Pattern of acute blood transfusion reactions in Kano, North-Western Nigeria

Abstract

Background : Advancement in transfusion medicine has led to the use of large quantities of blood and blood components in modern clinical practice. The purpose of this study is to determine the pattern of acute blood transfusion reactions among adults in North-Western Nigeria. Materials and Methods: This was a descriptive observational study over a 3-month period that evaluated 302 blood transfusions in 180 consenting recipients in Aminu Kano Teaching Hospital. Data was analyzed using descriptive and inferential statistics, and P -values of ≤ 0.05 were regarded as significant. Results: The mean age of the recipients was 37.2 ± 13.7 (95% CI: 35.2 - 39.2) years. The incidence of acute transfusion reaction (ATRs) was 3.6%, out of which 3.3% were febrile non-hemolytic transfusion reaction (FNHTR) and 0.3% were acute allergic reaction (AAR). All the recipients that reacted presented clinically with fever and more than 90% of them had associated chills and/or rigors. There was a significant relationship between ATRs and history of previous transfusion (χ 2 = 4.12; P = 0.04) and stored blood of more than 3 days (χ 2 = 5.20; P = 0.02). Conclusion: Patients with previous history of transfusion should be monitored closely as they have a higher risk of developing transfusion reaction, and transfusion of blood stored for more than 3 days should as much as possible be avoided, especially in patients that have a potential risk of transfusion reaction.
