And there is no clinically effective treatment plan for TRALI. The aim of this study was to systematically summarize the literature on risk factors for TRALI in critical patients.Methods: Electronic searches (up to March 2020) were performed in the Cochrane Library, Web of Knowledge, Embase, and PubMed databases. We included studies reporting on the risk factors of TRALI for critical patients and extracted the risk factors. Finally, thirteen studies met the inclusion criteria.Results: We summarized and analyzed the potential risk factors of TRALI for critical patients in 13 existing studies. The host-related factors were age (odds ratio (OR) [95% confidence interval] = 1.16 [1.08-1.24]), female sex (OR = 1.26 [1.16-1.38]), tobacco use status (OR = 3.82 [1.91-7.65]), chronic alcohol abuse (OR = 3.82 [2.97-26.83]), positive fluid balance (OR = 1.24 [1.08-1.42]), shock before transfusion (OR = 4.41 [2.38-8.20]), and ASA score of the recipients (OR = 2.72 [1.43-5.16]). The transfusion-related factors were the number of transfusions (OR = 1.40 [1.14-1.72]) and fresh frozen plasma (FFP) units (OR = 1.21 [1.01-1.46]). The device-related factor was mechanical ventilation (OR = 4.13 [2.20-7.76]).Conclusions: The risk factors for TRALI in this study included Number of transfusions and FFP units were positively correlated with TRALI. Age, female sex, tobacco use, chronic alcohol abuse, positive fluid balance, shock before transfusion, ASA score and mechanical ventilation may be potential risk factors for TRALI. Our study suggests that host-related risk factors may play a more important role in the occurrence and development of TRALI than blood transfusion-related risk factors. ER -
