Summary

Cell salvage (CS) effectively minimizes the need for allogeneic blood transfusions during surgery. A new mathematical model predicts CS efficiency, showing it can significantly reduce blood loss when red cell recovery is optimal.

Area of Science:

  • Anesthesiology
  • Biomedical Engineering
  • Hematology

Background:

  • Cell salvage (CS) is a method to reduce allogeneic blood transfusions during surgery.
  • The efficiency of CS has not been previously modeled mathematically.
  • Existing methods like acute normovolemic hemodilution lack mathematical prediction models for efficiency.

Purpose of the Study:

  • To develop a mathematical model predicting hematocrit changes during cell salvage.
  • To define and quantify the efficiency of cell salvage based on maximum allowable blood loss (MABL).
  • To understand variables influencing cell salvage efficiency by comparing the model to clinical data.

Main Methods:

  • Developed a mathematical model accounting for hematocrit decrease due to blood loss and increase from washed red blood cell reinfusion.

  • Defined CS efficiency as MABL for a fixed blood volume and transfusion trigger.
  • Validated the model using hypothetical patient data (5000 mL blood volume, 45% presurgery hematocrit, 21% transfusion trigger) and real clinical data on red cell recovery rates.

    • Main Results:

    • The developed mathematical model can predict hematocrit decline during cell salvage.
    • For a hypothetical patient, the model calculated a MABL of 9600 mL with a 60% red cell recovery rate.
    • Clinical data showed an average CS red cell recovery rate of 57% with 20% variability.

    Conclusions:

    • A mathematical model for cell salvage (CS) has been successfully developed and validated against clinical data.
    • The model demonstrates that CS is a highly effective blood conservation strategy.
    • Optimizing red blood cell collection during CS is crucial for maximizing its effectiveness in avoiding transfusions.
