Postoperative wound drainage was aspirated, collected, and transfused in 197 patients undergoing unilateral or bilateral cementless knee arthroplasty using the Solcotrans or the Constavac Blood Conservation blood-retrieval devices. Operative technique, method of hemostasis, and postoperative management were identical in all patients. Drainage-tube suction pressure was minimized, and the duration of drainage collection was less than 8 hours in all patients. In the 153 patients who underwent unilateral total knee arthroplasty (TKA), the amount of blood retrieved and transfused averaged 829 cm3 (59% of total blood lost). For the 44 patients who underwent bilateral procedures, 1,131 cm3 of blood was salvaged (56% of total blood lost). Transfused banked blood averaged 1.7 units (25% homologous) in unilateral cases, while bilateral procedures required 3.0 units (35% homologous). Complications (4%) included wound hematomata in five patients and deep venous thrombosis in two. Transient chills, fever, or tachycardia were seen in four patients at the time of transfusion. Transfusion requirements of banked blood appeared to be significantly reduced, especially in simultaneous bilateral knee arthroplasty, when compared to previous experience in patients who did not undergo postoperative blood retrieval.
在197例接受单侧或双侧非骨水泥型膝关节置换术的患者中，使用Solcotrans或Constavac血液回收装置对术后伤口引流液进行抽吸、收集并回输。所有患者的手术技术、止血方法及术后处理均相同。所有患者均将引流管吸引压力降至最低，引流液收集时间均少于8小时。在153例行单侧全膝关节置换术（TKA）的患者中，回收并回输的平均血量为829立方厘米（占总失血量的59%）。在44例行双侧手术的患者中，回收了1131立方厘米的血液（占总失血量的56%）。单侧手术中，平均回输库存血1.7单位（25%为同源血），而双侧手术则需要3.0单位（35%为同源血）。并发症发生率为4%，包括5例伤口血肿和2例深静脉血栓形成。4例患者在输血时出现短暂寒战、发热或心动过速。与既往未进行术后血液回收的患者相比，库存血的输血需求量似乎显著减少，尤其是在同期双侧膝关节置换术中。
