The impact of blood product ratios in massively transfused pediatric trauma patients

BackgroundFew studies have examined the impact of balanced resuscitation in pediatric trauma patients requiring massive transfusions. Adult data may not be generalizable to children.MethodsRetrospective analysis assessed patients seen at a level I trauma center between 2003 and 2010 aged ≤18 years requiring massive packed red blood cell (PRBC) transfusion, defined as transfusion of ≥50% total blood volume. After excluding mortalities in the first 24 hours, the impact of plasma and platelet ratios on mortality was evaluated.ResultsOf 6,675 pediatric trauma patients, 105 were massively transfused (mean age, 12.4 ± 6.3 years; mean Injury Severity Score, 25.8 ± 11.4; mortality rate, 18.1%). All deceased patients sustained severe head injuries. Plasma/PRBC and platelet/PRBC ratios were not significantly associated with mortality.ConclusionsIn this study, higher plasma/PRBC and platelet/PRBC ratios were not associated with increased survival in children. The value of aggressive blood product transfusion for injured pediatric patients requires further prospective validation.
