On-line products of substitution fluid by bicarbonate buffered dialysate permits virtually unlimited fluid volume exchange during continuous hemodiafiltration (CHDF) to critical care. In on-line hemodiafiltration (HDF), endotoxin free dialysate obtained using pyrogen cut filters is infused into the blood circuit, and HDF is automatically performed using the close-loop balancing system of the dialysis machine. ⋯ We performed on-line CHDF of the totally in 123 septic shock patients during a 5-year period and the mean survival rate was 54%. We concluded that on-line CHDF system is safe and effective at maintaining acute kidney injury with sepsis.

Accumulating evidences of underlining pathogenesis of sepsis have contributed to the therapeutic strategy for sepsis. Not only endotoxin and cytokine, but also signal transduction through Toll-like receptors could be a strategic target for the management of sepsis. ⋯ Although they were initially designed to remove endotoxin and cytokines respectively, they might eliminate unexpected mediators responsible for sepsis. Further elucidation of mechanism and randomized controlled studies are needed to establish the role of blood purification therapy in sepsis.

ADAMTS-13 is implicated in the pathophysiology of thrombotic thrombocytopenic purpura (TTP). Plasma exchange is thought to be effective through removal of a harmful substance or provision of a required material such as ADAMTS-13. As various methods are used to prepare plasma we determined the effects of storage and solvent detergent treatment on the ADAMTS-13 levels in plasma. ⋯ ADAMTS-13 levels are not significantly decreased by storage of plasma at room temperature for up to 48 h. Both CSP and SDP also contained essentially normal levels of ADAMTS-13 and therefore could be used for treatment of patients with TTP.

For peacekeeping and peace enforcing missions abroad the Netherlands Armed Forces decided to use universal donor frozen blood products in addition to liquid products. This article describes our experiences with the frozen blood inventory, with special attention to quality control. It is shown that all thawed (washed) blood products are in compliance with international regulations and guidelines. By means of the -80 degrees C frozen stock of red cells, plasma and platelets readily available after thaw (and wash), we can now safely reduce shipments and abandon the backup 'walking' blood bank, without compromising the availability of blood products in theatre.

Transfusion-related acute lung injury and transfusion-associated circulatory overload are important, life-threatening complications of transfusion. Each adversely impact hospital length of stay and cost of healthcare. TRALI is clinically indistinguishable from the adult respiratory distress syndrome but it has a more favorable prognosis. ⋯ TACO occurs in 1-8% of patients undergoing hip or knee arthroplasty. It is precipitated by positive fluid balance and high transfusion flow rates. TACO is characterized by respiratory distress and acute pulmonary edema.
