The relationship between patient hematocrit level, red blood cell volume lost, and blood units transfused is important in determining conservation strategies in patients undergoing total knee replacement surgery. In a series of 30 such patients, 3 (10%) received allogeneic blood, despite preoperative autologous blood donation in 28 patients. There was no evidence that the degree of anemia affected rate or volume of postoperative wound blood drainage. The wound drainage volume that could have been salvaged and reinfused in bilateral procedures was substantial. A combination of one or more conservation techniques along with conservative transfusion practice is necessary to achieve minimal allogeneic blood exposure.
患者血细胞比容水平、红细胞丢失量与输注的血液单位数之间的关系，对于确定全膝关节置换手术患者的血液保护策略至关重要。在一系列30例此类患者中，尽管28例患者术前进行了自体血捐献，但仍有3例（10%）接受了异体血。没有证据表明贫血程度会影响术后伤口引流的速度或量。在双侧手术中，本可回收并回输的伤口引流量相当可观。为了使异体血暴露降至最低，需要将一种或多种血液保护技术与保守的输血实践相结合。
