高血压急症的血压数值很难确定,它与个人差异及终末器官机能性不良的存在有关。如病人有高血压性脑病、严重恶性高血压并发急性左室衰竭、急性心肌梗塞或不稳定型心绞痛、壁间主动脉瘤、卒中或头部外伤,进行性肾功能不全、子痫伴惊厥或胎儿窘迫、术后出血或大面积烧伤等,则高血压急症应在1小对内降压。 Hypertensive emergency blood pressure value is difficult to determine, and it is related to personal differences and terminal organ dysfunction. If the patient has hypertensive encephalopathy, severe acute hypertension complicated by acute left ventricular failure, acute myocardial infarction or unstable angina, intracortical aortic aneurysm, stroke or head trauma, progressive renal insufficiency, eclampsia with convulsions or Fetal distress, postoperative bleeding or extensive burns, etc., then the emergency of hypertension should be a small pair of antihypertensive.
