To evaluate the effectiveness of postoperative autologous blood transfusion on reducing the need for allogenic transfusion during recovery from total knee arthroplasty until hospital discharge, and to determine whether effectiveness is related to preoperative hemoglobin level.
Retrospective study of patients undergoing surgery at Hospital Jerez de la Frontera, Spain, in 2003, assessing the association between postoperative autologous blood transfusion, preoperative hemoglobin, and allogenic transfusion requirements.
A total of 107 patients were studied. Eighty-three received autologous blood transfusions after surgery and 15 (14.02%) required allogenic transfusion. The rate of allogenic transfusion was higher in association with hemoglobin levels exceeding 13 g x dL(-1) (P=0.003) and it was lower in patients who received autologous blood transfusions (P=0.046). In patients who received autologous transfusion, preoperative hemoglobin level and risk of allogenic transfusion were unrelated. When autologous transfusion was not given, allogenic transfusion risk was higher when hemoglobin concentration was less than 13 g x dL(-1) (P=0.0008). Autologous transfusion had a significant effect when hemoglobin level was less than 13 g x dL(-1) (P=0.002) but did not affect the rate of transfusion when hemoglobin was 13 g x dL(-1) or more.
Autologous blood transfusion is effective for reducing the need for allogenic transfusion after knee replacement surgery, particulary when a patient's hemoglobin level is less than 13 g x dL(-1).
评估全膝关节置换术后自体输血在减少直至出院康复期间异体输血需求方面的有效性，并确定有效性是否与术前血红蛋白水平相关。
对2003年在西班牙赫雷斯德拉弗龙特拉医院接受手术的患者进行回顾性研究，评估术后自体输血、术前血红蛋白与异体输血需求之间的关联。
共研究了107例患者。83例术后接受了自体输血，15例（14.02%）需要异体输血。血红蛋白水平超过13 g×dL⁻¹时异体输血率较高（P = 0.003），接受自体输血的患者异体输血率较低（P = 0.046）。在接受自体输血的患者中，术前血红蛋白水平与异体输血风险无关。未进行自体输血时，血红蛋白浓度低于13 g×dL⁻¹时异体输血风险较高（P = 0.0008）。当血红蛋白水平低于13 g×dL⁻¹时，自体输血有显著效果（P = 0.002），但血红蛋白为13 g×dL⁻¹或更高时不影响输血率。
自体输血对减少膝关节置换术后异体输血需求有效，尤其是当患者血红蛋白水平低于13 g×dL⁻¹时。
