Cryoprecipitate for the treatment of life‐threatening hemorrhage in children

Abstract Background Hypofibrinogenemia is an important risk factor for poor outcomes in children with severe bleeding. There is a paucity of data on the impact of cryoprecipitate transfusion on outcomes in pediatric patients with life‐threatening hemorrhage (LTH). Study Design and Methods This secondary analysis of a multicenter prospective observational study of children with LTH investigated subjects who were categorized by receipt of cryoprecipitate during their resuscitation and according to the etiology of their bleeding: trauma, operative, and medical. Bivariate analysis was performed to identify variables associated with 6‐h, 24‐h, and 28‐day mortality. Cox Hazard regression models were generated to adjust for potential confounders. Results Cryoprecipitate was transfused to 33.9% (152/449) of children during LTH. The median (Interquartile range) time to cryoprecipitate administration was 108 (47–212) minutes. Children in the cryoprecipitate group were younger, more often female, with higher BMI and pre‐LTH PRISM score and lower platelet counts. After adjusting for PRISM score, bleeding etiology, age, sex, RBC volume, platelet volume, antifibrinolytic use and cardiac arrest, cryoprecipitate administration was independently associated with lower 6‐h mortality, Hazard Ratio (95% CI), 0.41 (0.19–0.89), ( p = 0.02) and 24‐h mortality, Hazard Ratio (95% CI), 0.46 (0.24–0.89), ( p = 0.02). Conclusion Cryoprecipitate transfusion to children with LTH was associated with reduced early mortality. A prospective randomized trial is needed to determine if cryoprecipitate can improve outcomes in children with LTH.
