The objective of this study was to assess the relationship between the volume of red blood cells (RBCs) transfused and outcomes in children undergoing noncardiac surgery. ⋯ RBC transfusion is associated with an increased incidence of 30-day mortality and postoperative infections in children undergoing noncardiac surgery, and there is a correlation between the volume of red blood cells transfused and the incidences of adverse outcomes. Potential associations related to the reason to transfuse, the cause of the bleeding, or the actual blood products themselves need to be studied in further prospective trials.

The purpose of this study was to determine which variables are associated with different levels of transfusion for cesarean delivery. ⋯ Placenta previa was a risk factor associated with moderate transfusion, and pernicious placenta previa was the only modifiable prepartum risk factor independently associated with all transfused subgroups.

Clinical trials have shown that longer red blood cell (RBC) storage duration does not worsen outcomes; however, these studies included few RBCs near the end of the 42-day storage limit. We tested the hypothesis that these "oldest" RBCs are associated with adverse outcomes. ⋯ RBCs transfused in the last 7 days of their 42-day storage limit may be associated with adverse clinical outcomes in high-risk patients.

Recent animal studies suggest that transfusion of plasma from young donors reverses age-related neurologic and cardiac changes in older recipients. Associations between age of blood product donors and corresponding outcomes in recipients have not been studied in humans. Therefore, our primary objective was to examine this relationship between donor age and recipient outcomes among patients that received plasma during and after coronary artery bypass grafting (CABG) surgery. ⋯ We did not observe an association between donor age and recipient outcomes among patients who received plasma perioperatively while undergoing CABG surgery.

Zika virus (ZIKV) is an emerging arthropod-borne flavivirus transmitted by Aedes mosquitoes. Recent commentaries regarding ZIKV routes of transmission describe a potential transmission by transfusion. Herein, we report a probable case of transfusion-transmitted ZIKV infection through a platelet transfusion that was detected from postdonation information. ⋯ This is a case of probable transmission of ZIKV through blood transfusion. The patient had been transfused with the blood product from an infected donor, most likely in the incubation period after ZIKV infection but prior to clinical disease onset. This report emphasizes the importance of postdonation information and recipient investigations during outbreaks of potentially blood-borne infections.
