不同踝关节主动屈伸运动时间对全髋关节置换术后患者下肢静脉血液流速的影响

Effects of different exercise duration of ankle joint active flexion and extension exercise on lower limb venous blood flow velocity after total hip arthroplasty

目的探讨不同踝关节主动屈伸运动时间对全髋关节置换术后患者下肢静脉血液流速的影响。方法选择2018年1月-2020年1月医院骨科收治的行全髋关节置换术患者63例,给予足踝最大限度跖屈背伸交替活动,运动持续时间分别为1、2、3、4、5、10 s/次,对比患者在静息状态及不同持续时间下的下肢股静脉血管直径及血流峰值速度变化情况。结果足踝跖屈背伸运动持续2、3 s/次时患者下肢股静脉血管直径大于静息状态时下肢股静脉血管直径,差异有统计学意义(P<0.05);足踝跖屈背伸运动持续2、3s/次时患者下肢股静脉血流峰值速度均高于静息状态时下肢股静脉血流峰值速度,差异有统计学意义(P<0.05)。结论对全髋关节置换术后患者实施足踝最大限度跖屈背伸交替活动,运动持续时间2 s/次及3 s/次,可有效增大下肢股静脉血管直径,提高血流峰值速度。

Objective To explore the effect of different duration of ankle joint active flexion and extension exercise on the blood flow velocity of lower extremity vein in patients after total hip replacement.Methods From January 2018 to January 2020,63 patients with total hip replacement were selected.The patients were given 1,2,3,4,5,10 seconds per time of ankle joint active flexion and extension exercise,respectively.The changes of the diameter and peak velocity of the femoral vein blood flow of the lower extremity in resting state and different durations were compared.Results The diameter of the femoral vein of the lower extremity was larger than that of the resting state for 2 or 3 seconds per time,the difference was statistically significant(P<0.05);the peak velocity of the femoral vein blood flow of the lower extremity for 2 or 3 seconds per time was higher than that of the resting state,the difference was statistically significant(P<0.05).Conclusion The ankle joint active flexion and extension exercise for 2 and 3 seconds per time can effectively increase the diameter of femoral vein and the peak velocity of blood flow for patients after total hip replacement.
