利湿逐瘀汤对膝关节置换术后患者下肢深静脉血栓的预防作用分析

Analysis on Preventive Effect of Lishi Zhuyu Decoction on Lower Extremity Deep Venous Thrombosis of Patients after Knee Replacement

目的分析利湿逐瘀汤对膝关节置换术后患者下肢深静脉血栓的预防作用。方法选取我院行膝关节置换术的患者80例,随机分为实验组和对照组各40例。对照组采取指南规范的预防治疗措施,实验组在对照组基础上采用利湿逐瘀汤治疗。比较两组患者的下肢周径差和下肢深静脉血栓发生率。结果术后14 d,两组患者的大腿周径差、小腿周径差均小于术后1 d,且实验组的大腿周径差、小腿周径差均小于对照组(P均<0.05);两组的下肢深静脉血栓发生率比较差异无统计学意义(P>0.05)。结论膝关节置换术后应用利湿逐瘀汤可改善患者的血液高凝状态,对下肢深静脉血栓形成具有预防作用。

Objective To analyze the preventive effect of Lishi Zhuyu decoction on lower extremity deep venous thrombosis of patients after knee replacement. Methods 80 cases of patients with knee replacement in our hospital were selected and randomly divided into experimental group and control group, with 40 cases in each group. The control group was given preventive treatment measures of guideline specification, and the experimental group was given Lishi Zhuyu decoction on the basis of control group. The circumference difference of lower limbs, and the incidence of lower extremity deep venous thrombosis were compared between the two groups. Results 14 d after operation, the thigh circumference difference and calf circumference difference of the two groups were less than those at 1 d after operation,and the thigh circumference difference and calf circumference difference of the experimental group were less than those of the control group(all P <0.05). No statistical difference was found in the incidence of lower extremity deep venous thrombosis between the two groups(P>0.05). Conclusions Lishi Zhuyu decoction after knee replacement can improve the blood hypercoagulability of patients and prevent the formation of lower extremity deep venous thrombosis.
