Severe sepsis and septic shock are conditions associated with high morbidity and mortality. The disproportionate release of pro-inflammatory and anti-inflammatory mediators caused by the septic insult is the promoter of multiple organ dysfunction. Conventional hemodialysis, hemofiltration or a combination of both can be a good option to replace the deteriorating renal function in critically ill patients by the removal of nitrogen compounds (small molecules). However, this "renal dose" is insufficient for the removal of inflammatory mediators (medium molecules), and therefore contributes little to the cardiovascular stabilization of patients with septic shock. In this setting, a higher dose of ultrafiltration (> 50ml/kg/h) or "septic dose" may be needed. In this review article, we have analyzed the clinical and pathophysiological rationale for the use of high volume hemofiltration in patients with septic shock.
