Is prophylactic intraoperative transfusion needed in unilateral total knee arthroplasty? Comparison of hematologic data and postoperative transfusion rate between a prophylactic allogenic or autologous transfusion group with a no-transfusion group: A preliminary retrospective cohort study - 18/04/24
Highlights |
• | Prophylactic transfusion in total knee arthroplasty is not needed. |
• | Prophylactic transfusion (allogenic or autologous) does not reduce postoperative transfusion. |
• | Intra-articular tranexamic acid reduces postoperative transfusion. |
Abstract |
Objectives |
To determine whether prophylactic intra-operative allogenic or autologous transfusion could prevent postoperative anemia and additional transfusion comparing to the control group without receiving any prophylactic intervention in unilateral total knee arthroplasty.
Materials and methods |
This study included 711 patients who underwent unilateral TKA. They were divided into four groups: allogeneic transfusion group (group AL), autologous transfusion group (group AT), tranexamic acid group (group TA), and control group (group C). The primary outcome was rate of postoperative allogeneic blood transfusions. Secondary outcomes were postoperative hemoglobin and hematocrit levels, postoperative bleeding amount.
Results |
Groups AT and AL did not exhibit a significant reduction in postoperative allogenic blood transfusion rate compared to group C (28/108 vs. 20/108, p = 0.21 and 37/159 vs. 34/159, p = 0.78 respectively). However, group TA demonstrated a significantly lower rate of postoperative allogenic blood transfusions than group C (22/125 vs. 3/125, p = 0.0001). Postoperative hemoglobin and hematocrit levels were statistically higher in group TA than in group C. However, those levels in group AT and AL did not differ significantly from those of group C.
Conclusion |
Intra-operative prophylactic transfusions did not decrease postoperative anemia or additional postoperative transfusion compared to the control group in patients undergoing total knee arthroplasty. However, the group receiving tranexamic acid showed lower transfusion rate and higher levels of hemoglobin and hematocrit.
