Despite my dislike of people who feel everyone else wants to know their opinion, you're gonna get mine, finally. i have been an advocate of BB banding for most of my med tech career, which started when some of you were in diapers. If you want stories where they prevented a mistransfusion let me know. We band everybody that has BB orders, with a (very) few exceptions. I understand the K.I.S.S. argument and when you find a system that everyone uses as intended every time, we can talk. Until then I'll like some redundancey. The fact that the band is labeled and applied to the patient at the bedside at the time of draw greatly increases my, and my staffs, comfort level that the unit of blood we return to the nurse will be given to the patient bearing the same number. Can the system be 'jobbed' and not provide any benefit? Sure, but since we've not had any transfusion accidents here in my 12 year tenure I think it does something good. We transfuse 20-22,000 units/year so we have able opportunity to screw up. As Mabel points out, though, any system is only as good as the people using it.
