摘要:
[背景] 局部应用氨甲环酸(TXA)降低全膝关节置换术(TKA)后失血已获得临床认可，但TKA术后TXA关节腔内注射联合引流管夹闭时间的系统研究很少。[目的] 研究TKA术后TXA关节腔内注射不同引流管夹闭时间对术后失血量、输血量及并发症等的影响，以选择TKA术后TXA关节腔内注射夹闭引流管的最佳时间。[方法] 对2015年1月至2016年3月入住青岛大学附属医院的152例膝骨关节炎行首次单侧TKA的患者进行回顾分析，152例患者于缝合关节囊后均经注射器向关节腔内注射TXA注射液(50 ml，40 mg/ml)并夹闭引流管，释放止血带前绷带加压包扎膝关节。152例患者根据引流管的夹闭时间随机分为4组(夹闭1 h组、夹闭2 h组、夹闭3 h组、夹闭4 h组)，各组38例。计算术中出血量、总失血量、术后可见失血量及隐性失血量，统计术后输血、患肢皮下瘀斑、患肢膝关节肿胀及患肢肌间静脉血栓人数，评估术后6月患肢膝关节HSS评分。[结果] 在总失血量、术后可见失血量、隐性失血量及术后输血率方面，夹闭3 h组、夹闭4 h组明显低于夹闭1 h组、夹闭2 h组，且夹闭2 h组明显低于夹闭1 h组；夹闭4 h组术后患肢皮下瘀斑、患肢膝关节肿胀的发生率显著增加；术后6月膝关节HSS评分，4组患者比较差别无统计学意义。[结论] TKA术后TXA关节腔内注射引流管夹闭3h是最佳选择。
[Background] Topical application of tranexamic acid in reducing blood loss after total knee arth-roplasty is clinically recognized. But systematic studies about intra-articular injection of tranex-amic acid of drainage tube clamping time after total knee arthroplasty are rarely. [Objective] To explore the effects of intra-articular injection of tranexamic acid with different drainage tube clamping time after total knee arthroplasty to postoperative blood loss, blood transfusion and complications. To select the optimal drainage tube clamping time about intra-articular injection of tranexamic acid after total knee arthroplasty. [Methods] Retrospective analysis of 152 patients with knee osteoarthritis admitted to the Affiliated Hospital of Qiingdao University from January 2015 to March 2016. 152 patients were performed primary total knee arthroplasty. Injection of TXA injection (50 ml, 40 mg/ml) into the articular cavity via syringe after suture of joint capsule and clamped drainage tube, then bandage compression knee joint, release tourniquet. 152 patients were randomly divided into 4 groups according to the duration of the closure of the drainage tube (clipping 1 h group, clamping 2 h group, clamping 3 h group, clamping 4 h group), each group included 38 patients. The amount of intraoperative blood loss, total blood loss, postoperative visible blood loss and hidden blood loss was calculated. Postoperative blood transfusion, limb subcutaneous ecchymosis, knee swelling and limb muscular venous thrombosis number were counted. Knee Hospital for Special Surgery score was evaluated at 6 months after replacement. [Results] In terms of total blood loss, postoperative visible blood loss and hidden blood loss, postoperative blood transfusion rate, clamping 3 h group, clamping 4 h group were significantly lower than that of clipping 1 h group, clamping 2 h group, and clamping 2 h group was significantly lower than that of clipping 1 h group. Postoperative limb subcutaneous ecchymosis, knee swelling incidence of clamping 4 h group increased significantly. There was no significant difference in the HSS score between the 4 groups at 6 months postoperatively. [Conclusion] Clamping drainage tube for 3 h is the best choice about intra-articular injection of tranexamic acid after total knee arthroplasty.
