Background. Adverse reactions to transfusion are defined as the occurrence of any adverse event during or after the transfusion of blood or any of its components. Objective: To determine the prevalence of post-transfusional adverse reactions to the blood components administered at the High-Specialty Regional Hospital of "Ciudad Salud", in Chiapas, Mexico, in the period 2013 to 2017. Methods: A descriptive and retrospective study was conducted. The reports of the transfusion reactions occurred during the study period were reviewed. The reactions were classified according to the standards and recommendations recognized by the American Association of Blood Banks. Results: A total of 38 adverse transfusion reactions were reported, with a prevalence of 0.38%; the erythrocyte concentrate was the blood component that elicited the most adverse reactions to transfusion, in 55.3%. The allergic reaction was the most frequent type of reaction, in 60.5% (n = 23). (Hosp Med Clin Manag. 2018;11:126-9) Corresponding author: Roberto Alejandro Sánchez-González, roasago@gmail.com
