Summary
Blood transfusion practices in knee replacement surgery are inconsistent due to a lack of guidelines. This audit found transfusions often lacked evidence, highlighting the need for standardized transfusion protocols in total knee arthroplasty.
Area of Science:
- Orthopedic Surgery
- Transfusion Medicine
- Healthcare Audit
Background:
- No universal guidelines exist for blood transfusion in primary, unilateral Total Knee Replacement Arthroplasty (TKA).
- Transfusion is linked to increased infection risk, fluid overload, and longer hospital stays.
- Concerns over inappropriate transfusion practices prompted a local audit.
Purpose of the Study:
- To audit local blood transfusion practices in primary, unilateral TKA.
- To assess compliance with existing evidence-based transfusion guidelines.
Main Methods:
- A 1-year retrospective survey of blood transfusion practices.
- Inclusion of all consecutive elective, primary, unilateral TKA operations.
Main Results:
- 34% of 169 TKA patients received transfusions, 60% intra-operatively.
- No pre-operative hemoglobin threshold predicted transfusion; 74% of cross-matched blood was unused.
- Negligible blood loss and minimal cardiovascular instability observed in transfused patients.
Conclusions:
- Lack of guidelines results in inconsistent and often unsupported transfusion practices in TKA.
- Suggested transfusion guidelines are proposed based on indirect scientific evidence.
- Further research, including randomized controlled trials, is needed to establish definitive guidelines.
