Blood conservation in major orthopedic surgery

Area of Science:

• Transfusion Medicine
• Surgical Blood Management
• Orthopedic Surgery

Background:

• Allogeneic blood transfusions carry risks, including disease transmission and immune reactions.
• Autologous blood strategies aim to reduce reliance on donor blood in surgical settings.
• Intraoperative autotransfusion and preoperative autologous donation are key components of blood conservation.

Purpose of the Study:

• To evaluate the safety and efficacy of intraoperative autotransfusion over an eight-year period.
• To assess the effectiveness of a combined preoperative and intraoperative autologous blood program.
• To determine the potential of autologous blood strategies in replacing allogeneic blood transfusions.

Main Methods:

• Retrospective analysis of 1922 surgical cases involving intraoperative autotransfusion.
• Categorization of procedures included primary hip arthroplasty, revision hip arthroplasty, spinal procedures, and vascular cases.
• Evaluation of a four-year experience with a preoperative autologous blood program, including predonation.

Main Results:

• No complications related to intraoperative autotransfusion were reported in any of the 1922 cases.
• Red cell salvage via intraoperative autotransfusion achieved approximately 58% effectiveness in reducing blood loss.
• A combined autologous donation and intraoperative autotransfusion program met the blood needs for 72% of revision hip arthroplasties and 81% of spinal instrumentations.

Conclusions:

• Intraoperative autotransfusion is a safe and effective method for reducing intraoperative blood loss.
• Combined preoperative autologous blood donation and intraoperative autotransfusion offer a viable alternative to allogeneic blood replacement.
• These autologous blood strategies can significantly minimize or eliminate the need for donor blood, thereby reducing transfusion-related risks.
