Randomized Controlled Trial Multicenter Study
A multicenter, randomized, active-controlled study to investigate the efficacy and safety of intravenous ferric carboxymaltose in patients with iron deficiency anemia.
Many patients receiving oral iron for iron deficiency anemia (IDA) cannot tolerate or fail to respond to therapy, and existing intravenous (IV) iron formulations often require repeated administrations. Ferric carboxymaltose (FCM), a nondextran IV formulation, permits larger single doses. ⋯ Two 750-mg FCM infusions are safe and superior to oral iron in increasing Hb levels in IDA patients with inadequate oral iron response.

Postoperative nosocomial infection (PNI) is a severe complication in surgical patients. Known risk factors of PNI such as allogeneic blood transfusions (ABTs), anemia, and iron deficiency are manageable with perioperative intravenous (IV) iron therapy. To address potential concerns about IV iron and the risk of PNI, we studied a large series of orthopedic surgical patients for possible relations between IV iron, ABT, and PNI. ⋯ Despite known limitations of pooled observational analyses, these results suggest that very-short-term perioperative administration of IV iron, with or without rHuEPO, in major lower limb orthopedic procedures is associated with reduced ABT rates and LHS, without increasing postoperative morbidity or mortality.

Comparative Study Observational Study
Red blood cell transfusion in critically ill children (CME).
Red blood cell (RBC) transfusions are common in the pediatric intensive care unit (PICU). However, there are no recent data on transfusion practices in the PICU. Our objective was to determine transfusion practice in the PICU, to compare this practice with that observed 10 years earlier, and to estimate the compliance to the recommendation of a large randomized clinical trial, the Transfusion Requirements in Pediatric Intensive Care Unit (TRIPICU) study. ⋯ RBC transfusions are frequent in the PICU. Young age, congenital heart disease, low Hb level, severity of illness, and some organ dysfunctions are significant determinants of RBC transfusions in the PICU. Most first transfusion events were prescribed according to recent recommendations.

Patient blood management (PBM) has become a topic of intense interest; however, implementing a robust PBM system in a large academic hospital can be a challenge. In a joint effort between transfusion medicine and information technology, we have developed three overlapping databases that allow for a comprehensive, semiautomated approach to monitoring up-to-date red blood cell (RBC) usage in our hospital. Data derived from this work have allowed us to target our PBM efforts. ⋯ Our semiautomated auditing system allows us to quickly and comprehensively analyze and track blood usage throughout our hospital. Using this technology, we have seen improvements in our hospital's PBM.

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality. The majority of the literature involves adult patients. The main objective of this study was to characterize the demographic features, clinical presentation, patient outcomes, and antibody profiles of TRALI patients reported to the Canadian Blood Service (CBS) and to assess similarities and differences between adult and pediatric TRALI cases. ⋯ This study is the largest case series of reported TRALI cases in children. Crude modeling suggests that the incidence of TRALI in children is similar to that of adults. Although the numbers are small, there do not appear to be differences in presentation or outcome between adults and children with TRALI. TRALI is associated with significant morbidity and mortality and pediatricians need to consider this diagnosis in children who experience respiratory distress after transfusions.
