Ilove-Years ago I worked at a hospital as a go-fer. I would have to go to the lab to pick up blood for the patients. This required cross checking the name on the bag and so forth. The blood bags were labelled "bio-hazard", which was rather alarming. It wasn't all that common to have to pick blood up.
No cause for great alarm: ALL biological matter obtained from another human (urine, feces, blood, saliva, tears, hair, dandruff, etc) is considered as potentially-dangerous to others since it may serve as a vehicle for transmitting infectious agents, and requires special handling AS IF the person had an infectious disease: hence the designation of "bio-hazard". In the case of blood, it needs to be tested for the presence of pathogens (critters, eg virus that causes AIDs, etc) before use.
What surgeries/procedures/situations have been shown to be life-or-death decisions without blood?
I only know, currently, of trauma (car accident, gunshot wound, etc)...
What would be treatable exclusively with "no blood fractions" and with "no procedures using my blood"?
I don't think the answer is as cut-and-dry as you'd wish it to be, since the answer is highly dependent on the skill of the surgeon, the resources at their disposal, different outcomes amongst providers, etc. That's exactly WHY some surgeons specialize in bloodless surgery, even creating centers, eg:

Paintedtoenail: This is more the answer that I am looking for!! So, doctors would only transfuse if they knew the risks of transfusing were less than the risks of NOT transfusing, right?
Yeah, ALL medical decisions are based on risks vs benefits, and communicating that to the patient: that's the doctine of informed consent, since ultimately the patient has to make the decision of what care they wish to receive (it's their own body, and can refuse treatment EVEN IF the doctor doesn't agree with their decision HAS to respect and follow it).
