间歇充气加压泵及序贯加压袜对食管癌术后患者下肢深静脉血流动力学的影响

Effects of intermittent pneumatic compression and graded compression elastic stocking on lower limb venous hemodynamics of patients with postoperative esophageal cancer

摘要:

目的：探讨间歇充气加压泵（intermittent pneumatic compression，IPC）及序贯加压袜（graded compression elastic stocking，GCS）对食管癌术后患者下肢深静脉血流动力学的影响。方法：选取我科择期食管癌术后的患者45名，随机分为对照组和2个干预组，对照组采用传统护理方法，干预组采用GCS、IPC ２种方法，比较3组在股静脉血流峰值、血流平均速度及血流量指标值的差异。结果：GCS 组及IPC组的股静脉血流动力学指标值均高于对照组（血流峰速度、平均血流速度、血流量GCS组vs. 对照组P值分别为0.023、0.032、0.045；IPC组vs. 对照组P值分别为0.000、0.000、0.000）；IPC 组股静脉血流动力学指标值显著高于GCS 组（血流峰速度、平均血流速度、血流量IPC 组vs. GCS组P值分别为0.014、0.025、0.037）。结论：间歇充气加压泵与序贯加压袜均能加速下肢静脉血液回流，改善血流量，IPC法优于GCS法。

Abstract:

Objective：To discuss the effects of intermittent pneumatic compression（IPC） and graded compression elastic stocking（GCS） on lower limb venous hemodynamics of patients with postoperative esophageal cancer. Methods：Totally 45 patients with esophageal cancer after thoracotomy were chosen as subjects and were randomly divided into one control group and two intervention groups（GCS and IPC groups. Traditional nursing care was provided for patients in control group while IPC and GCS were carried out for patients in intervention groups. Hemodynamics parameters of the femoral vein including peak venous velocity，average venous velocity and unit time blood flow were compared among the three groups. Results：Hemodynamics indexes（including peak venous velocity，average ve－nous velocity and unit time blood flow） were higher in intervention groups than in control group（GCS group vs. control group：P=0.023，0.032，0.045；IPC group vs. control group：P=0.000，0.000，0.000）.Hemodynamics parameters of IPC group was higher than those in GCS group（P=0.014，0.025，0.037）. Conclusions：Both the GCS and IPC can accelerate venous velocity and improve blood flow and IPC is superior to GCS.
