The use of re-infusion drains on 99 consecutive patients undergoing total knee arthroplasty surgery at a large hospital was analysed. As a control group the records of 99 patients treated without re-infusion were analysed retrospectively. The primary aim was to ascertain the cost effectiveness of the drains. Secondary aims were to assess safety of the drains, whether or not they reduced the need for allogeneic blood transfusion and whether they decreased the length of stay in hospital. The direct cost of consumables increased for the evaluation period. There was a smaller proportion of allogeneic blood transfusion (27% vs 38%) and a smaller mean number of units transfused (0.92 vs 0.54) in the re-infusion group compared to the control group. Patients benefited directly in that the mean length of stay was also significantly shorter in the re-infusion group. We anticipate more direct cost saving with experience and best practice and conclude that the use of re-infusion drains is a cost effective blood saving method in total knee joint arthroplasty.
对一家大型医院连续99例行全膝关节置换手术患者使用回输引流管的情况进行了分析。作为对照组，回顾性分析了99例未使用回输引流管治疗患者的记录。主要目的是确定引流管的成本效益。次要目的是评估引流管的安全性、是否减少了异体输血需求以及是否缩短了住院时间。在评估期间，耗材的直接成本有所增加。与对照组相比，回输组的异体输血比例较小（27%对38%），平均输血量也较少（0.92对0.54）。回输组患者直接受益，因为其平均住院时间也明显更短。我们预计随着经验积累和最佳实践的应用，会节省更多直接成本，并得出结论，在全膝关节置换术中使用回输引流管是一种具有成本效益的节省血液的方法。
