From the Guidelines
Management of blood transfusion complications requires prompt recognition and specific interventions tailored to each reaction type, with a focus on minimizing morbidity, mortality, and improving quality of life. The most critical aspect of managing blood transfusion complications is the immediate identification and intervention for adverse reactions, as highlighted in the 2025 guidelines by the Association of Anaesthetists 1. This includes monitoring for signs of transfusion-associated circulatory overload (TACO), which is now the most common cause of transfusion-related mortality and major morbidity, characterized by acute or worsening respiratory compromise, cardiovascular changes, and evidence of fluid overload.
Key management strategies for complications of blood transfusion include:
- For acute hemolytic transfusion reactions, immediately stopping the transfusion, maintaining IV access with normal saline, and monitoring vital signs while providing supportive care.
- For febrile non-hemolytic reactions, slowing or temporarily stopping the transfusion and administering antipyretics such as acetaminophen.
- For allergic reactions, administering antihistamines like diphenhydramine; severe cases may require epinephrine and corticosteroids.
- For TACO, stopping the transfusion, positioning the patient upright, administering oxygen, and giving diuretics like furosemide (20-40mg IV) as recommended by the guidelines 1.
- For bacterial contamination, immediate transfusion cessation, blood cultures, and broad-spectrum antibiotics.
Prevention strategies are also crucial and include careful patient identification, appropriate blood product selection, and pre-medication for patients with previous reactions, as emphasized in both the 2025 1 and 2016 guidelines 1. Reporting all transfusion reactions to the blood bank is essential for investigation and future prevention. The use of positive patient identification, minimum patient identifiers, and alternative identification systems when necessary, as outlined in the 2025 guidelines 1, is vital in minimizing wrong-blood-in-tube events and risks of ABO incompatibility.

Management Strategies for Complications of Blood Transfusion
The management of complications arising from blood transfusion is crucial for ensuring patient safety. According to 2, understanding adverse reactions comprehensively is key to managing them effectively. This includes recognizing the causes, symptoms, and treatment methods of adverse blood transfusion reactions.
Types of Transfusion Reactions
Transfusion reactions can be categorized into immediate and delayed reactions based on the time of onset. Immediate reactions require timely identification and immediate cessation of transfusion, as highlighted in 3. Delayed reactions may present with nonspecific signs and symptoms, necessitating vigilance to distinguish them.
Diagnostic Approach and Management
The diagnostic approach and management of acute transfusion reactions are critical. As noted in 4, any symptom occurring within 24 hours of a blood transfusion should be considered a transfusion reaction and referred to the hemovigilance reporting system. The initial management requires early identification, immediate interruption of the transfusion, early consultation of relevant departments, and fluid resuscitation.
Prevention of Transfusion Reactions
Preventing transfusion reactions is also a key strategy. According to 4, the best way to prevent transfusion reactions is to avoid unnecessary blood transfusions and maintain a transfusion-restrictive strategy. This approach, combined with improved hemovigilance and evidence-based algorithms for transfusion, can lead to a decrease in the incidence of serious transfusion reactions, as mentioned in 3.
Common Transfusion Reactions
Common transfusion reactions include febrile non-hemolytic transfusion reactions (FNHTRs), allergic reactions, and others. As observed in 5, FNHTRs and allergic reactions are among the most common transfusion reactions, particularly in pediatric and surgical patients. Understanding the pattern of these reactions can help in their management and prevention.
Key Considerations
- Early identification and management of transfusion reactions are critical for patient safety.
- Avoiding unnecessary blood transfusions can help prevent transfusion reactions.
- Improved hemovigilance and evidence-based transfusion algorithms are essential for reducing the incidence of serious transfusion reactions.
- Recognizing the causes, symptoms, and treatment methods of adverse blood transfusion reactions is vital for effective management, as emphasized in 2 and 3.
