NCT02345642

Brief Summary

We are comparing two pneumatic compression devices, VenaFlow (stationary) and MCS (portable) in both the supine an standing position. We will start supine and will take 3 baseline measurements of venous velocity and then apply a device and take 3 measurements of the increase in peak venous velocity. We will repeat this with the second device. We will then have the subject stand and repeat the above with each device. We will randomize the order of the devices in the supine and standing position. This study will involve 10 healthy subjects of various ages and 10 total hip replacements (THR) patients.

Outcome Measures

Primary Outcomes (1)

  • Peak Venous Velocity

    Ultrasound of the venous system just below the saphenofemoral junction to assess the venous velocity will be taken before and after application the VenaFlow and the ActiveCare+S.F.T pneumatic compression devices. Change from Baseline in Peak Venous Velocity 30 minutes after Device is applied is recorded.

    Change from Baseline in Peak Venous Velocity 30 minutes after Device is Applied

Study Arms (2)

10 Healthy Patients without THA

ACTIVE COMPARATOR

The 10 test subjects of this study arm will be healthy volunteers of various ages that are willing to have the efficacy of pneumatic compression tested on them.

10 Patients with THA on Post-Op Day 2

EXPERIMENTAL

The 10 test subjects of this study arm will be primary THR patients of Dr. Westrich that have undergone uncomplicated THR surgery in which they are allowed to be full weight bearing by or before post-op day 2.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Phase one: 10 healthy test subjects will be included of various ages. They will have each pneumatic compression device applied in the supine and then standing positions.
  • Phase two: 10 patients following THR on postoperative day #2 will be included. These patients will agree to participate in the study and have to be able to stand for approximately 10 minutes.

You may not qualify if:

  • Patients with lymphedema
  • Patients with peripheral vascular disease (chronic venous insufficiency)
  • Patients who do not wish to participate
