That is a comprehensive post, Wonder.
This part is interesting:
Specific risk of the strategy of non-transfusion
It is estimated that non-transfusion strategy adds a mortality risk of 0.5-1.5% to the patient’s own (The American Journal of Medicine, February 1993). This means that for every 100 patients undergoing bloodless surgery strictly, there is one that dies needlessly.
This figure is well above the surgical-anaesthetic risk without the restriction of blood. According to recent statistics (Anaesthesia, 56 (12): 1141-1153) in 10,000 anaesthetics:
There are 8.8 cases of perioperative death
There are 0.5 cases of perioperative coma
There are 1.4 deaths associated with anaesthesia
That is, if the possibility of death or coma is 0.5-8.8 per 10,000 operations, the strategy of non-transfusion-risk places this 50-150/10.000 interventions. This means that the risk is 20-100 times higher.
These statistics have been made in different years, and therefore medical technology may have improved this situation. However, we have not found in medical literature most recent statistics in terms of morbidity and mortality associated with strict non-transfusion strategy.
