Transfusion
-
Posttransfusion purpura (PTP) is a serious transfusion complication resulting in sudden thrombocytopenia with bleeding. The study's objective was to assess PTP occurrence and potential risk factors among the inpatient US elderly, ages 65 and older, during 2011 through 2012. ⋯ Our population-based study suggests a substantially higher PTP risk with PLT-containing transfusions. The study also suggests increased PTP risk with greater number of units transfused as well as the importance of underlying health conditions and prior recipient alloimmunization for PTP occurrence among the elderly.

We evaluated the hemostatic efficacy of H12-(adenosine 5'-diphosphate [ADP])-liposomes in the setting of active liver bleeding in rabbits with dilutional thrombocytopenia after massive transfusion. ⋯ H12-(ADP)-liposomes might be a safe and effective therapeutic tool during damage control surgery for trauma patients with acute thrombocytopenia and massive bleeding.

Comparative Study Clinical Trial
Comparison of three noninvasive methods for hemoglobin screening of blood donors.
To prevent phlebotomy of anemic individuals and to ensure hemoglobin (Hb) content of the blood units, Hb screening of blood donors before donation is essential. Hb values are mostly evaluated by measurement of capillary blood obtained from fingerstick. Rapid noninvasive methods have recently become available and may be preferred by donors and staff. The aim of this study was to evaluate for the first time all different noninvasive methods for Hb screening. ⋯ Noninvasive Hb tests represent an attractive alternative by eliminating pain and reducing risks of blood contamination. The main problem for generating reliable results seems to be preanalytical variability in sampling. Despite the sensitivity to environmental stress, all methods are suitable for Hb measurement.

Review Meta Analysis
Low-risk transfusion-related acute lung injury donor strategies and the impact on the onset of transfusion-related acute lung injury: a meta-analysis.
Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality. In the past decade blood banks have implemented low-risk TRALI donor strategies, including a male-only donor policy for plasma-containing blood products to prevent onset of TRALI. We performed a meta-analysis to determine whether use of low-risk TRALI donor strategies for plasma indeed reduces onset of TRALI. ⋯ The introduction of low-risk TRALI donor strategies for plasma-containing products results in a reduction of TRALI.

Randomized Controlled Trial Multicenter Study Comparative Study
Transfusion of fresh-frozen plasma in critically ill patients with a coagulopathy before invasive procedures: a randomized clinical trial (CME).
Prophylactic use of fresh-frozen plasma (FFP) is common practice in patients with a coagulopathy undergoing an invasive procedure. Evidence that FFP prevents bleeding is lacking, while risks of transfusion-related morbidity after FFP have been well demonstrated. We aimed to assess whether omitting prophylactic FFP transfusion in nonbleeding critically ill patients with a coagulopathy who undergo an intervention is noninferior to a prophylactic transfusion of FFP. ⋯ In critically ill patients undergoing an invasive procedure, no difference in bleeding complications was found regardless whether FFP was prophylactically administered or not.
