Transfusion medicine reviews

Systematic reviews are accepted as a robust and less biased means of appraising and synthesizing results from high-quality studies. This report collated and summarized all the systematic review evidence relating to the diagnosis and management of trauma-related coagulopathy and transfusion, thereby covering the widest possible body of literature. We defined 4 key clinical questions: (1) What are the best methods of predicting and diagnosing trauma-related coagulopathy? (2) Which methods of clinical management correct coagulopathy? (3) Which methods of clinical management correct bleeding? and (4) What are the outcomes of transfusion in trauma? Thirty-seven systematic reviews were identified through searches of MEDLINE (1950-July 2010), EMBASE (1980-July 2010), The Cochrane Library (Issue 7, 2010), National Guidelines Clearing House, National Library for Health Guidelines Finder, and UKBTS SRI Transfusion Evidence Library (www.transfusionevidencelibrary.com). ⋯ Much more needs to be understood about how coagulopathy and bleeding in trauma are altered by transfusion practices and, most importantly, whether this translates into improved survival. There is a need for randomized controlled trials to answer these questions. The approach described in this report provides a framework for incorporating new evidence.

The advent of blood component storage revolutionized health care by allowing for a managed supply of transfusion quality blood products. During storage, blood components undergo a series of physiological changes that affect the product quality, which ultimately can interfere with the safety and efficacy of such products after transfusion. ⋯ Over the last decade, research on the feasibility of using microRNAs as biomarkers for various clinical manifestations and cellular pathologies has exploded. Here, we review the literature on blood cell microRNAs and discuss the potential of these molecules to act as measurable characteristics (product biomarkers) for stored blood component quality and safety.
