Pulmonary oedemas occurring during or after a blood transfusion appear as the most frequent serious immediate incidents in the French hemovigilance database. They include transfusion-associated circulatory overload (TACO) and transfusion-related acute lung injury (TRALI). TACO are a major cause of transfusion-related death in France. TRALI are more and more recognized and notified. In no case, pooled fresh frozen plasma (100 donations) treated with solvent-detergent were involved in French TRALI cases. A logigrame will allow hemovigilance officers to better classify pulmonary oedemas in e-fit, the French hemovigilance database.
