空气波压力治疗预防全膝关节置换后下肢深静脉血栓

背景：大量文献研究表明，空气波压力治疗在预防髋部大手术后下肢深静脉血栓形成中有重要作用。目的：探讨空气波压力治疗仪对预防全膝关节置换后下肢深静脉血栓的效果。方法：80例全膝关节置换患者随机数字表法均分为试验组和对照组，对照组行常规治疗与护理加个人行为功能锻炼，试验组在对照组基础上，置换后第2天采用空气波压力治疗仪治疗双下肢；比较两组患者患肢肿胀指数、凝血综合指数及发生下肢深静脉血栓的例数。结果与结论：治疗后2周，试验组肿胀指数、凝血综合指数及发生下肢深静脉血栓的例数明显减少，其效果明显优于对照组，差异有显著性意义（P〈0.05）。全膝关节置换后早期应用空气波压力治疗仪能有效缓解患肢肿胀，改善凝血综合指数，改善患者的血凝状态，预防人工全膝关节置换后的下肢深静脉血栓形成。

Air wave pressure therapy in prevention of deep vein thrombosis of the lower extremity after total knee arthroplasty

BACKGROUND：Numerous studies have shown that air wave pressure therapy plays an important role in prevention of deep venous thrombosis of lower limb after a major operation on the hip. OBJECTIVE：To explore the efficacy of air wave pressure therapy on deep vein thrombosis of the lower extremity in patients with total knee arthroplasty. METHODS：A total of 80 patients with total knee arthroplasty were randomly divided into experimental group and control group. Patients in the control group were treated only with conventional method to help the patient massage the lower extremity by the nurse and combined with active functional exercise;patients in the experimental group were treated with air wave pressure therapy at 2 days iostoperatively, and were also treated with conventional method to help the patient massage the lower extremity by the nurse and combined with active functional exercise. Swel ing index, coagulation index and the number of patients with deep venous thrombosis of the lower extremity were recorded in both groups.RESULTS AND CONCLUSION：At 2 weeks after treatment, swel ing index, coagulation index and the number of patients with deep venous thrombosis of the lower extremity were significantly reduced in the experimental group, and its effects were significantly better than those in the control group （P〈0.05）. Early use of air wave pressure therapy after total knee arthroplasty can al eviate limb swel ing effectively and have obvious advantages in improving coagulation index and blood coagulation condition and in preventing deep vein thrombosis of the lower extremity after total knee arthroplasty.
