While hypertension is commonly thought of as a common chronic disease of the middle-aged and elderly, it is not known that pregnant women are also prone to abnormally high blood pressure. This is known as hypertensive disorders of pregnancy – a group of disorders in which pregnancy and hypertension coexist and is one of the major problems affecting the health of mother and child. Eclampsia is the most serious stage of hypertensive disorders in pregnancy and is the leading cause of maternal and child mortality. The condition of hypertension in pregnancy is complex and rapidly changing, and it is important to monitor the condition before, during and after delivery in order to understand the severity and progression of the condition and to intervene in a timely and reasonable manner to avoid adverse outcomes. Depending on the condition, the doctor may need to conduct the following examinations: 1. Basic examination Find out whether there are symptoms such as headache, chest tightness, blurred eyes and epigastric pain, check blood pressure, blood and urine routine, calculate body mass index, monitor urine volume, fetal movement and fetal heartbeat. 2.Special examination for pregnant women: fundus examination, coagulation index, heart, liver and kidney function, blood lipids and electrolytes, etc. 3.Special examination for fetus including fetal development, ultrasound and fetal heart monitoring, monitoring fetal condition and umbilical artery blood flow. The main purpose of treating hypertensive disorders during pregnancy is to control the disease, prolong the gestational weeks and ensure the safety of mother and child. The basic treatment principles are rest, sedation and antispasmodic; for those with indications, antihypertensive and diuretic treatment can be performed, and the condition of mother and child can be closely monitored and pregnancy can be terminated when appropriate. The treatment should be individualized according to the severity of the disease. Pregnant women should pay attention to rest, ensure sufficient sleep, and take the left side position. Ensure sufficient protein and calories. Give antihypertensive treatment if necessary, with the aim of preventing serious complications such as eclampsia, cardiovascular accidents and placental abruption. In terms of prevention, unfortunately there are no effective methods for the general population to prevent hypertensive disorders of pregnancy. For high-risk groups, the following measures have some effect: 1, proper exercise You should exercise moderately during pregnancy and arrange rest reasonably to keep your body healthy during pregnancy. 2.Rational diet Severe restriction of salt intake during pregnancy is not recommended, nor is restriction of calorie intake for obese pregnant women. 3.Calcium supplementation The daily intake of calcium is at least 1 gram. 4.Aspirin anticoagulation therapy Pregnant women with a history of preeclampsia, recurrent seizures or seizures before 34 weeks of gestation should take low dose aspirin daily starting at the end of early pregnancy. 5. Bed rest or activity restriction is not currently recommended to prevent or treat preeclampsia, and vitamin C and vitamin E are not recommended to prevent preeclampsia.
