Autotransfusion following cardiac operations: a randomized, prospective study.

R L Thurer, B W Lytle, D M Cosgrove

    The Annals of Thoracic Surgery
    |June 1, 1979
    PubMed
    Summary

    This study assessed autotransfusion of shed mediastinal blood after cardiac surgery. While clinically safe, it did not significantly reduce banked blood use in patients already undergoing aggressive blood conservation.

    Area of Science:

    • Cardiovascular Surgery
    • Transfusion Medicine
    • Patient Blood Management

    Background:

    • Cardiac surgery often necessitates significant blood transfusions.
    • Multifaceted blood conservation strategies are crucial for patient outcomes.
    • Autotransfusion of shed mediastinal blood is a potential component of these strategies.

    Purpose of the Study:

    • To evaluate the safety and effectiveness of collecting and retransfusing postoperatively shed mediastinal blood.
    • To determine if this technique further reduces banked blood use in cardiac surgery patients undergoing aggressive blood conservation.

    Main Methods:

    • A randomized controlled trial involving 113 cardiac surgery patients.
    • Patients were assigned to either an autotransfusion group (54) or a control group (59).

  • All patients received intraoperative and postoperative hemodilution.

    • Main Results:

    • The clinical safety of mediastinal autotransfusion was confirmed, with no septic, hematological, pulmonary, renal, or hepatic complications observed.
    • The technique did not demonstrate a significant reduction in the use of banked blood compared to the control group.

    Conclusions:

    • Autotransfusion of shed mediastinal blood is clinically safe following cardiac operations.
    • In settings with aggressive blood conservation, this technique may not offer additional benefits in reducing banked blood requirements.
