Drs. Janet Lee and Darrell Triulzi each present from the 2016 UPMC Department of Medicine Grand Rounds. Dr. Lee provides a brief introduction on red cell “storage lesion” and surrounding controversy, discusses aged RBC transfusion and the disruption in iron handling and homeostasis, and the disruptions in nitric oxide availability. Dr. Triulzi discusses the red cell storage criteria and reviews some clinical data trials.
Educational objectives:
Upon completion of this activity, participants should be able to:
- Increase understanding of normal iron homeostasis in humans
- Improve diagnostic skills in identifying intra- and extravascular hemolysis
- Implement evidence-based RBC transfusion guidelines
