NCT03584100

Brief Summary

The purpose of the proposed study is to evaluate the acute impact of swelling caused by low-pressure tourniquet use in the setting of ipsilateral prior axillary lymph node dissection and the change in swelling reduction following tourniquet use in three limb postures versus healthy volunteers.

Outcome Measures

Primary Outcomes (1)

  • Change in Hand Volume Following Tourniquet Use

    Hand volume, as an indicator of limb edema / fluid accumulation, was determined with an aqueous volumeter at rest and for the sling and elevated arm positions 30 minutes after an arm tourniquet was placed. Measurements were taken for the affected arm \[ie, after axillary lymph node dissection (ALND)\], and the same patient's contralateral arm (control, ie, "other arm"). The mean values for each arm (affected vs control) of the participant group, before (baseline) and 30 minutes after placement of the pneumatic tourniquet were obtained. The difference represents the effect of tourniquet placement. The outcome is reported as the overall mean difference in hand volume from baseline to 30 minutes after tourniquet placement for the ALND arm (affected arm) and the contralateral arm (control arm), with standard deviation. 12 patients only.

    30 minutes after tourniquet use

Secondary Outcomes (1)

  • Difference in Hand Volume Following Tourniquet Use, Between ALND and Control Limbs

    30 minutes

Study Arms (2)

Patients with prior axillary lymph node dissection

EXPERIMENTAL

Participants raise their arm for 15 minutes, then wear a tourniquet 8000 inflated for 25 minutes. Hand volume is measured by aqueous volumeter at baseline, after use of the tourniquet and every 5 minutes for 30 minutes, while the arm is placed at a raised on head position, shoulder-level brace position, or at waist in a sling position.

Device: Tourniquet 8000

Healthy Volunteers

ACTIVE COMPARATOR

Participants raise their arm for 15 minutes, then wear a tourniquet 8000 inflated for 25 minutes. Hand volume is measured by aqueous volumeter at baseline, after use of the tourniquet and every 5 minutes for 30 minutes, while the arm is placed at a raised on head position, shoulder-level brace position, or at waist in a sling position.

Device: Tourniquet 8000

Interventions

Pneumatic tourniquet with appropriate upper extremity cuff, pressure sensing, and ability to set device at 40 mmHg of pressure

Also known as: Pneumatic tourniquet
Healthy VolunteersPatients with prior axillary lymph node dissection
