Comparative Study
Increased number of coagulation products in relationship to red blood cell products transfused improves mortality in trauma patients.
Recent data from military and civilian centers suggest that mortality is decreased in massive transfusion patients by increasing the transfusion ratio of plasma and platelet (PLT) products, and fibrinogen in relationship to red blood cell (RBC) products during damage control resuscitation and surgery. This study investigates the relationship of plasma:RBC, PLT:RBC, and cryoprecipitate:RBC transfusion ratios to mortality in massively transfused patients at a civilian Level 1 trauma center. ⋯ In the civilian setting, plasma, PLT, and cryoprecipitate products significantly increased 30-day survival in trauma patients. Future prospective randomized clinical trials are required to determine the optimal transfusion ratios.

Plasma and platelets (PLTs) are often transfused to correct mild to moderately abnormal laboratory values. Our objective was to reduce unnecessary plasma and PLT transfusions to nonbleeding patients by prospective triage and education of end users in evidence-based hemostasis and transfusion medicine practices. ⋯ Prospective triage and evidence-based transfusion practice education reduced unnecessary plasma and PLT transfusions and health care costs.

The 30-minute rule, whereby intact red blood cell (RBC) products may be returned to stock if returned to 4 degrees C storage within 30 minutes of issue, was established many years ago. It was based on observations that the core temperature of units of whole blood removed from storage temperatures of 1 to 6 degrees C, and left at room temperature, would reach 10 degrees C at between 45 minutes and 1 hour. ⋯ In view of our results, and the range of RBC products now available, it may be timely for blood services to review and reduce the 30-minute rule.

Transfusion-related acute lung injury (TRALI) is a serious, sometimes fatal complication of transfusion, attributed to white blood cell (WBC)-reactive antibodies present in the blood product. This study investigated incidence and etiology in the Netherlands. ⋯ TRALI is the most serious transfusion complication in the Netherlands, causing severe morbidity and mortality. Antibodies were found in the majority of the cases, but causality with proven incompatibility could be established in 21 cases (48%). Female FFP products were involved in 57% of proven alloimmune cases and would theoretically be prevented using male FFP only.

Multicenter Study
Variability on red blood cell transfusion practices among Brazilian neonatal intensive care units.
Guidelines for red blood cell (RBC) transfusions exist; however, transfusion practices vary among centers. This study aimed to analyze transfusion practices and the impact of patients and institutional characteristics on the indications of RBC transfusions in preterm infants. ⋯ The need of RBC transfusions in very-low-birth-weight preterm infants was associated with clinical conditions and birth center. The distribution of the number of transfusions during hospital stay may be used as a measure of neonatal care quality.
