Hypertensive disorders of pregnancy (HDCP) include hypertension in pregnancy, preeclampsia, eclampsia, chronic hypertension complicated by preeclampsia, and chronic hypertension in pregnancy, the first three of which are unique to pregnancy. The disease mostly occurs after 20 weeks of gestation and is characterized by hypertension and proteinuria, which may be accompanied by systemic multi-organ impairment or failure; at the same time, the fetus may have developmental delay due to placental hypofunction, leading to preterm delivery and immature babies, or in severe cases, fetal death in utero. How to prevent and early diagnosis is particularly important. It is important to pay attention to whether you have factors that predispose you to HDCP: first-time mothers, especially those over 35 years old, twin pregnancies, short and fat, malnourished, easily stressed, over-exercised, or working hard; family history of hypertension, mothers who had hypertension in pregnancy; your own previous pregnancy with hypertension; chronic hypertension, diabetes, nephritis, autoimmune disease, blood disorders, polycystic ovary syndrome, and fetal death before the current pregnancy. The disease is closely related to climate change. The occurrence of this disease is closely related to climate change and is likely to occur in winter and early winter when the cold season and barometric pressure are elevated. In order to prevent or better treat hypertension disease, the following should be noted: 1, during pregnancy to maintain a positive and optimistic attitude. 2, to enhance nutrition and proper rest during pregnancy: sleep in a left-sided position and ensure at least 8-10 hours of sleep per day; increase nutrition during pregnancy especially the intake of high protein, vitamins, folic acid, calcium, iron and other trace elements, reduce the intake of fat and salt, limit the intake of sweets and the intake of fruits should not be too much (2-3 taels of apples or other equivalent amount of fruits per day). Calcium supplementation of 2g per day since 20 weeks of pregnancy can reduce the occurrence of hyperemesis; vitamin E supplementation of 100-200mg per day is also beneficial to reduce the occurrence of HDCP. The most important thing is to have a regular prenatal checkup during pregnancy: if possible, it is better to monitor blood pressure before pregnancy to know the basal level of blood pressure, and those who are overweight (body mass index = weight kg/height m2 18-24 kg/m2 is considered as standard weight) should lose weight before pregnancy. Under normal circumstances, in the early and middle stages of pregnancy, you can have one check-up every month; after 28 weeks, every 2 weeks; after 36 weeks, every week; after the expected date of delivery, every 2-3 days. If you have high-risk factors or have been diagnosed with HDCP, you should follow your doctor’s instructions to increase the number of checkups. 4. Pay attention to the weight gain during pregnancy: take the weight during each maternity checkup, and if you have the condition or have been diagnosed with HDCP, you can monitor the weight after emptying the bladder in the morning at home and record it, and bring the data to the clinic; it is better to take the weight once a week, and if you have been diagnosed with hypertension, you can take the weight once every 3 days, and generally the weight gain should not exceed 0.5kg per week. If the weight gain is more than 0.5 kg per week, there is a possibility of edema. During late pregnancy, avoid standing for long periods of time and elevate the lower limbs during rest and sleep to promote venous return to the lower limbs, which can reduce the occurrence of edema. If the weight gain is too fast, or if there is dizziness, headache, blurred vision, chest tightness, breath-holding, upper abdominal discomfort, nausea and vomiting, lower abdominal pain, vaginal bleeding or fluid flow, reduced urine volume or coffee-colored or soy sauce-like urine, or elevated blood pressure, you should seek medical attention promptly. 5, each time the birth test blood pressure should be rested after arrival 10-15 minutes to calm down before measuring blood pressure: once the blood pressure is found to exceed 140/90mmHg during the birth test, consider the possibility of the existence of hypertension; or blood pressure exceeds 130/80mmHg, considered as critical hypertension, it is necessary to monitor blood pressure at home (preferably using a desktop mercury column sphygmomanometer, electronic sphygmomanometer measurement value is generally If possible, it is best to take the blood pressure at 2am and 8pm and record it in the morning. If you experience dizziness or blurred vision as described in section 4, you should seek immediate medical attention regardless of blood pressure level. If you do not have the above symptoms, but your blood pressure exceeds 150/100mmHg on self-test, you should also seek medical attention and increase or adjust your antihypertensive medication if necessary. 6, pay attention to the safety of the fetus in the womb: this is a task of the mother-to-be. The first will count fetal movement, generally 16-20 weeks of pregnancy can be detected fetal movement, the initial fetal movement about 3-5 times per hour, with the progress of pregnancy, the number of fetal movement gradually increased, reaching a peak in 28-32 weeks of pregnancy; to 38 weeks of pregnancy and then gradually reduced. The fetal movement also has a diurnal pattern, usually the fetal movement is even in the morning from 8 to 12, and then gradually decreases; in the afternoon from 2 to 3, the fetal movement is the least; and in the evening from 8 to 11, the fetal movement is frequent. Each pregnant woman will naturally feel a constant according to her own observation and use it as a standard to monitor the safety of the fetus in the womb. The most convenient time is to count the fetal movements 3 times in the morning, noon and night, each time for 1 hour, then add up the 3 times and multiply by 4 to get the number of fetal movements for 12 hours, generally the fetal movements are >30 times/12 h. Once you find that the fetal movements decrease, you should immediately consult a doctor. 7, at the same time alert to the occurrence of one of the complications of hypertension placental abruption: refers to the delivery of the fetus before the placenta is partially or completely stripped from the uterus, because at this time the fetal blood circulation is partially or completely interrupted, thus causing intrauterine distress or even death of the fetus, if not timely consultation, pregnant women will have hemorrhage, shock, blood non-coagulation and other complications, endangering the life of the mother-to-be. Therefore, during late pregnancy, you should sleep on the left side, avoid impact or trauma to the abdomen, avoid pressure on the abdomen (such as the past use of clothesline laundry room and other activities), once the abdominal pain or vaginal bleeding or abnormal fetal movement occurs, you must immediately seek medical attention. We hope that mothers-to-be will have regular maternity checkups, strengthen their self-monitoring, and actively cooperate with the physician’s guidance, so that they can successfully pass through the pregnancy and delivery process smoothly and safely and have a healthy and lovely baby.
