7. Adverse Effects of Transfusion

7.13 Transfusion-associated Dyspnoea

Only a minority of transfusion reactions are associated with predominantly respiratory features however these are some of the most serious transfusion-related adverse events. Included in this group are TACO, TRALI and allergic reactions, particularly of the more severe type.

The term transfusion-associated dyspnoea (TAD) is used by haemovigilance programmes to record events with significant respiratory distress, occurring within 24 hours of transfusion, that do not meet the criteria of TRALI, TACO or allergic reaction nor are explained by the patient’s underlying condition.
