Gestational hypertension is further divided into transient hypertension of pregnancy if preeclampsia is present at the time of delivery and the blood pressure is normal by 12 weeks postpartum, and chronic hypertension if the elevation in blood pressure persists beyond 12 weeks postpartum.,轻度：BP140/90mmHg，孕20周以后出现；尿蛋白300mg/24h或（+）。可伴有上腹不适、头痛、视力模糊等症状。Preeclampsia is hypertension associated with proteinuria and edema, occurring primarily in nulliparas after the 20th gestational week and most frequently near term. There are 2 categories of preeclampsia, mild and severe. mild preeclampsia is defined as the following: (1) HTN (BP140/90mmHg); (2) proteinuria exceeding 0.3 g in a 24-hour period or 1-2+ on dipstick testing;(3) Edema (hands or/and face) without other signs/symptoms,(2)子痫前期 preeclampsia,重度：BP160/110mmHg；尿蛋白2.0g/24h或（+）（+） ；血肌酐106mol/L；血小板100109 /L；微血管病性溶血（血LDH升高）；血清ALT或AST升高；持续性头痛或其它脑神经或视觉障碍；持续性上腹不适。Severe preeclampsia is defined as the following: (1) blood pressure greater than 160 mm Hg systolic or 110 mm Hg diastolic on 2 occasions 6 hours apart; (2) proteinuria exceeding 2 g in a 24-hour period or 2-4+ on dipstick testing; (3) increased serum creatinine ( 1.2 mg/dL unless known to be elevated previously); (4) oliguria 500 mL/24 h; (5) cerebral or visual disturbances; (6) epigastric pain; (7) elevated liver enzymes; (8) thrombocytopenia (platelet count 100,000/mm3); (9) retinal hemorrhages, exudates, or papilledema; and (10) pulmonary edema.,(2)子痫前期,子痫:子痫前期患者发生抽搐不能用其它原因解释子痫分产前子痫、产时子痫、产后子痫，以产前子痫多见。Eclampsia is the occurrence of seizures that cannot be attributed to other causes in a preeclamptic patient. prenatal eclampsia, intrapartum eclampsia, postpartum eclampsia clinical findings：seizure，Unconsciousness，apneic phase, hyperventilates after the tonic-clonic seizure ，Seizure-induced complications may include tongue biting, broken bones, head trauma, or aspiration. Pulmonary edema and retinal detachment.,(3)子痫 Eclampsia,子痫发作表现 抽搐发展迅速，前驱症状短暂，表现为抽搐、面部充血、口吐白沫、深昏迷；随之深部肌肉僵硬、继而发展为典型的全身高张阵挛惊厥、有节律的肌肉收缩和紧张，持续约11.5min，期间无呼吸；然后抽搐停止，呼吸恢复，但患者仍昏迷。最后意识恢复，但困惑、易激惹、烦躁。,(4)慢性高血压并发子痫前期 高血压孕妇妊娠20周前无尿蛋白，而妊娠20周后出现尿蛋白300mg/24h；高血压孕妇妊娠20周后突然出现尿蛋白增加或血压进一步升高或血小板100109 /L。Chronic hypertension is defined as hypertension that is present before conception or before 20 weeks gestation or persistence of hypertension after the puerperium (6 weeks).Chronic hypertension with superimposed preeclampsia:(1) no proteinuria before conception, but proteinuria exceeding 0.3 g in a 24-hour period after conception; (2)proteinuria increased or blood pressure greater or thrombocyte100109 /L,(5)妊娠合并慢性高血压妊娠前或妊娠20周前血压140/90mmHg，妊娠期无明显加重；或妊娠20周后首次诊断高血压，并持续至产后12周以后。defined as blood pressure equal to or greater than 140/90 mm Hg before conception or before 20 weeks gestation, and the hypertension is not increased significantly, or hypertension is firstly diagnosed after 20 weeks gestation and persists beyond 12 weeks postpartum.,并发症 脑出血、心力衰竭、肺水肿、急性肾功能衰竭、胎盘早剥、DIC、胎儿窘迫等。Complications: cerebral hemorrhage, Heart Failure, pulmonary edema, acute renal failure, placental abruption,disseminated intravascular coagulation, fetal distress,子痫惊厥后咬伤造成舌血肿,子痫患者头部CT箭头处可见低密度阴影,处理原则：妊娠期高血压的处理原则为休息、镇静、间断吸氧、密切监护母儿状态；子痫前期的处理原则为休息、镇静、解痉、降压、合理扩容和必要时利尿，密切监测母儿状态，适时终止妊娠；子痫的处理原则为控制抽搐，纠正缺氧和酸中毒，及时终止妊娠。 Rest, Sedation,Intermittent inhalation of oxygen, Close monitoring, spasmolysis, Control of hypertension, expand blood volume and diuretic therapy,termination of pregnancy,Control of seizures.,【处理原则 Treatment】,1有受伤的危险 与发生抽搐及意识丧失有关。2潜在并发症 胎盘早剥、肾衰竭。3焦虑 与担心自身及胎儿安危有关。High risk for injury，related to seizure or unconsciousness。Potential for complications, related to renal failure, placental abruptionAnxiety: related to worrying about the safety of herself and the fetus .,【护理诊断 nursing diagnosis】,【护理措施】,（一）妊娠期高血压患者的护理（二）子痫前期患者的护理（三）子痫患者的护理（四）产时及产后护理（五）心理护理（六）健康指导,（一）妊娠期高血压患者的护理,1休息与睡眠 可在家治疗，充足的睡眠（10小时/日）；以左侧卧位为宜。2间断吸氧 3饮食指导 蛋白质（100克/日）、蔬菜，补充维生素、铁和钙剂； 水肿不明显者不必严格限制食盐。 4密切监测母儿状况 监测患者体重、血压，询问患者有无头痛、视力改变、上腹不适等症状；协助患者进行尿蛋白测定、血液检查、胎儿发育状况和胎盘功能检查Be at home, get enough sleep:left lateral position.Intermittent inhalation of oxygen.Dietary Guidelines:Get close monitoring of the states of the mother and the baby,（二）子痫前期患者的护理,1一般护理 住院治疗，卧床休息，左侧卧位。床旁准备开口器、吸氧装置、吸引器、产包等抢救物资及硫酸镁、葡萄糖酸钙等药品。2密切监测母儿状况 3硫酸镁用药护理 硫酸镁是目前治疗妊娠期高血压疾病的首选解痉药物。General nursing: Be hospitalized,stay in bed:left lateral position.
