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

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.
