先兆子痫有高血压、蛋白尿和水肿三项特征。妊娠时出现高血压通常与先兆子痫有关,先兆子痫如果发生惊厥即为子痫。血压稍升高也可惊厥,所以不能单纯根据血压来判定中度或重度先兆子痫。当出现下列一项即可诊断为重症先兆子痫:(1)观察相隔6小时,收缩压至少为160mmHg或舒张压110mmHg,(2)蛋白尿≥5g·24h~(-1),(3)尿少<40ml.24h~(-1),(4)大脑或视觉障碍,(5)肺水肿或紫绀。如果出现溶血、肝功能明显异常以及血小板减少,可诊断为HELLP综合症。HELLP是特殊类型的严重先兆子痫。子痫通常有先兆征状,如头痛、反射亢进和上腹部疼痛。
Pre-eclampsia has three characteristics of hypertension, proteinuria and edema. Hypertension during pregnancy is usually associated with preeclampsia, eclampsia if eclampsia is eclampsia. A slight increase in blood pressure can also convulsions, so you can not be based on blood pressure to determine moderate or severe preeclampsia. Patients with severe preeclampsia can be diagnosed by one of the following: (1) an observation of an interval of 6 hours with a systolic blood pressure of at least 160 mmHg or diastolic blood pressure of 110 mmHg, (2) proteinuria ≥5 g · 24h -1, (3) Urinary less <40ml.24h ~ (-1), (4) brain or visual impairment, (5) pulmonary edema or cyanosis. Hypopnea, abnormal liver function, and thrombocytopenia may be diagnosed as HELLP syndrome. HELLP is a special type of severe preeclampsia. Eclampsia usually has threatened symptoms such as headache, hyperreflexia, and pain in the upper abdomen.
