Perioperative blood transfusions in orthopaedic surgery

Area of Science:

• Orthopaedic Surgery
• Transfusion Medicine
• Patient Blood Management

Background:

• Blood transfusions are common after orthopaedic surgery, representing 10% of all transfusions.
• Transfusion practices vary significantly between institutions and surgeons.
• Systemic complications associated with blood transfusions include allergic reactions, infections, and organ injury.

Purpose of the Study:

• To evaluate the efficacy of tranexamic acid in reducing blood loss and transfusion risk in total joint arthroplasty.
• To assess the appropriateness of transfusion triggers, specifically a hemoglobin level of >8 g/dL, in orthopaedic patients.

Main Methods:

• Review of current clinical evidence on blood management strategies in orthopaedic surgery.
• Analysis of studies supporting tranexamic acid use for reducing blood loss.
• Evaluation of evidence for restrictive hemoglobin transfusion thresholds (>8 g/dL).

Main Results:

• Tranexamic acid is a cost-effective tool for managing blood loss and reducing transfusion needs post-arthroplasty.
• Clinical evidence does not support transfusions for hemoglobin levels >8 g/dL without symptoms.
• Restrictive transfusion triggers are supported, even in patients with cardiovascular disease.

Conclusions:

• Optimizing blood management in orthopaedic surgery can decrease transfusion rates and associated risks.
• Tranexamic acid and evidence-based transfusion triggers are crucial for improving patient outcomes.
• Adopting standardized, evidence-based transfusion protocols enhances patient safety and resource utilization.
