A clinical experience with intraoperative autotransfusion.

Area of Science:

• Surgical Innovation
• Transfusion Medicine
• Patient Safety

Background:

• Significant blood loss is a common complication in major surgeries.
• Autologous blood transfusion can mitigate risks associated with homologous blood.
• Intraoperative autotransfusion offers a method to reinfuse a patient's own blood during surgery.

Purpose of the Study:

• To evaluate the safety and efficacy of intraoperative autotransfusion using a disposable unit.
• To assess the feasibility of this technique in a hospital setting.
• To determine the outcomes of patients undergoing intraoperative autotransfusion.

Main Methods:

• A disposable unit for intraoperative autotransfusion was utilized in 53 patients.
• Indications included anticipated blood loss of ≥1,000 ml.
• Contraindications were colon injury or localized infection.

Main Results:

• Over 325 units of blood were salvaged and reinfused.
• One death occurred due to air embolism; 20 other deaths were related to severe injuries.
• Transient abnormalities in clotting factors and hemoglobin were noted, but without clinical defects or renal issues.

Conclusions:

• Intraoperative autotransfusion is a safe and practical procedure when properly employed.
• The technique is technically feasible for managing substantial intraoperative blood loss.
• Postoperative blood cultures were negative, indicating no infectious complications from the procedure.
