[Immunomodulatory effect of extracorporeal hemocorrection in patients with surgical sepsis].

The study was undertaken to evaluate the immunomodulatory effects of various methods of extracorporeal hemocorrection in septic patients. Thirty-two patients in whom the course of the underlying disease was complicated by the development of sepsis were examined. A package of therapeutic measures involved debridement of an infection focus, de-escalation antibacterial therapy, nutritional support, and immunomodulatory therapy. All the patients underwent procedures of plasma filtration and continuous venovenous hemofiltration; granulocytopheresis was carried out in 5 patients. Granulocytopheresis was shown to eliminate dead leukocytes from the bloodstream within a few hours, which contributed to clinical improvement. Plasmafiltration in patients with sepsis resulted to a reduction in the degree of a systemic inflammatory reaction, to normalization of coagulation homeostasis, which indirectly affected immunological parameters. Continuous venovenous hemofiltration made it possible to make continuous elimination of the low and average molecular-weight substances, corrected liquid balance, and well affected gas exchange in the lung.
