In a consecutive series of 536 unilateral primary total hip arthroplasties (THAs) and 598 unilateral primary total knee arthroplasties (TKAs), the use of a post-operative drain was associated with $538 additional cost per THA, and $455 for TKA. The use of a drain increased hospital length of stay (LOS) for THA, but not for TKA. In both groups, the use of a drain increased estimated blood loss (EBL) and increased the amount of allogeneic blood transfused. Over the 10-week period, drain use was associated with a total cost of $432,972 for our institution. Data from this study would favor a selective approach to the use of drains in primary joint arthroplasties.
在连续的536例单侧初次全髋关节置换术（THA）和598例单侧初次全膝关节置换术（TKA）中，术后放置引流管使每例THA额外花费538美元，每例TKA额外花费455美元。放置引流管增加了THA的住院时间，但未增加TKA的住院时间。在两组中，放置引流管均增加了估计失血量（EBL）并增加了异体输血的量。在10周的时间里，放置引流管给我们机构带来的总成本为432,972美元。这项研究的数据支持在初次关节置换术中选择性使用引流管的方法。
