We aim to determine whether the presence of a drain increases the actual blood transfusion rates in patients undergoing primary total knee arthroplasty (TKA). A retrospective review was performed on two consecutive groups of patients who underwent primary TKA: group 1 including 100 patients who underwent TKA and had one deep closed suction drain; group 2 including 100 patients who underwent TKA and had no drain. Blood transfusions were given post-operatively on the basis of clinical need without a pre-determined haemoglobin trigger factor. Group 1 drained a mean of 692 ml (range 150-1500) of blood in 48 h. The mean fall in haemoglobin at 48 h post-operatively was 3.26 g/dl in group 1 and 3.33 g/dl in group 2. Nine patients in group 1 and seven patients in group 2 required a blood transfusion; this was not statistically significant (P=0.79). Transfusion of primary TKA patients on the basis of clinical need can result in post-operative transfusion rates of 8%. The presence of a drain does not increase the transfusion rates of patients undergoing primary TKA.
我们旨在确定引流管的存在是否会增加初次全膝关节置换术（TKA）患者的实际输血率。对连续两组接受初次TKA的患者进行了回顾性研究：第1组包括100例行TKA且有一根深部闭合吸引引流管的患者；第2组包括100例行TKA但没有引流管的患者。术后根据临床需要进行输血，没有预先确定的血红蛋白触发因素。第1组在48小时内平均引流出692毫升（范围150 - 1500毫升）血液。术后48小时，第1组血红蛋白平均下降3.26克/分升，第2组为3.33克/分升。第1组有9例患者、第2组有7例患者需要输血；这在统计学上无显著差异（P = 0.79）。根据临床需要对初次TKA患者进行输血，术后输血率可达8%。引流管的存在并不会增加初次TKA患者的输血率。
