We describe the implementation and impact of a patient blood management program (PBMP) in an Australian teaching hospital. ⋯ This is the first tertiary hospital in Australia to establish a multidisciplinary multimodal PBMP. Interventions across disciplines resulted in decreased use of RBC units especially in orthopedic and cardiothoracic surgery. Continuing education and feedback to specialties will maintain the program, improve patient outcomes, and decrease the transfusion rate.

Human red blood cells (RBCs) can be stored for up to 42 days under controlled conditions. Physical and chemical changes occur during RBC storage, altering their function. This study links stored cell mechanical changes with hemodynamic functional alterations upon transfusion. ⋯ The reduced cell deformability due to RBC "storage lesions" caused pathologic changes in microvascular hemodynamics, endothelial cell mechanotransduction, and RBC dynamics. Thus, the mechanical changes of blood-banked cells can limit transfusion ability to achieve its intended goal.

Low levels of hemoglobin (Hb) are not rare in patients who refuse blood components but this case is unique due to the severity of anemia and the possibility that her previous episode of acute normovolemic hemodilution has influenced her outcome. ⋯ This case is an example of the resilience of the human body in an extreme circumstance. It might be the most severe case of anemia that a person has survived without any sequelae.

Studies have shown heterogeneity in red blood cell transfusion practices. Although plasma transfusion is common in intensive care, there are no data on plasma transfusion practices in pediatric critical care units. ⋯ More than two-thirds of responding pediatric critical care physicians prescribe plasma transfusions for nonbleeding critically ill children. Additionally, there is a significant variation in transfusion practice patterns with respect to plasma transfusion thresholds.
