BACKGROUND With an ongoing demand for transplantable organs,optimization of donor management protocols,specifically in trauma populations,is important for obta-ining a high yield of viable organs per *** management of brain-dead potential organ donors(BPODs)is controversial,leading to heterogeneous clinical management *** studies have shown that when levo-thyroxine was combined with other treatments,including steroids,vasopressin,and insulin,BPODs had better organ recovery and survival outcomes were increased for transplant *** To determine if levothyroxine use in combination with steroids in BPODs increased the number of organs donated in trauma *** A retrospective review of adult BPODs from a single level 1 trauma center over ten years was *** criteria included patients who were not solid organ donors,patients who were not declared brain dead(donation after circulatory death),and patients who did not receive steroids in their hospital *** and steroid administration,the number of organs donated,the types of organs donated,and demographic information were *** analyses were performed with P0.05).In the ST/LT group,68.1%(n=47)donated a high yield(3-5)of organ types per donor compared to 42.1%(n=8)in the ST group(P=0.038).There was no difference in the total number of organ types donated between the groups(P=0.068).CONCLUSION This study suggests that combining levothyroxine and steroid administration increases high-yield organ donation per donor in BPODs in the trauma patient *** to this study include
