Evaluation of Novel Negative Pressure Wound Therapy Peel and Place Seven-Day Dressing

Introduction: While reticulated open cell foam (ROCF) is a well-established dressing for negative pressure wound therapy (NPWT), granulation tissue ingrowth can occur if the dressing is left in place longer than 72 hours, potentially causing wound bed disruption, bleeding, and pain upon dressing removal. Additionally, sizing the foam to fit the wound can be time-consuming. A novel integrated peel-and-place dressing (IPPD) with a polyurethane foam manifolding core and hybrid silicone-acrylic adhesive drape has been developed to remain in place for longer wear time. We report the results of a IPPD customer preference evaluation study.Methods:Ten patients being adjunctively treated with NPWT with traditional ROCF dressings were switched to NPWT with IPPD at one hospital in Chile. IPPD was applied in similar fashion by three clinicians: release liners were removed and dressing was placed on the wound bed as a wound cover dressing, with foam core portion extending ≥1 cm past the wound perimeter. IPPD was connected to the NPWT device via multi-lumen tubing, and -125 mmHg continuous pressure was applied. Dressing changes for patients 1-5 (3 pressure injuries, 1 diabetic foot ulcer, and 1 dehisced abdominal wound) were performed every 3 days, then switched to once per week, depending on clinical presentation. Dressings were changed on days 5 or 7, then moved to a 7-day schedule for patients 6-10 (3 traumatic and 2 post-surgical wounds). Patient 6 discontinued therapy on day 5.Results:Ten clinician surveys were completed. Time to apply IPPD was
