and is prone to heart failure, cerebral hemorrhage, kidney function, liver failure, postpartum hemorrhage, retinal detachment, blindness and other complications that endanger the health and life of pregnant women. With the development of the times and the liberalization of the second child, the characteristics of maternity have changed, such as increasing age of childbirth and overweight. These factors increase the risk of maternal hypertensive disorders in pregnancy, including preeclampsia. Disease mortality: perinatal mortality rate for those who delivered before 34 gestational weeks was 14.1%; for those who delivered before 28 and 30 gestational weeks, it was 33% and 20.5%, respectively; while for those who delivered before 24 and 28 gestational weeks, the perinatal mortality rate was 100% and 62%, respectively. In fact, pre-eclampsia is a common cause of maternal and perinatal morbidity and mortality in both developed and developing countries. Once it develops, there is no effective treatment unless the pregnancy is terminated. Therefore, early prediction and early intervention are key! Prediction-Prevention Screening for preeclampsia with PlGF (placental growth factor) and other markers in early pregnancy (11-13+6 weeks); Use of software to identify pregnant women at high risk of preeclampsia; Treatment of high-risk pregnant women with low-dose aspirin intervention. Monitoring and reassessment For pregnant women evaluated in early pregnancy, especially those at high risk for preeclampsia; monitoring and reassessment of preeclampsia using PlGF in mid-pregnancy (20-26+6 weeks); reassessment of the definition of high and low risk groups and adjustment of the perinatal monitoring protocol accordingly. Treatment principles: Basic principles: rest, sedation, indicated hypotension, diuresis, close monitoring, and termination of pregnancy at the appropriate time. Treatment is individualized according to the severity and classification of the disease. Hypertension in pregnancy: rest and monitoring; Pre-eclampsia: practice according to the above basic principles; Eclampsia: control convulsions and terminate pregnancy after stabilization; Chronic hypertension combined with pregnancy: focus on antihypertensive and pay attention to the occurrence of pre-eclampsia; Chronic hypertension combined with pre-eclampsia: both antihypertensive and pre-eclampsia treatment. Treatment measures: 1. General treatment Choose a suitable treatment site, and choose hospitalization or home according to the severity of the disease; ensure sufficient sleep, but absolute bed rest is not recommended; consume sufficient protein and heat, unlimited salt. 2., medication 3. lowering blood pressure: prevent serious complications such as eclampsia, cardiovascular accidents and placental abruption. Blood pressure lowering standard: 150-160 mmHg/90-100 mmHg. Target blood pressure: No concurrent organ function impairment: about 140/90 mmHg; concurrent organ impairment: about 130/80 mmHg.
