Intra- and postoperative autotransfusion is a safe and effective blood conservation method for major surgeries. This technique, utilizing advanced cell savers, removes harmful substances from red blood cells before reinfusion.

Area of Science:

  • Medical Science
  • Surgical Techniques
  • Hematology

Context:

  • Intra- and postoperative autotransfusion is a well-established clinical practice.
  • It is often combined with other blood-saving techniques like preoperative blood deposit, plasmapheresis, and normovolemic hemodilution.
  • Recent advancements in autotransfusion devices have increased their acceptance among medical professionals.

Purpose:

  • To describe the mechanism and benefits of intra- and postoperative autotransfusion.
  • To highlight the importance of washing red blood cells during autotransfusion.
  • To discuss the safety and contraindications of this blood conservation technique.

Summary:

  • Autotransfusion involves separating and washing red blood cells in saline to remove plasma-free hemoglobin, potassium, enzymes, triglycerides, anticoagulants, activated clotting factors, and debris.

  • Modern microelectronic autotransfusion devices (e.g., Haemonetics Cell Saver, Dideco Autotrans) are highly accepted by anesthesiologists and surgeons.
  • The procedure is considered very safe for patients undergoing major operations when contraindications like bacterial contamination and cancer surgery are considered.

    • Impact:

    • Enhances patient safety during major surgeries by conserving blood.
    • Reduces the need for allogeneic blood transfusions.
    • Improves the quality of reinfused red blood cells by removing harmful substances.
