To assess the efficacy of unilateral use of a blood reinfusion device in one-stage bilateral total knee arthroplasty (TKA).
We carried out a retrospective cohort study on 100 patients having one-stage bilateral TKA. In 50 of these patients (study group), a blood reinfusion device was applied on one knee and a standard suction drain on the other, and they were compared with 50 matched controls who received bilateral suction drains (control group). The hemoglobin (Hb) level, the hematocrit (Hct) and the platelet count were checked preoperatively, immediately postoperatively, and the third and seventh days postoperatively. The total drain output and the amount of allogeneic blood transfusion were also compared.
There were no significant differences in the total drain output and required amount of allogeneic blood transfusions between groups (p>0.05). However, the study group had significantly lower Hb and Hct values by the first day postoperatively and significantly lower platelet count values by the third day postoperatively than the control group (p<0.05).
Compared with use of bilateral suction drains, unilateral use of reinfusion device was not advantageous in reducing allogeneic transfusion in one-stage bilateral TKA.
评估在一期双侧全膝关节置换术（TKA）中单侧使用血液回输装置的疗效。
我们对100例行一期双侧TKA的患者进行了一项回顾性队列研究。在其中50例患者（研究组）中，一侧膝关节应用血液回输装置，另一侧应用标准吸引引流管，将其与50例接受双侧吸引引流管的匹配对照患者（对照组）进行比较。在术前、术后即刻、术后第三天和第七天检查血红蛋白（Hb）水平、血细胞比容（Hct）和血小板计数。还比较了总引流量和异体输血的量。
两组之间的总引流量和异体输血所需量无显著差异（p>0.05）。然而，研究组术后第一天的Hb和Hct值明显低于对照组，术后第三天的血小板计数值也明显低于对照组（p<0.05）。
与双侧使用吸引引流管相比，在一期双侧TKA中单侧使用回输装置在减少异体输血方面并无优势。
