The August 2006 Awake! quotes on page 6, "Dr. Gariel Pedraza recently reminded his colleagues in Chile that "Transfusion is a poorly defined practice," one that makes it "difficult to...apply universally accepted guidelines."
So, Dr. Pedraza is saying that doctors do not know what they are doing?
His article is not about trauma and the need for blood transfusions. It's confined to low blood due to diseases. Yes, he's pro-JW, in that he's treated some JWs, and has used them as test objects to further his medical understanding of how low in hemoglobin a human can go. He is not, however, against using blood transfusions. In fact, he gives administers blood transfusions as this article shows: http://www.redclinica.cl/pmcsts/articulos/245/04UCI.pdf
