脓毒症脑病又称脓毒症相关性脑病(sepsis-associated encephalopathy,SAE)是由全身炎症反应引起的弥散性脑功能障碍,其发病率在8%～70%合并SAE时脓毒症的死亡率明显增加。Young等随访ICU内69例脓毒症患者,49例合并不同程度的脓毒症脑病,其中轻微型脑病(mild encephalopathy)17例,病死率为35%;严重型脑病(severe eneephalopathy)32例,病死率为53%。可见SAE的严重程度与患者的死亡率呈正相关。而幸存者常有长期记忆功能 Sepsis-associated encephalopathy (SEE), also known as sepsis-associated encephalopathy (SAE), is a diffuse brain dysfunction caused by a systemic inflammatory response, the incidence of which is associated with the death of sepsis at 8% to 70% with SAE The rate has increased significantly. Young and other follow-up ICU 69 sepsis patients, 49 patients with varying degrees of sepsis encephalopathy, including mild encephalopathy in 17 cases, the mortality rate was 35%; severe encephalopathy (severe eneephalopathy) in 32 cases, Case fatality rate was 53%. Shows the severity of SAE and the patient’s mortality was positively correlated. Survivors often have long-term memory
