脓毒性休克血流氧流分型与临床管理专家共识(2025)OA

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infec-tion.Septic shock is the primary cause of mortality in sepsis,with its core pathophysiological mechanism being severe ischemia and hypoxia in critical units—composed of microcirculation and the mitochondria of functional cells—resulting from disruptions in blood flow and oxygen flow following a dysregulated host response.Due to the systemically convergent yet clinically heterogeneous nature of the host response,current understanding and management strategies for hemodynamics remain inconsistent,often leading to inadequate resuscitation or over-treatment.To improve the quality of care,based on a systematic review of the"blood flow-oxygen flow"theory,an expert panel emphasizes reevaluating septic shock from an integrated perspective of blood flow and oxygen flow,and has formulated the Expert Consensus on Blood Flow and Oxygen Delivery Phenotyping and Clinical Management of Septic Shock(2025).The consensus proposes that clinical typing of blood flow-oxygen flow should comprehensively consider cardiac function,vascular tone,oxygen flow utilization status in critical units,and disease trajectory,while optimizing subtype identification by integrating host response phenotypes and artifi-cial intelligence technologies.It advocates establishing a continuous assessment system through multi-site oxygen flow monitoring for organ perfusion,peripheral perfusion monitoring,and critical care ultrasound.Under the framework of the"critical care triangle",the consensus promotes the implementation of individualized,bundled management strategies,providing guidance for multiple management points to restore blood flow-oxygen flow matching,reduce the risk of organ failure,and decrease patient mortality.
