Necrotizing fasciitis represents a life-threatening infectious condition that causes spreading necrotisis of superficial fascia and subcutaneous cellular tissues. We describe the case of a patient diagnosed with septic and toxic shocks leading to multiple organ failure successfully treated with a combination of extracorporeal life support, continuous renal replacement therapy, and a hemoadsorption device. ⋯ This case describes the successful use of CytoSorb® with continuous renal replacement therapy and extracorporeal life support in a combined way to overcome a critical phase of septic shock in a young adult patient. This combination of treatments turned out to be efficient for this patient in the context of necrotizing fasciitis.

Observational Study
Clinical impact of regional citrate anticoagulation in continuous renal replacement therapy in critically ill patients.
Regional citrate anticoagulation (RCA) is being used increasingly in continuous renal replacement therapy (CRRT) as a safer alternative to heparin. However, complex metabolic control to avoid side effects have generated discrepancies about its introduction into everyday practice. We aimed to compare both anticoagulation techniques in terms of efficacy, safety and feasibility. ⋯ These results suggest that the implementation of CVVHDF with RCA using concentrated citrate solutions prolongs filter lifetime, achieves a longer effective hemodiafiltration time and is a safe and feasible method.

Extracorporeal life support (ECLS) is a cardiopulmonary support system used for the treatment of severe cardiac and/or respiratory failure. Mortality is high partly because of the severity of the condition that requires support. The use of ECLS is generally associated with heavy sedation. The aim of this study was to demonstrate the feasibility of stopping sedation, allowing extubation of patients supported by ECLS. ⋯ This strategy could be a survival factor.

Th17/regulatory T cell imbalance in sepsis patients with multiple organ dysfunction syndrome: attenuated by high-volume hemofiltration.
We assessed the Th17 (T-helper cell)/Treg (Regulatory T cell) imbalance in sepsis patients with multiple organ dysfunction syndrome (MODS) and the clinical benefits of continuous high-volume hemofiltration (HVHF). ⋯ The level of Th17/Treg imbalance in sepsis is related to the occurrence and prognosis of MODS. High-volume hemofiltration can attenuate the Th17/Treg imbalance in sepsis patients, possibly by removing inflammatory mediators.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) may be life-saving in several clinical situations, but it is also one of the most invasive therapeutic procedures, with significant potential for life-threatening complications. Pulse pressure waves are typically very small or even absent at the onset of ECMO therapy, and will reappear with the improvement of cardiac function. A low pulse pressure may indicate low cardiac output due to heart failure during sustained ECMO support. A sudden loss of pulse pressure during ECMO therapy, however, may reveal complications like pericardial tamponade, hemothorax or pneumothorax. Near infrared spectroscopy (NIRS) has been shown to be useful in detecting cerebral and lower limb ischemic events during ECMO therapy and could furthermore improve differential diagnosis in the event pulsatility of the arterial pressure trace is lost. ⋯ Together with the appearance of a flat, non pulsatile arterial pressure trace as well as a reduction in mixed venous oxygen saturation the improvement of upper body rSO2 measured by NIRS enables timely recognition of complications that interfere with natural cardiac output during VA-ECMO.
