RESUMEN
【Objective】 To evaluate the clinical characteristics and risk factors of adverse transfusion reactions (ATR) in Chinese adults, and to provide evidence-based medical evidence for early prevention. 【Methods】 The controlled trial (CT) of risk factors for ATR in Chinese adults were collected through PubMed, Embase, Cochrane Library, CNKI, CMB, VIP and Wanfang database, and the retrieval time was from the establishment of those databases to January 31, 2021 Literature was selected and extracted by 2 researchers according to inclusion and exclusion criteria. Meta-analysis was performed by RevMan5.3 software. 【Results】 A total of 28 049 patients in 12 literature were included, 1 190 patients were included into the ART group and 26 859 into the non-ART group. Meta-analysis results showed that the incidence of ART was 1.63% (410/24 361), mainly allergic reaction (43.90%, 188/410) and non-hemolytic fever (40%, 164/410). Primary hematologic disease (OR=27.11, 95%CI=21.64~33.96, P 2 (OR=7.06, 95% CI=5.64~8.84, P30 min interval between blood issuing and transfusion (OR=3.40, 95% CI=2.88~4.00, P2, >30 min interval between blood issuing and transfusion, transfusion of plasma and cryoprecipitates, while transfusion of red blood cells/white blood cells/platelets was the protective factor.
