What is preoperative autologous blood donation (PABD)?
PABD refers to the donation by a patient of
their own blood before an operation for storage and possible transfu-sion
intraoperatively or postoperatively. A national multi-center study in 1987
revealed that as much as 10% of all blood transfused for elective surgery could
be obtained by PABD. Clearly, the driving force behind the increased inter-est
in PABD at this time was fear of transfusion trans-mission of viruses,
particularly human immunodeficiency virus (HIV). Use of PABD peaked in 1992,
when it provided 8.5% of all units of blood collected in the United States. Use
of PABD has declined in recent years. In 1999, 4.7% of all units collected, and
3% of all units of red blood cells trans-fused, were provided by PABD. PABD has
clearly been shown to reduce patient exposure to homologous blood.
