Summary
Immediate transfusion of preoperatively donated autologous blood (PAB) after total knee arthroplasty (TKA) reduced nonsurgical complications. This approach is recommended, particularly for elderly patients, to improve outcomes and avoid transfusion risks.
Area of Science:
- Orthopedic Surgery
- Transfusion Medicine
- Patient Safety
Background:
- Increasing use of preoperatively donated autologous blood (PAB) to mitigate allogeneic transfusion risks.
- Controversy exists regarding transfusion criteria for autologous versus allogeneic red blood cells.
- Total knee arthroplasty (TKA) is associated with significant blood loss (average 1,400 mL).
Purpose of the Study:
- To prospectively compare immediate PAB transfusion versus a delayed transfusion strategy based on a 9.0 g/dL hemoglobin trigger point post-TKA.
- To evaluate the impact of transfusion timing on nonsurgical complications in TKA patients.
Main Methods:
- Prospective, randomized study comparing two PAB transfusion protocols after TKA.
- Group 1: Immediate PAB transfusion in the recovery room.
- Group 2: Delayed PAB transfusion triggered by hemoglobin < 9.0 g/dL.
Main Results:
- Patients receiving immediate PAB transfusions experienced significantly fewer nonsurgical complications (P < .002).
- Immediate transfusion strategy demonstrated a benefit in reducing adverse events.
Conclusions:
- Immediate postoperative PAB transfusion following TKA is recommended to reduce nonsurgical complications.
- This strategy is particularly beneficial for elderly patients due to their increased risk of complications.
- Optimizing PAB use can enhance patient safety in major orthopedic procedures.
