I want to give a bit more background information on these two authors before I move on to a couple points that their textbook raises.
Dr. Petra Seeber. She is a Jehovah's Witness doctor from Germany. He husband is a JW doctor as well - Dr. Matthias Lucas. They are the doctors who headed up the team to Haiti for disaster relief with the JW organization AidAfrique*, and they operate an Institute for Blood Management in Germany.
*I think that Wifibandit has a newspaper article archived, from Germany, that describes Dr. Seeber and Dr. Lucas' trip to Haiti...I will check. It is in pdf format.
Aryeh Shander. He is the doctor that keeps coming up whenever bloodless surgery and/or blood management is being talked about, especially in connection with the JWs. I have written a bit about him already, most notably his connection both to the WT's HLC and the US defense department concerning trauma research using blood alternatives.
To realize the impact that this particular doctor has on the world's blood supply, it is useful to know how far his reach extends. His reach goes far beyond his home base of the United States (Englewood).
Dr. Aryeh Shander attended the World Health Organization's Global Forum for Blood Safety: Patient Blood Management, March 2011, in Dubai, United Arab Emirates.

I am not sure which organization that Dr. Sander was representing at this United nations forum, but he does have affiliation with these 3 societies that were listed as "...key international nongovernmental and professional organizations associated with the clinical use of blood":

Medical Society for Patient Blood Management (MSBM),
Network for Advancement of Transfusion Alternatives (NATA),
Society for the Advancement for Blood Management (SABM)
Shander could very well be affiliated with other societies that were represented, but we also know that these three societies have strong and unmistakable links to the Hospital Information Services of the WT. Each one of these blood management societies have members that are HLC people. And JW doctors and JW nurses as well.
At the 2011 WHO conference in Dubai, Dr. Shander had the role of introducing Blood Management:

Session 1: Patient Blood Management (PBM) - Concept and Definition
Introduction, Rationale and Overview of PBM - Dr Aryeh Shander
When Dr. Shander spoke of the rationale underlying the principles of blood management, I wonder if he including an overhead and explanation of the illustration from his textbook that so simply and clearly shows that blood management is founded on "Holy Scriptures"?
