脑水肿是脑出血的直接后果,积极控制脑水肿、降低颅内压是脑出血急性期治疗的重要环节。甘露醇是临床最常用的组织脱水剂,通过其渗透性脱水作用,减轻脑组织的含水量,从而减轻脑水肿,降低颅内压。甘露醇还可以清除自由基,减轻迟发性脑损伤,保护神经功能。由于其降颅压作用强,起 Brain edema is a direct consequence of cerebral hemorrhage, and actively control brain edema, reduce intracranial pressure is an important part of the treatment of acute cerebral hemorrhage. Mannitol is the most commonly used clinical tissue dehydration agent, through its permeability dehydration, reduce water content of brain tissue, thereby reducing cerebral edema and reduce intracranial pressure. Mannitol can also remove free radicals, reduce delayed brain injury, protect neurological function. Because of its role in reducing intracranial pressure, starting
