A systematic review of randomized controlled trials and observational studies assessing platelet (PLT) transfusion therapy identified gaps in the descriptions of trial design, variables of the PLT products transfused, and outcomes. We aimed to systematically develop a reporting guideline to aid in designing, reporting, and critiquing PLT trials. ⋯ Use of the Delphi method was successful in finding consensus on items to include in reports of a clinical PLT transfusion study. The final checklist and explanatory guide will be useful for authors and editors to improve the reporting of PLT transfusion trials.

Extracorporeal membrane oxygenation (ECMO) provides lifesaving hemodynamic and respiratory support to neonatal and pediatric patients with a variety of congenital or acquired cardiopulmonary defects. Successful ECMO support requires close collaboration among multiple services, including critical care medicine, perfusion, and transfusion medicine services. Neonatal and pediatric ECMO patients require significant transfusion support, both at the time of cannulation and after the ECMO circuit has been established, often with little advance notice. ⋯ In this article, we describe our protocol for transfusion support for ECMO and potential ECMO patients, which was developed to address a number of issues, including identifying and stratifiying ECMO candidate patients, streamlining the ordering and communication processes, and improving blood product turnaround times and availability. Additional measures of quality improvement are also discussed. As the number of centers performing ECMO procedures remains high, we believe that our experience may be of interest to our colleagues in transfusion medicine and critical care.

Comparative Study Clinical Trial
Transfusion of banked red blood cells and the effects on hemorrheology and microvascular hemodynamics in anemic hematology outpatients.
The aim of this study was to investigate the effects of red blood cell (RBC) transfusion on the hemorrheologic properties and microcirculatory hemodynamics in anemic hematology outpatients receiving 2 to 4 RBC units of either "fresh" (leukoreduced storage for less than 1 week) or "aged" (leukoreduced storage for 3-4 weeks) RBCs. ⋯ Storing leukoreduced SAGM-suspended RBCs for 3 to 4 weeks did not affect their ability to improve hemorrheologic properties and microcirculatory hemodynamics in our small group of anemic hematology outpatients. Larger studies are needed to confirm this finding.
