Abstract

Sepsis remains the leading cause of morbidity and mortality in intensive care units. The extracorporeal therapy in the complex treatment of sepsis seems to be the most promising direction. The aim of this study was to assess the safety and effectiveness of selective endotoxin adsorption on the basis of the analysis of our own experience with the intensive therapy for sepsis in adult cardiac surgical patients. Our single-center study included 143 patients with sepsis. One hundred and three adult patients received lipopolysaccharide adsorption procedures using Toraymyxin-PMX-20R columns. The historical control group included 30 adult patients received only conservative therapy, and 10 children (6.2–14 kg) received hemoperfusion with Toraymyxin-PMX-0.5R. After the lipopolysaccharide-adsorption course, we noted improving of the hemodynamic and respiratory parameters. A favorable effect of hemoperfusion was a decrease procalcitonin and endotoxin activity assay, expressed by changes of leukocytosis, a normalization of body temperature. The 28-day survival was 53% in the study group and 30% in the control group (P = 0.037). The 28-day survival of children who received selective hemoperfusion was 90%. Our own experience with the use of selective hemoperfusion in a fairly large group of cardiovascular patients with sepsis showed the safety and efficacy of these procedures.
