大面积脑梗死通常与脑水肿相伴而存在。脑水肿引起的脑组织移位通常也是大面积梗死死亡的主要原因。对脑水肿并发中线结构移位的治疗主要为渗透性药物如甘露醇的应用 ,这种治疗通过建立透过血脑屏障的渗透压梯度 ,减少脑组织水含量而减轻脑水肿。有些实验报道高渗透液能减少脑 Large areas of cerebral infarction are often associated with cerebral edema. Cerebral edema-induced brain tissue displacement is also often the leading cause of large-area infarction death. The treatment of brain edema complicated by midline structure displacement is mainly the application of osmotic drugs such as mannitol. This treatment relieves cerebral edema by establishing an osmotic pressure gradient across the blood-brain barrier and reducing the water content of brain tissue. Some experiments reported that high permeate can reduce the brain
