Turkish Journal of Anaesthesiology and Reanimation, 51(2), 143-146. https://doi.org/10.5152/TJAR.2023.221332667-6370https://doi.org/10.5152/TJAR.2023.22133https://hdl.handle.net/20.500.12511/11053A 73-year-old, 104 kg female patient was hospitalised for debulking and low anterior colon resection operations. Anaphylactoid symptoms devel-oped when administering erythrocyte suspension and fresh frozen plasma. Through the immediate haematology department consultation, it was found that the patient might possibly have immunoglobulin A deficiency. Immunoglobulin A level was found to be very low in the patient’s blood sample, which was sent intraoperatively to verify the diagnosis. This case report discusses a sudden anaphylactic reaction that occurred as a result of a blood transfusion in a previously undiagnosed immunoglobulin A deficiency.enAttribution 4.0 Internationalinfo:eu-repo/semantics/openAccessAnaphylaxisBlood ProductsImmunoglobulin APerioperative CareTransfusionArticle51214314610.5152/TJAR.2023.22133N/A0009924492000102-s2.0-8516042915037140580Q3
