The purpose of this study was to evaluate the benefits of suction drainage following primary total joint arthroplasty. We reviewed primary total hip and knee replacements separately and together in 126 consecutive patients. There were 63 patients each in the drainage and no drainage groups. Sex distribution and anticoagulant use were similar in the two groups. All patients underwent the same operative technique and method of closure. The mean postoperative fall in haemoglobin was 3.2 and 3.3 gm/dl in the drainage and no drainage groups respectively. There was no statistically significant difference between the two groups with regard to blood transfusion requirements, rehabilitation time, postoperative complications such as hypotension and wound infections (p>0.05). The average rehabilitation time in both groups was 8-9 days. The routine use of a suction drain is unnecessary after an uncomplicated total joint arthroplasty.
本研究的目的是评估初次全关节置换术后负压引流的益处。我们对126例连续患者分别及共同回顾了初次全髋关节和膝关节置换情况。引流组和非引流组各有63例患者。两组的性别分布和抗凝剂使用情况相似。所有患者均采用相同的手术技术和闭合方法。引流组和非引流组术后血红蛋白平均下降分别为3.2克/分升和3.3克/分升。两组在输血需求、康复时间、术后并发症如低血压和伤口感染方面无统计学显著差异（p>0.05）。两组的平均康复时间均为8 - 9天。单纯性全关节置换术后常规使用负压引流是不必要的。
