From Transfusion Medicine to Patient Blood Management
The history of PBM is a story of discoveries, crises, and paradigm shifts in medicine’s relationship with blood.
From the earliest human transfusions to the consolidation of evidence-based strategies, each advance improved safety and reinforced the understanding that transfusion is a therapeutic intervention that requires careful indication.

From blood as a product to blood as part of the patient
The evolution of transfusion medicine improved safety and saved countless lives. PBM does not deny that history; it represents the next stage, in which transfusion is integrated into a broader strategy to preserve Blood Health.

Historical journey from transfusion medicine to Patient Blood Management
A visual summary designed to support quick understanding and connect the concept with the page content.
Transfusion safety and appropriate use of blood
Health crises such as HIV/AIDS demonstrated that transfusion carries real risks and requires traceability, scientific rigor, and appropriate indication. Later, clinical trials and PBM programs broadened the discussion: safety depends not only on making blood components safer, but also on deciding when transfusion is truly needed.
PBM emerges from this evolution: preserve the patient’s own blood, reduce avoidable blood loss, and use transfusion judiciously when its benefits outweigh its risks.
The website introduces the concept. The book explores its application in depth.
PBM Essencial: Transformando o Cuidado, Salvando Vidas explores in greater depth the historical path from transfusion medicine to PBM and its implications for modern practice, with references, clinical reasoning, and dedicated educational resources, particularly in Chapter 2.
PBM Essencial explores the topic in depth with protocols, algorithms, tables, references, and resources for study and consultation.
