Официальное название
Investigation of Immunothrombosis in Intensive Care Patients With Septic Shock Undergoing Renal Replacement Therapy With the OXIRIS Membrane
Обзор
Sepsis remains a global scourge. Before the SARS-CoV-2 pandemic, the World Health Organization estimated approximately 49 million cases annually, resulting in 11 million deaths. Defined by dysregulated host response to infection, sepsis leads to vital organ failure. Renal dysfunction affects about half of ICU patients, necessitating extracorporeal renal replacement therapy in approximately 10% of cases, alongside coagulation system involvement typified by thrombocytopenia. Immunothrombotic phenomena are pivotal in sepsis pathophysiology, activating coagulation and disrupting immune responses. Microcirculatory impairment, mediated by neutrophils, monocytes, and platelets, worsens vital organ perfusion. Excessive production of Neutrophil Extracellular Traps (NETs) is implicated in microcirculatory compromise during sepsis.
Вмешательства
- Устройство Hemofiltration membranes (the oXiris membrane® and the HF1400® membrane)
The PRISMAFLEX® or PRISMAX® control unit (pre- and post-dilution with a prescribed treatment dose \> 25 ml/kg/h) with regional citrate anticoagulation and a substitution solution by PHOXILLUM will be used regardless of the type of membrane used (the oXiris membrane and the HF 1400 membrane), also as part of routine care provided in the ICU.
