Negative Pressure Wound Therapy for the Prevention of Surgical Site

Status Recruiting

Clinical Trial 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.

Clinical Trial Description

The study is a non-blinded randomized control trial. The study examines the effect on wound healing and surgical site infection using negative pressure wound therapy compared to standard dressing in high-risk patients (BMI > 30, previous femoral cut-down). The investigators expected to find a lower surgical site infection rate in patients using the NPWT device.

Patients after giving informed consent will be randomized to receive either NPWT or standard wound therapy following tier lower-limb revascularization operative. Both will be applied under sterile conditions immediately post-operatively. The intervention will be left for 4-7 days depending on the discharge date and the standard dressing will be removed on post-operative day two.

The data will be analyzed with an intention to treat analysis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
