NCT03746132

Brief Summary

The purpose of this clinical trial is to evaluate Transdermal Continuous Oxygen Therapy (TCOT) as an adjunct to surgical wound healing in subjects undergoing vascular surgery for lower extremity arterial occlusive disease. It is the intention of this study to administer oxygen using the TCOT approach to the surgical sites of subjects undergoing the surgery and to monitor the healing of the incision as well as infection rate. The hypothesis is that oxygen delivered transdermally to the surgical site in a continuous manner for up to 28 days will accelerate the healing process and reduce the infection rate compared to the Standard of Care.

Outcome Measures

Primary Outcomes (1)

  • surgical wound closure assessed using modified Bates-Jenson Wound Assessment Tool

    Change in wound area

    4 weeks

Secondary Outcomes (1)

  • Incidence of surgical site infection as determined by Szilagyi Tool

    90 days

Study Arms (2)

Transdermal Continuous Oxygen Therapy

ACTIVE COMPARATOR

Subjects who satisfy the inclusion/exclusion conditions will be randomly assigned to the Treatment arm which provides Transdermal Continuous Oxygen Treatment (TCOT) (as delivered by EPIFLO device), in addition to standard of care for the surgical wound

Device: EPIFLO

Control

NO INTERVENTION

Subjects who satisfy the inclusion/exclusion conditions will be randomly assigned to the control arm which provides standard of care for the surgical wound.

Interventions

EPIFLODEVICE

EPIFLO is a 3 ounce oxygen generator that continuously delivers 3 ml/hr of pure oxygen to the wound site, to enable tissue regenerative processes, thus driving closure of delayed-healing acute or chronic wounds.

Also known as: Transdermal Continuous Oxygen Therapy

Masking Details
Sham devices are not involved in this study. The surgeon will remain blinded to the subject's group assignment until after the wound is surgically closed in the operating room, and just prior to application of the dressing. A clinical professional, experienced in care of surgical wounds, will be appointed at the end of the study as a masked independent evaluator. This clinical professional will be blinded as to the treatment group of the subject.
