[Express diagnostics of endotoxaemia during postoperative period in cardiac surgical patients].

Medical technologies development and recent approaches in management of patients with septic complications during the early postoperative period present new obstacles to the laboratory service. Endotoxin is a main agent in the systemic inflammatory cascade and plays important role in sepsis pathogenesis. Recent express methods of diagnostics allow determining blood activity of endotoxin during 30-50 min. 55 ICU patients with clinical and laboratory signs of systemic inflammatory response syndrome (SIRS) after cardiac surgery were studied in the single-center prospective research. Endotoxaemia was diagnosed by express tests. Level of endotoxaemia was assessed before and after sorption in 15 patients receiving complex intensive care with selective lipopolysaccharide (LPS) adsorption. Endotoxaemia level assessment allows to define indications for different programs of intensive care in time and to assess its efficiency. Test systems for assessment endotoxin level based on the principle of interaction antigen - antibody (EAA and MACH-endotox spp.) is a most efficient for express diagnostics of endotoxaemia.
