Low-molecular-weight heparin and outcomes.

“blood” volume requires overtransfusion with whole blood, plasma, and other iso-oncotic products. Although “congestion” on this basis alone was once spoken of, it is a now a rare event. Until the pulmonary edema associated with the transfusion of packed RBCs and plasma derivatives (TRALI) is reported together with accurate infused volumes of crystalloid and colloid, and concurrent changes in patients’ weights, it is not going to be possible to distinguish ARDS from acute lung injury and TRALI.
