Blood transfusion after a BBL?

My biggest concern of a BBL sx is the need to get a blood transfusion afterwords. I know many people feel its safe and it can save your life; but after learning the pros/cons it is my personal decision not to have one regardless of the outcome. I am aware that rejecting one can result in death. Currently my hemo is at 13.5 and i'll work on bringing it up some more. But in case I end up needing a transfusion.. can an iron infusion or anything else be used in its place?
