Summary
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.
