Background: The administration of blood products to injured children has been recognized as a potential risk of nonoperative management. The purpose of this study was to evaluate blood utilization in the management of solid organ injuries in pediatric blunt abdominal trauma victims.
Methods: One hundred sixty-one children (< or =16 years old) with solid organ injuries over an 8-year study period (1990 through 1997) were identified from the trauma registries at 2 urban regional trauma centers.
Results: Mean age of the study patients was 7.9+/-0.4 years, 95 (59%) were boys, and their mean injury severity score (ISS) was 17.8+/-1.2. Patients were divided into 4-year study cohorts (1990 through 1993 and 1994 through 1997) to examine changes in operative management and blood utilization. For each time period examined, those treated nonoperatively received fewer blood transfusions (46% v 9% and 44% v 13%, P<.05 by Fisher's Exact test), and the hospital length of stay was shorter (12.3+/-2.1 v 5.0+/-0.7 and 7.8+/-1.9 v 4.2+/-0.4 days, P<.0001 by analysis of variance/Scheffe's) compared with the laparotomy cohort.
Conclusions: The appropriate nonoperative management of injured children actually reduces the risks of receiving blood transfusion and decreases the length of hospital stay compared with aggressive operative intervention. Blood transfusion should be reserved only for those injured children with solid organ injuries who are hemodynamically unstable.
