Abstract
BACKGROUND
Low-titer group O whole blood (LTOWB) use has been associated with improved survival and less blood transfusions in adult trauma patients. Its use in pediatric trauma has been shown to be safe when using leukoreduced, LTOWB with anti-A, anti-B antibody titers of <1:50. We set out to evaluate the safety, hemostatic potential, and impact on pediatric outcomes at a center using non-leukoreduced, LTOWB with anti-A, anti-B antibody titers of <1:200.
METHODS
Patients younger than 18 years, who received emergency-release, uncrossed matched blood, and presented to our trauma center from November 2017 to April 2021 were included. Patients were divided into those receiving any LTOWB and those receiving only RBC and or plasma (COMP). Primary outcome was 30-day survival.
RESULTS
One hundred sixty-four patients received emergency release blood products. Of these, 73 received at least one unit of LTOWB. The LTOWB group were younger (14 years vs. 13 years), more likely to be male (87% vs. 49%), and to have sustained penetrating trauma (44% vs. 23%); all p < 0.05. Low-titer group O whole blood patients received more blood than their COMP counterparts prior to arrival. Serial hemolysis panels (K+, bilirubin, LDH, haptoglobin) obtained at 24 hours, 48 hours, and 72 hours were similar between groups; all p > 0.05. There was no difference in survival by univariate analysis but after adjusting for inverse probability of treatment weights there was an observed association between WB administration and improved survival, with an odds ratio of 2.48 (1.15–5.47).
CONCLUSION
Non-leukoreduced, LTOWB in anti-A/anti-B antibody titers of <1:200 appear safe in children and adolescents. While patients receiving LTOWB had more evidence of shock, higher torso injury severity, and received more prehospital blood products, there may be a mortality benefit with whole blood. Larger, multicenter studies are needed.
