With the introduction of the national “two-child” policy, many young mothers and fathers with one child have begun to “prepare” for their second child. The 2015 Chinese Medical Association guidelines for hypertension in pregnancy provide a basis for the management of hypertension in pregnancy. Let’s learn more about gestational hypertension. I. What is gestational hypertension? Hypertension in pregnancy is defined as a systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg measured at least twice in the same arm. if the blood pressure is lower than 140/90 mmHg, but 30/15 mmHg higher than the basal blood pressure, it is not considered as a diagnosis but requires close follow-up. For those who are found to have elevated blood pressure for the first time, the blood pressure should be retested at an interval of 4 h or more, and if the systolic blood pressure is ≥140 mmHg and/or diastolic blood pressure is ≥90 mmHg in both measurements, the diagnosis of hypertension is made. In severe hypertensive pregnant women with systolic blood pressure ≥ 160 mmHg and (or) diastolic blood pressure ≥ 110 mmHg, the diagnosis can be made after repeated measurements at intervals of several minutes. Why is it necessary to treat hypertension in pregnancy? The goal of treatment of hypertensive disorders of pregnancy is to prevent the occurrence of severe preeclampsia and eclampsia, to reduce maternal and infant perinatal morbidity and mortality, and to improve perinatal outcomes. Note: Eclampsia is a very dangerous disease. Eclampsia is a disease in which a pregnant woman suffers from dizziness and headache, sudden fainting and unawareness, eyes upward, twitching of hands and feet, generalized tonicity, waking up in a short time, recurrence after waking up, or even unconsciousness during late pregnancy or at the time of delivery or after a new birth, also called “pregnancy epilepsy”. Pregnancy eclampsia develops from the exacerbation of the signs and symptoms of pre-eclampsia. Eclampsia can occur during pregnancy, labor and delivery or within 24 hours after delivery, and is referred to as prenatal eclampsia, intrapartum eclampsia and postpartum eclampsia, respectively, and is one of the four leading causes of death in obstetrics. Once it occurs, maternal and child complications and mortality rates increase significantly, so special attention should be paid and emergency treatment should be given. So it is dangerous. If clinically symptomatic mothers-to-be should pay attention and go to the hospital for regular checkups. Pregnant women should be tested for urine protein or urinary routine at every prenatal checkup. Urine protein ≥ 0.3g/24 h or urine protein/creatinine ratio ≥ 0.3, or random urine protein ≥ (+) is defined as proteinuria. Proteinuria suggests that hypertension increases the burden on the kidneys and can increase the risk of pregnancy. How to deal with hypertension in pregnancy? 1. The main thing is to rest, sedation, prevention of convulsions, and personalized treatment of blood pressure. The main thing is to rest, sedation, prevention of convulsions, personalized treatment of blood pressure, indication of hypotension and diuresis, close monitoring of the mother and child, and termination of pregnancy at the right time. Treatment should be individualized according to the severity and classification of the condition. 2. Pay attention! Patients with hypertension in pregnancy must not take antihypertensive drugs on their own, but control blood pressure under the guidance of a regular professional physician. Commonly used antihypertensive drugs are adrenergic receptor blockers, calcium channel blockers and central adrenergic nerve blockers and other drugs. Commonly used oral antihypertensive drugs include labetalol (best evidence, highly recommended), nifedipine (best evidence, highly recommended) or nifedipine extended-release tablets (recommended), etc.
