脑水肿(Brain Edema)是脑卒中和其他许多中枢神经系统疾病常见的病理生理现象。脑水肿发生时,脑细胞缺血缺氧,ATP产生不足,能量代谢障碍,致使细胞膜泵功能障碍,细胞内Na+、Ca2+大量潴留,引发Ca2+超载,线粒体肿胀,细胞死亡,从而诱发代谢异常。及时监测脑水肿可作为观察颅脑疾病患者病情进展、判断手术时机、指导治疗方案 Brain Edema is a common pathophysiological phenomenon of stroke and many other central nervous system diseases. Cerebral edema, cerebral ischemia and hypoxia, lack of ATP production, energy metabolism disorders, resulting in membrane pump dysfunction, a large number of intracellular Na +, Ca2 retention, trigger Ca2 overload, mitochondria swelling, cell death, and thus induce metabolic abnormalities. Timely monitoring of brain edema can be used as observation of brain disease progression, determine the timing of surgery, guide the treatment program
