Integrated strategies for allogeneic blood saving in major elective surgery.

Area of Science:

• Transfusion Medicine
• Surgical Patient Care

Background:

• Allogeneic red blood cell concentrate (RBCc) use is common in major surgery but can impact patient outcomes.
• Strategies to minimize allogeneic RBCc transfusions are crucial for improving surgical patient safety.

Purpose of the Study:

• To evaluate an integrated strategy for reducing allogeneic RBCc usage in major elective surgery.
• To assess the impact of autologous blood collection and supplementation on transfusion practices.

Main Methods:

• Implementation of a comprehensive patient evaluation and supplementation strategy.
• Integration of autologous blood collection and preservation for elective surgeries since 2008.
• Analysis of transfusion data from 2010 to assess changes in RBCc usage.

Main Results:

• Total autologous RBCc unit usage increased by 2.2-fold.
• Use of "not stored" autologous RBCc units rose by 2.4-fold.
• Allogeneic RBCc unit transfusion was reduced by 65%.

Conclusions:

• The integrated autologous blood strategy effectively reduced reliance on allogeneic RBCc transfusions.
• Utilizing fresher, autologous blood may mitigate complications associated with immunomodulation and metabolic dysregulation.
• This approach offers a viable method for optimizing blood management in major surgical procedures.
