NCT02084017

Brief Summary

The purpose of this study is to investigate the current standard of wound care following vascular operations compared to to a negative pressure wound therapy (vacuum dressing) and the rate of surgical site infections (SSIs) in patients undergoing surgery to restore blood flow to the lower limb(s). Negative pressure wound therapy consists of a closed, sealed system that produces negative pressure (vacuum) to the wound surface. The device itself consists of open-cell foam that is sealed with an occlusive adhesive dressing (covers and sticks to the incision) and suction is maintained by connecting suction tubes to a vacuum pump and waste collector. The investigators objectives are to determine whether there will be any reduction in surgical site infection and this potential reduction will influence length of hospital stay, emergency room visits, antibiotic use and need for re-operation.

Study Arms (2)

Current Standard

ACTIVE COMPARATOR

Standard Tegaderm (3M Healthcare, St. Paul, MN) adhesive dressing applied under sterile conditions in the operating room following skin closure. Dressing changed post-operative day two and daily thereafter with daily inspection for infection by a physician.

Device: Standard Tegaderm (3M Healthcare, St. Paul, MN) adhesive dressing

Negative Pressure Wound Therapy

EXPERIMENTAL

A negative pressure therapy (Kinetic Concepts, Inc, San Antionio, Tex) device will be applied under sterile conditions post-operatively and placed on suction (125-150 cm H2O). The device will be removed on post-operative day 4-7 depending on day of discharge.

Device: Prevena (Negative Pressure Wound Therapy Device)

Interventions

No other details required.

Also known as: Prevena, Prevena Incision Management System, Negative Pressure Wound Therapy Device, Vacuum Therapy
