脑水肿是由多种原因引起的综合症,其病因可归纳为:脑组织体积增大,如颅脑损伤,颅内炎症,脑缺血、中毒等;脑血流量增加,脑血管畸形,严重高血压;脑脊液量增加,如非通性脑积水;颅内占位,颅内肿瘤、血肿等;颅腔容积缩小、狭颅症、颅底凹陷等。 治疗脑水肿常用药物,20％甘露醇、速尿、50％葡萄糖、白蛋白,此药能提高血管内的胶体渗透压,使组 Brain edema is caused by a variety of causes of the syndrome, the etiology can be summarized as: brain tissue volume increases, such as brain injury, intracranial inflammation, cerebral ischemia, poisoning; increased cerebral blood flow, cerebrovascular malformations, severe Hypertension; increased cerebrospinal fluid, such as non-through hydrocephalus; intracranial space, intracranial tumors, hematoma, etc.; cranial cavity volume reduction, narrow skull disease, skull base depression. Treatment of brain edema commonly used drugs, 20% mannitol, furosemide, 50% glucose, albumin, the drug can increase intravascular colloid osmotic pressure, the group
