新型防治足下垂气压牵引带用于下肢手术后 血栓护理防治效果的分析

Analysis of the Preventive Effect of a Novel Pneumatic Traction Device for Foot Drop on Deep Vein Thrombosis after Lower Limb Surgery

摘要: 目的：观察新型防治足下垂气压牵引带联合标准方案预防骨科下肢手术后深静脉血栓(DVT)的临床效果。方法：选取下肢骨折术后患者70例，随机分为两组，各35例。对照组采用标准药物预防 + 常规护理指导，实验组在标准药物预防 + 常规护理指导基础上加用新型防治足下垂气压牵引带。以下肢血管多普勒超声确诊DVT发生率为主要终点，次要终点包括肺栓塞(PE)发生率、AOFAS踝关节功能评分、VAS疼痛评分、患者舒适度及满意度。结果：实验组DVT发生率显著低于对照组，AOFAS评分、舒适度及满意度显著高于对照组，VAS疼痛评分显著低于对照组(P < 0.05)。结论：骨科下肢手术后，在标准药物预防联合常规护理指导基础上应用新型防治足下垂气压牵引带，可显著降低DVT发生率，改善踝关节功能，提升患者康复质量与满意度。

Abstract: Objective: To observe the clinical effect of a novel pneumatic traction device for foot drop combined with a standard protocol in preventing deep vein thrombosis (DVT) after orthopedic lower limb surgery. Methods: A total of 70 patients after lower limb fracture surgery were randomly divided into two groups (35 cases each). The control group received standard pharmacological prophylaxis + routine nursing care, while the experimental group received the same standard prophylaxis and routine care plus the novel pneumatic traction device for foot drop. The primary endpoint was the incidence of DVT confirmed by lower limb vascular Doppler ultrasound. Secondary endpoints included the incidence of pulmonary embolism (PE), AOFAS ankle-hindfoot function score, VAS pain score, patient comfort, and satisfaction. Results: The incidence of DVT in the experimental group was significantly lower than that in the control group. The AOFAS score, comfort level, and satisfaction were significantly higher, and the VAS pain score was significantly lower in the experimental group compared with the control group (P < 0.05). Conclusion: Adding the novel pneumatic traction device for foot drop to the standard pharmacological prophylaxis and routine nursing care after orthopedic lower limb surgery can significantly reduce the incidence of DVT, improve ankle joint function, and enhance rehabilitation quality and patient satisfaction.
