Аннотация
BACKGROUND: Sepsis-associated encephalopathy (SAE) is a diffuse dysfunction of the nervous system resulting from sepsis originating outside the central nervous system. Elderly individuals (≥65 years of age) constitute a particularly vulnerable population comprised by a high burden of underlying diseases and complications, which frequently leads to underdiagnosis or misdiagnosis. These patients are at increased risk of long-term or permanent central nervous system impairment, making rapid and accurate diagnosis and treatment especially critical. The review is expected to promote improvements in the diagnosis and treatment of SAE in elderly patients, ultimately achieving more standardized and efficient SAE management.
METHODS: We performed a literature search in four databases-PubMed, Embase, China National Knowledge Infrastructure (CNKI), and Wanfang-from inception to April 2025 using bilinguals (Chinese and English).
RESULTS: The diagnostic criteria for SAE in elderly individuals include the following: (1) sepsis; (2) new-onset neurological dysfunction; and (3) exclusion of other causes of neurological dysfunction. Physicians should develop tailored empiric anti-infective plans for elderly SAE patients, considering comorbidities, organ function, infection site, local bacterial spectrum, and resistance. The treatment protocol can be adjusted once the pathogen is identified. Stabilizing hemodynamics and ensuring cerebral perfusion are two fluid resuscitation strategies used in elderly SAE patients. An individualized approach to fluid resuscitation using restrictive fluid volumes should be employed. Supportive treatment for elderly SAE patients focuses on improving tissue perfusion/oxygenation, controlling blood glucose levels, and correcting internal imbalances. Early rehabilitation, nutritional support, cognitive training, and family-based emotional support are important components of comprehensive care.
CONCLUSION: The diagnosis and management of SAE in elderly patients support early recognition and timely intervention.
