缺血性脑血管病时血管扩张剂的应用问题,目前尚有争议,有人认为尽管实验证明血管扩张剂有增加脑血液循环的作用,但尚难肯定其确切疗效。对此问题必须作具体分析。一、缺血性脑血管病的病理生理变化在缺血性脑血管病的不同阶段,按其病理生理变化的特征,可分为三种类型: (一)广泛缺血型:当脑血管闭塞后,首 It is controversial that the use of vasodilators in ischemic cerebrovascular disease is controversial. Some people think that although vasodilators have been shown to increase cerebral blood circulation, it is difficult to confirm the exact effect of vasodilators. This issue must be analyzed in detail. First, the pathophysiological changes of ischemic cerebrovascular disease in different stages of ischemic cerebrovascular disease, according to their pathophysiological characteristics can be divided into three types: (A) extensive ischemic type: when the cerebral vascular occlusion After the first
