In addition, 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 risk factors. A total of 13 studies met the inclusion criteria.RESULTS: We summarized and analyzed the potential risk factors of TRALI for critical patients in 13 existing studies. Host-related factors were age (odds ratio [OR] 1.16 [95% CI 1.08–1.24]), female sex (OR 1.26 [95% CI 1.16–1.38]), tobacco use status (OR 3.82 [95% CI 1.91–7.65]), chronic alcohol abuse (OR 3.82 [95% CI 2.97–26.83]), positive fluid balance (OR 1.24 [95% CI 1.08-1.42]), shock before transfusion (OR 4.41 [95% CI 2.38–8.20]), and American Society of Anesthesiologists (ASA) score of the recipients (OR 2.72 [95% CI 1.43–5.16]). The transfusion-related factors were the number of transfusions (OR 1.40 [95% CI 1.14–1.72]) and units of fresh frozen plasma (OR 1.21 [95% CI 1.01–1.46]). The device-related factor was mechanical ventilation (OR 4.13 [95% CI 2.20–7.76]).CONCLUSIONS: The risk factors that were positively correlated with TRALI in this study included number of transfusions and units of fresh frozen plasma. 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 results suggest that host-related risk factors may play a more important role in the occurrence and development of TRALI than risk factors related to blood transfusions.
