Continuous veno-venous hemofiltration improves hemodynamics in septic shock with acute renal failure without modifying TNFalpha and IL6 plasma concentrations.
Continuous hemofiltration improves hemodynamics in critically ill patients by removing cytokines from the plasma. The mechanism, however, remains to be clarified since recent studies show conflicting findings. The present study was therefore designed to evaluate hemodynamic changes and kinetics of tumor necrosis factor (TNF)alpha, interleukin (IL)1beta and IL6 in patients with septic shock and acute renal failure (ARF) undergoing continuous veno-venous hemofiltration (CWHF), over a 24-hour period. ⋯ In patients with septic shock and ARF, CVVHF improves mean arterial pressure and systemic vascular resistance. This effect does not appear to be related to the removal of cytokines. The effect of CVVHF on mortality and morbidity in the long term, in septic shock has still to be established.
