Some studies in both children and adults have shown a mortality benefit for the use of low titer group O whole blood (LTOWB) compared with component therapy for traumatic resuscitation. Although LTOWB is not widely available at pediatric trauma centers, its use is increasing. We hypothesized that in children who received whole blood after injury, the proportion of whole blood in relation to the total blood product resuscitation volume would impact survival.
