Since you are literally out of time (this being a holiday weekend), the best way you can prepare for this procedure is to be sure that you are clear about what you will and won't accept and be ready to communicate that to your surgeon . . . Read up on personal conscience choices -- the cell saver, erythropoietin, albumin, etc. so that you can communicate your wishes and make sure your "No Blood" advanced directive is completely filled out and copies are ready for the facility. If you've already made your surgeon aware of your "no blood" status in advance, he/she should be using solutions other than blood to "prime" the machine. If you've not communicated that to your surgeon, the earlier you do so the more the better so that the "team" can assist you in achieving the best outcome. If there is some type of heart surgery co-ordinator or "no blood" coordinator at the hospital, try to get in touch with them if possible to communicate your wishes as well.
