Negative Pressure Dressing After Saphenous Vein Harvest

This study has been completed.
Information provided by (Responsible Party):
Dr. Paul Fedak, University of Calgary Identifier:
First received: September 18, 2012
Last updated: November 30, 2015
Last verified: November 2015
This study will test the effectiveness of negative pressure wound therapy (using the VAC Prevena device, KCI Canada Inc.) applied to the saphenous vein harvest site after Coronary Artery Bypass Grafting (CABG). When initiated immediately after surgery, this intervention may decrease the incidence of wound infection and non-infectious wound complications. It may decrease wound discomfort and improve mobility and functional recovery of the leg.

Condition Intervention Phase
Coronary Artery Disease Complication of Coronary Artery Bypass Graft Wound Complication Device: Prevena device (Group A) Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Investigator, Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: Negative Pressure Dressing to Decrease the Incidence of Leg Wound Complications After CABG

Further study details as provided by Dr. Paul Fedak, University of Calgary:

Primary Outcome Measures:
  • Change from baseline ASEPSIS score of wound healing at 6 weeks. [ Time Frame: Baseline and 6 weeks ]
    The ASEPSIS quantitative wound scoring method will be used to assess patients' leg wound healing after saphenous vein harvesting for coronary artery bypass surgery.

Secondary Outcome Measures:
  • Total score of pain level. [ Time Frame: Baseline and 6 weeks ]
    Patients will be asked to evaluate the level of pain (using the Leg Incision Assessment Form) at the wound site after saphenous vein harvesting.

Enrollment: 64
Study Start Date: September 2012
Study Completion Date: March 2015
Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Prevena device (Group A)
Group A will have the VAC Prevena portable device applied to the saphenous vein harvest site after standard wound closure following coronary artery bypass surgery.
Device: Prevena device (Group A)
This portable device is applied to initiate negative pressure therapy to a wound site.
Other Names:
  • Prevena Incision Management System
  • Prevena 125
  • PRE1001.S Prevena Incision Kit
No Intervention: Conventional dressing (Group B)
Group B will have conventional dry dressing applied to the saphenous vein harvest site after standard wound closure following coronary artery bypass surgery.
