Reducing Blood Transfusion in Aortic Surgery: A Novel Approach

Area of Science:

• Cardiovascular Surgery
• Hematology
• Anesthesiology

Background:

• Coagulopathy management is critical in complex aortic surgery.
• Traditional approaches may lead to significant blood product transfusion.
• Novel strategies are needed to optimize patient outcomes.

Purpose of the Study:

• To evaluate a new algorithm for managing coagulopathy in aortic surgery.
• To compare outcomes between a novel algorithm and traditional methods.
• To assess the impact of autologous plasma and factor concentrates on transfusion requirements.

Main Methods:

• Retrospective analysis of 247 patients undergoing aortic surgery.
• Comparison of 158 patients (traditional algorithm) with 89 patients (novel algorithm).
• Novel algorithm utilized autologous platelet-rich plasma, fibrinogen, and prothrombin concentrates.
• Statistical analysis included univariate and multivariable robust regression.

Main Results:

• The novel algorithm group showed a significant reduction in red blood cell transfusion (3.5 vs 7.9 units, P < .001).
• Postoperative intubation time decreased from 42 to 12 hours (P < .001).
• Intensive care unit discharge time was reduced from 7 to 5 days (P < .001).
• Multivariable analysis confirmed significant reductions in red blood cell and overall blood product transfusions.

Conclusions:

• Utilizing autologous plasma and factor concentrates effectively manages coagulopathy in aortic surgery.
• This novel algorithm significantly reduces the need for blood product transfusion.
• The approach leads to shorter intensive care unit stays and improved patient recovery.
