Gestational hypertension syndrome is a group of obstetric pregnancy complications centered on elevated blood pressure (SBP>=140mmHg and DBP>=90mmHg) with hypertension, edema, and proteinuria as the main symptoms. Moderate to severe hypertensive syndrome of pregnancy is a hypertensive sub-emergency and those with pre-eclampsia and eclampsia are hypertensive emergencies. Pre-eclampsia and eclampsia are severe gestational hypertension. Patients with preeclampsia present with headache, blurred vision, nausea, pain in the liver area and vomiting. Eclampsia is considered to have occurred when the patient has convulsions and coma on top of preeclampsia. The patient’s eyes are fixed, pupils are dilated, head is twisted to one side, teeth are tightly closed, followed by twitching of the corners of the mouth and facial muscles, tonicity of the limbs, clenching of both receipts, elongation of the arms, which develops rapidly into a strong convulsion, and the convulsion is accompanied by a pause of whistling and bruising of the face, and the convulsion decreases in amplitude after about one minute, and the muscles of the whole body are seen to be relaxing, and the pregnant woman recovers whistling with a deep and long snore, at this time there can be pulmonary edema, acute heart failure, acute renal failure, cerebrovascular accidents and other complications. At this time, there may be serious complications such as pulmonary edema, acute cardiac failure, acute renal insufficiency, cerebrovascular accident, aspiration pneumonia, placental abruption, fetal distress, intrauterine fetal death, etc. In the process of convulsions, various traumas are likely to occur, such as lip and tongue bites, falls, and even fractures. In the past, it was thought that pregnant women with mild pre-eclampsia should be hospitalized for bed rest to reduce the occurrence of severe pre-eclampsia, but now it is thought that they can be monitored in the outpatient obstetrics clinic. Mild pregnant women do not have to use antihypertensive drugs. For moderate to severe patients must go to the hospital for specialized treatment, first given magnesium sulfate, valium, etc. to stop convulsions, antispasmodic sedation, antihypertensive treatment with hydralazine, nifedipine commonly used, in addition to keep the airway open, oxygen; correct the water-electrolyte balance; timely termination of pregnancy; coagulation dysfunction, and other complications in the treatment of the need to strengthen the care of eclampsia, such as family members should reduce the patient’s psychological burden, etc., pay attention to Nutrition, ensure enough sleep and rest.
