The use of irradiated RBCs in nontransplant patients is usually not prohibited, except in patients with renal dysfunction and hyperkalemia. At present, the possibility that irradiated RBC transfusion promotes the occurrence of deep vein thrombosis (DVT) remains unclear. Methods This retrospective cohort study was conducted on 251 trauma patients enrolled between January 2021 and April 2023 at the Second Affiliated Hospital of Chongqing Medical University. The cohort included 147 patients who were only transfused with nonirradiated RBCs (nonirradiation group) and 104 patients who were transfused with irradiated RBCs with or without nonirradiated RBCs (irradiation group). Multivariate logistic regression was used to analyze the risk factors for DVT in this population. Results The incidence of DVT was higher in the irradiation group than in the nonirradiation group (38.5% vs 22.4%, P<0.01). After adjusting for inconsistent variables, the results showed that irradiated RBC transfusion was a significant risk factor for DVT (odds ratio =2.16, 95% confidence interval=1.24 to 3.76; P<0.01). The incidence of DVT increased from 22.4% to 43.8% with the rising percentage of irradiated RBCs in total transfused RBCs (P =0.0248). The median storage days and total units of irradiated RBCs were not associated with an increased risk of DVT (odds ratio 0.05). Further subgroup analysis showed that the total volume, median storage days, and maximum storage days of transfused RBCs were not associated with the occurrence of DVT in this cohort, regardless of whether the irradiation group was included (all, P>0.05). Conclusions Irradiated RBC transfusion was associated with an increased risk of DVT in trauma patients in a percentage-dependent manner, and the total volume and longer storage duration of transfused RBCs were not associated with the incidence of DVT. The transfusion indications for irradiated RBCs should be strictly controlled to avoid unnecessary transfusion of irradiated RBCs to trauma patients.
