A prospective study of 48 patients (96 hips) who had undergone primary simultaneous bilateral total hip arthroplasty was conducted to assess the effect of postoperative suction drainage on wound healing and infection. A suction drain was placed by randomization of the drained versus undrained side. The same surgical technique was used in all total hip arthroplasty wounds. Statistical analysis of the results showed significant differences with respect to drainage from the wound, soaked dressings requiring reinforcements, ecchymosis, and erythema about the wound in the group without drainage. There was no specific correlation between the incidence of wound complications and infection after total hip arthroplasty and the use or nonuse of closed-suction drainage. The hip score and range of motion of the hip were unaffected by the use or nonuse of the drains. The cost of 1 set of hemovac drains is $135 and the cost for 4-5 dressings and bed sheet changes is about $50. Although the hemovac is more expensive, the authors recommend the routine use of suction drains for wounds after primary total hip arthroplasty to reduce drainage, soaked dressings requiring reinforcement, ecchymosis and erythema around the wound, and psychological impact on the patient's fear of bleeding.
对48例（96髋）接受初次同期双侧全髋关节置换术的患者进行了一项前瞻性研究，以评估术后负压引流对伤口愈合和感染的影响。通过随机分配引流侧和未引流侧来放置负压引流管。所有全髋关节置换术伤口均采用相同的手术技术。结果的统计分析显示，在未进行引流的组中，伤口引流、需要更换的浸湿敷料、瘀斑及伤口周围红斑方面存在显著差异。全髋关节置换术后伤口并发症和感染的发生率与是否使用闭式负压引流之间没有特定关联。引流管的使用与否对髋关节评分及髋关节活动范围没有影响。一套负压引流装置的成本为135美元，4 - 5次更换敷料和床单的成本约为50美元。尽管负压引流装置成本更高，但作者建议在初次全髋关节置换术后常规对伤口使用负压引流，以减少引流、需要更换的浸湿敷料、伤口周围的瘀斑和红斑，以及患者对出血恐惧的心理影响。
