if you know you have a major surgery coming up that may require a blood transfusion you can donate your own blood for your own use. I believe you can donate a couple of units a week apart or so and two weeks before the surgery.
Retired Maxillofacial surgeon here. I used to give the option to patients when doing double jaw surgery which has the potential for significant blood loss.
Used to work in surgery and think family also donated on a rare occasion, one that had same blood type. Of course they had to go to larger city that had the blood center.
