Comparative Study
Hemostatic function of buffy coat platelets in additive solution treated with pathogen reduction technology.
Pathogen reduction technologies (PRTs) may influence the hemostatic potential of stored platelet (PLT) concentrates. To investigate this, buffy coat PLTs (BCPs) stored in PLT additive solution (SSP+) with or without Mirasol PRT treatment (CaridianBCT Biotechnologies) were compared by functional hemostatic assays. ⋯ Mirasol PRT treatment of BCPs had a minimal influence on clot formation, whereas aggregation in the absence of RBCs and plasma was significantly reduced. Addition of RBCs and plasma increased agonist-induced responses resulting in comparable aggregation between PRT-BCP and CON-BCP. The clinical relevance for PLT function in vivo of these findings will be investigated in a clinical trial.

In January 2005, the Cord Blood Bank (CBB) at the Mexican Institute of Social Security initiated activities. Herein, we describe the experience generated during this period (January 1, 2005-December 31, 2009). ⋯ Although the experience presented herein is still limited and the period of analysis is still short, the results obtained during these 5 years are encouraging.

Comparative Study
Comparison of platelet transfusion as fresh whole blood versus apheresis platelets for massively transfused combat trauma patients (CME).
At major combat hospitals, the military is able to provide blood products to include apheresis platelets (aPLT), but also has extensive experience using fresh whole blood (FWB). In massively transfused trauma patients, we compared outcomes of patients receiving FWB to those receiving aPLT. ⋯ Survival for massively transfused trauma patients receiving FWB appears to be similar to patients resuscitated with aPLT. Prospective trials will be necessary before consideration of FWB in the routine management of civilian trauma. However, in austere environments where standard blood products are unavailable, FWB is a feasible alternative.

Transfusion-associated circulatory overload (TACO) is a frequent complication of blood transfusion. Investigations identifying risk factors for TACO in critically ill patients are lacking. ⋯ Volume of transfused plasma and the rate of transfusion were identified as transfusion-specific risk factors for TACO. Left ventricular dysfunction and fresh-frozen plasma ordered for the reversal of anticoagulant were strong predictors of TACO before the onset of transfusion.
