为研究颅内压降低对脑梗塞患者脑血流的影响，随机选择60例患者，20％甘露醇250ml，半小时内静脉滴入，治疗前后做TCD检查；结果发现治疗后大脑前、中、后动脉及椎基底动脉平均血流速度（Vm）增加，与治疗前比较，P＜0．01，治疗后47例患者Vm增加，占78．3％，其中21例患者1条动脉Vm增加，15例2条动脉Vm增加，11例3条以上动脉Vm增加，而仅13例Vm降低，占21．7％，与Vm增加者相比较明显少。故认为颅内压降低可使大脑平均血流速度增加，有利于脑梗塞患者脑血流改善。
In order to study the impact of decreased intracranial pressure on cerebral blood flow in patients with cerebral infarction, 60 patients were randomly selected, 20% mannitol 250ml, intravenous infusion within half an hour before and after treatment to do TCD examination; results showed that after treatment, The average velocity of Vm increased in the posterior arteries and vertebrobasilar arteries compared with those before treatment (P <0.01). Vm increased in 47 patients (78.3%) after treatment, of which 21 patients had an increase in Vm, Vm increased in 15 cases of 2 arteries, Vm increased in 11 cases of more than 3 arteries, while only 13 cases of Vm decreased, accounting for 21.7%, compared with Vm increased significantly less. Therefore, that the reduction of intracranial pressure can increase the average cerebral blood flow rate is conducive to improving cerebral blood flow in patients with cerebral infarction.
