RESUMEN
Although case reports have been made regarding adverse transfusion reactions, few have been made regarding blood transfusions leading to cardiac arrest. Today, we present a case of a COVID-19 positive Bahraini male, triple vaccinated, transfused with packed red blood cell (pRBC) after finding out he has low haemoglobin levels (64 g/dl) after routine laboratory investigations. During the blood transfusion, he developed hypertension, tachycardia and tachypnoea. The patient went into cardiac arrest within a few minutes of this presentation. Return of spontaneous circulation was achieved, and the patient was managed as transfusion-associated circulatory overload (TACO) with a good overall outcome.Copyright © 2023, Bahrain Medical Bulletin.
