Pattern of Acute Adverse Transfusion Reactions in Patients With Burn Injuries: A Novel Initiative Towards Haemovigilance at the National Burn Centre of Pakistan

The transfusion of blood and blood components is a life-saving medical procedure, however, it is linked with adverse reactions to transfusions. Information about different types of adverse transfusion reactions (ATRs) will assist in their early identification and subsequent management, as well as in devising strategies to minimize the occurrence of adverse reactions related to blood component transfusion. The current study was therefore executed to analyze the pattern of ATRs in patients with burn injuries at a national burn center. This was a cross-sectional, prospective study involving an analysis of immediate ATRs from January 2020 to June 2021 (18 months). ATRs observed during the study period were documented and analyzed. During the study period, 2,220 units of blood and blood components were transfused to 1,075 burn patients (2.06 transfusions per patient). A total of 27 ATRs were recorded (1.21%). Allergic reactions were the commonest (55.55%) followed by febrile non-haemolytic transfusion reaction (37.03%). The mean volume of blood unit transfused, when the reactions were noted, was approximately 75 ml (range: 15-230 ml). The mean time at which transfusion reactions were noted was 17 min (range: 5-220 minutes). The ATRs were more common in patients with multiple transfusions compared to those receiving a single transfusion. The common adverse reactions were allergic and febrile non-haemolytic transfusion reactions. It is vital to report all transfusion reactions to the attached blood center and hospital transfusion committee (HTC) on standardized reporting forms. Continuous medical education through seminars and sensitization workshops will support consolidating haemovigilance systems.
