Blood management in total joint arthroplasty

Area of Science:

• Orthopaedic Surgery
• Perioperative Care
• Transfusion Medicine

Background:

• Avoiding allogeneic blood transfusion is a key goal in orthopedic perioperative care.
• Minimizing surgical blood loss can be achieved through regional hypotensive anesthesia, meticulous surgical technique, and effective coagulation.
• Coagulation challenges exist in spinal and arthroplasty procedures due to large, vascular cancellous surfaces.

Purpose of the Study:

• To outline comprehensive blood management strategies for orthopedic patients.
• To emphasize the importance of reducing allogeneic transfusions in joint arthroplasty.
• To highlight methods for minimizing perioperative blood loss and transfusion risks.

Main Methods:

• Implementing all available autologous blood salvage techniques: preoperative deposit, hemodilution, intraoperative salvage, and postoperative retrieval.
• Utilizing perioperative recombinant erythropoietin to stimulate red blood cell production.
• Employing regional hypotensive anesthesia and careful surgical techniques to minimize bleeding.

Main Results:

• Comprehensive blood management significantly reduces the need for allogeneic transfusions.
• Autologous blood salvage methods are effective in preserving patient blood volume.
• Recombinant erythropoietin aids in increasing red cell mass preoperatively.

Conclusions:

• Integrated blood management protocols are essential for safe orthopedic surgery, particularly joint arthroplasty.
• While screening has improved, allogeneic transfusions still carry risks of adverse reactions and viral transmission.
• Proactive strategies for blood conservation are vital for patient safety and optimal outcomes in orthopedics.
