Simultaneous bilateral total knee arthroplasty (TKA) is associated with excessive blood loss and morbidity arising from postoperative reduction in hemoglobin (Hb). The purpose of this prospective randomized study was to determine if drains have any effect on blood loss, postoperative reduction in Hb levels and transfusion rates compared to no drainage in simultaneous bilateral TKAs.
Two hundred and thirty patients who underwent simultaneous bilateral TKA by a single surgeon were randomly allotted to drain or no-drain group (n=115 in each group). Postoperative Hb level, blood loss volume and transfusion rate were compared between the two groups.
The mean postoperative Hb level (p=0.38), blood loss volume (p=0.33) and transfusion rate (p=0.52) in the drain group were not significantly different compared to the no-drain group. No statistical difference was found in terms of complications, readmissions and mortality rates between the two groups.
No significant difference was observed in the two groups with respect to blood loss and blood transfusion. Non-drainage does not offer an advantage over drainage with respect to conserving blood in simultaneous bilateral TKA.
同期双侧全膝关节置换术（TKA）与因术后血红蛋白（Hb）降低导致的失血过多及发病率相关。这项前瞻性随机研究的目的是确定与同期双侧TKA不放置引流管相比，放置引流管对失血量、术后Hb水平降低及输血率是否有任何影响。
230例由同一外科医生进行同期双侧TKA的患者被随机分配至引流组或不引流组（每组n = 115）。比较两组术后Hb水平、失血量及输血率。
与不引流组相比，引流组术后平均Hb水平（p = 0.38）、失血量（p = 0.33）及输血率（p = 0.52）无显著差异。两组在并发症、再入院率及死亡率方面未发现统计学差异。
两组在失血量和输血方面未观察到显著差异。在同期双侧TKA中，不放置引流管在保存血液方面并不优于放置引流管。
