作者分析了65例脑动脉瘤破裂引发的急性蛛网膜下腔出血(SAH)的患者。42例在发病后6小时内入院,均行三维CT检查。患者的血压由静滴尼卡地平控制,必要时静注盐酸叔丁啡镇静。呼吸心跳骤停的患者行心肺复苏后进行检查。患者入院时按世界神经外科医师联合会(WFNS)的标准分级。 患者分成两组:A组13例,从上腔静脉至颈内动脉(ICA)的循环时间按Schad’s公式计算,循环时间(t)=n×60/f(s),n为相关系数,f为扫描前心率;B组为29例,循环时间由动态方法测量。CT扫描装置平行于眶耳线在ICA海绵窦段单层动态观察,扫
The authors analyzed 65 patients with acute subarachnoid hemorrhage (SAH) caused by ruptured cerebral aneurysms. 42 cases were admitted within 6 hours after onset, all underwent three-dimensional CT examination. Patient’s blood pressure is controlled by intravenous nicardipine, with intravenous infusion of buprenorphine if necessary. Patients with respiratory arrest stopped after cardiopulmonary resuscitation. Patients were admitted to the World Federation of Neurosurgeons (WFNS) criteria. The patients were divided into two groups: group A (13 cases), the cycle time from superior vena cava to internal carotid artery (ICA) was calculated by Schad’s formula, the cycle time (t) = n × 60 / f For the pre-scan heart rate; B group was 29 cases, the cycle time measured by a dynamic method.
