Patient Blood Management
PBM is seen as a new paradigm in transfusion medicine
The aim of this workshop is
- to explain the rationals and fundamentals of PBM
- to help to implement this strategy
- to improve patients‘ outcome and to reduce costs

What is patient blood management?
• PBM views a patient‘s own blood as a valuable and uniquenatural resource that should be conserved and managedappropriately.
• PBM employs a patient-specific perioperative multi-• PBM employs a patient-specific perioperative multi-
disciplinary, multimodal team approach to optimising, conserving and managing patients own blood.
• PBM aims to identify patients at risk of anemia and provide a managed plan aimed at reducing or eliminating the need for
allogeneic transfusion with an acceptable risk of anemia.

WHA63.12 adoptedby resolution May 21, 2010:
„Bearing in mind that patient blood management means that before surgery
every reasonable measure should be taken to optimize the patient’s own blood volume, to minimize the patient’s blood loss and to harness and optimize the patient-specific physiological tolerance of anaemia following WHO’s
guide for optimal clinical use (three pillars of patient blood management)“

The AUSTRALIAN RED CROSS discarded 33,600liters of donated blood as the result of fears that it
was contaminated with dengue fever following an
outbreak of the disease in northern Queensland inoutbreak of the disease in northern Queensland in
late 2009 and 2010, according to a report in the
Sunday Herald Sun.
That loss ... accounted for about 7% of its overall
blood supply.

Ansteckungsweg über das Blut können Bluttransfusionen
Alzheimer übertragen?
Alzheimerforscher haben Hinweise darauf gefunden, dass die Demenzerkrankung
via Bluttransfusionen übertragen werden könnte. Unklar ist, in welcher
Konzentration die mutmaßlichen Erreger ansteckend sein könnten.
Amerikanischen Neurowissenschaftlern soll es in einem Tierversuch gelungen
sein, Alzheimer auf dem Blutweg von einer kranken Maus auf eine gesunde zu
übertragen. Die Ergebnisse wurden allerdings noch nicht in einem seriösen
Fachblatt veröffentlicht. Der Molekularbiologe Christian Haass von der Universität
Focus online Sonntag, 12.02.2012, 11:05
Fachblatt veröffentlicht. Der Molekularbiologe Christian Haass von der Universität
München sagte FOCUS, es könnte möglich sein, dass die Ansteckung über
Eiweißmoleküle im Blut verlaufe. …
Allerdings sei eine Altersbegrenzung für Blutspender „vielleicht sinnvoll“.
Der Präsident des Robert Koch-Instituts, Reinhard Burger, forderte im FOCUS, die
Ergebnisse der Studie rasch zu überprüfen. Noch sei unbekannt, in welcher
Konzentration die mutmaßlichen Erreger zur Ansteckung führen könnten. Voreilig
ältere Menschen von der Blutspende auszuschließen, hält Burger für unlogisch und
riskant, da sonst Versorgungsengpässe drohten. Patienten würden dann
womöglich ohne lebensrettende Bluttransfusion bei Operationen oder nach
Unfällen sterben

Intraoperative Transfusion of 1 U to 2 U Packed Red Blood Cells Is Associated with Increased 30-Day Mortality, Surgical-Site
Infection, Pneumonia, and Sepsis in General Surgery Patients
Propensity and risk adjusted odds ratios (95% CI) for 30-day mortality and morbidity by level of intraoperative transfusion. Both morbidity and mortality risks were substantially increased after only 1 U RBC transfusion
intraoperatively and continued to increasewith increasing units. Circles, mortality; squares, morbidity.
