脓毒症相关性脑病(SAE)是脓毒症引起的弥漫性脑功能障碍,与延长患者住院时间和死亡率增加高度相关,可能导致永久性神经系统后遗症。SAE的病理生理机制较为复杂,可能包括神经炎症、血脑屏障功能障碍、脑微循环障碍、神经递质功能异常及氧化应激等。目前针对SAE的特异性诊断和治疗措施仍然缺乏,主要依赖基于临床表现的意识状态评估和早期预防、对症治疗。虽然近年来也出现了一些特异性治疗方法,但仍处于研究阶段,还远未能应用于临床。因此,进一步研究SAE的病理生理机制,探寻可靠的诊断和治疗措施十分重要。
Sepsis‑associated encephalopathy (SAE) is a sepsis‑induced diffuse brain dysfunction that is highly associated with prolonged hospital stay and increased mortality in patients
and may result in permanent neurological sequelae. The pathophysiology of SAE is complex and may include neuroinflammation
blood‑brain barrier dysfunction
cerebral microcirculatory disorders
neurotransmitter dysfunction
and oxidative stress. The specific diagnosis and treatment measures for SAE are still lacking
and mainly rely on the assessment of conscious state
early prevention
and symptomatic treatment. Though many specific treatments have emerged recently
they are still in the research phase and will not be used in a clinic immediately. Therefore
it is important to further research the pathophysiology of SAE and to explore reliable diagnostic and treatment measures.
