If your hospital/provider won’t agree to do it for you, there are independent (for pay) providers of this service.
It’s probably worth it.
“Auto-Transfusion is a process where patient receives his or her own blood instead of donor blood. This is a
common pratice for joint replacement surgeries and can be performed before, during or after surgeries.
During autologous blood donation patient donates his or her blood for own use, this process can commence
up to 5 weeks before surgery, which will be stored and reinfused as needed during or after the surgery. As
own blood is receptive to the body, it is an extremely safe way to help the patient in the recovery process.”
I think that will be something I will try when the time comes
