Transfusion

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.

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related morbidity and mortality. Anecdotally, TRALI patients have been treated with corticosteroids. However, evidence for its therapeutic rationale in TRALI is lacking. We determined the effects of corticosteroids on lung injury in a "two-hit" mouse model of antibody-mediated TRALI. ⋯ In a two-hit model of antibody-mediated TRALI, MPS attenuated the IL-6 host response, but failed to prevent the development of lung injury.

Multicenter Study Observational Study
Fresh-frozen plasma transfusion did not reduce 30-day mortality in patients undergoing cardiopulmonary bypass cardiac surgery with excessive bleeding: the PLASMACARD multicenter cohort study.
During on-pump cardiac surgery, hemorrhagic complications occur frequently. Fresh-frozen plasma (FFP) is widely transfused to provide coagulation factors. Yet, no randomized clinical trial has demonstrated its benefits on mortality. We assessed the relationship between therapeutic transfusion of FFP and 30-day mortality in cardiac surgery patients suffering from excessive bleeding in a prospective cohort study. ⋯ Among on-pump cardiac surgery patients experiencing excessive perioperative bleeding, there is no evidence of a beneficial impact of FFP transfusion on mortality.

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.

The aim of red blood cell (RBC) transfusion is to improve tissue oxygenation and relieve anemia-related symptoms in preterm infants. We sought to assess regional cerebral (rSO2 C) and mesenteric (rSO2 M) tissue oxygenation using a near-infrared spectroscopy (NIRS) method and vital signs (heart rate, arterial oxygen saturation, mean arterial blood pressure) in symptomatic preterm infants with anemia who received RBC transfusions. ⋯ RBC transfusion improved cerebral-mesenteric oxygenation and MCOR in symptomatic infants with anemia, independent of the transfusion duration.
