[Kinetic modeling during continuous hemodiafiltration in patients with sepsis and multiorgan failure].

Kinetic simulation in terms of urea and creatinine is the best way of prescribing a dialysis dose and assessing its quality as it considers differences in a patient's body weight, the level of catabolism, the rate of equilibration, including the recirculation phenomenon noticeably observed under shock. A 2-pool model of distribution of urea and creatinine was employed in the study. The latter was carried out in 31 patients (17 males and 14 females) with sepsis and multi-organ failure receiving 50 sessions of continuous hemodiafiltration (CHDF).

[Systemic hemodynamics in constant hemofiltration in patients with septic shock].

Hemodiafiltration (HDF) is a method of pathogenetic therapy for the systemic inflammatory response syndrome in patients with sepsis and shock irrespective of renal failure. Systemic hemodynamics was examined in 18 patients with septic shock treated by HDF (2 groups). HDF was associated with stabilization of systemic hemodynamics in 50% patients (cardiac index, total peripheral resistance, index of the left heart work increased and the number of heart beats, central venous pressure, mean pressure in the pulmonary artery, pulmonary capillary wedging pressure decreased, oxygen consumption index increased, etc.

[Acute lung injury syndrome and hemodiafiltration].

Acute lung injury syndrome is one of the most frequent components of polyorgan failure, particularly resultant from sepsis. Replacing renal therapy can correct uremic disorders in the hemostasis and gaseous exchange disorders in the lungs by eliminating excessive fluid in case of hyperhydration and by eliminating inflammation mediators. The present study demonstrated a favorable impact of hemodiafiltration on ventilation oxygen status of patients with acute lung injuries, which was confirmed by positive changes in blood oxygen pressure, intrapulmonary shunt, alveolar-arterial oxygen difference, etc.

[High-volume hemodiafiltration in the treatment of sepsis and multiple organ failure: 2 methods of the elimination of TNF-alpha].

Permanent hemodiafiltration (PHDF) as a method for treating patients with sepsis and multiple organ failure (MOF) corrects the severity of generalized inflammatory reaction, which is caused by hyperproduction of bioactive substances. Cytokines can be eliminated from circulation by 2 methods of kidney-replacing therapy: convection and adsorption on hemofilter membrane. Despite the slight adsorption clearance, our results indicate that experimental data not always correspond to the clinical situation.
