Summary
Transfusion practices for hip and knee arthroplasty are generally acceptable. For autologous transfusion programs, three units suffice for most hip surgeries, while two units meet most knee surgery needs.
Area of Science:
- Orthopaedic Surgery
- Transfusion Medicine
- Patient Blood Management
Background:
- Hip and knee arthroplasty are common procedures with significant blood loss potential.
- Optimizing transfusion strategies is crucial for patient safety and resource management.
Purpose of the Study:
- To evaluate transfusion practices in hip and knee arthroplasty.
- To determine transfusion needs for autologous transfusion programs.
Main Methods:
- Retrospective study of 12 months of cross-match and transfusion data.
- Analysis of transfusion requirements for hip and knee arthroplasty patients.
Main Results:
- Over 75% of transfusions occurred peri-operatively.
- 89% of hip arthroplasty patients needed ≤3 units; 86% of knee arthroplasty patients needed ≤2 units.
- Transfusion index (Ti) for knee arthroplasty varied with preoperative hemoglobin, unlike hip arthroplasty.
Conclusions:
- Three units of blood are sufficient for 89% of hip arthroplasties in an autologous program.
- Two units suffice for 86% of knee arthroplasties.
- Preoperative autologous donation for knee arthroplasty in patients with Hb >13 g/dL may be unnecessary due to low transfusion index (0.6).
