We studied the management of postoperative drainage after total knee replacement (TKR). 90 primary total knee joint arthroplasties were prospectively randomized into 3 groups: a) no drain, b) an autotransfusion system, c) a standard disposable closed suction drainage system. We monitored hemoglobin and hematocrit values, drainage volume and transfusions (homologous and autologous), range of knee motion, knee swelling and hospital stay. Parameters were recorded preoperatively, days 0-8 and 4 months postoperatively. No significant differences were seen between the groups in any of the parameters measured. The results show no benefit from using postoperative drainage systems in knee arthroplasties. Savings of SEK 400 (USD 55) per patient would have resulted if drains had not been used at all.
我们研究了全膝关节置换术（TKR）后术后引流的管理。90例初次全膝关节置换术患者被前瞻性随机分为3组：a）不置引流管，b）自体输血系统，c）标准一次性闭式吸引引流系统。我们监测了血红蛋白和血细胞比容值、引流量和输血情况（异体和自体）、膝关节活动范围、膝关节肿胀情况及住院时间。在术前、术后第0 - 8天和术后4个月记录各项参数。在测量的任何参数中，各组之间均未观察到显著差异。结果表明，在膝关节置换术中使用术后引流系统并无益处。如果根本不使用引流管，每位患者可节省400瑞典克朗（55美元）。
