"It is estimated that the incidence of adverse outcome is 18:100 000 red blood cells issued for children aged less than 18 years and 37:100 000 for infants. The comparable adult incidence is 13:100 000. In order to decrease the risks associated with transfusion of blood products, various blood-conservation strategies can be utilized. Modalities such as acute normovolemic hemodilution, hypervolemic hemodilution, deliberate hypotension, antifibrinolytics, intraoperative blood salvage, and autologous blood donation are discussed and the pediatric literature is reviewed."

"In the USA red blood cell transfusions, for instance, are given to an estimated 3–4 million patients per year. However, the accepted benefits of transfusion do not come without harm. Acute transfusion reactions have been estimated to occur in almost one-fifth of total transfusions, with serious reactions in approximately 0.5%."

Now, I am not saying that there aren't risks. Nor am I saying that alternatives to blood should not be researched and implemented. Any progress is good in my opinion. But let us not try to paint some dismal picture that blood transfusion is bad. Your source details that we are specifically talking about "some clinical situations" and that was regarding administration to the "critically ill" (tinmouth 2006). Your video also describes a 2008 study where blood transfusions were associated with increased morbidity and mortality in icu, trauma, and surgery. Both of these studies were very clearly only making conclusions about adults. And the last citation is a 2009 review that suggested in nearly 60% of cases blood transfusion was not beneficial.
This last study is unclear whether we are again talking about adults, or what studies were reviewed.
But, uncontested in your video is that in some instances, blood transfusion is both necessary and beneficial. If we are, moving towards better understanding the situations where blood transfusion is helpful vs. Harmful, that is fantastic. But no source has suggested that JW s got it right, no source suggests that all blood transfusion should be refused, and no source suggests that blood transfusion is bad (especially not because god said so).
Should we be critical of an accepted practice such as blood transfusion...you betcha. Should we continue to strive for better outcomes, both with blood products and alternatives? Hell yeah. Should we for one moment side with religion over the best available evidence when a child's life hangs in the balance? Nope.
